Infection types follow Stakman (1962) where 0, ;, 1, and 2 were considered low infection types, and 3 to 4 were considered high infection types. For combinations, order indicates predominant types, hence 432 is predominantly infection type (IT) 4, with decreasing amounts of IT 3 and IT 2. 2−, small IT 2; 2+, large IT 2.
