In this study, the sensitized latex beads coated with purified recombinant outer membrane (OM)-leptospiral surface antigen (Lsa27) lipoprotein of pathogenic Leptospira was evaluated as a diagnostic antigen in latex agglutination test (LAT) for the detection of anti-leptospiral antibodies in the human sera. The prepared rLsa27 latex beads were evaluated with the confirmed microscopic agglutination test (MAT) reactive (at 150) Leptospira-specific positive (n = 42) and non-reactive negative (n = 80) sera from human cases suspected of leptospirosis with the history of pyrexia of unknown origin. The results revealed the relative diagnostic sensitivity of 90.48 % (confidence interval (CI) at 95 % 77.4-97.3 %) and diagnostic specificity of 91.35 % (CI at 95 % 82.8-96.4 %), witvel.Bombyx mori nucleopolyhedrovirus (BmNPV) is a serious pathogenic microorganism that causes tremendous loss to sericulture. Previous studies have found that some proteins of serine protease family in the digestive juice of B. mori larvae have anti-BmNPV activity. In our previous publication about proteome analysis of the digestive juice of B. mori larvae, the digestive enzyme trypsin, alkaline A (BmTA) was filtered as a differentially expressed protein possibly involved in BmNPV resistance. Here, the biological characteristics and anti-BmNPV functions of BmTA were comprehensively analysed. The cDNA sequence of BmTA had an ORF of 768 nucleotides encoding 255 amino acid residues. Domain architecture analysis showed that BmTA contained a signal peptide and a typical Tryp_SPc domain. Quantitative real-time PCR analysis showed that BmTA was highly expressed in the larval stages and specifically expressed in the midgut of
