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

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

Tick-borne rickettsioses, neglected emerging diseases in rural Senegal. [PDF]

PLoS Neglected Tropical Diseases, 2010
BACKGROUND: Rickettsioses are one of the most important causes of systemic febrile illness among travelers from developed countries, but little is known about their incidence in indigenous populations, especially in West Africa.

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 ...

Fatal Rickettsia conorii subsp. israelensis Infection, Israel

, 2008
Underdiagnosis of fatal spotted fever may be attributed to nonspecific clinical features and insensitive acute-phase serologic studies. We describe the importance of molecular and immunohistochemical methods in establishing the postmortem diagnosis of ...

TlyC, a conserved hemolysin in Rickettsia, contributes to spotted fever pathogenesis in mice

Microbiology Spectrum
Rickettsia circulates between mammalian hosts and hematophagous arthropod vectors by exploiting their intracellular environment. With advances in rickettsial genetic tools, recent studies have identified novel molecular mechanisms involved in Rickettsia ...

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.

Comparison of Hemostatic Activity in Canine Leukoreduced Cryoprecipitate, Cryopoor Plasma, and Fresh Plasma

Veterinary Clinical Pathology, Volume 54, Issue 2, Page 120-131, June 2025.
ABSTRACT Background To date, no studies have reported the evaluation of hemostatic activity in canine leukoreduced cryoprecipitate (LR‐CRYO) and leukoreduced cryopoor plasma (LR‐CPP). Objectives We aimed to compare the hemostatic activity of LR‐CRYO and LR‐CPP to leukoreduced fresh plasma (LR‐FP) and to evaluate the preservation of LR‐CRYO by ...
