    Question UV/Sunlight and Crypto


    LOG IN TO CLOSE THIS AD   


    I've been reading up a lot about leopard gecko health tonight and crypto really got me worried, seeing how it is nearly impossible to get rid of according to what I've been noticing in the threads on it here.

    I know that sunlight can kill a lot of things (the only reason I thought of it was because of all the talk of the novel coronavirus and disinfecting with sunlight), so I decided to look it up and found this article. The link is here, and the title itself is, "Usefulness of Sunlight and Artificial UV Radiation Versus Chlorine for the Inactivation of Cryptosporidium Oocysts: An in Vivo Animal Study."

    It should be kept in mind that this is with water, and UV/sunlight travels differently through water than the air, but the results section says:

    "Cryptosporidium oocysts failed to induce any noticeable infection after 4 hours of artificial UV exposure that provided a UV dose of 10mJ/cm2 and after an 8 hours exposure to sunlight, whereas they showed resistance to disinfection by chlorine."

    and the conclusion states this:

    "The results of the study demonstrate the important role of an 8 hours sunlight exposure of potable water in plastic bottles in achieving complete inactivation of any contaminating Cryptosporidium oocysts, thus offering an applicable, economical and convenient method for the control of cryptosporidiosis especially in developing countries."

    Since ammonia is the best way to kill off the oocysts that I've seen discussed here, I am wondering if they could be killed off through a cleaning with ammonia at recommended concentrations AS WELL AS 8+ hours in sunlight or 4 hours of UV exposure at the levels listed (which I don't think you could be certain of without proper equipment).

    If this is something that's come up before, I apologize! I tried searching before posting and didn't manage to find anything about it.

    What are the thoughts on this? Have you seen similar research? I didn't dive much deeper once I found this since it's past midnight where I'm at!



    Edited to add: there are a bunch of suggested/related articles in the sidebar of PubMed at that link that are on the same topics, I'm just that tired I didn't notice until I looked at the page again!

    That was done under strict lab conditions, using precise equipment. It's unlikely you'd be able to duplicate the results in your own home. It also won't do anything to kill the crypto that's inside your gecko. One good poop, and you'll have to disinfect the enclosure, again.

    Also, UV light can be dangerous in high enough doses, and UVC, which is the artificial UV they used, can be downright dangerous, cause skin cancer, "fry" your eyes, and lots of other damage.

    Ah I think I wasn't as clear as I thought in my original post-- I'm talking about disinfecting things, not about trying to treat an animal with it!

    When I have had to disinfect for crypto, I clean with ammonia and let those things air dry outside, so they do get the sunlight that the article is proposing. I have actually never seen recommendations to disinfect for crypto with chlorine. Ammonia is the item of choice and some say that hydrogen peroxide is effective as well. To that end, when I clean the tiles my crypto infected geckos (meaning all of my geckos) use for pooping, I use hydrogen peroxide. I don't think that you have to disinfect everything you ever use for your gecko. If you use ammonia + sunlight to disinfect any new item you're putting in your gecko enclosure and if you have your gecko tested for crypto, you'll probably be OK.
