[Epidemiological studies among Amerindians of Rondônia. IV. Serological survey for rotavirus among Suruí and Karitiána].

The authors present the results of a sero-epidemiological survey for rotavirus antibodies conducted among the Suruí and Karitiána, two amerindian groups of Rondônia, Brazilian Amazonia. The results indicate high percentages of seropositivity for both groups (67.8% among the Suruí and 77.4% among the Karitiána using ELISA and 45.5% for the Suruí and 56.7% for the Karitiána using indirect immunofluorescence). Chi square tests indicated no statistically significant association between group and seropositivity. The results are discussed in the light of other studies conducted among Brazilian amerindian groups.
