Antibodies to Rickettsia conorii in dogs: Seasonal differences
European Journal of Epidemiology, 1993Eight 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, 2002Mediterranean 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, 2002Rickettsiae 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 ...

A total of 68 adult hard ticks were recovered from 5 cases of infestation involving pet rabbits (Oryctolagus cuniculus domesticus) in Malaysia. The ticks were later identified as the tropical brown dog tick, Rhipicephalus linnaei (Audouin, 1826 ...

Seroepidemical surveys concerning the prevalence of Rickettsia conorii and Rickettsia typhi have never been studied in northern Greece. We examined 1,584 sera samples from residents of northern Greece for the detection of antibodies to R. conorii and to R. typhi by means of immunofluorescence assay.

BACKGROUND: In total, 30 ixodid tick species were found on the Crimean Peninsula. Their epidemiological importance was directly correlated with the pathogenicity of the infectious agents that they may transmit.

Rickettsiosis Caused by Rickettsia conorii in Uruguay
Annals of the New York Academy of Sciences, 2003Abstract: The first three human cases of rickettsiosis caused by Rickettsia conorii in Montevideo, Uruguay were described in 1990. All of them showed an initial papulosquamous lesion on the scalp from a canine tick bite (Amblyomma triste). At the same time, fever and regional adenopathies were observed.
