Abstract
Abstract Mycobacterium genus, including pathogenic and environmental species, is called non-tuberculosis mycobacteria. In this review, we assessed the research about the frequency of non-tuberculosis mycobacteria in Iran. The analyses showed that there are 16 and 28 mycobacterial species isolated in water and soil samples, respectively. The most frequent mycobacterial species in water were M. fortuitum (25.4%) and M. chelonae (25.4%), and in soil it was M. fortuitum (19.7%). The most frequent species in clinical samples was M. fortuitum, too. The frequency of non-tuberculosis mycobacteria in various clinical samples was various, and on average 1.1% of the suspected tuberculosis clients referred to the healthcare centers have non-tuberculosis mycobacteria.

Abstract
Abstract Background and Objective: Along with antibiotics, the use of biological methods to combat bacteria is notably considered. A natural barrier such as amniotic membrane is one of the ways of dealing with bacterial infections. The aim of this study was to determine the antibacterial effect of human amniotic membrane. Materials and Methods: This descriptive study was performed in Dezyani teaching Hospital of Gorgan University of Medical Sciences, Iran. To evaluate the antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli bacteria, 20 amniotic membranes were obtained from postpartum mothers and examined by repeated dilution, diffusion and extraction techniques. Data were collected by observation method and described by mean and standard deviation. Results: The antibacterial activity was found in 15% of the samples against Staphylococcus Aureus and Pseudomonas aeruginosa, while no antibacterial activity was found against E. coli. Given the 15% positive responses, "Diffusion" and "repeated dilution" techniques were more effective in investigating the antibacterial effect of amniotic membrane. Conclusion: The results show the probability of antimicrobial effect of amniotic membrane tissue and it seems that this property can be affected by many factors.

Abstract
Abstract Background and Objective: Klebsiella pneumoniae is one of the agents causing nosocomial infection therefore, we decided to report the prevalence of Klebsiella pneumoniae caused infection. Material and methods: The frequency of Klebsiella in culture media samples of Panje Azar hospital was studied in 2011-2012. After determination of the species with biochemical methods and determination of resistance to third generation cephalosporins, the existence of responsible genes for this resistance was investigated using specific primers. The PCR product for CTX-M gene was sequenced. Results: During the study, 70 isolates of Klebsiella were isolated in that 51 (72.8%) related to three months of November, December and January. Except for the one related to November, other ESBL cases belonged to these three months. Based on molecular investigation of ESBL genes, these isolates at least were in 3 types and had a high frequency in Internal, female and Emergency wards. Conclusion: The present report implied a sudden prevalence of Klebsiella pneumoniae that detected and controlled by a correct monitoring. Keyword: Klebsiella Pneumoniae, ESBL, CTX-M

Abstract
Background and Objective: Bacterial infections are of the leading causes of morbidity and mortality in ICU patients with underlying immunodeficiency. This study aimed to determine the frequency of microorganisms in patients admitted to the ICU of Panje Azar Hospital in Gorgan.
Material and Methods: This cross-sectional study was conducted on the patients admitted in three wards, each having at least 48, of ICU in Panje Azar Hospital in Gorgan. All microbial cultures requested by patients' physician were recorded.
Results: In ICU positive cultures were 53.9%. The number was 16 for Staphylococcus coagulase negative, 15 for Enterococci , 11 for Yeast, 11 for E.Coli, 9 for Enterobacter , 8 for streptococcus, 5 for staphylococcus aureus. The highest percentage was related to coagulase-negative staphylococci (16.5%) and the lowest to Alcaligenes, Diphtheroids, Acremo bacteria , Serratia with one positive case.
Conclusions: the incidence of bacterial contamination in ICU patients compared to other parts of country is not different significant. While it is far from world standard, it is essential that many efforts be done to reduce the level of infection.
