Background: Emergence of resistance to antimalarial drugs presents a major drawback in efforts to control malaria. To address this problem, there is an urgent and continuous need for the development of new and effective antimalarial agents. (L.

Article Synopsis
  • Zika virus (ZIKV), first identified in 1947, is spread by insects and has been linked to outbreaks, with nonhuman primates (NHPs) possibly acting as a reservoir.
  • Researchers examined 212 archived serum samples from NHPs in Kenya, collected between 1992 and 2017, to check for ZIKV antibodies using a microneutralization test.
  • The study found ZIKV antibodies in 38 samples (17.9%), indicating that NHPs in Kenya may play a role in ZIKV transmission and maintenance in the environment.

Naturally acquired immunity to malaria develops over several years and can be compromised by concomitant infections. This study explored the influence of chronic schistosomiasis on clinical outcome and immunity to repeated malaria infection. Two groups of baboons ( = 8 each), were infected with Schistosoma mansoni cercariae to establish chronic infections.

Intranasal instillation of SE36, a malaria vaccine candidate antigen, in lactating BALB/c strain (derived from the Bagg and albino laboratory inbred mice) female mice resulted in the appearance of the antigen in breast milk as demonstrated by sandwich ELISA and Western blot. Pups born of immunologically naive mice and breastfed on lactating foster mothers exposed intranasally to SE36 developed IgG anti-SE36 antibodies. These data demonstrate that maternal immunization in mice by this route in lactating mothers can result in active immunization of offspring via ingestion of breast milk containing antigen.
