Introduction Accumulation of C. botulinum in soil occurs through excretion of bacterial spores from the intestines of humans, animals, birds and fish. In Georgia, during the winter season, the population consumes homemade vegetable preserves, which are made of locally produced (as well as imported) vegetables. Historical surveys confirmed that the presence of C. botulinum in the soil is widespr...

This study was carried out to determine the effects of Immunogen as a prebiotic on growth-related parameters and gut micro-flora in R. kutum fry. A basal diet was formulated using common feed ingredients supplemented with Immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  Fish were randomly distributed in 500 L fiberglass tanks (1×1×0.5 m). The experiment lasted for eight ...

Water harvesting is the collection of runoff for productivity purposes, instead of runoff being left to cause erosion. In arid and semi-arid drought-prone areas, micro-catchments are widely used as a water harvesting method to improve rangeland condition. The aim of present study was to investigate the effects of micro-catchment on ecological indices of rangeland health in Ghick-Sheikhha, Jirof...

Background: Tillage systems such as zero tillage and minimum or reduced leave more crop residues offer greater protection to soil erosion. Besides appropriate selection of practices, the improvement in average yield per hectare can be achieved by maintaining fertility through proper rate mode application fertilizers. Inorganic organic sources nutrients have potential reversing declining soil-he...

Soil contains almost twice as much carbon (C) as the atmosphere and 5-15% of soil C is stored in a form of particulate organic matter (POM). Particulate organic matter C is regarded as one of the most labile components of the soil C, such that can be easily lost under right environmental settings. Conceptually, micro-environmental conditions are understood to be responsible for protection of so...

INTRODUCTION The normal flora can be divided into two groups Resident flora and Transient. Some organisms are almost always present in a normal oral cavity and constitute constant/normal microbial flora. It is further divided into two types: indigenous & supplemental. Comprise of those species that are almost always present in high numbers (> 1%) in a particular site, such as the supra gingival...
