Cryopreservation of infectious Cryptosporidium parvum oocysts [PDF]

Nature Communications, 2018
Abstract Cryptosporidiosis in an enteric infection caused by Cryptosporidium parasites and is a major cause of acute infant diarrhea in the developing world. A major bottleneck to research progress is the lack of methods to cryopreserve Cryptosporidium

Some new species of Caryospora (Apicomplexa: Eimeriidae) from brazilian snakes, and a re-description of C. jararacae Carini, 1939

Memorias do Instituto Oswaldo Cruz, 1991
The mature ooxysts of six new species of Caryospora are described from the faeces of Brazilian snakes. They are differentiated from other species previously recorded from reptiles, largely on the size and shape of the oocyst and sporocyst, structure of ...

Survey of Gastrointestinal Parasites of Farmed Pigs in Ghana. [PDF]

Vet Med Sci
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

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.
