Electron microscopic characteristics of actinomycetic agents having aetiological association with human leprosy and epizootic ulcerative syndrome of fish.

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.

Los actinomicetos termofilos de JuJuy: I. Monosporados / The Actinomycetes thermophiles of Jujuy, Argentina: I. Monosporium

Se aislaron cepas de Thermoactinomyces thalpophilus, T. dichotomica y Saccharomonospora viridis, a partir de restos vegetales y residuos de la industria azucarera obtenidos en la zona subtropical jujeña. Estas especies están consideradas como agentes causales de neumonitis alérgica
