Risk1, a Phosphatidylinositol 3-Kinase Effector, Promotes Rickettsia typhi Intracellular Survival

open access: yesmBio, 2020
To establish a habitable intracellular niche, various pathogenic bacteria secrete effectors that target intracellular trafficking and modulate phosphoinositide (PI) metabolism.

Evaluation of the Widal tube agglutination test for the diagnosis of typhoid fever among children admitted to a rural hdospital in Tanzania and a comparison with previous studies. [PDF]

open access: yes, 2010
BACKGROUND: The diagnosis of typhoid fever is confirmed by culture of Salmonella enterica serotype Typhi (S. typhi). However, a more rapid, simpler, and cheaper diagnostic method would be very useful especially in developing countries.

Rickettsia typhi possesses phospholipase A2 enzymes that are involved in infection of host cells.

open access: yesPLoS Pathogens, 2013
The long-standing proposal that phospholipase A2 (PLA2) enzymes are involved in rickettsial infection of host cells has been given support by the recent characterization of a patatin phospholipase (Pat2) with PLA2 activity from the pathogens Rickettsia ...

Typhus Group Rickettsiosis, Germany, 2010–2017

open access: yesEmerging Infectious Diseases, 2018
Typhus group rickettsiosis is caused by the vectorborne bacteria Rickettsia typhi and R. prowazekii. R. typhi, which causes murine typhus, the less severe endemic form of typhus, is transmitted by fleas; R.

Surface proteome analysis and characterization of surface cell antigen (Sca) or autotransporter family of Rickettsia typhi. [PDF]

open access: yesPLoS Pathogens, 2012
Surface proteins of the obligate intracellular bacterium Rickettsia typhi, the agent of murine or endemic typhus fever, comprise an important interface for host-pathogen interactions including adherence, invasion and survival in the host cytoplasm.

Rickettsia typhi IN RODENTS AND R. felis IN FLEAS IN YUCATÁN AS A POSSIBLE CAUSAL AGENT OF UNDEFINED FEBRILE CASES [PDF]

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 2015
Rickettsia typhi is the causal agent of murine typhus; a worldwide zoonotic and vector-borne infectious disease, commonly associated with the presence of domestic and wild rodents. Human cases of murine typhus in the state of Yucatán are frequent. However, there is no evidence of the presence of Rickettsia typhi in mammals or vectors in Yucatán.

Use of TaqMan® real-time PCR for rapid detection of Salmonella enterica serovar Typhi [PDF]

open access: yes, 2014
We evaluated the performances of a newly designed real-time polymerase chain reaction (PCR) assay using TaqMan((R)) probes to detect Salmonella Typhi. TaqMan((R)) real-time PCR assays were performed by designed primers and probe based on the staG gene ...

Synthetic O‐Polysaccharide Backbone Units for a Single Antigen Vaccine Against Two Major Non‐Typhoidal Salmonella Serovars

open access: yesAngewandte Chemie, Volume 138, Issue 26, 22 June 2026.
A modular strategy was developed to synthesize tri‐, hexa‐, and nona‐saccharides representing repeating units of the conserved O‐polysaccharide backbone of Salmonella. Conjugates of these glycans to bacteriophage Qβ induced strong IgG responses in mice and rabbits. Antibodies elicited recognized native O‐polysaccharides and conferred protection against
