Microbial mats, sheets of microorganisms held together by foam, dominated the planet before multicellular organisms evolved. Fossil evidence dates back 3.5 billion years, and the mats were initially chemoautotrophs before evolving photosynthesis. The first multicellular organisms may have lived attached to the mats, and the Cambrian Period marked the end of the mats’ dominance. They […]
Microbial insecticides target specific insects with bacteria, viruses, amoebas, or fungi, making them safe for non-target species. They are vulnerable to the elements and may require multiple sprays for different types of infestations. Some scientists express concern about their safety and potential for resistance, but others see them as a better alternative to traditional poisons. […]
Microbial genomes are complete sequences of genetic code from microorganisms, which can vary in size and complexity. Researchers can learn about evolutionary history and specific functions by sequencing the genome. Bacteria can carry plasmids, which can complicate analysis. Governments and labs worldwide study microbial genomes for scientific uses, such as environmental cleanup. A microbial genome […]
Microbial pathogenesis is the process by which microorganisms cause disease. There are four types of pathogenesis: inflammation, malignancy, tissue breakdown, and infection. Infections are the most common form and occur in three phases: initial infection, reproduction, and continuation. The microorganism’s goal is to replicate and spread before the body’s defenses destroy it. Transmission occurs through […]
Microbial forensics identifies microbial agents, their origins and potential effects, presenting findings as legal and scientific evidence. It’s crucial for prosecuting biocrime and medical malpractice cases and requires a multidisciplinary approach. The process involves sample collection, agent identification, risk analysis, and validation. Basic entry-level qualifications include a degree in biology or microbiology, and a master’s […]
