| aeromonas hydrophila isolated from food and drinking water: hemagglutination, hemolysis, and cytotoxicity for a human intestinal cell line (ht-29). | aeromonas hydrophila isolated from food and drinking water was tested for pathogenicity by studying its hemolysis, hemagglutination, and cytotoxicity. hemolysis, tested on erythrocytes from six different species, was more frequently seen with water isolates (64%) than with food isolates (48%). hemagglutination was more frequently encountered with food isolates (92%) than with water isolates (73%). cytotoxicity, evaluated on seven cell lines, was frequently observed with food isolates (92%) and w ... | 1996 | 8795237 |
| high-performance liquid chromatography determination of residue levels on chicken carcasses treated with cetylpyridinium chloride. | cetylpyridinium chloride (cpc) has been found to be effective in reducing contamination of chicken carcasses from a variety of microorganisms, including escherichia coli o157:h7, salmonella typhimurium, campylobacter jejuni, aeromonas hydrophila, listeria monocytogenes, and staphylococcus aureus. a procedure has been developed to determine residue levels on chicken carcasses after cpc treatment. for the analysis, chicken carcasses were extracted with 95% ethanol. the cpc concentration in the ext ... | 1999 | 10406212 |
| molecular cloning of liver angiotensinogen gene in ayu (plecoglossus altivelis) and mrna expression changes upon aeromonas hydrophila infection. | angiotensinogen (agt) is thought to be an acute phase protein, because in mammals its plasma concentrations increase during inflammation induced by lipopolysaccharides (lps). a full-length cdna clone of the agt gene, 1828bp in size, was isolated from the fish ayu (plecoglossus altivelis). its deduced amino acid sequence of 462 residues had 57.7-68.6%, 30.2% and 23.3-27.4% identity to those sequenced from other fish, chicken and mammals, respectively. ayu-agt is most closely related to that of si ... | 2008 | 18337123 |
| distribution of mesophilic aeromonas species in raw and ready-to-eat fish and meat products in switzerland. | a total of 829 poultry, meat, shellfish and fish products commonly consumed in switzerland were qualitatively and quantitatively examined for the presence of mesophilic aeromonas spp. overall, aeromonads occurred in 24.1% of the samples. raw food products were frequently contaminated (e.g. 94.1% in minced meat), with colony counts up to 6.0 x 10(6)/g. some ready-to-eat products had a relatively high percentage of positive samples as well, such as cooked ham in slices (38.2%), mortadella (12.9%), ... | 1993 | 8268055 |
| multiplex pcr detection of enterotoxin genes in aeromonas spp. from suspect food samples in northern taiwan. | aeromonads possess an array of virulence factors and are causative agents of a number of human infections. among them, genes of one cytotoxic (act) and two cytotonic (alt, ast) enterotoxins are implicated in a human diarrheal disease. a rapid, specific, simultaneous detection of these enterotoxin genes in suspected food poisoning samples is not yet reported. hence, a multiplex pcr assay was designed to amplify the cytotoxic (act), heat-labile cytotonic (alt), and heat-stable cytotonic (ast) ente ... | 2008 | 18939759 |
