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.

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.

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 ...

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.

Histomonas meleagridis and H. wenrichi: Time of acquisition by Heterakis gallinarum
Experimental Parasitology, 1971Abstract Concurrent infection of young chickens with Histomonas -free Heterakis gallinarum less than 10 days old and Histomonas meleagridis , with or without H. wenrichi , did not result in the acquisition, retention, and subsequent transmission of either protozoan by the next generation of cecal worms. Concurrent infections of chicks or poults

THE RELATIONSHIP BETWEEN EIMERIA TENELLA AND HETERAKIS GALLINARUM INFECTION IN BROILER CHICKENS [PDF]
Kafrelsheikh Veterinary Medical Journal, 2004 The present investigation dealt with the effect of concurrent infections of E. tenella and Heterakis gallinarum in broiler chickens. Six groups of 10 chicks (15 day old) coccidia free Hubbard chicken were used in this work. Group I was infected with 50.000 sporulated oocysts of E. tenella per chick and considered as Eimeria positive control.

Avian Diseases, 1999
Histomoniasis was diagnosed in a commercial turkey flock. All morbidity and mortality occurred in one house. Birds exhibited lesions characteristic for histomoniasis, and the diagnosis was confirmed by histopathologic examination. Affected turkeys were infected with moderate levels of Ascaridia dissimilis but not Heterakis gallinarum.

On the Interaction between Heterakis gallinarum, Ascaridia galli, “Blackhead” and the Chicken
Journal of Helminthology, 1962Measured dosages of larvated eggs of the caecal nematode, Heterakis gallinarum and the small intestinal nematode, Ascaridia galli were fed to domestic chickens, in order to study the distribution of the numbers of worms developing and the influence on the worms and the chicks of the treatments in the experiments.

International Journal for Parasitology, 1974
Abstract The reproductive potential of Heterakis gallinarum was substantially higher in the ring-necked pheasant than in any of the eight other species of galliform birds used on the 67 tests here reported. Pheasants on four tests yielded an average 19·4 times as many eggs that embryonated as were used to infect the birds, while for those on tests ...

[Effect of some trace elements on Heterakis gallinarum invasion].
Veterinarno-meditsinski nauki, 1976It was found that sodium chloride at the rate of 0.5 per cent in the mixtures lowers by 25 times the survival of the Heterakis helminths in birds, prevents the manifestation of verminous typhlitis, alters the ratio between the female and the male worms in favour of the latter, contributes to the increase in body weight and rises the level of the total ...
