| spotted fever: epidemiology and vector-rickettsia-host relationship in rio de janeiro state. | the eco-epidemiological scenario of spotted fever (sf), a tick-borne disease that affects humans and other animals in several countries around the world, was analyzed in rio de janeiro (rj) state, brazil. during the last 34 years, 990 sf cases were reported in rj (the brazilian state with the highest population density), including 116 cases confirmed by serology (rifi) or pcr, among 42.39% of the municipalities with reported cases of sf. the epidemiologic dynamics of sf in rj state are very hete ... | 2017 | 28424664 |
| amblyomma sculptum: genetic diversity and rickettsias in the brazilian cerrado biome. | amblyomma sculptum (ixodida: ixodidae) berlese, 1888 is the most important tick vector in brazil, transmitting the bioagent of the most severe form of spotted fever (sf) in part of the cerrado (in the states of minas gerais and são paulo). in another part of the cerrado (central-west region of brazil), a milder form of sf has been recorded. however, neither the rickettsia nor the vector involved have been characterized. the aim of the current study was to analyse genetic variation and the presen ... | 2017 | 28752684 |
