    تمت دراسة 194 عزلة من المكورات العنقودية عزلت اعتبارا من عينات حليب مأخوذة من قطعان مختلفة من الأبقار اللبونة مصابة بالتهاب الضرع الجرثومي في محافظة اللاذقية .

    A total of 194 isolates of staphylococci were isolated from milk samples collected from different herds of dairy cows infected with mastitis in Lattakia- Syria. Of these194 isolates, 66(44,30%) isolates were identified as Staphylococcus aureus and 83(55,70%) as coagulase-negative staphylococci (CoNS) consisted of the species: Staphylococcus epidermides, Staphylococcus saprophyticus, Staphylococcus xylosus, Staphylococcus simulans.In addition to staphylococci count in milk samples, the total count of bacteria was performed too. All these staphylococcal isolates were tested for antibiotic sensetivity by agar dilution method outlined by the National Committee for Clinical Laboratory Standard (NCCLS) and the minimum inhibitory concentrations (MICs) were determined for ten antibiotics. The antibiotics tested and MIC90 values (as µg/ml) for Staphylococcus aureus isolates were: pencillin 0.3,ampicillin 0.17,oxacillin 0.5,gentamicin 3.5,cephalothin 1,erythromycin 0.75,clindamycin 1, pirlimycin 1.25, neomycin 2, and lincomycin 16.These values were for CoNS isolates as follows:0.25, 0.15, 0.5, 3.5, 0.75, 0.75,0.25, 0.5, 1.5, and 15 respectively. Depending on the resulting MICS values, the isolates were divided into three catidories sensitive, intemediate sensitive, and resistant. The percent of resistant isolates of Staphylococcus aureus versus CoNS ones were as follows: pencillin (46.97 vs 79.52),ampicillin (62.12 vs 50.56),oxacillin (7.57 vs 9.63), erythromycin (21.21 vs 12.05),clindamycin (30.30 vs 13.25), pirlimycin (34.58 vs 51.18), neomycin (36.36 vs 48.19), and lincomycin (19.70 vs 13.25) No resistance was detected for gentamicin, and cephalothin for all isolates.

    The research is divided in two parts. In the first part , performed the isolation and classification of staphylococcus were carried out.In the second part , we tested the susceptibility of used antibiotics against bacterial isolates and role of application of tested antibiotics to achieving the clinical healing. 119 isolates of staphylococcus were obtained from injured poultry wounds , from died birds organs and from poultry farms environment located in The Syrian Coast. The staphylococcus sorts distributed as following : 70 Isolates were S.aureus,19 S.epidermides,8 S.intermedius,12 S.lentus,8 S.xylosus,2 S.capitis, with proportion 58,88%,15,96%,6,72%,10%,6,72%,1,68% respectively. The distribution of clinical infection of birds flocks related with number increasing of Staphylococcus in studied poultry farms air.
