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 …
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 …

Introduction Bacteria is all around us despite that we are oblivious to its existence. It is common knowledge that bacteria exists, but it is easy for people to dismiss this fact as we cannot actually see the build-up of growth in surrounding areas. The colonies of bacteria that propagate vary depending on the location, and …
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 …

Bacteria are microscopic single celled organisms that thrive in diverse environments. They can live within soil, in the ocean and inside the human gut. The three basic bacterial shapes are spherical, bacillus and spiral. (Aryal.S,2015) Tuberculosis (TB) is a bacterial infection that spreads through inhaling tiny droplets from the coughs or sneezes of an infected …
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.

Everyone knows that the antibiotic resistance is elevating to dangerously high levels in all parts of the world. The antibiotics that were used to save millions of lives are no longer effective towards the swift emergence of resistant …
Recent studies have demonstrated phage therapy successfully treated infections caused by resistant bacteria species. Phages were effective for the elimination of food poisoning pathogenic bacteria such as Campylobacter jejuni ,Listeria monocytogenes, and Salmonella spp. In 2006, FDA approved the use of combination of six phages to be sprayed on ready-to-eat meat and poultry to eradicate …
Everything humans touch is brimming with billions of microbes. People eat at their desks, they put their bags on dining room tables, and they turn doorknobs that hundreds of other hands have touched. These things are done without a second thought, despite the fact that 80% of infections are spread via human hands. (1) The …
The cell wall of Gram-positive bacteria is a major cellular component responsible for maintaining the structural stability, providing a barrier to osmotic pressures, facilitating interactions with the surrounding environment and essential for its survival.
