“…Researchers have reported that nasal and conjunctival swab samples taken from animals with clinical symptoms are more valuable as diagnostic material. Baydar et al (2013) stated that the most valuable necropsy material for diagnostic purposes was different materials such as lymph nodes, spleen, lung, oral-nasal swab and blood, and they found that positivity rates for lymph nodes, nasal and oral swabs, blood, lung and spleen were 54.2%, 66.6%, 45%, 46.2% and 46.2% respectively. In the current study, materials such as nasal swab, lung, spleen and lymph nodes were used to diagnose PPR infection with RT-PCR.…”
