25. Characteristics of Yersinia intermedia-like bacteria isolated from patients with diarrhea in Nigeria.
Five Yersinia strains, biochemically mimicking Yersinia intermedia, were isolated from patients with acute diarrheal diseases seen at the University of Lagos (Nigeria) Teaching Hospital between October 1979 and September 1982. The five isolates utilized citrate as their source of carbon and fermented sucrose, L-rhamnose, and alpha-methyl-D-glucoside, but unl

26. Virulence factors in Escherichia coli strains isolated from Swedish piglets with diarrhea.
Parenteral vaccination of sows against Escherichia coli diarrhea in their newborn piglets has become more common during the last decade in Sweden, and the vaccination has generally had positive effects. For more than 20 years we have investigated E. coli strains isolated from piglets and weaned pigs with enteric disorders, noting the presence of O groups, en

27. Comparative Pathogenesis of Tissue Culture-Adapted and Wild-Type Cowden Porcine Enteric Calicivirus (PEC) in Gnotobiotic Pigs and Induction of Diarrhea by Intravenous Inoculation of Wild-Type PEC
Porcine enteric calicivirus (PEC/Cowden) causes diarrhea in pigs, grows in cell culture, and is morphologically and genetically similar to the Sapporo-like human caliciviruses. Genetic analysis revealed that the tissue culture-adapted (TC) Cowden PEC has one distant and three clustered amino acid substitutions in the capsid region and 2 amino acid changes in

28. Outbreak of keratoconjunctivitis due to Salmonella weltevreden in a guinea pig colony.
The purpose of this report is to demonstrate that the ability to produce keratoconjunctivitis (KC) is a property found in Salmonella weltevreden. This observation is contrary to previous reports that Salmonella spp. do not produce KC. An outbreak of KC due to S. weltevreden occurred in a guinea pig colony, and the animals carried the organism in the intestin

29. New fimbrial antigen F165 from Escherichia coli serogroup O115 strains isolated from piglets with diarrhea.
Sixteen strains of Escherichia coli serogroup O115 isolated from piglets with diarrhea were examined for mannose-sensitive or mannose-resistant hemagglutination (MSHA or MRHA, respectively) for the presence of fimbriae by electron microscopy and for enterotoxigenicity by the ligated gut loop technique in 10-day-old piglets. Four strains demonstrated MRHA of

30. Transmission of Campylobacter hyointestinalis from a Pig to a Human
We report on a case of human gastroenteritis caused by the pathogen Campylobacter hyointestinalis. Recurrent watery diarrhea and intermittent vomiting were the most significant symptoms of the previously healthy patient. Whole-cell protein electrophoresis and 16S rRNA gene sequencing were used to identify this Campylobacter species. Investigation of the pati

31. Cryptosporidium infection and diarrhea in rural and urban areas of Jiangsu, People's Republic of China.
Screening of infants and children under age 15 years for Cryptosporidium oocysts in their stools was carried out in the suburb of Xuzhou City and six rural areas of Jiangsu Province. The infection rate varied from 0.7 to 5.06%. Of the total of 5,089 children examined, 89 (1.75%) were oocyst positive. The incidence was evidently higher in the group of childre

32. Genotyping and Phenotyping of Beta2-Toxigenic Clostridium perfringens Fecal Isolates Associated with Gastrointestinal Diseases in Piglets
Although Clostridium perfringens is recognized as an important cause of clostridial enteric diseases, only limited knowledge exists concerning the association of particular C. perfringens toxinotypes (type A to E) with gastrointestinal (GI) diseases in domestic animals. Some C. perfringens isolates also produce the newly discovered beta2-toxin (CPB2). Recent

33. Inoculation of baboons and macaques with simian immunodeficiency virus/Mne, a primate lentivirus closely related to human immunodeficiency virus type 2.
A primate lymphotropic lentivirus was isolated on the human T-cell line HuT 78 after cocultivation of a lymph node from a pig-tailed macaque (Macaca nemestrina) that had died with malignant lymphoma. This isolate, originally designated M. nemestrina immunodeficiency virus (MnIV) and now classified as simian immunodeficiency virus (SIV/Mne), was inoculated in

34. Attaching and effacing activities of rabbit and human enteropathogenic Escherichia coli in pig and rabbit intestines.
Three strains of enteropathogenic Escherichia coli (EPEC), originally isolated from humans and previously shown to cause diarrhea in human volunteers by unknown mechanisms, and one rabbit EPEC strain were shown to attach intimately to and efface microvilli and cytoplasm from intestinal epithelial cells in both the pig and rabbit intestine. The attaching and

35. Porcine rotavirus-like virus (group B rotavirus): characterization and pathogenicity for gnotobiotic pigs.
A rotavirus-like virus (RVLV) was isolated from a diarrheic pig from an Ohio swine herd. This virus infected villous enterocytes throughout the small intestine of gnotobiotic pigs and induced an acute, transitory diarrhea. Complete virions were rarely observed in the intestinal contents of infected animals; the predominant particle detected by immune electro

36. The effect of adoptive transfer of mononuclear leukocytes from an adult donor on spontaneous cell-mediated cytotoxicity and resistance to transmissible gastroenteritis in neonatal piglets.
The purpose of this study was to attempt to establish spontaneous cell-mediated cytotoxicity effector activity in the intraepithelial lymphocytes of neonatal piglets by adoptive transfer of mononuclear leukocytes from an adult donor and to determine the effect of transfer on the resistance of piglets to transmissible gastroenteritis. Cytotoxicity was determi
