Awareness and Uptake of HIV Preexposure Prophylaxis and Postexposure Prophylaxis Among College Students With Sexual Experiences: Institutional-Based Cross-Sectional Study.

Background: Evidence has shown that HIV prevalence among young people, especially college students, has increased disproportionately. Preexposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) are two of the most effective ways to prevent HIV, which are vital for college students with sexual experiences who have sexual risks.

Objective: To provide evidence for effective intervention to reduce the risk of HIV infection among young students, this study aimed to analyze the awareness and uptake of HIV PrEP and PEP among college students with sexual experiences.

Effects of a blood-free mosquito diet on fitness and gonotrophic cycle parameters of laboratory reared Anopheles gambiae sensu stricto.

Background: The current rise of new innovative tools for mosquito control, such as the release of transgenic mosquitoes carrying a dominant lethal gene and Wolbachia-based strategies, necessitates a massive production of mosquitoes in the insectary. However, currently laboratory rearing depends on vertebrate blood for egg production and maintenance. This practice raises ethical concerns, incurs logistical and cost limitations, and entails potential risk associated with pathogen transmission and blood storage.

Real-time PCR detection of mixed Plasmodium ovale curtisi and wallikeri infections in human and mosquito hosts.

Plasmodium ovale curtisi (Poc) and Plasmodium ovale wallikeri (Pow) represent distinct non-recombining Plasmodium species that are increasing in prevalence in sub-Saharan Africa. Though they circulate sympatrically, co-infection within human and mosquito hosts has rarely been described. Separate 18S rRNA real-time PCR assays that detect Poc and Pow were modified to allow species determination in parallel under identical cycling conditions.

Seasonality and transmissibility of Plasmodium ovale in Bagamoyo District, Tanzania.

Background: Plasmodium ovale is a neglected malarial parasite that can form latent hypnozoites in the human liver. Over the last decade, molecular surveillance studies of non-falciparum malaria in Africa have highlighted that P. ovale is circulating below the radar, including areas where Plasmodium falciparum is in decline.
