Immunodeficient mice have a heightened susceptibility to pathogenic infection. To establish and infect the urinary tract, P. mirabilis must possess virulence factors to adapt to the local environment and to evade the host immune response. It is not a primary invasive pathogen and rarely causes infection in normal healthy individuals. Using PCR detection of resistance genes as the gold standard, multiple phenotypic methods may be needed to reach optimal sensitivity and specificity.225 Chromogenic agars can identify possible ESBL-producing isolates for further confirmation, with reported sensitivities of 95% to 97% and specificities of 94% to 95% when testing non-AmpC-producing organisms.226,227 Because of the wide range of genes encoding ESBLs, molecular approaches are limited to research settings, although multiplex rt-PCR and microarray technologies offer promise for accurate ESBL detection.228, Alexandre Chenal, ... Daniel Ladant, in The Comprehensive Sourcebook of Bacterial Protein Toxins (Fourth Edition), 2015. This rod shaped bacterium has the ability to produce high levels of urease. To test the Gram-negative and oxidase … Proteus vulgaris obtain energy and electrons from organic molecules. It has been suggested that swarming is important in the pathogenesis of CA-UTI and is essential for migration of P. mirabilis over all- silicone catheters. There are other species in the genus, e.g. Adenocarcinomas and a high incidence of chronic nephropathy and degenerative cardiomyopathy that was associated with exophthalmos have also been reported by others (Faith et al., 1997; Niewiesk and Prince, 2002). The enzyme is not related structurally or functionally to the IgA proteases produced by a number of important pathogens (e.g. The enzyme is not related structurally or functionally to the IgA proteases produced by a number of important pathogens (e.g. This chapter reiterates previous works discussed in the first edition and introduce current research being performed on this uropathogen. Preparation of McFarland Standards. If septicemia develops, suppurative or necrotic lesions, including septic thrombi, may be found in many organs, but the kidney is commonly affected. Proteus mirabilis 3. Proteus mirabilis cultures are maintained on slants of enriched nutrient agar such as dextrose phosphate. The standards are prepared in optically standardized tubes and are stoppered and sealed by dipping in melted paraffin. STICKLER, in Biomaterials and Tissue Engineering in Urology, 2009. It ferments glucose and sucrose but never lactose. Day, in, Laboratory Diagnosis and Therapy of Infectious Diseases, Principles and Practice of Pediatric Infectious Diseases (Fourth Edition), The Comprehensive Sourcebook of Bacterial Protein Toxins (Fourth Edition), Handbook of Proteolytic Enzymes (Third Edition), Diagnostic Microbiology and Infectious Disease. Since most research on non-E. coli uropathogens has been conducted on P. mirabilis, this organism serves a model of pathogenesis for these types of infections. Proteus mirabilis colonizes the intestinal tract of most humans and is commonly found in research mice unless specifically excluded. d)McConkey's Medium. This may accelerate the generation of alkaline urine and increase the deposition of crystalline material into the bladder and onto urinary catheters.65,66 Additional studies show that P. mirabilis has the ability to migrate successfully across sections of hydrogel-coated latex, hydrogel/silver-coated latex, silicone-coated latex and all-silicone catheters.67, Daniel H. Paris, ... Nicholas P.J. Hemolysins genetically related to HlyA have been identified very early on in Proteus mirabilis, Proteus vulgaris, and Morganella morganii [25,266]. Cholesterol cholelithiasis was reported as an incidental finding in wild cotton rats (Pence et al., 1978). Unknown #124B had the following morphology on a nutrient agar … By continuing you agree to the use of cookies. This group includes Rickettsia, which causes typhus fever, and Chlamydia trachomatis, which causes genitourinary infections (Hope et al 1993). Ten 10 × 75-mm tubes are numbered 1 through 10 and 0.5 ml of saline is added to tubes 2–10. However, most automated susceptibility testing systems cannot accommodate these lower breakpoints as the concentration of drug tested is not low enough for some of the cephalosporins. Infection in immunodeficient mice is typified by splenomegaly and focal necrotizing hepatitis. Mutants lacking organised flagellar structures fail to swarm successfully, suggesting these structures are important for migration and formation of multi-cellular rafts. Finally, 0.5 ml of Proteus in saline (5 × 108/ml) is added to each tube, and the tubes are mixed and centrifuged at 1000 rpm for 10 min. Isolation of Proteus from the nasopharynx may be associated with transient increase in fecal exposure, such as may occur during transportation (Franklin, 2010). It was named Proteus after an elusive character in Homer's Odyssey who was able to escape capture by changing its form. Uroliths harbor bacteria that can emerge as the uroliths dissolve. Peribronchiolar lymphoid hyperplasia is seen with some frequency in histologic sections of lungs from healthy animals. O. tsutsugamushi infection elicits antibodies that cross-react against a Proteus mirabilis OXK antigen preparation as detected by the Weil-Felix reaction and Western blotting [92]. Proteus mirabilis and Pseudomonas aeruginosa have been isolated concomitantly from cases of suppurative nephritis or pyelonephritis. Nonselective & Differential Media for Proteus: WL Nutrient Agar for microbiology, NutriSelect ™ Plus : Wallerstein Laboratory Nutrient Agar pricing. If septicemia develops, suppurative or necrotic lesions, including septic thrombi, may be found in many organs, but the kidney is commonly affected. There was one report of multiple pulmonary arterial thrombi, and another case of foreign body pneumonia (inhaled bedding), neither with associated clinical signs. Mark T. Whary DVM, PhD, DACLAM, ... Stephen W. Barthold DVM, PhD, Diplomate ACVP, in Laboratory Animal Medicine (Third Edition), 2015. Rotten cooked fishy odor: Proteus mirabilis produces a very distinct fishy odour. Rachael P.C. You have a mixed culture of these pathogens, which you … It also curdles milk with acid … concentric rings due to their motility. After the last injection, the mice are bled and the sera are pooled and tested for anti-Proteus activity by bacterial agglutination. Streptococcus, Neisseria; Chapters 278 and 682Chapter 278Chapter 682) which have exquisite specificity for human IgA1 and a limited number of proteins with sequence similarity to the IgA1 hinge region [2,7]. Confirmatory testing is warranted if the revised breakpoints cannot be implemented. Proteus mirabilis also exhibits a type of motility referred to as ‘swarming’, in which multi-cellular rafts of elongated, hyperflagellated swarmer cells form with the ability to move rapidly over solid surfaces. We use cookies to help provide and enhance our service and tailor content and ads. To prepare for use as antigen, 500-ml flasks of broth are inoculated and allowed to grow … In patients with long-term catheterisation, P. mirabilis has been isolated from 40% of urine samples.57 Genotyping of P. mirabilis isolated from catheterised urinary tracts suggests that strains are remarkably stable, with the same genotype persisting in the patient’s urinary tract despite many catheter changes, courses of antibiotics and even catheter-free periods.58, Genotyping also determined that the P. mirabilis strains isolated from bladder stones and encrusted catheters of the same patient were identical, and that the majority of patients were infected with genetically distinct strains.59Proteus mirabilis is an enteric organism and subsequent analysis showed that bacteria isolated from faecal material and catheter biofilms of the same patient were identical, indicating that catheter encrustation of long-term catheterised patients occurs from P. mirabilis originating from their own faecal flora.60, All types of Foley catheters are vulnerable to P. mirabilis biofilms. Its natural habitat is the intestinal tract. Other bacteria in the bacillus group include Corynebacterium diphtheriae, which causes diphtheria, Pseudomonas aeruginosa, and M. tuberculosis, which causes TB. All E. coli, K. pneumoniae, K. oxytoca, and Proteus mirabilis should be screened for the presence of ESBLs if they demonstrate resistance or reduced susceptibility to extended-spectrum cephalosporins. 3-27 INFLUENCE OF AGE ON PIGMENT PRODUCTION A Serratia marcescens grown on Sheep Blood Agar … Proteus mirabilis is an extraordinary microbe. Michael A. Kerr, Robert Belas, in Handbook of Proteolytic Enzymes (Third Edition), 2013. There are opportunistic pathogens that can infect the lungs, or wounds, and frequently cause urinary tract infections. Two different cultures grew and were visibly observed, isolated, and ... careful order of tests was followed that led to Proteus … Nutrient Agar is a general purpose, nutrient medium used for the cultivation of microbes supporting growth of a wide range of non-fastidious organisms. TABLE I. Many strains of P. mirabilis produce … Angelos et al. Immunodeficient mice have a heightened susceptibility to pathogenic infection. A classification of pathogens is shown in Fig. On Salmonella-Shigella (SS) agar, Proteus usually smells like “rotten cooked fish”. Proteus pyelonephritis is characterized by abscessation and scarring. Both phenotypic and molecular methods can be used to detect ESBLs.67,218 A widely used, highly accurate phenotypic method employs combination disks containing clavulanic acid with either ceftazidime or cefotaxime, versus the cephalosporins alone. Q - You are suspecting Proteus vulgaris is present on a nutrient agar plate. All E. coli, K. pneumoniae, K. oxytoca, and Proteus mirabilis should be screened for the presence of ESBLs if they demonstrate resistance or reduced susceptibility to extended-spectrum cephalosporins. ⇒ Oxygen requirements – Pseudomonas aeruginosa (P. aeruginosa) is an obligate aerobic bacterium i.e. This is an extracellular protease that can be isolated when P. mirabilis is grown on media containing a suitable substrate such as skim milk agar [1]. (Elangbam, 1990), and Trichinella spiralis (Holliman and Meade, 1980). hanging drop, flagella stain, and stab cultures. What methods can be used to determine motility? 9-3. [271] cloned the structural gene MbxA and characterized the mbx operon [272] that harbors the putative acyltransferase MbxC and the secretory proteins MbxB and MbxD, as well as a TolC homologue. Closely related operons, designated mbvCABD/tolC and movCABD/tolC, have been identified in Moraxella bovoculi and M. ovis, respectively [273]. Proteus mirabilis and Pseudomonas aeruginosa have been isolated concomitantly from cases of suppurative nephritis or pyelonephritis. e) Lowenstein Jensen (LJ) medium. This is mixed and 0.5 ml is transferred to tube 3, and so on. Genus and Species: Proteus mirabilis Domain: Prokaryote Optimal Growth Medium: Nutrient Agar Optimal Growth Temperature: 37° C Package: MicroKwik Culture® Vial Biosafety Level: 2 Gram Stain: Gram-Negative Shape: Bacillus (rod-shaped) In 2010, CLSI proposed lower cephalosporin breakpoints.220 Implementation of these lower breakpoints precludes the need for confirmatory testing as ESBL-producing organisms will be interpreted as resistant. It is part of the faecal flora of humans and many other mammals. Physical injuries can be seen secondary to escape behavior. Anaerobic bacilli include Clostridium tetani, which causes tetanus, and C. difficile, which causes pseudomembranous colitis. Michael A. Kerr, Robert Belas, in Handbook of Proteolytic Enzymes (Third Edition), 2013. Jordan, Lindsay E. Nicolle, in, Biofilms in Infection Prevention and Control, Production and Assay of Murine Anti-Allotype Antisera, Daniel H. Paris, ... Nicholas P.J. Proteus has been associated with ulcerative lesions in the gastrointestinal tract of immunodeficient mice. To the first tube, 0.95 ml of saline and 0.05 ml of serum are added. Infected animals lose weight, develop diarrhea, and die within several weeks. The functional properties and pore-forming properties of the RTX determinants have been investigated in lipid-bilayer membranes and erythrocytes and were showed to be similar to that of HlyA [42,267–269]. Proteus mirabilis: Nutrient Agar Columbia Colistin Nalidixic Acid Agar Decarboxylase Broth Moeller Ornithine Phenol Red Broth Base Lactose Phenol Red Broth Base Maltose Phenol Red Broth Base Mannitol Phenylalanine Agar Spirit Blue Agar Triple Sugar Iron Agar Urea Agar … Proteus penneri 5. In addition, the highly organised structure of multi-cellular rafts enables P. mirabilis to initiate CA-UTI by migration over catheter surfaces from the urethral meatus into the bladder.64 The transformation of P. mirabilis from small swimming bacilli into elongated, highly flagellated swarmer cells is accompanied by a substantial increase in the production of urease. Among the virulence components known to be expressed by the urinary tract pathogen Proteus mirabilis is a metalloprotease referred to as mirabilysin. With basic … This operon is absent in nonhemolytic M. bovis strains. Proteus mirabilis on blood agar. This chapter reiterates previous works discussed in the first edition and introduce current research being performed on this uropathogen. Fatty vacuolization of centrilobular hepatocytes has been described in control animals on a toxicological study (McMurry et al., 1995). In addition to the two main groups, there are the spirochete group and a further group of organisms that are neither viruses nor bacteria, but something in between. Culture recovery of Proteus mirabilis as a predominant or single isolate confirms an opportunistic local or systemic infection. The highest dilution in which agglutination has occurred is taken as the titer of the antiserum. You are able to perform 3 procedures to confirm this identifcation, choose 3 tests and identify their order. Specific monoclonal and polyclonal antibodies may be used to identify Orientia by direct immunofluorescence assay (DFA) and immunoperoxidase (IP) techniques [93–96]. [270] first identified in the culture supernatant of M. bovis, a possible HlyA-related toxin of 110 kDa with hemolytic and cytotoxic activities that might be involved in the pathogenesis of infectious bovine keratoconjunctivitis. [271] cloned the structural gene MbxA and characterized the mbx operon [272] that harbors the putative acyltransferase MbxC and the secretory proteins MbxB and MbxD, as well as a TolC homologue. To prepare for use as antigen, 500-ml flasks of broth are inoculated and allowed to grow for 48 hr at 37°C. Proteus mirabilis, P. vulgaris are widely recognised as human pathogens.

Barthold DVM, PhD, Diplomate ACVP, in, Laboratory Animal Medicine (Third Edition), Proteus mirabilis biofilm formation and catheter design, Biomaterials and Tissue Engineering in Urology, Preventing Infection Associated with Urethral Catheter Biofilms, Rachael P.C. The functional properties and pore-forming properties of the RTX determinants have been investigated in lipid-bilayer membranes and erythrocytes and were showed to be similar to that of HlyA [42,267–269]. Proteus:-it forms pale translucent colonies with fishy smell.. There are other species in the genus, e.g. c)Chocolate agar. [270] first identified in the culture supernatant of M. bovis, a possible HlyA-related toxin of 110 kDa with hemolytic and cytotoxic activities that might be involved in the pathogenesis of infectious bovine keratoconjunctivitis. Mutants lacking organised flagellar structures fail to swarm successfully, suggesting these structures are important for migration and formation of multi-cellular rafts. Agglutination is defined as the presence of a large flocculant precipitate when the tube is gently tapped. Posterior paralysis, presumably secondary to spinal fracture, has been observed in animals that were jumping up against the top of their cage (Mitchell, 2009). It is not a primary invasive pathogen and rarely causes infection in normal healthy individuals. The annotation of the P. mirabilis genome and transcriptome profiling have allowed for better understanding of the disease process caused by this bacteria in the urinary tract. Urinary tract infections are commonly caused by Staphylococcus saprophyticus and Escherichia coli, less commonly caused by Proteus mirabilis. The virulence factors known to be involved in UTIs caused by P. mirabilis include adhesins, motility, biofilm formation, immunoavoidance, toxins and nutrient acquisition. (Breshears et al., 2009; Johnson et al., 2007, 2008), Hypocristata terctercera (Durette-Desset and Guerrero, 2006), Strongyloides sp. The flagellar filaments of P. mirabilis are highly organised during raft migration and are interwoven to form helical connections between adjacent swarmer cells. (Elangbam et al., 1993). In addition, the highly organised structure of multi-cellular rafts enables P. mirabilis to initiate CA-UTI by migration over catheter surfaces from the urethral meatus into the bladder.64 The transformation of P. mirabilis from small swimming bacilli into elongated, highly flagellated swarmer cells is accompanied by a substantial increase in the production of urease. 3-4 mm. It produces a potent urease and so may contribute to development of struvite urolithiasis. Nematode infections include Hepatozoon spp. It is an opportunist, given a debilitated host it can produce infection. Colony of Staphylococcus aureus on nutrient agar Golden yellow large i.e. Reports of bacterial infections include Bartonella spp. The annotation of the P. mirabilis genome and transcriptome profiling have allowed for better understanding of the disease process caused by this bacteria in the urinary tract. It can be isolated from sewage or polluted soils and waters with ease. Jordan, Lindsay E. Nicolle, in Biofilms in Infection Prevention and Control, 2014, Proteus mirabilis is not usually found during early colonisation of the catheterised urinary tract, so is uncommon in patients undergoing short-term catheterisation.56 The longer a catheter is in place, however, the more likely it is that P. mirabilis will be isolated from the urine. Proteus vulgaris Jane Buckle RN, PhD, in Clinical Aromatherapy (Second Edition), 2003. The unknown microbe #124A was determined to be Proteus vulgaris. Proteus mirabilis is a common cause of upper and lower UTIs in dogs as well as otitis externa and uncommonly pyoderma. Most automated susceptibility testing systems also include a screen for ESBL production, with acceptable sensitivity and specificity. Morganella (previously Proteus) morganii is also a commensal of the intestinal tracts of humans or animals that can be implicated in postoperative and other nosocomial infections. Closely related operons, designated mbvCABD/tolC and movCABD/tolC, have been identified in Moraxella bovoculi and M. ovis, respectively [273]. Useful for culturing urine specimens which may contain large number of Proteus … D.J. vulgaris is arranged singly, in pairs, or in short chains and sometimes in clusters.Motility – Proteus Vulgaris is an actively motile bacterium and well known for the swarming growth on an ordinary medium like NAM.Flagella – Pr. Proteus mirabilis also exhibits a type of motility referred to as ‘swarming’, in which multi-cellular rafts of elongated, hyperflagellated swarmer cells form with the ability to move rapidly over solid surfaces. Gray et al. To establish and infect the urinary tract, P. mirabilis must possess virulence factors to adapt to the local environment and to evade the host immune response. In 2010, CLSI proposed lower cephalosporin breakpoints.220 Implementation of these lower breakpoints precludes the need for confirmatory testing as ESBL-producing organisms will be interpreted as resistant. Its natural habitat is the intestinal tract. After 48 hours of incubation, nutrient agar plate showed two distinct colonies. A species of considerable medical … Daniel H. Paris, ... Nicholas P.J. Monoclonal antibodies useful for identification are mostly directed against the major serotyping proteins: 47-, 56- and 110-kDa protein antigens [25,97]. Proteus myxofaciens 4. Spreading and light yellow. Most automated susceptibility testing systems also include a screen for ESBL production, with acceptable sensitivity and specificity. Proteus mirabilis is a frequent cause of these infections in individuals with abnormal urinary tracts or using indwelling catheters (CAUTIs). f) … Proteus mirabilis on Bile Esculin Agar. Isolation of organism With basic microbiological technique, samples believed to contain Proteus are first incubated on nutrient agar to form colonies. ⇒ There are various culture media used for the cultivation of Pseudomonas aeruginosa (P. aeruginosa) in the laboratory and most commonly the Nutrient Agar medium and MacConkey Agar … Both phenotypic and molecular methods can be used to detect ESBLs.67,218 A widely used, highly accurate phenotypic method employs combination disks containing clavulanic acid with either ceftazidime or cefotaxime, versus the cephalosporins alone. Viral infections include West Nile virus (Dietrich et al., 2005), Hantavirus (Mantooth et al., 2001), and vesicular stomatitis virus (Jiménez et al., 1996). 25.3 CULTURE CHARACTERISTICS These can grow on ordinary media like nutrient agar with a characteristic fishy or seminal odour. Jordan, Lindsay E. Nicolle, in, Biofilms in Infection Prevention and Control, Daniel H. Paris, ... Nicholas P.J. If the zone size of inhibition around the combination disk is ≥5 mm around the cephalosporin alone, the isolate is considered to be an ESBL-producer (Figure 290-2).67,218 Other phenotypic approaches include Etests and MIC tests that detect ≥3-fold lowering by clavulanic acid of MIC of the extended-spectrum cephalosporin. This is a series of tubes containing various amounts of BaSO4 precipitate, the turbidity of which corresponds to the turbidity of known concentrations of bacteria (Table I; see also Campbell et al., 1970). Streptococcus, Neisseria; Chapters 278 and 682Chapter 278Chapter 682) which have exquisite specificity for human IgA1 and a limited number of proteins with sequence similarity to the IgA1 hinge region [2,7]. Wild cotton rats have been reported to be susceptible to naturally occurring infections from a number of organisms. It is an opportunist, given a debilitated host it can produce infection. Since most research on non-E. coli uropathogens has been conducted on P. mirabilis, this organism serves a model of pathogenesis for these types of infections. (Abbot et al., 2007), and Borrelia burgdorferi (Burgdorfer and Gage, 1987; Oliver et al., 2003). What type of growth pattern was Proteus mirabilis in the nutrient agar slant? Once the two colonies were found, they were isolated on separate agars for growth. Spontaneous gastric adenocarcinoma has been reported (Kawase and Ishikura, 1995). Mice carrying the appropriate Ig-1 allele (see Table II) are immunized with three to four intraperitoneal injections of 109 Proteus organisms in saline, spaced 7–10 days apart. Unfortunately for us it has many properties that make it ideally suited to life in the catheterized urinary tract (Mobley, 1996). However, most automated susceptibility testing systems cannot accommodate these lower breakpoints as the concentration of drug tested is not low enough for some of the cephalosporins. Urease from P. mirabilis can hydrolyse urea several times faster than urease produced by other species.62 Experimental work has shown that urease-negative P. mirabilis mutants fail to form crystalline biofilms; whereas urease-positive strains, which lack flagella or the ability to swarm, are still able to encrust and block catheters, similar to wild-type parent strains.55,63.

It has been suggested that swarming is important in the pathogenesis of CA-UTI and is essential for migration of P. mirabilis over all- silicone catheters. Swarming-deficient mutants were attenuated for migration over hydrogel-coated latex catheters, but those capable of swimming motility were able to move over and colonise these surfaces. Among the virulence components known to be expressed by the urinary tract pathogen Proteus mirabilis is a metalloprotease referred to as mirabilysin. Hemolysins genetically related to HlyA have been identified very early on in Proteus mirabilis, Proteus vulgaris, and Morganella morganii [25,266]. Proteus mirabilis is a frequent cause of these infections in individuals with abnormal urinary tracts or using indwelling catheters (CAUTIs). Shape – Proteus Vulgaris is a short, straight rod shape (bacillus) bacterium.Size – The size of Proteus Vulgaris is about 1–3 µm × 0.5 µm (micrometer).Arrangement Of Cells – Pr. STICKLER, in Biomaterials and Tissue Engineering in Urology, 2009. The first procedure completed was the growth of two isolation streaks on nutrient agar plates from mixed culture 102. Proteus mirabilis is an extraordinary microbe. Using PCR detection of resistance genes as the gold standard, multiple phenotypic methods may be needed to reach optimal sensitivity and specificity.225 Chromogenic agars can identify possible ESBL-producing isolates for further confirmation, with reported sensitivities of 95% to 97% and specificities of 94% to 95% when testing non-AmpC-producing organisms.226,227 Because of the wide range of genes encoding ESBLs, molecular approaches are limited to research settings, although multiplex rt-PCR and microarray technologies offer promise for accurate ESBL detection.228, Alexandre Chenal, ... Daniel Ladant, in The Comprehensive Sourcebook of Bacterial Protein Toxins (Fourth Edition), 2015. It is part of the faecal flora of humans and many other mammals. Many strains of P. mirabilis produce this protease which has broad substrate specificity but has been referred to as an IgA protease because of its activity on both serum and secretory forms of IgA1 (immunoglobulin A1) and IgA2 [2], as well as IgG [3–6]. Septic thrombi can occur, however, in many tissues. Ascending lesions may occur following urinary stasis, but hematogenous spread cannot be ruled out. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Proteus mirabilis cultures are maintained on slants of enriched nutrient agar such as dextrose phosphate. Septic thrombi can occur, however, in many tissues. 1. However, the O. tsutsugamushi antigen responsible for eliciting these antibodies has not been identified. Melissa B. Miller, Peter H. Gilligan, in Principles and Practice of Pediatric Infectious Diseases (Fourth Edition), 2012. Sweet grape-like scent Pseudomonas aeruginosa produces a sweet grape-like scent, so wound dressings and agar … Proteus mirabilis is a ubiquitous gram-negative organism that can remain latent in the respiratory and intestinal tracts of normal mice (Percy and Barthold, 2007). E. coli on Nutrient agar, Blood agar, MacConkey agar, EMB agar, m-ENDO agar, MHA, VRBA, CLED agar and Liquid media. Proteus hauseri 2. The term Proteus … If the zone size of inhibition around the combination disk is ≥5 mm around the cephalosporin alone, the isolate is considered to be an ESBL-producer (Figure 290-2).67,218 Other phenotypic approaches include Etests and MIC tests that detect ≥3-fold lowering by clavulanic acid of MIC of the extended-spectrum cephalosporin. However, cross-reactivity of anti-mouse and rat antibody conjugates from a commercial multiplex fluorescent immunoassay with cotton rat IgG is low, which could result in under-reporting of infections (Steffen, 2009).
