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.

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

Effects of X-ray dosages on development of Heterakis gallinarum
Experimental Parasitology, 1966Abstract Exposure of unsegmented eggs of Heterakis gallinarum to X-irradiation (4,000 to 120,000 R) revealed that dosages up to 64,000 R retarded embryogenesis and 120,000 R appeared lethal. At 64,000 R, the majority of eggs required 15 days longer incubation to develop to infective larvae than did the controls.

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
The 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.

Acquisition and liberation of Histomonas wenrichi by Heterakis gallinarum
Experimental Parasitology, 1968Abstract Simultaneous infections with Histomonas wenrichi Lund, 1963 and Heterakis gallinarum (Schrank, 1788) Madsen, 1949, were established in 15 chickens and seven turkeys. In six chickens and two turkeys, at least one female Heterakis developed eggs that transmitted H. wenrichi when fed to chicks and poults.

Post-Labial Sensory Structures on the Cecal Worm, Heterakis gallinarum
The Journal of Parasitology, 1976Sense organs that lie just posterior to the lips on the sides of the body of Heterakis gallinarum have been examined by scanning and transmission electron microscopy. The sense organs appear externally as a short peg surrounded by a collarlike elevation of cuticle.

Labial Sense Organs of the Nematode, Heterakis gallinarum
The 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.

Performance in Chickens and Turkeys of Chicken-Adapted Heterakis gallinarum
Journal of Helminthology, 19701. Helerakis gallinarum recovered from chickens, and apparently having lived exclusively or predominantly in chickens for several years, thrived better in chickens than in turkeys, when several hundred embryonated eggs were given in a single feeding.2.

Ultrastructure of intestinal cells of Heterakis gallinarum.
Angewandte Parasitologie, 1978Ultrastructure of intestinal cells of Heterakis gallinarum is described and compared with that of Ascaridia galli from ecomorphological point of view. The great analogy in bionomy and ecology of both worms is reflected in the great analogy of ultrastructural construction. A new organoid in the intestinal cells of H.
