The role of microbiota in colorectal cancer.

Cancer is one of the most important causes of death throughout the world, and the mortality rate is increasing significantly due to the aging of the population. One of the most common types of cancer is colorectal cancer (CRC). Human microbial ecosystems use metabolism to make important impacts on the body physiology.

Occurrence of plasmid-mediated quinolone resistance genes in Pseudomonas aeruginosa strains isolated from clinical specimens in southwest Iran: a multicentral study.

This study aimed to assess the presence of qnrA, qnrB, qnrC, qnrD, qnrS, qepA, and aac(6')-Ib-cr determinants as well as quinolone resistance pattern of clinical isolates of P. aeruginosa in Ahvaz, southwest Iran. A total of 185 clinical isolates of P.

Associations between seroprevalence of and ABO/rhesus blood group antigens in healthy blood donors in southwest Iran.

Objective: To investigate correlations between ABO/rhesus (Rh) blood group antigens and anti- and anti-cytotoxin-associated gene A (CagA) seropositivity in blood donors.

Methods: A total of 311 blood donors were enrolled. ABO and Rh blood groups were determined using hemagglutination tests.

Prevalence of Extended-Spectrum Beta-Lactamase-Producing Causing Bloodstream Infections in Cancer Patients from Southwest of Iran.

Introduction: This study aimed to evaluate the frequency rate of extended-spectrum beta-lactamase-producing (ESBL-PE) causing bloodstream infections (BSIs) in cancer patients referred to one of the major referral hospitals in Ahvaz city, southwest Iran.

Materials And Methods: In this study, 1700 blood cultures were collected from 610 cancer patients suspected to have BSI from October 2016 to August 2017 referred to the Shafa cancer hospital, Ahvaz, southwest of Iran. The blood culture bottles were incubated aerobically at 35-37ºC for 24 hours and then sub-cultured on routine microbiology culture media.

Investigation of SCCmec types I-IV in clinical isolates of methicillin-resistant coagulase-negative staphylococci in Ahvaz, Southwest Iran.

Today methicillin resistant coagulase-negative staphylococci (MR-CoNS) are important in terms of causing significant nosocomial infections. Besides, MR-CoNS are confirmed as the reservoir of SCCmec elements that carry mecA (methicillin-resistant) gene. Hence, the present study was designed to evaluate the susceptibility pattern, prevalence and diversity of SCCmec types I, II, III, and IV in MR-CoNS strains.

Loop-mediated isothermal amplification for detection of in respiratory specimens of hospitalized patients in Ahvaz, southwest Iran.

Background: Legionnaires' disease is an important public health problem that can cause substantial mortality and morbidity. Legionnaires' disease-risk estimation may be compromised by uncertainties in -detection methods. The aim of this study was the detection of in respiratory specimens of hospitalized patients with respiratory symptoms by culture, PCR, and loop-mediated isothermal amplification (LAMP) methods.

Antibiotic resistance pattern and molecular characterization of extended-spectrum β-lactamase producing enteroaggregative isolates in children from southwest Iran.

Introduction: Enteroaggregative (EAEC) has been implicated as an emerging cause of traveler's diarrhea, persistent diarrhea among children, and immunocompromised patients. The present study aimed to investigate the prevalence of antibiotic resistance, extendedspectrum β-lactamase (ESBL) production, and virulence factors of EAEC isolates obtained from Iranian children suffered from diarrhea.

Materials And Methods: In this cross-sectional study, from March 2015 to February 2016, 32 EAEC isolates were collected from fecal samples of children aged <12 years with diarrhea in southwest of Iran.
