The full-length chicken interferon-gamma (CHIFN-gamma) gene was amplified by reverse transcription-PCR using total RNA extracted from the spleen cells of white Leghorn chicken, a local Chinese breeding species. A truncated CHIFN-gamma gene without the N-terminal signal peptide sequence was cloned into prokaryotic expression vector pET30a, resulting in a recombinant plasmid pET-30a-CHIFN-gamma. ...
Fifty-eight Compylobacter strains were isolated from children with diarrhoea at various health centres in Lagos and from healthy chicken. Twenty-nine strains of Campylobacter were isolated from humans, while the same number were isolated from chicken. The strains were biotyped using the modified Preston biotype scheme. The Preston biotyping results have been compared with the results of Penner ...

This research was conducted to evaluate the effect of bacteria on removal of phenanthrene and anthracene from polluted soils using chicken manure as an auxiliary substrate. Materials and Methods: First, uniformly-graded soils were transferred to the pilots, then...
