Molecular Detection of Toxoplasma gondii in Enclosures of African Primates (Papio papio and Papio hamadryas) at the Municipal Zoo of Bauru, São Paulo State, Brazil. [PDF]
J Med PrimatolABSTRACT Toxoplasmosis is one of the most prevalent parasitic infections in animals and humans worldwide, attracting the attention of many researchers who, in recent decades, have identified the sources of Toxoplasma gondii infections to optimize the adoption of preventive measures. In previous studies, it has been found that humans are infected mainly

Sporulation of Cyclospora sp. oocysts [PDF]
Applied and Environmental Microbiology, 1997 Cyclospora sp. oocysts sporulated maximally at 22 and 30 degrees C for 14 days retarded sporulation. Up to 12% of human- and baboon-derived oocysts previously stored at 4 degrees C for 1 to 2 months sporulated when stored for 6 to 7 days at 30 degrees C.

Effects of drinking-water filtration on Cryptosporidium Seroepidemiology, Scotland [PDF]
, 2014 Continuous exposure to low levels of Cryptosporidium oocysts is associated with production of protective antibodies. We investigated prevalence of antibodies against the 27-kDa Cryptosporidium oocyst antigen among blood donors in 2 areas of Scotland ...

Robust, reproducible, industrialized, standard membrane feeding assay for assessing the transmission blocking activity of vaccines and drugs against Plasmodium falciparum. [PDF]
, 2015 BackgroundA vaccine that interrupts malaria transmission (VIMT) would be a valuable tool for malaria control and elimination. One VIMT approach is to identify sexual erythrocytic and mosquito stage antigens of the malaria parasite that induce immune ...
