Epidemiology and clinical features of flea-borne rickettsioses

Revista Colombiana de Ciencias Pecuarias, 2017
Murine typhus is a flea-borne rickettsiosis caused by Rickettsia typhi. The disease is endemic to tropical and subtropical regions throughout the world. It is likely vastly under-recognized as a cause of febrile illness.

Case Report: Cardiovascular Manifestations due to Flea-Borne Typhus. [PDF]

Am J Trop Med Hyg
ABSTRACT. Flea-borne typhus is a vector-borne disease caused by Rickettsia typhi that occurs worldwide, except in Antarctica. In the United States, most cases are restricted to California, Hawaii, and Texas. The syndrome is characterized by nonspecific signs and symptoms: fever, headache, rash, arthralgia, cough, hepatosplenomegaly, diarrhea, and ...

Targeting surface cell antigen 2 increases sensitivity of Rickettsia typhi detection. [PDF]

PLoS Negl Trop Dis
BackgroundMurine typhus is a flea-borne disease caused by Rickettsia typhi that typically presents as an acute febrile illness. The diagnosis is often missed, leading to delays in appropriate treatment. A qPCR targeting a single gene (ompB) for R.

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

Am J Trop Med Hyg, 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.

Bayesian spatial modelling and the significance of agricultural land use to scrub typhus infection in Taiwan [PDF]

, 2013
Scrub typhus is transmitted by the larval stage of trombiculid mites. Environmental factors, including land cover and land use, are known to influence breeding and survival of trombiculid mites and, thus, also the spatial heterogeneity of scrub typhus ...

Improved Detection and Sequencing of Rickettsia spp. DNA in South African Wildlife. [PDF]

Vet Med Sci
Nested gltA PCR detected Rickettsia spp. DNA in 44% of South African wildlife samples previously negative by RLB, revealing spotted fever, typhus and transitional group lineages, novel host records, co‐infection and multi‐organ dissemination in impala, highlighting complex wildlife involvement and zoonotic risk within a One Health framework.

Delayed correlation between the incidence rate of indigenous murine typhus in humans and the seropositive rate of Rickettsia typhi infection in small mammals in Taiwan from 2007-2019.

PLoS Neglected Tropical Diseases, 2022
Murine typhus is a flea-borne zoonotic disease with acute febrile illness caused by Rickettsia typhi and is distributed widely throughout the world, particularly in port cities and coastal regions.
