The Paucity of Typical Pathology: An Autopsy Series of Typhus Group Rickettsiosis-Associated Hemophagocytic Lymphohistiocytosis [PDF]

Pathogens
Murine typhus (also called flea-borne or endemic typhus) is an undifferentiated febrile illness caused by the bacterium Rickettsia typhi. The disease, transmitted by rat and cat fleas, is endemic to seaboard regions worldwide. Recently, murine typhus has

Rickettsiosis Infections in Sarawak: Epidemiological Insights and Public Health Strategies [PDF]

Canadian 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 ...

The First Report on Cat Flea (Ctenocephalides felis), a Zoonotic Haematophagous Insect Infestation in Humans in Bangladesh: A Case Report and Literature Review [PDF]

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
An 18‐year‐old girl who didn't have any pets but was infested with fleas from a pet‐owning neighbour. Flea‐bite dermatitis caused severe pruritus, urticarial and papulomatous lesions on the neck and arm. Fleas were removed and identified as Ctenocephalides felis, the cat flea.

Bayesian population‐based assessment of ascertainment bias in flea‐borne typhus surveillance in California, 2011–2019 [PDF]

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 765-775, December 2025.
Although flea‐borne typhus is historically associated with poorer living conditions, FBT surveillance reporting is associated with greater socioeconomic advantage at the population level. FBT surveillance may be biased towards socioeconomic advantage in its ascertainment of surveillance data.

Case Report: Early Doxycycline Therapy for Potential Rickettsiosis in Critically Ill Patients in Flea-Borne Typhus-Endemic Areas

The American Journal of Tropical Medicine and Hygiene, 2019
Flea-borne typhus (FBT), although usually perceived as a self-resolving febrile illness, actually encompasses a wide spectrum of disease severity, including fulminant sepsis with multi-organ failure. In endemic Texas and California, the incidence of FBT has more than doubled over the last decade.
