Background: Salmonella enterica subsp. enterica serovar Brandenburg (antigenic formula 4,[5],12:l,v:e,n,z15) is a serovar of the O:4 (B) serogroup. In New Zealand, in 1996 S. Brandenburg emerged in the sheep population and caused a number of outbreaks. During these outbreaks in sheep, S. Brandenburg has caused abortion in pregnant ewes and has killed approx. the half of infected ewes. In addition, outbreaks in cattle have also been reported in New ZealandSerovar Brandenburg was first reported in 1930 in Germany. Serovar Brandenburg was reported among the 15th most common serovars in Europe. It is considered an occupational hazard, because farmers can acquire the disease by contact with infected animals. is reported among the 15th most common serovars in Europe. In New Zealand, in 1996, serovar Brandenburg emerged in the sheep population and caused a number of outbreaks.

Genetic characteristics:
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).

1 Brandenburg infection causes abortion in pregnant ewes and has killed approx. the half of infected ewes.
2 Brandenburg infection causes late-term abortions, sickness, and death in cattle, typically occurring during the late dry period (late winter/early spring). In naïve herds, first-calving heifers appear to be the most affected, with up to 35% experiencing abortions. During outbreaks, mortality rates can vary, averaging around 5%.
