Acinetobacter spp. exists in human interstitial areas, armpits, toes, throats and various secretions of healthy people. In about 25% of normal people, they constitute a small part of human skin flora, and are also colonized in the digestive tract of infants and adults.It was separated as early as 1914.
Gram-negative Coccobacteria, which is usually arranged in pairs and can exist alone, sometimes forming filaments and chains. The cell size is 1.5~2.5um. Gram staining is not easy to fade. Mucinous strains have capsules, no spores and no flagella.
Patients with low immune function, that is, people with weakened immune system, chronic lung disease or diabetes, are vulnerable to infection. Acinetobacter has the potential to cause lung infection, wound and skin infection, urogenital infection, bacteremia and meningitis. Patients using respirators and patients using invasive devices (such as urinary tubes) have a higher risk of infection with Acinetobacter, and Acinetobacter usually breaks out in the intensive care unit (ICU).
