Rickettsia sibirica mongolitimonae infection, Sri Lanka

Journal of Infection in Developing Countries, 2017
Introduction. Rickettsia sibirica mongolitimonae was recently reported as a common rickettsiosis in France. Current serological evidence suggests the presence of scrub typhus and spotted fever group rickettsiosis in Sri Lanka.

Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Prevalence and risk factors for Q fever, spotted fever group rickettsioses, and typhus group rickettsioses in a pastoralist community of northern Tanzania, 2016–2017

Tropical Medicine &International Health, Volume 29, Issue 5, Page 365-376, May 2024.
Abstract Background In northern Tanzania, Q fever, spotted fever group (SFG) rickettsioses, and typhus group (TG) rickettsioses are common causes of febrile illness. We sought to describe the prevalence and risk factors for these zoonoses in a pastoralist community.

Tools and mechanisms of vacuolar escape leading to host egress in Legionella pneumophila infection: Emphasis on bacterial phospholipases

Molecular Microbiology, Volume 121, Issue 3, Page 368-384, March 2024.
Scheme of how secreted exit‐associated phospholipases are engaged by Legionella pneumophila during lytic escape. 1. L. pneumophila enters the host cell in an endocytic manner. 2. The bacterium actively establishes an intracellular niche (Legionella‐containing vacuole, LCV) which is required for replication.

A Protective Role of Canonical Wnt/β‐Catenin Pathway in Pathogenic Bacteria‐Induced Inflammatory Responses

Mediators of Inflammation, Volume 2024, Issue 1, 2024.
Inflammation is a complex host defensive response against various disease‐associated pathogens. A baseline extent of inflammation is supposed to be tightly associated with a sequence of immune‐modulated processes, resulting in the protection of the host organism against pathogen invasion; however, as a matter of fact is that an uncontrolled ...

Spotted fever group rickettsiae in ticks of migratory birds in Romania [PDF]

, 2016
BACKGROUND: Birds are important hosts and dispersers of parasitic arthropods and vector-borne zoonotic pathogens. Particularly migratory species may carry these parasites over long distances in short time periods.
