Experimental infection of horses with Rickettsia rickettsii [PDF]

Parasites & Vectors, 2016
Rickettsia rickettsii is vectored by ticks, and some vertebrate hosts can be sources of infection to ticks during bacteremic periods. In Brazil, the main vector for R. rickettsii is the tick Amblyomma sculptum, a member of the A. cajennense complex. Horses, in turn, are one of the major hosts for A. sculptum.

Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT Piscirickettsia salmonis, the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.

Rickettsia slovacaInfection in Humans, Portugal

Emerging Infectious Diseases, 2013
Fifteen years after the initial detection of Rickettsia slovaca in ticks in Portugal, 3 autochthonous cases of R. slovaca infection were diagnosed in humans. All patients had an eschar on the scalp and lymphadenopathy; 2 patients had facial edema. R. slovaca infection was confirmed by serologic testing, culture, and PCR.

Infection Risk From Humans and Animals in the Anatomy Laboratory: A Scoping Review

Clinical Anatomy, Volume 39, Issue 3, Page 346-367, April 2026.
ABSTRACT Whole‐body dissection is a cornerstone of anatomy education. During and following the COVID‐19 pandemic, exposure to infectious agents and other risks of dissection were highlighted. To identify potential risks, one must have the data outlining these risks in specific situations.

Early Tick Species Identification Using Eschar‐Based PCR to Guide Presymptomatic Risk Assessment in Tick‐Borne Diseases

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT In endemic regions where simultaneous larval tick bites frequently occur, early identification of tick species from eschar lesions may substantially influence presymptomatic clinical triage. We report a 78‐year‐old woman who was found after approximately 24 h of wandering, presenting with multiple clustered eschars on the lower extremities and

Borrelia Diversity and Co-infection with Other Tick Borne Pathogens in Ticks [PDF]

, 2017
Identifying Borrelia burgdorferi as the causative agent of Lyme disease in 1981 was a watershed moment in understanding the major impact that tick-borne zoonoses can have on public health worldwide, particularly in Europe and the USA.
