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 ...

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.

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

‘Candidatus Tisiphia’ is a widespread Rickettsiaceae symbiont in the mosquito Anopheles plumbeus (Diptera: Culicidae)

Environmental Microbiology, Volume 25, Issue 12, Page 3064-3074, December 2023., 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.

Positive associations matter: Microbial relationships drive tick microbiome composition

Molecular Ecology, Volume 32, Issue 14, Page 4078-4092, July 2023., 2023
Abstract Untangling how factors such as environment, host, associations among bacterial species and dispersal predict microbial composition is a fundamental challenge. In this study, we use complementary machine‐learning approaches to quantify the relative role of these factors in shaping microbiome variation of the blacklegged tick Ixodes scapularis ...

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.
