Physiological performance of heat stressed growing rabbits fed diets supplemented with vitamin anti-oxidants and bicarbonate buffers

The aim of the study was to evaluate the physiological performance of heat stressed growing rabbits fed diets supplemented with vitamin anti-oxidants and bicarbonate buffers. A total of thirty (30) growing rabbits (New Zealand White crosses) of two months old were used in this study. There were six (6) rabbits per treatment in a Completely Randomized Design (CRD). The treatment groups consisted of: control, sodium...

Efficacy of Sudanese isolates of entomopathogenic fungi against the Khapra beetle Trogoderma granarium (Everts) (Coleoptera: Dermestidae)

The current study evaluated the bio-control activity of Sudanese isolates of entomopathogenic-fungi against 3rd larval instars of Khapra beetle (Trogoderma granarium) (Everts) in Sudan and morphologically and molecularly characterized the virulent isolates. Fungi were isolated using Galleria-baiting method and tested against the larvae using immersion-technique at concentration of 1×107 conidia ml-1. Commercial...

Metabolic engineering of Neurospora crassa for increasing carotenoids synthesis

Carotenoids are essential nutrient compounds with numerous biological functions. Neurospora crassa is a model filamentous fungus with orange pigmentation which is attributed to the accumulation of carotenoids containing neurosporaxanthin (NX) and neutral carotenoids (NC). To enhance carotenoids synthesis in N. crassa, isoprene diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) were increased using the genes,...

Optimization of PCR protocol for ISSR marker based genetic diversity assessment of acid lime [Citrus aurantifolia (Christm.) Swingle] germplasm in Eastern Nepal

Acid lime [Citrus aurantifolia (Christm.) Swingle] is a valuable commercial fruit crop grown in Nepal's Terai to high hills which has high economic, cultural and medicinal importance. Due to low quality planting materials and poor orchard management, production and productivity of acid lime are extremely low in Nepal. The present study aimed at optimization of Inter-Simple Sequence Repeat (ISSR)-polymerase chain...

Molecular characterization of Escherichia co-resistance genes from chicken meat

Escherichia coli multi-resistance to a variety of antimicrobials is a result of gene mutation on plasmids, integrons and transposons. The aims of this work were to: (1) detect genotype and phenotype antibiotic resistance genes in E. coli, and (2) determine whole-genome sequencing to discover E. coli gene multi-drug resistance in chicken meat. Samples were gathered, processed, and analysed bacteriologically; thereafter...
