Article Synopsis
  • - The study investigates the prevalence of antibiotic-resistant extended-spectrum beta-lactamase (ESBL) in children under 5 suffering from diarrhea in public hospitals in Franceville, Gabon, an area lacking previous research on this topic.
  • - Researchers collected and analyzed 70 fecal samples from young children, identifying 26 strains of bacteria (33.0%) that produced ESBLs, with the majority carrying the bla gene.
  • - The findings reveal a high occurrence of ESBL-producing bacteria, primarily from phylogroup D, indicating potential issues related to the improper use of beta-lactam antibiotics among these children.

Zoopharmacognosy is the study of the self-medication behaviors of non-human animals that use plant, animal or soil items as remedies. Recent studies have shown that some of the plants employed by animals may also be used for the same therapeutic purposes in humans. The aim of this study was to determine the antioxidant and antibacterial activity of Ceiba pentandra, Myrianthus arboreus, Ficus subspecies (ssp.

Article Synopsis
  • The study aimed to assess the prevalence of antibiotic resistance in Enterobacteriaceae from wild mammals in Gabon's national parks, focusing on both intrinsic and acquired resistance.
  • Researchers identified 90 enterobacterial isolates from 130 colonies, with Escherichia coli being the most common species (61%), followed by other species like Enterobacter cloacae and Proteus mirabilis.
  • Findings indicated that most resistant strains were wild type with intrinsic resistance, whereas acquired resistance was limited, particularly in E. coli (11%) and E. cloacae (3%).

Background: The projected UNAIDS goal of ending AIDS by 2030 requires significant global efforts to improve current and future ART strategies. In this study, we assessed viral load (VL) suppression and acquired drug resistance, as well as future efficacy of dolutegravir-based combinations for patients living in semi-rural regions of Gabon.

Methods: Eligible study participants were adults receiving ART and recruited between 2018 and 2019 in Franceville, Gabon.

Antibiotic resistance occurs in the environment by multiplication and the spread of multidrug-resistant bacteria that would be due to an improper and incorrect use of antibiotics in human and veterinary medicine. The aim of this study was to establish the prevalence of producing Extended-Spectrum beta-Lactamase (ESBL) antibiotics from rats and gregarious animals in a semirural area of Gabon and to evaluate the origin of a resistance distribution in the environment from animal feces. The bacterial culture was carried out, and the identification of strains on a specific medium and the antibiotic susceptibility tests allowed establishing the prevalence.

In Gabon, terrestrial mammals of protected areas have been identified as a possible source of antibiotic-resistant bacteria. Some studies on antibiotic resistance in bats have already been carried out. The main goal of our study was to detect extended-spectrum beta-lactamases (ESBLs) that are produced by enterobacteria from bats in the Makokou region in Gabon.

Gout is caused by a chronic hyperuricemia whose complications are not currently well evaluated in Africa. The aim of this study was to determine the prevalence and risk factors of hyperuricemia and gout in 85 patients recruited. A total of 26 cases of hyperuricemia, i.

Background: The epidemiological and molecular characteristics of hepatitis C virus (HCV) infection in the general population have been poorly investigated in Africa. The aim of this study was to determine the prevalence, genotype distribution and epidemic history of HCV in the Gabonese general population.

Methods/principal Findings: A total of 4042 sera collected from adults in 220 villages in all nine administrative areas of the country were screened for antibodies to HCV.

Background: Areas endemic for Plasmodium falciparum, hepatitis B virus (HBV) and hepatitis C virus (HCV) overlap in many parts of sub-Saharan Africa. HBV and HCV infections develop in the liver, where takes place the first development stage of P. falciparum before its further spread in blood.

Background: Intrafamilial and sexual transmission of hepatitis C virus (HCV) are still being debated, and little is known about such transmission in central Africa.

Objective: To examine the rate of intrafamilial transmission of HCV between patients and their household members.

Study Design: A cross-sectional study was conducted in Dienga, a remote village in Gabon, involving 195 household members of 14 index cases of HCV infection.

Background: Hepatitis C virus (HCV) infection is a major global public health problem in both developed and developing countries. The prevalence and genetic diversity of HCV in pregnant women in Gabon, central Africa, is not known. We therefore evaluated the prevalence and the circulating genotypes of HCV in a large population cohort of pregnant women.

Background: Plasmodium falciparum causes severe clinical manifestations by sequestering parasitized red blood cells (PRBC) in the microvasculature of major organs such as the brain. This sequestration results from PRBC adherence to vascular endothelial cells via erythrocyte membrane protein 1, a variant parasite surface antigen.

Objective: To determine whether P.
