Abstract Tuberculosis (TB) disease is caused by acid-fast bacilli called Mycobacterium tuberculosis. The emergence of drug-resistant TB variants as well as co-infection with the Human Immunodeficiency Virus (HIV) have complicated treatment for TB. Kenya currently implements TB screening and HIV testing for all patients and their caretakers, regardless of their reason for visiting the hospitals. Drug resistance is tested in all HIV-positive TB suspects to guide the choice of drugs in cases of...

Search result: 10 articles reporting on 5 clinical trials after different follow-up periods were found. Clinical outcomes: The results indicate no difference in retention and anatomic form of restorations after 1 – 3 years. Marginal adaptation appears to be superior for etch-and-rinse systems after 1 – 2 years and no difference was found after 3 years. Marginal discoloration is significantly more observed for (1-step) self-etch systems. Post-operative sensitivity was the same for both ...
Abstract Background: Trypanosomosis is a major impediment to livestock farming in sub-Saharan Africa and limits the full potential of agricultural development in the 36 countries where it is endemic. In man, sleeping sickness is fatal if untreated and causes severe morbidity. This study was undertaken in western Kenya, an area that is endemic for both human and livestock trypanosomosis. While trypanosomosis in livestock is present at high levels of endemicity, sleeping sickness occurs at low...
Abstract: Intestinal parasitic infections are the major public health problems in many developing countries including Ethiopia. The study was conducted with an objective to determine the prevalence and intensity of intestinal parasite infections among school children enrolled in Ahimed Gurey Elementary School, Jigjiga town, Somali Region, eastern Ethiopia. A total of 422 (219 males and 203 females) school children within age range of 5-19 years were selected by stratified random sampling met...
ABSTRACT Background: Blood transfusion is a life-saving practice in medicine but serves as a major route for spreading infections. It is therefore necessary to adopt sensitive screening technologies to guarantee the safety of blood. In Ghana, most districts and regional blood bank laboratories are limited in resources and resort to the use of rapid kits; a method less sensitive and liable to errors compared to enzyme-linked immunosorbent assay as the gold standard. This study seeks to determi...
Abstract: Intestinal protozoan and helminthes parasite infections are the major public health problems in many developing countries including Ethiopia. The objective of the present study was to determine the prevalence of intestinal parasitic infections and their association with anthropometric measurements among school children in Yeshimebet Primary School of Harari Region, Ethiopia. The study was a school based cross sectional survey, involving 422 participants (241 males and 181 females, ...
Abstract: Alkaline proteases are one of the classes of protease enzymes which are extensively used in detergent and tanning industries. Currently, there is an increasing demand for biocatalysts from extreme environments that are important sources of microorganisms routinely used in novel industrial enzyme production. In this research attempts were made to isolate and screen for an alternative alkaline protease producing fungal species from abattoir and food wastes. Hence, fungal species were...
ABSTRACT Rotavirus is a common cause of diarrhea in children. This study was carried out to determine the prevalence of rotavirus antigen in children below five years presenting with diarrhea in Gombe State. Thirty (30) stool samples were analysed using ELISA KIT. Out of the total number of samples analyzed, a prevalence of 6.67% was recorded all of which are between the age group 7-12 months. A more comprehensive survey is recommended to depict true states of rotavirus as an etiology o...
ABSTRACT Soil-Transmitted Nematodes (STNs) are roundworms transmitted through faecally contaminated soil. Globally, major STNs include Ascaris lumbricoides, Trichuris trichiura and hookworm (Necator americanus and Ancylostoma duodenale). School going children are mostly affected by STN infections. STNs cause malnutrition, intellectual retardation and cognitive deficits. They are distributed worldwide, Kenya included and they are of public health importance. Kenya has embarked on mass dewormi...
Abstract: Plant parasitic nematodes (PPNs) develop through three major stages in their life cycle: hatching, infection, and reproduction. Interruption of any of these stages can affect their growth and survival. We used screenhouse pot experiments, laboratory in vitro hatching and mortality assays, and chemical analysis to test the hypothesis that the non-host Asteraceae plant vegetable black-jack (Bidens pilosa) suppresses infection of the PPN Meloidogyne incognita in two susceptible Solana...
ABSTRACT The Petroleum Industry has a huge potential for the pollution of the environment at every stage of its operation, hence the need to constantly fashion out new strategies for maintaining the sanctity of our environment. Fungi associated with diseased Irvingia gabonensis (Baill) seeds found in the open markets were suspected to possess the ability to degrade the hydrocarbon substances contained in these seeds. These fungi were isolated bimonthly from the diseased seeds of I.gabonensis...
Abstract: Xylose is an unusual nectar sugar found in the nectar of Protea and Faurea (Proteaceae). Since nectar composition is an important floral characteristic in plant strategies for ensuring reproductive success, the unexplained presence of xylose in Protea nectar prompted this study of the interaction between pollinators and Protea species. Among pollinators that visit Proteaflowers in the south-western Cape Floral Kingdom, South Africa, insects and birds show an aversion to, and are po...
ABSTRACT Background: Efficient infection prevention and control (IPC) practices are basic requirements for all health facilities to reduce the morbidity and mortality associated with microbial agents and hence excellent patient outcome. Adherence to IPC is important to reduce the transmission of nosocomial infections.
ABSTRACT HIV/AIDS is a debilitating disease associated with high mortality and morbidity globally. In Kenya, it is the major cause of mortality across all gender and age groups, in effect, putting a huge demand on the healthcare system and the economy. The HIV 1 positive population faces major challenges such as the drug resistance, severe hepatic coupled with immunological deficiencies and toxicity. The problems are aggravated by co-infection with blood borne diseases, varied responses to ...
