Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.
Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.
Fungal diseases can be challenging to diagnose due to their often nonspecific symptoms and the wide range of fungi that can cause infections. Accurate diagnosis is crucial for effective treatment. Here’s an overview of clinical, conventional, and molecular approaches for diagnosing fungal diseases. Different Approaches to Fungal Disease Diagnosis Fungal diseases can be difficult due […]
Plesiomonas shigelloides A facultative anaerobic gram-negative bacteria, Plesiomonas shigelloides is frequently found in watery settings such as rivers, lakes, and oceans. Additionally, it has been isolated from a variety of species, such as chicken, fish, shellfish, and reptiles. This bacterium is frequently found in freshwater, brackish water, and saltwater, among other settings. Animals also contain

Rickettsia is a genus of obligate intracellular bacteria that cause a variety of diseases in humans. Rickettsia diseases infections are usually spread by arthropod vectors such ticks, fleas, and lice. Here’s a detailed look at the etiology of the two main Rickettsia disease groups: Typhus fever and Spotted fever. Rickettsia diseases Rickettsia diseases are infections

What is Cell culture? In biology and medicine, cell culture is a potent technique that allows cells to be grown in a controlled environment apart from their native live organism. This makes it possible for researchers to study cells in a way that is not feasible inside a living body—that is, how they operate and
Ear infections are widespread and can affect several areas of the ear, most notably the external (otitis externa) and middle (otitis media). Here’s an in-depth look at these disorders, including their classifications, causative agents, clinical symptoms, and diagnostic procedures. Ear infection Ear infections are inflammations or infections that can affect any portion of the ear,

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
An eye infection is an inflammatory disorder caused by bacteria, viruses, fungus, or parasites that can produce redness, swelling, pain, discharge, and reduced vision, depending on the kind and degree of the infection. Eye Infections: Detailed Overview Types of Eye Infection 1. Conjunctivitis (pink eye) Causative agents Bacterial: Viral: Allergies: 2. Keratitis Types and Causative

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

Meningitis is an inflammation of the protective membranes surrounding the brain and spinal cord, known as the meninges. It may be categorized into two primary types: purulent (bacterial) and aseptic (viral or other non-bacterial causes). Here’s an in-depth look at both. Purulent Meningitis (Bacterial Meningitis) Bacterial infections induce purulent meningitis, which results in pus collection
