“…The larvae can destroy the intestinal epithelium and necrosis of the mucosal layer. Heavy infection with adult worm can cause obstruction of the small intestine and death (Ackert and Herrick 1928;Ikeme 1971;Tugwell and Ackert 1952). A. galli may also transmits other infection such as Salmonella in chicken (Chadfield et al 2001;Eigaard et al 2006) and concurrent infection of A. galli with other pathogens produce more severe pathological condition than the single infection with this pathogen alone (Dahl et al 2002).…”

“…This parasite is normally reside in the small intestine of chickens and is considered to be responsible for the substantial economic losses due to decrease in feed conversion, weight loss, reduced egg production and associated treatment cost (Ackert and Herrick 1928;Danicke et al 2009;Phiri et al 2007). Both the larval stage of the parasite and the adult worm are liable for the pathological consequences.…”

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.

“…He proposed that the retarded development could be due to density-dependent worm to worm interactions or could be related to host immunity. Ackert & Herrick (1928) postulated that immunity against A. lineata infections did not develop until 3 months of age. ' Herd & McNaught (1975) found a greater antigenic stimulation and immune reaction in chickens following exposure to a greater numbers of worms.…”

Studies onAscaridia galliin chickens kept at different stocking rates

et al. 1998

The development of Ascaridia galli infections was investigated over a period of 378 days in parasite naïve chicken flocks ('permanent flocks') kept at different stocking rates and infected by introducing previously infected chickens (seeder birds). The results of this study indicated that differences in stocking rate may lead to different levels of establishment of A. galli infections in chickens. Furthermore, significantly higher weight gains were seen in the medium stocking rate (MSR) group than in either the low stocking rate (LSR) or the high stocking rate (HSR) groups. Periodically, the egg excretion was significantly different between the groups. Although not significant for the whole period, the general trend was that the egg excretion was lower in the MSR group than the LSR and HSR groups. The mean worm burdens in the permanent flocks at the end of the experiment were not significantly different from each other. To estimate the availability of infective eggs in the houses and pens, tracer animals were introduced into each of the permanent flocks every month. Information derived from tracer animals did not confirm an effect of stocking rate on the availability of infective eggs in the environment, although there was a trend towards higher mean worm burdens in the tracers from the MSR group.

“…A. galli specially restricted to small intestine of bird (Yamaguti, 1961) such as chicken, turkey, geese, guinea, fowl and wild bird in most part of the world (Ackert, 1931;Kates and Colglazier, 1970;Soulsby, 1982;Anderson, 1992).The principle host being the chicken (Ackert, 1931;Kates and Colglazier, 1970). A. galli infection cause loss of weight, anorexia, hemorrhages in the intestinal mucosa, obstruction of the intestinal lumen (Ackert, 1931;Ikeme, 1971) reduction in growth retardation, reduced feed production rate, loss of appetite, blood lose anemia, diarrhea and secondary infection due to damage of intestinal mucosa (Ackert and Herrick, 1928;Ramadan and Abou Znada,1991). Drooping wings, decrease egg production (Ackert and Herrick, 1928).…”

| 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.
