Development of a method for the concentration and recovery of microsporidia from tap water.

Microsporidia are obligate intracellular parasites. Microsporidian spores infect a wide variety of hosts, including humans. The spores may be found in infected hosts' urine and feces, thus waterborne transmission is possible.

IL-13 R130Q, a common variant associated with allergy and asthma, enhances effector mechanisms essential for human allergic inflammation.

Genetic factors are known to strongly influence susceptibility to allergic inflammation. The Th2 cytokine IL-13 is a central mediator of allergy and asthma, and common single-nucleotide polymorphisms in IL13 are associated with allergic phenotypes in several ethnically diverse populations. In particular, IL13+2044GA is expected to result in the nonconservative replacement of arginine 130 (R130) with glutamine (Q).
