ABSTRACT
This study was carried out to identify the causative agents of different types of mastitis in Tamboul area. Sixty one milk samples from a field survey positive for change of colour using California mastitis test (CMT) were obtained from 10 herds comprising 1649 camels during 3 seasons (summer, winter and autumn) of same year. In the slaughter house investigation, 37 tissue samples and swabs obtained from different udder pathological lesions of 353 mastitis cases out of 2158 female camels of Arabi breed were tested by conventional bacteriological methods. The results revealed 98 isolates which consisted of 85 Gram-positive (86.73%) and 13 Gram-negative ones (13.27%). The isolates in order of frequency were Staphylococcus spp. (46.94%), Streptococcus spp. (18.37%), Bacillus spp. (13.27%), Micrococcus spp. (4.08%) and Corynebacterium spp. (4.08%). The Gram-negative bacteria isolates were Escherichia coli (8.16%), Pseudomonas spp. (4.0%) and Salmonella typhimurium (1.02%).
