Here is an interesting article that demonstrates a link between the diversity of the bacteria found on somebody's skin with their likelihood to attract the mosquitos that serve as vectors for malaria. The diversity was determined by comparing 16SrRNA sequences, determined by pyrosequencing (which, of course, was not a technique we covered in the last lecture). It turns out that a high abundance, and low diversity of bacteria is more attractive to the mosquitos. In a similar, but more disgusting, study, it was revealed that the mosquitos are also attracted to "smelly feet".
