This work was carried out to investigate the parasitological and bacter iological causes of respiratory diseases in camels, as well as, the drug of choise used for treatment in both. The blood parameters revealed leucocytosis in both the parasitic and bacterial types, with significant eosinophilia in the former case and significant neutrophilia in the latter. The biochemical analysis showed significant lowered calcium in serum of the bacterial infection, while serum total proteins, albumin and globulin, iron and blood glucose levels significantly dropped in both bacterial and verminous causes. On the other hand, serum enzyme activities exhibited high values in both affections. On isolation, the most prevalent causes were Staph. aureus, Staph. citrus, Strept. zoo-epidemicus and Pseud. areugenosa. as microorganisms, while Dicty caulus larvae as a parasitic causes.
Citarine and Terramycin 100 were used for treatment of verminous and bacterial affections, respectively.
