“…In Bangalore, India (Puttalakshmamma et al 2008) found (91.4 %) prevalence A. galli in chickens. Higher prevalence (88 %) of A. galli was also reported in free range system in Germany (Kaufmann et al 2011) and in Ethiopia (71.6 %) (Abede et al 1997).…”

Rural poultry production in Bangladesh is mainly based on the free range or backyard poultry production system. This backyard poultry plays a vital tool for poverty alleviation as well as for empowerment of poor women of this country. However, this production system has disadvantage of susceptibility to many diseases including higher burden of parasitic infection. Therefore this cross sectional epidemiological investigation was done to determine the prevalence and distribution of gastrointestinal helminths in Narsingdi district, Bangladesh. To conduct this study a total of 150 chickens from three different villages of Narsingdi district, Bangladesh (50 chickens per village) were collected by random sampling method and killed by cervical disarticulation. Thereafter, all the chickens were necropsied and gastrointestinal tracts were examined macroscopically for the presence helminth infection. In total two nematode (Ascaridia galli, Heterakis gallinarum,) and one cestode (Raillietina spp.) were identified by post mortem examination. Raillietina spp. was detected as the most prevalent helminth species (86-92 %) followed by A. galli (70-86 %), and H. gallinarum (70-76 %) in studied villages. In some chickens petechial hemorrhage were observed in the small intestinal wall which was associated with the A. galli infection and for some birds white tiny nodules were detected in case of H. gallinarum infection. No significant difference in parasite prevalence was observed between male and female bird as well as among three studied villages (P [ 0.05). We observed that most of chickens were infected with more than one species of parasites. This finding suggests that the poultry production system in rural areas of Bangladesh and the environmental conditions are very favourable for the transmission and persistence of the parasite species in rural areas of Bangladesh.

“…were the most commonly detected helminths in organic layer production, while prevalence figures in hens in conventional cages were lower (Permin et al 1999 (Kaufmann et al 2011). A study of infection dynamics of A. galli in laying hens in both organic and conventional farms in Sweden discovered that all flocks became infected following the arrival of the birds with infective eggs presented in the environment (Höglund and Jansson 2011).…”

“…Drooping wings, decrease egg production (Ackert and Herrick, 1928). These symptoms are more common in those chickens when their age is about 3 months (Kaufmann et al, 2011). The worm can be directly identified by post mortem diagnosis method (Soulsby, 1982) or by the examination of faecal samples or by cutting of intestine "post mortem" (Taylor et al, 2007).…”

| This study was conducted from September 2013 to march 2014 to find out the prevalence of A. galli in some poultry farms of district Mardan. During this period total of about 751 chicken intestines were collected and examined for the presence of A. galli. In these 751 about 161 were infected and the overall prevalence rate of A. galli was about 21.44%. In this study total 360 local chicken were examined in which 90(25%) were infected. 221 layer chicken were examined in which 41(18.55%) were infected and about 170 broiler of which 30(17.64%) were infected. The overall study show that A. galli is the most common and highly prevalent nematode in the chicken of district Mardan. The study also shows that A. galli is common health problem in both free ranging and poultry chicken so suggest the need of proper poultry management.
