Amblyomma imitatorTicks as Vectors ofRickettsia rickettsii, Mexico

Emerging Infectious Diseases, 2010
Real-time PCR of Amblyomma imitator tick egg masses obtained in Nuevo Leon State, Mexico, identified a Rickettsia species. Sequence analyses of 17-kD common antigen and outer membrane protein A and B gene fragments showed to it to be R. rickettsii, which suggested a potential new vector for this bacterium.

Study of infection by Rickettsiae of the spotted fever group in humans and ticks in an urban park located in the City of Londrina, State of Paraná, Brazil Estudo da infecção por Rickettsias do grupo da febre maculosa em humanos e carrapatos de um parque urbano na Cidade de Londrina, Estado do Paraná

Revista da Sociedade Brasileira de Medicina Tropical, 2011
INTRODUCTION: Spotted fevers are emerging zoonoses caused by Rickettsia species in the spotted fever group (SFG). Rickettsia rickettsii is the main etiologic agent of Brazilian spotted fever (BSF) and it is transmitted by Amblyomma spp. ticks.

A ocorrência de riquetsioses do grupo Rickettsia rickettsii Occurrence of rickettsiosis of the group Rickettsia rickettsii

Revista de Saúde Pública, 1983
Foi realizada revisão da literatura com objetivo de atualizar as informações sobre a ocorrência de riquetsioses do grupo Rickettsia rickettsii. Verificou-se que nos EUA e Europa, a incidência da febre maculosa, vem aumentando desde 1970 até hoje. No Brasil, foi relatado um caso presuntivo, no estado da Bahia, em 1979.

Experimental Infection ofAmblyomma aureolatumTicks withRickettsia rickettsii

Emerging Infectious Diseases, 2011
We experimentally infected Amblyomma aureolatum ticks with the bacterium Rickettsia rickettsii, the etiologic agent of Rocky Mountain spotted fever (RMSF). These ticks are a vector for RMSF in Brazil. R. rickettsii was efficiently conserved by both transstadial maintenance and vertical (transovarial) transmission to 100% of the ticks through 4 ...
