Article Synopsis
  • The study investigated how azithromycin and doxycycline affect the vaginal microbiota in women with Chlamydia trachomatis infection as part of the Chlazidoxy trial, analyzing samples from 284 participants.
  • The results showed that a significant portion of the women had a high-risk microbiota at the beginning, but after 6 weeks of treatment, there were no significant changes in microbiota composition or diversity between the two groups.
  • The findings suggest that the vaginal microbiota remains susceptible to reinfection after treatment with either antibiotic, highlighting a preference for doxycycline due to its greater effectiveness against anorectal infections.

Background: For several decades, an increase in disease or pest emergences due to anthropogenic introduction or environmental changes has been recorded. This increase leads to serious threats to the genetic and species diversity of numerous ecosystems. Many of these events involve species with poor or no genomic resources (called here "orphan species").

Purpose: We evaluated laser flare photometry (LFP) values in patients with juvenile idiopathic arthritis (JIA)-associated uveitis.

Methods: Retrospective study. A decrease of the LFP value between baseline visit and 1 month after anti-inflammatory treatment intensification allowed us to define two groups of patients: group 1 (decreased LFP value ≥50%) and group 2 (<50%).

Hybridizations between species and subspecies represented major steps in the history of many crop species. Such events generally lead to genomes with mosaic patterns of chromosomal segments of various origins that may be assessed by local ancestry inference methods. However, these methods have mainly been developed in the context of human population genetics with implicit assumptions that may not always fit plant models.

Clouds constitute the uppermost layer of the biosphere. They host diverse communities whose functioning remains obscure, although biological activity potentially participates to atmospheric chemical and physical processes. In order to gain information on the metabolic functioning of microbial communities in clouds, we conducted coordinated metagenomics/metatranscriptomics profiling of cloud water microbial communities.
