Ticks infesting humans in Central America: A review of their relevance in public health

Current Research in Parasitology and Vector-Borne Diseases, 2022
Ticks are blood-sucking arthropods that parasitize most groups of terrestrial or semiaquatic vertebrates. Humans are accidental hosts to the ticks; however, in humans the ticks can cause damages varying from simple irritation to severe allergies ...

The guinea pig model for tick-borne spotted fever rickettsioses: A second look

Ticks and Tick-borne Diseases, 2020
The guinea pig (Cavia porcellus) has an established track record as an animal model, with its utility in rickettsial research documented as early as the turn of the 20th century. From identifying Rickettsia rickettsii as the agent of Rocky Mountain spotted fever and ticks as the natural transmission route to evaluating protective immunity and treatment

Prevalence of Rickettsia species in ticks including identification of unknown species in two regions in Kazakhstan

Parasites & Vectors, 2019
Background Over 60 years ago clinical patterns resembling tick-borne rickettsioses have been described for the first time in Kazakhstan. Since 1995 the incidence of clinical cases of tick-borne rickettsioses in humans seems to be rising but studies on ...

The role of rodents in the ecology of Ixodes ricinus and associated pathogens in Central and Eastern Europe

Frontiers in Cellular and Infection Microbiology, 2013
Rodents comprise more species than any other mammal order. Most rodents are considered keystone species in their ecological communities, hence the survival of many other species in the ecosystem depend on them.

Short Report: First Outbreak of Atlantic Rainforest Spotted Fever in North‐Eastern of Brazil—Clinical Features and Eco‐Epidemiological Investigation

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Since 2010, six cases of Atlantic rainforest spotted fever (ARSF) have been confirmed and reported in Brazil, a tick‐borne disease caused by Rickettsia parkeri strain Atlantic rainforest and associated with the tick Amblyomma ovale. So far, none of the cases have been associated with death. One of the cases occurred in 2018 in the

Beyond the Kidney and Lung: Cutaneous and Mucosal Clues to Human Hantavirus Disease

International Journal of Dermatology, Volume 65, Issue 10, Page 2018-2027, October 2026.
Rodent exposure and aerosolized excreta can lead to hantavirus infection with systemic endothelial injury and capillary leak, resulting in thrombocytopenia and syndromes such as HPS/HCPS and HFRS/NE. Early dermatologic and mucosal findings, including flushing, conjunctival injection, petechiae/purpura, and mucosal bleeding, may provide important clues ...
