Micrasterias denticulata

Micrasterias is a Desmid - a group of green algae mostly found in neutral to acidic fresh waters and sphagnum bogs. Most are unicellular, though a few form chain-like colonies. Each cell is constructed of 2 semicells which are mirror images of each other. In Micrasterias the cells are flattened ... Read More

Listeria monocytogenes against brain macrophages.

Listeria monocytogenes has a particular tropism for the central nervous system. To gain knowledge about the immune response elicited by L. monocytogenes in the brain, we used a rat ex-vivo organotypic nervous system culture as a model for Listeria infection. Brain sections were maintained severa... Read More

A dangerous bridge for Serratia.

Serratia spp. are widely distributed in nature. Serratia marcescens is the most common Serratia sp. associated with human disease, followed by strains of the S. liquefaciens complex: S. liquefaciens, S. grimesii and S. proteamaculans. The clinical significance of these species is largely unknown... Read More
