Methods: Web of Science, Scopus, and PubMed databases were systematically explored.
Objective: This study investigated the effect of photodynamic therapy on chronic periodontitis patients and then evaluated the microbial, immunological, periodontal, and clinical outcomes. The significant effects of photodynamic therapy obtained by and studies have made it a popular treatment for periodontal diseases in recent years. Photodynamic therapy is a novel bactericidal strategy that is stronger, faster, and less expensive than scaling and root planing.

The aim of our study was to investigate the presence of major virulence factor genes, ability of biofilms formation, and correlation between presence of Legionella isolates and temperature, pH, and residual chlorine of water. Hundred water samples were collected from nine hospitals in Tehran, Iran.

Methods: An anti- phage was isolated from sewage and visualized by electron microscopy, the vB_EfsS_V583 (V583) host range was determined by spot test on 13 clinical strains. Inhibition and degradation experiments were designed to investigate the effect of phage on biofilm.
Objective: This case-control study was designed to compare the composition of the predominant oral bacterial microbiome in Alzheimer's disease (AD) and control group.
Subject: A total of 30 adult participants (15 AD and 15 healthy individuals) were entered in this study. The composition of oral bacterial microbiome was examined by quantitative real-time polymerase chain reaction (qPCR) using bacterial 16S rDNA gene.
Problem: Enterococcus faecalis is a common microbial semen contaminant. Although virulence factors and biofilm formation have often been analyzed in Enterococcus spp., there is little information about these features in isolates obtained from the genitourinary tract.
View Article and Find Full Text PDFBackground And Objectives: Due to the reduced susceptibility of clinical strains in hospitals to various antimicrobial agents, the importance of antimicrobial susceptibility testing (ASTs) has increased. This study aimed to investigate the toxin gene profiles and the antimicrobial resistance of isolated from hospitalized patients suspected of having infection (CDI) in Tehran, Iran.
Materials And Methods: The stool samples were obtained from a hospitalized patients.
Background: One of the causes of male infertility is Genital tract infections (GTI). Considering the importance of GTI, widespread recognition of them seems necessary. we aimed to characterize and compare semen microbial populations in fertile and infertile men who referred to an infertility clinic in Yazd, Iran.
View Article and Find Full Text PDFBackground And Objectives: An important leading cause of the emergence of vancomycin-resistant enterococci, especially , is the inefficiency of antibiotics in the elimination of drug-resistant pathogens. Consequently, the need for alternative treatments is more necessary than ever.
Materials And Methods: A highly effective bacteriophage against vancomycin-resistant called vB-EfmS-S2 was isolated from hospital sewage.
Background: Bacterial spores are among the most efficient vaccine delivery vehicles. Because of their safety and efficacy, spores are increasingly used in this regard. The negatively charged surfaces of the spores allow antigens to be adsorbed onto these structures.

Given the high morbidity and mortality, as well as the cost of management, particularly in developing countries, burn injuries are considered important health concerns. Owing to the increased rate of resistance against antibiotics, this study aimed to isolate strains from burn patient's wounds by analyzing antibiotic susceptibility and genetic profiling.

Antimicrobial peptides labeled with gamma-emission radio nuclides are important diagnostic radiotracers in nuclear medicine. This study was conducted to evaluate the potential of a Tc-labeled MicrocinJ25 (MccJ25) antimicrobial peptide analog for early detection of infection.

Auto-infection cycle can be resulted in high parasitic load, especially in immunocompromised hosts. Because of low sensitivity of stool culture and stool-based microscopy techniques, detection of antibodies in patient's sera can be an alternative diagnostic technique for detection of the nematode.

The aim of this study was to evaluate the effect of improved formulation of chitosan-alginate microcapsules of Bifidobacterium strains on serum triglycerides, cholesterol, HDL, and LDL in mice.
Methods: Five approved probiotic strains of Bifidobacterium were tested for anti-proliferative effect and interleukin-8 induction on HT-29 cell lines.
Background: is an opportunistic human pathogen that causes severe acute and chronic nosocomial infections, especially in immunocompromised burn patients. and can lead to severe mortality and morbidity. The emergence of antibiotic resistant infections has created significant challenges in treating these patients.

This study aimed to assess the frequency of spp. and their related virulence factors in foodstuffs in Isfahan, Iran.
View Article and Find Full Text PDFNowadays the most important problem in the treatment of bacterial infections is the appearance of MDR (multidrug-resistant), XDR (extensively drug-resistant) and PDR (pan drug-resistant) bacteria and the scarce prospects of producing new antibiotics. There is renewed interest in revisiting the use of bacteriophage to treat bacterial infections. The practice of phage therapy, the application of phages to treat bacterial infections, has been around for approximately a century.

KPC-producing strains are not only able to hydrolyze carbapenems but are also resistant to a variety of β-lactam and non-β-lactam antibiotics. The present study evaluated the prevalence of in infections and determined the antimicrobial susceptibility of the isolates.
