B) Depiction of the rpo132-ATI-p4c-A27 region in Cowpox virus Brighton Red (CPXV-BR) and VACV strains. Positions of primers RNApol, ATI-low, ATI-up, and P4c1 are illustrated. These primers have been used for the molecular diagnosis of Brazilian (BRZ)-VACV (5,26). The 300-bp fragment amplified by primers RNApol and P4c1 from GP1V and VBH was sequenced by Trindade et al. (9,13). Sequence outside this region is unknown. ATI-f is used to designate coding regions that resemble fragments of the wild-type (CPXV-BR) ATI gene. The gap in VACV-COP lies within the A26L gene. *This gene is often referred to as ATI due to its original description. However, the coding region is actually a fusion of the C-terminus of ATI and the N-terminus of P4c where the sequence in between has been deleted. The gene is currently identified by the Poxviridae Bioinformatics Resource (http://athena.bioc.uvic.ca/database.php?db=poxviridae) as belonging to the P4c precursor family. †Western Reserve is presumed similar in structure to SpAn232 virus, GP2V, ARAV, and PSTV due to similar restriction fragment length polymorphism results (6,7,11,13).
