 antibodies which fix complement with anti- gen from Miyagawanella lymphogranuloma- tosis. Pathogenic for man, apes and monkeys, affecting only the cornea and the conjunc- tiva, causing highly destructive lesions. Antibiotic- and chemo-therapy: Suscep- tible to sulfonamides and to antibiotics. Source: Found in the scrapings of either the cornea or the conjunctiva in cases of trachoma. Habitat: The etiological agent of tra- choma in man. 2. Chlamydia oculogenitalis (Mosh- kovskiy, 1945) Rake, comb. nov. (Chlamy- dozoon oculogenitale Aloshkovskiy, Uspekhi Souremennoi Biologii, 19, 1945, 12.) o.cu.lo.ge.ni.ta'lis. L. noun oculus eye; L. adj. genitalis genital; M.L. adj. oculo- genitalis (apparently intended to mean) the ocular and genital (organism). Resembles Chlamydia trachomatis morpho- logically and in staining reactions. Cultivation: Has not been cultivated. Immunology: Same as for C. trachomatis. Pathogenic for man, baboons and mon- keys. Causes an acute conjunctivitis and, in man, an inflammation of the lower uro- genital tract. Antibiotic- and chemo-therapy: Suscep- tible to sulfonamides and to antibiotics. Source: Found in conjunctival exudates and in exudates from infected urethra or cervix. Also present in contaminated pools of water. Habitat: The etiological agent of swim- ming-pool conjunctivitis (neonatal, or in- clusion, conjunctivitis). Genus II. Colesiota Rake, 1948. (Rake, in Manual, 6th ed., 1948, 1119.) Co.le.si.o'ta. M.L. dim. ending -iota; M.L. noun Colesiota named for Prof. J. D. W. A. Coles, the first to study these organisms. Usually coccoid cells, but pleomorphism is marked. Gram-negative. Occur intracytoplas- mically as colonies. Cause ophthalmic diseases in sheep. The type species is Colesiota conjunctivae (Coles) Rake. 1. Colesiota conjunctivae (Coles, 1931) Rake, 1948.

L. adj. conjunctivus con- nective; M.L. fem.n. conjunctiva the con- junctiva; M.L. gen. noun conjunctivae of the conjunctiva. Pleomorphic cells with diameters ranging from 200 millimicrons to 2 microns. May be uniformly staining coccoid forms or bacil- lary, triangular, annular or horse-shoe in form. Do not occur in chains. Colony-like masses are frequent. Not encapsulated. Non-motile. Stain with ordinary aniline dyes but less intensely than do bacteria. Gram-negative. Cultivation: Has not been cultivated. Immunology: Unknown. Tissue tropism: Affects only the conjunc- tiva and the cornea. Pathogenic for sheep. Causes acute con- junctivitis and keratitis. Habitat: Found in the scrapings of the cornea, the conjunctiva and in the dis- charges from affected eyes of sheep. The etiological agent of infectious, or specific, ophthalmia in sheep. Genus III. Ricolesia Rake, gen. nov. Ri.co.le'si.a. Ri- an arbitrarily formed prefix taken from Rickettsia; M.L. noun Colesia named for Prof. J. D. W. A. Coles, the first to study these organisms; M.L. fem.n. Ricolesia an arbitrarily formed generic name.
