The transmission electron microscopic (TEM) studies of the human leprosy derived chemoautotrophic nocardio-form (CAN) bacteria and EUS derived CAN bacteria showed presence of double contoured cell-walls consisting of an electron transparent and a dense layer. The fibrillar structures on the surface of these CAN bacterial cells also suggested their similarity to the human tissue derived Mycobacterium leprae cells. These EM studies further revealed mycelial and coccoid bodies in all these bacteria as was observed originally.

Chemoautotrophic nocardioform (CAN) bacteria had been repeatedly isolated from fish with ulcerative disease syndromes (EUS) from the massive epizootics that had repeatedly occurred since 1988 in eastern India as the major or only pathogenic agent in the background of distinctive environmental and epizootic data. Since these isolates bear significant similarity to the human and rat leprosy bacilli, attempts had been made to demonstrate the pathogenicity of this fish pathogen in the "Swiss" strain of mice as a convenient model. The studies reveal that the fish CAN bacteria could produce pathogenic effects in mice similar to that of the rat leprosy bacillus.

Nocardioform actinomycetic organisms were present regularly in, and isolated repeatedly from, different varieties of fish affected with epizootic ulcerative syndrome lesions of dermis, muscle, subcutaneous tissues and internal organs. These acid-fast bacilli, resembling human and rat leprosy bacilli, together with other actinomycotic bodies, appeared to explain the characteristic macrophage granuloma observed in such lesions, similar to those of humans. These isolates possessed fundamental similarities to the human isolates of chemoautotrophic nocardioform bacteria reported earlier.
