Dynamics of Toxoplasma gondii Oocyst Phagocytosis by Macrophages

, 2020
International audienceOocysts are the environmentally resistant stage of the protozoan parasite Toxoplasma gondii. They are responsible for foodborne infections in humans and animals worldwide. Infectious oocysts contain sporozoites that have to exit the

Survey of Gastrointestinal Parasites of Farmed Pigs in Ghana

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Survey of Gastrointestinal Parasites of Farmed Pigs in Ghana Gastrointestinal parasites were common in pigs sampled from Kpone Katamanso Municipality, Ghana, with an overall prevalence of 67.6%. Complementary formol–ether concentration, modified McMaster, and modified Ziehl–Neelsen techniques improved parasite detection, while polymerase chain reaction

In Vitro Oocyst Sporozoite Release Assay

, 2013
Release of oocyst sporozoites at 25 °C in vitro in the presence of trypsin (50 μg/ml) at day 14 PI. Y-axis represents released sporozoites as a percentage of total oocyst sporozoites. X-axis indicates the time point when the samples are collected. In the

Shedding of oocysts by immunocompetent individuals with cryptosporidiosis [PDF]

Journal of Hygiene, 1985
SUMMARYStudies were made on 33 immunocompetent patients with cryptosporidiosis (31 of them children) to determine how long oocyst shedding continued after the cessation of diarrhoea. The majority (20/33) ceased to shed oocysts in the week following the cessation of diarrhoea. However 5 patients (15%) continued to shed oocysts for 2 weeks or more, and 1

Estimating the Economic Impact of Neonatal Calf Diarrhea Agents With Decision Tree Analysis and the Monte Carlo Simulation Model

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aims to determine the economic impacts of the major agents causing diarrhoea in newborn calves using Monte Carlo simulation and decision tree analysis. According to the study results, the cost per animal was $13.7 for healthy calves without diarrhoea.

Protein O-Fucosyltransferase 2 Is Not Essential for Plasmodium berghei Development

Frontiers in Cellular and Infection Microbiology, 2019
Thrombospondin type I repeat (TSR) domains are commonly O-fucosylated by protein O-fucosyltransferase 2 (PoFUT2), and this modification is required for optimal folding and secretion of TSR-containing proteins.

Detection and Confirmation of Toxoplasma Oocysts in the Soil

The Japanese Journal of Veterinary Science, 1975
An outbreak of swine toxoplasmosis occurred in a hoggery in Shizuoka Pre-fecture. In the hoggery, pigs had been fed soil with pig-feed for 3 consecutive days from1 week before the outbreak of the disease. Toxoplasma oocysts were detected directly fromthe soil in the hoggery.A combination (Metlaod III) of ultrasonic treatment and sugar floatation method

Gastrointestinal Parasites of Domestic Ducks (Anas platyrhynchos domesticus) in Kathmandu, Nepal

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Gastrointestinal parasites in ducks raised on smallholder farms in Kathmandu, Nepal, are investigated using copromicroscopic examination. A diverse range of protozoa and helminth parasites are detected including the first records of Entamoeba spp., Cryptosporidium sp. and Tyzzeria sp. in ducks in Nepal.

Recognition and characterization of stage-specific oocyst/sporozoite antigens of Toxoplasma gondii by human antisera. [PDF]

, 1985
Human infection with Toxoplasma gondii is presumed due to the ingestion of either tissue cysts containing bradyzoites or oocyst/sporozoites that are excreted in the feces of infected cats.
