In this article we will discuss about the mechanisms of innate immunity in bacterial infection. Bacteria-Host Interactions at Body Surfaces: The totality of mechanisms constitutes our immunity to infection. Infection is caused rarely due to multifunctional systems of innate immunity. It is divided into those systems which (a) act at body surfaces (epithelium or submucosa), and (b) those which are [...]
In this article we will discuss about the effect of mycorrhizal fungi on their hosts. Similar to rhizosphere, mycorrhizosphere (the close vicinity of ectomycorrhizae) shows increased microbial community leading to mycorhizosphere effect. The photosynthates flow into soil through roots and mycorrhizae support a diverse community of soil microorganisms, many of which influence plant growth. The mycorrhizosphere microorganisms may be facultative [...]
This article provides a brief overview of key points in cellular biology underlying prokaryotic-eukaryotic interactions. 1. Bacterial Ultra-Structure: Bacteria are the smallest organisms living independently. Their size, shape and dimension vary. 2. Pathogenicity Islands: Bacterial pathogenicity is governed by inter-species transfer of virulence factors contributed by plasmid and transposons. Pathogenicity is becoming apparent also. The interspersed elements (within the genomes [...]
