A comparative study was done on the transfer frequency of R factors from 90 strains of multiple drug-resistant Aerobacter and 81 strains of Klebsiella to Escherichia coli CSH-2 (F(-), met(-), pro(-), Nal-r). The most common resistance patterns for the Aerobacter isolants were ampicillin streptomycin chloramphenicol tetracycline and ampicillin streptomycin chloramphenicol tetracycline kanamycin ...

Genetic transformation studies were carried out to standardize a protocol for Agrobacterium -mediated genetic transformation of three economically important strawberry (Fragaria x ananassa Duch) cultivars Kurdistan’, Camarosa’, and ‘Paros’. Shoot regeneration frequency 72, 65 and 30% was obtained on MS (1) basal medium supplemented with 2% glucose and 4 mg/l TDZ for Camarosa, Kurdistan and Paro...

Two kanamycin-resistant variants of Nicotiana tabacum were derived by culturing seedling leaf sections on a shoot-inducing medium containing kanamycin. The variants displayed a higher resistance to the structurally related antibiotic streptomycin than to kanamycin. The resistance phenotype was expressed when the tissue was cultured either as callus or as a differentiating tissue and was stably ...

Cerebrospinal fluid (CSF) diffusion of kanamycin was studied in 35 newborn infants. Five infants had bacterial meningitis and two had viral meningitis. One-half of the infants received an intramuscular injection of 7.5 mg of kanamycin per kg, whereas the other half received 12.5 mg/kg. Serum and CSF specimens were obtained 3 to 6 hr and 11 to 12 hr after injection. No significant difference was...

Previous studies have shown that pretreatment with sub-lethal kanamycin to E. coli B23 cells provided protection against subsequent exposure to lethal amounts of the same antibiotic. It has also been shown that exposure to sub-inhibitory levels of certain antibiotic can induce cross resistance by promoting the development of low-level resistance to other functional and structural unrelated anti...

A small group of institutionalized Down’s syndrome patients were treated with topical kanamycin sulphate paste, once or twice a day for 3-5 days, every fifth week over a 52-week-period. The teeth were not brushed during this 52-week-period. The wet weight of the supragingival plaque in the kanamycin group was significantly reduced when compared to the supragingival plaque formed in the group re...

Problem statement. In accordance with the code of rules (SP 101.13330.2012), use fish protection devices a filter screen and flushing system applies to water intake facilities in various placement conditions, this regard, it is relevant expand possibilities using cassettes at shallow depths source.
 Results. A methodology has been developed substantiate filler parameters horizontal cassett...

Kanamycin production by Streptomyces kanamyceticus ATCC 12853 requires magnesium sulfate and potassium phosphate at concentrations of 0.4 and 1.0 g per liter, respectively. The optimal concentrations of Fe and Zn for production of kanamycin are 0.25 and 0.575 mug/ml, respectively, whereas Mo at 0.04 mug/ml allows maximal cellular growth and antibiotic synthesis. Mn and Ca are without any effect...
