Toxoplasma from the Eggs of the Domestic Fowl ( Gallus gallus )

Abstract

Toxoplasmata of varying grades of virulence were isolated from eggs laid by clinically asymptomatic hens and from their internal organs. The strains so recovered were identified as Toxoplasna gondii by morphological, serological, cultural, and pathogenic criteria. These findings strongly suggest that toxoplasmosis may be contracted through the eating of raw or undercooked infected eggs.

Toxoplasma gondiiInfections in Chickens (Gallus domesticus): Prevalence, Clinical Disease, Diagnosis and Public Health Significance

“…A false report of the presence of T. gondii in eggs of poultry (Pande et al., 1961) led Kunert and Werner (1963) to investigate the survival of T. gondii in eggs experimentally inoculated with tachyzoites. T. gondii survived in egg yolk and albumin eggs boiled for 3 min and yolk of eggs fried for 3 min.…”

Negative seroprevalence forToxoplasma gondiiin free‐living primates from Central Amazonia

“…In addition, these species have very generalist behavior, which increase the likelihood of infection. Howler monkeys, for example, frequently descend to the ground to ingest soil to supplement the diet with minerals 21 and, eventually, can consume bird eggs, 22 which are a potential source of infection 23 . Likewise, capuchin monkeys often forage on the ground, 24 are omnivorous and can even feed on small vertebrates, 25 which are also potential sources of infection.…”

Therefore, the negative serologies we found for these species may suggest that these populations have not had contact with the parasite and, consequently, do not have antibodies anti-T. gondii.…”

A Review of the Types of Scientific Misconduct in Biomedical Research

“…Pande et al published an article on toxoplasmosis in the Science journal where one of the photographs was a copy of a photograph published earlier in some other journal by a different author. The editors of the Science magazine subsequently published a regret letter about this (Pande et al 1961;Frankel 1956).…”
