    Disease transmission via aerosol

    Waterborne diseases can travel through the air infecting nearby tanks? Yeah, I didn't believe it at first either. I first heard of aerosol transmission from "billsreef," a highly respected Marine Biologist who posts on Reef Central. He had this to say:
    This got me thinking. From my own experience and that of others, I've experienced cases where a display tank (DT) inexplicably got ich. In each case, there was a quarantine tank (QT) in close proximity to the DT. Further research on the matter turned up this study (Roberts-Thompson et al 2006): Aerosol dispersal of the fish pathogen, Amyloodinium ocellatum

    The abstract of which is as follows:
    Conclusions:

    Amyloodinium's (aka Marine Velvet disease) dinospore stage is similar in nature to the "free swimming" stage of other external parasites. Cryptocaryon irritans (aka Marine Ich) has a theront stage, for example. Therefore, it is logical to conclude that these are transmissible via aerosol as well.

    The study found that dinospores could travel in aerosol droplets up to 3 meters (or 9.84 feet) with dynamic systems. Well, any aquarium with flow/bubbles breaking the surface can be considered "dynamic." So in light of this, I feel it is advisable to house your QT at least 10 feet away from the DT. This also applies to any other two tanks that you want to ensure no cross contamination can occur between them. It is well established that "anything wet" such as hands, feeding apparatus, etc. can cross contaminate diseases & medication from one tank to another. Now we know that aerosol droplets can do the same. I think it is also very possible for medications in the water to be transmissible via aerosol droplets. No one wants copper in their reef tank! :(

    as soon as I saw your title I had to read

    we have yapped online before in other threads specifically about aerosol xmissions of nitrifiers, cyano and various forms of algae. enter in ubiquitous hitchhikers stage left its fascinating vector biology.

    and the next wow is dry aerial floc bringing in essentially 'wet' biologist organisms and mixed aerobes to inoculate any body of water with the filter seeds and food (colonies that bloomed unsuited for the space) required. Any aerial vectoring can woo me. regardless of who on rc showed you the details its fun science. I was reading once where Niagara alone vectors out hundreds of miles and into the jet stream.

    Hey Ethiopia, here's some gram negs from US/Can enjoy

    Well from a biology/infectious disease stand point a human sneeze would be pretty similar the fine mist that tanks generate but other than that I can't say much esle. I would be somewhat doubtful of how well it would work because most things that use aerosol transmission are evolved in a way that is conducive to it, marine disease would have no use or experience with this so they would not be geared for it.

    Its more then my opinion it is my experience. I will love to hear why you think he is such a great biologist. Was it a paper he published, article he wrote ,research he conducted or that he talks a big game on fourms.

    Sounds like one of his BS stories. Bill is so much smarter then the professor he was working for.The professor should have listened to Bill. BLAH BLAH BLAH. He is the biology version of the keyboard ninja.

    I'm sorry... but I'm locking this. The intent of this thread is to inform/discuss the aspects of aerosol transmission. Not turn it into "Let's Bash Bill" to satisfy someone's personal vendetta.
