molecular epidemiology of chicken anemia virus in nigeria.between february 2002 and may 2004, chicken anemia virus (cav) was detected by pcr in organ samples from 14 flocks of poultry farms in lagos, ogun and oyo states in southwestern nigeria. the farms reported low (<5%) to high mortalities (up to 100%) with various lesions at necropsy. the complete vp1 gene of 30 of these positive strains was sequenced. strains that diverged by up to 4.4% on a nucleotide level differed only by up to 2.5% at the amino acid level (7 aa) as a result of clustered silent ...200616096706
further evidence for very virulent infectious bursal disease virus in vaccinated chickens in nigeria.reverse transcription polymerase chain reaction (rt-pcr) and partial sequencing of the vp2 hypervariable region was performed on clinical samples from two infectious bursal disease (ibd) outbreaks in plateau state, nigeria. ibd virus rna was detected in all four bursa of fabricius samples. nucleotide sequencing and analysis of the four samples revealed high similarity to previous ibdv sequences from northern and southern nigeria. the deduced amino acid sequences were compared to reference ibdv s ...201526149517
