There is a contradiction in the first block of text: it is stated that more than 30 species are reported to infect animals and humans, while in the next sentence it is claimed that only around 10 have been known to infect humans. I ask of anybody who knows about the subject to correct this. —Preceding unsigned comment added by 22.214.171.124 (talk) 21:35, 17 May 2011 (UTC)
