Abstract: A field survey for the study of bacterial diseases of the reproductive system of camels in Eastern Sudan was conducted .The important diseases of she-camels were acute catarrhal endometritis, pyometra, chronic endometritis and acute or chronic mastitis. The incidence of these diseases increased with age and reached its peak in autumn. Isolated bacteria included Staphylococcus aureus, E. coli, Klebsiella spp., Corynebacterium spp., Proteus spp., Salmonella spp. and Streptococcus spp. Although trials to isolate Brucella spp., were negative, high agglutinating titres were detected. Male camels had orchitis which was due to Staphylococcus aureus, E. coli and Proteus spp. These organisms in addition to Corynebacterium spp. and Clostridium spp., were isolated from wounds of the external genitalia. Incidence of orchitis and wounds of external genitalia was also increased with age in autumn.
