The Rumen Gut Microbe For Life

Introduction Ruminants diet is rich in fiber (consists of polymers e.g. cellulose) and low in proteins. Almost all animals as well as mammals lack the enzymes for metabolizing cellulose. Only microorganisms possess such enzymes which aid in fermenting cellulose and other polysaccharides consumed by the ruminants. The microorganisms are in a symbiotic relationship with the …

Review on Cyanobacteria

Cyanobacteria are photosynthetic bacteria that share some properties with algae and are found naturally in lakes, streams, ponds, and other surface waters. Cyanobacteria can rapidly multiply in surface water and cause “blooms.” Several types of cyanobacteria, for example Anabaena sp have gas-filled cavities that allow them to float to the surface or to different levels …

Tetanus: what is it?

What is Tetanus? Tetanus is a serious bacterial infection that affects the nervous system and causes muscles throughout the body to tighten. It’s also called lockjaw because the infection often causes muscle contractions in the jaw and neck. However, it can eventually spread to other parts of the body. Tetanus infection can be life threatening …

What Is Donovanosis, A So-Called ‘Flesh Eating’ Sexually Transmitted Infection?

There are some bacteria in the environment that are so pervasive and detrimental as the disease process caused by them made it looks like we are getting eaten by an unseen entity typically known as the flesh-eating microbial agents. Among all of the sexually transmitted diseases, donovanosis can be considered as one of the flesh-eating …

Extremophiles features and role

Extremophiles are organisms that live in conditions which humans consider “extreme.” “Extreme” environments include but are not limited to extreme pressure, extreme cold, intense heat, highly acidic environments, and highly saline environments. These conditions were once believed to not have the ability to sustain life. There are three domains of life: Eukarya, Bacteria, and Archaea. …

Evaluation of miR148 and miR-204 Expression in Patients Infected with Helicobacter Pylori

Helicobacter pylori is a gram-negative bacterial mycobacterial microarrophylic that the pathogenic bacteria reside selectively in the epithelium of the stomach. This bacterium is responsible for diseases such as gastric cancer, lymphoma, gastritis and gastrointestinal ulcers. H.Pylori colonization produces chronic superficial gastritis and basically all people with H. pylori colonized have gastric inflammation, but less than …

What are Biofilms?

Biofilms are structured communities of bacteria that play a role in antibiotic resistant infections on catheters, which are tubes inserted through a narrow opening into a body cavity or for removing fluids, and other medical prosthetic devices. Bacteria can exist in the body as a single cell or as biofilms. Despite attempts at reducing infections …

Identification And Localization Of The S-Layer Proteins Of Two Acidithiobacillus 

Acidithiobacillus strains SP5/1 and HV2/2 are rod-shaped, Gram-negative, γ-proteobacterium, aerobically pyrite-oxidizing and Acidophilic bacteria that thrives optimally at 30°C and 45°C respectively (Klingl, Moissl-Eichinger et al. 2011). S-layer molecular structure similarity in symmetry in the closely related species can be used as a taxonomic characteristic that distinguishes phylogenetic position of the organism (Baumeister and Lembcke …

Phagocytosis And The Respiratory Burst

Introduction Phagocytes play a pivotal role in innate immunity and are the initial cells involved in an immune response. They are a family of cells including, monocytes, dendritic cells, neutrophils and macrophages. Phagocytes are able to recognise Pathogen Associated Molecular Patterns (PAMPS) associated with ‘non-self’ cells using Pattern Recognition Receptors (PRR’s) on their cell surface. …

Treatment Of Bacterial Biofilm Infections

Bacterial biofilms now represent the dominant bacterial growth lifestyle in different habitats including natural and clinical environments. Bacterial cells switch between the free-living planktonic mode and the biofilm growth mode, through multiple mechanisms that include adhesion to a substratum, increasing their aggregation into microcolonies and mature biofilms via matrix formation through secretion of extracellular polymeric …

Structure Of Pneumococcal Bacteria

Early observations by application of specific strains revealed that virulent pneumococci were surrounded by a structure now recognized as the capsule. The capsule played a central role in the discovery of the ‘transforming principle’ since it was using this genetic trait and this microorganism where DNA and genetic information were first linked. (R. Lopez et …
