Abstract

milking she-camels reared in desert of Daraw and Shalateen cities (South Egypt) using California Mastitis Test
(CMT) in association with conventional bacteriological examinations of their milk, was aimed in the present study.
A total of 210 she-camels were examined and tested by CMT. The positive cases were sampled and
bacteriologically analyzed. The obtained results concluded that CMT is a beneficial screening tool for detection of
subclinical mastitis of she-camels. Bacteriological examinations supported the results of the screening CMT in
milking she-camels. The prevalence of subclinical mastitis of the examined she-camels in Daraw and Shalateen
was 25.69 % and 16.31 % respectively. The prevalence of subclinical mastitis is increased by increasing the age of
she-camels. The most common mastitis pathogens isolated from milk of CMT positive she-camels were belonging
to Gram positive bacteria rather than negative. Coagulase Negative one staphylococci was the predominate agent
followed by E. coli, Staphylococcus aureus and Streptococcus agalactiae
