“…Moreover, the NAI activity from the serum of H3N4-, H3N5- or H3N7-immunized mice showed no cross-inhibition against the H3N2 virus. This result was in agreement with several reports on the effect of NA on immune responses, in which no inter-NA subtype cross-reactive antibodies were detected (Avellaneda et al , 2010; Beato et al , 2007; Capua et al , 2003; Peeters et al , 2012; Wang et al , 2011). These results could be attributed to the low homology between NA protein subtypes.…”

“…Most studies showed that NS1based tests had low accuracy as a DIVA test, as was found in this present studies (Tumpey et al 2005;Dundon & Capua 2009;Avellaneda et al 2010). Other studies, however, indicated that NS1-based ELISA ispotentially useful as DIVA test (Birch-Machin et al 1997;Ozaki et al 2001;Tumpey et al 2005;Takeyama et al 2011;Wang et al 2011;Golchinfar et al 2014). In spite of that potential of NS1-based ELISA as DIVA test, the test had rather low specificity because some vaccinated animals were also seropositive although with low antibody titres.…”

“…Sebaliknya, hewan yang terinfeksi diharapkan membentuk antibodi terhadap NS1 karena pada permukaan sel yang di dalamnya virus bereplikasi terdapat protein NS1 dalam jumlah yang besar. Atas dasar tersebut, antibodi terhadap protein NS1 dapat dipakai sebagai marker pembedaan antara hewan yang seropositif karena infeksi dengan yang seropositif karena vaksinasi (Tumpey et al 2005;Wang et al 2011).…”

“…Sejumlah penelitian yang membandingkan akurasi neuraminidase heterologus dengan ELISA NS1 sebagai tes DIVA menyimpulkan bahwa DIVA berbasis neuraminidase heterologus jauh lebih akurat dibandingkan dengan DIVA berbasis protein NS1 (Avellaneda et al 2010a;Wang et al 2011). Hasil survei terhadap negara-negara anggota OIE yang menerapkan strategi DIVA mengungkapkan bahwa tidak ada satu negara pun yang menggunakan tes berbasis protein NS1 sebagai tes DIVA (Swayne et al 2011).…”
