Result and discussion. 
As a result of the conducted research, 18 types of nematodes were 
recorded among sheep in different regions of the Republic of Karakalpakstan. 
During the study, 15 types of nematodes from 18 types were recorded in sheep 
(
Trichocephalus ovis, Chabertia ovina, Oesophagostomum columbianum, Oesophagostomum 
venulosum, Trichostrongylus axei, Trichostrongylus vitrinus, Haemonchus contortus, Haemonchus 
placei, Marshallagia marshali, Nematodirus abnormalis, Nematodirus helvetianus, Nematodirus 
oiratianus, Dictyocaulus filarial, Skrjabinema ovis, Skrjabinodera sagia
) are geohelminths, and 
only 3 species (
Gongylonema pulchurum, Parabronema skrjabini, Setaria labiato-papillosa
) are 
biohelminths. 
According to the research results, nematodes live in the host’s digestive system, mainly in 
the stomach and small intestines (10), large intestine (4), trachea and bronchi (1), muscle tissue (1), 
esophageal epithelium (1), and abdominal cavity (1), found to be parasitic. 
The results of research on the level of infection of sheep with helminths - nematodes - 
Trichocephalus ovis (11.3%), Chabertia ovina (13.2%), Oesophagostomum columbianum (26.4%), 
Oesophagostomum venulosum (17%), Trichostrongylus axei (35.9%), Trichostrongylus vitrinus 
(28.3%), Haemonchus contortus (32.1%), Haemonchus placei (17%), Marshallagia marshali 
(15.1%), Nematodirus abnormalis (28.3%), Nematodirus helvetianus (24.5%), Nematodirus 
oiratianus (20.7%), Dictyocaulus filaria (20.7%), Skrjabinema ovis (5.6%), Gongylonema 
pulchrum (5.6%), Parabronema skrjabini (9.4%), Skrjabinodera sagia (7.5%), Setaria labiato-
papillosa (11.3%).
