AbstractIntroduction: Portulaca oleracea is one of the most utilized herbs in the world. According to some antibacterial effect of plants extracts, it seems that this extracts can be used in the bacterial infection treatments. In order to assessment of antibacterial effect of the Portulaca oleracea extract, we determined minimum inhibitory and minimum bactericidal concentration of the Portulaca oleracea extract on the pathogenic bacterial species that antibiotic resistant pattern was determined in this species.Methods: Hydro-Alcoholic extract of the Portulaca oleracea was harvested. Bacterial species including S. aureus, P. aeruginosa, L. monocytogenes, A. baumannii, E. coli and K. pneumonia was collected from the Iran pasteur institute. Antibiogram was determined by disk diffusion method and then MIC and MBC of Hydro-Alcoholic extract of the Portulaca oleracea was determined.Results: Highest MIC concentration was observed in P. aeruginosa, L. monocytogenes, E. coli and K. pneumonia. While highest MBC concentration related to L. monocytogenes.Conclusion: Herbal antibacterial extracts can be useful in human infection control. In order to this goal, in this study antibacterial effect of Portulaca oleracea extract determined against six important pathogens. According to Our results hydro-alcoholic extract of Portulaca oleracea show antibacterial effect on human pathogens including E. coli, K. pneumonia, S. aureus, A. baumannii, P. aeruginosa and L. monocytogenes.

Background: Considering the necessity of hospital infection control because of the long recovery time and increasing the mortality of patients as well as the lack of accurate reports and statistics of some hospitals, the prevalence of nosocomial infections and associated factors were examined in Vasei Hospital of Sabzevar during the years of 2009-2013. Materials and Methods: This study is a descriptive-analytical research. Of 89429 patients admitted during the years of 2009-2013, 1046 cases of patients with nosocomial infections in Vasei Hospital of Sabzevar were studied using SPSS version 22 and chi-square test.Results: According to the result of this study, the prevalence of nosocomial infections in all wards of the hospital was 1.2 percent (1046 patients), and the prevalence of nosocomial infections based on the type of infection in hospitalized patients was infections of urinary tract, 0.4% (367 patients), respiratory, 0.5 % (468 patients), anemia, 0.1 % (52 patients), and surgical wounds, 0.3% (277 persons). The most common nosocomial infection was related to the respiratory infections, which is 44 percent of all infections cases. A significant relationship between age, sex and type of infection was not observed. The most common isolated microorganism was coagulase-negative Staphylococci.Conclusion: With accepted prevalence and compare to other studies, the prevalence of nosocomial infections has been reported less than the standard. The results of our research encourage us to standardize the hospital infection reports reported by hospitals as well as solve available problems.
