Newer Surveillance Data Extends our Understanding of the Niche of Rickettsia montanensis (Rickettsiales: Rickettsiaceae) Infection of the American Dog Tick (Acari: Ixodidae) in the United States [PDF]

Vector-Borne and Zoonotic Diseases, 2023
AbstractBackgroundUnderstanding the geographic distribution ofRickettsia montanensisinfections inDermacentor variabilisis important for tick-borne disease management in the United States, as both a tick-borne agent of interest and a potential confounder in surveillance of other rickettsial diseases.

An Initial Survey forWolbachia(Rickettsiales: Rickettsiaceae) Infections in Selected California Mosquitoes (Diptera: Culicidae) : Table 1 [PDF]

Journal of Medical Entomology, 2004
Knowledge of biogeographic variation in Wolbachia infection rates and inferred susceptibility to infection among different mosquito taxa has fundamental implications for the design and successful application of Wolbachia-based vector-borne disease control strategies.

Exploring the niche ofRickettsia montanensis(Rickettsiales: Rickettsiaceae) infection of the American dog tick (Acari: Ixodidae), using multiple species distribution model approaches [PDF]

Journal of Medical Entomology, 2020
AbstractThe American dog tick, Dermacentor variabilis (Say) (Acari: Ixodidae), is a vector for several human disease-causing pathogens such as tularemia, Rocky Mountain spotted fever, and the understudied spotted fever group rickettsiae (SFGR) infection caused by Rickettsia montanensis.

Feeding byAmblyomma maculatum(Acari: Ixodidae) EnhancesRickettsia parkeri(Rickettsiales: Rickettsiaceae) Infection in the Skin [PDF]

Journal of Medical Entomology, 2014
Rickettsia parkeri Luckman (Rickettsiales: Rickettsiaceae), a member of the spotted fever group of Rickettsia, is the tick-borne causative agent of a newly recognized, eschar-associated rickettsiosis. Because of its relatively recent designation as a pathogen, few studies have examined the pathogenesis of transmission of R.

Effect ofRickettsia rickettsii(Rickettsiales: Rickettsiaceae) Infection on the Biological Parameters and Survival of Its Tick Vector—Dermacentor variabilis(Acari: Ixodidae) [PDF]

Journal of Medical Entomology, 2015
Rocky Mountain spotted fever, caused by Rickettsia rickettsii, is a potentially fatal tick-borne disease spread from North America to Argentina. The major vectors of R. rickettsii in the United States are Dermacentor andersoni Stiles and Dermacentor variabilis (Say). It is generally believed that vector ticks serve as major reservoirs of R.

Optimization of artificial membrane feeding system for lone star ticks, Amblyomma americanum (Acari: Ixodidae), and experimental infection with Rickettsia amblyommatis (Rickettsiales: Rickettsiaceae)

Journal of Medical Entomology, 2023
Abstract With the introduction of siliconized artificial membranes, various artificial feeding systems (AFS) for hard ticks (Ixodidae) have been developed over the last decades. Most AFS utilize similar core components but employ diverse approaches, materials, and experimental conditions.

Establishment ofOrientia tsutsugamushiLc-1 (Rickettsiales: Rickettsiaceae) Infection in ICR Outbred Mice (Rodentia: Muridae) by Needle Challenge: Table 1. [PDF]

Journal of Medical Entomology, 2014
Orientia tsutsugamushi is a pathogen transmitted by Leptotrombidium that causes scrub typhus. To develop an infection mouse model, a mite-derived isolate of O. tsutsugamushi was established from a laboratory-maintained colony of Leptotrombidium chiangraiensis (O. tsutsugamushi Lc-1).

'Candidatus Tisiphia' is a widespread Rickettsiaceae symbiont in the mosquito Anopheles plumbeus (Diptera: Culicidae). [PDF]

Environ Microbiol, 2023
Control of mosquito populations and their vector competence is commonly achieved using symbionts, but efforts are hampered in anophelines by limited compatible symbiotic partners. We establish that the Rickettsiaceae symbiont, Ca. Tisiphia', resides in the ovaries of Anopheles plumbeus and infects >95% of German populations.

Rickettsiosis Infections in Sarawak: Epidemiological Insights and Public Health Strategies. [PDF]

Can J Infect Dis Med Microbiol
Rickettsiosis infections pose a significant public health concern in Sarawak, Malaysia. Despite their importance, these infections remain poorly recognised, under‐researched and inadequately documented within the context of the Sarawak region. This comprehensive evaluation seeks to address this knowledge gap by providing an in‐depth analysis of ...

Diversity of lice and flea- and lice-borne pathogens in free-ranging dogs in Uzbekistan. [PDF]

Med Vet Entomol
Lice (Trichodectes canis, Linognathus africanus and Bovicola bovis) and fleas were collected from dogs across five regions of Uzbekistan and subjected to molecular analysis. Molecular screening detected Dipylidium caninum and Bartonella spp. in fleas, while Rickettsia spp. were identified in both fleas and lice.
