Popis: Nine Chlamydia suis isolates, obtained from pigs with conjunctivitis, were molecularly characterized by ompA sequencing and their in vitro susceptibility to six cathelicidin peptides (SMAP-29, BAC-7, BMAP-27, BMAP-27, BMAP-28, PG-1, LL-37) determined in cell culture. SMAP-29 was the most active peptide, reducing the intracellular inclusion number by ≥50% at a concentration of 10 μg/ml (3 μM) in six of the nine isolates tested. Three molecularly identical isolates were insensitive at a concentration as high as 80 μg/ml (25 μM). Of the remaining cathelicidin peptides tested, BAC-7 and BMAP-27 were active against six C. suis isolates at a concentration of 80 μg/ml (25 and 26 μM, respectively). Cathelicidins LL-37 and PG-1 did not show any anti-chlamydial activity at 80 μg/ml.
