Comparison of Decontamination Methods for Isolation of Mycobacterium Species from The Environment

ABSTRACT The environment harbours many bacterial species, some of which include non-tuberculous mycobacteria which have recently become important in public health. Isolation of mycobacteria from the environment has not been easy because of the presence of other fast growing bacteria and fungi. For isolation of mycobacteria from the environment, decontamination methods that minimize contamination but maximize recovery of mycobacteria are needed. This study sought to compare three decontaminat...

Extended Spectrum Beta-Lactamase in Clinical Isolates of Escherichia Coli and Klebsiella Pneumoniae from The Tamale Teaching Hospital

ABSTRACT BACKGROUND: Extended Spectrum Beta-Lactamase (ESBL) producing Escherichia coli and Klebsiella pneumoniae are pathogens of significant public health interest to which new antibiotics therapies are urgently needed. AIM: This study was designed to determine the prevalence of ESBLs in clinical isolates of E. coli and K. pneumoniae from patients attending the Tamale Teaching Hospital (TTH). METHODOLOGY: The study was conducted from April through June, 2015. A total of 140 isolates of E....

Antibody Responses to Variant Surface Antigens and Biomarkers of Endothelial Damage and Repair in The Development of Cerebral Malaria

ABSTRACT Background: The pathogenesis of cerebral malaria (CM) is still recognized as multifaceted, despite the plausible explanation provided by the high degree of sequestration of parasitized erythrocytes in major organs of the body. Postmortem studies have demonstrated the presence of hemorrhage, deposition of fibrin and clots in blood vessels of the body where sequestration has been observed. These findings support a potential association between sequestration, endothelial damage and re...

Isolation and Characterization of Antifungal Agents Produced by Wood Decaying Fungi from Ghana

ABSTRACT Human systemic fungal infections have increased in the past decade due to the dramatic increase in immunocompromised patients hence the emergence of resistant fungal strains. It is therefore necessary to discover new antifungal compounds with novel mode of action. This study was aimed at isolating and characterizing antifungal agents from wood decaying fungi (WDF). The growth conditions for maximum production of bioactive agents from WDF were first tested. It was observed that miner...

Comparative Studies on Permanent Prostate Brachytherapy: PrePlan and Real-Time Transrectal Ultrasound Guided Iodine-125 Seed Implants at Korle-Bu Teaching Hospital, Ghana

CHAPTER ONE INTRODUCTION 1.1 Background Brachytherapy is a term used to describe the short distance treatment of cancer with radiation from small, encapsulated radionuclide sources. This type of treatment is given by placing sources directly into or near the volume to be treated. The dose is then delivered continuously, either over a short period of time (temporary implants) or over the lifetime of the source to a complete decay (permanent implants). Most common brachytherapy sources emit ...

Factor Analysis of Customer Preference for Mobile Phone Network (A Case Study of Cape Coast Polytechnic)

ABSTRACT This research tries to determine the “hidden” factors which ultimately influence the choice of mobile phone network in Cape Coast Polytechnic (study area). Principal Component method of Factor analysis is used to achieve the set objectives. There are six mobile phone network providers (MTN, Vodafone, Tigo, Airtel, Globacom and Expresso) in Ghana. All these operators try to improve their marketing strategies in order to attract more customers or subscribers to increase their mark...

Integration Of Ground Magnetic And Frequency Domain Electromagnetic Data, A Case Study From Nkwanta And Asuogya In The Western Region

ABSTRACT Ground magnetics and electromagnetic datasets were processed to interpret the subsurface geology and structure of the southwest of Ghana within the Tarkwain and Volcanics in the central part of the Ashanti belt. The study was aimed at mapping lithology, delineating structural lineaments and their trends as well as the trend of mineralization in the study areas. The data processing steps involved enhancement filters such as reduction to the pole, analytical signal, the first horizont...

Tectonic Impact On Regional Structural Trends in Ultra Deep Water Cape Three Points

ABSTRACT A 3D seismic data merged with a regional 2D seismic data and well data acquired from Ghana National Petroleum Corporation were used to determine the tectonic impact on regional structural trend in the Ultra-Deep Water Cape Three Points. The Cape Three Point basin was fashioned from transform tectonic and has been severely influenced by the largest tectonic feature in the central Atlantic Ocean, the west-southwest – east-northeast (WSW-ENE) romanche fracture zone. The study area li...

Assessment of Radiation Dose to Patients During Single Photon Emission Computed Tomography (Spect) 99mtc-Sestamibi Myocardial Perfusion Imaging (Mpi) In Niamey- Niger.

ABSTRACT Radiation absorbed dose for patients undergoing myocardial perfusion has been calculated for technetium-99m Hexakis-2-methoxy-2-methylpropyl-isonitrile (99mTcSestamibi) at the Nuclear Medicine Department of Abdou Moumouni University. Thirty patients were scanned and image quantification was achieved using MedisoInterViewXP® software. An activity of370 MBq (10 mCi) of 99mTc-Sestamibi was administered for stress and 1110 MBq (30 mCi) for rest. A 256 x 1024 matrix size and a speed of ...

Exposure and Fate of Neonicotinoid Insecticides in Cocoa plantations in Ghana

Structure of thesis The results from the thesis have been presented in chapters based on various experiments conducted. These chapters are intended as manuscripts for submission to international peer reviewed journals. Chapter 1 gives a general background to the thesis and presents pertinent literature on the topics understudy. While literature may be replete on neonicotinoids and other topics discussed in this thesis, these topics cannot be exhaustively discussed. As such, the literature mo...

A Web -Based Loan Management System A Case Study of Pride Microfinance Ltd

ABSTRACT This study focused on designing a Web-Based Loan Management System (LMS), which would assist the microfinance institution (Pride Microfinance Limited) to keep records of its clients which can be accessed wherever and whenever needed. The LMS developed during the study, stores records in a web-database and also allows online updates of the web application. An investigation was carried out to establish how the existing system functions regarding the problems at hand in addition to the...
