Seven hundred and sixty-three camels from 400 herds of local Sudanese camel breeds were investigated for the prevalence of mastitis, identification of its bacterial causes and determination of the leucocyte contents of camel's milk. One hundred and forty-nine (19.5 per cent) of the 763 camels examined were diagnosed as mastitis cases based on clinical signs. One hundred and fifty-nine (47.3 per cent) of the 336 randomly selected milk samples were reactive in a rapid mastitis test and 16 of the 153 tested samples contained Brucella abortus agglutinating antibodies. Streptococcus, Staphylococcus, Micrococcus and Aerobacter species and Escherichia coli were found to be the main causes of mastitis (in descending order). The leucocyte contents of the 757 milk samples ranged from <5 X 10(5) to >7.5 X 10(6) leucocyte ml-1 and 42.8 per cent of the samples contained <5 X 10(5) cells ml-1. Neither significant correlation between the leucocyte content of milk and isolated bacterial species nor significant variation in leucocyte contents during different stages of lactation were detected.
