Dissemination of spotted fever rickettsia agents in Europe by migrating birds. [PDF]

PLoS ONE, 2010
Migratory birds are known to play a role as long-distance vectors for many microorganisms. To investigate whether this is true of rickettsial agents as well, we characterized tick infestation and gathered ticks from 13,260 migratory passerine birds in ...

A Metabolic Dependency for Host Isoprenoids in the Obligate Intracellular Pathogen Rickettsia parkeri Underlies a Sensitivity to the Statin Class of Host-Targeted Therapeutics. [PDF]

, 2019
Gram-negative bacteria in the order Rickettsiales have an obligate intracellular growth requirement, and some species cause human diseases such as typhus and spotted fever.

Serological and molecular detection of spotted fever group Rickettsia in a group of pet dogs from Luanda, Angola

Parasites & Vectors, 2017
Background Infections with tick-borne rickettsiae can cause diseases well known in humans but still not so well characterized in dogs. Susceptibility to infection depends on the virulence of Rickettsia spp.

Rickettsia conorii Subspecies israelensis in Captive Baboons

Emerging Infectious Diseases, 2023
Hamadryas baboons (Papio hamadryas) may transmit zoonotic vector-borne pathogens to visitors and workers frequenting zoological parks. We molecularly screened 33 baboons for vector-borne pathogens.

Rickettsia felis Infections and Comorbid Conditions, Laos, 2003-2011

Emerging Infectious Diseases, 2014
To the Editor: Fleaborne disease is highly prevalent in Laos, mainly attributed to murine typhus (Rickettsia typhi infection), transmitted by Xenopsylla cheopis fleas, but data on other fleaborne diseases are limited (1).

First molecular diagnosis of the human pathogen Rickettsia raoultii and other spotted fever group rickettsiae in Sudanese ixodid ticks from domestic ruminants

Veterinary Medicine and Science
Background Rickettsial infections are often neglected and poorly recognized by physicians in many tropical and subtropical regions. Despite a number of recent reports describing rickettsial diseases in new locations and the discovery of new rickettsiae ...

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, EarlyView.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

Prevalence of infections and co-infections with 6 pathogens in Dermacentor reticulatus ticks collected in eastern Poland

Annals of Agricultural and Environmental Medicine, 2017
Occurrence of co-infections with various pathogens in ixodid ticks creates a risk of increased severity of tick-borne diseases in humans and animals exposed to bite of the ticks carrying multiple pathogens.

The Effects of X-rays and Beta Rays (Tritium) on the Growth of \u3cem\u3eRickettsia mooseri\u3c/em\u3e and \u3cem\u3eRickettsia akari\u3c/em\u3e in Embryonate Eggs [PDF]

, 1960
The growth of Rickettsia mooseri was accelerated and quantitatively increased in embryonate eggs containing tritium oxide at levels of 180, 90, and 45 mc./egg during the growth period.
