| Abstract | ||||
| The pathology caused by gastro-intestinal parasites. is varied. Thus infection with Ostertagia spp is associated with morphological and functional destruction of the gastric glands of the abomasum. The primary pathology caused by Haemonchus contortus and Mecistocirrus digitatus is marked hemorrhage through wounds in the abomasal mucosa. Infections such as Trichostrongylus spp and Nematodirus spp cause villous atrophy and adults of Oesophagostomum spp and chabertia ovina in the large intestine cause ulceration and hemorrhage. These lesions have been described previously by Symons and Steel (1979), Dargie (1981) as well as Soulsby (1982). In Egypt Ezzat (1984) reported 6 species of nematode parasites in the alimentary tract of some calves and identified them as O.circuncinata, H.contortus, C. onchophora, C. punotata, Oesophagostomum, Venulosum and B. phlebotomum. Deleon and Juplo (1966) examined the guts of 60 buffaloes for the helminth parasites in philippines. They stated that 68% of the animals were infested by M.digitatus, Ostertagia sp. Oesophagostomum radiatum and H. palonlae, which were recorded for the first time in philippines. In a survey on the helminth parasites in 46 buffalo calves in 1971, Bhopale, et al. recovered 116 nema- tode species of which Oesophagostomum sp. were the most prevalent one with an infestation rate of 56.1% Tongson and Caspe (1975) and Tongson, et al., (1976) found that the most common species of nematodes among cattle in two localities in philippine were; Cooperia, Bunostomum, Mecistocirrus, Oesophagostomum, Trichostrongylus, Haemonchus and Strongyloides. In 1978, Horak as well as Horak and Louw observed that Haemonchus spp, were the most abundant nematodes among the South African cattle. Bejsovac and Doriat (1982) found that only 96 from 950 examined cattle were infested with Trichocephalus (3.9%), Cooperia (2.4%), Ostertagia (0.6%), Chabertia (0.4%), Nematodirus (0.3%), Capillaria(0.2%), Oesophagostomum (0.2%), Bunostomum (0.1%) and Trichostrongylus (0.1%). Moharam (1987) in Kalubia and Sharkia found that the nematodes were 0. ostertagi, O. trifurcata (17.9%), Τ. απεί (10.4%), Marshallagia marshalli (3.0%), Toxocara. vitulorum (22.4%), T. colubriformis (18.4%), C. mecmasteri (20%), B. phlebotomum (2.3%) and Oesophagostomum venilовит (7.7%). The aim of the present task is to spot light on the intensity of infection with the different nematode species could be encountered from the alimentary tract of Egyptian cattle. | ||||
