Pathogens, Microbes and Bacteria--Oh My!

Yesterday, after I noticed Cooper licking a very public bench, I started to think about things like germs, viruses, bacteria, pathogens and infectious microbes. Imagine that. Though today parents are often armed with an arsenal of hand-wipes and hand sanitizer and are strict enforcers of the hand washing rule, it’s only been since the mid-nineteenth century that we had any idea at all how illness was spread. As I did some research for this blog, I was surprised to learn that all of the advances in modern medicine in the last several decades have had less of an effect on the spread of disease than changes in human behavior.  Hand washing wasn’t even a common practice until after 1847 when Hungarian doctor Ignaz Semmelweis noticed that many more new mothers were developing life-threatening infections and high fevers just after giving birth if his students took part in delivering their babies than if a midwife helped to deliver the baby. Why was this? Many of the medical students attended the births right after performing autopsies and educational cadaver dissections.  Instead of washing their hands between the two, they’d simply wipe their hands on their clothes as they walked to the delivery room. I think every single parent today would like to thank Dr. Semmelweis for this discovery. Aaaack! (Evolution and History of Personal Hygiene by Ingrid Koo, Ph.D)

Other important discoveries were made by Dr. John Snow who discovered that drinking water sources often played a major role in the spread of illness. Drinking water that was prone to contamination from animal or human waste coming from upstream or direct contamination from sewage (that was emptied from chamber pots right into the streets) were related to deadly cholera outbreaks. Thank you, Dr. Snow. Last, but not least, was Thomas Crapper of England, who played a major role in the development of the “flushing toilet” which took waste through a series of pipes, to a location far from the humans who had excreted the waste to begin with. Not only was the waste far enough away and contained so that it would not contaminate drinking water, it no longer needed to be disposed of by hand. Thank you, Tom Crapper! Unfortunately, despite being aware of these invisible dangers, parents can’t always prevent their curious offspring from putting disgusting things into their mouths—like Cooper sucking on the bench, or the time I caught Lauren licking the armrest on an airplane or crawling baby Kate tasting a piece of dried up dog poop in the backyard. We also need to thank Dr. Alexander Fleming for stumbling upon the antibiotic properties of penicillin during his study of bacteria and American Dr. Jonas Salk for coming up with world's first vaccine.  What is the grossest object you have caught your baby mouthing?

  • My baby will be born in a couple of weeks, and one thing I think about from time to time is how much stuff babies touch and put in their mouths! I am kind of a germ-phobe, so I’m worried how I’m going to be able to let go about this baby habit that I don’t think can really be avoided!!!

  • Man, germs… I tried so hard to control germs with my first child, now with 4 kids, they are always muddy.

  • Okay, your son licking the park bench grabbed my attention! I am SO very thankful for the flushing toilet! ;) Although we all know it’s best to avoid licking a dog turd or a park bench these things do happen occasionally with little ones (tee-hee). Regardless, it is important to teach kiddos to wash their hands… I’ve seen many preschool aged children that simply don’t have a habit of it (seriously I’m not kidding). But all of us have had an experience where we just need to laugh… like the time my daughter finger-painted her wall with the contents of her diaper (she is 10 now and we still tease her about it).

  • This is so funny. I am always telling my kids to stop licking things! Just today, my 8 yr old was licking our car. Yesterday, my almost 2 yr old was licking the air blower at a Walmart Family bathroom. I couldn’t move him away from the hand dryer fast enough. YUCK!!!!
