An In Vitro Assay of Disinfectants on the Viability of Heterakis gallinarum Eggs
Avian Diseases, 2019Nematodes are widespread and common in poultry. Disinfectants are used to reduce infection rates in poultry houses, but there is little documentation of their effectiveness. An in vitro assay was developed to test the efficacy of products to damage Heterakis gallinarum eggs, and nine disinfectants and chemicals commonly used in the poultry industry ...

Labial Sense Organs of the Nematode, Heterakis gallinarum
Journal of Parasitology, 1977The labial sense organs of Heterakis gallinarum (Schrank 1788) were examined by scanning and transmission electron microscopy. Two large doublet papillae are visible externally on the dorsal lip while a single doublet papilla, a short peglike ventrolateral papilla, and the opening of the amphid are visible on each subventral lip.

Heterakis gallinarum, the Cecal Nematode of Gallinaceous Birds: A Critical Review
Avian Diseases, 2019Heterakis gallinarum is a heavily prevalent poultry parasite that thrives in the ceca of various species of gallinaceous birds. It is a small roundworm, measuring between 4 and 15 mm long, in the family Heterakidae. Heterakis gallinarum has a direct life cycle not requiring an intermediate host to complete development, and it is generally believed that

Co-expulsion of Ascaridia galli and Heterakis gallinarum by chickens
International Journal for Parasitology, 2018Worm expulsion is known to occur in mammalian hosts exposed to mono-species helminth infections, whilst this phenomenon is poorly described in avian hosts. Mono-species infections, however, are rather rare under natural circumstances. Therefore, we quantified the extent and duration of worm expulsion by chickens experimentally infected with both ...

Cecal and Hepatic Granulomas in Chickens Associated with Heterakis gallinarum Infection
Avian Diseases, 1988Heterakis gallinarum infection was detected in the ceca of chickens with cecal and hepatic granulomas found at slaughter. The chickens were diagnostic submissions from four small backyard flocks in Saskatchewan. Detailed dissection of some cecal granulomas in one flock and pepsin digestion of cecal granulomas in the three other flocks demonstrated the ...

Experimental Infections with Histomonas meleagridis and Heterakis gallinarum in Ducks and Geese
Journal of Parasitology, 1974Heterakis gallinarum and Histomonas meleagridis have been reported sporadically from ducks and geese. Experimentally, neither bird could be infected by rectal inoculation of H. meleagridis until a strain of Histomonas was isolated that had multiplied in geese following its introduction by eggs of Heterakis gallinarum. H.

Isolation of Histomonas meleagridis from Embryonated Eggs of Heterakis gallinarum*
Journal of Protozoology, 1970SYNOPSIS. Histomonas meleagridis was isolated from eggs of Heterakis gallinarum by culturing artificially hatched eggs in a modified DeVolt's alkaline serum medium. The presence of the protozoon in the cultures was established by microscopic examination and confirmed by producing histomonosis in turkeys by intracecal inoculation with quantities of ...

PCR detection of Heterakis gallinarum in environmental samples
Veterinary Parasitology, 2019Heterakis gallinarum is a widely distributed cecal nematode that parasitizes gallinaceous birds including chickens and turkeys. H. gallinarum infection poses a problem for the poultry industry as the nematode egg serves as a vector for the protozoan parasite, Histomonas meleagridis, the causative agent of histomonosis.

The role of oxygen availability in the embryonation of Heterakis gallinarum eggs
International Journal for Parasitology, 2000The importance of oxygen availability in the embryonation of the infective egg stages of the gastrointestinal nematode parasite Heterakis gallinarum was studied in the laboratory. Unembryonated H. gallinarum eggs were kept under either aerobic conditions by gassing with oxygen, or anaerobic conditions by gassing with the inert gas nitrogen, under a ...

THE WILD TURKEY AS A HOST FOR Heterakis gallinarum AND Histomonas meleagridis
Journal of Wildlife Diseases, 1975Freshly embryonated eggs of Heterakis gallinarum gathered from naturally infected domestic turkeys and chickens developed the first 4 weeks essentially as well in young wild turkeys as in domestic poults, but then became progressively retarded and failed in most birds to result in females with fertile eggs.
