NCBI PD link for serovar Brandenburg: https://www.ncbi.nlm.nih.gov/pathogens/isolates/#(taxgroup_name:%22Salmonella%20enterica%22)%20AND%20computed_types:(%22serotype=Brandenburg%22)
Genetic characteristics: Siepker et al. studied Brandenburg isolates from two separate late-term abortion outbreaks in Jersey heifers and found all isolates were of ST type 873 and carried typhoid toxin genes, along with various fimbrial gene clusters, type III secretion system genes, and several pathogenicity islands. Out of 37 Brandenburg isolates collected in Spain, 21 of them exhibited resistance to one or more unrelated drugs, with the most common resistances being to streptomycin, tetracycline, kanamycin, chloramphenicol, ampicillin, and trimethoprim-sulfamethoxazole, encoded by the genes aadA1, tet(A) or tet(B), aphA1, catA1, blaTEM, and dfrA1-sul1-sul3, respectively.
Animal reservoir: Serovar Brandenburg was found in different animal species (pigs, turkey, cattle, horse, deer and sheep). However, in New Zealand, it was predominantly found in ruminants (sheep mostly).
