Quantitative study of Rickettsia massiliae in Rhipicephalus sanguineus organs [PDF]

Ticks and Tick-borne Diseases, 2014
Rickettsia massiliae, belonging to the spotted fever group of Rickettsia, is a human pathogen causing a similar course of disease to that caused by R. conorii, the originally recognized etiologic agent of Mediterranean spotted fever.

Zoonotic Disease Transmission May Be Linked to Host Co‐Occurrence Network Topology

Annals of the New York Academy of Sciences, Volume 1554, Issue 1, Page 110-120, December 2025.
A global analysis of zoonotic host co‐occurrence networks identified 22 networks from five continents (A) and 87 hosts from 16 orders of mostly birds but also mammals (B) as having a high potential for disease transmission. ABSTRACT Most human pathogens are zoonotic, transmitted from vertebrate hosts to humans.

The taxonomic status of Rhipicephalus sanguineus (Latreille, 1806)

Veterinary Parasitology, 2015
The brown dog tick, Rhipicephalus sanguineus sensu stricto, is a species with considerable public health and economic importance. However, the taxonomic status of this species is far from resolved. After more than 110 years of scientific work on R. sanguineus s.s., the situation is that there is no type, no solid description, nor is there a consensus ...

Canine Spotted Fever Group Rickettsial Seroprevalence as an Indicator for Human Rocky Mountain Spotted Fever Case Rates in Arizona, USA

Zoonoses and Public Health, Volume 72, Issue 8, Page 697-705, December 2025.
ABSTRACT Introduction Rocky Mountain spotted fever (RMSF), a rapidly progressing febrile disease caused by the bacterium Rickettsia rickettsii, is the deadliest tick‐borne disease in the world. Human infection initially results in non‐specific symptoms and, if untreated, can result in death in up to 35% of cases.

Prevalence and Identification of Livestock Tick by Sex Ratio and Host in Tehran Province

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
This study identified tick species infesting livestock and poultry in Tehran Province, revealing a female‐biased sex ratio and sheep as the most infested hosts. Rhipicephalus sanguineus sensu lato was the dominant species. These findings underscore the need for host‐targeted tick control to mitigate disease transmission and economic losses.
