Prevalence and risk factors for murine typhus, scrub typhus and spotted fever group rickettsioses among adolescent and adult patients presenting to Yangon General Hospital, Yangon, Myanmar

Tropical Medicine &International Health, Volume 30, Issue 9, Page 966-977, September 2025.
Abstract Objectives To inform patient management and disease prevention, we sought to estimate the prevalence of, and identify risk factors for, scrub typhus, murine typhus, and spotted fever group rickettsioses (SFGR) among febrile patients presenting to hospital in Myanmar.

Facial nerve palsy associated with Rickettsia conorii infection [PDF]

Archives of Disease in Childhood, 2001
Facial nerve palsy has been occasionally attributed to infectious agents, but Rickettsiae species have not been documented as causative agents. We report two adolescent girls with facial nerve palsy and serological evidence ofR conorii infection.

Estimating scrub typhus and murine typhus incidence among adolescents and adults in Yangon, Myanmar

Tropical Medicine &International Health, Volume 30, Issue 9, Page 978-986, September 2025.
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

Serological Survey on the Occurrence of Rickettsia spp., Neospora caninum, Bartonella henselae and Toxoplasma gondii in Cats from Tuscany (Central Italy)

Animals, 2021
Asymptomatic cats often harbor pathogens, some of which have not been largely investigated in feline populations. The aim of this study was to evaluate the occurrence of antibodies against Rickettsia conorii, Rickettsia felis, Rickettsia typhi, Neospora ...

Legionella pneumophila modulates the host cytoskeleton by an effector of transglutaminase activity

mLife, Volume 4, Issue 3, Page 232-248, June 2025.
Abstract The bacterial pathogen Legionella pneumophila delivers more than 330 effector proteins into host cells through its Dot/Icm type IV secretion system (T4SS) to facilitate its intracellular replication. A number of these effectors modulate organelle trafficking pathways to create a membrane‐bound niche called the Legionella‐containing vacuole ...

One Health Approach to Rickettsiosis: A Five-Year Study on Spotted Fever Group Rickettsiae in Ticks Collected from Humans, Animals and Environment

Microorganisms, 2021
The spotted fever group of Rickettsiae is a heterogeneous group of Rickettsiae transmitted by ticks, causing similar diseases in humans (spotted fever). Until recently, it was supposed that a single pathogenic tick-borne SFG Rickettsia circulated in each

Evaluation of a new serological test for the detection of anti-Coxiella and anti-Rickettsia antibodies. [PDF]

, 2015
Coxiella burnetii and members of the genus Rickettsia are obligate intracellular bacteria. Since cultivation of these organisms requires dedicated techniques, their diagnosis usually relies on serological or molecular biology methods.
