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

Somatic <I>Wolbachia</I> (Rickettsiales: Rickettsiaceae) Levels in <I>Culex quinquefasciatus</I> and <I>Culex pipiens</I> (Diptera: Culicidae) and Resistance to West Nile Virus Infection [PDF]

Journal of Medical Entomology, 2014
The endosymbiotic bacteria Wolbachia pipientis Hertig infects a wide variety of insect species and can increase viral resistance in its host. Wolbachia naturally infects Culex quinquefasciatus Say and Culex pipiens L. mosquitoes, both vectors of West Nile virus (WNV). We recently demonstrated that Wolbachia infection of Cx.

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 ...

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.

Established Population of the Gulf Coast Tick, Amblyomma maculatum (Acari: Ixodidae), Infected with Rickettsia parkeri (Rickettsiales: Rickettsiaceae), in Connecticut

Journal of Medical Entomology, 2021
Abstract We identified an established population of the Gulf Coast tick (Amblyomma maculatum Koch) infected with Rickettsia parkeri in Connecticut, representing the northernmost range limit of this medically relevant tick species. Our finding highlights the importance of tick surveillance and public health challenges posed by geographic ...

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 ...

A bacterial symbiont in the gill of the marine scallop Argopecten irradians irradians metabolizes dimethylsulfoniopropionate

mLife, Volume 2, Issue 2, Page 178-189, June 2023., 2023
Abstract Microbial lysis of dimethylsulfoniopropionate (DMSP) is a key step in marine organic sulfur cycling and has been recently demonstrated to play an important role in mediating interactions between bacteria, algae, and zooplankton. To date, microbes that have been found to lyse DMSP are largely confined to free‐living and surface‐attached ...
