Monitoring the Prevalence of Antimicrobial Resistance in Companion Animals: Results from Clinical Isolates in an Italian University Veterinary Hospital

Transboundary and Emerging Diseases (2023)

Raffaele Scarpellini Giammarco Assirelli Massimo Giunti Erika Esposito Elisabetta Mondo

The role of companion animals in the spread of antimicrobial resistance (AMR) is still not well known. As part of a wider surveillance system, this study aimed to provide data about AMR in bacterial isolates from infections in companion animals referred to an Italian University Veterinary Hospital (VUH) from November 2020 to September 2022. A total of 940 isolates were identified with MALDI-TOF MS and subsequently the antimicrobial susceptibility test (AST) for 12 antimicrobials was performed. Urine was the most commonly submitted specimen (54.92%) and Escherichia coli was the most common bacterial species isolated (36.06%). Out of the 940 isolates, 747 (79.47%) were nonsusceptible to at least one drug (AMR), while 420 (44.68%) were considered multidrug resistant (MDR). The highest nonsusceptibility percentages were recorded for clindamycin (59.65 %), erythromycin (58.96 %), ampicillin (52.85%), and enrofloxacin (48.19%). Alarming percentages were recorded also for ceftiofur (25.51%), amoxicillin–clavulanate (22.99%), and piperacillin–tazobactam (15.85%). In multivariable risk factors analysis, previous use of invasive devices (

p < 0.01

in both cases) and previous use of antimicrobials (

p < 0.01

in both cases) were statistically related with higher AMR and MDR percentages. Apart from a general evaluation, the study focused on specific bacterial species (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.) and specimens (blood cultures, urine from suspected healthcare-associated urinary tract infections, and surgical site infections), showing in both cases higher AMR and MDR percentages compared to average. These data highlight the urgency to further investigate AMR spread in pets and how passive surveillance systems can be effective tools to monitor AMR and to optimize antimicrobial use.

Typing ofCampylobacter jejuniIsolated from Turkey by Genotypic Methods, Antimicrobial Susceptibility, and Virulence Gene Patterns: A Retrospective Study

Foodborne Pathogens and Disease (2015)

Gerardo Manfreda Antonio Parisi Alessandra De Cesare Domenico Mion Silvia Piva

In this retrospective study, typing ability, discriminatory power, and concordance between typing results obtained on 123 Campylobacter jejuni turkey isolates, collected in 1998, within 14 different farms, applying multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE), antibiotic resistance profile, and virulence gene pattern, were assessed and compared. Overall, 33 sequence types, 28 pulsotypes, 10 resistotypes, and 5 pathotypes were identified. MLST and PFGE showed the better discriminatory ability (i.e., Simpson's diversity index >0.90) as well as unidirectional (i.e., Wallace and adjusted Wallace coefficients >0.86) and bidirectional (i.e., adjusted Rand coefficient >0.60) concordance. Moreover, both methods showed a good unidirectional and bidirectional concordance with the resistotype. On the contrary, the congruence of both genotyping methods and resistotype with the pathotype seemed due to chance alone. A clonal relationship was identified among 66.7% of the isolates. Furthermore, 59.7% of the investigated isolates were resistant to two or more antimicrobials and 92% to tetracycline. All the isolates harbored cadF and pldA genes, whereas a flaA gene product and a cdtB gene product were amplified from 85.4% and 79.7% of the isolates, respectively, using the primers designed by Bang et al. (2003). The results of this study clarify the level of genetic diversity among the C. jejuni originating from turkeys. MLST level of correlation with PFGE, resistotype, and pathotype is assessed. This result supports the selection of type and number of typing methods to use in epidemiological studies. Finally, the identification of clonal complexes (i.e., groups of profiles differing by no more than one gene from at least one other profile of the group using the entire Campylobacter MLST database) shared between turkey and human isolates suggests that turkeys could be a possible source of Campylobacter infection.

PRESENCE OF ARCOBACTER SPP. IN IN-LINE MILK FILTERS: AN EMERGING AND SIGNIFICANT MICROBIOLOGICAL HAZARD IN FOOD

Italian Journal of Food Safety (2011)

Federica Giacometti Andrea Serraino Daniela Florio Silvia Piva Raffaela Riu

While a study on the presence of foodborne pathogens in in-line milk filters of Italian dairy farms authorized for production and sale of raw milk was in progress, we fortuitously detected and isolated some Arcobacter spp. during routine analysis for thermotolerant Campylobacter. This observation suggested that extraordinary and non-standardized growth conditions for detection and identification were needed to provide more information and data on this poorly known emergent zoonotic pathogen. The presence of Arcobacter butzleri and Arcobacacter cryaerophilus in milk filters of dairy farms authorized for production and sale of raw milk poses a risk for public health and rather suggests that raw milk samples should also be examined for Arcobacter contamination. While the role of Arcobacter spp. in human disease awaits further evaluation, a precautionary approach is advisable and control measures to prevent or to eliminate the hazard of Arcobacter spp. in food and from the human food chain should be encouraged as well as more epidemiological studies. With this article, we review the literature of this organism in order to focus the relevant information to food safety.
