The authors present the results of a sero-epidemiological survey for rotavirus antibodies conducted among the Suruí and Kantiána, two amerindian groups of Rondônia, Brazilian Amazonia. The results indicate high percentages of seropositivity for both groups (67.8% among the Surui and 77.4% among the Kantiana 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.
