RESUMEN
Musculature samples of oesophagus, heart, diaphragm, tongue, masseter and skeletal muscles from each of 52 horses and 130 donkeys were microscopically examined by both, compressorium and trypsin digestion techniques for detection of Sarcocystis infection. The infection rate reached 88.5% in horses and 91.5% in donkeys. The sarcocysts were detected in all examined samples with the highest rate in oesophagus [100%]. The morphology and size of the detected sarcocysts, metrocytes and bradyzoites in both, horses and donkeys were found to be similar. The cyst wall was thick [> 2 microm] and appeared striated. Experimentally infected dogs with horse or donkey meat excreted sporocysts measuring 12.2 - 14.6 X 9.0 - 10.7 microm and 12.0 - 14.9 X 8.3 - 10.7 microm. respectively. The prepatent period was 10 - 14 days. It was concluded that Sarcocystis infecting both, horses and donkeys in Egypt could belong to the same species [Sarcocystis bertrami]

A total of 192 randomly collected sheep sera were tested serologically by indirect hemagglutination test [IHAT] for diagnosis of H. contortus. The sensitivity of the test was 87.5%. The most antigenicfraction obtained from adult worms extract was used as a specific antigen. The highest percentage of seropositive samples [26.79%] was detected at titers of 1/128. Incidence of H. contortus in seropositive samples at various titers was also estimated

140 buffalo-calves [up to 2 months old] samples [faecal and its corresponding blood samples] were examined coprologically and serologically [using indirect haemagglutination test, IHAT]. It was found that the infestation rate of Toxocara vitulorum after coprological examination reached 57.14% compared with 71.43% that detected by passive haemagglutination test
