铜绿假单胞菌是一种条件致病菌,其适应性、普遍性和致病性密切相关。铜绿假单胞菌的细胞相关和胞外产物都有助于其毒力。表面结构,包括皮利和多糖囊或糖萼,似乎介导铜绿假单胞菌与其预期宿主的初始附着,从而允许定殖。胞外酶如碱性蛋白酶、弹性蛋白酶、磷脂酶C和外毒素A降解感染的组织并促进细菌入侵。当发生传播时,会导致全身性疾病,通常会造成致命的后果。虽然铜绿假单胞菌的胞外酶在局部疾病过程中起重要作用,但外毒素A和内毒素是全身性疾病的主要原因。目前已知的最具保护性的抗体针对铜绿假单胞菌脂多糖的无毒部分,其本身不具有已知的毒力功能。然而,有初步证据表明,这些调理素抗体的保护活性可以通过针对内毒素和外毒素A的脂质A部分的毒素中和抗体来增强。
Pseudomonas aeruginosa is an opportunistic pathogen whose adaptability, ubiquitousness, and pathogenicity are closely related. Both cell-associated and extracellular products of P. aeruginosa contribute to its virulence. Surface structures, including pili and the polysaccharide capsule or glycocalyx, appear to mediate the initial attachment of P. aeruginosa to its prospective host, thus permitting colonization. Extracellular enzymes such as alkaline protease, elastase, phospholipase C, and exotoxin A degrade infected tissues and promote bacterial invasion. When dissemination occurs, systemic disease results, often with fatal consequences. Although extracellular enzymes of P. aeruginosa figure prominently in local disease processes, exotoxin A and endotoxin are primarily responsible for systemic disease. The most protective antibodies presently known are directed toward the nontoxic portions of P. aeruginosa lipopolysaccharides that serve no known virulence function per se. However, there is preliminary evidence that the protective activity of these opsonic antibodies may be augmented by toxin-neutralizing antibodies directed toward the lipid A moiety of endotoxin and exotoxin A.
