| Abstract | ||
| Out of 308 samples 205 from apparently healthy and 103 diseased lungs of slaughtered camels. The total number of positive samples was 203 (65.91%) from which 124 (60.49%) from apparently healthy and 79(76.70%) from pneumonic lungs of camels. The total number of isolates was 302 isolates from which 174 isolates from apparently healthy and 128 isolates from pneumonic lung of camels. The total number of Gram positive bacterial isolates was 132 (43.71%) from which the incidence of Gram +ve isolates was 80 (45.98%) and 52 (40.63%) in apparently healthy and diseased lungs respectively as shown in table (3). The most prevalent single Gram positive isolates from lungs of slaughtered camels were non haemolytic streptococci 17 samples (16.35%) followed by Staphylococcus aureus 12 samples (11.54%), Micococcus spp. 6 samples (5.77%) , Arcanobacterium pyogenes 3samples (2.89%) , Diplococccus pneumoniae 2 samples (1.92%). Regarding to the pathogenicity of some bacterial isolates in experimentally infected mice by 0.1 ml (3 x 108 CFU. ml) I/P. It was resulting in death to mice varying from (40, 60, to 100%) as pathogenicity of Staphylococcus aureus, Micrococcus spp and Arcanobacterium pyogenes respectively. The most effective antimicrobial agents against some selected isolates obtained from lungs of camels were Cloxacillin, Gentamicin and Norfloxacin against Arcanobacterium pyogenes. Ciprofloxacin, Gentamicin and Norfloxacin against, Micrococcus spp., non haemolytic streptococci and Staphycoccus aureus. | ||
