Item Clinical and laboratorial evidence of Rickettsia felis infections in Latin America.(2004) Galvão, Márcio Antônio Moreira; Mafra, Cláudio Lísias; Chamone, Chequer Buffe; Calic, Simone Berger; Zavala Velazquez, Jorge Ernesto; Walker, David HughesAfter the discovery and initial characterization of Rickettsia felis in 1992 by Azad and cols, and the subsequent first description of a human case of infection in 1994, there have been two communications of human rickettsiosis cases caused by Rickettsia felis in Latin America. The first one was published in 2000 by Zavala-Velazquez and cols in Mexico. In 2001 Raoult and cols described the occurrence of two human cases of Rickettsia felis rickettsiosis in Brazil.
