Positives Are Violet In Color And Negatives Are Red Or Pink On Gram Stain! My Untidy Handwritten Notes

Bacterial strain X is resistant to Ampicillin and sensitive to Gentamycin. Bacterial strain Y is resistane to gentamycin and sensitive to Ampicillin. Bacterial strain X and Y are grown in mixed culture in medium without antibiotics, then the culture is plated on medium containing both ampicillin…

If you cannot grasp what I have just explained, you should just leave and study economics!

Stuff in my Office

From 1930. This well-dressed young scientist is experimenting with The Air. Exactly what he is doing is a mystery.

July 25 …. I finally get it!  He’s holding an eye dropper with a bulb on the end. I thought it was a pair of chopsticks! He’s picking up pieces of paper using the vacuum from squeezing the bulb! Still very formal, though …

20.1.18 // studygram: alimastudies

i don’t normally upload pictures of my homework because i don’t tend to spend a lot of effort or time on them as i know i won’t be using it again, but for this biology homework i thought i would do it nicely and use it for my future notes! i need to work on my handlettering oh dear god ahhh i used a crayola supertip for it

Neisseria gonorrhoeae

PMN filled with Neisseria gonorrhoeae => Gram- diplococci, glucose fermenter, non maltose fermenter, oxidase positive.

Very inflammatory response: exudate with high number of PMN. TX with ceftriaxone and always ALWAYS test for Chlamydia trachomatis (since is more common and exudate is similar)

How to tell them apart? 

N. gonorrhoeae’s exudate is more purulent than C. trachomatis.

N. gonorrhoeae’s exudate is “greenish-yellowish” but C. trachomatis’s is whiter.

N. gonorrhoeae is always inside a PMN while C. trachomatis is not 

Grows in Thayer-Martin medium (chocolote agar + antibiotics, is a selective medium)

Remember to use your sponge to replace any bacteria on your dishes accidentally removed by the act of eating.
