BACKGROUND:The bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. OBJECTIVES:The aim of this research was to investigate the bacterialcontamination status, with emphasis on Escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated Escherichia coli. METHODS:Ato...

BACKGROUND Replacement of chloride ions in cyanuric chloride give several variants of 1,3,5-triazine derivatives which were investigated as biologically active small molecules. These compounds exhibit antimalarial, antimicrobial, anti-cancer and anti-viral activities, among other beneficial properties. On the other hand, treatment of bacterial infections remains a challenging therapeutic proble...

novel analogues of n-piperazinyl fluoroquinolones were prepared and evaluated against a panel of gram-positive and gram-negative bacteria, to study the effect of introducing bulky anthracene and phenanthrene moieties on the antibacterial effects of norfloxacin, ciprofloxacin and gatifloxacin. although most of the novel synthesized compounds had lower antibacterial effects, some derivatives show...

Background: Natural antioxidants with plant origin are incorporated to foods in the forms of essential oils or extracts. They can retard lipid oxidation and control spoilage bacteria in foodstuffs (e.g. meat products). Objective: This work was aimed to evaluate the effect of nitrite partial replacement with Mentha piperita essential oil (MPEO) on oxidative, microbial and sensory properties of...

The pulmonary collectins, surfactant proteins A (SP-A) and D (SP-D), have been reported to bind lipopolysaccharide (LPS), opsonize microorganisms, and enhance the clearance of lung pathogens. In this study, we examined the effect of SP-A and SP-D on the growth and viability of Gram-negative bacteria. The pulmonary clearance of Escherichia coli K12 was reduced in SP-A-null mice and was increased...

Antimicrobial activity of different culture extract of Oudemansiella sp grown on liquid medium (MYGP) were tested. Different fungi (C. albicans, C. lipolytica, Saccharomyces cervisiea, Cladosporium herbarum, and Aspergillus niger) and bacteria (Microccocus luteus, E. coli, Staphylococcus aureus, and Staphylococcus epidermidis) were used as test organisms. Various antimicrobial assay metho...

Objectives Periodontal diseases are one of the common oral diseases and microbial oral flora is one major factor responsible for it. Elimination of periodontal pathogens is particularly important in managing the periodontal state. This study aimed to assess the antibacterial effects of Nanosil, chlorhexidine (CHX) and probiotic mouthwashes on periodontal pathogens. Methods In this in-vitro stu...

Hydrogels described herein were developed as anti-microbial coating materials. Three different hydrogels, p(HEMA), p(85%HEMA-co-15% MMA), and p(85% HEMA-co-15% MAA) loaded with two cationic surfactants, BAK, DDAB, respectively. DDAB owned better effectivity than BAK in killing S. aureus E. coli. Compared to unmodified(HEMA), all drug-loaded samples exhibited significant anti-adherence ability a...
