| | Human Rotavirus Serotype G9, São Paulo, Brazil | CDC EID |
 | | G1 was the predominant serotype in these samples (294, 68.2%), followed by G9 (74, 17.2%), G4 (27, 6.3%), G2 (5, 1.2%), G3 (3, 0.7%), mixed infection (8, 1.8%), and untypeable (20, 4.6%) (Table 1). |
 | | The G9 type has been reported to be a common cause of diarrhea and has become the fifth most common serotype, which suggests that it may be a substantial cause of diarrhea in humans (5,6). |
 | | G9 strains have also been detected in animals (lambs and pigs [1]); detection of animal rotavirus provides evidence for natural human-animal genetic reassortment (30). |
