A longitudinal study was conducted in five randomly selected farms in Kelantan, Malaysia to determine the seasonal occurrence of cattle fascioliasis and its association with climatic factors. A total of 480 faecal samples were collected by a random purposive sampling method from July 2018 to June 2019. The faecal samples were examined for the presence of eggs using a formalin ether sedimentation technique. Meteorological data including temperature, humidity, rainfall, and pan evaporation were obtained from a local meteorological station. The overall prevalence of cattle fascioliasis in Kelantan was 45.8%. The prevalence was observed to be slightly higher during the wet season from August to December (50-58%) than during the dry season from January to June (30-45%). Meanwhile, the mean eggs per gram (EPG) were highest in June (191.1 ± 0.48) and lowest in October (77.62 ± 95.5). However, there were no significant differences in the mean of EPG between the monthly prevalence, tested using one-way ANOVA ( = 0.1828). A statistically significant association ( = 0.014) was observed between the disease and cattle breeds, with Charolais and Brahman showing lower odds of having the disease. There were significant moderate-to-strong positive correlations between cattle fascioliasis and rainfall (r = 0.666; = 0.018) and humidity (r = 0.808; = 0.001), as well as strong negative correlations with evaporation (r = -0.829; = 0.001). The results indicated that the higher prevalence of cattle fascioliasis in Kelantan was correlated with the climatic factors, which include higher rainfall and humidity and lower evaporation.
在马来西亚吉兰丹州随机选取的五个农场开展了一项纵向研究，以确定牛片形吸虫病的季节性发病情况及其与气候因素的关联。2018年7月至2019年6月期间，采用随机目的抽样法共采集了480份粪便样本。使用福尔马林乙醚沉淀技术检查粪便样本中是否存在虫卵。从当地气象站获取了包括温度、湿度、降雨量和蒸发皿蒸发量在内的气象数据。吉兰丹州牛片形吸虫病的总体患病率为45.8%。观察到8月至12月的雨季患病率（50%-58%）略高于1月至6月的旱季（30%-45%）。同时，每克粪便虫卵数（EPG）在6月最高（191.1±0.48），10月最低（77.62±95.5）。然而，使用单因素方差分析（P=0.1828）检验，各月患病率的EPG均值之间无显著差异。观察到该病与牛的品种之间存在统计学显著关联（P=0.014），夏洛来牛和婆罗门牛患病几率较低。牛片形吸虫病与降雨量（r=0.666；P=0.018）和湿度（r=0.808；P=0.001）之间存在显著的中度至强正相关，与蒸发量之间存在强负相关（r=-0.829；P=0.001）。结果表明，吉兰丹州牛片形吸虫病的较高患病率与气候因素相关，包括降雨量增加、湿度增加和蒸发量降低。
