Materials and Methods: In the present study, 207 den...

[ 2 ] - Comparison of the Effect of Phenylalanine Arginine Beta Naphthylamide (PAβN) and Curcumin on Minimum Inhibitory Concentration of Aminoglycosides on Pseudomonas aeruginosa Clinical Isolates

Background and Objective: Efflux pump inhibitors (EPIs) can block efflux pumps and are helpful in potentiating the activity of aminoglycosides against Pseudomonas aeruginosa. The present study compared the effects of phenylalanine-arginine beta naphthylamide (PAβN) and curcumin on aminoglycoside minimum inhibitory concentration (MIC) on Pseudomonas aeruginosa clinical isolates. Materials and M...

[ 3 ] - Green Synthesis of Silver Nanoparticles with Allium paradoxum Extract and Evaluation of their Antibacterial Activities

  Background and purpose: Microbial resistance against antibiotics is increasingly growing, therefore, it is necessary to develop new remedies. Silver nanoparticles have significant antibacterial properties and synthesis of silver nanoparticles mediated by plant extracts could be considered as an alternative in treatment in various infections. Materials and methods: In this study, silver nano...

[ 4 ] - The Role of aac(6)-IIa and ant(2'')-Ia Genes and the Presence of Class 1 Integrons in Resistance of Pseudomonas Aeruginosa Clinical Isolates against Aminoglycosides

Background and purpose: The aminoglycoside modifying enzymes (AMEs) and class 1 integrons in clinical isolates of pseudomonas aeruginosa are the major factors leading to rapid spread of antibiotic resistance. The aim of the present study was to investigate the frequency of aac(6)-IIa, ant(2'')-Ia, and class 1 integrons in clinical isolates of pseudomonas aeruginosa. Materials and methods: For ...

[ 5 ] - Evaluation of Cell Growth Inhibition of Bifidobacterium Bifidum Cell-free Supernatant Extract on 4T1Tumor Cell Lineage

Background: Cancer is amongst the leading reasons of death in all parts of the world. Breast cancer is also responsible for the largest number of deaths among women population. Several studies confirmed that Bifidobacterium bifidum as a probiotic meaningfully inhibited breast cancer development. The present study aimed to investigate the effect of B. bifidum supernatant on the cell growth inhib...

[ 6 ] - Frequency of MDR and XDR Strains and Antibiotic Resistance Pattern of Acinetobacter baumannii Clinical Isolates in Sari Hospitals, Iran

Background and purpose: The prevalence of antibiotic resistance in Acinetobacter baumannii is increasing worldwide, causing significant clinical problems. This study aimed to determine the antibiotic resistance pattern of clinical A. baumannii isolated from different different wards in Sari hospitals. Materials and methods: This study was performed on 100 clinical A. baumannii isolated from Sa...

[ 7 ] - Antibiotic Resistance Pattern of Bacteria Isolated from Automated Teller Machines in Sari, Iran

 Background and purpose: Nowadays, widespread use of automated teller machines (ATMs), has increased the possibility of contamination of hands due to contact with the surfaces of these devices. This study aimed to investigate the prevalence of bacterial contamination and antibiotic resistance pattern of the isolated bacteria from the keyboard of these devices in Sari, north of Iran. Materials ...

[ 8 ] - Prevalence of MDR, XDR and PDR Phenotypes among Pseudomonas aeruginosa Strains Isolated from Hospitalized Patients in Mazandaran Province, Iran

Background and purpose: Pseudomonas aeruginosa is an opportunistic pathogen and the second leading cause of nosocomial infections, especially in the intensive care unit (ICU), and is responsible for high mortality rates. The aim of this study was to determine the pattern of antibiotic susceptibility and prevalence of multiple drug resistance strains of P. aeruginosa isolated from hospitalized p...

[ 9 ] - Antimicrobial Effect of Kids Dentifrices on Streptococcus mutans and Lactobacillus acidophilus: An In-Vitro Study

Background and purpose: Dental caries is one of the most common bacterial diseases in childhood. Using proper dentifrice is suggested to reduce the incidence of this disease. The aim of this study was to investigate the antimicrobial effects of different brands of children's dentifrice available in Iran’s market on Streptococcus mutans (PTCC1683) and Lactobacillus acidophilus (PTCC4356) strains...

[ 10 ] - Identification of Neuraminidase Gene Mutations of Influenza A/H3N2 Isolates in Mazandaran Province, 2016-2018

 Background and purpose: Influenza is one of the viral infections of the respiratory system, which causes death in high-risk groups every year. The genomic changes of influenza virus make it susceptible to drug resistance, therefore, continuous monitoring of the influenza virus is highly important in order to recognize the efficacy of available drugs. The current study investigated the neuramin...

[ 11 ] - Antimicrobial and Synergistic Effects of Garlic and Cinnamon Extract Compared with Fluoride Varnish on Oral Lactobacillus acidophilus and Streptococcus mutans in Laboratory Conditions

Background and purpose: Garlic and cinnamon extracts, like fluoride varnish, play a role in caries control due to their antimicrobial effect and controlling demineralization. This analytical laboratory study was conducted in 2021 to investigate the antimicrobial effect of garlic and cinnamon extracts compared with fluoride varnish in controlling the infection of oral Lactobacillus acidophilus a...

[ 12 ] - The effect of a topical ointment containing methanol extract of Buxus hyrcana Pojark. leaves on cutaneous wound healing in rats

Introduction: Buxus hyrcana Pojark. has been traditionally used for the treatment of skin disorders including wound injuries and recent studies have shown the therapeutic potential of some Buxus species in healing skin wounds. In this study, the effect of an ointment containing methanolic extract of B. hyrcana leaves was evaluated on the full-thickness wound healing in a rat model. Materials an...
