TABLE 3.

Summary of glycan attachment by low pathogenic avian influenza viruses based on the literature^a

^aThis table summarizes previous studies on LPAIV-receptor attachment and lists glycan structures for which the attachment pattern to LPAIVs has been investigated in at least two glycan attachment studies. For each study, a positive score is listed for a receptor-subtype combination if >10% of the maximum attachment per subtype was observed (i.e., numerator). For each receptor-subtype combination, the number of studies is listed (i.e., denominator). –, receptor-subtype combination not investigated.
