Abstract

Camel milk samples were randomly and aseptically collected after discarding first milk streak from 243 quarters of milking camels without clinical sign of mastitis or bacteriological investigation. There was no bacterial isolation in 61.73% samples. The bacteria isolated in remaining samples were Staphylococci (n=78; coagulase negative Staphylococci: 71 and Staph, aureus: 7) and Streptococci (n=26). Five new species of coagulase negative Staphylococci including Staph, saprophytics, Staph, delphini, Staph, capitis, Staph, chromogenes and Staph, caseolyticus were identified. PFGE analysis carried out on 7 isolates of Staph, aureus and produced 2 distinct pulsotypes designated as pulsotypes A and B. All Staph, aureus isolates were found to be included into 2 spa types: t527 and tl532. Coagulase negative staphylococci were the main bacteria isolates (55.04%) and the frequency of Staph, aureus with 2 spa types was considered as 5.43% of total bacterial isolation. © 2017 Camel Publishing House.
