NCBI PD link for serovar Corvallis: https://www.ncbi.nlm.nih.gov/pathogens/isolates/#(taxgroup_name:%22Salmonella%20enterica%22)%20AND%20computed_types:(%22serotype=Corvallis%22)

Genetic characteristics: Serovar Corvallis has been found to be polyphyletic with six lineages identified. By analyzing 388 Corvallis ST1541 isolates collected globally within a twenty-year period, Chen et al. found that the ST1541 strains carried ColRNA1 plasmids that contain qnr-like determinants. Their Bayesian analysis also inferred that the UK might be the origin of S. Corvallis strains currently prevailing in multiple regions. . Fischer et al. identified NDM-1 carbapenemase-producing Salmonella enterica subsp. enterica serovar Corvallis strains isolated from a wild bird in Germany. 

Animal reservoir: Serovar Corvallis was found to be associated with pigs in South-East Asia. This serovar was also isolated from chicken and dogs.
