Abstract
Abstract Background and objectives: Hydatid cyst is one of the most important zoonotic parasitic diseases produced by means of Larva stage of Echinococcus granulosus. Since this Hydatid cyst is a widespread disease in many regions of the world and Iran, we decided to study the epidemiological situation of patients infected with hydatid cyst who were operated in hospitals of Qom, Iran (2004-2007). Material and Methods: In this Cross-sectional retrospective study, we surveyed the Medical records of 19 patients infected with hydatid cyst, who were operated in hospitals of Qom (2004-2007). Patients’ demographic data including gender, age, career, dwelling place, number of cysts and the infected organ were collected and analyzed by SPSS software. Results: of the 19 patients, 12 cases (63.2%) are female and seven cases (36.8%) male. The highest rate of infection is related to 21-30 year group (31.65%) homemakers (52.7%) and urban (89.5%). The results show that the organs involved are liver (73.7%) and lung (26.3%). All patients infected with pulmonary hydatid cyst are male. Conclusion: Since 63.2 percent of infected people are female and homemaker, having contact with vegetables contaminated with parasite ova is the most important way of infection transmission.

Abstract
Abstract Background and objectives: Identification and monitoring of multidrug-resistant Mycobacterium tuberculosis strains (MDR) is highlighted by the high risk of their spreading in different areas. Prevalence of these strains was evaluated in Golestan province in northeast of Iran. Material and Methods: Drug susceptibility testing to Isoniazid and rifampin was carried out for 148 clinical samples that had grown in Mycobacteria growth indicator tube (MGIT) system, according to the manufacturer's instructions (Becton-Dickinson, USA). The association of drug resistance frequency with demographic characteristics and growth time were investigated. The appropriate statistical tests, X2 and student T- test were performed for comparison of these variants. A p value>0.05 was considered significant in all cases. Results: The turnaround time required for growth of Mycobacterium tuberculosis in MGIT system was between 2 to 55 days (mean 16.3±10.4 days). Of all samples studied, 17.6% and 3.4% were resistant to Isoniazid and rifampin, respectively, and 3.4% (5 samples) were MDR (CI 95% 1-6%). The turnaround time required for determining MDR cases was 9.6 days. No statistically significant association was found between the resistance to the drugs and none of the factors including sex, age, type of clinical sample, and positivity of the smear. Conclusion: The prevalence of MDR in the studied region was determined to be 3.4% which is similar to the country-wide evaluations. The turnaround time for Mycobacterium growth and anti drug susceptibility result can be shortened by MGIT method.

Abstract
Abstract Background and Objective: Group B streptococcus is one of the agents leading to infantile blood infection and meningitis as well as aggressive infections in pregnant women. The vast use of antibiotics in order to prevent from the diseases caused by this bacterium has led to some concerns about the emergence of drug resistance in Group B streptococcus. Thus, we aimed to investigate Group B streptococcus drug resistance patterns to aid appropriate drug prescriptions. Material and Methods: The study was conducted on 268 pregnant women. Having been transferred to Todd Hewitt broth, the samples were cultured on blood agar and the identity of Group B streptococcus was confirmed through biochemical tests (gram stain tests, the catalase test, CAMP, and sodium hippurate hydrolysis). Results: Of 268 samples, 14 (5.2 percent) showed positive Group B streptococcus culture. All cases (100 percent) were resistant to penicillin, eight (57.15 percent) to erythromycin, 13 (92.2 percent) to clindamycin, three (7.1 percent) to Cefazolin, seven (50 percent) Ceftizoxime and four (28.57 percent) were resistant to Cefotaxime. Three (21.4 percent) were semi-sensitive toward Cefazolin. No resistance was observed toward ampicillin or Vancomycin. Conclusion: The rate of B streptococcus drug resistance to various antibiotics has increased in Iran. Keywords: Streptococcus Group B, Drug Resistant, Pregnant Women, Markazi Province
