Abstract
Backgraund & Objectives: Asymptomatic urinary tract infection (AUTI) is common in childhood and will lead to renal scars. Since the prevalence of AUTI has not been studied in Ardabil, this study set out to determine the prevalence of AUTI among primary-school children of Ardabil. Methods: In this descriptive-analytical study, 470 cases were selected randomly from 40,000 primary school students. The data were collected with completing a questionnaire. The cases with symptomatic urinary infection and those with discontented parents were omitted. Midstream urine was collected and sent to laboratory for analysis and culture. Colony count ≥ 100,000 CFU / ml and higher was considered as UTI and the prevalence of this complication in the samples was studied. Results: Of 470 subjects, 16 ones were ruled out due to urinary symptoms or parents’ discontent, and the study continued with 454 students (238 girls and 216 boys). 19 students (4.2%) had positive culture (13 girls and 6 boys). Prevalence of AUTI was 5.5% in girls and 2.8% in boys. In this study only seven cases (36.8%) had pyuria ( WBC>5). Conclusion: The high prevalence of AUTI specially in girls is important. Regarding the known complications of AUTI, other researches seem to be necessary to determine the causes as well as ways to prevent and treat it.

Abstract
Background & Objectives:Urinary tract infection (UTI) ranges from asymptomatic bacteriuria to severe renal infection with sepsis. Urinary tract infection can cause many complications as abscess, hypertension, renal failure, renal scar, reflux and so on. Since there is no general agreement on the administration of additional fluid (1.5 times maintenance) on the early treatment of UTI on this study was conducted to see the effect of additional fluid. Methods:206 children with UTI who were admitted in Amir Kabir Hospital of Arak from March 2005 to March 2006, were divided into two groups of 103. One group received the usual amount of maintenance fluid and the other 1.5 times of maintenance. The course of resolution of dysuria, frequency, malodorous urine, abdominal pain and fever were compared in the two groups. Patients' urine culture was performed on the second day, 7-10 days, and 90 days after admission. Patients were matched according to their age and sex. Those who presented with azotemia were excluded from the study. Results: Receiving additional fluid had a significant effect on the malodorous urine dysuria. However, it had an inverse effect on the treatment of fever and urinary frequency and it made them even last longer. In other areas like abdominal pain and urine culture in 3 stages there was no difference. Conclusion: It seems that intake of excessive amounts of water has no significant effect on the results of the UTI treatment.

Abstract
Background & Objectives: Nowadays, appearance of ESBL producing bacteria is medical problem in the treatment of infections. Uropathogenic Escherichia coli like many other bacteria can produce these types of enzymes. T he assessment of the ESBL production by clinical isolates is not done routinely in laboratories. The aim of this study was to determine the prevalence of ESBL producing E.coli and its antibiotic resistance pattern in Kermanshah. Methods: This cross - sectional study was done on 200 Uropathogenic E. coli strains isolated from people in Kermanshah. Sensitivity of isolates to different antibiotics was determined by disk diffusion test and ESBL production was assessed by DDST method. Results: The E. coli strains showed high susceptibility to imipenem (100%), amikacin (97%), nitrofurantoin (95.5%), gentamicin (85%), cefepime (75%), ceftazidime (74%), ofloxacin (73.5%), ciprofloxacin, ceftriaxone and aztreonam (71%) and cefotaxime (70%) respectively. The highest resistance was seen to ampicillin (77%), carbenicillin (76%), pipracillin (74%) and SXT (62.5% ). Resistance rate to third generation cephalosporins was 63-75%. Fifty seven isolates (27%) were ESBL producers and 47 isolates (87%) produced all four types of ESBL enzymes. Conclusion: There are some similarities and differences in the antibiotic resistance pattern and ESBL production among the isolates in different areas of Iran and other countries. Identification of ESBL producing bacteria and determining its antimicrobial resistance pattern are recommended to effective treatment of infections.

Abstract
Background & objectives: Urinary tract infections (UTIs) caused by extended-spectrum beta lactamase (ESBL)-producing bacteria have become a growing problem worldwide. The aim of this study was to investigate the prevalence of ESBL-producing bacteria in urine samples of hospitalized patients in Imam Khomeini hospital of Ardabil over a period of October 2011 to August 2012. Methods : A total of 400 urinary pathogens isolated from urine samples were included in the study. All isolates were identified by routine biochemical methods and antimicrobial susceptibility testing carried out by Kirby-Bauer method. Confirmatory test for production of ESBLs was performed by the combination disk tests. The results were interpreted according to the recommendation of CLSI. Results : Of 400 isolated bacteria, 267 were E.coli, 39 Klebsiella pneumoniae, 17 Klebsiella oxytoca, 16 Enterobacter cloacae, 15 Enterobacter aerogenese, 6 Enterobacter agglomerans, 8 Enterobacter sakazakji, 3 Citrobacter froundi, 2 Citrobacter diversus, 3 Proteus mirabilis, 4 Edvardsiella tarta, 3 Serratia marcesecens and 17 Morganella morganii all of which then were analyzed. ESBL was detected in 36.75% (147) of isolates. Eighty nine E.coli cases (77.4%), 15 Klebsiella pneumonia (13.04%), 2 Klebsiella oxytoca (1.74%), 3 Enterobacter aerogenese (2.6%), 4 Enterobacter cloacae (3.5%), 1 Citrobacter ferundi (0.86%), and 1 Morganella morganii (0.86%) were detected as ESBLs producers, respectively. Conclusion : Based on the results of this study, broad-spectrum beta-lactamase production in bacterial strains isolated from patients with urinary tract infection was very high and almost 40% of all bacterial species isolates were ESBLs producers. Because of the high prevalence of ESBL-producing bacteria in the urinary tract infections in hospitalized patients of our area, we would strongly suggest that the ESBL production should be considered in these patients.

Abstract
Background & objectives: Urinary tract infection (UTI) is one of the most common types of human infections and Escherichia coli and Klebsiella pneumonia are the main causes of urinary tract infection among the gram negative bacteria. The prevalence of extended-spectrum β-lactamases (ESBLs) among these bacteria and hence resistant strains to β-lactam antibiotics have increased in recent decades. Several types of extended-spectrum β-lactamases, such as TEM, SHV and CTX-M have been identified, which are prominently present in the strains of E. coli and K. pneumoniae. The objective of this study was to determine the prevalence of TEM and SHV genes in E. coli and K. pneumoniae isolates of urinary tract infections by using phenotypic and molecular (PCR) techniques in microbiology laboratory at medical school of Tabriz Islamic Azad University.
Methods: In this cross-sectional descriptive study, 50 isolates of E. coli and 50 isolates of K. pneumoniae collected from urinary tract infections from out-patients in Tabriz. Antibiotic sensitivity patterns of isolates were studied against 14 antibiotics by disk diffusion test (Kirby Bauer) and also confirmatory tests were performed using combined antibiotic tests. Finally TEM and SHV genes were investigated using molecular methods (PCR).
Results: Twenty five isolates (25%) out of 100 bacterial isolates were identified as ESBL-producing isolates of which 13 isolates (26%) were E. coli and 12 isolates (24%) were K. pneumoniae. The TEM and SHV genes were detected in 2% and 4% of E.coli and 0% and 2% of K. pneumoniae isolates, respectively.
Conclusion: The presence of these genes among our isolates confirmed ESBL genes in these medically important bacteria leading to resistance against β-lactam antibiotics which are routinely used in their treatments. The low frequency of the studied genes could be because of the source of our isolates from out-patients which are not generally exposed to antibiotics

Abstract
Background and objectives: Urinary tract infection (UTI) is the most prevalent infection and Escherichia coli (E. coli) is one of the main causes of UTI worldwide. Integrons are mobile genetic elements considered to be responsible for dissemination of multi-drug resistance infections. Therefore, the aims of this study were to investigate the antibiotic resistance patterns and distribution of class I, II and III integrons among E. coli isolated from patients.
Methods: In this descriptive cross-sectional study, from Jun 2020 to March 2021, in total, 70 non-duplicate strains of E. coli were isolated from patients with UTI referred to Amiralmomenin hospital, Zabol, Iran. Antibiotic resistance patterns were determined using Kirby-Bauer’s disk diffusion method and Clinical and Laboratory Standards Institute (CLSI) guidelines. Class I, II and III integrons were detected using polymerase chain reaction (PCR).
Results: The isolates showed high resistance toward ampicillin (77.1%), trimethoprim- sulfamethoxazole (58.5%) and ceftriaxone (35%), whereas were mostly susceptible to meropenem (97%). Based on results of PCR, 34 (48.6%) and 3 (4.3%) isolates were classified as class I and class II integron-positive strains, respectively.
Conclusion: Resistance rate to ampicillin, ceftriaxone and trimethoprim-sulfamethoxazole was at a high level and their prescription should be restricted. Class I integron is widely distributed among E. coli isolates and play a crucial role in the emergence of antibiotic resistance

Abstract
Background & objectives: Urinary tract infection is still one of the most common diseases that affect pregnant women. The aim of this study was to determine the impact of sexual hygiene behaviors on urinary tract infection in pregnant women.
Methods: A case-control study was conducted on 100 pregnant women with urinary tract infection (case group) and 150 pregnant women without urinary tract infection (control group) in health centers of Ardabil city in 2020. Purposive sampling was done in 6-10 weeks of pregnancy. The information was collected through a researcher-made questionnaire. SPSS 21 software was used for statistical analysis of data. The odds ratio (OR) of infection in both groups was estimated by logistic regression.
Results: Sexual health behaviors in the majority of women of the case group (47%) were average (with score of 50.1-66), but in the majority of the control group (49.33%) were good (with score of 66.1-84) (p<0.001). Sexual intercourse 3 or more times in a week in the last 30 days was significantly higher in the case group than in the control group (p=0.001). Spouse bathing before sexual intercourse was less in women in the case group than the control group (p=0.022). Statistically significant differences were observed in Pre-coital voiding (p=0.04), Post coital voiding (p=0.02) and post-coital bathing (p=0.03) in the two groups.
Conclusion: Sexual hygiene behaviors play an important role in preventing or contracting urinary tract infections. Therefore, training and improving hygiene behaviors in women and their spouses is an effective step in reducing urinary tract infections.
