| 설명 | 세균에 감염되어 그 세포 내에서만 증식하는 바이러스 세균을 숙주로 하는 바이러스로 세균바이러스라고도 한다. 즉, 핵산과 소수의 효소를 단백질의 껍질로 싸고 있는 간단한 구조이며, 각각 특정의 세균종에만 감염한다. 세균에 기생하며 균체를 녹이는 바이러스이다. 유전 형질의 화학적 특성을 연구하는 데에 쓴다. 파지에는 DNA와 RNA 파지가 있으며, 기호와 숫자로 분류한다. 세균에 감염되어 세균을 용해시키는 것을 용균파지라 부르며, 숙주를 녹이지 않고 숙주 유전체에 들어가 공존하는 것을 템퍼레이트 파지라 부른다. 또, 동식물 세포에 감염하는 바이러스를 각각 동물 바이러스-식물 바이러스라 하는데 대하여 세균 바이러스라고도 한다. 세균여과기를 통과하며 광학현미경으로는 직접 볼 수 없는 미소한 입자이다. 살아있는 세포 내에서만 증식이 가능하고, 대사활성을 나타내는 일도 없다. |

| bacteriophage typing | A technique of bacterial typing which differentiates between bacteria or strains of bacteria by their susceptibility to one or more bacteriophages. (12 Dec 1998) |

| bacterial typing techniques | Procedures for identifying types and strains of bacteria. The most frequently employed typing systems are bacteriophage typing and serotyping as well as bacteriocin typing and biotyping. (12 Dec 1998) |
|---|---|
| phage typing | <microbiology> Bacteria may be typed by their susceptibility to a range of bacteriophages though confusion may arise if the bacteria carry plasmids encoding restriction endonucleases. (18 Nov 1997) |
| mycological typing techniques | Procedures for identifying types and strains of fungi. (12 Dec 1998) |
| HLA typing | <immunology> Tests done in order to determine if a patient has antibodies against a potential donor's HLA antigens. The presence of antibodies means that a particular graft will be rapidly rejected. (05 Mar 2000) |
| DNA typing | <molecular biology> See restriction fragment length polymorphism. (18 Nov 1997) |
| tissue typing | <procedure> The process of determining the allelic types of the antigens of the major histocompatibility complex (MHC) that determine whether a tissue graft will be accepted or rejected. at present carried out either by use of polyclonal or monoclonal antibodies against MHC antigens or less usually by tests of MHC restricted cell function or skin grafting (the latter not in humans). (18 Nov 1997) |
| typing | Classification according to type. Origin: see type Bacteriophage typing, a microbiological procedure, of epidemiological importance, for distinguishing types within a seemingly homogeneous bacterial species or strain by the use of type-specific bacteriophage. HLA typing, tests done in order to determine if a patient has antibodies against a potential donor's HLA antigens. The presence of antibodies means that a particular graft will be rapidly rejected. Also used to establish paternity and in forensic medicine. (05 Mar 2000) |
| bacteriophage | <microbiology, virology> Viruses that have a specific affinity for and infect bacteria. The bacteriophages that attack Escherichia coli are termed coliphages, examples of these are lambda phage and the T even phages, T2, T4 and T6. Basically, phages consist of a protein coat or capsid enclosing the genetic material, DNA or RNA, that is injected into the bacterium upon infection. In the case of virulent phages all synthesis of host DNA, RNA and proteins ceases and the phage genome is used to direct the synthesis of phage nucleic acids and proteins using the host's transcriptional and translational apparatus. These phage components then self assemble to form new phage particles. The synthesis of a phage lysozyme leads to rupture of the bacterial cell wall releasing, typically 100-200 phage progeny. The temperate phages, such as lambda, may also show this lytic cycle when they infect a cell, but more frequently they induce lysogeny. The study of bacteriophages has been important for our understanding of gene structure and regulation. Lambda has been extensively used as a vector in recombinant DNA studies. (15 Nov 1997) |
| bacteriophage 2 depolymerase | <enzyme> Hydrolyzes glycolipoproteins and lipopolysaccharides; releases aminosugars Registry number: EC 3.2.1.- Synonym: phage 2 depolymerase (26 Jun 1999) |
| bacteriophage immunity | The state induced in a bacterium by lysogenization, the lysogenic bacterium being insusceptible to further lysogenization or to a lytic cycle by a superinfecting bacteriophage, in contradistinction to bacteriophage resistance. (05 Mar 2000) |
| bacteriophage lambda | <microbiology, virology> A bacteriophage, or virus which infects bacteria, that infects E. Coli. It has a complex set of regulatory mechanisms to determine whether it will quietly insert its DNA into the bacterial genome to become dormant and to be reproduced whenever the bacterium reproduces (to lysogenize), or whether it will hijack the bacterium's cellular machinery to reproduce itself and prepare to infect more bacteria, causing the bacterium to self-destruct shortly after infection (to lyse). Lambda is particularly useful to geneticists because parts of it can be used to introduce foreign DNA into the bacterial genome, it is a cloning vector. (09 Oct 1997) |
| bacteriophage m13 | <microbiology> A bacteriophage (a virus which infects bacteria) that has single-stranded DNA. It is used as a method of obtaining single strands of foreign DNA so that the foreign DNA can be sequenced (that is, the order of its nucleotide bases can be determined). It is also used in procedures to create mutations in vitro (in a test tube rather than within an organism). (09 Oct 1997) |
| bacteriophage mu | An unassigned species of temperate coliphage, in the family myoviridae, composed of a linear, double-stranded molecule of DNA, which is able to insert itself at random at any point on the host chromosome. It frequently causes a mutation by interrupting the continuity of the bacterial operon at the site of insertion. (12 Dec 1998) |
| bacteriophage omicron x174 | <microbiology> A bacteriophage (a virus that infects bacteria) which has as its genetic material DNA in single strands instead of the usual double strands. The virus is useful to those who study how DNA replicates. (09 Oct 1997) |
| bacteriophage p1 | An unassigned species of temperate bacteriophage in the family myoviridae which infects e. Coli. It is the largest of the coliphages and consists of double-stranded DNA, terminally redundant, and circularly permuted. (12 Dec 1998) |
