Abducens nerve palsy and meningitis by Rickettsia typhi. [PDF]

Am J Trop Med Hyg, 2015
Patients with rickettsial infection may present with encephalitis or meningitis but neurologic involvement is rare in murine typhus. Here, we report two patients with Rickettsia typhi meningitis who presented with cranial neuropathy, presumably caused by two distinct disease processes.

Isolation of Rickettsia typhi from human, Mexico. [PDF]

Emerg Infect Dis, 2014
To the Editor: Murine typhus is a febrile illness caused by Rickettsia typhi. The clinical manifestations are nonspecific, and the signs and symptoms resemble those of several other febrile illnesses. Murine typhus can be a self-limiting infection; however, it should be diagnosed and treated because complications and even death can result (1).

Rickettsia-Macrophage Interactions: Host Cell Responses toRickettsia akariandRickettsia typhi [PDF]

Infection and Immunity, 2002
ABSTRACTThe existence of intracellular rickettsiae requires entry, survival, and replication in the eukaryotic host cells and exit to initiate new infection. While endothelial cells are the preferred target cells for most pathogenic rickettsiae, infection of monocytes/macrophages may also contribute to the establishment of rickettsial infection and ...

Serological evidence of exposure to Rickettsia felis and Rickettsia typhi in Australian veterinarians. [PDF]

Parasit Vectors, 2017
Rickettsia felis and Rickettsia typhi are emerging arthropod-borne zoonoses causing fever and flu-like symptoms. Seroprevalence and risk factors associated with exposure to these organisms was explored in Australian veterinarians.One hundred and thirty-one veterinarians from across Australia were recruited to participate in a cross-sectional survey ...

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.

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.
