Research ArticleOpen accessIn the keywordsAssessment of Immunogenicity of CP8, CLFA-FnBPB and CP8-CLFA-FnBPB AntigensXiuli Liu, Yongqing Hao, Shuyi Wang et al.To assess the effects of conjugating Capsular Polysaccharide (CP) with Clumping factor A (ClfA) and Fibronectin-Binding Proteins B (FnBPB) on the immunogenicity of the antigen, CP was isolated and purified from serotype 8 (CP8) Staphylococcus aureus from bovine mastitis dairy herds in Inner Mongolia and ClfA-FnBPB was produced with Escherichia coli encoding a fusion protein ClfA-FnBPB gene. The CP8-ClfA-FnBPB complete … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 3 · 30 Aug 2013 · 7,545 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAntimicrobial Activity Studies of Bactoriocin Produced by Lactobacilli Isolates from Carrot KanjiHarshada M. Sowani, Prakash ThoratProblem statement: In the present study, Staphylococcus aureus a causative agent of food poisoning is selected as a test organism to study the antimicrobial effect of bacteriocin. S. aureus produces number of exotoxins and enterotoxins which enters the body via contaminated food causing illness. Approach: In this case the use of antibiotics is one of the ways of treatment, but … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 2 Mar 2012 · 8,543 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAntibacterial Activity of β-Cyclodextrin and 2-Hydroxypropyl-β-Cyclodextrin Trimethoprim ComplexesHsien-Kuo Sun, Madhumathi Seshadri, Scott Lingard et al.Problem statement: Cyclodextrin complexation has previously been shown to improve the solubility and dissolution properties of trimethoprim; however, no report provides an account of the effect cyclodextrin complexation has on the antibacterial activity of this agent. Approach: β-cyclodextrin and 2-hydroxypropyl β-cyclodextrin inclusion complexes of trimethoprim were prepared and confirmed by differential scanning calorimetry and proton nuclear magnetic resonance. The in-vitro … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 14,801 accessesView PDFCite
