Bacteria are single-celled organisms that are pretty much everywhere: in the ground, in the ocean, on your hands and in your gut. While some are harmful, most are not — and some are even beneficial to human health. In many cases, humans live in symbiosis with bacteria, maintaining a mu...
the US Food and Drug Administration only allows doctors to use fecal transplants experimentally for battling one of the toughest gut infections— antibiotic-resistantClostridiodesdifficile. This infectious bacterium forms spores in...
Fragmentation is used in the cloning and propagation of many plant species. Spore production is another method of reproduction that people may be familiar with, with some species producing spores that can mature into adult organisms. Another method, commonly used by bacteria, is binary fission. In...
Are spores virulence factors? What is the virulence factor of Neisseria meningitidis? What is the virulence factor on coagulase negative staph? Why do pathogens produce virulence factors? What type of virulence factor causes diarrhea? What type of virulence factor is hyaluronidase?
Oospores are thick-walled spores formed by the fusion of two gametes in fungi, while zoospores are motile, flagellated spores used for asexual reproduction in algae and fungi.
Bacteria are very small i.e. microscopic organisms (microoorganisms), classified under Kingdom Monera, and are both unicellular and prokaryotic. While some bacteria are considered to be beneficial, for instance: in that comprise intestinal flora e.g. Lactobacillus acidophilus, there are those that...
Spores of many species of the orders Bacillales and Clostridiales can be vectors for food spoilage, human diseases and intoxications, and biological warfare. Many agents are used for spore killing, including moist heat in an autoclave, dry heat at elevated temperatures, UV radiation at 254 and...
There are two forms of intestinalB. cereus: Enterotoxins (diarrheal syndrome).This type is the most common in the United States and Europe. With this version, your body makes the toxin in your small intestine after you've eaten food with the bacteria or spores (the cells they make). Food...
Bacteria are evolved to adapt and survive in any kind of ecological niches; from normal toextreme environments. Hence, they are ubiquitous. They are found in every possible habitat on the Earth; soil, air, and water. They are associated with all the biotic and abiotic components of the Earth...
The name “Actinomycetes” was derived from the Greek words “atkis” (a ray) and “mykes”(fungus). This suggests their structural similarity with fungi, but they are biochemically more close to bacteria and hence are included in the domain of Bacteria. They are connecting links between “...
