This retrospective study characterized the identity and antibiotic resistance profiles of staphylococci isolated from cats between 2001 and 2014. The results demonstrate a high and increasing prevalence of multi-drug antibiotic resistance and an increasing prevalence of methicillin resistance in Staphylococcus intermedius group bacteria isolated from cats during this time.

The aim of this study was to determine the frequency of occurrence of most common human pathogenic Campylobacter species in dogs and cats in Styria, Austria. Results show a very low proportion of C. spp.-positive samples (5.9%) in microbiological culture with Campylobacter jejuni as the most common type. Furthermore, the ratio of C. species between young and adult, as well as healthy and diarrhoeic animals, was analysed. There is a higher prevalence of Campylobacter jejuni in kittens and in diarrhoeic animals in this study. Finally, the obtained strains of Campylobacter jejuni for antibiotic sensitivity testing to assess the resistance situation. Several antibiotics display high resistance rates.

A survey was sent to veterinarians in Arizona to identify and investigate patterns of antimicrobial use following surgically treated canine pyometra.

The emergence of methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus pseudintermedius (MRSP) have a significant health impact on occupational people and pet owners. Although the occurrence of MRSA and MRSP in humans and animals has been reported in many other countries, the information on the magnitude of S. aureus and S. pseudintermedius infection in dogs in Bangladesh and their antimicrobial resistance pattern is limited, if not absent. This manuscript, for the first time, describes the circulation of mecA gene bearing S. pseudintermedius in dogs in Bangladesh.

The incidence of bacteraemia in 55 neutropaenic dogs undergoing chemotherapy was found to be 12.3%. The incidence in febrile and afebrile groups was not significantly different. Of positive blood cultures, 42.9% were multi-drug–resistant organisms highlighting the value of blood cultures in this patient population.

An 11-year-old Swedish warmblood gelding was diagnosed with a cystolith which was removed by cystotomy. Seven days after surgery the horse presented with pyrexia, dullness, and colic due to a right-sided pyelonephritis caused by an ESBL-producing Enterobacter cloacae complex bacteria with resistance against beta-lactams, aminoglycoside, and trimethoprim-sulfonamide classes. Treatment included prolonged oral antimicrobials according to susceptibility testing results (enrofloxacin), non-steroidal anti-inflammatory drugs, fluid therapy and gastric ulcer prophylaxis. The horse recovered successfully although unilateral renal scarring occurred.

Prophylactic perioperative antimicrobial protocols in equine practice deserve periodic reconsideration due to increased antimicrobial resistance. Prolonged antimicrobial usage beyond the time of surgery was unnecessary to prevent septic synovitis following synovial endoscopy in this case population and was furthermore associated with an increased risk of gastrointestinal complications.

This is the first report of the emergence of the tmexCD3-toprJ3 gene in Pseudomonas juntendi and Proteus terrae isolated from a pig farm in China. The tmexCD3-toprJ3 efflux pump cluster conferred multidrug resistance, including resistance to tigecycline, demonstrating pathogenicity and transmission.

This is the first description of the prevalence of A. viridans in Korean swine herds and the fetuses demonstrate the considerable prevalence of A. viridans in Korea.

This study details success conditions of an antimicrobial stewardship program in animal agriculture. Based on data provided by complementary and independent monitoring tools, success could be assessed on both usage and resistance. Results highlight the strong relationship between cephalosporins usage and resistance in pig production, supporting a containment perspective through usage restriction.

Increasing numbers of carbapenemase-producing, multidrug-resistant, highly pathogenic Klebsiella pneumoniae pose a serious risk to the health of people and poultry in Bangladesh. To reduce the prevalence Klebsiella pneumoniae isolates in poultry which have harbored beta-lactamase genes and quinolone resistance genes, a combination of antibiotics such as doripenem, meropenem, cefoxitin, and polymyxin B is recommended, followed by the use of readily available heavy metals Cr>Co>Cu>Zn beyond their toxic metal. Antibiotics such as ampicillin, doxycycline, tetracycline, gentamycin, and ciprofloxacin have already lost their typical efficacy against the isolates examined, therefore we must be cautious when using them to treat bacterial diseases in poultry.

Chicken and Turkey meat samples harboured the highest contamination rates. C. jejuni and C. coli isolates harboured a high resistance rate against some antibiotics, which was accompanied by the high distribution of most antimicrobial resistance-encoding genes.

This is the first study in Bangladesh to detect multidrug-resistant (MDR) and multiple antibiotic-resistant (MAR) Enterococcus faecium along with their corresponding resistance genes from healthy broilers. Our findings indicated that faecal materials of broilers harbour a high level of MDR and MAR E. faecium and multiple antibiotic resistance genes in those isolates. The results obtained from our study show severe health risks to both animals and humans.

Winter season, absence of specific shoes for staff, and use of antibiotics without veterinarian's prescription were the significant risk factors of MDR-E. coli infection in broiler chickens.

A very high resistance of the E. coli isolates against levofloxacin (81.6%), doxycycline (78.1%), cefotaxime (78.1%), and ciprofloxacin (70.2%) was observed.

Similar pattern of resistance phenotype of E. coli was observed among broiler chickens, farm workers, and farm sewage, and about 76% of the isolates demonstrated multidrug resistance.

This cross-sectional study was aimed to investigate the zoonotic Salmonella strains circulating in the broiler farm environment with their detailed antimicrobial resistance profiling. Out of the 350 samples, prevalence of Salmonella was 24% and multidrug-resistant (MDR) Salmonella was 94%. There is a great risk to secure healthy poultry products due to the circulation tetA, tetB, tetC, bla_TEM, bla_CTX-M and Sul-I antimicrobial resistance genes in these MDR zoonotic Salmonella.
