I lcapitulumned in the A & P course that enlace heel rebel (or capitulum resurrect) is a waxy secretion by ceruminous gland (= modified sebaceous gland), mixed with sloughed epithelial cells, which inhibits the fruit of certain bacteria due to its acidic pH. It as well as protects the pelt of the external auditory canal by providing a seal layer, so, it?s something beneficial to us. Sure enough, there see to be a number of denominations written to support this - germicidal performance of earwax, Chai & Chai (ref 1), Bactericidal activity of wet cerumen, tilt & Fulghun (ref 2), etc. (though this concept is refuted by a after try out! (ref 3))On the other hand, I could find but very few members that discuss the role that ear wax plays in unhealthiness transmittal or as a admission of live for pathogens. I started with an article by Kemp & Bankaitis (ref 4), in which it is stated that cerumen is not considered an infectious agent until it becomes pollute with fa rm animal or mucus, and it can even be placed in the fixity trash unless significant amount of blood or mucose is present. So, it appears the danger is not in cerumen itself but in blood/mucous contaminant. CDC lists Hepatitis B, Hepatitis C, HIV and viral Hemorrhagic Fever(VHF) as infectious diseases by bloodborne pathogens (ref 5). On the subject field of cerumen itself transmission bloodborne viruses, I could find only devil articles, both by the same group of researchers, Beyindir, Kalcioglu et al. First article is on the subject field of possible transmission of Hepatitis B (ref 6), in which the authors conclude that cerumen can be a potential address of transmission and further investigation for horizontal, nosocomial, and occupational transmission is necessary. The second article is on Hepatitis C, and it concludes that cerumen has no risk, even in patients with towering HCV RNA serum levels. I could not find every articles to confirm/deny cerumen as a source of tran smission for HIV or VHF.
I think our textual matter book lists ear wax as a portal of exit for pathogens, because of more(prenominal) than minimal potential risk of taint by blood, during handling of otitis, removal of impacted ear wax etc. performed by otolaryngologists/audiologists on a regular basis.
