Foram isoladas 48 amostras de Arcobacter spp de 37 carcaças de frangos colhidas em frigorífico, prontas para consumo, entre 80 carcaças examinadas. Foram feitas tentativas de cultivo a partir de pele e de músculo, sendo obtidas 25 cultivos positivos de músculo e 23 de pele. As bactérias foram classificadas pelas características fenotípicas e pelo teste de PCR e PCR múltiplo, obtendo-se 41 amostras classificadas como Arcobacter butzleri e 07 com classificação a nível de gênero Arcobacter sp. Estes são os primeiros relatos sobre a ocorrência das bactérias em carcaças de animais no Brasil.

Fourty eight isolates of Arcobacter spp were obtained from 37 poultry carcasses, from abattoir, among 80 carcasses examined. Attempts for culturing were made from the skin and muscle, resulting on 25 positive cultures from muscle and 23 from skin. Classification was achieved by phenotypic characterization and PCR and multiplex PCR, resulting 41 samples of Arcobacter butzleri and 07 Arcobacter sp. This is the first report on the occurrence of Arcobacter in animal carcasses in Brazil.

Summary Faecal material from children aged zero to 5 years old with diagnosed GEA at one hospital in Manaus was studied through electron microscopy and enzime immunoassay. Samples were collected before any medical treatment was to be applied at the hospital. Out of 29 cases studied 12 showed positivity for rotavirus (41,4%). Out of the 29 cases studied 48,3% were treated with isolated rehydration, 31,0% with antibiotic therapy and 20,7% with chemotherapy. Out of the 12 positive cases 3 were treated with antibiotics and 3 with chemotherapy. Greater frequency of rotavirus was found to occur between zero to 12 months old children. Within this range of age the greater number of GEA and rotavirus cases was detected between the 7th and the 12th month.
