| Abstract: |
In the present study a trial was made to exarnme anaerobically different samples ’of ’diseased ’as well asapparently normal (120) chickens, (120) ducks, (120) geese and (120) turkeys at one-day-old and 45-days-old toinvestigate the clostridial microorganism. , There are variation in the prevalence rate of clostridiumspecies isolated from apparently chickens at age one - day - old &45 - days- old which lower ( 46.7% ,60% respectively) than that of” diseased chickens ( 70 % ,93.3% respectively). Mean while the rate of clostridial species isolated from 30 liver, 30intestine, 30 kidney and 30 spleen of apparently normal chickensat age one-day-old were (23.30/0,400/0, 3.30/0, 0% respectively)which lower than that of diseased chickens ( 30%, 66.7%, 23.30/0,6.7% respectively ), but at age 45 -days-old the isolation fromliver, intestine, kidney and spleen of apparently normal chickenswere (300/0, 46.70/0, 3.30/0, 3.30/0 respectively) which lower thanthat of diseased chickens ( 500/0, 800/0, 23.3%, 13.3 0/0respectively). Among apparently normal and diseased chickensat age one-day-old and 45- days-old examined found thatC. perfringens was the most predominant species then C. sporogenes, then C. sordellii and C. tertium. Also foundconjunction of C. perfringens plus C. sordellii and C. sordelliiplus C. sporogenes at age one-day old but at age 45-days- old found C. perfringens plus C. sordellii, C. perfringenes plus C. tertium and C. perfringens plus C. sporogenes. Ontyping of C. perfringens isolated from the examined chickens and from different organs type ”A” was the most prevalent followed by type ”D” then type ”C” In the mean time type ”A”and ”D” was isolated only from apparently normal chickenswhile type ”C” isolated from diseased chickens.
