Clostridium perfringens has emerged as an important cause of antibiotic-associated diarrhea (AAD), particularly in the hospital environment. Here we investigated prevalence and molecular epidemiology C. isolated from 2280 fecal samples Iranian diarrheal patients suspected having AAD. Overall, AAD was diagnosed 13.3% (303/2280) associated with advanced age (>50 years, P = 0.001). A total 106 isolates were cultured (n 68) non-AAD 38) groups, toxinotypes F comprising 84% 16% isolates,...
Purpose: Fecal microbiota transplantation (FMT) is an effective treatment option for patients with recurrent Clostridioides difficile infection (rCDI). However, there a paucity of evidence regarding its efficacy and safety in rCDI concurrent inflammatory bowel disease (IBD). Here, we present single-center experience FMT Iranian IBD. Patients Methods: Eight established IBD (7 ulcerative colitis 1 Crohn's disease) who underwent at least one via colonoscopy were enrolled this study....
This study was done to evaluate the effects of different concentrations
The dramatic upsurge of Clostridioides difficile infection (CDI) by hypervirulent isolates along with the paucity effective conventional treatment call for development new alternative medicines against CDI. inhibitory effects curcumin (CCM) and capsaicin (CAP) were investigated on activity toxigenic cell-free supernatants (Tox-S) C. RT 001, 126 084, culture-filtrate ATCC 700057.Cell viability HT-29 cells exposed to varying concentrations CCM, CAP, Tox-S was assessed MTT assay....
Fish-packaging technology is essential in maintaining the quality and shelf life of fish as a valuable perishable food. This research was performed to evaluate influence polylactic acid-nanochitosan (PLA-NC) films containing Bunium persicum oil (BPEO) (0, 0.3, 0.6, 0.9%) on microbial, chemical, organoleptic characteristics rainbow trout fillets during storage under refrigeration for 13 days. On last day period, wrapped with PLA-NC BPEO, microbial population declined by at least 1 log CFU/g...
Root canal-treated teeth are weaker than vital and more susceptible to fractures. Therefore, special precautions should be adhered to, such as the use of various types cast or prefabricated posts. Regarding effect post material on fracture resistance teeth, aim this in vitro study was evaluate non-precious gold color alloy (NPG) nickel-chrome (Ni-Cr) posts endodontically treated teeth.In study, 30 freshly extracted single-rooted premolar were randomly divided into two groups. After root...
Introduction: This research was carried out to compare the effects of 0.525% and 5.25% NaOCl, 2% H 2 O 2, 16-mg/mL propolis on additional silicone impression materials contaminated with Candida albicans at 5- 10-minute exposure times, evaluate hypotheses this study that can be used for disinfecting dental impressions. Materials methods: A total 122 impressions were prepared. Two samples considered negative controls, rest C. fungal species disinfected , propolis, 96% ethyl alcohol 5 10...
Abstract Background and Aims: Infectious bronchitis virus (IBV) is the causative agent of avian infectious bronchitis, which characterized by respiratory, reproductive, renal signs. IBV a highly variable with large number genotypes. S1 gene sequencing has been used for molecular epidemiological studies genotypic characterization IBV. To better understand epidemiology in Iran, we sequenced field isolates, total 40 tracheal kidney tissue specimens from different commercial broiler flocks East...
To detect and characterize Escherichia coli (E. coli) O157:H7 in feral pigeons Qom province, Iran. In this survey, 290 cloacal samples were obtained from trapped province. Microbiological, biochemical serological examinations done to the E. O157:H7. Isolates subjected multiplex polymerase chain reaction for detection of stx1, stx2, eaeA hlyA genes. Four (1.38%) positive by using O157 H7 antisera only one strain isolated showed presence The results present survey revealed that province had...
BACKGROUND: Avian infectious bronchitis is considered as an important viral disease worldwide. Genotyping based on the S1 subunit of spike protein gene causative agent, avian virus, can be used to classify IBV isolates. Objective: This survey was carried out characterize virus (IBV) genotypes circulating in Iran and determine their prevalence rate. METHODS: In this survey, 100 samples trachea were collected from broiler chickens suspected during 2015 2016. Nested polymerase chain reaction...
