It is possible that if hemophilus influenzae is the disease causing bacteria, endotoxins were released because it is gram negative. The lipid a component of lps of the gram cell wall are found in the pus. When the bacteria evades the host cell, it can cause the immune system to overreact causing an inflammatory response. Fevers are associated because endotoxins produce the same effects (chills, aches, fevers etc) [lecture] Wanda believes that amoxicillin will always be able to cure fredrica of her ear infections.
