Records from 898 cases of bovine mycotic abortion occurring over the five years 1969 to 1974 in South Wales were examined with particular reference to incidence and climate. Mean incidence was lowest in September and highest in January and February. Annual incidence of Aspergillus-type infection decreased but that of Mucortype did not alter significantly. Most abortions occurred during the last trimester of pregnancy. The abortion rate for cattle fed hay in cowsheds was extremely high compared with that for other management systems. No correlation could be detected between total rainfall or number of raindays in June and September and mycotic abortions occurring over the succeeding 12 months. Fungal abortion was followed by pregnancy in most cases where subsequent breeding performance was known.
对1969年至1974年这五年间发生在南威尔士的898例牛霉菌性流产病例记录进行了检查，特别关注发病率和气候情况。平均发病率在9月最低，1月和2月最高。曲霉菌型感染的年发病率下降，但毛霉菌型的发病率没有显著变化。大多数流产发生在妊娠晚期。与其他饲养管理系统相比，在牛舍中喂干草的母牛流产率极高。6月和9月的总降雨量或降雨天数与随后12个月内发生的霉菌性流产之间未发现相关性。在大多数已知后续繁殖性能的病例中，霉菌性流产后会再次怀孕。
