Abstract   

A total number of sixty apparently healthy camels were investigated for the presence of nasal microflora. Fifty of these camels were presented for slaughter at Al-Ahsa slaughter house (group A), the remaining ten camels were the herd belonging to the Camel Research Unit and kept at the University Farm (group B). During six months, a total of one hundred and ten nasal swabs were collected and examined for bacterial isolation and identification. The type of microorganisms recovered included Staphaylococcus aureus (89. 1 %) of the total isolates, Escherichia coli (5.0%), Streptococcus spp. (2.5%), Kiebsiella spp (1.7%) and Corynebacterium spp (1.7%). The predominant and significant bacteria, Staphylococcus aureus and Sfreptococcus spp. isolates were subjected to antibiotic sensitivity test and found sensitive against the examined antibiotics by various degrees.
