| differential diagnosis of salmonella gallinarum and s. pullorum using pcr-relp. | salmonellosis in poultry of korea is a significant health problem, which causes substantial economic losses. the most common causative agents of chicken salmonellosis ar s. gallinarum and s. pullorum. traditional methods used to detect salmoenella spp. in chicken are tedious, time consuming and confer little guarantee of sensitivity and species specificity. therefore, a rapid and sensitive method for the differentiation of salmonella serogroup d was assessed. we first amplified the rfbs genes by ... | 2001 | 12441691 |
| comparison of intestinal invasion and macrophage response of salmonella gallinarum and other host-adapted salmonella enterica serovars in the avian host. | the purpose of this investigation was to study the host specific infection of salmonella gallinarum in chickens and to determine the contribution of intestinal invasion and macrophage survival in relation to systemic infection in the host. this was carried out by comparing the kinetics of infection of s. gallinarum to that of other salmonella host-adapted (s. cholerae-suis, s. dublin and s. typhimurium) and host-specific (s. pullorum and s. abortus-ovis) serovars. establishment of the rate of co ... | 2003 | 12488070 |

| [specified pathogen-free poultry flocks: the current situation]. | before the implementation of strategies to establish specified pathogen-free commercial poultry flocks, the ultimate goals need to be identified: 1) consumer protection by minimizing the risk for zoonotic diseases and food-borne pathogens, and/or 2) animal health protection against primary and secondary pathogens. the success for the establishment of specific pathogen-free poultry flocks depends on the biological characteristics, the epidemiological distribution and the transmission route of eac ... | 2005 | 16218186 |
| oral infection with the salmonella enterica serovar gallinarum 9r attenuated live vaccine as a model to characterise immunity to fowl typhoid in the chicken. | salmonella enterica serovar gallinarum (s. gallinarum) is the causative agent of fowl typhoid, a severe systemic disease of chickens that results in high mortality amongst infected flocks. due to its virulence, the immune response to s. gallinarum is poorly characterised. in this study we have utilised infection by the live attenuated s. gallinarum 9r vaccine strain in inbred chickens to characterise humoral, cellular and cytokine responses to systemic salmonellosis. | 2005 | 16221297 |
