Detecção de Ornithobacterium rhinotracheale (ORT) por meio da reação em cadeia da polimerase (PCR)

Abstract: RESUMOOrnithobacterium rhinotracheale (ORT) é uma bactéria Gram negativa recentemente descrita que se encontra associada às doenças do trato respiratório em criações de aves comerciais e silvestres em vários países do mundo. No Brasil, foram detectados anticorpos em um pequeno número de frangos de corte e suas matrizes dos Estados de São Paulo e Minas Gerais. Como a bactéria é fastidiosa, a Reação em Cadeia da Polimerase (PCR) torna-se útil para sua detecção e identificação. O presente trabalho visou verificar… Show more

“…There are several molecular studies on wild birds transmitting respiratory diseases to poultry, representing the initial route of the disease [5,23]. Several ORT isolates have been identified from birds, including chicken, turkey, duck, goose, pigeon, quail, ostrich, seagull, partridge, and pheasant [14].…”

“…Respiratory diseases in poultry are mostly accompanied by heavy economic losses and increased mortality rates, medication costs, and condemnation rates due to aerosacculitis and decreases in egg production. These infections have been recognized in many countries worldwide [1][2][3][4] and are associated with several microorganisms, including viruses and bacteria, and influenced by climate changes [5].…”

“…The PCR procedure is considered a useful laboratory tool for the identification of suspected O. rhinotracheale isolates (van Empel and Hafez, 1999;Chansiripornchai et al, 2007;Hung and Alvarado, 2001;Gornatti Churria et al, 2011;, and also for diagnostic or investigation purposes (van Empel and Hafez, 1999;Canal et al, 2003b;Eroksuz et al, 2006;Tsai and Huang, 2006;Pyzik et al, 2007). The primers OR16S-F1 (5´-GAGAATTAATTTACGGATTAAG-3´), and OR16S-R1 (5´-TTCGCTTGGTCTCCGAAGAT-3´) have allowed the amplification of a 784 bp fragment on the 16S rRNA gene of O. rhinotracheale (van Empel and Hafez, 1999;Hafez, 2002;Hung and Alvarado, 2001;Canal et al, 2003;Eroksuz et al, 2006;Tsai and Huang, 2006;Chansiripornchai et al, 2007;Pyzik et al, 2007;Uriarte et al, 2009;Gornatti Churria et al, 2011;.…”

“…As doenças respiratórias que acometem as aves domésticas criadas comercialmente geram perdas econômicas pelo aumento da mortalidade, gastos com medicamentos, queda de postura, redução na qualidade e eclodibilidade dos ovos. Diferentes vírus e bacté-rias podem ser responsáveis por patologias no trato respirató-rio das aves, atuando isoladamente ou associadas a outros microrganismos (Glisson 1998, Minharro et al 2001, Canal et al 2003.…”
