Introduction: Most of the animals reared for food are reservoirs Extended Spectrum Beta-lactamase (ESBL) producing coliforms. ESBL Escherichia coli (E. coli) in chicken meat increasing worldwide. Since consumption meals is higher compared to other livestock Sri Lanka, there a threat transmit these organisms humans via food. The aim this study was determine E. prevalence stools and presence anti...

i ntroduction: calcium hydroxide (ch) is one of the most common intracanal medications. corticosteroids (cs) are used in endodontics because of their anti-inflammatory activity. this study aimed to evaluate the antimicrobial effect of ch+betamethasone and ch+saline against enterococcus faecalis ( e. faecalis ) using agar diffusion test and measuring the microbial zone of inhibition (zoi). metho...

Since Mexico is the second largest exporter of mangoes, its safety assurance is essential. Research in microbial ecology and knowledge of complex interactions among microbes must be better understood to achieve maximal control of pathogens. Therefore, we investigated the effect of UV-C treatments on bacterial diversity of the Ataulfo mangoes surface using PCR-DGGE analysis of variable region V3...

INTRODUCTION The urinary tract infections, after respiratory infections, are the most common in the community. The knowledge about the prevalence of microbial strains and their antibiotic susceptibility is crucial to establish an effective empirical therapy. The aim of this study was to determine the antibiotic susceptibility patterns of bacterial strains isolated from positive urine cultures p...

The melt-mixing method was used to obtain nanocomposites of ethylene vinyl acetate copolymer (EVA) with 1, 3 or 5wt% hydrophilic zinc oxide (ZnO) nanoparticles. contact angle, barrier and antimicrobial properties the obtained composites were investigated. characterized by better properties, as evidenced by, respectively, a smaller angle lower water vapor permeability absorption compared EVA, wh...

Background and Objective: This study was carried out to isolate lytic bacteriophages against Pseudomonas aeruginosa and analyze their biological characteristics and antibacterial effects on other clinical isolates of bacteria. Methods: Isolating two lytic bacteriophages against two strains of P. aeruginosa was carried out using the double-layer agar method. After investigating the antibacteria...

Background: Alkaloids are a group of nitrogen- containing natural compounds derived from a variety of sources including bacteria, fungi, marine organisms and plants. Materials and methods: Fruits, stem or leaves were collected from the Zagros highlands around Azna or Khoramabad city, dried and powdered before being extracted in a soxhalet apparatus. The extract was filtered and concentrated u...

results the chemical analysis of s. khuzestanica essential oil revealed the presence of carvacrol (94.1%) as its main component. the inhibition zone diameters of s. khuzestanica essential oil and carvacrol dose-dependently increased. the minimum inhibitory concentration (mic) values of s. khuzestanica essential oil and carvacrol were 0.14 ± 0.08 µl/ml and 0.09 ± 0.04 µl/ml, respectively. s. khu...

BACKGROUND Among the enteric pathogens, diarrheagenic Escherichia coli are important causes of diarrhea in children in both developing and industrialized countries. Some Lactobacillus species are commonly used as probiotics, with effects especially against acute diarrhea in childhood. OBJECTIVES The aim of this study was to explore antimicrobial activity of Lactobacillus strains isolated from...

background: antimicrobial peptides play a role as effectors substances in the immunity of vertebrate and inverte­brate hosts. in the current study, antimicrobial peptide was isolated from the haemolymph of the american cock­roach, periplaneta americana . methods: micrococcus luteus as gram-positive bacteria and escherichia coli as gram-negative bacteria were candi­date for injection. induction ...
