Donovan who first described the type species. Pleomorphic non-motile rods, exhibiting single or bipolar condensations of chromatin. Occur singly and in clusters. May be capsulated or non-capsulated. Gram-negative. Growth outside human body occurs only in the yolk, yolk sac or amniotic fluid of developing chick embryo or in a medium containing embryonic yolk. Pathogenic for man causing granulomatous lesions, particularly in the inguinal region. The type species is Donovania granulomatis Anderson, De Monbreun and Good- pasture . 1. Donovania granulomatis Anderson et al. (Epithelial cell parasites, Dono- van, Indian Med. Gaz., Jfi, 1905, 414; Donovan bodies, Dienst, Greenblatt and Sanderson, Jour. Inf. Dis., 62, 1938, 112; Donovan organism, Anderson, Science, 97, 1943, 560; Anderson, De Monbreun and Goodpasture, Jour. Exp. Med., 81, 1945, 25.) From M. L. granuloma, of granuloma. Pleomorphic rods 1 to 2 microns in length, with i-ounded ends, occurring singly and in clusters. Intracellular forms usually capsulated. Non-motile. Gram-negative. No growth on ordinary culture media. Chick embryo: Grows readilj^ in yolk, yolk sac and feebly in amniotic fluid of developing chick embryo. Embryonic yolk medium: Growth occurs. Distinctive characters: Capsulated forms readily demonstrated by means of Wright's stain as blue bacillary bodies surrounded by well-defined dense pink- ish capsules. Non-capsulated fo
