CDC Says Beware of Pool Parasite - http://clapway.com/2015/06/27/beware-of-pool-parasites564/

The swimming pool is not always your friend, so be wary of a pool parasite


Lately, there have been lots of water-based bacteria cases and warnings popping up in the news. Now, the CDC issued out a warning for the newest parasitic threat in your swimming pool, Cryptosporidium.

This pool parasite, most easily known as ‘Crypto,’ is the cause of many diarrhea-type symptoms. The parasite is quite well-adapted, as it infects animals as well as humans. Further proof of its Darwinian prowess: it’s surprisingly resistant to chlorine disinfection, and it is protected by an outer shell that allows it to survive for longer periods of time. The pool parasite also causes vomiting, which then can lead to severe dehydration and loss of fluids that may require hospitalization.

Other parasites such as E.coli are easily disposed of in a chlorine treatment. However, these Crypto parasites can survive for up to ten days in chorine-treated water because of the aforementioned exterior shell.


Are the joys of swimming gone now?


Not necessarily; the key is to be careful and wary, especially with children. The chief of CDC’s Health Swimming Program, Michele Hlavsa, said “With these outbreaks, we can see they disproportionately affect young children. They’re the ones who can go to a pool and young children tend to carry lots of germs.”

There is also the consideration that young children’s immune systems are not up to snuff with full grown adults’ immune systems when it comes to taking on the pool parasite.


For the children’s sake, watch out for the pool parasite


Swimmers may bring this parasite into the pool with them if they have contracted it, and although it can be gone within a couple of weeks, those with weak immune systems may have more extreme, if not life-threatening, reactions. This is due to the loss of fluids from vomiting and diarrhea robbing your body of the nutrients it needs to function.

To help avoid contracting the pool parasite or having a close one catch the infection, there’s one main step to take- please check to see if the pool you’re thinking of going to was examined by the health department.



 


If you’re going to the pool as a way to get some healthy Sun exposure, there’s a way to do that indoors now, with the LifeLight.

Ramisyllis Multicaudata: The Worm with Many Butts - http://clapway.com/2015/06/21/ramisyllis-multicaudata-the-worm-with-many-butts765/

Recently, butts have been all the rage.


We always see Kardashian butts, Bey butts, J-Lo butts, Nicki Minaj butts everywhere. So, the more butts the better, right?


How ’bout some worm butts?


A friend just told me (let’s call him Gordon) about a sea worm with endless butts- the Ramisyllis multicaudata.


Apparently, in the 18th century, a sea sponge was dredged up by a ship, and in those tiny holes that all sponges have, there was a living creature. A worm with endless butts. Now, this worm is a rare find, and no one knows much about it. It’s a branch-worm. It grows by spreading its body out into trees.


Worm with many butts is an Aussie parasite


Primarily found in Australian waters, this little guy is definitely a parasite to the sea-sponge. However, the worm with many butts is otherwise huge mystery to scientists. What can be said is that it is largely independent from other branched species (meaning it didn’t evolve to grow limbs or—in this case— butts from another genus). It just evolved to spread its body out in to tiny webs that fill the cavities of sponges.


But why butts? What is known about the worm is that it has one head, but then each extremity can independently grow more branches until the entire host-sponge is filled to capacity! In fact, multitudo means many, similar to multitude, and you can see this classification in other species. One such species is the two-tailed swallowtail butterfly. Many ends. Many tails. Many butts.


The relationship between the host and the worm with many butts is unknown.


We are still not even sure if it the relationship is a symbiotic one, like that between sharks and pilot fish, or if the worm is slowly killing the sea sponge. It seems that, either way, the branched butts absorb nutrients to allow the worm to support itself. It makes sense, because how can one head feed that large a body?


I, for one, have never been more interested in butts. The potential this guy has is only beginning, and I think he has a lot to show us. I’m looking forward to hearing more about Ramisyllis multicaudata: the worm with many butts.
