Day 26, competition! One way to out-compete other bacteria is to simply grow faster! In optimal conditions, E. coli can duplicate every 20 minutes

25: TRANSPOSON

Also known as jumping genes, they’re a handy tool in a many pathogen's toolkit. Transposons give Cryptococcus neoformans the genetic room it needs to adapt & resist antibiotics during infection.

24: ZOONOTIC

Sometimes we're incidental hosts to pathogens. Ebolaviruses mostly infect non-human primates & bats. Our Ebola outbreaks start w. a spillover from these animals, before human to human spread takes over

DAY 24 // ZOONOTIC

22 - Persistance!

The real persister here is YOU! Microbiology is a hard line of work with a lot of failures - failed experiments are a part of science. But you keep going for it and that's amazing! Go you!

The Bacteria Collection: Pyrococcus furiosus (5/8) ✨

Day 16 of the list.
Prompt: Extremophile

Day 21- Plasmid. These rings of DNA are often shared among bacteria, and are a major contributor to the spread of antimicrobial resistance! Hence, one plasmid to resist them all...

20: LUMINESCENCE

Yes, there are luminescent pathogens too... Vibrio harveyi causes luminescent vibriosis in farmed shrimp. This may involve widespread necrosis in their appendages, but what a pretty colour!

Inktober/Microber 2021 Day 20 Luminescence 👻🦠
Bioluminescence is the emission of light by a living organism. Among the bacteria, Aliivibrio fischeri is one of the best known examples.💡

18: MOTILITY

Proteus is a catheter opportunist with a bullseye motility pattern, due to cycling btw vegetative & swarmer states. A switch to swarming causes massive elongation, many more flagella & all the nasties!

A classic motility assay, but cute-ified 🥰

14: CHEMOTAXIS

Helicobacter uses chemotaxis to swim towards some tasty sugars on the lining of the stomach, and finds its home there for life

A little bug who is all for that sugar rush 🍭🍫🍩

Inktober/Microber 2021 Day 13 Division 👻🦠
Bacteria multiply through cell division - most undergo a process called binary fission resulting in two daughter cells. 👯

12: DIVISION

In their infectious form, these brain-eating amoebae can divide without breaking up their nuclear membrane, in a process called promitosis.

The Bacteria Collection: Clostridium tetani (2/8) ☄️

This was day 6 of the list. Prompt: Sporulation.

12 - Wall!

The cell wall protects a bacterium and is mostly responsible for its shape. Penicillin is an antibiotic that interferes with cell wall construction enzymes and causes the cell to lyse.

DAY 12 // WALL
Who doesn’t love a good ol’ Gram stain?

11 - Streaking!

When bacteria are treated with lysozyme and penicillin, they can go into an L-form state in which they don’t have a cell wall.

This is a cheap joke and I know it but I could not help myself. I giggled while making it.
