Abstract
Four bacterial species, namely Serratia liquefaciens, Stenotrophomonas maltophilia, Klebsiella ornithinołyrica and Aeromonas hydrophila were isolated from Hyalomma (hyalomma) dromedarii, and five species, namely: Rahnella aquatilis, Pseudomonas fluorescens, Enterobacter cloacae, Chryseomonas luteola and Chryseobacterium meningosepticum from Argas (Persicargas) persicus organs and haemolymph. Isolated bacteria were identified using the Analytical Profile Index 20E. The disk diffusion test was carried out on isolated bacteria to determine their antibiotic sensitivity. All bacteria from H. dromedarii were found to be sensitive to chloramphenicol amoxicillin/clavulanic acid, neomycin, streptomycin, tetracycline and nitrofurantoin, whilst bacteria isolated from A. persicus, were found to be completely sensitive to tetracycline and mostly sensitive to chloramphenicol and triplesulpher. Appropriate antibiotics should be concurrently administered to hosts during tick control procedures.
