Bacterium :: Bacterium (n.) A microscopic vegetable organism, belonging to the class Algae, usually in the form of a jointed rodlike filament, and found in putrefying organic infusions. Bacteria are destitute of chlorophyll, and are the smallest of microscopic organisms. They are very widely diffused in nature, and multiply with marvelous rapidity, both by fission and by spores. Certain species are active agents in fermentation, while others appear to be the cause of certain infectious diseases. See Bacillus

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.

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..

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

Anthrax :: Anthrax (n.) A microscopic, bacterial organism (Bacillus anthracis), resembling transparent rods. [See Illust. under Bacillus.].

Sterlet :: Sterilize (v. t.) To destroy all spores or germs in (an organic fluid or mixture), as by heat, so as to prevent the development of bacterial or other organisms..

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

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..

Micrococcus :: Micrococcus (n.) A genus of Spherobacteria, in the form of very small globular or oval cells, forming, by transverse division, filaments, or chains of cells, or in some cases single organisms shaped like dumb-bells (Diplococcus), all without the power of motion. See Illust. of Ascoccus..

Spore :: Spore (n.) A minute grain or germ; a small, round or ovoid body, formed in certain organisms, and by germination giving rise to a new organism; as, the reproductive spores of bacteria, etc..

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..

Microbion :: Microbion (n.) A microscopic organism; -- particularly applied to bacteria and especially to pathogenic forms; as, the microbe of fowl cholera..

Leptothrix :: Leptothrix (n.) A genus of bacteria, characterized by having their filaments very long, slender, and indistinctly articulated..
