1. Óleo de arroz na alimentação de leitões recém-desmamados / Rice oil in weanling pig diet
A inclusão de óleos em dietas de leitões recém-desmamados tem por finalidade aumentar a densidade energética para atender às exigências energéticas dos leitões. Foram realizados dois experimentos para avaliar a inclusão do óleo semirrefinado de arroz como substituto ao óleo refinado de soja em dietas de leitões recém-desmamados. O Experimento 1

2. Detecção e caracterização molecular de sapovírus em suínos assintomáticos
Porcine sapovirus (PoSaVs) infections are frequent in pig herds in America, Europe and Asia. The infection can be symptomatic, in which the typical clinical signs is diarrhea. However, asymptomatic infections are described with relative frequency. The genetic diversity of the PoSaV is high. Five genogroups and 16 genotypes are well established and five genog

3. Genetic analysis of the porcine group B rotavirus NSP2 gene from wild-type Brazilian strains
Group B rotaviruses (RV-B) were first identified in piglet feces, being later associated with diarrhea in humans, cattle, lambs, and rats. In human beings, the virus was only described in China, India, and Bangladesh, especially infecting adults. Only a few studies concerning molecular analysis of the RV-B NSP2 gene have been conducted, and porcine RV-B has

4. Caracterização molecular de rotavírus genotipo P[6] de origem humana em um foco de diarreia neonatal suína
Neonatal diarrhea is the major piglet health problem in swine production systems worldwide.In intensive production the porcine serogroup A rotaviruses (PoRV-A) are common cause of diarrhea in suckling and recently weaned piglets. The VP4 and VP7 proteins of the outer layer viral capsid of RV-A are relevant for immunity against rotavirus infection by inducing

5. Determinação de rotavírus em suínos em uma granja do Rio Grande do Sul
Diarrhea, in newborn animals, is a morbid disease that exists worldwide; rotaviruses have been considered one of the main causes of gastroenteritis of viral origin, especially in countries where pig farming is intensively explored. The objective of this study was to extend the knowledge about the incidence of rotavirus in pigs, using the latex agglutination

6. Aditivos fitogênicos e butirato de sódio como potenciais promotores de crescimento de leitões recém-desmamados / Phytobiotic additives and sodium butyrate as potential growth promoters of weanling pigs
The antimicrobials growth promoters in the animal feed have been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate the effect of phytobiotic additives, sodium butyrate and even colistina o

7. Avaliação da utilização de anticorpos IgY de galinhas poedeiras no controle de diarréia pós desmame em leitões
Enterotoxigenic Escherichia coli (ETEC) is one of the most important causes of post-weaning diarrhea in piglets and causes economic losses in the pig industry. Alternatives methods in order to control this disease have been widely studied. Imunoprotection with antibodies from the egg yolk of hens (IgY) is an attractive alternative, taking into account the lo

8. Produção e avaliação de plasma bovino desidratado como ingrediente de rações de leitões desmamados precocemente. / Production and evaluation of plasma dehydrated as an ingredient in cattle rations of early weaners.
The objective of this work was to obtain spray dried bovine plasma (SDBP) and to compare it with a commercial one (CSDBP) as feed ingredients of weanling pigs (weaned at 21 days of age) based on performance, blood and plasma components, liver and spleen glutathione levels, small intestine morphology and diarrhea score. Blood of healthy bovines was collected

9. Parvovirus-like particles associated with diarrhea in unweaned piglets.
Numerous parvovirus-like particles, 18 to 26 nm in diameter, were detected by electron microscopy in the intestinal contents of two to three week old piglets with mild to severe diarrhea, in six Quebec pig herds. Hemagglutination of guinea pig and African green monkey red blood cells was obtained with clarified intestinal contents. Two isolates were found to

10. Prevalence of heat-stable II enterotoxigenic Escherichia coli in pigs, water, and people at farms in Thailand as determined by DNA hybridization.
The DNA hybridization assay employing a 460-base-pair fragment of DNA encoding for the methanol-insoluble form of heat-stable toxin (ST-II) was used to determine the prevalence of ST-II enterotoxigenic Escherichia coli (ETEC) in pigs, people, and water at 57 farms in Sri Racha, Thailand. ST-II ETEC was found in 62 (3%) of 2,110 suckling, 181 (32%) of 560 wea

11. Viral Determinants of Rotavirus Pathogenicity in Pigs: Evidence that the Fourth Gene of a Porcine Rotavirus Confers Diarrhea in the Homologous Host
A porcine rotavirus (prv) monoreassortant, S-F4, which carries RNA segment 4 of the pig-pathogenic variant prv 4F in the genetic background of the pig-apathogenic variant prv 4S (G. I. Tauscher and U. Desselberger, J. Virol. 71:853–857, 1997), was found to be pathogenic in gnotobiotic piglets. This indicates that RNA segment 4 of the pig-pathogenic variant

12. Adhesion of K88ab to guinea pig erythrocytes: effect on membrane enzyme activities.
Nontoxigenic Escherichia coli strains bearing K88 fimbriae have been associated with diarrhea in piglets. We have used guinea pig erythrocytes as a model of the host cell to study the cellular alterations after adherence of purified K88ab fimbriae. Although Mg2+-dependent ATPase was inhibited (up to 61%), Na/K ATPase was not. Metabolic enzymes were not signi
