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

Genetic Characteristics: Serovar Schwarzengrund has been found to be polyphyletic with four lineages identified and one stand-alone singleton that does not cluster with any other Salmonella Schwarzengrund isolates. A study of antimicrobial resistance in global Salmonella isolates found that serovar Schwarzengrund was positively correlated with fluoroquinolone resistance. In addition, fluoroquinolone resistant strains have been linked to imported food in the US. Multidrug resistant (MDR) strains (e.g., resistant to dihydrostreptomycin, kanamycin, oxytetracycline, bicozamycin, trimethoprim, and sulfadimethoxine) have been linked to broilers in Japan. MDR S. Schwarzengrund was found to be transmitted from chickens to people in some countries in Asia. A serovar Schwarzengrund isolate was found to carry some markers of the plasmid to Emergent Salmonella Infantis (pESI).
