Abstract<\/strong><\/p>\n

This research was conducted to determine bacterial etiology, epidemiological and clinical features of clinical mastitis cases in Syrian, using Awassi ewes aged 2-6 years, which is hold for both milk and meat production. The research was done during the last twenty years (from 1993 to 2012) at Jedrine Research Station, General Commission for Scientific Agricultural Research (GCSAR), Hama, Syria. 75 milk samples was collected from clinical infected ewes in different times, and subjected to the bacteriological analysis and sensitive reactions. The percentage of clinical mastitis was 6.05% (261 out of 4247). There were a significant difference (p\u22640.01) in terms of the percentage of infection by the three types of mastitis, the percentages were as follow: Acute (76.6%), gangrenous (18.8%), and chronic (4.6%). The percentage of the mastitis that was most often registered in one half was (73.94%), while in two halves the percentage was (26.05%). Most of the mastitis\u00a0occurred during first two months after lambing (74%), the rest (26%) was after weaning of lambs. Chi-square test\u00a0showed significant differences (p\u22640.01)\u00a0<\/strong>in the frequency\u00a0of\u00a0mastitis\u00a0cases within different months after parturition, and in lactation seasons.\u00a0In terms of frequency\u00a0of\u00a0mastitis\u00a0cases the highest frequency was in the third production season (27.97%), where the ewes suffered more from clinical mastitis (p\u22640.01), then the second production season (26.05%),\u00a0<\/strong>and the lowest was the first production season (10.72%). Using hypothesis test to estimate the difference between two groups, Z value (Z=0.47) was within the normal range (\u00b11.96), so there was no significant difference in the occurrence of mastitis between manual stripping\u00a0and machine lactation. The results of bacterial analysis for 75 milk samples showed a bacterial growth in 62 samples (82.66%).\u00a0The most prevalent isolated bacteria were staphylococcus<\/em>\u00a0aureus\u00a0<\/em>(32.85%),\u00a0Pasteurella<\/em>\u00a0hymolytica<\/em>(18.57%),\u00a0E.coli<\/em>(14.3%),
\n\u200e<\/u>Klebsiella<\/em>\u00a0(11.4%),\u00a0Actinomyces<\/em>\u00a0pyoges<\/em>\u00a0(10%), Stretococcus<\/em> lactis<\/em> (7.14%), and Bacillus<\/em>\u00a0subtilis<\/em>\u00a0(5.71%). The percentage of the ewes that recovered after the treatment by different antibiotics was 71.26%.\u00a0Enroflouxacine\u00a0showed high effectiveness for most isolated bacterial\u00a0strains, followed by\u00a0Gentamicin\u00a0, \u00a0then\u00a0Norfloxacin,\u00a0Oxytetracycline\u00a0, Ampicillin, Sulfa compounds, and lastly Neomycin. Most bacterial strains were resistant to Penicillin and\u00a0Erythromycine. The Staphylococcus<\/em>\u00a0aureus<\/em>\u00a0was more sensitive to antibiotics, while the Actinobacillus<\/em> pyogenes<\/em>\u00a0was more resistant, this ensure the necessity of the intensification of sanitary control for protection and prevention of mastitis especially during first two months after lambing, and in multi-partied ewes, and the treatment of the infected ewes with efficient antibiotics according to sensitivity tests, in addition to the improvement of environmental conditions in breeding stations for Awassi ewes.<\/p>\n
