Eimeria tenella protein trafficking: differential regulation of secretion versus surface tethering during the life cycle [PDF]
, 2017 Eimeria spp. are intracellular parasites that have a major impact on poultry. Effective live vaccines are available and the development of reverse genetic technologies has raised the prospect of using Eimeria spp.

Viral proteins expressed in the protozoan parasite Eimeria tenella are detected by the chicken immune system [PDF]
, 2016 BACKGROUND: Eimeria species are parasitic protozoa that cause coccidiosis, an intestinal disease commonly characterised by malabsorption, diarrhoea and haemorrhage that is particularly important in chickens.

Viability of preserved Cryptosporidium baileyi oocysts [PDF]
The Korean Journal of Parasitology, 2003 The present study was undertaken to determine the viability and infectivity of oocysts of Cryptosporidium baileyi that had been stored from 1 to 40 months at 4 degrees C preserved in 2.5% potassium dichromate solution. Oocysts of C. baileyi were purified from the feces of experimentally infected chickens using discontinuous sucrose gradients ...

Dynamics of Toxoplasma gondii Oocyst Phagocytosis by Macrophages
Frontiers in Cellular and Infection Microbiology, 2020 Oocysts are the environmentally resistant stage of the protozoan parasite Toxoplasma gondii. They are responsible for foodborne infections in humans and animals worldwide.

Mathematical Modeling of Toxoplasmosis Considering a Time Delay in the Infectivity of Oocysts
Mathematics, 2022 In this paper, we study the effect of the introduction of a time delay on the dynamics of toxoplasmosis. This time delay is the elapsed time from when oocysts become present in the environment and when they become infectious.

Antigen incorporation on Cryptosporidium parvum oocyst walls [PDF]
Memórias do Instituto Oswaldo Cruz, 2001 Cryptosporidium parvum oocysts are the infective stages responsible for transmission and survival of the organism in the environment. In the present work we show that the oocyst wall, far from being a static structure, is able to incorporate antigens by a mechanism involving vesicle fusion with the wall, and the incorporation of the antigen to the ...
