Abstract

The primary objective of this study was to establish data on mastitis in Awassi Sheep in Al-Balqa Province of Jordan. Milk samples were collected from 260 lactating ewes that selected randomly from eight flocks. California Mastitis Test (CMT) gave result with 220 milk samples; 122 samples (55.5%) showed positive CMT. Infection with some bacterial species was associated with positive CMT. About 26% of the ewes revealed clinical signs of mastitis. The highest percentage of bacterial count, which range from 3×102 to <3.0 103 cfu mL-1 was founded in the milk samples. The most predominant bacteria isolated were Staphylococcus aureus, Streptococcus agalactiae, Streptococcus spp., Escherichia coli, Corynebacterium spp. and Coagulase negative Staphylococci. Sensitivity tests were applied to different isolated strains., Gentamycim, Ampicillin and Tetracycline were the most effective antimicrobial agents against the bacterial isolates.
