Abstract

Nigeria with about 10 million pigs account for over 30% of pigs reared in Africa yet swine influenza virus is not well understood. However emergence of swine origin A (H1N1) pdm09 stimulated global attention on the importance of pigs in influenza ecology and public health. We investigated the sero-prevalence of swine influenza in intensive piggery complex in Lagos Nigeria. Sera were conveniently sampled from March to August 2012 at three slaughter slabs and screened by competitive ELISA for influenza A and haemagglutination inhibition test for pandemic H1, classical H1 and H3 subtypes of swine influenza viruses. Out of a total of 302 analysed sera, 89 (29.4%) were positive for influenza A as follows; 88 (29%), were pandemic H1, 1 (0.3%) sample was weakly positive for H3 while 23 (7.6%) was positive for both pandemic and classical H1 showing some cross reactivity and the predominance of pandemic H1.

Key words: Haemagglutination Inhibition antibody, Nigeria, Pandemic A (H1N1) pdm09, pigs
