Fiv occurs worldwide , but is more prevalent in certain geographic areas .
fiv在世界各地都有发生，但是会在某一个区域特别的流行。
Previous studies have suggested that a protein called trimcyp is what keeps humans and monkeys from being infected with fiv .
以往的研究表明，一种称为trimcyp的蛋白质使人类和猴子，不会被fiv所感染。
Poeschla and colleagues next plan to test whether the cats are resistant to fiv , or , if not , whether they are less likely to develop feline aids after infection .
Eric poeschla , a molecular virologist at the mayo clinic in rochester , minnesota , wanted to figure out if giving cats the trimcyp gene would make them immune to fiv .
Researchers can use the same method to test whether other antiviral proteins from humans and monkeys affect the transmission of fiv , says veterinarian susan vandewoude of colorado state university in fort collins .
