Soil microflora of the rhizosphere of plants from several habitats in the botanical garden in Poznań

The abundance and activity of certain groups of soil microorganisms were estimated in the rhizosphere of 13 plants from four different habitats at several dates. An additional study was made of the rhizosphere microflora of Ledum palustre from a peat-bog. Numbers of proteolytic, nitrate assimilating, denitrifying, and cellulolytic bacteria were estimated. The intensity of ammonification, nitrification and Clostridium growth was estimated. The studies have revealed that the abundance and the activity of all the groups of bacteria studied depended on the habitat. Within one habitat, however, the influence of the plant was sometimes more pronounced than that of the habitat itself, particularly on the abundance of proteolytic bacteria (Fig. 1). The date of sampling had very little effect on the abundance of all the bacterial groups studied except the cellulolytic bacteria.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
