A cDNA clone, designated IL-8nL, was obtained by suppression subtractive hybridisation between lipopolysaccharide-stimulated and non-stimulated populations of the rainbow trout macrophage-like cell line, RTS11. IL-8nL was similar but not identical to a recently published sequence of the gene encoding rainbow trout interleukin-8 (IL-8). Amplification of genomic DNA by the polymerase chain reaction (genomic PCR) using a single outbred trout with common primers in the 5' and 3' untranslated regions gave six distinct genomic sequences, including one ( IL-8A) almost identical to that of the published IL-8 gene and another identical to IL-8nL. The other four clones were termed IL-8B, IL-8C, IL-8D and IL-8E. The deduced amino acid sequences of IL-8A through IL-8E are all identical to the published IL-8, while the IL-8nL protein has a substitution of Arg87 to Lys. Analysis of ten outbred trout by genomic PCR of a repeat region in exon 4, which has three different sizes in the above alleles, revealed a shorter, fourth fragment termed IL-8X and another of the same size as IL-8nL, but with a different single nucleotide replacement, called IL-8nL2. These results, together with a Southern blot of the same ten individuals showing up to five bands, indicate that rainbow trout has at least four copies of the IL-8 gene. Like IL-8nL, IL-8X lacks the repeat sequence in exon 4 and encodes a protein identical to IL-8nL protein. Polymerase chain reaction of the repeat region was useful for typing rainbow trout into four categories, and the type III and IV fish have a new allele, IL-8F, which lacks one repeat unit compared with IL-8A.
