The objective of this study was to determine the prevalence of Salmonella, Listeria monocytogenes, and fecal coliforms in bulk tank milk in the United States. As part of the NAHMS Dairy 2002 survey, 861 bulk tank milk samples were collected from farms in 21 states. Milk was directly plated on selective agars for direct bacterial enumeration and was enriched in selective broths to increase detec...

We used Salmonella enteritidis serotype dublin strain SL1438, a nonreverting, aromatic-dependent, histidine-requiring mutant, as a recipient for a recombinant plasmid coding for production of the nontoxic B subunit of the heat-labile Escherichia coli enterotoxin. The S. enteritidis derivative EL23 produced heat-labile enterotoxin subunit B that was indistinguishable from heat-labile enterotoxin...

This paper presents Salmonella data from animals, feedstuffs and feed mills in Sweden between 1993 and 1997. During that period, 555 isolates were recorded from animals, representing 87 serotypes. Ofthose, 30 serotypes were found in animals in Sweden for the first time. The majority of all isolates from animals were S. Typhimurium (n = 91), followed by S. Dublin (n = 82). There were 115 isolate...

In this study, primary and immortalized bovine intestinal epithelial cells (BIECs) were characterized for the expression of surface carbohydrate moieties. Primary BIEC-c4 showed staining greater than 90 % 16 lectins but less 50 four lectins. Immortalized BIECs significantly different lectin binding profile few compared to cells. studied infectivity E. coli, Salmonella enterica, rotavirus, coron...

AIMS To report the incidence of nontyphoidal salmonellas in England and Wales and identified in the Division of Enteric Pathogens, London between 1981 and 1990. METHODS Strains were serotyped and phage typed for Salmonella typhimurium, S enteritidis, and S virchow, using established methods. RESULTS Overall, less than 2% of nontyphoidal salmonellas isolated from humans were from blood cultu...
