Nano-silver and nano-titanium oxide films can be coated over brackets in order to reduce bacterial aggregation friction. However, their antimicrobial efficacy, surface roughness, frictional resistance are not assessed before. Fifty-five stainless-steel were divided into 5 groups of 11 each: uncoated brackets, with 60 µm silver, 100 titanium, titanium. Coating was performed using physical vapor deposition method. For friction test, three from each group randomly selected tested. scanning...

These strains were identified by standard biochemical tests and serology. Antibiotic...

Multi-drug-resistant (MDR) Acinetobacter baumannii has become a major global healthcare concern due to its opportunistic infections and high antibiotic resistance. This investigation is intended investigate curcumin's potential anti-bacterial antibiofilm impacts on MDR A. present promising strategy for fighting against caused by this pathogen. cross-sectional comprised 34 clinical isolates. The Kirby-Bauer disc diffusion method evaluated the sensitivity of isolates multifaceted agents....

Genetic determinants conferring resistance to macrolide, lincosamide, and streptogramin B (MLSB) via ribosomal modification such as, erm, msrA/B ereA/B genes are distributed in bacteria. The main goals of this work were evaluate the dissemination MLSB phenotypes genotypes methicillin-resistant Staphylococcus aureus (MRSA) isolates collected from clinical samples.A total 106 MRSA studied. Isolates recovered 3 hospitals Tehran between May 2016 July 2017. prevalence MLSB-resistant strains...

<b>Context</b>: One of the common oral bacterial infectious diseases is dental caries. Control plaque formed by <i>Streptococcus mutans and Streptococcus sobrinus</i> leads to prevention treatment Chitosan (1-4, 2-amino-2-deoxy-b-D-glucan), a deacetylated derivative from chitin, an antimicrobial polysaccharide that exerts broad-spectrum activity against pathogenic bacteria has been suggested as preventive therapeutic material for caries.<br><b>Aim</b>: The aim this investigation whether...

Infections due to carbapenem-resistant Enterobacteriaceae (CRE) are associated in patients with urinary catheters alarming rate of emergency status. The aim this study is investigate the molecular causes carbapenem resistance among UPEC as well antimicrobial trends. Additionally, potential isolates produce biofilms, addition their clonal and genetic diversity, was investigated. Material Methods. A cross-sectional accomplished on a collection 76 non-duplicate obtained from CAUTIs May 2021...

Infection is a serious problem for patients after implantation surgery, which difficult to treat with antibiotic therapy. The present study was developed evaluate and compare the antibacterial properties of hydroxyapatite/bioactive glass (HA/BG) fluorapatite/bioactive (FA/BG) nanocomposite foams as cellular scaffold use in bone defects by two macrodilution disk diffusion methods.Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans were cultured brain heart infusion broth medium...

Abstract Objective Rapid, reliable, and affordable detection of Brucella species via the molecular methods remains a challenge. In recent years, loop-mediated isothermal amplification (LAMP) is functional nucleic acid technique offering substitute to polymerase chain reaction (PCR). So, we compared LAMP assay with conventional PCR for identification common in Iran. this study, was comprehensively evaluated against method. A group specific primers were used amplify highly fragment from...

Otomycosis is an external ear canal infection caused by various fungi. This disease prevalent in some tropical and subtropical regions or countries.Given the crucial role of fungal agents treatment disease, aim present study was to identify fungi patients with otomycosis admitted hospitals Babol City, Iran.This included 56 otomycosis. After removal infectious samples, them were placed on slides for direct examination also a portion plated Sabouraud dextrose agar chloramphenicol growth. The...

We investigated the integron types and their relation with antibiotic resistance among A. baumannii isolates collected from intensive care unit patients, Babol, north of Iran.In this cross-sectional study, a total 73 bronchoalveolar lavage samples were obtained patients in ICU. Susceptibility testing was performed by disk diffusion method. Types integrons identified an integrase gene PCR.In total, 47.9% recovered BAL samples. All resistant to ceftazidime. 91.4% 58.3% MDR XDR, respectively....

Aims and Objectives: The present work aimed to evaluate the frequency of aminoglycoside- modifying enzymes encoding genes in E. faecalis faecium their antibiotic resistance profile. Methods: A total 305 different clinical samples were subjected for identification susceptibility test. high-level aminoglycoside was identified by MIC Kirby Bauer disc diffusion method. prevalence aac (6')-Ie-aph (2'')-Ia, aph (3')-IIIa ant (4')- Ia determined multiplex- PCR. In total, 100 enterococci strains...

Background: Due to the importance of antibiotic resistance in E.coli and possible role integrons creating resistance, this study was performed survey class 1 integron E. coli strains their three routinely used antibiotics.Methods: In cross-sectional study, 100 were isolated from patients with Urinary tract infection.After diagnosis bacteria, genomes extracted.Then, presence evaluated by using PCR.Antibiotic susceptibility testing method, micro dilution broth according standard CLSI2010.Data...

This study sought to assess the inhibitory effect of chitosan-containing sealants against Streptococcus mutans.The antibacterial activity resin sealant was evaluated by direct contact test following addition 0, 1, 2, 3, 4, and 5 wt% chitosan.
