Seroprevalence of CCPP, FMDV, BTV and BVDV among small ruminants in Tanzania : A minor field study with focus on differential diagnoses of peste des petits ruminants virus por Päärni, Malin

“…This degree project has been performed as a Minor Field Study (MFS) in Tanzania, investigating the seroprevalence in goats and sheep of three diseases causing similar signs as peste des petits ruminants virus (PPRV): foot and mouth disease (FMD), bluetongue (BT) and contagious caprine pleuropneumonia (CCPP), as well as bovine viral diarrhoea (BVD) and border disease (BDV) which is believed to affect an outbreak of PPR due to immunosuppression. …”

Application of near infrared reflectance spectroscopy in screening of fresh cassava (Manihot esculenta crantz) storage roots for provitamin A carotenoids por Alamu, Emmanuel Oladeji, Maziya-Dixon, B.B., Felde, T. zum, Kulakow, Peter A., Parkes, Elizabeth Y.

“…Also, significant (P ≤ 0.001) positive correlation (r = 0.52) exist between trans β-carotene predicted by NIRS and high-performance liquid chromatography reference. The developed NIRS calibration equations could be used to predict total carotenoids and trans β-carotene content of yellow root cassava and serve as rapid and cost-effective screening method for large cassava sample sets.…”
