Low seroprevalence of Zika virus in Cameroonian blood donors BJID
Gake,Bouba; Vernet,Marie A.; Leparc-Goffart,Isabelle; Drexler,Jan Felix; Gould,Ernest A.; Gallian,Pierre; Lamballerie,Xavier de.
Abstract A Zika virus seroepidemiology study was performed in 1084 blood donors collected from August to October 2015 in six sites of Cameroon representing a large panel of eco-environments. Samples were tested using an anti-NS1 IgG ELISA detection kit and positives were further confirmed by seroneutralization. The observed global seroprevalence was low (around 5%, peaking at 10% and 7.7% in Douala and Bertoua, respectively) with risk factors associated with seropositivity pointing to the existence of a local (peri-)sylvatic cycle of transmission. These results call attention to the potential introduction and subsequent spread in African urban areas of Asian genotype Zika virus currently circulating in the Americas and adapted to transmission by...

Meireles,Luciana Regina; Galisteo Jr.,Andrés Jimenez; Andrade Jr.,Heitor Franco de.
Toxoplasmosis is one of the most prevalent parasitic infections of man and livestock, and its transmission has usually been attributed to ingestion of undercooked or raw meat from infected livestock, with the infection rate in those animals being an important risk predictor of human disease, high in Brazil and São Paulo State. Looking for this public health problem, we tested serum samples from cattle, goat, sheep and chicken from the State of São Paulo, Brazil, for IgG antibodies to Toxoplasma gondii by enzyme-linked immunosorbent assay (ELISA). Antibodies to Toxoplasma gondii were found in 31.00% (62/200) of sheep, 17.00% (34/200) of goat and 11.00% (22/200) of cattle, without positive sample in chicken. Despite differences in feeding habits of each...
