PRODUCTION OF COMPOSITE YOGHURT FROM BLEND OF SOY MILK AND COW MILK USING MIXED LACTIC STARTER CULTURES ISOLATED FROM AQUARAPHA YOGHURT

ABSTRACTThe need to improve our vegetable protein consumption in order to reduce the incidence of protein deficiency diseases cannot be over-emphasized. This research was premised on evaluating the appropriate levels of substitution of cow milk with soya milk to produce composite yoghurt. Eight hundred (800) grams of soya bean seeds after sorting out foreign materials and washing were usedto produce 4.0 liters of soya milk (20% total solids). Cow milk (20% TS) was blended with soya milk in th...

Diffusivity Of Chloride And Sulphate Ions Into Mortar Cubes Made Using Ordinary Portland And Portland Pozzolana Cements

ABSTRACT Cement is subject to degradation by aggressive media found in the environment. Durability tests are therefore necessary for any cementitious material in a given aggressive environment. This study investigated chloride and sulphate diffusivity in mortar made from selected Kenyan cements. The test cements included three brands of Ordinary Portland Cements (OPC) and three brands of Portland Pozzolana Cements (PPC). The test cements were used to make mortar prisms at different water / ce...

Repellence Of Essential Oil Of Nigella Sativa L. Seeds Against Anopheles Gambiae And Identification Of The Active Blend

ABSTRACT Anopheles gambiae mosquitoes are vectors of malaria because of their ability to transmit Plasmodium falciparum parasites. The major impact of malaria is in sub-Saharan Africa where at least 90% of the deaths from malaria occur. In Kenya, malaria accounts for 30% of all outpatients and 19% of all admissions to health facilities. Malaria can also affect the quality of labour negatively and also can lead to low productivity through absenteeism. Anopheles gambiae is the vector associated...

The Spectrum Of Bacteria Causing Urinary Tract Infection Among Pregnant Women Attending Sabasaba Clinic And Their Susceptibility To Antimicrobial Agents

ABSTRACT Urinary tract infections (UTI) during pregnancy can lead to serious obstetric complications, poor maternal and perinatal outcomes. The purpose of this study was to determinethe prevalence of bacterial UTI in pregnant women in Morogoro municipality, Tanzania. This study was conducted at SabaSaba Health Centre from May 2014 to July 2014 involving 196 pregnant women. Mid stream of urine samples were obtained and analyzed by dipstick and processed for culture. Out of 196 pregnant women ...

Food Additives And Hygienic Status Of Flavoured Fruit Juices Manufactured In Dar Es Salaam, Tanzania

ABSTRACT  The purpose of this study was to assess the quality of juices manufactured and sold for immediate consumption in Dar es Salaam Municipalities, Tanzania. The assessments were based on identifying the levels of preservatives, hygienic practices in manufacturing industries and determine microbiological quality of the juices. High Performance Liquid Chromatographic (HPLC) method was modified and validated for determination of benzoic and sorbic acids, while direct titration method was ...

Epidemiological Study Of Infectious Bursal Disease Virus In Selected Districts Of The Copperbelt Province In Zambia

ABSTRACT Infectious bursal disease (IBD) is a highly contagious disease of young chickens between 3 and 6 weeks of age. It is caused by infectious bursal disease virus(IBDV) which occursworldwide affecting livelihoods of resource - compromised poor communities. In Zambia, there is scantily documented information on the epidemiology of IBD. In-depth knowledge on the epidemiology of IBD is needed for effective control measures. This study aimed at molecular detection of circulating IBDV strain...

Isolation, Identification And Antibiogram Of Salmonella Enterica From Chicken Eggs Collected From Selected Wards In Morogoro Municipality, Tanzania

ABSTRACT Eggs provide protein to human. However, consumption of contaminated eggs with pathogenic Salmonellae (Salmonella enterica) imposes negative impacts to human health causing salmonellosis. The present study aimed at isolation, identification and antibiogram testing of Salmonella enterica from chicken eggs in Morogoro Municipality. A total of 570 raw, boiled, cracked, clean, and faecal soaked chicken eggs (120 local and 450 exotic) were collected from selected areas and examined from No...

Bacterial Contaminants Of African Indigenous Leafy Vegetables And Their Antibiotics Sensitivity Characteristics: A Case Study Of Morogoro Municipality, Tanzania

ABSTRACT A study was conducted in Morogoro Municipality, Tanzania to investigate the bacterial load found on African indigenous leafy vegetables, their sources and their sensitivity to commonly used antibiotics. A total of 126 samples of fresh African indigenous leafy vegetables (amaranth, nightshade and sweet potato leaves), water used for irrigation from rivers and shallow wells and manure fertilised soils were collected at farm sites and market outlets for bacteriological analysis. Bacteri...

Prevalence And Related Risk Factors Of Porcine Cysticercosis And African Swine Fever In Selected Urban/Peri-Urban Areas Of Morogoro, Tanzania

ABSTRACT This study was carried out to estimate the prevalence and related risk factors of porcine cysticercosis (caused by Taenia solium) and African swine fever (ASF) in domestic pigs, and assesses the state of pork inspection in urban/peri-urban areas of Morogoro region, Tanzania, between November 2010 and January 2011. A two stage random sampling was employed. A total of 260 live pigs were tested serologically. Serum samples were tested for the presence of circulating parasite antigen usi...

Investigating The Perfomance Of Lateral Flow Devices In Diagnosis And Genetic Characterization Of Foot And Mouth Disease Virus In Tanzania

ABSTRACT A study on rapid detection and diagnosis of foot and mouth disease (FMD) field outbreaks was carried out in field settings using a Svanodip® foot and mouth disease virus (FMDV)- antigen (Ag) test lateral flow device (LFD) in Serengeti and Ngorongoro districts of Tanzania. Epithelial tissues from cattle (n=80) were collected from different villages and tested at penside using Svanodip® FMDV-antigen test to evaluate the sensitivity and specificity of LFDs relative to gold standard re...

Diversity And Biological Control Potential Of Haloalkaliphilic Fungi From Lake Magadi, Kenya

ABSTRACT Fungi are eukaryotic microorganisms that have simple multicellular or unicellular cell structures. They are distributed in terrestrial soils, forests, aquatic habitats and in extreme environments with high ambient salts, temperature, pH and pressure. Fungi from extreme environments are potential sources of novel biocatalysts for example antimicrobial agents that can help solve the rising cases of drug resistance. However, the diversity of fungi recovered and described from less studi...

Microbial Community Diversity And Structure Within Organic And Conventional Farming Systems In Central Highlands Of Kenya

ABSTRACT Microbial diversity and function in agro-ecosystems is influenced by various aspects linked to soil and agronomic practices for example, tillage, irrigation, crop rotation and application of organic and inorganic inputs. Farming systems practices may affect the dynamic interactions existing between soil, plant and microorganisms in different agricultural biomes. Due to limitations associated with conventional microbial cultivation strategies, only a fractional number of cultivable sp...

Occurence And Distribution Of Pathogenic Viruses And Fungi In Sweet Potato Varieties In Gweru

ABSTRACT Viruses and fungi are the major threat to sweet potato production because they reduce yield by up to 90% thereby threatening food security. A study was carried out to identify pathogenic viruses and fungi affecting sweet potato and to determine their distribution across varieties and sites in Gweru. A total of 28 samples belonging to five different sweet potato varieties were collected from nine sites in Gweru. Plants were screened for viruses using two methods namely direct observat...
