| wild type | <genetics> The naturally-occuring, normal, non-mutated version of a gene. The original parent strain of a virus, bacteria, fruit fly, mouse, or other laboratory test organism. Often refers to how organisms are found naturally, in the wild, before mutations were induced by researchers. (09 Oct 1997) |

| MPGN type i | A kidney disorder which results in kidney dysfunction. Inflammation of the glomeruli result from an abnormal immune response and the deposition of antibodies within the kidney (glomerulus) ultrastructure. Membranoproliferative glomerulonephritis (MPGN) has been divided into two different types in the basis of where the antibodies are deposited in the glomerulus. MPGN type I, the more common type, deposits antibodies in the subendothelial layer of the basement membrane, whereas type II deposits antibodies in the bottom layer of the basement membrane. Symptoms include cloudy urine (pyuria), decreased urine output, swelling and hypertension. This disorder often results in end-stage renal disease. (27 Sep 1997) |

| woodbury-type | 1. A process in photographic printing, in which a relief pattern in gelatin, which has been hardened after certain operations, is pressed upon a plate of lead or other soft metal. An intaglio impression in thus produced, from which pictures may be directly printed, but by a slower process than in common printing. 2. A print from such a plate. Origin: After the name of the inventor, W. Woodbury. Source: Websters Dictionary (01 Mar 1998) |

| C type lectin | <cell biology> One of two classes of lectin produced by animal cells, the other being the S type. The C type lectins require disulphide linked cysteines and Ca ions in order to bind to a specific carbohydrate (c.f. S type lectins). The carbohydrate recognition domain of C type lectins consists of about 130 amino acids which contains 18 invariant residues in a highly conserved pattern. These invariant residues include cysteines which probably form disulphide bonds. So far, all identified C type lectins are extracellular proteins and include both Integral membrane proteins, such as the asialoglycoprotein receptor and soluble proteins. (06 Aug 1998) |
| C type virus | <molecular biology, virology> Originally C type particles identified in mouse tumour tissue and later shown to be oncogenic RNA viruses Oncovirinae) that bud from the plasma membrane of the host cell starting as a characteristic electron dense crescent. Include feline leukaemia virus, murine leukaemia and sarcoma viruses. (18 Nov 1997) |
| haemophilus influenzae type b | The majority of type b isolates are from biotype I. The organism can cause life-threatening meningitis, primarily in children 6-12 months of age. Children with underlying disease or immunodeficiency are also at high risk for infection. A vaccine is available and recommended for children under 5 years of age. (12 Dec 1998) |
