Arenavirus infection correlates with lower survival of its natural rodent host in a long-term capture-mark-recapture study.

ABSTRACT:

Background

Parasite evolution is hypothesized to select for levels of parasite virulence that maximise transmission success. When host population densities fluctuate, low levels of virulence with limited impact on the host are expected, as this should increase the likelihood of surviving periods of low host density. We examined the effects of Morogoro arenavirus on the survival and recapture probability of multimammate mice (Mastomys natalensis) using a seven-year capture-mark-recapture time series. Mastomys natalensis is the natural host of Morogoro virus and is known for its strong seasonal density fluctuations.

Results

Antibody presence was negatively correlated with survival probability (effect size: 5-8% per month depending on season) but positively with recapture proba
