Generally, bacteria co-exist setting up communities associated to solid superficies, this is to which we refer as biofilms that serve as a survival strategy. This type of formation cause serious sanitary problems for both humans and animals. Nowadays, chemical or natural compounds able to block this formation are looked for. In this project, we have evaluation of antimicrobial effects of Rosemary and Withania somnifera extract prepared by ultrasound waveform on Escherichia coli biofilm isolated from urinary tract infection. Rosemary and Withania somnifera extracts were obtained by using rotary devices. E. coli was collected from the patients being cured in Zabol hospitals. The least hindering and killing concentration of the samples were calculated by lowering their densityin sinks. The growth and biofilm formation of strains were determined by microtiterplate method. Data were analyzed statistically by determination of significant difference using analysis of variance (ANOVA) test. All tests were analyzed at the significance level P less than 0.05. The results revealed that the concentrations of 5 and 10 mg/mL are the most restrain in the biofilm formation of the isolated plates. Rosemary and Withania somnifera extracts have considerable antimicrobial and ant biofilm effect on the samples of the E. coli resistant to antibiotics.

Abstract Introduction: Urinary tract infection is the most frequently diagnosed kidney and urologic disease. Methodology: Whether the Escherichia coli strains responsible for urinary tract infection (UPEC) carry virulence properties of diarrheagenic E. coli (DEC), 56 UPEC strains were examined for the presence of DEC and UPEC characteristics (e.g. biofilm formation, hemolysis activity, virulence genes). Results: Among 56 UPEC strains, 21 showed capable of biofilm formation and only 5 showed hemolysis activity on sheep blood agar. In Multiplex PCR on assessment of virulence genes related to uropathogenesis; 42% was found positive for papC gene, 27% was fim1 positive, 11% was afa positive and none was found positive for sfa. Most of the isolates were found carrying none of eight diarrhea associated genes (e.g. estA, eltB, vt1, vt2, eaeA, ea, ial and bfpA) as expected. Only seven isolates were found to harbor these genes: five genes i.e., vt2, ial, eltB, bfpA and ea were found in five different isolates and two isolates were positive for estA, among these two, one was found positive for fim1, papC along with estA, a UPEC strain containing virulent gene of ETEC strain. One isolate was found carrying fim1 and vt2 showing the property of EHEC and another isolate was found positive for fim1 and ial, the characteristic of EIEC. One isolate harboring bfpA gene characterized as EPEC and the another one was found to harbor ea gene, characterized as EAEC. Conclusions: This study observed that most UPEC strains are unique to uropathogenesis, still very few may carry the diarrheagenic property.

 During the period from September 2016 to December 2017,135 urine samples were collected from urinary tract infection patients attending to AL-Zahraa Hospital in AL-Najaf Governorate. The present study was conducted to isolate and identify Candida spp. isolated from urinary tract infection patients by different methods including direct examination, laboratory culture, biochemical test and by modern techniques (Api Candida kit) and determine the virulence factors phenotypic to Candida spp which involved (biofilm formation,phospholipase and germ tube). The percentage of females to males was as following, female (84) 62.2 % (21) infected and male (51) 37.8% (1) infected with all age categories. The results in this study are explain that is some Candida spp. such as C. albicans, have high susceptible to eugenole follow by phenol and umbellulone. The efficiency of some chemical substances such as (eugenole,umbellulone, and phenol) was evaluated to inhibit the growth of Candida ssp as well as some virulence factors such as biofilm formation,germ tube and phospholipase,which were studied in this research. Statistically analysis results have been significance difference between the results of the substance concentrations and the concentrations of the different other substances.
