| description |
Psittacosis is an acute infectious zoonotic disease caused by Chlamydia psittaci (Cps), whose report is mandatory for the doctor and the veterinarian. In humans, suspicion is generally low, since it can present different respiratory and/or extrapulmonary compromise. The commercialization of wild parrots is prohibited in Argentina (Law 22,421), however, when it occurs, they are crammed into small containers, in conditions of animal abuse. It was shown in the province of Córdoba that free birds do not excrete Cps; while they can, under captive conditions. Nine genotypes are known: A-F and E/B related to birds, being A, highly virulent and M56/WC associated with mammals. Objective: To detect the presence of Cps in pigeons, recovered from illegal trafficking, at the Fauna Rescue and Interpretation Center, La Esmeralda, in December 2021.
Samples of 32 individuals have been obtained representative of a total of 90 pigeons . Ocular, oropharyngeal and cloacal swabs were collected from each bird (samples pool) with and without signs compatible with Cps. A portion of the gene encoding 16SrRNA of the genus Chlamydia was amplified by nested multiplex PCR(PCRMA). Subsequently, another nested PCR was performed that amplifies the ompA region to identify the Cps species and the sequences of the PCR products analyzed with the MEGA 5 program.
The 53.3% of the individuals studied were Cps(+), all of them were genotype A. Cps (+) birds were isolated and all confiscated birds received treatment with a specific antibiotic for Cps. The 90% of the pigeons seized died; while in July 2022, 5 parrots were released from that confiscation, in a reserve in the Santa Fe wooded wedge. A high prevalence of Cps genotype A infection was observed among the seized birds. Confirmations by molecular methods and genotyping of Cps on samples from birds or mammals have diagnostic and epidemiological relevance and allow the rapid application of specific treatment.
We consider that there are multiple causes of death of birds in addition to infection by Cps; optimizing the infrastructure of the Rescue Center would reduce the mortality of confiscated birds. The illegal trafficking of fauna continues to affect biodiversity due to the lack of knowledge in the general population and because this problem is not taken as a state policy. |

La psitacosis es una enfermedad zoonótica infecciosa aguda producida por Chlamydia psittaci (Cps), cuya denuncia es obligatoria para el médico y el veterinario. En humanos, la sospecha es generalmente baja, debido a que puede presentar diferente compromiso respiratorio y/o extrapulmonar. La comercialización de loros silvestres está prohibida en Argentina (Ley 22.421), sin embargo, cuando ocurre,son hacinadas en contenedores pequeños, en condiciones de maltrato animal. Se demostró en la provincia de Córdoba, que las aves libres no excretan Cps; mientras que sí lo pueden hacer, bajo condiciones de cautiverio. Se conocen 9 genotipos: A -F y E/B relacionados con aves, siendo el A, altamente virulento y M56/WC asociados con mamíferos. Objetivo: Detectar la presencia de Cps en pichones, recuperados del tráfico ilegal, en el Centro de Rescate e Interpretación de Fauna, La Esmeralda, diciembre 2021. Se obtuvieron muestras de 32 individuos, representativas de un total de 90 pichones. Se recolectaron hisopados oculares, orofaríngeos y cloacales de cada ave (pool de muestras) con y sin signología compatible con Cps. Se amplificó una porción del gen que codifica para 16SrRNA de género Chlamydia por PCR múltiple anidada (PCRMA). Posteriormente, se realizó otra PCR anidada que amplifica la región de la ompA para identificar especie Cps y las secuencias de productos de PCR analizados con programa MEGA 5. El 53.3% de los individuos estudiados resultó Cps(+), todas fueron genotipo A. Las aves Cps (+) fueron aisladas y todas las aves decomisadas recibieron tratamiento con antibiótico específico para Cps. El 90% de los pichones incautados falleció; mientras que en julio 2022, se lograron liberar 5 loros de ese decomiso, en una reserva de la cuña boscosa santafesina. Se observó alta prevalencia de infección por genotipo A de Cps entre las aves decomisadas. La confirmación por métodos moleculares y la genotipificación de Cps sobre muestras de aves o mamíferos presentan relevancia diagnóstica, epidemiológica y permite la rápida aplicación del tratamiento específico. Consideramos que son múltiples las causas de muerte de las aves además de la infección por Cps; optimizar la infraestructura del Centro de Rescate disminuiría la mortalidad de las aves decomisadas. El tráfico ilegal de fauna, sigue afectando la biodiversidad debido a la falta de conocimiento en la población general y a que dicha problemática no es tomada como política de estado.
