To date, data on animal enteroviruses (EVs) are scarce, especially in Central Africa. The aim of this study was to characterize EVs among pigs and goats in Cameroon and the Central African Republic (CAR). A total of 226 pig and goat faecal samples collected in two previous studies carried out in Cameroon and CAR were pooled and screened with molecular assays targeting EV-Es, EV-Fs and EV-Gs. EV genomes were amplified by RT-PCR and their sequences were obtained by Illumina sequencing and assembly. Based on the capsid sequences, 27 EV-G sequences were identified and assigned to 11 virus types, while no EV-E or EV-F was observed. Phylogenetic analysis revealed that the EV-Gs detected in Central Africa do not form specific clusters compared to EV-Gs previously reported in other continents. This suggests a worldwide circulation of EV-Gs, which is likely due to the massive international trade of live animals. One human EV, EV-C99, which belongs to the species , was detected in pigs. This is the third detection of such an event in a similar context, reinforcing the hypothesis that some EV-Cs could be infecting pigs. Our work provides new data on the genetic diversity of EVs circulating among domestic animals in Central Africa.

Cassava ( Crantz) plays a significant role in the livelihoods of people in Africa, particularly in Côte d'Ivoire. However, its production is threatened by begomoviruses which cause huge yield losses. Some weeds and food crops intercropped with cassava act as reservoirs, thereby facilitating the sustenance and propagation of Cassava mosaic begomoviruses (CMBs), along with other begomoviruses.

Lianas are important components of tropical forest diversity and dynamics, yet little is known about the drivers of their community structure and composition. Combining extensive field and LiDAR data, we investigated the influence of local topography, forest structure, and tree composition on liana community structure, and their floristic and functional composition, in a moist forest in northern Republic of Congo. We inventoried all lianas ≥ 1 cm in diameter in 144 20 × 20-m quadrats located in four 9-ha permanent plots, where trees and giant herbs were inventoried.

Nevirapine, primarily metabolized by CYP2B6 and CYP3A4, exhibits enzyme auto-induction and significant ethnic variability in its pharmacokinetics (PK). These complexities are further exacerbated in HIV-TB co-infected patients, where nevirapine is often co-administered with rifampicin/isoniazid-based anti-tuberculosis (TB) therapies. Rifampicin, a strong CYP3A4 inducer and moderate CYP2B6 inducer, and isoniazid, a moderate CYP3A4 inhibitor, create intricate drug interactions that challenge optimal nevirapine dosing strategies, leading to clinical uncertainty and debate.

Background: Malaria is responsible for 580,000 deaths among children under 5, or 95% of all malaria deaths per year globally. Seasonal Malaria Chemoprevention (SMC) is a malaria control intervention in Togo and other African countries targeting children under 5 years old during the peak malaria transmission season. Delaying access to healthcare for children with malaria can result in serious health problems, including heightened morbidity and mortality, complications related to cerebral malaria and anemia, as well as impaired cognitive development.

Pneumonia is one of the major causes of morbidity and mortality among under-five years old children's worldwide, with Ethiopia having the highest rates among Sub-Saharan African nations. Effective control and preventative measures will be made clear by comprehending the spatial, temporal, and spatiotemporal variation of pneumonia incidence among under-five children. A time series cross-sectional study design was conducted from 1 January 2013 to 31 December 2022 using pneumonia reports obtained from the Central Gondar Zone health department and Gondar administrative health department.
