Agreed...kinda.
But spirochetes are bacteria..and bacteria could survive in the air for a few seconds. Which is all that's needed to transmit / infect.
Very interesting piece on Spirochetes in general. The whole page is interesting, but just a small excerpt :

Spirochetes are in many ways more evolved than other bacteria. At times they almost exhibit animal-like tendencies. Borrelia bacteria have an internal propulsion system that allows them to be highly motile. This is an evolutionary advantage over nonmotile bacteria that allows Borrelia to seek out those areas in a host that are best suited to its needs. The spirochete can swim as easily forward as it can backward, and it now appears that there are receptors for host tissue in both tips of the spirochete. This allows each end of the bacteria to seek out sites of attachment as well as change direction when a better target is located.
The most important adaptation, however, may be the recently observed phenomena that Borrelia burgdorferi may have many morphogenic states and can change their appearance both in shape and chemical structure. Morphogenic changes is another way of saying that the bacteria can adapt itself to the host that it happens to be in, such as a tick, a mouse, or a man. These morphogenic changes may be as subtle as the absence of one surface protein from one division to the next, or, as some have suggested, the spirochete may shed its cell wall entirely and become a spherical-shaped blob, devoid of many of its proteins.
Borrelia bacteria appear to have several layers of protection not commonly seen in other bacteria. One such layer is a glyco-protein gel coat (the S-layer is not commonly seen in-vitro), which has been described as a kind of jelly which can encapsulate the bacteria. Beneath this lies a cell wall, and beneath that is a three-layer membrane. Embedded within the cell wall and membrane are a variety of proteins. Some of these proteins are now known to be receptors to attach to certain host tissues and cells. More insidious in nature are those proteins on the outer cell membrane that seem to be present to purposely fool the immune systems of mammalian hosts.
There was also an episode on animal planet's 'Monsters Inside Me' , (season 1 or season 2) in which a firefighter died from breathing in a brain-eating parasite... They basically blamed his immune system for being susceptible to it...and saying how it's very rare and all that. But still it happened, and i'm curious as to the name of that particular type of parasite. Tried google searching, but found nothing. (so far)
EDIT : found it.

Sometimes the smallest parasite can take down the bravest host— and while battling wild fires in California, a veteran firefighter develops flu-like symptoms and finds himself in a battle against something far more dangerous then a fire— a rare amoeba that lives in the soil that has attacked his brain.
