| Abstract | ||||
| Abacteriological survey for studying the prevalence and bacteria associated with subclinical mastitis was carried out in 10 sheep flocks at kafr El-sheikh Governorate .Atotal of 245 milk samples were collected aseptically from 202dairy ewes. The prevalence of subclinical mastitis was 24,1% in gland and 30,7%in dairy ewes .Coagulase negative strains (CNS) were the most prevalent bacteria representing 67.3% of the isolates ,Staphylococcus epidermidis 45.9%was the most prevalent species followed by Staphylococcus haemolyticus 7.1%, Staphylococcus xylosus 6.1%, Staphylococcus Simulans 6.1%, Staphylococcus Caprae 2%. Corynebacterium to be the second place in importance and representing 11.2% of the isolates, also Staphylococcus aureus 7.1%, Escherichia coli 5.1%, Streptococcus agalactiae 3%, Pseudomonas aeroginosa 1%, Pasteurella haemolytica 1%. The in vitro sensitivity pattern of the isolated organisms against 7 antibiotics was tested, Flumequine and Gentamycin gave the best results in inhibiting all the tested strains ,while Cloxacillin ,Neomycin and Oxytetracycline have moderate result but the most strains were resistant to penicillin .It is concluded that subclinical mastitis in dairy ewes is aserious problem in the surveyed area | ||||
