Development of a Highly Sensitive Screen for Influenza A in Guano and Its Application in the Search for Ancient RNA Preserved Under Antarctic Adelie Penguin Colonies

Abstract: We have developed a reverse transcriptase polymerase chain reaction (RT-PCR)-based assay to detect influenza A in guano samples as part of our program to investigate ancient viral RNA from under Antarctic Adelie penguin (Pygoscelis adeliae) colonies. Of five extraction protocols tested (RNeasy, GTC TRIZOL, GTC Silica, Rnaid, and AGPC), AGPC proved to be the most consistent and sensitive to low concentrations of influenza, but further purification with commercial viral nucleic acid spin filter system was still … Show more

“…They also found serological evidence in samples from giant petrels at Harmony Point (63º24'S, 56º59'E) on Nelson Island, South Shetland Islands. Attempts have also been made to detect influenza A virus in penguin guano, using sensitive RT-PCR, but without success (Briggs et al 2003). Hence, our study like the few earlier studies finds serologic indications of influenza A virus in Antarctic birds, but yet there is no successful isolation of the virus.…”

“…As far as we know, all attempts to detect AIV by using sensitive reverse transcription-polymerase chain reaction, and further isolation from cloacal samples from penguin guano, have been unsuccessful (Briggs et al . 2003, Wallensten et al . 2006, Chang et al .…”

“…1981), and since then, several surveys of AIV have been reported from seabirds in the region (Austin & Webster 1993, Briggs et al . 2003, Wallensten et al . 2006), showing serologic evidence but no isolation of AIV (Munster et al .…”

“…Mas é fundamental que outros estudos na área de vigilância epidemiológica de NDV sejam realizados continuamente e com maior freqüência, monitorando populações aviárias em geral e enfatizando a necessidade de se estudar as diferentes linhagens virais isoladas ao redor do mundo, avaliando a relação vírus-hospedeiro e sua importância na epidemiologia, para que no caso de um surto da doença, este seja detectado o mais precocemente possível, para que as medidas de contenção possam ser tomadas a tempo de evitar uma grande epidemia, que iria incidir de forma bastante negativa na economia do país. (Briggs, 2003).…”
