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.

Evaluation of immune response to HBV vaccine in the staff and students of Sabzevar University of Medical Sciences (2014-15) Background:Hepatitis B is a bloodborne infections and it is predicted that about two billion people in the world have been exposed to the hepatitis B virus. Because of occupational reasons, medical students and staffs are more susceptible to expose to this disease than other members of society. Materials and Methods:This study is a descriptive-analytic study and 238 staffs and students of Sabzevar University of Medical Sciences were randomly selected and sampled. Then, the antibody titer of surface anti-protein of hepatitis B virus (HBs- Ab) was measured using ELISA method and the results were analyzed using the software Stata 12 after recording the demographic results and information. Results:Out of 238, 156 persons were female ( 65.5%) and 82 persons ( 34.5%) were male. 66% of individuals had antibody higher than 10 mu/ml and 37.4 % of individuals showed the appropriate answers higher than 100 u/ml. The relationship between job, sex and marital status with the immune response was significant. 100% of people who received full dose along with the booster vaccine were immune. Over time, the percentage of immune people has been decreased. Conclusion:Considering the reduction of response to vaccines over time and healthcare personnel being at risk, it is recommended that antibody titer was periodically examined in these individuals in 5 to 10 years to administer a booster dose in the case of a decrease in antibody titers.

Background and Purpose: Type a influenza virus causes infection in man, avian and primates. It has recently been reported that avian H5N1 and H9N2 subtypes were transferred to man. The purpose of the study is, therefore, to investigate the probability of H9N2 transmission from poultry to people engaged in poultry farming industries.
Methods and material: In this study, serological tests were carried out on 100 blood samples of contacted cases and special antibody of H9N2 subtype was measured by hemagglutination inhibition. Also, the sensitivity and specificity of the prepared ELISA test kit were measured in comparison with the standard method of hemagglutination inhibition. Out of 100 HI tests, 45 cases were normally selected and measured by ELISA.
Results: 66 percent of contacted cases had the specific H9N2 antibody. ELISA specificity and sensitivity, in comparison with HI, were 20% and 87.5% respectively.
Conclusion: The Presence of H9N2 antibody in the subject's serum suggest the prevalence of H9N2 virus among poultry, its transfer to people exposed and the possibility of their infection. Also, diagnosis influenza H9N2 antibody.
