Abstract
Background and Objective: Bacterial infectioins in particular meningitis, pneumonia and septicemia are still some of the most causes of mortalities in children.The aim of present study was to identify the most common bacterial agents causing infectionis in children under 14 and detection of antibiotic resistance paterns.
Material and Methods: During two years,1897samples were obtained from the patients suspected bacterial infectioins. They were investigated for bacterial cultures, age, sex and antibiogram patterns. The species were identified by biochemical and serological methods.
Results: Of 1897 samples, 563 (29.6%) had positve bacterial culture. Of these 74.7% were gram negative and 25.3% gram positive . The most common species were Escherichia coli(34.1%), Staphylococcus aureus (17.1%), Psuedomonas aeroginosa (12.4%), Kelebsiella (11%) and Staphylococcus epidermidis (5.7%). The most effective antibiotics against both gram positive and gram negative bacteria were ceftriaoxne, nitrofurantoin, nalidixic acid, amikacin and gentamycin.
Conclusion: The gram negative bacteria in particular Escherichia coli, Psuedomonas aeroginosa and Kelebsiella are the predominant causes of bacterial infections in children under 14 in these regions. Most species showed a high relative resisitance to routine antibiotics such as ampicillin, trimethoprim and chloramphenicol.

Abstract
Abstract Background and Objective: The prevalence of different bacterial species and antibiotic resistance varies according to geographical conditions. Hence, we aimed to identify the prevalence of bacterial agents isolated from the urine culture and also investigate the antibiotic susceptibility of bacteria. Material and Methods: This cross-sectional study conducted on 7200 urine samples to identify the bacteria causing infections, using differential tests. The antimicrobial susceptibility was performed via disk diffusion method according to the Clinical and Laboratory Standards Institute (CLSI). Results: The most common bacteria were Escherichia coli (736 61.1%) and Klebsiella pneumonia (128 10.6%) and Enterococcus faecalis, (88 7.3%). The highest antibiotic susceptibility was related to Ciprofloxacin (174 14.45%) and the lowest to Amoxicillin (795 62.02%). Conclusion: Owing to the lowest resistance, it is recommended that Ciprofloxacin be used as the first line of treatment. In addition, Amoxicillin and Ampicillin should be used the least during primary treatment of urinary tract infections. Keywords: Antibiogram, Bacterial Resistance, Urine Culture

Abstract
Abstract
Background and Objective: Helicobacter pylori (H. Pylori) infection is related to chronic gastritis, peptic ulcer, duodenal ulcer and gastric cancer. Thus, identification and treatment of the infection have a considerable importance. The aim of this study was to compare three methods of Histopathology, Culture and Rapid Urease test (RUT) in identification of H. Pylori in gastric biopsy specimens.
Material and Methods: The participants were 153 patients (64 women and 89 men) suffering from digestive complaints, who referred to the endoscopy department of Shahid Beheshi Hospital in Hamadan, Iran. Three gastric biopsy samples were collected from each patient and examined by standard RUT, Histopathology and culture methods for diagnosis of H. Pylori.
Results: Out of 153 patients, 69.9%, 27.4% and 2.6 % had gastritis, gastric ulcer and gastric cancer, respectively. The rate of infection with Urease test, culture and histology were identified 49.7%, 54.2%, and 89.5%, respectively. The sensitivity and specificity of the RUT result at first hour and after the first up to 24 hours were 55.4% and 80%, and 55.4% and 66/7%, respectively. The sensitivity and specificity of culture method were 60.6% and 100%, respectively.
Conclusion: Based on the results, Histopathology method has a more sensitivity than both Culture method and rapid urease test for diagnosis of H. Pylori, and RUT is more specific when done in the first hour rather than after the first hour.
