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 ...

'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.

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.

'Candidatus Megaira polyxenophila' gen. nov., sp. nov.: considerations on evolutionary history, host range and shift of early divergent rickettsiae. [PDF]

PLoS ONE, 2013
"Neglected Rickettsiaceae" (i.e. those harboured by non-hematophagous eukaryotic hosts) display greater phylogenetic variability and more widespread dispersal than pathogenic ones; yet, the knowledge about their actual host range and host shift mechanism

Rickettsia vini n. sp. (Rickettsiaceae) infecting the tick Ixodes arboricola (Acari: Ixodidae) [PDF]

Parasites & Vectors, 2016
Recently, a new rickettsia named 'Candidatus Rickettsia vini' belonging to the spotted fever group has been molecularly detected in Ixodes arboricola ticks in Spain, the Czech Republic, Slovakia and Turkey, with prevalence reaching up to 100 %. The aim of this study was to isolate this rickettsia in pure culture, and to describe it as a new Rickettsia ...
