How a proper application of Koch’s postulates would have prevented the misnaming of Haemophilus influenzae , which was named so because researchers isolated the organism from flu patients. Introduction : Haemophilus influenzae is an extremely small Gram negative parasitic bacterium, belonging to the Pasteurellaceae family, which requires heme in blood and NAD+ to thrive. It has virulence factors like polysaccharide capsule and K antigens that help it to cause infection. Even though it’s named so , H. influenzae do not cause flu, but it causes some fatal conditions in children like severe epiglottis, meningitis, and arthritis. Thus the name given to this bacterium is a misnomer, after it was named according to Koch’s postulates.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
