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 ...

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 ...

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.

Prevalence of antibodies to Rickettsia conorii, Rickettsia africae, Rickettsia typhi and Coxiella burnetii in Mauritania

European Journal of Epidemiology, 1998
Rickettsioses are caused by gram-negative, obligate intracellular bacteria of the family Rickettsiaceae. The presence of rickettsial diseases has been reported from throughout the African continent [1] and the need to define more precisely the epidemiology of rickettsiosis in Africa has been emphasized by the World Health Organisation [2]. In 1996, 118

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.

Pathogenesis of Cell Injury by Rickettsia conorii

1986
Abstract : This work was undertaken to determine the pathogenic mechanism by which Rickettsia conorii causes disease. R. conorii, an organism that has been neglected in spite of its widespread distribution and pathogenic qualities, was studied in human subjects, animal models, and in vitro.
