Nonhealing chronic wounds are all unique in origin and circumstance, and attempting to isolate a single etiology for the failure of a wound to heal is daunting. Wounds represent complex systems of multispecies fungal and bacterial biofilms. The survival strategies of interactive microbial communities have led to cooperative evolutionary strategies that culminate in biofilm formation. In microbi...

Antimicrobial activities of methanolic and petroleum ether extracts of Croccus sativus L. (saffron) stigmas, were tested against various bacterial strains (Proteus vulgaris, Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli) and fungi (Candida albicans, Aspergillus niger and Aspergillus fumigatus) by agar well diffusion method. Minimal inhibitory concentra...

Abstract Food is indispensable for humans as their growth and survival depend on it. But nowadays, crop getting spoiled due to fungi bacteria soil temperature are changes very rapidly according sudden climate changes. Due fungi-bacterial crop, the quality of food declining day by this really not good human health. The goal research paper advanced detection diseases in plants using modified deep...

Effect of nano composite films to prolong the shelf life of Iranian beluga caviar was investigated at different concentrations of silver nanoparticles. In this study 38 caviar packs each containing 5 g of caviar were divided into 6 treatments with 3 replicates. The concentrations of 1000, 2000, 3000, 4000, 5000 and 6000 ppm of nanoparticles as well as a nano free pack as control were used. The ...

Background: Bio aerosols include airborne micro-organisms such as bacteria, fungi, viruses, etc and their products. Exposure to a bio aerosol is linked with a broad spectrum of health problems, including infectious diseases, acute toxic effects, allergies, and cancer. The aim of this study was to evaluate the quality and quantity of bio aerosols found in the air of different wards in Valiasr Ho...

OBJECTIVES Acute meningitis and encephalitis (AME) are common diseases with the main pathogens being viruses and bacteria. As specific treatments are different, it is important to develop clinical prediction rules to distinguish aseptic from bacterial or fungal infection. In this study we evaluated the incidence rates, seasonal variety and the main etiologic agents of AME, and identified factor...

AIMS To assess the effects of dolomitic limestone applications on soil microbial communities' dynamics and bacterial and fungal biomass, relative abundance, and diversity in metal reclaimed regions. METHODS AND RESULTS The study was conducted in reclaimed mining sites and metal uncontaminated areas. The limestone applications were performed over 35 years ago. Total microbial biomass was deter...

background :   chitosan is unbranched polysaccharide composed of d-glucosamine and n-acetyl-d-glucosamine. chitosan, derived from shrimp shell, has broad antimicrobial properties against gram-negative, gram-positive bacteria and fungi.   methods :  chitosan was extracted from shrimp shell and studied for cell entrapment and anti-bacterial properties. the hydrogel chitosan was used as the beads ...
