The bulk of the lactate dehydrogenase (LDH) that increases in the serum of mice infected with Mycobacterium lepraemurium (MLM) derives from the liver and corresponds to the isozyme V. MLM-induced granulomas continuously arise in the liver and steadily increase in size until the animal's death. Growing granulomas push the adjacent hepatocytes away and cause them to disrupt and to release their cytoplasmic contents, including LDH. The LDH is then picked up by the infiltrating phagocytes and/or admixed with the circulating blood. Other LDH-containing organs (including the testis with its additional isozyme LDH-X) in the infected or normal animals do not seem to significantly contribute to the serum levels of LDH. The study of the liver-associated histochemical and biochemical changes in this controlled model of murine leprosy allows us to gain insight into the overall pathology of this mycobacteriosis. In some respects this sheds light on the liver involvement in human leprosy; a subject on which results of all sorts have been published.
