Gram-negative bacteria are a diverse group of microorganisms known for their unique cell structure, which plays a key role in how they interact with the environment and cause infections. Unlike Gram-positive bacteria, Gram-negative bacteria have a thin peptidoglycan layer sandwiched between two membranes. The outer membrane contains lipopolysaccharides (LPS), which can trigger strong immune responses … Read more
Ever wondered how your cells turn the food you eat into usable energy? Let’s break down the Krebs cycle—a cornerstone of cellular respiration—and answer the questions you’ve been searching for. Also known as the citric acid cycle, this process is a series of chemical reactions that extract energy from nutrients. But where does this critical … Read more
Gram-positive bacteria are a group of bacteria classified based on how they react to a lab test called the Gram stain. When stained, these bacteria hold onto a purple dye because of their thick, mesh-like cell wall made of peptidoglycan. This sturdy layer acts like a protective shield, unlike Gram-negative bacteria, which have thinner walls … Read more
Tomato Spotted Wilt Virus, often called TSWV for short, is one of those frustrating problems that can really throw a wrench into your gardening plans or hit farmers hard. It’s not just a tomato issue either – this nasty virus has a surprisingly broad appetite, targeting everything from peppers and lettuce to popular flowers like … Read more
Multiphoton microscopy is a cutting-edge imaging technique widely used in biology and medicine to study living tissues with minimal harm. Instead of relying on single high-energy photons like conventional microscopes, this method harnesses multiple low-energy photons that act together to produce a fluorescent signal. The trick lies in timing—when these photons strike a molecule simultaneously, … Read more
The normal flora, or microbiota, in the mouth and gut refers to the community of tiny organisms—like bacteria, fungi, and viruses—that naturally live in these areas without causing harm. In the mouth, hundreds of species thrive, especially in warm, moist spots like the tongue, teeth, and gums. Common bacteria include Streptococcus, which helps break down food … Read more
typical flora of skin, hair, and nails is the stable community of microorganisms—mostly bacteria and fungus—that live on the outside surfaces of the human body without causing damage under typical circumstances. These communities, sometimes referred to as the skin microbiome, occupy ecological niches, fight against infections, and generate molecules that stop microbial invasion, therefore safeguarding … Read more
What is Eye and Ear Microbiota (Microbiome) or Normal Flora of Eye & Ear? Normal Flora of the Ear Microorganism Type Category Staphylococcus spp. Gram-positive Bacteria Alloiococcus otitis Gram-positive Bacteria Corynebacterium spp. Gram-positive Bacteria Microbacterium spp. Gram-positive Bacteria Bacillus spp. Gram-positive Bacteria Arthrobacter spp. Gram-positive Bacteria Turicella otitidis Gram-positive Bacteria Micrococcus spp. Gram-positive Bacteria Moraxella … Read more
The human body is home to trillions of tiny organisms, like bacteria, fungi, and viruses, that live on the skin, in the mouth, gut, and other areas. This community of microbes is called the human microbiome. Most of these organisms aren’t harmful—in fact, many are essential for health. They help digest food, produce vitamins, and even … Read more
What is Rhizosphere? The rhizosphere is the small area of soil around plant roots that is directly affected by root secretions and the microbes that live there. Usually goes about one millimeter from the root surface and includes soil that sticks to the roots and can be easily shook off. Root exudates and rhizodeposition: Roots … Read more
