Bugs And More Bugs
Parvo is a single dude, 19 years old, and a perv. He likes to get naked, and travel the globe for children to stalk. He likes to breathe on them and put lacey things on them. After the fifth incident, one of the kids’ mothers finds out, slaps Parvo on the cheek. Parvo gets mad and kills the babies.
In other words, B19 is a naked single-stranded DNA (“Dude”) virus belonging to the Parvoviridae family. It infects mainly children and causes a slapped-cheek rash on the face and lacy, maculopapular rash on the trunk and limbs of the body. It infects by binding to globoside (blood group P antigen) on erythroid precursors. It is spread through respiratory droplets (“breathing”). This disease is called Fifth Disease (Erythema Infectiosum). If mothers get infected, the virus can pass across the placenta, infecting and killing the fetus (hydrops fetalis). To diagnose, find IgM and IgG in the serology.
This and hundreds of more “bugs” are what we will be covering this semester in Medical Microbiology. For each bug, we will learn the species, family, infectious agent, reservoir, transmission, risk factors, virulence factors, clinical diseases they each cause, method of diagnosis, treatment, and prevention. In other words, it’s a lot of stuff to learn. How am I supposed to handle all this?
A good way to start is by making stories, and any med student would have a few good ones they use.
In my life, I’ve always loved doing things that would satisfy my drive to create: composing music, designing buildings, writing, drawing… In a way, I have found this opportunity in med micro. While it is one of the most intense classes I have taken so far in terms of rote memorization, it is a fun class because I can make up creative stories to try to let me remember all the details about the organisms and diseases. By the end of the semester, I’ll have lots of stories to tell you, and perhaps even more on Parvo later!
