The HSP70 gene expression was determined in hepatopancreas, spleen, heart and head kidney in green swordtail Xiphophorus helleri challenged by Vibrio alginolyticus 0, 2, 5, 8 and 11 days after administration using RT-PCR. Results showed that tile gene expression of the HSP70 was of tissue specific.
