Excretion of Histomonas meleagridis following experimental co-infection of distinct chicken lines with Heterakis gallinarum and Ascaridia galli [PDF]

Parasites & Vectors, 2021
Background Histomonosis is a severe re-emerging disease of poultry caused by Histomonas meleagridis, a protozoan parasite which survives in the environment via the cecal worm Heterakis gallinarum. Following infection, the parasites reside in the ceca and

Identification of the main intestinal helminths of local breed chickens (Gallus gallus domesticus Linnaeus, 1758) reared in traditional mode in the Oran region [PDF]

Helminthologia, 2022
In order to gain a better etiological and epidemiological knowledge of the parasitic diseases of local breed chickens reared in extensive (traditional) mode, a study was carried out in the Oran region during the periods from February 2020 to April 2020 ...

Morpho-molecular characterization and phylogenetic analysis of the Heterakidae nematode isolated from free-range chickens in the Sulaymaniyah Province, Iraq [PDF]

Veterinary World
Background and Aim: Heterakis gallinarum is a parasitic nematode that commonly infects the ceca of domestic and wild gallinaceous birds, acting as a vector for Histomonas meleagridis, the causative agent of blackhead disease. Despite its sig­nificance in

1H-NMR based-metabolomics reveals alterations in the metabolite profiles of chickens infected with ascarids and concurrent histomonosis infection [PDF]

Gut Pathogens, 2023
Background Gut infections of chickens caused by Ascaridia galli and Heterakis gallinarum are associated with impaired host performance, particularly in high-performing genotypes.

Morphomolecular identification of heavy parasitic typhlitis in layer flocks: tissue response and cell-mediated reaction [PDF]

Acta Veterinaria Scandinavica
Background Heterakis gallinarum (H. gallinarum) is a common poultry parasite that can be found in the ceca of many gallinaceous bird species, causing minor pathology and reduced weight gain.

Intestinal Helminth Communities of Grey Partridge Perdix perdix and Common Pheasant Phasianus colchicus in Poland [PDF]

Animals, 2021
The aim of this study was to describe the morphology and means of identification of helminths in native partridges (65) and introduced pheasants (32) in Poland and to determine the level of intestinal infection of these birds by helminths using ...

Density related effects on lifetime fecundity of Heterakis gallinarum in chickens [PDF]

Parasites & Vectors, 2014
Background Density related effects, both inverse density- and density-dependent, contribute to regulating population dynamics of parasites. We investigated whether density related effects are directly controlling lifetime fecundity of Heterakis ...

Nodular typhlitis associated with the nematodes Heterakis gallinarum and Heterakis isolonche in pheasants: frequency and pathology with evidence of neoplasia

Memorias Do Instituto Oswaldo Cruz, 2003
An investigation related to the frequency and pathology of Heterakis gallinarum and pathology of Heterakis isolonche in pheasants from Rio de Janeiro, Brazil was conducted by means of clinical examinations, necropsies, and histopathological analysis in ...

Co‐Infection, but Not Infection Intensity, Increases Shedding in a Gastrointestinal Helminth of Gamebirds [PDF]

Ecology and Evolution
Host heterogeneity in disease transmission is commonly seen across host‐pathogen systems, and identifying individuals who contribute disproportionately to pathogen transmission (i.e., superspreaders) is key to understanding disease dynamics and managing ...
