Seasonal diet-based resistance to anticoagulant rodenticides in the fossorial water vole (Arvicola amphibius).

Anticoagulant rodenticides (AR) resistance has been defined as "a major loss of efficacy due to the presence of a strain of rodent with a heritable and commensurately reduced sensitivity to the anticoagulant". The mechanism that supports this resistance has been identified as based on mutations in the Vkorc1 gene leading to severe resistance in rats and mice. This study evaluates the validity of this definition in the fossorial water vole and explores the possibility of a non-genetic diet-based resistance in a strict herbivorous rodent species.

Resistance to anticoagulant rodenticides in Martinique could lead to inefficient rodent control in a context of endemic leptospirosis.

Leptospirosis is a re-emergent worldwide zoonosis. It is endemic in Martinique where transmission conditions are favourable. Humans are usually infected through contact with water contaminated with urine of rodents.

House Mice as a Real Sanitary Threat of Human and Animal Leptospirosis: Proposal for Integrated Management.

Leptospirosis is a reemerging zoonosis and ranges in severity from benign to sometimes fatal. In cattle, infection may be responsible for abortion and infertility cases causing economic losses. Humans may be contaminated through direct contact with urine of infected animals or indirectly though interaction with urine-contaminated environment.

Overview of laboratory methods to diagnose Leptospirosis and to identify and to type leptospires.

Leptospirosis is a virulent zoonosis with a global distribution. Pathogenic spirochetes of the genus Leptospira are responsible for this disease, and the primary animal reservoirs are rodentvvvs. Direct and indirect contact with infected urine constitutes the main route of transmission.
