carbohydrate analysis showed that the lps of the phage-resistant strains lacked o-antigen sugars ( rhamnose , xylose , and n-acetylglucosamine ) and could be grouped into ( i ) those that had all core sugars ( rhamnose , glucose , heptose , and 2-keto-3-deoxyoctonate ) , ( ii ) those that had no core rhamnose , and ( iii ) those that lacked all core sugars except for 2-keto-3-deoxyoctonate .
