NCBI PD link for serovar Berta: https://www.ncbi.nlm.nih.gov/pathogens/isolates/#(taxgroup_name:%22Salmonella%20enterica%22)%20AND%20computed_types:(%22serotype=Berta%22)

Genetic characteristics: Serovar Berta has been found to be monophyletic. Olsen et al. concluded that strains of serovar Berta collected over a period of 6 years from a well documented natural outbreak in Denmark exhibited moderate to low virulence, with log VC₁₀ values ranging from 3.0 to 4.4 after intraperitoneal challenge in mice. Additionally, following an oral challenge, the maximum CFU in the internal organs of day-old chicks varied between 2 and 4 log₁₀ units.
