Collection of 22 M. bovis isolates representative of the disease in GB with genotype and deletion analysis.

Analysis of bovine tuberculosis (bTB) genotype frequency (spoligotype and VNTR type) collated in isolates from the spoligotype database for 2006. The purpose of this collection was to generate a collection of isolates that represented the diversity of major genotypes in GB. The International Nomenclature for each spoligotype given by www.Mbovis.org (SBXXX), the VLA spoligotype and 6 locus VNTR call (e.g 17:7-5-5-5*-3-3.1), the raw frequency and percentage of the total for each genotype, the translated genotype name (ie 17:a, see APHA0126) as well as the identification code (AF number such as 61/0359/01) is shown. Subsequently, the representative isolates in the collection were analysed for the presence/absence of specific chromosomal deletions (RDX) that are used to identify sub-lineages of M. bovis.
