Porcine circovirus (PCV) type2 was isolated using primary porcine kidney cells from lymph node of piglets with typical PMWS. The presence of the virus was identified by PCR using primers specific to PCV type2. The ORFs 1 and 2 were amplified by PCR using primers corresponding to the target genes of the PCV type 2. Cloned genes were inserted into the baculovirus expression vector and PCV recombinant proteins were expressed using baculovirus expression system. Recombinant protein expression was... -

To evaluate the estrogenic activities of several chemicals such as 17beta-estradiol (E2), rho-nonylphenol, bisphenol A, butylparaben, and combinations of these chemicals, we used recombinant yeasts containing the human estrogen receptor [Saccharomyces cerevisiae ER + LYS 8127]. We evaluated E2 was most active in the recombinant yeast assay, followed by rho-nonylphenol, bisphenol A, butylparaben. The combinations of some concentrations of 17-estradiol as a strong estrogen and bisphenol A or... -

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed... -
