Transmission of Rickettsia conorii conorii in naturally infected Rhipicephalus sanguineus [PDF]

open access: bronzeClinical Microbiology and Infection, 2009
Rickettsia conorii conorii is the causative agent of Mediterranean spotted fever (MSF) a life-threatening zoonosis that is endemic in Mediterranean countries [1]. In the early 1930s, Olmer supposed that the vector of disease was the brown dog tick, Rhipicephalus sanguineus.

Rickettsia conorii O antigen is the target of bactericidal Weil-Felix antibodies. [PDF]

open access: yesProc Natl Acad Sci U S A, 2019
Significance Genetic analysis of Rickettsia has been difficult. We developed a transposon and selection scheme to facilitate the isolation of Rickettsia conorii mutants with insertional lesions. Here, we demonstrate that the R.

Acute disseminated encephalomyelitis due to Rickettsia conorii infection.

open access: yesSouth African Medical Journal, 2021
Acute disseminated encephalomyelitis (ADEM) is an immune-mediated acute inflammatory demyelinating disorder, which typically occurs after viral infections or immunisation. We present a case of a man with acute Rickettsia conorii infection whose diagnosis

Cutaneous-gangliar rickettsiosis due to Rickettsia conorii in Uruguay. [PDF]

open access: goldRevista do Instituto de Medicina Tropical de São Paulo, 1990
Se refieren 3 casos autóctonos de rickettsiosis cutáneo ganglionar trasmitidos por garrapatas de perros (Amblyomma maculatum, en uno de ellos) en el Uruguay. Dos de los 3 casos fueron seguramente provocados por Rickettsia conorii de acuerdo a los resultados de la reacción específica de inmunofluorescencia indirecta - IgM, anti R. conorii. Se incluye un

Facial nerve palsy associated with Rickettsia conorii infection [PDF]

open access: bronzeArchives of Disease in Childhood, 2001
Facial nerve palsy has been occasionally attributed to infectious agents, but Rickettsiae species have not been documented as causative agents. We report two adolescent girls with facial nerve palsy and serological evidence ofR conorii infection.

Molecular confirmation & characterization of Rickettsia conorii in north India: A report of three cases.

open access: yesIndian J Med Res, 2020
Background & objectives: In India, spotted fever group rickettsiae (SFGR) are an underdiagnosed cause of acute febrile illness (AFI). The non-specific Weil-Felix test is the first diagnostic modality for the diagnosis of SFGR in many laboratories due to ...

[A Rickettsia case caused by Rickettsia conorii].

open access: yesMikrobiyoloji Bulteni, 2018
Rickettsia species are gram-negative intracellular, small pleomorphic coccobacilli in the Rickettsiaceae family. This genus is serologically and genotypically divided into four groups as spotted fever group, typhus group, Rickettsia belli and Rickettsia ...

Global Transcriptomic Profiling of Pulmonary Gene Expression in an Experimental Murine Model of Rickettsia conorii Infection. [PDF]

open access: yesGenes (Basel), 2019
Mediterranean spotted fever develops from an infection with Rickettsia conorii, an obligate intracellular, Gram-negative, endotheliotropic, and tick-transmitted bacterial pathogen, and is an acute, febrile illness that can progress to life-threatening ...

TlyC, a conserved hemolysin in Rickettsia, contributes to spotted fever pathogenesis in mice [PDF]

open access: yesMicrobiology Spectrum
Rickettsia circulates between mammalian hosts and hematophagous arthropod vectors by exploiting their intracellular environment. With advances in rickettsial genetic tools, recent studies have identified novel molecular mechanisms involved in Rickettsia ...
