LEfSe analysis identified three genes that encode ABC transporter proteins over-represented within PEDIS 4 infections including K06147 (ATP-binding cassette, subfamily B), K01990 (ABC-2 type transport system ATB-binding protein) and K16785 (energy-coupling factor transport system permease protein EcfT) (p < 0.05). Here, ABCG2 is linked to infection.
