Comparison of California Mastitis Test (CMT), Somatic Cell Counts (SCC) and bacteriological examinations for detection of camel (Camelus dromedarius) mastitis in Ethiopia.
A total of 956 quarter milk samples from 253 traditionally managed lactating camels were collected aseptically from Negele (Borena Region), Dire Dawa, and Gewane (Afar Region), Ethiopia, according to multi-stage sampling. The quarter milk samples were subjected to California Mastitis Test (CMT), Somatic Cell Counts (SCC) and bacteriological examinations. Five hundred and seventy one (59.7%) quarter milk samples had microorganisms. Of these, 428 (75.0%) had isolates that were identified as major pathogens (MAP) and 143 (25.0%) as minor pathogens (MIP). A positive correlation was found between CMT scores and bacteriological classes (MAP, MIP) (p-value = 0.00). Strong correlation (p-value = 0.00) between CMT scores and SCC was recorded. The differences among the median log SCC of bacteriological classes (MAP, MIP) were not significant (p-value = 0.24). Similarly, the application of the cut-off level of 2.5 x 10(5) ml(-1) indicated less agreement (p-value = 0.32) for bacteriological classes MAP and MIP.
