Gram-negative bacteria from the camel tick hyalomma dromedarii [ixodidae] and the chicken tick argas persicus [argasidae] and their antibiotic senstivities

ABSTRACT

A total of nine species of gram-negative bacteria were isolated from organs and haemolymph of the hard tick Hyalomma [hyalomma] dromedarii and the soft tick Argas [persicargas] persicus. Four species; namely, Serratia liquefaciens, Stenotrophomonas maltophilia, Klebsiella ornithinolytica and Aeromonas hydrophila were isolated from H. dromedarii and five species; namely, Rahnella aquatilis, Pseudomonas fluorescens, Enterobacter cloacae, Chryseomonas luteola and Chryseobacterium meningosepticum were isolated from A. persicus. Isolated bacteria were identified using the analytical profile index 20E. Disk diffusion test was carried out on all isolated bacteria to determine antibiotic sensitivity of chloramphenicol, amoxicillin/clavulanic acid, neomycin, streptomycin, triplesulphur tetracycline and nitrofurantoin. The results were discussed
