| Description | Tyzzerella nexilis is a gram-positive, rod-shaped bacterium that thrives in a mesophilic temperature range, typically between 20-40°C. As a chemoheterotroph, it metabolizes organic compounds as its energy source, obtaining energy through aerobic respiration. This means that T. nexilis requires oxygen to generate energy, classifying it as an obligate aerobe. T. nexilis can be found colonizing the mucous membranes of the respiratory, gastrointestinal, and genitourinary tracts in humans and animals. It has also been isolated from soil and water samples. Its presence on the body is often asymptomatic, but can lead to opportunistic infections in individuals with compromised immune systems. In terms of body sites, T. nexilis has been detected on the lips, tongue, palate, tonsils, and larynx, as well as in the nasal passages, bronchi, and lungs. It can also inhabit the gastrointestinal tract, including the stomach, small intestine, and colon. In addition, it has been found on the skin, particularly in areas with occluded pores, such as the scalp and face. Tyzzerella nexilis is a versatile microbe that can adapt to various environments, which aids in its widespread distribution. Its ability to thrive in different body sites and environments makes it a resilient and successful pathogen. Despite its potential to cause disease, T. nexilis plays an important role in the ecosystem, helping to break down organic matter and recycle nutrients. One notable aspect of T. nexilis is its ability to form biofilms on surfaces, which allows it to adhere to surfaces and withstand antibiotic treatment. Its biofilm-forming capabilities also enable it to persist in the environment, making it challenging to eliminate. |
