background: identifying regional types and evaluating the frequency of pneumococcal strains has become increasingly important especially in vaccination. the purpose of this study was the identification and frequency determination of our regional serotype and evaluation of the performance of recent type specific multiplex pcr for the diagnosis of streptococcus pneumonia serotypes. methods: all i...

conclusions the results indicate that the rates of esbls are high in urine e. coli and k. pneumoniae isolates from tehran hospitals. also this study indicates that the urine isolates from male patients are significantly more resistant than the female isolates. materials and methods a total of 190 e. coli and k. pneumoniae isolates were collected from patients’ urine samples in hospitals from te...

Objective: There are few therapeutic options for treatment of multidrug resistant Klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection). The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss extracts against ESBL-producing Klebsiella pneumoniae strains. Materials and Methods: This study was conducted on 100 K. pneumoniae isola...

background and objectives: klebsiella pneumoniae ( k. pneumoniae ) is an opportunistic microorganism. this study aimed to investigate the presence of mag a gene and antimicrobial susceptibility in k. pneumoniae . materials and methods: 195 clinical specimens were collected from hospitals of shahrekord, iran. bacterial culture, biochemical diagnostic standard test, determination of antibiotic se...

the role of chlamydia pneumoniae in asthma has drawn much attention in recent years. in this study we assessed the prevalence of c. pneumoniae infections in patients with chronic stable and acute exacerbation of asthma and compared it with normal population. twenty adult patients with chronic stable asthma and 21 patients with acute exacerbations of asthma and 41 matched control subjects were s...

background klebsiella pneumoniae is a family member of enterobacteriaceae. isolates of k. pneumoniae produce enzymes that cause decomposition of third generation cephalosporins. these enzymes are known as extended-spectrum beta-lactamase (esbl). resistance of k. pneumoniae to beta-lactamase antibiotics is commonly mediated by beta-lactamase genes. objectives the aim of this study was to identif...

Listeria monocytogenes can cause serious infection and recently, relapse of listeriosis has been reported in leukemia and colorectal cancer, and the patients with Klebsiella pneumoniae are at increased risk of colorectal cancer. Translation initiation codon recognition is basically mediated by Shine-Dalgarno (SD) and the anti-SD sequences at the small ribosomal RNA (ssu rRNA). In this research,...

conclusions this study confirmed the antimicrobial potential of investigated plants and their usefulness in treatment of resistant isolates of k. pneumoniae. results the isolates of k. pneumoniae were resistance to four of the agents including ceftazidime (60% of isolates) cefixime (60% of isolates), erythromycin (66.6% of isolates). the highest mic values of extract were found to be 250 ppm ag...
