Bartonella spp. infections in Rodents of Cambodia, Lao PDR, and Thailand: Identifying risky habitats

Jiyipong T., Morand S., Jittapalapong S., Rolain J.M.. 2015. Vector Borne and Zoonotic Diseases, 15 (1) : p. 48-55.

This study investigated the type of environmental habitat that may explain the infection of 1176 individuals from 17 rodent species by Bartonella species in seven sites in Cambodia, Lao PDR, and Thailand. No effects of host sex and host maturity on the level of individual infection by all Bartonella spp., but significant effects of locality, season, and host species were observed. The patterns differed when investigating the three more prevalent Bartonella species. For B. rattimassiliensis, season and habitat appeared to be significant factors explaining host infection, with higher levels of infection in wet season and lower levels of infection in rain-fed field, dry field, and human settlement habitats compared to forest habitat. The infection by B. queenslandensis was found to vary, although not significantly, with season and locality, and Bartonella n. sp. (a species mostly associated with Mus spp.) was found to be more prevalent in the wet season and dry field habitat compared to forest habitat. We discuss these results in relation to rodent habitat specificity. (Résumé d'auteur)
