The biology song

Hark! The Streptococcus Brings(Melody: "Hark! The Herald = Angels Sing")Hark! the Streptococcus bringsStrep sore throat to all who sing,Chloraseptic doesn't cure itOther people's sneezing lures it.If the strep bug has a virusScarlet fever then arises,Cross reaction with the heartCauses it to come apart,Hark! the Streptococcus totes,Toxin and fire to all it smotes.Pneumonia makes you cough and wheeze,Mucus fills the lungs with sleazeA viscous greenish oozing cloak,That causes you to gasp and chokeWithout water you can drownIf you breathe the strep germ downHark! The Streptococcus breedsThe misery of a bad diseaseOf fecal strep in food beware,Methane gas befouls the air,Speedily you drop your pantsAs if they held live fire antsOn the toilet you are dyingBent in pain, guts liquefyingHail! the Streptococcus meansGlory to those who would be lean
