Introduction: This study aimed to understand the origin and to explain the maintenance of extended-spectrum β-lactamase (ESBL) isolated from food-producing animals in a third-generation cephalosporin (3GC)-free farm.

Methods: Culture and molecular approaches were used to test molecules other than 3GC such as antibiotics (tetracycline and oxytetracycline), antiparasitics (ivermectin, flumethrin, fenbendazol, and amitraz), heavy metal [arsenic, HNO, aluminum, HNO, cadmium (CdSO), zinc (ZnCl), copper (CuSO), iron (FeCl), and aluminum (AlSO)], and antioxidant (butylated hydroxytoluene) as sources of selective pressure. Whole-genome sequencing using short read (Illumina™) and long read (Nanopore™) technologies was performed on 34 genomes.

Article Synopsis
  • The French West Indies occasionally receive dust from North Africa, which can carry microorganisms that may impact health.
  • A study conducted in 2017 and 2018 analyzed 16 dust samples collected during dust events and 9 control samples to assess the diversity and potential health risks of these microorganisms.
  • Results showed increased bacterial load and diversity during dust events, identifying signature species from NA dust, with metabarcoding revealing potentially pathogenic microorganisms, despite no pathogens found in the cultivable analysis.

Free-living amoebae (FLA) such as Acanthamoeba, Balamuthia mandrillaris, Naegleria fowleri and Sappinia pedata are naturally widespread in freshwater, causing rare but fatal and debilitating infections in humans. Although recent studies have shown an increase in infection rates, there is a paucity of epidemiological studies regarding the presence of these emerging pathogens in water. Herein, we studied the diversity and relative abundance of thermophilic FLA in different recreational baths in a tropical climate for 5 years.

Until 1993, chlordecone (CLD) was extensively used in banana fields in French West Indies. In a previous study, CLD was detected in 90 % of Martinican and Guadeloupean adult's serum. In order to simplify the analyses of CLD in the serum, a new QuEChERS-HPLC-MS/MS method was implemented and validated by the Pasteur Institute of Guadeloupe (IPG).

Background: Angiostrongylus cantonensis (rat lungworm) is the main pathogen responsible for eosinophilic meningitis in humans. One of its intermediate snail hosts, Achatina fulica, was already present in many countries around the world before it appeared in the West Indies in the late 1980s. In the French territories in the Caribbean and northern South America, the first cases of human neuroangiostrongyliasis were reported in Martinique, Guadeloupe and French Guiana in 2002, 2013 and 2017, respectively.
