'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.

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.

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 ...

Estimating scrub typhus and murine typhus incidence among adolescents and adults in Yangon, Myanmar. [PDF]

Trop Med Int Health
Abstract Objectives Rickettsioses are frequent causes of treatable febrile illness in Southeast Asia, including Myanmar. Accurate estimates of the incidence of rickettsioses are needed to inform investments in disease prevention and control. We sought to estimate the incidence of rickettsioses among adults and adolescents by combining sentinel hospital

Scrub Typhus Infection Precipitating Hemolysis in a Patient With G6PD Deficiency: A Case Report. [PDF]

Clin Case Rep
ABSTRACT Glucose‐6‐phosphate dehydrogenase (G6PD) deficiency is a well‐known red blood cell enzymopathy and a cause of intravascular hemolysis. This case report presents a child with underlying G6PD deficiency who experienced an acute episode of extensive intravascular hemolysis induced by a scrub typhus infection.

Impacts of Low Temperatures on Wolbachia (Rickettsiales: Rickettsiaceae)-Infected Aedes aegypti (Diptera: Culicidae)

Journal of Medical Entomology, 2020
AbstractIn recent decades, the occurrence and distribution of arboviral diseases transmitted by Aedes aegypti mosquitoes has increased. In a new control strategy, populations of mosquitoes infected with Wolbachia are being released to replace existing populations and suppress arboviral disease transmission.

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.

Cryptic Wolbachia (Rickettsiales: Rickettsiaceae) Detection and Prevalence in Culicoides (Diptera: Ceratopogonidae) Midge Populations in the United States

Journal of medical entomology, 2020
Culicoides midges vector numerous veterinary and human pathogens. Many of these diseases lack effective therapeutic treatments or vaccines to limit transmission. The only effective approach to limit disease transmission is vector control.

Exploring the Niche of Rickettsia montanensis (Rickettsiales: Rickettsiaceae) Infection of the American Dog Tick (Acari: Ixodidae), Using Multiple Species Distribution Model Approaches [PDF]

Journal of Medical Entomology, 2020
Abstract The 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.
