Introduction: Amoebiasis is a cosmopolitan disease and the third most deadly of parasitic diseases. Entamoeba histolytica is the only one to be pathogenic. Its transmission is not only related to the faecal peril but also sexual, with cases described among men who have sex with men. A case of unusual sexual transmission is described in this article, aiming to discuss the impact of these ways of transmitting amoebiasis on patient management.
Case Report: We describe the case of an amebic liver abscess in a 27-years-old man who did not travel in endemic areas. After patient interrogation, it seems that the contamination mode was sexual, related to a heterosexual relationship with a new female partner 4 months before the diagnosis. HIV and hepatitis B serologies were negative.
Conclusion: The diagnosis of amoebiasis should be suspected in case of dysentery or liver abscess even if there is no history of travel in endemic areas or of sexual intercourse between men.

Research on incarcerated men indicates low PrEP access even though HIV disproportionately affects them. Intersecting attributes - urban, incarcerated, Black, heterosexual men with substance use diagnoses (SUDs) - improves the odds of HIV transmission/acquisition. It is crucial to determine, among "key populations," who might be eligible to take PrEP.

Sexual reproduction and recruitment enhance the genetic diversity and evolution of reef-building corals for population recovery and coral reef conservation under climate change. However, new recruits are vulnerable to physical changes and the mechanisms of symbiosis establishment remain poorly understood. Here, , a broadcast spawning hermaphrodite reef-building coral, was subjected to settlement and juvenile growth in flow-through seawater at 27.

Background: Attitudes and beliefs regarding HIV among adolescents and young adults (AYA) may influence practices that increase the risk of HIV transmission. The study aimed to determine the attitudes and beliefs regarding HIV among senior secondary students and their sexual practices.
Methodology: It was a cross-sectional descriptive study that involved 1,200 adolescents and young adults (AYA) aged 14-24 years in senior secondary schools in Abakaliki.

Introduction: Molecular surveillance is an important tool for detecting chains of transmission and controlling the HIV epidemic. This can also improve our knowledge of molecular and epidemiological factors for the optimization of prevention. Our objective was to illustrate this by studying the molecular and epidemiological evolution of the cluster including the new circulating recombinant form (CRF) 94_cpx of HIV-1, detected in 2017 and targeted by preventive actions in 2018.

Introduction: People who use drugs (PWUD) are at risk of HIV infection, but the frequency and distribution of transmission-associated behaviors within rural communities is not well understood. Further, while interventions designed to more explicitly affirm individuals' sexual orientation and behaviors may be more effective, descriptions of behavior variability by orientation are lacking. We sought to describe how disease transmission behaviors and overdose risk vary by sexual orientation and activity among rural PWUD.
