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.

However, multidrug-resistant strains have been isolated from calves in Australia, showing resistance to ampicillin, sulfonamides, tetracycline, neomycin, kanamycin, sulfamethoxazole/trimethoprim, and streptomycin.
