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

Genetic Characteristics: Serovar Pomona has been found to be polyphyletic with two lineages identified. A study of of Salmonella in pets found some multi-drug resistant isolates of serovar Pomona in cats and turtles and 6 isolates from turtles that contained extended-spectrum beta-lactamase genes. A study of clinical and environmental serovar Pomona genomes found that many of the environmental strains had genes for the type 4 secretion system (T4SS) and identified genes associated with virulence factors such as fimbriae production and invasion regulation (invA, invB, invC, fimA, fimC, fimD, and fimF) from clinical and environmental samples.
