Mixed transmission modes promote persistence of an emerging tick‐borne pathogen
Ecosphere, Volume 11, Issue 6, June 2020., 2020 Abstract Pathogens utilize different modes of transmission to maximize transmission success. In vector‐borne disease systems, both vertical and horizontal modes of transmission are common, but the relative contribution of these modes is not well understood but may be determined by host genetics, physiology, or environmental conditions.

Journal of Veterinary Internal Medicine, Volume 34, Issue 2, Page 742-753, March 2020., 2020 Abstract Background Proteinuria is a risk factor for progressive kidney injury in dogs. Enhanced understanding of potential associations between canine vector‐borne diseases (CVBD) and proteinuria is needed. Objectives To determine the proportion of evaluated proteinuric dogs exposed to ≥1 CVBD, including Babesia spp., Ehrlichia spp., spotted‐fever ...

An autochthonous confirmed case of Rickettsia parkeri rickettsiosis in Uruguay
Ticks and Tick-borne Diseases, 2018 Rickettsia parkeri, a member of the spotted fever group (SFG) rickettsiae, was first confirmed as an etiological agent of human rickettsiosis in 2004. Nearly all cases are characterized by an inoculation eschar, and no fatalities have been reported. In Uruguay, probable human cases of R. parkeri infection (confused initially with R.

Rickettsia parkeri colonization in Amblyomma maculatum: the role of superoxide dismutases [PDF]
Parasites & Vectors, 2016 The Gulf Coast tick (Amblyomma maculatum) is an arthropod vector of Rickettsia parkeri, the causative agent of American boutonneuse fever and an infectious agent of public health significance. In this study, we evaluated the biological significance of the superoxide dismutases (SODs) of A. maculatum in hematophagy and R. parkeri colonization within the
