Synthesis and Characterization of Novel Antibacterial PDDA/Honey Nanofiber Against Gram-Positive and Gram-Negative Bacteria
Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial na...
متن کاملInteraction of azthreonam and related monobactams with beta-lactamases from gram-negative bacteria.
Monobactams containing 3 beta-aminothiazolyl oxime side chains (SQ 81,377, SQ 81,402, azthreonam, and SQ 26,917) have poor affinities for the broad-spectrum beta-lactamases TEM-2 and K1. Addition of a 4-methyl substituent significantly increased stability to hydrolysis by these enzymes. P99 cephalosporinase from Enterobacter cloacae was strongly inhibited by the monobactams. Interaction of azth...
متن کاملCharacterization of the Extended-Spectrum beta-Lactamase Producers among Non-Fermenting Gram-Negative Bacteria Isolated from Burnt Patients
Background & Aims of the Study: Extended-spectrum beta-Lactamases (ESBLs) represent a major group of beta-lactamases which are responsible for resistance to oxyimino-cephalosporins and aztreonam and currently being identified in large numbers throughout the world. The objective of this study was to characterize ESBL producers among non-fermenter gram-negative bacteria isolated from burnt patien...
متن کاملInactivation of cephamycins by various beta-lactamases from gram-negative bacteria.
The enzymic inactivation of cephamycins, i.e. cefoxitin, cefmetazole, cefotetan and cefbuperazone, was investigated by means of bioassay, high pressure liquid chromatography (HPLC) and spectrophotometric analysis using three types of cephalosporinase (CSase, RICHMOND type Ia, Ib and Ic) and one penicillinase (PCase, TEM type). These four cephamycins were not inactivated by Ic CSase and TEM type...
متن کاملMethods for distinguishing gram-positive from gram-negative bacteria.
Lysis by KOH and hydrolysis of L-alanine-4-nitroanilide were compared with the Gram reaction of aerobic, microaerophilic, and anaerobic bacteria. Both tests correlated well with the Gram reaction with nonfermentative bacilli and Bacillus species, whereas they did not correlate with nonsporulating anaerobes. Only campylobacteria were KOH positive and L-alanine-4-nitroanilide and gram negative.
