Chronic inhalation exposure to agricultural dust promotes the development of chronic respiratory diseases among poultry workers. Poultry dust is composed of dander, chicken feed, litter bedding and microbes. However, the microbial composition and abundance has not been fully elucidated. Genomic DNA was extracted from settled dust and personal inhalable dust collected while performing litter sam...
Haloalkaliphiles are polyextremophiles adapted to grow at high salt concentrations and alkaline pH values. In this work, we isolated 122 haloalkaliphilic bacteria upon enrichments of 23 samples from 5 distinct saline systems of southern Tunisia, growing optimally in media with 10% salt and at pH 10. The collection was classified into 44 groups based on the amplification of the 16S-23S rRNA inte...
The aim of the present study was to obtain insights into the relationship between the chemical (salt content and pH) and physico-mechanical (humidity and compressive strength) properties of mineral-based materials from historic buildings with salt efflorescence and the growth and biodiversity of halophilic microorganisms. Samples were mainly characterized by pH 6.5-8.5 and a moisture content of...
مقدمه: امروزه استفاده بیش از حد از تلوریت، محیط را متحمل اثرات سمی ناشی از این اکسیآنیون کرده است. از این رو تیمار زیستی مناطق آلوده، به عنوان روشی ارزان و سازگار با محیط زیست، مطرح است. اگرچه اثرات سمی تلوریت برای بیشتر میکروارگانیسمها گزارش شده ولی گونههای مختلفی از باکتریها، از جمله باکتری نمک دوست مورد استفاده در این پروژه میتواند بر سمیت آن با احیای این اکسیآنیون به شکل عنصریش غل...
Streptococcus agalactiae, or Group B Streptococcus (GBS), is a major pathogen causing neonatal sepsis and meningitis, bovine mastitis, and fish meningoencephalitis. CC23, including its namesake ST23, is not only the predominant GBS strain derived from human and cattle, but also can infect a variety of homeothermic and poikilothermic species. However, it has never been characterized in fish. Thi...
