[use of semi-solid diasalm medium for isolation of salmonella enteritidis]. | the diagnostic semi-solid salmonella agar (diasalm) was compared with two commercial semi-solid rappaport-vasiliadis media (msrv by oxoid and srva, basis by himedia) using 52 strains of salmonella and 10 strains of interfering gram-negative bacteria. the diagnostic potency for salmonellae was higher in diasalm than in msrv or srva. unlike the rappaport-vasiliadis media, diasalm contains a diagnostic system consisting of lactose, saccharose and bromocresol purple, allowing the differentiation of ... | 1996 | 8966968 |
correlation of conversion of salmonella enterica serovar enteritidis phage type 1, 4, or 6 to phage type 7 with loss of lipopolysaccharide. | studies of pairs of salmonella enterica serovar enteritidis isolates from different poultry flocks showed that phage type (pt) 7 may be derived from pt 1, 4, and 6. the conversion appeared to be associated with loss of lipopolysaccharide. it is concluded that pt 7 may be of little value as an epidemiological marker of s. enterica serovar enteritidis. | 1997 | 8968942 |
plasmid characterization and pulsed-field electrophoretic analysis demonstrate that ampicillin-resistant strains of salmonella enteritidis phage type 6a are derived from salm. enteritidis phage type 4. | plasmid incompatibility studies have demonstrated that strains of salmonella enteritidis phage type (pt) 6a resistant to ampicillin possess a 36 megadalton incompatibility group (inc) x plasmid coding for resistance to ampicillin which is capable of converting strains of salm. enteritidis belonging to pts 1 and 4 to pt 6a, and pt 8 to pt 13. however, pulsed-field gel electrophoresis (pfge) has demonstrated that all clinical isolates of pt 6a have a characteristic xbai pulsed-field profile which ... | 1996 | 8972088 |
a rat model of infection by salmonella typhimurium or salm. enteritidis. | salmonellosis in the rat has many similarities with the disease in humans, with the ileum thought to be the main site of colonization/invasion in both species. thus, the rat may be a useful way to study the mechanism of infection by these pathogenic bacteria. a series of infection trials carried out with hooded lister rats showed that a salmonella infection persisted for an extended period of time and that salmonellae bind to the small intestinal epithelium as early as 4 h after intragastric int ... | 1996 | 8972092 |
intestinal colonization and organ invasion in chicks experimentally infected with salmonella enteritidis phage type 4 and other phage types isolated from poultry in the united states. | phage type 4 salmonella enteritidis strains have only recently been isolated from poultry and humans in the united states, although this phage type predominates in many other countries. the present study assessed the ability of s. enteritidis isolates of various phage types found in the united states (including phage type 4) to colonize the intestinal tract and invade to reach internal organs in experimentally infected chicks. groups of 5-day-old single-comb white leghorn chicks were inoculated ... | 1996 | 8980817 |
an epidemiological study of salmonella enteritidis by pulsed-field gel electrophoresis (pfge): several pfge patterns observed in isolates from a food poisoning outbreak. | an epidemiological analysis of salmonella enteritidis from a food poisoning was done using pulsed-field gel electrophoresis (pfge) of blni- or xbai-digested fragments of chromosomal dna of isolates. s. enteritidis isolates obtained from 19 patients had identical pfge patterns. therefore, a strain giving the same pattern was considered to be the causative agent of this outbreak. in addition, four isolates that had different blni-digested pfge patterns were obtained from three patients, suggesting ... | 1996 | 8985943 |
antagonistic effects of intestinal lactobacillus isolates on pathogens of chicken. | twelve lactobacillus strains isolated from chicken intestine, which demonstrated a strong and moderate capacity to adhere to the ileal epithelial cells in vitro, were used to investigate their inhibitory ability against five strains of salmonella, i.e. salmonella enteritidis 935/79, salm. pullorum, salm. typhimurium, salm. blockley and salm. enteritidis 94/448, and three serotypes of escherichia coli, viz. e. coli o1:k1, o2:k1 and o78:k80. the results showed that all the 12 lactobacillus isolate ... | 1996 | 8987444 |
