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.

In vitro susceptibilities of Coxiella burnetii, Rickettsia rickettsii, and Rickettsia conorii to the fluoroquinolone sparfloxacin [PDF]

Antimicrobial Agents and Chemotherapy, 1991
In vitro susceptibilities of Rickettsia rickettsii, Rickettsia conorii, and Coxiella burnetii to the new fluoroquinolone sparfloxacin (AT-4140; RP 64206) were determined. Plaque and dye uptake assays were used to measure the MICs against R. rickettsii and R. conorii. The susceptibilities of C.

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 ...

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.

First case of Mediterranean spotted fever-associated rhabdomyolysis leading to fatal acute renal failure and encephalitis [PDF]

, 2014
Mediterranean spotted fever (MSF) is a tick-borne zoonosis caused by Rickettsia conorii. In Italy, about 400 cases are reported every year and nearly half of them occur in Sicily, which is one of the most endemic regions.

Rickettsia conorii Transcriptional Response within Inoculation Eschar

PLoS ONE, 2008
Rickettsia conorii, the causative agent of the Mediterranean spotted fever, is transmitted to humans by the bite of infected ticks Rhipicephalus sanguineus. The skin thus constitutes an important barrier for the entry and propagation of R. conorii. Given this, analysis of the survival strategies used by the bacterium within infected skin is critical ...

Diagnosis of a Rare Rickettsia felis Infection Complicated with Unusual Pericardial Effusion and Cardiac Tamponade Using an mNGS Test

Case Reports in Infectious Diseases, Volume 2024, Issue 1, 2024.
The occurrence of sporadic rickettsial infections has been consistently undervalued and overlooked, primarily owing to a limited emphasis on routine examinations for rickettsioses in clinical practice. At present, the immunofluorescence assay is the prevailing diagnostic method for suspected rickettsioses that enables the detection of specific ...
