Cellulitis infection

Both authors of this site have had cases of cellulitis, so we can get particularly intimate with this subject. Let's get down to it. Cellulitis is a bacterial skin infection. It usually starts innocently enough with a little redness and perhaps some swelling. If left untreated, things can go south quickly. This is what happened [...]

spider bites

Who doesn't have an outsize fear of spiders? The things look they were specifically designed to terrify us. Eight legs, eight eyes, fangs. What else? Oh yeah, some of them are venomous.

fire coral

Here's the deal, fire coral is not even coral. It's worse than that. Fire coral is actually more closely related to jellyfish than coral.

is my heartburn from doxycycline permanent?

I previously wrote about why I stopped taking doxycycline as a malaria prophylactic. That was back in 2011. I had just finished a trip through West Africa at the end of 2010, and I had returned home to the states before setting off on the road again. Originally, I thought I was having a problem [...]

Roundworms are a type of nematode, which are considered to be the most numerous form of multicellular organism on earth. They are parasites of a variety of different organisms, [...]

The candiru (also known as the Toothpick Fish or the Vampire Fish) has long been reputed to be capable of swimming up a person's urethra during urination in affected waters, causing untold physical harm and psychological trauma. We mentioned in our 7 terrifying small organisms piece that the candiru was known to have gone up [...]

I hate sand flies

sandfly bites

Suppose you were Mother Nature, and you wanted to devise a creature that was fundamentally irritating. What would you create? Well, the sandfly would be a good place to start. Known variably as the sand gnat, biting midge, sand flea or no-see-um, sand flies are small enough that they wouldn't seem like a nuisance. What [...]
