A new study led by ISGlobal has identified a gene called PfAP2-HS that allows the malaria parasite to defend itself from febrile temperatures and other adverse conditions within the host. The study found that this gene activates a protective response against high temperatures, helping the parasite survive in the host's environment.
A team of researchers discovered that single-celled organisms like protozoa can protect pathogenic bacteria and prime them for human infection. The bacteria are expelled into the environment after being ingested by protozoa and become more infectious in humans, potentially threatening public health.
