Malaria Vectors Composition, Abundance And Prevalence Of Malaria In Potentially High Endemic Area Of Morogoro Rural District, Eastern Tanzania

ABSTRACTThis dissertation was prepared based on “publishable manuscripts” format of the SokoineUniversity of Agriculture. The dissertation discusses the composition and seasonalabundance of malaria vector species and disease prevalence in potentially high endemicfoci in Morogoro region. Well targeted efforts that embrace area-specific situations, atleast in high malaria endemic foci, are needed to preserve realized health gains andachieve elimination. This is because malaria is increasing...

Effects Of Processing On Nutrient Composition, Shelf-Life And Protein-Bioavailability Of Anchovies Fish From Indian Ocean (Stolephorus Heterolobus

ABSTRACTThis study assessed changes in chemical components of the sun dried and hot smoked anchovies processed by traditional and improved methods. Except for the protein-bioavailability analysis which took place once during the fourth week, the samples of fish were assessed weekly. Nutrient composition, shelf-life and protein-bioavailability of processed anchovies were assessed using changes in proximate composition and specific minerals, biochemical indices and protein-digestibility, respec...

Uranium Uptake By Selected Food Groups And The Associated Health Effects To The Residents Of Bahi District In Tanzania

ABSTRACTAssessment of Uranium levels in selected food groups and products with the associated health effects to the residents of Bahi District was carried out. The objective was to come up with information on whether these food groups contain significant amounts of Uranium and if the community has been affected by uranium related diseases. This was done to bring the awareness to the vulnerable communities and Tanzanian Government in general on the environmental and health hazards posed by the...

Molecular Diversity Of Dna-B Component Of East African Cassava Mosaic Viruses In Tanzania

ABSTRACTBegomoviruses are whitefly-transmitted viruses belonging to the family Geminiviridae presenting most devastating threat to food security. This study was initiated to asses cassava mosaic disease (CMD) severity and genetic diversity of DNA-B component of East African cassava mosaic viruses (CMD) that infect cassava plants from main cassava growing regions in Tanzania. The study involved field survey, rolling cycle amplification (RCA) followed by next generation sequencing (NGS). The sy...

EFFECT OF VARIETIES AND DRYING METHODS ON NUTRIENT CONTENT AND SENSORY ACCEPTABILITY OF PROCCESSED PRODUCTS FROM “Mamung’unya” (Benincasa hispida)

ABSTRACT“Mamung’unya” (Benincasa hispida) is a seasonal fruit widely grown in Dodoma region. To distribute its availability throughout the year, there is a need to test different drying methods for preservation. The present study was carried out to assess the effect of drying methods on nutrient content and sensory acceptability of processed products from selected Benincasa hispida varieties available in Dodoma region. A total of 120 farmers were interviewed using a structured questionn...

Genetic And Antigenic Characterization Of Foot And Mouth Disease Virus Strains Isolated In 2011 And 2015 In Ngamiland, Botswana

ABSTRACTFoot-and-mouth disease (FMD) is a highly contagious disease of cloven hooved animals that continues to occur in Ngamiland District of Botswana although stringent disease control measures have been put in place. This may be due to irrelevance of currently used vaccine strains. In the present study, genetic and antigenic characteristics of SAT2 viruses isolated from outbreaks which occurred in 2011 and 2015 in Ngamiland districtwere examinedin order to determine any mutational changes o...

Investigation On Effectiveness Of Natural (Cactus Powder) And Synthetic(Grafted Potato Starch) Materials As Adsorbents For Hardwater Treatment

ABSTRACT This study was conducted to investigate the effectiveness of natural and synthetic materials as adsorbents for hard water treatment by using EDTA titrimetric method. Natural adsorbent prepared from cactus and synthetic adsorbent prepared by grafting potato starch and the study conducted on water samples collected from Nzuguni, Ng’ohong’hona, Kisasa and Swaswa in Dodoma municipality. The results revealed that the concentration of hardness decreased as the dose of (Cactus Mate...

Development And Assessment Of Nutritional Composition, Sensory Profile And Consumer Acceptability Of Jackfruit Seed Flour Buns From Locally Grown Jackfruit

ABSTRACTThe purpose of this study was to develop buns (Mandazi) based on wheat and jackfruit seeds flour and assess their chemical composition, sensory profile and consumer acceptability. Samples of jackfruit seeds were obtained from Tanga, Morogoro, Coast region and Zanzibar. Seeds were sorted, washed, pre-dried, seed coat peeled, sliced, dried and milled to flour. The developed jackfruit seed j flour from each location was blended with wheat flour at different levels of substitution (10%, 2...

Knowledge, attitude, practices and factors affecting fruit and vegetable consumption in adolescents (GOKWE SOUTH DISTRICT)

An ICT based framework for the enhancement of information sharing and collaboration in Zimbabwe’s tourism sector

ABSTRACTInnovations in ICT continue to transform business processes in ways never imagined before. When organisations take full utility of available technologies, business processes become more efficient while service delivery improves. Ultimately this bridges gaps between inter organisational relationships by making information sharing easier and more secure. This is crucial in the tourism sector where information is the lifeblood of the sector. The study sought to develop an ICT based frame...

Characterization And Thermostabilization Of Avibacterium Paragallinarum Candidate Strains With Potential Use As Candidate Vaccine Strains In Tanzania

ABSTRACTThis study was conducted to isolate, characterize, thermostabilize and develop an easier and cheap technique for preparation of inactivated and live vaccines against Infectious coryza (IC). Fifty six (56) samples were collected from chicken. Fourty eight percent (27) isolates had phenotypic characteristics suggestive of both pathogenic and non pathogenic Avibacterium species. Fifty nine percent (16) of 27 isolates were catalase negative, oxidase positive and NAD dependent. Moreover, t...

Comparative Study On The Effectiveness Of Sodium Metabisuphite, Acetic Acid And Lemon Juice In Preservation Of Dried Mangoes And Tomatoes

ABSTRACTMango and tomato are widely grown in the World. The present study was carried out to compare the effectiveness of three preservatives in retaining their quality attributes of mango and tomato and substituting the use of sodium metabisulphite with either the lemon juice or acetic acid. The three preservatives were sodium metabisulphite (0.1%), acetic acid (0.5%) and lemon juice (0.5v/v) studied at the respective level in bracket. Mango and tomato slices were dried in the walk - in sola...
