Introduction
Corynebacteria are a common type of Gram-positive bacteria, primarily characterized by their rod-shaped or short bacillus morphology. Maintaining skin cleanliness is particularly important; take regular baths and use gentle cleansers to avoid damaging the skin barrier. Respiratory protection should not be overlooked—wear masks according to the environment when outdoors to reduce the risk of droplet transmission.
Corynebacteria are a common type of Gram-positive bacteria, primarily characterized by their rod-shaped or short bacillary morphology. A detailed analysis is as follows:
Corynebacteria are a group of Gram-positive bacilli. In their cellular structure, the cell wall contains peptidoglycan and teichoic acid but lacks lipopolysaccharide, staining purple in Gram staining. Some species are part of the normal human flora, colonizing areas such as the skin and respiratory tract. Under certain conditions—such as microbial imbalance or decreased host immunity—they may cause infections. Their morphological features and physiological characteristics together form the core basis for classification and identification.
Maintaining skin cleanliness is particularly important; regular bathing with mild cleansers helps prevent damage to the skin barrier. Respiratory protection should not be overlooked—wearing masks according to environmental conditions when outdoors can reduce the risk of droplet transmission. Nutritionally, a balanced diet rich in vitamins strengthens the body's immune system. Living environments should be regularly ventilated and disinfected to ensure air circulation and reduce the likelihood of bacterial growth.
