Haemophilus influenzae Bacteria Attaching to a Surface (image) Oak Crest Institute of Science Share Print E-Mail Caption The bacteria called non-typeable Haemophilus influenzae are a common cause of infection in the upper respiratory tract. By attaching to surfaces in the body the bacteria form a biofilm. Wu et al. have reported that when the bacteria encounter non-lethal amounts of specific antibiotics they are stimulated to form a bioiflm, a structure that causes chronic infection and which can be highly resistant to antibiotics.
