Working with the 3 S's in Mind:
Science, Spin Filters, and Starbucks
This will be my last post as part of MO BIO Laboratories. I’m moving back home to be closer to my family in San Francisco. (Well, I’ve actually been home for close to two months already because this post is at the end of my extremely long queue). It’s been fun discovering, learning, and reblogging all the cool stuff happening in the life sciences. And it’s be a pleasure working for such an amazing company. I hope all my followers have enjoyed my posts over the course of JeremyMOBIO’s short existence. Keep blogging about science and tumblr on!
Shigella bacteria. Scanning electron micrograph (SEM) of Shigella sp. Bacteria (red) on the surface of a cell. Shigella sp. are Gram-negative rod-shaped bacteria (bacilli) and are the causative agent of human shigellosis. They infect the large intestine and cause dysentery, which can vary in severity from a mild attack of diarrhoea to an acute infection.

A fairy ring is a naturally occurring ring of mushrooms. They are also known as pixie’s rings, faerie circles, or elf circles. The English believed that fairy rings were where fairies came to dance and celebrate, the mushrooms of the rings were used as stools for the fairies to recuperate during the evenings festivities.

It’s been a big week for our microbiomes.
The first phase of an ambitious study to characterise all the bacteria, fungi, and other microbes that reside in our bodies has been completed, with the results published in a series of articles in Nature, PLoS One and Genome Biology.
It’s a significant undertaking as the majority of previous research has focused on only those bugs that can potentially cause disease. The current study hints at the enormous scope of a person’s microbial rainforest while highlighting emerging view that these bugs, both pathogenic and non-pathogenic, actively participate and contribute to our metabolism and are critical for our ongoing health and survival.
To give you a taste of the “complex combinations” of these microbial partners of ours, The New York Times has published this impressive ‘family tree’ illustrating their prevalence and abundance.
How speeding up chemical reactions is sort of like getting a date, and five ways that they are a similar sort of match-making.
-Prepared Bacterial Cultures in Broth Tubes & on Agar Slants
-Prepared Streak plate
Photos of my prepared inoculated media from last week. Obviously I transferred too much bacteria to the media (otherwise those plate streaks would be really thin and there would be tiny dots - colonies - which there were but only very few). It was ok though since it was the first time I’ve ever done so. What was important was that it wasn’t contaminated by anything other than the desired culture.
Specimens grown are Escherichia coli (E. coli) & Staphylococcus aureus (S. aureus)
