Introduction: Diabetes is the most common and important diseases in the world, and diabetic patients are at high risk of infection. Due to the high prevalence of diabetes and risks of urinary tract infections, ccauses of urinary tract infection and the proper way to treat it acutely felt Material and methods: In this study, 353 urine samples of diabetic patients cultured and by using biochemical tests were examined. After DNA extraction, PCR test for definitive diagnosis of bacteria and the antibiogram test was carried out. Results: Urinary tract infection in diabetic patients 28.3% was reported. Asymptomatic bacteriuria 22.1% and symptomatic bacteriuria 6.22% was reported. The most common bacteria that cause urinary tract infections in patients were respectively Escherichia coli, Klebciella pneumonia, Proteus, Staphylococcus saprophyticus, Acinetobacter, Citrobacter, Enterobacter, Pseudomonas aeruginosa and Providencia. Conclusion: Given that bacterial population of urinary tract infections in diabetic patients, similar to non-diabetic patients, so antibiotic treatment in diabetic patients is alike with and non-diabetic patients. Keywords: bacteriuria, Diabetes, urinary tract infection, antibiotic resistance, PCR. Manuscript profile

Background & Aim: Klebsiella pneumoniae is one of the most common gram-negative bacteria in the development of nosocomial infections, in particular urinary tract infections, which has been resistant to antibiotics in recent years. The aim of this study was to determine the pattern of antibiotic resistance in the most common capsule types of this bacterium in Zarinshahr city of Isfahan. Material and Methods: 29 strains of Klebsiella pneumoniae isolated from urinary tract infections in patients admitted to different parts of Zarinshahr Hospital in summer 2016 to summer 2017 were selected. After confirmation of phenotypic and genotype and determination of capsule types in them, antibiotic resistance pattern in isolates was determined using Kirby-bauer method, according to the CLSI standard, on the Muller Hinton Agar, 13 antibiotics were determined. Frequency of antibiotic resistance gene encoding genes including tetA, cmlA, Cat1, blaSHV, sul1, aac (3) -IV, aadA 1, qnr CITM, dfrA1, and tetB genes in isolates was determined by PCR method. Results & Conclusion: Serotype K2 with 74.51% frequency was the most commonly known capsule serotype known in isolates. All isolates had multiple antibiotic resistance and in addition to penicillin, their antibiotic resistance was the highest (10.93%) and tetracycline (44.30%) respectively. The tetA and sul1 genes with the frequency of 86.75% and 41.72% were the most common, and the two cat1 and cm1A genes with a frequency of 89.60% and 44.10% were the least common antibiotic resistance genes in Klebsiella pneumoniae strains isolated from urinary tract infections.

Background and Objective: Urinary tract infection (UTI) is one of the most common hospital infections acquired by colonization of uropathogenic E. coli in host musocal epithellium and damages to host tissue. The ability to constitute biofilm plays an important role in virulence of the bacteria. Materials and methods: In this research 51 E. coli strains isolated from diabetic patients having UTI symptoms collected and approved using biochemical tests and molecular technique. In vitro biofilm formation by these isolates was determined using the 96-well microtiterplate test. And the presence of fimH, pap, sfa and afa virulence genes was examined. Results: Among 51 Ecoli isolates, 46 (90.16%) were able to make biofilm. The frequency of fimH, pap, sfa and afa genes in isolations having the ability to create strong biofilm reported respectively 90%, 80%, 80% and 10% reported, The frequency of fimH, pap, sfa and afa genes in isolations having the ability to create weak biofilm reported respectively 83.33%, 75%, 15% and 41.66% reported. Discussion: The results of this study showed that the prevalence of fimH and pap genes among UPEC strain is high. Conclusion: The findings indicated the importance of virulence genes in Escherishia coli isolates producing biofilm Manuscript profile
