MBL2 and urinary tract infection: Infants without measurable MBL levels suffered more frequently from stomatitis and urinary tract infection than infants with normal/low MBL levels (p1 normal vs. not measurable, p2 low vs. not measurable; stomatitis: p1 = 0.006, p2 = 0.02, urinary tract infection: p1 = 0.007, p2 = 0.006, Table 6, Fig 1).
