title: Detection of anthrax vaccine virulence factors by polymerase chain reaction.
abstract: In Italy, an attenuated Bacillus anthracis strain, named 'Carbosap', is used for immunization against ovine and bovine anthrax. Analysis on 'Carbosap', Sterne vaccine strain F34 and Pasteur vaccine strain SS104, were performed using primers specific for the sequences, encoding the toxic factors, located on plasmids pXO1 and pXO2 and primers specific for the chromosome. The results obtained from polymerase chain reaction (PCR) assay revealed the presence of both plasmids pXO1 and pXO2 in 'Carbosap' strain. This study showed that the 'Carbosap' vaccine strain has a different plasmid pattern in comparison to Pasteur vaccine strain SS104 and Sterne vaccine strain F34.
