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.

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.

[Possibilities of serological verification of siberian tick borne type with use of test system for identification of antibodies to Rickettsia conorii.]

Russian Clinical Laboratory Diagnostics, 2019
The real epidemiological impact of Spotted Fever Group rickettsioses including Siberian tick-borne typhus (STT) in Russia is not sufficiently studied. One of the reasons is the actual absence of either certified domestic diagnostic kits or the evidence ...

Atypical Papulovesicular Rash Due to Infection with Rickettsia conorii

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.

Rickettsiosis Caused by Rickettsia conorii in Uruguay

Annals of the New York Academy of Sciences, 2003
Abstract: 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.
