Sažetak

Kalifornija mastitis testom (CMT) ispitano je mleko uzorkovano od 6609 ovaca, odnosno iz 13 218 mamarnih kompleksa. Od 986 uzoraka mleka sa povećanim brojem somatskih ćelija u mleku iz 910 (92,3%) uzoraka izolovani su uzročnici mastitisa. Najčešći izolovani mikroorganizmi su: E. coli izolovana iz 189 (20,76%) uzoraka, Micrococcus sp. iz 186 (20,43%) uzoraka, Bacillus sp. iz 177 (19,45%), Staphylococcus aureus iz 172 (18,9%) uzorka i Proteus sp. iz 121 (13,29%) uzoraka mleka ovaca. Koagulaza negativne stafilokoke (CNS) izolovane su u mnogo manjem broju iz 25 (2,74%) uzoraka, Streptococcus sp. izolovan je iz 19 (2,08%) uzoraka, Pseudomonas sp. iz 14 (1,53%) uzoraka, hemolitične E. coli izolovane su iz svega 6 (0,65%) uzoraka, a Streptococcus agalactiae iz samo jednog uzorka. Od 25 izolata koagulaza negativnih stafilokoka kao Staphylococcus chromogenes identifikovano je 16 (64%) izolata, a kao Staphylococcus simulans 9 (36%) izolata. Osetljivost izolovanih uzročnika mastitisa na antimikrobne lekove ispitana je disk difuzionom metodom.
