Article Synopsis
- * It finds that antibiotic treatment in humans and non-human primates (NHPs) correlates with a higher prevalence of MRSA compared to wild species like micromammals and bats, indicating that antibiotic pressure influences resistance acquisition.
- * The research suggests that generalist MRSA strains, those that can infect various hosts, have a higher potential for spreading antibiotic resistance than specialist strains, highlighting the importance of host diversity in the dynamics of antibiotic resistance in ecosystems.
Oesophagostomosis is a zoonotic disease caused by nematodes of the genus in the intestinal walls of many species, including ruminants, pigs, humans, and nonhuman primates. Although great apes appear to tolerate the parasite in the wild, they can develop a clinical form that can lead to death in captivity and the natural environment. At the Primatology Centre of the International Centre for Medical Research in Franceville (CIRMF) in Gabon, we recorded 4 deaths of chimpanzees () caused by spp.

Different factors have been studied but the potential influence of pathogens has never been investigated. Sex differences, especially in hormones and resource allocation, generate a differential response to pathogens and thereby shape sex differences in lifespan or aging.

Among the HGT mechanisms, natural transformation stands out as being encoded by the bacterial core genome. Natural transformation is often viewed as a way to acquire new genes and to generate genetic mixing within bacterial populations.

- The study aimed to clarify the genetic, morphological, and acoustic differences between two cryptic bat species, P. alitonus and P. rubiginosus, found in caves in French Guiana, using a combination of intensive sampling and advanced molecular techniques.
- Researchers developed a multiplex of 20 microsatellite markers and genotyped 748 individuals, revealing distinct genetic lineages with minimal hybridization (0.1-4%) and more introgression (7.5%) in mitochondrial DNA.
- Findings suggest that low hybridization rates may be influenced by differences in life cycles and sex characteristics between the two species, highlighting the complexity of species boundaries in Pteronotus parnellii and indicating the need for further evolutionary studies.
