Now that we know that some Lyme-causing Borrelia are closer, genetically speaking, to relapsing fever Borrelia than to the Borrelia burgdorferi sensu lato group, maybe this explains why Lyme can sometimes be transmitted within just a few hours of a tickbite, or even "as soon as they bite" (see below.
Relapsing fever borrelia evolved in nature to spread via soft ticks such as the Ornithodoros ticks, which tend to feed for a very short time, and can transmit their "payload" in just a few minutes.

Title:Disseminated Lyme disease after short-duration tick bite Authors:Patmas MA, Remorca C Source:JSTD 1994; 1:77-78
Abstract: Lyme disease, an Ixodes tick-borne spirochetal infection, has been the subject of much controversy. One problematic area has been the prophylactic treatment of deer-tick bites in endemic areas. Some have argued against routine antimicrobial prophylaxis based upon the belief that transmission of Borrelia burgdorferi is unlikely before 24-48 hours of tick attachment. Others have suggested that it is cost effective to administer prophylactic antibiotics against Lyme disease when embedded deer-tick bites occur in endemic areas. Herein, a case of disseminated Lyme disease after only 6 hours of tick attachment is presented. The current recommendation against treatment of short-duration tick bites may need reconsideration, particularly in hyperendemic areas. Color pictures.
----- While it is true that it takes the spirochete some time to travel to the salivary glands from the tick's midgut where it resides, at the Lyme Conference, Willy Burgdorfer described a study in which they found 5 to 10 percent of ticks already have the spirochete in their salivary glands. That means they transmit the disease as soon as they bite..

Yeah- one creepy thing about the soft ticks that I had not even known for along time is that they tend to be nocturnal and come out at night and feed and then go away!!! So you may not even find a tick on you!! Ugh!! Creepy!!!

I never bought into the "must be attached 24 hrs" to become infected theory anyway.
What is the tick doing the first 23 hrs? Saying grace over his meal?

I heard my doctor saying that it takes 2 hours for the tick to start to regurgitate (is this English?? )... That's when most pathogens invade our blood.
So it's possible that after 1 hour, one could be still safe. (?) But if it carries the pathogens in its saliva, well, I don't think one could consider safe 100%.
the two hour theory (or around) seems to be so far, the only one I could 'believe', because of the time the tick takes to digest the blood and send it out again.
But I would be watchful even for less than 2 hours, for sure, if they have the pathogens in their saliva!! I myself was infected first time after a more than 24 hours bite, but the second time, it was much less (about 9 hours, if my memory is good).
And I swear this second bite infected me with many many pathogens, not only borrelia. It took me less than 48 hours after bite to fall sick again.
My daughter, it was less than 24 hours too (she was bitten in her head in an afternoon, I got the tick early morning next day). She fell sick from day one.
Wikipedia saying it takes 48 hours.... It's a joke!
