Table 1 Results of qRRT-PCR testing for pH1N1 virus in oropharyngeal and cloacal swabs of experimental turkey hens inoculated intranasally, intracloacally, or intrauterine with A/Chile/3536/2009 (H1N1) virus.

From: Susceptibility of turkeys to pandemic-H1N1 virus by reproductive tract insemination

Previous studies have shown correlation between qRRT-PCR results and infectious titer of influenza A virus for oropharyngeal and cloacal swabs [15]. We report our qRRT-PCR data in relative equivalent units (REU) based on a standard curve for A/Chile/3536/2009 (H1N1) in mean chicken embryo infectious doses (EID50)
