New antimalarial compounds identified that kill parasites in the mosquito vector

A study has identified and tested 22 compounds that inhibit the development of Plasmodium falciparum—one of the parasites that cause malaria—in the mosquitoes that transmit it. The most effective molecule killed 100% of the parasites present within six minutes, even in insecticide-resistant mosquitoes, according to the study published in Nature. These compounds could be used to treat bed nets.

High-risk Human Papillomavirus (HPV) genotypes linked to reduced male fertility

The sperm of men infected with high-risk genotypes of the human papillomavirus (HPV) suffers more damage from oxidative stress and has a weaker immune response, which can lead to reduced fertility. This is one of the conclusions of a study published in the journal Frontiers in Cellular and Infection Microbiology. The research compared the semen of 20 adults infected with high-risk genotypes, seven infected with low-risk genotypes, and 43 adults without infections.
