Phage types were determined using standard procedures and designations (http://www.geocities.com/avinash_abhyankar/typing.htm). RDNC, reaction does not conform. RDNC Aus1, RDNC Aus2, etc., are identifiable and reproducible phage typing patterns awaiting formal assignment by the WHO-designated International Reference Laboratory at Colindale, United Kingdom. RDNC Aus2 is a 1var variant, and RDNC Aus3 and Aus4 are 3bvar variants.
