Invasiveness and persistence of Salmonella enteritidis, Salmonella typhimurium, and a genetically defined S. enteritidis aroA strain in young chickens.
Newly hatched chicks were dosed orally with a Salmonella typhimurium wild-type strain, an S. enteritidis wild-type strain, and a genetically defined S. enteritidis aroA vaccine candidate, strain CVL30. The S. typhimurium strain, 2391 Nalr, was virulent in newly hatched chicks and caused deaths in 7 of 20 chicks after an oral dose of 10(5) organisms. The S. enteritidis wild-type strain, LA5, cau...
متن کاملSalmonella typhimurium and Salmonella enteritidis strains
Salmonella is a facultative intracellular pathogen that causes a variety of infectious diseases. The most common of such diseases is gastroenteritis, with bacterial multiplication in intestinal submucosae and diarrhea, caused by the inflammatory response and perhaps also by toxins. In specific hosts, adapted salmonellae produce systemic diseases such as typhoid and paratyphoid fevers in humans....
متن کاملIsolation and Detection of Virulence factors of Salmonella typhimurium and Salmonella enteritidis
Plasmids play an important role in the virulence and antibiotic resistance of Salmonella. Salmonella carry plasmids having different size and number. Plasmid profile analysis of single isolates of Salmonella typhimurium and Salmonella enteritidis revealed the presence of 4- plasmid profiles. Salmonella serovars produce several Type III secretions including Sop-E and Sop –B. Soap E is detected b...
متن کاملSelection of DNA aptamers to Salmonella Enteritidis and Salmonella Typhimurium
Aptamers are single stranded oligonucleotides that forms 3 dimensional structure and binds to target with high affinity and specificity. The target that aptamers can bind to is vast. In this project, the aptamers selected for two serotypes of Salmonella bacteria that are causes a widespread of food borne illness (Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST)). These aptamers were ...
متن کاملProtection Against Salmonella Typhimurium, Salmonella Gallinarum, and Salmonella Enteritidis Infection in Layer Chickens Conferred by a Live Attenuated Salmonella Typhimurium Strain
In the present study, we investigated the protection conferred by a live attenuated Salmonella enterica serovar Typhimurium (ST) strain against Salmonella Typhimurium, Salmonella Gallinarum (SG), and Salmonella Enteritidis (SE) infection in layer chickens. Birds were orally primed with the attenuated ST strain at 7 days of age and then boosted at 4 weeks post prime immunization (PPI). Sequentia...
