1. Histomonas meleagridis was isolated in culture from the liver lesions of a hen suffering from “blackhead” (enterohepatitis). It has been cultivated at 36·5–37°C. for over a year. 2. Chicks, which had been reared free from protozoa, were inoculated per os or per anum, with cultures of the above strain of H. meleagridis. Eleven out of twelve birds became infected. Caecal lesions only were produced. This strain, although isolated from the liver lesions of a hen suffering from acute blackhead… 

Establishing mono-eukaryotic Histomonas meleagridis cultures from in vivo infection contaminated with Tetratrichomonas gallinarum and Blastocystis spp.

After successful propagation and maintenance of the cultured H.meleagridis, its pathogenicity was affirmed in an infection experiment in turkeys and an easy and successful approach to establish the mono-eukaryotic H. meleag Ridis culture free of other host's protozoa is proposed.

Rapid transmission of the protozoan parasite Histomonas meleagridis in turkeys and specific pathogen free chickens following cloacal infection with a mono-eukaryotic culture

The pathogenicity and transmission of a mono-eukaryotic culture of Histomonas meleagridis for commercial turkeys and specific pathogen free (SPF) chickens is described for the first time and rapid spread of the parasite to in-contact Turkeys and chickens was noticed, based on reisolation of live parasites.

Progression of Histomonosis in Commercial Chickens Following Experimental Infection with an In Vitro Propagated Clonal Culture of Histomonas meleagridis

The high susceptibility of commercial chicken lines to histomonosis could be demonstrated and characterized by severe lesions in the ceca and insignificant involvement of the liver, approaching a maximum on days 7–14 postinfection.

Histomonosis in Poultry: A Comprehensive Review

Safety and stability of live-attenuated isolates have been demonstrated, and highly efficacious protection has been conferred in experimental settings with administration of these isolates without harming performance, encouraging for vaccine development.

Blackhead Disease (Histomoniasis) in Poultry: A Critical Review

It was demonstrated that histomoniasis could spread rapidly through a flock of turkeys by direct contact, probably involving the phenomenon of cloacal drinking, and the lack of suitable treatment drugs or vaccines emphasizes the importance of prevention by worm control and management.

Pathogenesis of Histomonosis in Experimentally Infected Specific-Pathogen-Free (SPF) Layer-Type Chickens and SPF Meat-Type Chickens

The results of the present study suggest that the genetic background of the birds influences the reaction to infection with H. meleagridis and is suggested to be significantly higher in LT chickens than in MT chickens.

Identification and molecular characterization of numerous Histomonas meleagridis proteins using a cDNA library

SUMMARY Histomonas meleagridis is a protozoan parasite of various galliform birds causing a type of enterohepatitis termed histomonosis or ‘blackhead disease’. Due to the ban of chemotherapeutic



Cultivation of Histomonas meleagridis from the Liver Lesions of a Hen

All attempts to cultivate the parasite from diseased tissues from either turkeys or chickens failed, and Tyzzer cultivated Histomonas meleagridis from the cæcal discharges of experimentally infected chickens.

A Description of Embadomonas n.spp. from Blatta orientalis, Rana temporaria, Bufo vulgaris, Salamandra maculosa; with a Note upon the “Cyst” of Trichomonas batrachorum

Embadomonas blattae a new species from the hind gut of Blatta orientalis is described, differs from other known species of this flagellate in shape, and in absence of a definite karyosome, and is proposed to call E. dobelli.

On the Cultivation of Entamoeba histolytica and some other Entozoic Amoebae

Methods by which cultures of entozoic amoebae can be initiated from encysted forms have been discovered and are described, and some indications are given for the isolation of pure strains from mixed cultures.

The Morphology and Method of Division of Trichomonas

1. Three trichomonads have been cultivated and studied, T. hominis, Trichomonas sp. from M. nemestrinus (= R.T. strain), and T. batrachorum from English frogs and toads. 2. A number of strains of T.


Feeding embryonated eggs of Heterakis papillosa to brooder chickens led to a disease of both ceca, characterized by the presence of a core consisting of fecal matter, coagulated blood, and emigrated

In 1895 the writer' published an account of the pathological anatomy and parasitology of a highly fatal infectious disease of turkeys commonly known as blackhead. Since then but few opportunities


It now seems highly probable that the turkey has become relatively resistant to the invasion of the protozoan parasite acting alone and that such invasion may require other agencies.

Further Experiments on the Action of Emetine in Cultures of Entamoeba histolytica

In 1926 two of us published the results of a long series of experiments on the toxic action of the alkaloids of ipecacuanha in cultures of several species of entozoic amoebae, which showed clearly that the full specific action of emetine is only disclosed if the alkAloid is allowed to act for a sufficient time.
