Swab results - November

If you joined us for the biomedical practical session at our November 19 Open day, you can now see your results!

The images are numbered, so you should be able to locate yours easily. All of the images have been labelled with the sample origin – so that you can compare your results with others.

What we found

You’ll notice that the swabs from skin (hands, ear, beard) all cultured very similar bacteria. There are some differences – but remember, these are from different people, living in different places – interesting that the human skin microbiota is similar for different people!

For an interesting take on how the microbes on the skin help us fight of disease – read this.

Really interesting plates to look at are plates 22 and 23 – hands, before and after hand wash, that claims to kill 99.99999% of bacteria.

One thing to notice is the nose swab plate – no. 13. Notice how different it is to the skin swabs – and also how homogenous it is – i.e. only one type of bacteria. Here is an interesting article on nose bacteria, if you are interested to read into it.

If you have any questions, please email David.Lee@bcu.ac.uk

And one final point to leave you with – the type of growth agar that we used will not be the correct environment for some bacteria to grow on – so the likelihood is that there will be many more bacteria on your swabs than we see!
