流行性感冒(流感)嗜血杆菌(Haemophilusin fluenzae,Hi)是常见的致病菌,仅对人类致病。1931年,Pittman将Hi分为带荚膜菌株及不带荚膜菌株(不定型) ,荚膜菌株据荚膜多糖的特异性抗原不同分为6个血清型(a～f) ,其中b型(Hib)毒力最大。Hib通过飞沫传播,是引起儿童侵袭性感染的重要
Influenza (flu) Haemophilusin fluenzae (Hi) is a common pathogen that causes disease only in humans. In 1931, Pittman divided Hi into capsular strains and non-capsular strains (unspecified). The capsular strains were divided into six serotypes (a ~ f) according to the specific antigen of capsular polysaccharide. Type b (Hib) is the most virulent. Hib through the droplets spread, is caused by invasive infection in children is important
