Introducción. La psitacosis es una enfermedad zoonótica causada por Chlamydia psittaci. Esta bacteria es catalogada como un agente con potencial bioterrorista y ha causado múltiples brotes en trabajadores con exposición laboral a aves en diferentes lugares del mundo. En Colombia, no se hace seguimiento epidemiológico de la infección y existe una gran brecha en el conocimiento.Objetivos. Determinar la frecuencia de anticuerpos contra C. psittaci en trabajadores con exposición laboral a aves y sus factores asociados. Además, revisar la literatura en relación con los estudios sobre el tema realizados en Colombia.Materiales y métodos. Se llevó a cabo un estudio descriptivo, transversal, con intención analítica, en trabajadores en contacto con aves y se revisó la literatura científica relacionada en Colombia. Se detectaron anticuerpos IgM e IgG contra C. psittaci en suero por microinmunofluorescencia. La descripción de las características sociodemográficas y de exposición se hizo con frecuencias y medidas de resumen. Se exploraron factores asociados por análisis bivariados y multivariados. La revisión de la literatura científica y gris se hizo con búsqueda estructurada.Resultados. Se analizaron 54 trabajadores en contacto con aves y se encontró una prevalencia de anticuerpos del 31,5 %. El ejercer funciones de sacrificio y faenado de las aves sin ser médico veterinario fue un factor de riesgo para la presencia de anticuerpos. Solo se encontraron cuatro estudios previos sobre C. psittaci hechos en Colombia.Conclusiones. Este estudio constituye la primera evidencia de la circulación de C. psittaci en trabajadores en contacto con aves en Antioquia y el segundo reporte en el país. Estos hallazgos aportan desde la salud pública a la estrategia One Health.

“…En los cuatro estudios encontrados, se reportó la presencia directa o indirecta de la bacteria en aves. En dos de ellos se encontraron prevalencias entre el 79 y el 90 % 25 , 29 ; en uno se indicó una prevalencia del 25,4 % 28 y en el último solo se detectó un ave positiva de las seis estudiadas 27 ( cuadro 5 ).…”

“…Our environmental sampling strategy was based on guidance developed by USDA for environmental monitoring of avian influenza (APHIS, 2022), which might not be entirely applicable to C. psittaci Limitations of environmental testing should be accounted for during investigations. First, faecal swabs have a lower detection sensitivity compared with cloacal swabs (Balsamo et al, 2017;Ruiz-Laiton et al, 2022), and should therefore be conducted in parallel to swabbing individual birds, as was done in this investigation. Ideally, birds should be tested for chlamydial DNA no less than 6-10 days after the end of antibiotic treatment to confirm that treatment was successful (Guzman et al, 2010).…”

Chlamydia psittaci is a bacterium that causes chlamydiosis in birds and can cause zoonotic psittacosis in people. In November 2017, we received notification of a suspected case of avian chlamydiosis in a captive cockatiel (Nymphicus hollandicus) that was sold by an online pet bird retail and breeding facility in Washington State. We describe the investigation with emphasis on how environmental sampling was used to guide veterinary and public health interventions. Bird samples were collected either from pooled droppings, pooled plumage or individual nasal and choanal swabs. Environmental samples were obtained by swabbing cleaning mops, tables and cage structures. All samples were tested by polymerase chain reaction and positive samples underwent genotyping. Approximately 1000 birds representing four taxonomic orders were kept within an open‐space warehouse. Eight of 14 environmental samples and one of two pooled faecal samples were positive for Chlamydia spp. The contaminating strain of Chlamydia spp. was identified as genotype A. The facility was closed for environmental disinfection, and all psittacines were treated with oral doxycycline for 45 days. Ten of 10 environmental and two of two pooled faecal samples were negative for C. psittaci 11 months after the completion of environmental disinfection and antimicrobial treatment. This investigation highlights the importance of preventing and mitigating pathogen incursion in an online pet retail and breeding facility. Environmental sampling is valuable to guide animal and public health interventions for control of C. psittaci, particularly when large numbers of birds are exposed to the pathogen.

“…Finally, E/B, WC and M56 genotypes were detected in ducks, Wolfsen cattle and muskrats, respectively. All genotypes are potentially transmissible to humans, and they can cause severe disease and even death [ 6 , 7 , 8 , 9 ].…”

“…In fact, the culture of C. psittaci represents a laborious, time-consuming technique, and it requires a level 3 biosafety facility in laboratory [ 14 ]. Serological tests are used for diagnosis, which are still non-specific and difficult to interpret [ 6 , 7 , 8 ]. Other methods, such as immunochemistry, are actually used for the detection of this pathogen in cytological and histological preparations [ 14 ].…”

Chlamydia psittaci is an intracellular bacterium belonging to the Chlamydiaceae family. It is the ethiologic agent of psittacosis, an occupational zoonotic disease that mainly concerns people who work in close contact with birds that represent the main infection route for human transmission. In Italy, information about this disease is lacking. This study is the first case of avian chlamydiosis reported from a pet shop in Sardinia, Italy. Chlamydia psittaci detected in psittacine birds by molecular analysis, direct immunofluorescence test together with anatomo-pathological observed lesions, highlighted the importance of focusing the attention over this underestimated zoonosis in a “One Health” prospective.
