Fungal infection of reproduction system of dairy cattle have not been received much more attention. The aim of this study was to determine the fungal infection of Holstein dairy cows with reproductive disorders or healthy. Fungal isolates of cervicovaginal fluids of 176 Holstein dairy cows were collected by using the double rod swabs for cervix and the sterilized cotton swabs for discharges of vagina. They were evaluated for fungal infections. The treatment group included 70 dairy cows with reproductive diseases, such as abortion, repeat breeder, endometritis, metritis, retention of fetal membrane, dystocia, cervicitis, and vaginitis. The control groups were included 42 healthy non-pregnant cows and 64 pregnant cows. Isolates of fungi were obtained from cervix and vagina of 27.1% and 28.6% of treatment group, 26.7% and 31.2% of pregnant cows, and 33.3% and 21.4% of healthy non-pregnant cows, respectively, indicating no significant differences. It is showed that the cervix and vagina of the treatment group have been infected by six different mycotic isolates. However, the cervix and vagina of pregnant and non-pregnant healthy cows in control group were infected with 5, 6 and 5, 4 different fungal agents, respectively. Penicillium and yeast were the most common isolated agents. Regarding to the result of this study, it is concluded that fungal infections can occur in cervicovaginal cavity of Holstein dairy cows with or without reproductive diseases.
奶牛生殖系统的真菌感染尚未受到足够的关注。本研究的目的是确定患有生殖系统疾病或健康的荷斯坦奶牛的真菌感染情况。使用双棒拭子采集176头荷斯坦奶牛子宫颈阴道分泌物中的真菌分离株，其中子宫颈用双棒拭子，阴道分泌物用无菌棉拭子。对这些样本进行真菌感染评估。治疗组包括70头患有生殖疾病的奶牛，如流产、屡配不孕、子宫内膜炎、子宫炎、胎膜滞留、难产、宫颈炎和阴道炎。对照组包括42头健康未孕奶牛和64头怀孕奶牛。治疗组子宫颈和阴道的真菌分离率分别为27.1%和28.6%，怀孕奶牛分别为26.7%和31.2%，健康未孕奶牛分别为33.3%和21.4%，表明差异不显著。结果显示，治疗组的子宫颈和阴道感染了六种不同的真菌分离株。然而，对照组中怀孕和未孕健康奶牛的子宫颈和阴道分别感染了5种和6种、5种和4种不同的真菌病原体。青霉和酵母菌是最常见的分离病原体。根据本研究结果，得出结论：无论是否患有生殖疾病，荷斯坦奶牛的子宫颈阴道腔都可能发生真菌感染。
