Background Information¶

Salmonella enterica subsp. enterica serovar Bovismorbificans (antigenic formula 6,8,20:r,[i]:1,5) 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. M ultidrug-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).

Animal Reservoir¶

Pigs tend to be the main animal reservoir for serovar Bovismorbificans. This serovar was also found in cattle, chicken, sheep, and horses.

Geographical Distribution¶

Serovar Bovismorbificans has been found worldwide.

Human/Animal Outbreaks¶

There are multiple outbreaks associated with serovar Bovismorbificans. Here we reported a few as examples.

Year	Location	Associated source	Number of cases
2022	Greece	Tap water	33
2020	France	Dried pork sausages	33
2018	Netherlands	Raw, smoked, and Coburg ham	54
2016	Europe: multi-country	Uncooked ham products	63 (54 Dutch, 7 Belgian, 2 French cases)
2011	US: multistate	Tahini	9

Border Rejections¶

Multiple border rejections were found. Here we reported one as example.

Year	Exporting country	Importing country	Associated source	Product category
2021	Brazil	Germany	Black pepper¹	Herbs and spices

¹Both Salmonella Bovismorbificans and Salmonella II 42:r:- were found.

Recalls¶

Multiple recalls were reported. Here we selected one as example.

Year	Location	Recalled product	Type
2020	France	Dried pork sausages¹	Ready-to-eat meat product

¹ This recall was caused by a Bovismorbificans outbreak infecting 33 people. Three recalls of dried pork products were addressed in November 2020, influencing eight supermarkets.
