Identifica las cepas circulantes del virus de la Bronquitis infecciosa aviar en pollos de engorde del departamento de Lima mediante pruebas moleculares. Se colectaron muestras de tráquea y tonsilas cecales de 880 pollos de engorde de 3 a 6 semanas de edad que presentaban signos clínicos respiratorios moderados a severos y a la necropsia lesiones compatibles con Bronquitis infecciosa aviar; procedentes de 176 granjas, desde el año 2005 al 2014. Mediante la prueba de aislamiento viral se identificaron 92 muestras por las lesiones severas en el embrión compatibles con el vBIA. Por pruebas moleculares de RT-PCR en punto final y RFLP hasta el año 2010 y PCR en tiempo real a partir del año 2011; se detectaron en total 78 cepas del vBIA; determinándose que en su mayoría corresponden al serotipo Massachusets, (72, 44.31%), y las restantes, al serotipo Connecticut (2, 1.13%) y otros serot...

In Peru there is clinical evidence of the Influenza A virus (VIA) and the presence of antibodies against the VIA in pigs, but there are no official reports of frequency in pig farms in the country. The aim of the study was to determine the frequency of antibodies against VIA in technical farms in Lima, Ica and Arequipa with a history of respiratory problems. Blood samples were obtained from eight age groups of pigs during 2020-2021. Antibodies against VIA were detected using a blocking ELISA test (IDEXX, USA). A total of 283 serum samples from Lima, 287 from Ica and 288 from Arequipa were processed. The overall frequency of antibodies against VIA was 24.9% (95% CI 22.0 – 27.8); while in Lima, Ica and Arequipa it was 33.2% (95% CI 27.8 - 39.0), 19.5% (95% CI 15.1 - 24.6) and 22.2% (95% CI 17.6 - 27.5), respectively. The logistic regression analysis showed that in the Lima region, the ag...

Twenty-one different avian species identified as possible reservoir of avian influenza virus in Lima Metropolitan Region, Peru, Pacific flyway, South America.

Status of samples tested positives by hemagglutination test followed by confirmation using rapid antigen and PCR tests for influenza A virus.
