The temperature and pH of saliva makes it conducive for bacteria to survive in the oral cavity. Bacteria in the oral cavity include Streptococcus mutans, Porphyromonas gingivalis, and Staphylococcus. [15] S. mutans is the main component of the oral microbiota. [15] A healthy oral microbiome decreases oral infections and promotes a healthy gut ...
Most bacteria in the human body are actually good for us and help with carrying out necessary life processes. Gut bacteria in humans often aid in the breakdown of foods and synthesize important vitamins that could not be processed by humans alone. [16] Therefore, humans must be careful when taking antibiotics when they are sick. Antibiotics do ...
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...

Bacteria: Escherichia coli (E. coli), common Gram-negative gut bacterium widely used in molecular genetics. Main lab strain is 'K-12'. Bacillus subtilis, endospore forming Gram-positive bacterium. Main lab strain is '168'. Caulobacter crescentus, bacterium that divides into two distinct cells used to study cellular differentiation.
Humans are home to 10 13 to 10 14 bacteria, roughly equivalent to the number of human cells, [2] and while these bacteria can be pathogenic to their host most of them are mutually beneficial to both the host and bacteria. The human immune system consists of two main types of immunity: innate and adaptive.
Because this phylum are able to form a symbiotic relationship with plant roots, incorporating Pseudomonadota into agricultural practices aligns with principles of sustainable farming. [57] [50] These bacteria contribute to soil health and fertility, promote natural pest management, and enhance the resilience of crops to environmental stressors ...
Bacteroides species also benefit their host by excluding potential pathogens from colonizing the gut.Some species (B. fragilis, for example) are opportunistic human pathogens, causing infections of the peritoneal cavity, gastrointestinal surgery, and appendicitis via abscess formation, inhibiting phagocytosis, and inactivating beta-lactam antibiotics.
