Abstract
Lungworm infection among sheep was studied in different localities of the North coast of Egypt, to investigate the prevalence of infection in that area. As well as to determine the most effective method for diagnosis of the disease in sheep. in this study a trial for comparative diagnostic methods such as post-mortum examination, faecal and serological diagnosis were evaluated. Also, -a comparative study for evaluation of both ELISA and Immunoblot using two types of antigens, adult worm and larval antigens of Dfilaria.
A total number of 1300 animals of Barky sheep were used in this study. From these animals, faecal samples were collected and examined using Baermann technique for demonstration of first-stage larvae of lungworms. Also 101 animals slaughtered at Matrouh abattoir, from these animals blood samples, lungs, and intestinal contents were examined.
The results of these studies revealed that:The
incidence of lungworm infection among sheep in the North coast of Egypt was found to be 26.77%.
The seasonal incidence among sheep was found to be 42.77%, 19.09%, j.i’’ summer, and autumn respectivily. Regarding the relationship between age of animals and rate ol inecUon, the incidence was found to be 11.17%, 26.83%, and 40.41% among lambs of about 6 months old, yearlings of about 1-2 years old, and older sheep over 2 years old respectivily.
