N2 - In 1995, Edfors-Lilja and coworkers mapped the locus for the E. coli K88ab (F4ab) and K88ac (F4ac) intestinal receptor to pig chromosome 13 (SSC13). Using the same family material we have refined the map position to a region between the microsatellite markers Sw207 and Sw225. Primers from these markers were used to screen a pig BAC library and the positive clones were used for fluorescent in situ hybridization (FISH) analysis. The results of the FISH analysis helped to propose a candidate gene region in the SSC13q41→q44 interval. Shotgun sequencing of the FISH-mapped BAC clones revealed that the candidate region contains an evolutionary breakpoint between human and pig. In order to further characterise the rearrangements between SSC13 and human chromosome 3 (HSA3), detailed gene mapping of SSC13 was carried out. Based on this mapping data we have constructed a detailed comparative map between SSC13 and HSA3. Two candidate regions on human chromosome 3 have been identified that are likely to harbour the human homologue of the gene responsible for susceptibility towards E. coli F4ab/ac diarrhoea in pigs.
