[Bactericidal dosie-activity relationships with E. coli, K. pneumoniae and Staph. aureus (author's transl)]. 1976

P M Shah, and Junghanns, and W Stille

In investigations into the dosis-activity relationships of bactericidal antibiotics used against E. coli, K. pneumoniae and Staph. aureus four types of activity could be demonstrated. The penicillin type shows almost no improvement in bactericidal activity despite increasing the dosage above a certain level. An increase in concentration of aminoglycoside antibiotics led to a more rapid killing of the bacteria. In cefalotin there was a linear dosis-activity relationship: rising concentrations of antibiotics led to an ever increasing bactericidal effect. The paradoxical bactericidal effect ("Eagle effect'') described for penicillin G with enterococci could not be demonstrated.

D007711	Klebsiella pneumoniae	Gram-negative, non-motile, capsulated, gas-producing rods found widely in nature and associated with urinary and respiratory infections in humans.	Bacillus pneumoniae,Bacterium pneumoniae crouposae,Hyalococcus pneumoniae,Klebsiella pneumoniae aerogenes,Klebsiella rhinoscleromatis
D010068	Oxacillin	An antibiotic similar to FLUCLOXACILLIN used in resistant staphylococci infections.	Oxazocilline,Penicillin, Methylphenylisoxazolyl,Sodium Oxacillin,Oxacillin Sodium,Oxacillin, Monosodium Salt, Anhydrous,Oxacillin, Monosodium Salt, Monohydrate,Prostaphlin,Methylphenylisoxazolyl Penicillin,Oxacillin, Sodium,Sodium, Oxacillin
D010400	Penicillin G	A penicillin derivative commonly used in the form of its sodium or potassium salts in the treatment of a variety of infections. It is effective against most gram-positive bacteria and against gram-negative cocci. It has also been used as an experimental convulsant because of its actions on GAMMA-AMINOBUTYRIC ACID mediated synaptic transmission.

D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.

D011113	Polymyxins	Basic lipopeptide antibiotic group obtained from Bacillus polymyxa. They affect the cell membrane by detergent action and may cause neuromuscular and kidney damage. At least eleven different members of the polymyxin group have been identified, each designated by a letter.	Polymyxin,Polymyxin M
D002228	Carbenicillin	Broad-spectrum semisynthetic penicillin derivative used parenterally. It is susceptible to gastric juice and penicillinase and may damage platelet function.

D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
D005839	Gentamicins	A complex of closely related aminoglycosides obtained from MICROMONOSPORA purpurea and related species. They are broad-spectrum antibiotics, but may cause ear and kidney damage. They act to inhibit PROTEIN BIOSYNTHESIS.
