Summary

	This study was perfor med during winter 2002 in a sheep flick manifesting respoatory embarrassments in 44 out of 321 animals of different ages and sex. Bacteriological examination of nasopharyngeal swabs taken from diseased sheep reveaded the detection of Haemophilus somnus (H.somnus) ether alone (55.6 %) or in combiation with sterplococcus pnumaniae (22.2% ).

	klebsiella pneumoniae (11.1%). and staophylococcus. Aureus (11.1%). Also H. somnus was detected from the nasopharyngeal swabs coltected from in contact apparenlty healthy cattle. Electroporetic pattern of Haemophilus somnus isolated from diseased sheep and incontact clinically normal cattle proved the simitaity ovine and bovine strains.

	Such criteria have potential value for epidemiological studies of hemophilosis among from animals. Clinical signs exhibited on the diseased animals was described and some epodemiological data and the treatment of diseased animals was studied and discussed.
