Neisseria

(nis-e’re-ah) [Albert L. S. Nei er, phys i- Pertaining to or affected nelavan (nel’ah-van). NEO-ARTHROSIS cian in Breslau, born 1855, the discoverer of the gonococcus]. A genus of diplococci made up of biscuit-shaped hemispheres with the flattened sides adjacent. N. al’bicans, a non-motile species from the vaginal secretion, often in groups: it is much larger than the gonococcus, which it resembles. N. babe’sii, a pathogenic species composed of flattened cocci girdled with a yellowish zone: from the blood, red blood-corpuscles, and flesh of cattle with epidemic hemoglobinuria. N. cit’rea, a non-motile species from the pus of gonorrhea and from the dust of air; forming coherent ma es of tetrads: it produces a lemon-hued pigment. N. edinto’nii, a non-pathogenic and non-motile species found in the blood and desquamated epidermis of scarlatina. The cocci are hyaline. N. fla’va liquefa’ciens tar’da, a non-motile and non-pathogenic form from the skin in seborrhea: it produces a sulphur-yellow or yellow-green pigment. N. fr. dio’rum, a non-motile species from soil. N. gonorrho’s. Same as Micrococcus gonorrhee. N. lac’tea, a non-pathogenic species from sputum and from vaginal secretions. N. lys’ses, a hyaline species from the brain and spinal cord in rabies. N. miche’li, a species somewhat like the gonococcus, derived from the follicles of trachoma, of which disease it is the cause. N. petechia’lis, a species from the blood and petechise of typhus fever. N. rebel’lis, a species from the follicles of trachoma. N. rosa’- cea, a non-pathogenic species from the air. N. ro’sea, a non-pathogenic and non-motile species from the air, producing a rose-red pigment. N. subfla’va, a non-motile species from the healthy urethra and from vaginal secretions and _ lochia. Subcutaneously injected, it causes large absce es. N. tardis’sima, a nearly non-motile species from urethral pus. N. weic elbaum’ii, an intracellular species from the fresh exudate of cerebrospinal meningitis: pathogenic to various animals. N. winck'leri, a species in hyaline diplococci from riberi.
