Background: β-lactamase mediated resistance is the most common mechanism which renders the β-lactam antibiotics ineffective against bacteria including Escherichia coli. The development of resistance has led to the widespread empirical use of higher generation cephalosporins and it is likely that the third generation cephalosporins are also losing their efficacy by the same mechanism. The presen...
Background: Staphylococcus saprophyticus is the second most frequent community-acquired causative agent of urinary tract infection (UTI). The objective of this study was to evaluate the susceptibility profile and resistance detection in Staphylococcus species. isolated from patients with UTI. Materials and Methods: The isolates were investigated using the disk diffusion method, Vitek I system, ...
ABSTRACT Background and Objective: One of the main tasks of clinical microbiology laboratories is to determine antibiotic resistance profiles in common pathogens and ensure the selection of effective antibiotics for certain infections. The aim of this study was to compare the methods of disk diffusion, broth microdilution and modified Hodge test i...
Background & Objectives: Resistance to antibiotic and also the side effects of drug consumption are the main problem in antibiotic treatment. Therefore, after doing researches on the plants properties, humankind has attempted to use them in different industries. In this investigation the anti-microbial effects of ethanolic extracts of four medicinal plants from Ardebil province include Nepeta n...
abstract background and aim: oral infections and dental caries are considered as two serious public health problems, which inflict a costly burden on health care services worldwide, especially in the developing countries. the aim of this study was to evaluate the antibacterial activity of iranian licorice aqueous root extract on lactobacillus acidophilus in comparison with chlorhexidine. materi...
مقدمه: آنزیم های بتالاکتاماز tem، ctx-m، shv و amp-c از آنزیم هایی هستند که بر روی عناصر قابل انتقال واقع شده اند،esbl ها بتالاکتامازهای هیدرولیز کننده پنی سیلین ها، سفالوسپورینهای وسیع الطیف و آزترئونام می باشند. آنزیم amp-c بر روی کروموزوم نیز واقع شده است. هدف از این بررسی تعیین فراوانی اشریشیاکلی های تولیدکننده esbl وارزیابی مولکولی بتالاکتامازهای tem، ctx-m، shv و amp-c توسط pcr و بررسی ژن...
background and objectives: urinary tract infections (utis) are of the most common bacterial diseases worldwide. we investigate the antibiotic susceptibility patterns of escherichia coli (e. coli) strains isolated from pediatric patients with community acquired urinary tract infection (uti) to find a clinical guidance for choosing a right empirical antibiotic in these patients. materials and met...
background: the science of identification and employment of medicinal plants dates back to the early days of man on earth. cannabis (hashish) is the most common illegal substance used in the united states and was subjected to extensive research as a powerful local disinfecting agent for mouth cavity and skin and an anti-tubercular agent in 1950. methods: clinical strains were isolated from...
background and objectives: antibacterial susceptibility testing of clinical bacterial isolates through disk diffusion method plays a major role in antibacterial treatment. one of the main factors affecting the result of these tests is the type, structure and quality of the disks. the main objective of this study was to compare the agreement of antibiotic disks originated from three companies on...
background and objective: reports on mrsa strains are increasing worldwide. the aim of this study was to find the prevalence of mrsa strains isolated from clinical specimens and to evaluate their resistance profile. additionally we compared the phenotypic and genotypic methods for detection of methicillin resistance. materials and methods: in this cross-sectional study, a total of 41 isolates o...
