Bio-warfare in the American Revolution?

Hmmm, an interesting theory, but I am doubtful.  The Quebec operation cited was essentially a sneak attack, strategically, and I'd be surprised if sending a mob of diseased prostitutes out would be the type of response one comes up with under such circumstances.  The fact is, that whenever one gathered together an army, between the regular troops and the camp followers you were guaranteed to have one or more communicable diseases.  And within a short time, they'd be running rampant through your camp, disabling or killing a fair amount of your strength.  After 30-90 days, the various plagues would have run their course, killing off most of the people they were likely to, and THEN you could march off to war, (praying that you didn't have to add replacements later on, which would start the whole process all over).  The British didn't need to infect newly formed American armies, (like at the siege of Boston).  Drawing troops and those who accompany them from every town and field in New England would guarantee that culling would happen, regardless.  This is one of those examples of how we live in a totally different world now.
