Prevalence of Genes Encoding Aminoglycoside Modifying Enzymes in Clinical Isolates of Klebsiella Pneumoniae in the Hospitals of Borujerd
Background and Aims: Given the importance of aminoglycoside resistance in nosocomial and community infections caused by bacterial pathogenes such as Klebsiella pneumoniae (K. pneumoniae), the aim of this study was to determine the frequency of aac (6')- Ib and aac (3)- IIa, the genes encoding aminoglycoside modifying enzymes involved in aminoglycoside resistance. Material and Methods: A t...
متن کاملBacteriocin typing of streptococcal isolates from endocarditis.
A typing system based on bacteriocin production and sensitivity for Streptococcus sanguis strains was devised. Bacteriocin producer strains were grown (37degrees C) anaerobically on brain heart infusion-yeast extract agar for 18 h. Bacteriocin indicator strains were suspended to molten brain heart infusion-yeast extract agar and then overlayed onto the producer strain. After an additional 18 to...
متن کاملrole of cultural iran in promotion of multilaieralism in central asia and caucasus
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
15 صفحه اولDetermination of Bacteriocin Genes and Antibacterial Activity of Lactobacillus Strains Isolated From Fecal Healthy Individuals
Lactobacillus species play an important role in gastrointestinal (GI) tract function, intestinal microbiota balance, and the immune system activity by exerting a strong activity against many intestinal pathogens. The aim of this study was to isolate Lactobacillus species from fecal samples, investigate their antimicrobial properties, and characterixe their bacteriocins encoding genes. 48 fecal ...
متن کاملPrevalence of TEM and SHV Genes in Clinical Isolates of Klebsiella Pneumonia From Mashhad, North- East Iran
Background & Objectives:Extended-spectrum-B-lactamase (ESBL)-producing strains of Klebsiella Pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. This study was performed to determine the prevalence of ESBL-producing K. Pneumonia and to evaluate the frequency of TE...
متن کاملConcomitant synthesis of bacteriocin and bacteriocin inactivator from Serratia marcescens.
We have found that Serratia marcescens strain P & S is bacteriocinogenic. However, the phenotypic expression of bacteriocin activity depends upon the temperature at which the cells are grown. When the organism is grown at 30 to 37 C, no bacteriocin activity can be demonstrated, whereas when it is grown at 39 C bacteriocin activity is readily observed. It appears that the P & S strain concomitan...
