Avian Chlamydia abortus Strains Detected in Galápagos Waved Albatross (Phoebastria irrorata)

Abstract:

Galápagos Penguin (Spheniscus mendiculus), Flightless Cormorant (Phalacrocorax harrisi), and Waved Albatross (Phoebastria irrorata) are among the most vulnerable species to natural and anthropogenic factors in the Galápagos Islands. In 2017, a dedicated study was conducted to detect Chlamydiaceae on cloacal swabs collected from 59 albatrosses, 68 penguins, and 10 cormorants in different islands and sites in the Galápagos Archipelago. A real-time PCR method targeting the conserved 23S ribosomal RNA gene of the Chlamydiaceae family detected the presence of the bacterium only in albatrosses from Punta Suárez, Española Island, with 21 positive samples (35.6%), whereas negative results were obtained with available real-time PCR systems specific to Chlamydia psittaci and Chlamydia abortus. Multilocus sequence typing (MLST) of the most strongly positive samples revealed a new sequence …
