Comparative growth of spotted fever group Rickettsia spp. strains in Vero cells

Memorias do Instituto Oswaldo Cruz, 2016
In Brazil, the spotted fever group (SFG) Rickettsia rickettsii and Rickettsia parkeri related species are the etiological agents of spotted fever rickettsiosis. However, the SFG, Rickettsia rhipicephali, that infects humans, has never been reported.

Production and characterization of monoclonal antibodies to Rickettsia rickettsii [PDF]

Infection and Immunity, 1984
Five mouse ascitic fluids (MAFs) containing monoclonal antibody to Rickettsia rickettsii were produced from three original fusions by murine hybridoma technology. The five MAFs were fractionated and purified; each contained monoclonal antibody of the immunoglobulin G2a subclass.

Plaque Assay for Rickettsia rickettsii

Journal of Bacteriology, 1969
A plaque technique for the assay of Rickettsia rickettsii is described. The method employs primary chick or green monkey kidney monolayer cell cultures with either an agarose or special Noble agar overlay. Plaques were counted in 6 days and resultant titers correlated well with ld 50

Identification of novel surface-exposed proteins of Rickettsia rickettsii by affinity purification and proteomics. [PDF]

PLoS ONE, 2014
Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever, is the most pathogenic member among Rickettsia spp. Surface-exposed proteins (SEPs) of R. rickettsii may play important roles in its pathogenesis or immunity.

Serological evidence of Rickettsia in horses from a semi-arid Brazilian region

Revista Brasileira de Parasitologia Veterinária, 2021
Brazilian spotted fever (BSF) is a common tick-borne disease caused by Rickettsia rickettsii. Horses are the primary hosts of the main vector, Amblyomma sculptum, and are considered efficient sentinels for circulation of Rickettsia. Therefore, the aim of

Anti rickettsia-antibody for spotted fever group in horses and dogs in the North of Paraná Stated, Brazil [PDF]

, 2010
The Brazilian Spotted Fever (BSF) is a zoonosis that can be fatal if not trteated. As there are few studies of the BSF in the Paraná State, the occurrence of BSF was serologically investigated in dogs and horses by indirect immunofluorescence assay (IFA),
