Coral Mucus Makes Bacteria Go Insane! | Reef Receipts

In this episode of Reef Receipts we take a look at a paper studying the effect of coral mucus on bacterial behavior. In short, bacteria undergo major changes in the presence of coral mucus to become more pathogenic.

[@YJestChris]

Love these talks about peer reviewed data on coral pathogens! We need more of these because there is so much conflicting anecdotal data out there to navigate through.

[@jahsreef8386]

Richard Ross just woke up from a nightmare when you started talking about bubble scrubbing 😂

[@REEF4life]

Definitely one of my favorite things you guys do on this channel ❤

[@amandameckley8140]

Loved this so much! You got my head spinning…productive thoughts! 🫶👏💙🪸

[@reefwithmee]

Another one! *DJ Khalid’s voice* Love bacteria topics!

[@bthefountain]

Thank you! I read it in that voice before I even saw that was your intention. 😂😂

[@amir236]

I absolutely love these new videos that bring the more scientific and accurate marine world to the hobby!! keep it up guys , we could use more evidence based information:)

[@kayakcarol]

Very nice suit! Great topic guys.

[@SurfCityCorals-jx3zc]

Yes yes yes @28:30. 100% agreed from a nursing perspective as well when pertaining to law. Different groups of people (facilities) can come to different conclusions at times which means you need a larger sample size. The more consistently you see the same result the more conclusive the evidence is which is why I plant myself at a a subjectively high rated skilled nursing facility. The facilities rated lower have worse outcomes because they don't have the perspective that allows them to see most effective processes to achieve desired results (rehabilitation, improved overall health). "Even though there is a research study out there, there are some very valid criticisms of it just built into that." To your point, being trained in statistics, it is important to analyze all criticisms as well and then analyze results. Evidence based practice is the only way. Amen.

Oxygen: trys always to stay at 8mg/ltr in water, if its more, its given into the air, if less taken from the air.

[@mdbssn]

While it's not really a treatment, I wonder if a combination of carbon (to neutralize the mucus) and UV (to lessen the concentration of bacteria in the water column) would have a statistically significant increase in survival rates with active infections. If it was, maybe that and dropping a couple of degrees of temperature could be a reasonable setup for a hospital tank, where you still need to dip or medicate, but where recovery is much easier.

[@MabuyaQ]

I am not a researcher but I think the system is a bit more complex. I feel that the mucus that a coral produces is mostly consumed and thereby altered by the bacterial holobiont that is thereby protecting the coral. As a first line of defense this altered mucus actually signals pathogenic bacteria to stay away as they won't be able to outcompete the holobiont bacteria and the corals imunesystem. But with a compromised holobiont that system fails as unaltered mucus is then used by the pathogenic bacteria to target that specific coral and put itself in a state where it is first ready to outcompete what is left of the unhealthy holobiont.

[@Fish_Ventura]

Yea thank you for coming back x2. 81F, got it

[@bruhman8005]

Victor at WWC still will turn the tank into a big “skimmer” by putting a couple air stones and turning off return

[@gocedimoski728]

Doxycyclin, ciprofloxacin is still used in europe at coralwholesalers, whats about resistency?

[@MrGarciaJr]

That's a fly suit!

[@EmpireReefer]

Bacteria is our biggest issue in this hobby.. it’s gonna be the key to success

[@951000jerome]

It’s our best weapon.

[@EmpireReefer]

@@951000jerome definitely right about that. Fight fire with fire. The problem is separating the bad ones from the good ones.

[@lorenzobosforo6697]

So I'm not trying to be funny. So if we eat mold that should be good for us?

[@gocedimoski728]

Penicillinium, found on cheese

[@S2minute]

I bet Salem Clemens from Reef Builders would have a say about this.

[@bthefountain]

We have talked about it. ☺️ I love Salem!
