two strains, hg104 and asso, were isolated crom the soil of tehran's suburbs. taxonomic studies showed thathg104 and as50 belong to mycobacterium spp. and brevibacterium spp. respectively, which produce antibacterial substances with relatively high activity against some important clinical gram-positive and gramnegative bacteria
Background: The increasing use of β-lactam antibiotics in clinics for the treatment of different bacterial infections since early 1980s has led to increased rates of resistant bacteria isolated from patients. One of the problems in the treatment of nosocomial infections is related to resistant bacteria such as Enterobacter cloacae due to cross resistance through extended-spectrum beta-lactamase...
conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...
Several heavy metal resistant bacterial strains were isolated from sediment and water samples collected from the Persian Gulf and enclosed industrial areas. All the isolated bacteria were identified by 16S rRNA gene sequencing. Isolated bacteria were tested for the presence of plasmids using the modified alkaline lysate method. The method was effective for identification and characterization of...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
background: in this study, we determine the vector competence of musca domestica with reference to the transmission of susceptible and resistance bacterial strains in hospitals and slaughter house in sanandaj city, west iran. methods: totally 908 houseflies were collected to isolate bacteria from their external body based on standard procedures.antibiotic susceptibility testing was performed ...
Abstract Background: By increasing resistance of pathogenic bacteria to antibiotics, many attempts have been made by the researchers to find new compounds as a substitute for non-effective antibiotics. The aim of this research is a comparative study of antibacterial properties of four species on standard strains of Escherichiacoli, Shigellaflexneri, Klebsiella pneumonia, Candida and Candida alb...
xenorhabdus and photorhabdus are members of the family enterobacteriaceae, and are engaged in a mutualistic association with the entomopathogenic nematodes, steinernema and heterorhabditis, respectively. in the present study, the organic fraction of ethyl acetate bacterial crude extracts of the symbiotic bacteria, xenorhabdus stockiae and photorhabdus luminescens isolated from entomopathogenic ...
198 lactic acid bacteria (lab) were isolated from iranian milk samples. almost all isolatedlab showed inhibitory activity towards e. coli and s. aureus as gram negative and grampositive indicators, respectively. no role was observed for hydrogen peroxide in the activity ofall isolated strains while organic acids proved a prominent role in all detected inhibitoryactivities. within isolated lab, ...
Background and Objective: One of the most common bacterial infections in the children is urinary tract infection (UTI) that its early diagnosis and proper treatment has high importance and analysis of typing and antibiotic resistance of isolated bacteria from urine of children with different sex and ages can help empirical therapy of UTI before preparing lab data. Materials and Methods: The da...
