| molecular characterisation of african swine fever viruses from nigeria (2003-2006) recovers multiple virus variants and reaffirms cvr epidemiological utility. | samples collected from wild and domestic suids in nigeria, over a 3-year period (2003-2006), were evaluated for african swine fever (asf) virus genome presence by targeting three discrete genome regions, namely the 478-bp c-terminal p72 gene region advocated for genotype assignment, a 780-bp region spanning the 5'-ends of the pb125r and pb646l (p72) genes and the hypervariable central variable region (cvr) encoded within the 9rl orf (pb602l). asf virus (asfv) presence was confirmed in 23 of the ... | 2010 | 20052526 |
| spatio-temporal dynamics of african swine fever outbreaks in nigeria, 2002-2007. | african swine fever (asf) was first introduced into nigeria through lagos state in 1997. the disease rapidly spread to ogun state in 1998 and extended to the niger delta (delta, rivers and akwa ibom states) in the same year. in 1998, kaduna, plateau and benue states all north of the country experienced asf for the first time. poor farm biosecurity, bad abattoir practices and extensive/free range pig farming systems led to extensive spread of the diseases to about 16 nigerian states excluding the ... | 2010 | 20659268 |
