Animal salmonelloses: a brief review of “host adaptation and host specificity” of Salmonella spp

Salmonella enterica, the most pathogenic species of the genus Salmonella, includes more than 2,500 serovars, many of which are of great veterinary and medical significance. The emergence of food-borne pathogens, such as Salmonella spp., has increased knowledge about the mechanisms helping microorganisms to persist and spread within new host populations. It has also increased information about t...

Salmonella, the host and disease: a brief review.

Salmonella species cause substantial morbidity, mortality and burden of disease globally. Infections with Salmonella species cause multiple clinical syndromes. Central to the pathophysiology of all human salmonelloses is the induction of a strong host innate immune/inflammatory response. Whether this ultimately reflects an adaptive advantage to the host or pathogen is not clear. However, it is ...

A new Salmonella typhimurium DNA host specificity.

The genetic properties of a new (hspS) host specificity of Salmonella typhimurium were investigated using bacteriophage L. Phage L is a better substrate for s-specific restriction than phage P22. Mutants deficient in s-restriction only were found at the same frequency as mutants deficient in both restriction and modification. Crosses between S. typhimurium Hfr and S. typhimurium For between Esc...

Salmonella Serovars and Their Host Specificity

Salmonella is a causative agent for a wide variety of pathological diseases in humans, cattle, poultry and other farm animals and hence Salmonella infections are a major cause of concern to humans, veterinary animals and to food industry. With characterization of over 2500 Salmonella serovars, the pathogen nearly infects all vertebrates but the severity of infection varies from one serovar to a...
