Monitoring of veterinary drug residues in chicken, swine and cattle was conducted in Peninsular Malaysia from 2010 to 2016. Tissue samples were collected from slaughterhouses and processing plants. A total of six groups of veterinary drugs were analysed in 8,708 samples using bioassay or immunoassay and LCMS method. The average violation rate was 3.4%, 2.5%, 1.9%, 0.8%, 1.6% and 2.7% for year 2010, 2011 and 2012, 2013, 2014, 2015 and 2016, respectively

Antiviral effect of crude aqueous extracts of Neem leaves and Neem bark (Azadirachta indica) belonging to the family Meliaceae againstvelogenic Newcastle Disease virus was studied. Maximum non- toxic dose and determination of antiviral activity by in vitro and in vivo virus inhibition assay was carried out using embryonated SPF chicken eggs and SPF chickens. Different concentration content of the aqueous neem extract from branches of neem tree storing at 4°C reacted against velogenic ND virus was conducted. Determination of antiviral activity by in vivo assay in SPF chickens was compared to the group of untreated with Neem extract.

Conventional methods of detecting Corynebacterium pseudotuberculosis, a bacterium that causes caseous lymphadenitis (CLA) in sheeps and goats focused on several serodiagnostic tests such as ELISA, Western blotting and various inhibition and precipitation techniques. This paper described a Surface Plasmon Resonance (SPR) protocol for the direct detection of polyclonal
antibodies against Corynebacterium pseudotuberculosis with immobilisation of the antigen on unmodified transducer surface. The lower limit of detection was determined to be 2 μg mL-1 of immobilised antigen (Ag). Sufficient binding interaction was monitored on unmodified transducer; and saturation of the binding interaction was observed at 80 μg mL-1 of interacted antibody.
