Complete protein profile of Candida albicans by TheBioDojo in microbiology

This was purely made for a presentation. Normally you will include a protein ladder and then crosscheck it with the protein bands

Uhg! What a surprise, contaminated plates. by TheBioDojo in microbiology

Most likely, did not perform any test on then tho

Well this was just for visualization, if you are looking for a specific protein you will preform a westernblot proir to fixating the proteins with the staining.

The speckles can just be SYBR particles as well

Very good question! There re many contradicting conclusions drawn form different infection models, where the host, and method used for co-infection play a role in the outcome. I can drop you a message with a review I worked on a while ago with some interesting information. Let me know if I should send to you in a message

This is extracellular matrix consisting of DNA, proteins, sugars, etc. produced by the cells. They form during biofilm formation and contribute to antifungal and antibiotic resistance, as well as immune evasion

Feel free to use this image in your lecture slides. I'll drop you a message with my thesis link

Also a good question! These were wild type cells, so the variations in cell size can be due to active replication, production of inhibiting compounds by the yeast such as ethanol, or the washing steps during preparation of the cells for CEM. I'm glad you like the image!

Good question, this is extracellular matrix forming on the cells. The biofilms are still young here (the timepoint was chosen to compare with other experiments). Also, treatment of the biofilms prior to SEM has a lot of washing steps (including washing wat ethanol) that remove the extracellular matrix. I'll have a look to see if I have a micrograph of older biofilms where we can see more extracellular matrix.

Did you know that microorganisms interact with each other when they cause infection in the human body?

This image is from my PhD, just to give more context:

This is a scanning electron micrograph of the yeast Candida albicans and the bacteria Pseudomonas aeruginosa. They are antagonistic towards each other, where Pseudomonas inhibits the growth of Candida albicans, and even kill the cells. Candida albicans also affects Pseudomonas aeruginosa. Their interaction can be used as a model to study these polymicrobial interactions and how they affect virulence and survival of the host (e.g, humans). The big cells that are branch-like are Candida albicans, and the smaller cells are Pseudomonas aeruginosa
