According to these figures, incidence of disease decreases as apiary size increases:

NY Apiary Statistics (AFB) 2002

Apiary Size 		Apiaries 		Colonies 		AFB Colonies 	Disease Rate
01-10			405			1565			89 			5.67%
11-20			90			1361			44 			3.23%
21-30			73			2018			86 			4.26%
31-40			68			2766			34 			1.23%
41-50			8			379			00 			0.00%
50+				41			3593			06 			0.17%

Statewide
Apiary Disease Rate 14.75%
Colony Disease Rate 4.50%

Of course, this is more likely tied to beekeeper skill level than some other factor.
