Rhipicephalus sanguineus sensu lato infestation in an urban area in South Sacramento, California, USA.

ABSTRACT:

Background

The brown dog tick, Rhipicephalus sanguineus sensu lato (Rh. sanguineus s.l.), is an important vector of Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever (RMSF), in western North America, with the most prominent tick infestations occurring in the Southwestern USA and Northern Mexico. RMSF is a significant public health threat in these regions, including in the state of California.

Methods

In 2024, the Sacramento-Yolo Mosquito and Vector Control District detected a brown dog tick infestation in a neighborhood in South Sacramento (CA, USA) that encompassed three adjoining properties. This infestation was unusual due to its location farther north than those in most recent reports. In partnership with the Laboratory of Infectious Disease Ecol
