Evasion of autophagy mediated by Rickettsia surface protein OmpB is critical for virulence. [PDF]

, 2019
Rickettsia are obligate intracellular bacteria that evade antimicrobial autophagy in the host cell cytosol by unknown mechanisms. Other cytosolic pathogens block different steps of autophagy targeting, including the initial step of polyubiquitin-coat ...

A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

Pest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

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.

Detection and Genetic Diversity of Heritable Bacterial Symbionts in Human Lice Based on 16S‐rRNA Gene

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Candidatus Riesia pediculicola and Wolbachia were found in 79.6% and 95.2% of head lice, and 81.8% and 100% of body lice. Candidatus Riesia pthiripubis and Wolbachia appeared in 41.7% and 75% of pubic lice. Maximum‐likelihood 16S‐rRNA phylogeny revealed substantial heterogeneity within symbiont populations. ABSTRACT Human lice are obligate bloodsucking

Epidemiology of Acute Q Fever, Scrub Typhus, and Murine Typhus, and Identification of Their Clinical Characteristics Compared to Patients with Acute Febrile Illness in Southern Taiwan

Journal of the Formosan Medical Association, 2009
In Taiwan, acute Q fever, scrub typhus, and murine typhus (QSM diseases) are the most common rickettsioses, but their epidemiology and clinical characteristics have not been clarified. Diagnosis of these three diseases based on clinical manifestations is

Molecular Characteristics of Rickettsia in Ticks Collected along the Southern Border of Mongolia

Pathogens, 2020
Tick-borne infections are a significant threat to public health, particularly in regions where individuals frequently enter tick habitats. Roughly 26% of the population in Mongolia practice nomadic pastoralism and are considered at high risk of exposure ...

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.

Molecular Screening of Black Flies (Diptera: Simuliidae) for Vector‐Borne Zoonotic Pathogens, South Moravia, Czech Republic

Zoonoses and Public Health, Volume 73, Issue 1, Page 95-106, February 2026.
ABSTRACT Introduction Black flies (Simuliidae) are globally distributed blood‐feeding arthropods and vectors of viral, bacterial, and parasitic pathogens to many animal species, including humans. We investigated the occurrence of selected vector‐borne pathogens in black flies in South Moravia, Czech Republic, and evaluated their possible role in the ...
