The bacteriological examination of 40 swabs from the nasal discharges of 20 local and 20 imported camels revealed that, 37 of them gave 47 bacterial isolates, out of them (25.53%) were Gram-positive and the others were Gram negative. The most important identified bacterial spp. were Staphylococcus aureus (21.27%) Staphylococcus epidermidis (4.25%), Pseudomonase aeruginosa (4.25%) and E. coli (38.29%). The examination of 40 faecal swabs from 20 local and 20 imported diarrhetic camels revealed isolation of 50 bacterial isolates, all of them were Gram-negative. The most important isolates were, Salmonella spp. (4%), E.coli (42%), Citrobacter spp.(24%) and Klebseilla spp. (12%). The prevalence of antibodies to brucella was studied serologically among 126 camels (95 local and 3] imported) using 3 different serological methods, namely, RBPT, STAT and ELISA. For local camels, the prevalence rate was 9.47%, 5.26% and 9.47%, respectively In males the rate was higher than in females except by the STAT. Regarding imported camels, the prevalence rate was 6.67%, 9.67% and 25.80% using the same - tests respectively. Also, in males the rate was higher than in females except by ELISA.
