salmonella dublin infection in adult cattle: a slaughter house and knackery survey in south west wales.a survey was carried out between june 1970 and december 1971 in which gall bladders from cattle either slaughtered for food consumption or disposed of through knackeries were cultured for salmonellas. salmonella dublin was isolated from 28 of 1917 gall-bladders of adult cattle killed in the slaughterhouse at carmarthen, and from 23 of 197 gall-bladders obtained from adult cattle sent to a knackery at abergwili, near carmarthen. the results are compared with a similar survey carried out in 1947 a ...1977264496
the effect of storage in slurry on the virulence of salmonella dublin.the mouse was used as a model to determine whether storage of salmonella dublin in slurry and in broth reduces the virulence of the organism. no reduction in virulence of s. dublin stored in slurry for 36 days or in maintenance broth for 70 days was observed. the disease hazard involved in pasture-spreading of slurry contaminated with salmonellas is related to factors other than virulence.19751054060

an outbreak of salmonella dublin infection in england and wales associated with a soft unpasteurized cows' milk outbreak of salmonella dublin infection occurred in england and wales in october to december 1989. forty-two people were affected, mainly adults, and most lived in south-east england. microbiological and epidemiological investigations implicated an imported irish soft unpasteurized cows' milk cheese as the vehicle of infection. a case-control study showed a statistically significant association between infection and consumption of the suspect cheese (p = 0.001). salmonella dublin was subseque ...19921468523
a survey of antimicrobial resistance in salmonellae isolated from animals in england and wales during 1984-1987.resistance to 14 antimicrobial substances was tested in 18,647 salmonella strains isolated from animals, their environment and from animal feeds during the period 1984-1987. of the 2284 salmonella dublin strains the percentage sensitive to all the antimicrobial substances ranged from 18.1 to 26.8. resistance to the higher concentration of streptomycin (s25) ranged from 1.9 to 6.4%, whereas the corresponding figures when the lower concentration (s10) was used were 32.3 and 63.8%. resistance to th ...19911913133

genotype analysis of faecal and blood isolates of salmonella dublin from humans in england and analysis of genotype was made for representative strains of salmonella dublin. the collection consisted primarily of strains isolated from humans in england and wales, and were of both intestinal and extra-intestinal origin. three genetic elements were characterized by dna hybridization. they were the spvbc genes, extrachromosomal virulence determinants, the salmonella-specific insertion sequence is200, and the 16s ribosomal rna genes, a phylogenetic marker. two clones of s. dublin (sdri and ...19938097167
prevalence, incidence and geographical distribution of serovars of salmonella on dairy farms in england and wales.a study of randomly selected dairy farms in england and wales was made between october 1999 and february 2001 to estimate the prevalence and incidence of salmonella serovars. the farms were enrolled through five milk-buying companies, which represented 63 per cent of the dairy farms in england and wales, and they were sampled on up to four occasions (449 farms at visit 1, 272 farms at visit 2, 251 farms at visit 3 and 243 farms at visit 4). in total, 19,296 samples of pooled faecal pats and slur ...200516311384
