typing

 [tīp´ing]
in transplantation immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (such as those on leukocytes or erythrocytes) are detected by means of suitable isoimmune antisera.
blood typing (typing of blood) determining the character of the blood on the basis of agglutinogens in the erythrocytes; see also blood group.
phage typing characterization of bacteria, extending to strain differences, by demonstration of susceptibility to one or more races (a spectrum) of bacteriophage; widely applied to staphylococci, typhoid bacilli, and other organisms for epidemiological purposes.
tissue typing identification of the human leukocyte antigens of the donor and recipient of a transplant or transfusion; see also tissue typing.

phage typing

[fāj]
Etymology: Gk, phagein, to eat, typos, mark
the identification of bacteria by testing their vulnerability to bacterial viruses.

phage typing

a technique that uses BACTERIOPHAGES to identify BACTERIA on the basis of their susceptibility to specific phages.

phage


phage type
an intraspecies type of bacterium demonstrated by phage typing; called also lysotype and phagotype.
phage typing
characterization of bacteria, extending to strain differences, by demonstration of susceptibility to one or more (a spectrum) races of bacteriophage; widely applied to staphylococci, typhoid bacilli, etc., for epidemiological purposes.

typing

in transplantation and transfusion immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (e.g. those present on leukocytes) or other cell surface antigens, e.g. red blood cell antigens, are detected by means of suitable immune serum.

blood typing
determining the antigenic determinants present on the surface of red blood cells by using specific antibodies (typing serums). See also blood group.
