Enrofloxacin is one of the most widely used antibacterial drugs in feline medicine. This study investigated the effects of enrofloxacin on in vitro feline spontaneous myometrial contractility at different sexual stages. Uterine samples of the 20 queen cats at different sexual periods were placed in a tissue bath, and in vitro spontaneous stretch-induced myometrial contractions were recorded for 10 min. The tissue bath was adjusted for cumulative enrofloxacin concentrations of 0.25 mM, 0.50 mM, 1.00 mM, and 2.00 mM, respectively. Myometrial contractions were recorded for 10 min after each dose was adjusted in the tissue bath. It was observed that enrofloxacin caused a significant decrease in the peak amplitude and area under curve, while causing an increase the frequency of stretch-induced myometrial contractions in a dose dependent manner in vitro at all sexual stages. The current preliminary study concluded that enrofloxacin has an inhibitory effect on in vitro feline uterine myometrial activity at all sexual stages. It is recommended to take this medical effect into consideration and apply enrofloxacin and uterotonics together in treatment of uterine infections in feline medicine.

Background: Intrauterine mixed infections are an important problem in cattle breeding. In this study, we aimed to determine the mixed bacteriological isolation rates from the uterus of cows with clinical metritis and to reveal the relationships between the bacteria that isolated together. Methods: For this purpose, sterile swabs were taken from 490 uterus obtained from cattle slaughtered due to infertility in three slaughterhouses and used them to perform microbiological tests. After evaluating the data, it was determined that the bacterial isolation rate from uterus with clinical metritis was 76.14% (n = 268). Results: The rates for 1, 2, 3, 4, and 5 bacteria isolated from the uterus with clinical metritis were 48.13%, 33.96%, 15.30%, 2.24%, and 0.37%, respectively. The isolation rates for Trueperella pyogenes, Fusobacterium necrophorum, and Escherichia coli alone from the uterus with clinical metritis were 27.08%, 28.00%, and 16.51%, respectively. In uterus with clinical metritis, Staphylococcus aureus (16.67%) was the most commonly isolated bacteria with T. pyogenes, Clostridium spp. (16%) co-isolated with F. necrophorum, and coagulase-negative staphylococci (16.51%) and Bacillus spp. (16.51%) were detected with E. coli. Conclusion: As a result, it was concluded that when evaluating the microbiological results for cows with clinical metritis, mixed infections should be taken into more consideration, and the characteristics of the bacteria that isolate together should be considered during the treatment of mixed infections.
