Molecular Characterization Of Foot-And-Mouth Disease Virus Recently Recovered In Zambezi Region, Namibia

ABSTRACT Foot-and-mouth disease (FMD) is a severe highly contagious viral disease of clovenhoofed animals that has significant economic impacts. FMD causes significant economic loss in Namibia in which the molecular epidemiology of FMD virus (FMDV) responsible for the outbreaks has not been consistently studied. The general objective of this study was to determine molecular characteristics of FMD viruses of 2019 outbreak in Zambezi region, Namibia. A total of 11 epithelial tissue samples...

FIELD PERSISTENCE OF S-METOLACHLOR AND PENDIMETHALIN IN MAIZE-BASED CROPPING SYSTEM AND IMPACT ON EARTHWORM ACTIVITIES IN OGBOMOSO, NIGERIA

Application of chemicals on weed has been an effective method of weed control. However, this is with problems of persistence and hazardous effects on non-target organisms like arthropods. Common herbicides used in maize fields in Ogbomoso include atrazine, primextra, Lasso/atrazine, diuron pendimethalin, and S-metolachlor. Information on S-metolachlor and Pendimethalin persistence under field situations is inadequate. Therefore, persistence of S-metolachlor and Pendimethal...

EVALUATION AND INHERITANCE OF SINGLE AND MULTIPLE RESISTANCE TO VIRAL DISEASES OF COWPEA (Vigna unguiculata (L.) Walp)

Cowpea (Vigna unguiculata (L.) Walp) is one of the most economically and nutritionally important indigenous African grain legumes. It is cultivated in the tropics and sub-tropical regions in Asia and Oceania, the Middle East, southern Europe, Africa, southern USA, and Central and Southern America (Singh et al., 2002). It is an annual crop believed to have originated in Africa (Padulosi and Ng, 1997). Cowpea is well adapted to the dry savanna in the West African sub-re...

INTERACTION OF Meloidogyne incognita WITH Botryodiplodia theobromae ON Manihot esculenta (CASSAVA) AND ITS BIOCONTROL

The Root-Knot Nematode (RKN), Meloidogyne incognita and fungus Botryodiplodia theobromae, are important pests that cause yield losses in cassava and other crops. Chemicals have been used to manage these pests but with undesirable side effects. Information on pathogenicity of M. incognita, its interaction with B. theobromae and its biocontrol in Nigeria is very little. Therefore, pathogenicity of M. incognita on cassava, its interaction with B. theobromae and managemen...

EFFICACY OF SELECTED BOTANICALS AND MICROBIAL AGENTS AS ECO-FRIENDLY PROTECTANTS AGAINST Fusarium verticillioides (Sacc.) NIRENBERG EAR-ROT DISEASE OF MAIZE, Zea mays L.

Maize (Zea mays L) is the third most important cereal crop in the tropics (CIMMYT, 2004). It is an important grain crop in the world due to its ability to produce economic yields under the marginal production conditions of low soil fertility and management (FAO, 2005). Total world production of maize in 2011 was estimated at 817,110,509 MT. Nigeria‘s share of the production is 9, 180, 270 MT (FAOSTAT, 2011). It is a food crop of economic significance and nutritional...

DEVELOPMENT OF A RAPID URINE-BASED DIPSTICK TEST FOR DIAGNOSIS OF MALARIA

SUMMARYBloodsmear microscopy is currently the gold standard and the principal test for confirmatory diagnosis of malaria. However, microscopy is labour-intensive and is limited by inadequate sensitivity and specificity. Apart from microscopy, rapid diagnostic tests (RDTs), which include the quantitative buffy coat test (QBC) and the immuno-chromatographic tests (ICTs) are alternative tests for confirmatory diagnosis of malaria. RDTs, particularly, ICTs are fast gaining momentum as...

Potentials of Moringa oleifera Seeds and Aluminium Sulphate as Coagulants for Treatment of Water Samples from Usuma River, Abuja

ABSTRACT The potentials of Moringa oleifera seeds and Aluminium Sulphate as coagulants for the treatment of water samples from Usuma River Abuja was carried out. The physicochemical parameters investigated were the Turbidity (in NTU), Total Dissolved Solids (in mg/l), Conductivity (in μS), and Salinity (in ppm). For the water treatment with Alum, the standard municipal water treatment dosing of 360 mg/l was used. For the treatment with the natura...
