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

ABSTRACTEggs 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 Nov...

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

ABSTRACTA 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. Bacteria...

ABSTRACTThis study was carried out to estimate the prevalence and related risk factors of porcinecysticercosis (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 wasemployed. A total of 260 live pigs were tested serologically. Serum samples were testedfor the presence of circulating parasite antigen using a m...

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

ABSTRACTA 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 rev...

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

ABSTRACTFungi 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 studie...

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

ABSTRACTViruses 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 observati...

Semigroups Of Linear Operators And Application To Differential Equations

This work concerns one of the most important tools to solve well-posed problems in the theory of evolution equations (e.g diusion equation, wave equations, ...) and in the theory of stochastic process, namely the semigroups of linear operators with application to dierential equations.

Studies On Yersiniosis In Human And Selected Animal Populations In Jos And Its Environs

ABSTRACTYersinia enterocolitica and Yersinia pseudotuberculosis are important food and water borne pathogens that has recently emerged world wide. This study was aimed at characterizing the prevalence of Yersinia enterocolitica and Yersinia pseudotuberculosis in human and selected animal populations in Jos and its environment. Three thousand stool samples from human and selected animal species from 5 different locations in Jos and its environs were surveyed over a period of three years. Human...

Epidemological Studies on Some Microbial And Parasitic Infectious of Nomadic Fulani Herdsmen in Ebonyi State, Nigeria

Abstract Over the years, nomadic Fulani herdsmen have established different settlement camps outside the traditional villages of their indigenous host communities in Ebonyi State. With increasing concerns about the health condition of the nomads, this study was undertaken to investigate the prevalence and distribution of some microbial and parasitic infections amongst the spartially distributed population of the nomadic Fulani herdsmen in Ebonyi State. This investigation was carried out...

Spray Distribution In A Tree Crop

Mature apple trees were sprayed using a Knapsack mistblower fitted with 3 different nozzle systems, one of which provided an induced electrostatic charge on the spray droplets. Spray distribution was assessed by examining fluorescent tracer deposits on Kromekote cards which had been positioned in different parts of the tree canopy. Subsequently, bioassays with codling moth (neonate larvae) and formulations of cypermethrin examined the biological effect of deposits. Small uncharged drop...

STUDIES ON BOVINE COCCIDIA [APICOMPLEXIA: EIMERIIDAE] IN PARTS OF PLATEAU STATE, NIGERIA

A parasitological examination of 2,500 faecal samples of cattle was carried out in Plateau State, Nigeria, to determine prevalence, seasonal distribution and sources of various species of Eimeria in both sexes, age groups, breeds and husbandry systems. Effects of temperatures on sporulation of Eimeria oocysts and chemical analysis of the Eimeria oocysts were also determined. Out of 2500 samples examined, 1567 i.e 62.68% were positive for twelve species of Eimeria...

Trends and Policy Correlates of Agricultural Production and Agricultural Production Sustainability Outcomes in Ghana and Nigeria

ABSTRACTThis paper analysed policy correlates of agricultural production and agricultural production sustainability outcomes in Ghana and Nigeria. It underscores the influence of political systems and international development agendas as correlates of agricultural production and agricultural production sustainability outcomes. This is to the extent of providing evidence policy on agricultural production and agricultural production sustainability outcomes. Ghana and Nigeria have comparable...

HUMAN METAPNEUMOVIRUS AND RESPIRATORY SYNCYTIAL VIRUSES IN GHANAIAN CHILDREN BELOW FIVE YEARS WITH ACUTE LOWER RESPIRATORY TRACT INFECTIONS IN ACCRA, GHANA

ABSTRACT Acute lower respiratory tract infection (ALRTI) in children under five years is predominantly cause by Respiratory syncytial virus (RSV) but in recent times Human Metapneumovirus (HMPV) has also been implicated in ALRTI. In Ghana, the few studies on ALRTI have focused on the prevalence of RSV and the viral etiological agents causing acute bronchiolitis, bronchopneumonia and pneumonia. This cross sectional study sought to detect, characterize and genotype respiratory syncy...
