Abstract: According to the gene sequences in GenBank of Haplosporidium sp, a pair of specific primers were designed for amplifying the specific fragments of Haplosporidium sp. The reaction parameters were optimized to develop the polymerase chain reaction method for detection of Haplosporidium sp. The 244 bp long specific DNA fragment of Haplosporidium sp was amplified, but not from other pathogenic such as Perkinsus sp, Marteilia refringens, Aeromonas hydrophila, Pseudomonas fluorescens, Vibrio parahaemolyticu, Vibrio Alginolyticu, Vibrio Fluvialis and Vibrio Mimicus by PCR. The sensitivity results showed that as little as 100 fg DNA of Haplosporidium sp was detected by this PCR.
