What is Theta Plasmid Replication ? Bacteria contain a particular kind of circular DNA molecule called theta plasmid. Because of the distinctive intermediate structure that forms throughout the process, its replication is named after the Greek letter theta (θ). Theta plasmid replication is a DNA replication technique present in certain circular plasmids, so called because […]
What is Francisella tularensis ? The highly contagious and sometimes lethal bacterium Francisella tularensis is the source of tularemia, a zoonotic illness that can afflict both people and animals. Given its high infectivity and potential for aerosol transmission, this bacterium is considered a Category A bioterrorism agent and requires a full study of its biology. Morphology Gram-negative coccobacillus: Under a microscope, F. tularensis appears as tiny, round-to-oval-shaped bacteria that frequently resemble cocci.Pleomorphic: It can change shape and size, which makes identification difficult.Non-motile: It is immobile since it does not have flagella.Facultative intracellular: F. tularensis may proliferate and persist in phagocytic cells, such as
Central Nervous System Infections Serious illnesses that can result in severe morbidity and mortality include infections of the central nervous system (CNS). These include infections of the meninges, which are the membranes that surround the brain and spinal cord, as well as the brain and spinal cord. Frequently, fungus, viruses, bacteria, or parasites are the

What is Dengue? A viral infection spread by mosquitoes, its fever is quickly becoming a serious worldwide health issue. There are four different dengue virus serotypes that cause it, and although symptoms can vary from mild to severe, in certain situations it can be fatal. The virus known as dengue is spread by the bite of an infected Aedes mosquito. These mosquitoes are distributed worldwide in tropical and subtropical climates, where they reproduce in stagnant water. Its fever is a viral ailment spread by
What is Chronic Obstructive Pulmonary Disease (COPD) ? A class of lung conditions known as chronic obstructive pulmonary disease (COPD) results in breathing difficulties and airflow obstruction. Because of its progressive nature, the illness worsens with time. Long-term exposure to irritants such as dust, air pollution, and cigarette smoke is the main cause of COPD.
What is Biodiversity? Biodiversity is the range of diverse forms of life that can be found in one place includes fungi, plants, animals, and even microbes like bacteria that make up our natural world. Together, these various species and organisms form ecosystems that support life and preserve equilibrium, much like a complex web. It speaks

Spore staining Technique Spore staining Technique is one method for observing bacterial endospores, which are extremely resilient structures produced by certain bacteria in hostile environments, is spore staining. The thick protective shell of these spores makes them difficult to stain using standard dyes. By using a differential staining technique that contrasts the spore and vegetative

What is Bronchitis? An inflammation of the bronchi, the airways that transport air to and from the lungs, is known as bronchitis. In addition to irritants like dust, smog, and cigarette smoke, it may result from a bacterial or viral infection. Breathlessness, pressure in the chest, coughing, and wheezing are all signs of bronchitis. The
