In this study, DNA extracted from cloacal swabs of 108 corvids from Northeast Italy was screened for Chlamydiaceae by 23S real-time (rt)PCR. The positive samples were characterised by specific rtPCRs for Chlamydia psittaci, Chlamydia abortus, Chlamydia gallinacea, Chlamydia avium, Chlamydia pecorum and Chlamydia suis. Cloacal shedding of Chlamydiaceae was detected in 12 out of 108 (11.1%, 5.9%-18.6% 95% CI) corvids sampled. Molecular characterisation at the species level was possible in 8/12 samples, showing C. psittaci positivity in only one sample from a hooded crow and C. abortusAnimals : an open access journal from MDPI1226https://www.ebi.ac.uk/biostudies/studies/S-EPMC9137748biostudies-literatureOccurrence of Chlamydiae in Corvids in Northeast Italy.PMC9137748Laroucau KDi Francesco ASchnee CSalvatore DGobbo FLupini CTerregino CAaziz RfalseOccurrence of Chlamydiae in Corvids in Northeast Italy.Chlamydiaceae occurrence has been largely evaluated in wildlife, showing that wild birds are efficient reservoirs for avian chlamydiosis.
