Fleas of black rats (Rattus rattus) as reservoir host of Bartonella spp. In Chile
Rattus rattus is a widely distributed, invasive species that presentsan important role in disease transmission, either directly or through vectorarthropods such as fleas. These black rats can transmit a wide variety of pathogens, including bacteria of the genus Bartonella, which can cause diseases i...
