| egg penetration by campylobacter jejuni. | hens eggs were immersed in suspensions of campylobacter jejuni (4 strains) and examined for penetration and infection. penetration was demonstrated using an egg moulding technique and by culture. c. jejuni was recovered from shell membranes, but not from the albumin or yolk. embryonic deaths were not significantly greater in test than control eggs. unlike a strain of salmonella virchow, which was used as a control, the c. jejuni strains did not survive for more than 6 hours after penetration. it ... | 1985 | 18766924 |
| survey of the prevalence of salmonella on commercial broiler farms in the united kingdom, 2005/06. | between october 2005 and september 2006, all european union member states were required to carry out standardised surveys of the prevalence of salmonella in broiler flock holdings to establish baseline data from which to derive national targets for disease reduction. in the uk 382 holdings were sampled, 41 of which were positive for salmonella, giving an estimated weighted prevalence of 10.7 per cent (95 per cent confidence interval [ci] 8.1 to 13.1 per cent). the serotype most frequently isolat ... | 2008 | 19043089 |
| salmonella virchow: a cause of significant bloodstream invasion. | salmonella virchow, a food poisoning strain previously only sporadically responsible for disease, has recently been isolated with increasing frequency in scotland. the experience of infections due to this organism in 1980 in an infectious diseases unit is reported. nine of 15 patients consecutively admitted with infection due to this organism were found to be septicaemic on blood culture thus highlighting the invasive propensity of this serotype. | 1983 | 6867700 |
| salmonella sofia differs from other poultry-associated salmonella serovars with respect to cell surface hydrophobicity. | salmonella enterica is one of the most important foodborne pathogens. salmonella enterica subsp. ii 4,12:b:- (salmonella sofia) is commonly found in australian poultry. it has been suggested that physicochemical properties such as surface charge and hydrophobicity may affect bacterial attachment to surfaces and their ability to persist in food systems. a possible link between hydrophobicity cell surface charge and persistence of salmonella from the poultry system was examined. hydrophobicity of ... | 2008 | 19244894 |
