| Neonatal diarrhea is one of the main causes of morbidity and mortality in piglets, and it leads to significant economic losses for pig farmers worldwide. The aim of this study was to determine the frequency of diagnosis, age group, and association of group A rotavirus (GARV) infection with diarrhea in piglets from pig herds in two (south and center-west)Brazilian geographical regions. The frequency of GARV diagnosis was evaluated between 2004 and 2007, using SS-PAGE on 681 fecal samples (428 diarrheic and 253 with normal consistency) from 1-4 week-old piglets. The animals were selected from 130 pig herds and 80 counties in the states of Rio Grande do Sul, Santa Catarina, Paraná, Mato Grosso do Sul, and Mato Grosso, Brazil. None of the herds were vaccinated... |

| Clostridium difficile has emerged as a major cause of neonatal colitis in piglets, displacing classic bacterial pathogens. However, there is no information regarding the distribution of this microorganism in pig farms in Brazil. In the present study, the presence of toxins A/B and of C. difficile strains in stool samples from 60 diarrheic or non-diarrheic newborn piglets (one to seven days old), from 15 different farms, was studied. The presence of toxins A/B was detected by ELISA and PCR was used to identify toxin A, toxin B and binary toxin gene in each isolated strain. C. difficile A/B toxins were detected in ten samples (16.7%). Of these, seven were from diarrheic and three were from non-diarrheic piglets. C. difficile was recovered from 12 out of 60... |
