|Description:||Under a magnification of 1000X, this photomicrograph reveals the following findings in this sample of a transtracheal aspirate. The report read that there are Gram-negative rods, and Gram-negative cocci, which were determined to be Haemophilus influenzae, and non-meningococcal Neisseria sp. organisms respectively. See PHIL 15536, for another photomicrographic view of this specimen.|
Haemophilus influenzae, including Hib, is a bacterium that can cause a severe infection, occurring mostly in infants and children younger than five years of age. It can cause lifelong disability and be deadly. In spite of its name, H. influenzae bacteria do not cause influenza, otherwise known as the "flu".
Non-meningococcal Neisseria sp. organisms are normally found in the human respiratory tract, and are felt to be low on the scale of pathogenicity, however, in some cases, these commensal organisms have been found as the cause of disease including endocarditis.
