[Identification of bacteria from use-surface disinfectant solutions and their sensibility against disinfectants (author's transl)]. 1981

W Dott, and M Exner, and L Krizek

The investigations are concerned with bacteria which had been isolated from use-surface disinfectant solutions originated from 19 disinfection dosage apparatus of different hospitals and from 8 taps of a centralised disinfection dosage apparatus in an other hospital. The greatest part of the isolated bacteria belonged to the genus Pseudomonas. Beyond it there were yellow-pigmented bacteria like Xanthomonas, Flavobacterium and Micrococcus. After subculture on solid peptone-containing media most of the isolated bacteria turned out to be sensitive to the disinfection solutions in a concentration range, that had been applied in the dosage apparatus. The examination of 6 disinfectants showed, that there were considerable differences in the efficiency to kill the bacteria. Even one preparation pointed out to be absolutely ineffective at applied concentrations.

UI	MeSH Term	Description	Entries
D008835	Micrococcaceae	A family of bacteria ranging from free living and saprophytic to parasitic and pathogenic forms.
D011548	Pseudomonadaceae	A family of gram-negative bacteria usually found in soil or water and including many plant pathogens and a few animal pathogens.	Azomonas,Azomonas agilis,Azotobacteraceae
D004202	Disinfectants	Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)	Biocide,Disinfectant,Biocides
D004340	Drug Contamination	The presence of organisms, or any foreign material that makes a drug preparation impure.

D005417	Flavobacterium	A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in SOIL and WATER. Its organisms are also found in raw meats, MILK and other FOOD, hospital environments, and human clinical specimens. Some species are pathogenic in humans.
D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
