Characterization and identification of gram-negative, nonfermentative bacteria.
The morphological and physiological characteristics of 593 strains of nonfermentative, gram-negative bacteria are described. A battery of 46 tests was used to identify and differentiate strains representing 8 genera and 31 species of named and group-designated bacteria. Seven selected amides and organic salts were closely examined to determine their usefulness, individually or as a battery, in ...
متن کاملAntagonistic activity of Streptomyces gresiofuscus PTCC1628 against isolated Gram negative bacteria from Urinary Tract Infections
Antibiotics are the best known products of actinomycete. Over 5,000 antibiotics have been identified from the cultures of Gram positive and Gram-negative organisms, and filamentous fungi, but only about 100 antibiotics have commercially been used to treat human, animal and plant diseases. The genus, Streptomycete, is responsible for the formation of more than 60% of known antibiotics. Bacteri...
متن کاملEfficacy of Amikacin and Imipenem Against Multi-Drug Resistant Gram-Negative Bacteria Isolated From Wound Infections
Background and Objective: Gram-negative pathogens are considered the common cause of wound infections associated with increased mortality and morbidity rates. Antibiotics combination has been used to overcome this problem. Aims: In this study, we identify Gram-negative pathogens found in wound infections and assess the in-vitro efficacy of a combination of amikacin and imipenem against the resi...
متن کاملDetection of arginine dihydrolase in nonfermentative gram-negative bacteria by use of thin-layer chromatography.
Thin-layer chromatography was used to detect the presence of the arginine dihydrolase system in nonfermentative gram-negative bacteria. The test was positive for the fluorescent pseudomonads as well as Pseudomonas maltophilia, whereas other Pseudomonas sp., Mima, and Herellea were negative. This procedure can be completed in a few hours and may be useful in the clinical laboratory.
متن کاملSimple screening tests for detection of carbapenemases in clinical isolates of nonfermentative Gram-negative bacteria.
BACKGROUND & OBJECTIVE The production of carbapenemases is an important mechanism responsible for the carbapenem resistance. A simple and inexpensive testing method for screening of carbapenemase producers is essential. A prospective study was undertaken to detect metallo-beta-lactamases (MBLs) and AmpC beta-lactamases in nonfermentative Gram negative bacteria and to evaluate the various method...
