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.

(1) Background: Terrestrial mammals in protected areas have been identified as a potential source of antimicrobial-resistant bacteria. Studies on antimicrobial resistance in gorillas have already been conducted. Thus, this study aimed to describe the phylogroups, pathotypes and prevalence of antimicrobial resistance of isolated from western lowland gorilla's faeces living in MDNP.

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%).

Article Synopsis
  • Urinary tract infections (UTIs) are a significant global health issue, leading to high rates of antibiotic use and consultations, especially in community settings.
  • The study aimed to investigate the prevalence and antibiotic resistance of specific uropathogenic strains in Franceville, conducting analysis on 1,086 urine samples over a 17-month period.
  • Results indicated a 29.2% prevalence of UTIs, predominantly affecting women, with notable resistance to certain antibiotics, emphasizing the importance of tailoring antibiotic usage based on local resistance patterns.

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.

Despite the essential role of in health-promoting gut bacteria in humans, little is known about their functions in wild animals, especially non-human primates. It is difficult to determine in vivo the function of Bifidobacterium in wild animals due to the limited accessibility of studying target animals in natural conditions. However, the genomic characteristics of obtained from the feces of wild animals can provide insight into their functionality in the gut.

Lactic acid bacteria (LAB) reside in a wide range of mammals, such as autochthonous intestinal bacteria. In this paper, we present the phenotypic and phylogenetic characteristics of gorilla-specific LAB. -previously isolated from the wild and captive western lowland gorillas ()-were successfully isolated from wild mountain gorillas () in addition to other captive and wild western lowland gorillas.

African rainforest harbors herbivores at high density. However, because plants and soils typically lack in some essential minerals, rainforest is not always a suitable habitat for herbivores. How they fulfill the mineral requirements is therefore an important question to animal ecology and conservation.

Prevalence of drug-resistant bacteria in wildlife can reveal the actual level of anthropological burden on the wildlife. In this study, we isolated two multiple drug-resistant strains, GG6-2 and GG6-1-1, from 27 fresh feces of wild western lowland gorillas in Moukalaba-Doudou National Park, Gabon. Isolates were identified as Achromobacter xylosoxidans and Providencia sp.

Four strains of Gram-staining-positive, anaerobic rods were isolated from the faeces of western lowland gorillas (Gorilla gorilla gorilla). Three strains, KZ01(T), KZ02 and KZ03, were isolated at the Kyoto City Zoo, Japan, and one strain, GG02, was isolated in the Moukalaba-Doudou National Park, Gabon. These strains were investigated taxonomically.

Gram-staining-positive anaerobic rods were isolated from the faeces of a wild lowland gorilla (Gorilla gorilla gorilla) in Moukalaba-Doudou National Park, Gabon, and strain GG01(T) was taxonomically investigated. Based on phylogenetic analyses and specific phenotypic characteristics, the strain belonged to the genus Bifidobacterium. Phylogenetic analysis of its 16S rRNA gene sequence revealed that strain GG01(T) formed a single monophyletic cluster and had a distinct line of descent.

In order to identify the causative agent of imported strongyloidiasis found in a Japanese mammalogist, who participated in a field survey in Tanzania, the hyper-variable region IV (HVR-IV) of 18S ribosomal DNA and partial mitochondrial cytochrome c-oxidase subunit 1 gene (cox1) were analyzed and compared with Strongyloides fuelleborni collected from apes and monkeys of Africa and Japan, and S. stercoralis from humans, apes and dogs. The HVR-IV and cox1 of the patient's worms were identical to or only slightly differed from those of worms parasitic in Tanzanian chimpanzees and yellow baboons, demonstrating that the patient acquired the infection during her field survey in Tanzania.
