Clinical Neurology and Neurosurgery, 1991
Case report of Mediterranean spotted fever in an 18 year old male heroin addict, caused by Rickettsia Conorii. The typical "tache noir" was absent. The patient developed meningoencephalitis within 5 days after onset of the systemic symptoms. Diagnosis was based on serological findings. Treatment with doxycycline led to rapid recovery without sequelae.

Antigenic Diversity of Rickettsia Conorii

The American Journal of Tropical Medicine and Hygiene, 1992
Analysis of seven strains designated as Rickettsia conorii for reactivity with a panel of 12 monoclonal antibodies to surface-protein epitopes of spotted fever group rickettsiae and by Western immunoblotting with standard serotyping sera revealed remarkable antigenic diversity.

Severe illness caused byRickettsia conorii

Annals of Tropical Paediatrics, 1993
An 18-month-old boy presented with a 5-day history of lethargy, fever, vomiting and rash. He required intensive care for inotropic and ventilatory support. He developed a disseminated intravascular coagulopathy and gangrene of his extremities. In addition, he had severe neurological dysfunction and loss of vision, both of which recovered spontaneously ...

Antibodies to Rickettsia conorii in dogs: Seasonal differences

European Journal of Epidemiology, 1993
Eight dogs, having showed positivity to Rickettsia conorii in serum samples obtained during the spring and summer, were studied again by means of a second determination during the next winter, 4-10 months later. Serum titer became negative in six dogs, persisted high in one, and fell from 1:640 to 1:40 in another dog.

Atypical Papulovesicular Rash Due to Infection with Rickettsia conorii [PDF]

Clinical Infectious Diseases, 1992
We present an unusual case of Rickettsia conorii infection that was associated with cutaneous papulovesicular lesions on a patient who had returned from the bushveld of South Africa. The lesions were diffusely scattered across the trunk, extremities, and both palms.

Encefalitis por Rickettsia conorii sin exantema

Revista de Neurología, 2002
Mediterranean boutonneuse fever, caused by Rickettsia conorii, is an endemic disease in the Mediterranean area. The serious forms of the disease, which include encephalitis, are infrequent but are associated with a high mortality rate. Diagnostic suspicion is backed up by the development of exanthema.

Expression of green fluorescent protein in Rickettsia conorii

Microbial Pathogenesis, 2002
Rickettsiae are obligate intracellular class III pathogens for which genetic manipulation has only recently been shown to be feasible. Such experiments were restricted to the typhus group rickettsiae, namely R. typhi and R. prowazekii. Here we report the first genetic manipulation of Rickettsia conorii, the bacterial agent responsible for the ...

Evolution, purification, and characterization of RC0497: a peptidoglycan amidase from the prototypical spotted fever species Rickettsia conorii

Biological chemistry, 2019
Rickettsial species have independently lost several genes owing to reductive evolution while retaining those predominantly implicated in virulence, survival, and biosynthetic pathways.
