Characteristics of Extended-Spectrum ?-Lactamase-Producing Escherichia coli From Dogs and Cats Admitted to a Veterinary Teaching Hospital in Taipei, Taiwan From 2014 to 2017.

ABSTRACT: Extended-spectrum ?-lactamases (ESBLs) are enzymes that mediate resistance to newer ?-lactam antibiotics, including extended-spectrum cephalosporins and monobactams. The production of ESBL is primarily plasmid mediated, and such plasmids often comprise the genes that encode resistance to other classes of antimicrobials, such as aminoglycosides and fluoroquinolones. Therefore, ESBL-producing microorganisms leave clinicians with limited therapeutic options in both human and veterinary medicine. Compared with human medicine, information regarding ESBL-producing microorganisms is limited in veterinary medicine. We screened for ESBL-producing Escherichia coli in dogs and cats admitted to National Taiwan University Veterinary Hospital, Taipei, from 2014 to 2017 and further analyzed the genotypes and phylogenetic traits of these ESBL producers. Double disk tests specified by the Clinical and Laboratory Standards Institute were performed on 283 E. coli isolates and revealed a total of 65 E. coli (54 from dogs and 11 from cats) with the ESBL phenotype (22.8%). bla CTX-M-1 group and bla CTX-M-2group were the most commonly identified ESBL gene groups. bla CTX-M-55 was the main ESBL gene within the bla CTX-M-1group, whereas the bla CTX-M-2group contained only bla CTX-M-124. The ESBL-producing E. coli were all resistant to ampicillin. The resistance rate to ceftiofur, doxycycline, enrofloxacin, and ciprofloxacin was 93.8, 73.8, 80, and 78.5%, respectively. Of the antibiotics tested, greater sensitivity to imipenem and gentamicin was noted. Multilocus sequence typing indicated that ST457, ST131, and ST648 were the most common sequence types. Our study identified eight ST131/O25b isolates, which is a global zoonotic clone of public health concern. The major ESBL genes of these clones were bla CTX-M-174 and bla CTX-M-194. Because companion animals such as dogs and cats are in close contact with humans, the characterization of ESBL producers originating from them is crucial from the perspective of both public health and veterinary medicine.

Project description:ObjectivesThe aim of this study was to evaluate possible risk factors for death in traumatized cats based on the clinicoepidemiological profile, the Animal Trauma Triage (ATT) scale score and the Modified Glasgow Coma Scale (MGCS) score at the time of presentation to the hospital.MethodsThis was a cross-sectional study involving cats admitted to the emergency sector (ES) and the surgical clinic sector (SCS) of a veterinary teaching hospital (VTH) in northeastern Brazil over a 12-month period (2018-2019). Probable risk factors associated with non-survival after trauma were analyzed by calculating the prevalence ratio. The prediction of non-survival was evaluated by analyzing the receiver operating characteristic (ROC) curve employing the ATT scale score, MGCS score and rectal temperature.ResultsIn 1 year, 89 traumatized cats were admitted to the VTH, of which 90% (n = 80) were young, 54% (n = 48) were male, 79% (n = 70) were intact, 59% (n = 53) were indoor cats and 92% (n = 82) were considered as mixed breed. Blunt trauma was the most prevalent cause of injuries, reported in 76% (n = 68) of the cats. Accidents involving falls (30%; n = 27) that affected the pelvic limbs (50.6%) were the most commonly reported. The prevalence of death among cats admitted to the ES was 9.44 times higher than that of animals treated at the SCS. Trauma as result of being run over and chest trauma were associated with a higher probability of death. Most of the animals that died had a lower rectal temperature than those that survived. The ATT scale score, MGCS score and rectal temperature were predictive of mortality.Conclusions and relevanceRectal temperature, ATT scale score and MGCS score were effective predictors of an unfavorable prognosis and point to the need for emergency procedures. Hypothermia, being run over and chest trauma were associated with a higher risk of mortality. Our findings highlight the importance of prompt and effective care for these conditions.
