Chlamydia Species and Related Risk Factors in Poultry in North-Western Italy: Possible Bird-to-Human Transmission for <i<C. gallinacea</i<

<i<Chlamydiaceae</i< are obligatory intracellular bacteria causing acute and chronic diseases in animals and humans worldwide, with recently discovered species with a still unclear pathogenic potential (i.e., <i<C. gallinacea</i<). In Italy, <i<Chlamydiaceae</i< i...

520			\|a <i<Chlamydiaceae</i< are obligatory intracellular bacteria causing acute and chronic diseases in animals and humans worldwide, with recently discovered species with a still unclear pathogenic potential (i.e., <i<C. gallinacea</i<). In Italy, <i<Chlamydiaceae</i< infections are underestimated both in animals and humans. To estimate the prevalence of <i<Chlamydiaceae</i< species in poultry and occupationally exposed workers on farm, a cross-sectional study was carried out in north-western Italy. A total of 2063 samples from 83 commercial and 31 backyard poultry farms were analysed using real-time PCRs for <i<Chlamydiaceae</i< screening and species typing. <i<Chlamydiaceae</i< were detected in 23 farms, with a herd prevalence of 20.2% (95%CI: 13.2–28.7), higher in backyard farms (38.7%; 95%CI: 21.8–57.8) compared to commercial ones (13.3%; 95%CI: 6.8–22.5). <i<C. gallinacea</i< was found in 18 chicken farms, both commercial and backyard, and <i<C. psittaci</i< only in 3 backyard farms. Exposure to wild birds and factors related to biosecurity resulted the main risk factors associated with <i<Chlamydia</i< positivity. Out of the 113 sputum samples collected from farmers, 16 tested positive to <i<Chlamydiaceae,</i< with a prevalence of 14.2% (95%CI: 8, 3–22). To the best of our knowledge, for the first time at international level, <i<C. gallinacea</i< was detected in humans with farmer positivity associated with farm infectious status, suggesting a bird-to-human transmission.

In Italy, <i<Chlamydiaceae</i< infections are underestimated both in animals and humans. To estimate the prevalence of <i<Chlamydiaceae</i< species in poultry and occupationally exposed workers on farm, a cross-sectional study was carried out in north-western Italy. A total of 2063 samples from 83 commercial and 31 backyard poultry farms were analysed using real-time PCRs for <i<Chlamydiaceae</i< screening and species typing. <i<Chlamydiaceae</i< were detected in 23 farms, with a herd prevalence of 20.2% (95%CI: 13.2–28.7), higher in backyard farms (38.7%; 95%CI: 21.8–57.8) compared to commercial ones (13.3%; 95%CI: 6.8–22.5). <i<C. gallinacea</i< was found in 18 chicken farms, both commercial and backyard, and <i<C. psittaci</i< only in 3 backyard farms.

abstract	<i<Chlamydiaceae</i< are obligatory intracellular bacteria causing acute and chronic diseases in animals and humans worldwide, with recently discovered species with a still unclear pathogenic potential (i.e., <i<C. gallinacea</i<). In Italy, <i<Chlamydiaceae</i< infections are underestimated both in animals and humans. To estimate the prevalence of <i<Chlamydiaceae</i< species in poultry and occupationally exposed workers on farm, a cross-sectional study was carried out in north-western Italy. A total of 2063 samples from 83 commercial and 31 backyard poultry farms were analysed using real-time PCRs for <i<Chlamydiaceae</i< screening and species typing. <i<Chlamydiaceae</i< were detected in 23 farms, with a herd prevalence of 20.2% (95%CI: 13.2–28.7), higher in backyard farms (38.7%; 95%CI: 21.8–57.8) compared to commercial ones (13.3%; 95%CI: 6.8–22.5). <i<C. gallinacea</i< was found in 18 chicken farms, both commercial and backyard, and <i<C. psittaci</i< only in 3 backyard farms. Exposure to wild birds and factors related to biosecurity resulted the main risk factors associated with <i<Chlamydia</i< positivity. Out of the 113 sputum samples collected from farmers, 16 tested positive to <i<Chlamydiaceae,</i< with a prevalence of 14.2% (95%CI: 8, 3–22). To the best of our knowledge, for the first time at international level, <i<C. gallinacea</i< was detected in humans with farmer positivity associated with farm infectious status, suggesting a bird-to-human transmission.
