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 (TSWV), caused by the pathogen Tomato spotted wilt orthotospovirus, is a devastating threat to global agriculture, particularly affecting crops like tomatoes, peppers, and potatoes. Recognized by its scientific name in research, this virus spreads rapidly through thrips, its primary insect vector, making tomato spotted wilt virus transmission a major concern for farmers. Early identification of tomato spotted wilt virus … 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
The rhizosphere is the narrow zone of soil that surrounds plant roots, acting as a bustling hub of biological and chemical activity. Imagine it as a dynamic marketplace where roots, microbes, and soil particles constantly interact. Plants release a mix of sugars, acids, and other organic compounds through their roots—a process often called “root exudation.” … Read more
What is Dutch elm disease (DED)? Dutch elm disease, often called DED, is a nasty problem for elm trees. It’s caused by a type of fungus that gets carried around by tiny beetles. When these beetles munch on healthy trees, they leave behind fungal spores that grow inside the tree’s veins—the parts that move water … Read more
What is Fusarium Wilt? Fusarium wilt is a plant disease that’s been giving gardeners and farmers headaches for ages. It’s caused by a sneaky soil-dwelling fungus called Fusarium oxysporum, which basically invades a plant’s roots and starts clogging up its internal plumbing. Imagine the plant’s vascular system—the tiny tubes that move water and nutrients—getting blocked by … Read more
