RT Journal Article SR Electronic T1 Isolation of Neisseria lactamicus from the nasopharynx JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 399 OP 400 DO 10.1136/jcp.26.6.399 VO 26 IS 6 A1 Pykett, Angela H. YR 1973 UL http://jcp.bmj.com/content/26/6/399.abstract AB During 1971 and 1972, 71 cultures of neisseriae that attacked lactose were received by this laboratory. All strains except one from an eye swab were from the nasopharynx of healthy subjects. Nineteen similar strains from the nasopharynx were isolated in this laboratory. The characteristics of these strains were compared with those of Neisseria meningitidis, Neisseria pharyngis, Neisseria catarrhalis, and Neisseria lactamicus. The 90 strains under investigation closely resembled Neisseria meningitidis but could be differentiated by production of acid from lactose and beta-galactosidase activity and were therefore classified as Neisseria lactamicus.
