Background: Salmonella enterica subsp. enterica serovar Bovismorbificans (antigenic formula 6,8,20:r,[i,]:1,5 [R1...]) is a serovar of the O:8 (C₂-C₃) serogroup. Serovar Bovismorbificans was first reported in grey seals in the UK in 1979. The prevalence of this serovar is generally low. For example, between three and fourteen cases of serovar Bovismorbificans occur annually in the Netherlands.

Genetic characteristics: Serovar Bovismorbificans has been found to be polyphyletic with three lineages identified and one stand-alone singleton that doesn't cluster with any other Salmonella Bovismorbificans isolates. Multidrug-resistant strains have been isolated from calves in Australia, showing resistance to ampicillin, sulfonamides, tetracycline, neomycin, kanamycin, sulfamethoxazole/trimethoprim, and streptomycin. Li et al. isolated two foodborne Bovismorbificans isolates of different origins in China, co-resistant to CIP and CTX, which harbored the same novel IncHI2-ST2 type conjugative plasmid. Gopinath et al. identified two polyphyletic clusters, comprising four STs (2640, 142, 1499, and 377).
