Abstract: Salmonella enterica serovar Berta (S. Berta) belongs to Salmonella serogroup D1 and has the antigenic formula O:1,9,12 H:f,g,t:-. It was firt reported in 1938 from pigs in Uruguay (Hormaeche et al. 1938). Since then, little attention has been paid to this serovar outside of America. in 1984, S. Berta was introduced to Denmark through imported parent stock chicken (Sorensen et al. 1991). It spread with surprising success through the broiler production system, and quickly became the third most common cause of human salmonellosis in Denmark (Olsen et al. 1992a). An erradication programme was initated, and by 1991, the broiler production system seems to be free from S. Berta. Figure 1 shows the annual number of isolations of S. Berta from flock of broilers and from human cases of salmonellosis in the period 1984 to 1991.

Ribosomal ribonucleic acid gene restriction patterns as potential taxonomic tools.
TL;DR: Sets of rDNA restriction fragment sizes might constitute useful data for inclusion in species and type strain descriptions and might later prove useful in identification of bacteria when biochemical characteristics are poor or atypical.

Typing of Salmonella species.
TL;DR: Epidemiological markers of strains of Salmonella are classified as major or minor, and patterns of resistance to antimicrobial agents, and restriction patterns of chromosomal and plasmid DNA are identified.

Biochemical and molecular characterization of Salmonella enterica serovar berta, and comparison of methods for typing.
TL;DR: Plasmid profiling in combination with restriction enzyme analysis of plasmids seemed to be the most rational typing strategy for S. berta, and strains regardless of geographical source or host are possibly clonal in nature.
Plasmid profiles as an epidemiological marker in Salmonella enterica serovar berta infections
TL;DR: Based on the results, indications are that broilers represent the main reservoir for human S. berta infections in Denmark.
