1. Oral Administration of Citrus Extracts in Suckling Piglets
Abstract An experiment was conducted to evaluate the performance of suckling piglets subjected to oral administration of citrus extracts (CE). Twenty sows were used with ten sucking piglets on average initial weight of 1.26 kg (± 0.32) for 21 days. The experimental design was a randomized complete block design with two treatments: Negative Control (without

2. Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incidence (E1), organs relative weight, pH values, intestina

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. Rotavírus grupos A, B e C em leitões lactentes : frequência de diagnóstico e avaliação molecular de rotavírus atípicos
O Rotavírus é um dos principais agentes etiológicos das diarréias em leitões lactentes em todo o mundo. Devido à facilidade na identificação, com freqüência, apenas o grupo A de rotavírus é incluído nos estudos epidemiológicos da rotavirose em leitões. O objetivo desse estudo foi avaliar a freqüência de diagnóstico de rotavírus grupos A, B

6. Role of rotavirus (reo-like) in weanling diarrhea of pigs.
Piglets weaned abruptly and precociously at 3 weeks of age and placed in a crowded nursery commenced diarrhea 3 to 5 days later. Death losses were low (approximately 6%), but weight gain ceased for 2 weeks. Large numbers of rotavirus (reo-like) particles were seen by electron microscopy in diarrhetic fluids. Sections of intestines showed a loss of adsorptive

7. Cephamycin C Treatment of Induced Enterotoxigenic Colibacillosis (Scours) in Calves and Piglets
Cephamycin C is a β-lactam antibiotic that has broad gram-negative activity and is resistant to degradation by β-lactamases and safe for use in animals. In colostrum-fed calves infected with Escherichia coli strain B44, cephamycin C administered by gavage at 31.3 to 1,000 mg per calf (0.75 to 24 mg/kg) twice a day for 6 days starting at 20 h post-inoculati

8. Efficacy of Nitazoxanide against Cryptosporidium parvum in Cell Culture and in Animal Models
Nitazoxanide (NTZ), a drug currently being tested in human clinical trials for efficacy against chronic cryptosporidiosis, was assessed in cell culture and in two animal models. The inhibitory activity of NTZ was compared with that of paromomycin (PRM), a drug that is partially effective against Cryptosporidium parvum. A concentration of 10 μg of NTZ/ml (32

9. Reovirus-like agent associated with fatal diarrhea in neonatal pigs.
Large numbers of a reovirus-like agent were visualized with electron microscopy in bacteria-free gut homogenates obtained from piglets with a fatal diarrhea resembling transmissible gastroenteritis. The syndrome, of vomiting, diarrhea, dehydration, and death, was reproduced in piglets artificially infected with these bacteria-free gut homogenates. Reovirus-l

10. Studies with enteroaggregative Escherichia coli in the gnotobiotic piglet gastroenteritis model.
Two strains of enteroaggregative Escherichia coli of human origin fed to gnotobiotic piglets caused diarrhea or death in the majority of them. Histological examination revealed moderate hyperemia of the distal small intestine and cecum, swelling of small intestinal villi, and layers of aggregated bacteria stacked together in a mucus gel-like matrix overlying

11. K99 antigen-positive enterotoxigenic Escherichia coli from piglets with diarrhea in Sweden.
K88 antigen-negative enterotoxigenic Escherichia coli and non-enterotoxigenic strains isolated from piglets with diarrhea were examined for K99 antigen by agglutination tests after growth on Minca-IsoVitaleX (BBL Microbiology Systems, Cockeysville, Md.) agar medium. Of 64 K88-negative enterotoxigenic strains from as many piglets, 17 were found to be K99 posi

12. Conformity between heat-labile toxin genes from human and porcine enterotoxigenic Escherichia coli.
The genes encoding the heat-labile toxin of Escherichia coli were isolated by recombinant DNA methods from enterotoxigenic E. coli recovered from a human and a piglet with diarrhea. With restriction endonucleases, a fine-structure map was made for the toxin genes. Both genes were found to be highly homologous within the toxin-coding DNA, but the surrounding
