To explore the connections between ocular infection and concurrent urogenital tract (UGT) infection, we evaluated UGT C. pecorum positivity in a subgroup of 96 koalas from cohorts H1 to G3 (18 swabs from group H1, 32 from H2, 14 from G1, 21 from G2, and 11 from G3) who underwent paired ocular and UGT swab collection. This evidence concerns the gene SLC35A2 and eye infection.
