Studies on sarcocystosis showed an overall sero-prevalence of 79.46% by IFAT which included 80.14% in cattle and 78.59% in buffaloes out of 716 animals screened. The antibody titers of six randomly selected positive samples from different age groups of <2, 2-5, 5-10 and >10 years old bovines ranged from 16 to 64, 32 to 256, 32 to 128 and 16 to 64 with an average titer of 32 ± 2.92, 106.6 ± 34, 74.6 ± 17 and 34.6 ± 9, respectively. Significantly, lower rates of infection were observed in the cattle of below 2 years (60%) age and an ascending rate of infection in the age groups of 2-5 years (81.33%), 5-10 years (80.52%) and above 10 years (90.9%).
对肉孢子虫病的研究表明，通过间接荧光抗体试验（IFAT）检测，总体血清阳性率为79.46%，在筛查的716只动物中，牛的血清阳性率为80.14%，水牛为78.59%。从年龄小于2岁、2 - 5岁、5 - 10岁和大于10岁的不同年龄组中随机选取的6份阳性牛样本的抗体滴度分别为16至64、32至256、32至128和16至64，平均滴度分别为32±2.92、106.6±34、74.6±17和34.6±9。值得注意的是，2岁以下牛的感染率较低（60%），而2 - 5岁（81.33%）、5 - 10岁（80.52%）和10岁以上（90.9%）年龄组的感染率呈上升趋势。
