Abstract
This study was done for the detection of capsulated Staphylococcus aureus strains which isolated from bovine & buffaloes Mastitis . 23 ( 57.5 %) & 8 ( 53 %) strains of these bacteria were isolated , 6 (26 %) & 2 (13.3 %) were capsule producing strains, and that 9 ( 39.1 %) & 4 (26.6 %) were slime producing strains, as well as an increase in number of capsules and slim producing strains were observed following growing of these bacteria in culture media containing glucose, milk. The experimentally histo- pathological study revealed presence of capsules in lung sections stained with Hematoxylin – Eosin as a halo area which appears around the bacterial cells . In edittion to a strong positive reaction with periodic acid shiffs.
