Antitoxine :: Antitoxine (n.) A substance (sometimes the product of a specific micro-organism and sometimes naturally present in the blood or tissues of an animal), capable of producing immunity from certain diseases, or of counteracting the poisonous effects of pathogenic bacteria..

Sarcina :: Sarcina (n.) A genus of bacteria found in various organic fluids, especially in those those of the stomach, associated with certain diseases. The individual organisms undergo division along two perpendicular partitions, so that multiplication takes place in two directions, giving groups of four cubical cells. Also used adjectively; as, a sarcina micrococcus; a sarcina group..

Plasmid :: Plasmid (n.) A piece of DNA, usually circular, functioning as part of the genetic material of a cell, not integrated with the chromosome and replicating independently of the chromosome, but transferred, like the chromosome, to subsequent generations. In bacteria, plasmids often carry the genes for antibiotic resistance; they are exploited in genetic engineering as the vehicles for introduction of extraneous DNA into cells, to alter the genetic makeup of the cell. The cells thus altered may produ

Torula :: Torula (n.) A chain of special bacteria. (b) A genus of budding fungi. Same as Saccharomyces. Also used adjectively.

Pathogene :: Pathogene (n.) One of a class of virulent microorganisms or bacteria found in the tissues and fluids in infectious diseases, and supposed to be the cause of the disease; a pathogenic organism; a pathogenic bacterium; -- opposed to zymogene..

Bacterioscopy :: Bacterioscopy (n.) The application of a knowledge of bacteria for their detection and identification, as in the examination of polluted water..

Bacteroidal :: Bacteroidal (a.) Resembling bacteria; as, bacteroid particles..

Pleomorphism :: Pleomorphism (n.) The theory that the various genera of bacteria are phases or variations of growth of a number of Protean species, each of which may exhibit, according to undetermined conditions, all or some of the forms characteristic of the different genera and species..

Panspermy :: Panspermy (n.) The doctrine of the widespread distribution of germs, from which under favorable circumstances bacteria, vibrios, etc., may develop..

Bactericidal :: Bactericidal (a.) Destructive of bacteria.

Aerobies :: Aerobies (n. pl.) Microorganisms which live in contact with the air and need oxygen for their growth; as the microbacteria which form on the surface of putrefactive fluids.

Pseudobacteria :: Pseudobacteria (n. pl.) Microscopic organic particles, molecular granules, powdered inorganic substances, etc., which in form, size, and grouping resemble bacteria..

Mycoprotein :: Mycoprotein (n.) The protoplasmic matter of which bacteria are composed.

Leptothrix :: Leptothrix (n.) Having the form of a little chain; -- applied to bacteria when, as in multiplication by fission, they form a chain of filiform individuals..

Germicide :: Germicide (a.) Destructive to germs; -- applied to any agent which has a destructive action upon living germs, particularly bacteria, or bacterial germs, which are considered the cause of many infectious diseases..

Zoogloea :: Zoogloea (n.) A colony or mass of bacteria imbedded in a viscous gelatinous substance. The zoogloea is characteristic of a transitory stage through which rapidly multiplying bacteria pass in the course of their evolution. Also used adjectively.

Zymogene :: Zymogene (n.) One of a physiological group of globular bacteria which produces fermentations of diverse nature; -- distinguished from pathogene.

Bacteria :: Bacteria (n.p.) See Bacterium.

Streptococci :: Streptobacteria (n. pl.) A so-called variety of bacterium, consisting in reality of several bacteria linked together in the form of a chain..

Toxine :: Toxine (n.) A poisonous product formed by pathogenic bacteria, as a toxic proteid or poisonous ptomaine..
