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.

Detekcija IgG protutijela na Rickettsia typhi

Infektološki glasnik, 2020
Background. Rickettsia typhi belongs to the typhus group of rickettsiae and causes endemic typhus. Cases of endemic typhus and seropositivity to R. typhi have been reported in the neighbouring China and Russia. However, little is known of the endemic typhus in Kazakhstan.

Structural features of lipid A of Rickettsia typhi

Acta Virologica, 2011
Lipid A isolated from the Rickettsia typhi lipopolysaccharide (LPS) was investigated for its composition and structure using chemical analyses, gas chromatography-mass spectrometry (GC-MS), and electrospray ionization (ESI) combined with the tandem mass spectrometry (MS/MS).

Enzymatic activities of cell-free extracts of Rickettsia typhi [PDF]

Infection and Immunity, 1976
Cell-free extracts of Rickettsia typhi were tested for activities of enzymes of the tricarboxylic acid cycle, of glutamate catabolism, and of glycolysis. The organisms were grown in the yolk sacs of chicken embryos, harvested shortly before the time of embryo death, purified by Renografin density gradient centrifugation, and ruptured in a French ...

Persisting Rickettsia typhi Causes Fatal Central Nervous System Inflammation [PDF]

Infection and Immunity, 2016
ABSTRACTRickettsioses are emerging febrile diseases caused by obligate intracellular bacteria belonging to the familyRickettsiaceae. Rickettsia typhibelongs to the typhus group (TG) of this family and is the causative agent of endemic typhus, a disease that can be fatal. In the present study, we analyzed the course ofR. typhiinfection in C57BL/6 RAG1−/−

Serosurveillance of Orientia tsutsugamushi and Rickettsia typhi in Bangladesh [PDF]

The American Society of Tropical Medicine and Hygiene, 2014
Scrub and murine typhus infections are under-diagnosed causes of febrile illness across the tropics, and it is not known how common they are in Bangladesh. We conducted a prospective seroepidemiologic survey across six major teaching hospitals in Bangladesh by using an IgM enzyme-linked immunosorbent assay.

Molecular Detection of Rickettsia typhi in Cats and Fleas

PLoS ONE, 2013
Rickettsiatyphi is the etiological agent of murine typhus (MT), a disease transmitted by two cycles: rat-flea-rat, and peridomestic cycle. Murine typhus is often misdiagnosed and underreported. A correct diagnosis is important because MT can cause severe illness and death. Our previous seroprevalence results pointed to presence of human R.

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

Journal 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 ...

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.
