Abstract | The United Arab Emirates (UAE) presents a unique environment in which to breed horses with a non-physiological breeding season coupled with high temperatures and humidity for much of the year. This study aimed to describe bacterial isolates from the uteri of mares in the UAE and compare them to those reported elsewhere in the world. Bacterial antibiotic resistance was also analyzed to give a starting point for future monitoring. A total of 2,022 swabs taken over five breeding seasons from the endometrium (n = 1,350) or from uterine lavages (n = 672) were submitted for microbiological culture and antibiotic sensitivity testing. At 48 hours post-inoculation 616 of 2,022 (30.5%) of cultures showed microbial growth from which 690 isolates were identified. Most positive plates (548 of 616; 89%) grew one isolate; 68 cultures had two (62 of 616; 10.1%) or three (6 of 616; 1%) isolates. The most frequently isolated bacteria were β-hemolytic Streptococcus (36.5%; 252 of 690), E. coli (10.6%; 73 of 690), P. aeruginosa (10.1%; 70 of 690), K. pneumoniae (8.8%; 61 of 690) and Aeromonas hydrophila (4.1%; 28 of 690). The lowest level of antibiotic susceptibility for all isolates was shown by trimethoprim-sulphonamide (36.4%; 198 of 544), with amikacin showing the highest (76.1%; 271 of 356). A significant decrease in susceptibility to doxycycline, enrofloxacin, and erythromycin, but a significant increase for amoxicillin with clavulanic acid, was seen for β-hemolytic Streptococcus. Decreasing susceptibility of trimethoprim-sulphonamide between two time periods was seen for E. coli. Compared to other studies UAE-based mares had a high incidence of P. aeruginosa and K. pneumoniae isolates, whereas E. coli was represented far less frequently as an isolate. |
