Background: Salmonella enterica subsp. enterica serovar Mbandaka (antigenic formula 6,7,14:z10:e,n,z15) is a serovar of the O:7(C1) serogroup. This serovar has been frequently isolated from poultry production environments. Salmonella ser. Mbandaka can be classified into two major groups. However, clustering of these groups and their subgroups were not associated with any patterns based on the host or geographical origin. A study found that all isolates contained a uniform virulence gene repertoire. This serovar is multi-drug resistant.
Animal reservoir: Serovar Mbandaka was primarily found in poultry. It has been reported from other animals (pigs, cattle, fish, wild birds, and canine).
Geographical distribution: Serovar Mbandaka has been found around world.
Outbreaks: Numerous outbreaks in different countries have been linked to Salmonella enterica subsp. enterica serovar Mbandaka, imported spices have been associated with several of these outbreaks.
