Prevalence and burden of gastrointestinal helminthes among local chickens, in northern Jordan.
We conducted a cross-sectional study from December 2004 to February 2005 and from June 2005 to August 2005. The study aimed to determine the prevalence of gastrointestinal and tracheal helminthes among local chickens in northern Jordan. A total of 208 male and female local scavenging chickens were selected randomly. We examined the trachea and gastrointestinal tract of each bird for the presence of helminthes. We recovered three nematode and eight cestode species. No trematodes were found. One hundred and fifty-two birds (73.1%) (95% CI: 67, 79) were infected. The prevalences of different species were as follows: Ascaridia galli female 28%, male 43%; Capillaria obsignata 0.5%; Heterakis gallinarum 33%; Amoebotaenia cuneata 4.3%; Choanotaenia infundibulum female 23%, male 13%; Davainea proglottina 1.4%; Hymenolepsis cantaniana 11%; Hymenolepsis carioca female 35%, male 24%; Raillietina cesticillius female 5%, male 11%; Raillietina echinobothrida 16%; and Raillietina tetragona 18%. The prevalences of A. galli and R. cesticillus were higher in male than female hosts while those of C. infundibulum and H. carioca were higher in females. The median worm burden was 7 (range 0-168) worms per chicken.
