Serosurvey of Rickettsia typhi and Rickettsia felis in HIV‐infected patients [PDF]

Microbiology and Immunology, 2014
ABSTRACTConsistent with the effects of HIV on cell‐mediated immunity, an increased susceptibility to intracellular microorganisms has been observed. Rickettsiae are obligate intracellular microorganisms. The aim of this study was to examine Rickettsia typhi and Rickettsia felis infections in HIV+ population.

Metabolism of Rickettsia typhi and Rickettsia akari in Irradiated L Cells [PDF]

Infection and Immunity, 1972
L cells that had been exposed to 3,000 r of 60 Co the previous day were used to study the growth and metabolism of Rickettsia typhi and R. akari. Viable (unirradiated) L cells were used to study the effect of rickettsial infection on host-cell metabolism.

Complete Genome Sequence ofRickettsia typhiand Comparison with Sequences of Other Rickettsiae [PDF]

Journal of Bacteriology, 2004
ABSTRACTRickettsia typhi, the causative agent of murine typhus, is an obligate intracellular bacterium with a life cycle involving both vertebrate and invertebrate hosts. Here we present the complete genome sequence ofR. typhi(1,111,496 bp) and compare it to the two published rickettsial genome sequences:R. prowazekiiandR. conorii.

CD4+ T Cells Are as Protective as CD8+ T Cells against Rickettsia typhi Infection by Activating Macrophage Bactericidal Activity. [PDF]

PLoS Neglected Tropical Diseases, 2016
Rickettsia typhi is an intracellular bacterium that causes endemic typhus, a febrile disease that can be fatal due to complications including pneumonia, hepatitis and meningoencephalitis, the latter being a regular outcome in T and B cell-deficient C57BL/

Seroprevalence of Rickettsia typhi and Rickettsia felis in dogs from north-eastern Spain [PDF]

Clinical Microbiology and Infection, 2009
Rickettsia typhi is the aetiological agent of murine typhus (MT). This disease is often acute and mild, although some fatal cases have been observed [1]. In Spain, clinical cases and serological evidence of exposure to R. typhi in humans have been described [2,3]. In the past, MT has been associated with rodents and rat fleas.

Korat‐Scrub Typhus Score: A Clinical Tool for Predicting Scrub Typhus in Patients With Acute Undifferentiated Febrile Illness

Tropical Medicine &International Health, EarlyView.
ABSTRACT Objective Scrub typhus is a major cause of acute undifferentiated febrile illness (AUFI) in the Asia–Pacific region. Nonspecific presentation, limited diagnostic accuracy and delayed treatment increase morbidity and mortality. This study aimed to develop a simple clinical score for early diagnosis in adults with AUFI. Methods A cross‐sectional

Murine Typhus and Leptospirosis as Causes of Acute Undifferentiated Fever, Indonesia [PDF]

, 2009
To investigate rickettsioses and leptospirosis among urban residents of Semarang, Indonesia, we tested the blood of 137 patients with fever. Evidence of Rickettsia typhi, the agent of murine typhus, was found in 9 patients.
