Investigation of Anti‐IgG Antibody Responses to the 17‐kDa Outer Membrane Protein of Rickettsia japonica in Individuals From a High‐Risk Area for Japanese Spotted Fever

open access: yesExperimental Dermatology, Volume 34, Issue 7, July 2025.
ABSTRACT This study evaluated the seroprevalence and persistence of IgG antibodies against Rickettsia japonica's outer membrane protein (Omp) using a recombinant 17‐kDa antigen and Western blot analysis in residents of Minamiise, Japan—a high‐incidence Japanese spotted fever (JSF) area—and in individuals from non‐endemic regions.

Phosphatidylserine-binding receptor, CD300f, on macrophages mediates host invasion of pathogenic and non-pathogenic rickettsiae

open access: yesInfection and Immunity
Some arthropod-borne obligate intracellular rickettsiae are among the most virulent human pathogens. Rickettsia species modulate immune (e.g., macrophages; MΦ) and non-immune cell (e.g., endothelial cells) responses to create a habitable environment for ...

Flea-borne Rickettsioses: Ecologic Considerations

open access: yesEmerging Infectious Diseases, 1997
Ecologic and economic factors, as well as changes in human behavior, have resulted in the emergence of new and the reemergence of existing but forgotten infectious diseases during the past 20 years.

Development of Antisense Tools to Study Bodo saltans and Its Intracellular Symbiont

open access: yesMicrobiologyOpen, Volume 14, Issue 2, April 2025.
Obligate symbioses present challenges for functional genetic analysis. This study shows that antisense inhibition cannot be used to investigate gene functions in the aquatic symbiosis between Bodo saltans and its bacterial symbiont. Our work stresses the importance of the development of alternative protocols to study the biology of both the ...

Rickettsia typhi and Rickettsia felis in Xenopsylla cheopis and Leptopsylla segnis Parasitizing Rats in Cyprus [PDF]

open access: yesThe American Society of Tropical Medicine and Hygiene, 2010
Fleas collected from rats during a three-year period (2000–2003) in 51 areas of all provinces of Cyprus were tested by molecular analysis to characterize the prevalence and identity of fleaborne rickettsiae. Rickettsia typhi, the causative agent of murine typhus, was detected in Xenopsylla cheopis (4%) and in Leptopsylla segnis (6.6%). Rickettsia felis

Rickettsia felis Infection, Tunisia

open access: yesEmerging Infectious Diseases, 2006
We report, for the first time, serologic evidence of Rickettsia felis and R. aeschlimannii infections acquired in Tunisia from 1998 to 2003. We found that most patients with antibodies against both R. conorii and R.

Prolonged Fever in Children: An Inpatient Diagnostic Framework for Infections in Australia

open access: yesJournal of Paediatrics and Child Health, Volume 61, Issue 4, Page 532-539, April 2025.
ABSTRACT There are many causes of fever in children, ranging from common and self‐limiting to serious and life threatening. Careful assessment of children with prolonged fever without an obvious or identified source requires detailed history and examination with consideration of infections unique to the specific geographical region and individual ...

Rickettsial Infections and Fever, Vientiane, Laos

open access: yesEmerging Infectious Diseases, 2006
Rickettsial diseases have not been described previously from Laos, but in a prospective study, acute rickettsial infection was identified as the cause of fever in 115 (27%) of 427 adults with negative blood cultures admitted to Mahosot Hospital in ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.

Rickettsiosis Infections in Sarawak: Epidemiological Insights and Public Health Strategies

open access: yesCanadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Rickettsiosis infections pose a significant public health concern in Sarawak, Malaysia. Despite their importance, these infections remain poorly recognised, under‐researched and inadequately documented within the context of the Sarawak region. This comprehensive evaluation seeks to address this knowledge gap by providing an in‐depth analysis of ...
