ABSTRACT: Coronavirus, also known as COVID-19, is a new disease that has crippled almost every aspect of human activities today. Common symptoms of the virus include high fever (38oC and above), dry persistent cough, shortness of breath and sore throat. Recently, additional symptoms which include diarrhea, fever and headache have been reported in South Africa. Medicinal herbs have been in use since ancient times for the management of viral infections related to COVID-19. Nutrient deficiency h...
ABSTRACT This research based on examining the relationship between inflation and unemployment rates in Uganda from 1990 -2013 which was guided by three objectives that were establishing the IeeI of inflation rate in Uganda, determination of unemployment rate in Uganda and investigating the relationship between inflation unemployment rates in Uganda between 1 990-201 3. The stud based on quantitative research approach employing the correlation and regression designs. 1 he findings indicated th...
ABSTRACT The effect of combinations of superphosphate and Minjingu phosphate rock (a sparingly water-soluble fertiliser) in the percentage ratios of superphosphate to Minjingu phosphate rock of 10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20 and 90:10 was studied in a laboratory incubation experiment. Three acid soils from Rift Valley Province having contrasting chemical properties were used. The treatments consisted of three P sources (superphosphate, Minjingu phosphate rock and m...
ABSTRACT The use of chemical herbicide in the management of aquatic weeds does not only constitute environmental and health problem but its cost and its non-specific nature calls for the use of biological control agents. An investigation was conducted into the probable use of indigenous fungi as potential mycoherbicides for water hyacinth (Eichhornia crassipes) control. Trips were made to Badagry Creeks, Mile 2 and Lagos Lagoon in Lagos State and Ogun river in Isheri, Ogun state to collect sa...
ABSTRACT The study focused on the factors contributing to the spread of HIV/AIDS in Homabay Sub County. Homabay County as a whole was ranked the first with the highest number of new infections in 2014 and Homabay Sub County being ranked number 2 with the highest infections. The study investigated why it was ranked to be among the highest with infections. The study used a descriptive research design that was used to depict the characteristics of the participants. The study population was 60 an...
The primary focus of this thesis was to investigate the movement patterns of the South African West Coast rock lobster, Jasus lalandii, using a diverse range of techniques. These were (1) an examination of long-term data from an ongoing tag-recapture program, (2) observations on rock lobsters in a mesocosm aquarium, (3) surveys that monitored the seasonal fluxes in activities and abundance of rock lobsters in the field, (4) video recordings of movement behaviour in small aquaria and (5) acous...
ABSTRACT The melon fly, Zeugodacus cucurbitae (Coquillett), is a serious pest of cucurbits, tree fruits and related crops in most continents of the world, including Africa. To manage the pest, most farmers in sub-Saharan Africa rely on synthetic chemicals which have detrimental effects to the environment and the habitat. Excessive use of chemicals may also lead to development of pest resistance and Z. cucurbitae has reportedly shown the most increased resistance to the used insecticides. For ...

ABSTRACT The rock art of southern Africa, Zimbabwe included, depicts a variety of symbols and characters that portray humans, animals, ceremonies and motifs of a spiritual nature. A lot of explanations have been proposed as to the function and meaning of rock art in general with the most accepted explanations linking the art to shamanism. This hypothesis (shamanism) argues that rock art paintings were created by shamans depicting dreams or visions of an individual seeking medicine or particip...
ABSTRACT Infectious diseases account for approximately one-half of all deaths in tropical countries. In industrialized nations, despite the progress made in understanding of microbiology and their pathogenic control, incidences of epidemics due to drug resistant micro-organisms and the emergence of hitherto unknown disease causing microbes, pose enormous public health concerns. Thus, there is need to continue the search for appropriate drugs for anti-microbial treatment without much drawback...
ABSTRACT The Napier grass stunt (NGS) phytoplasma is a phloem limited bacterium that is transmitted by insect vector, Maiestas banda (Hemiptera: Cicadellidae). The phytoplasma causes NGS disease in Napier grass resulting into huge forage yield losses hence impacting negatively the economy of smallholder dairy farmers in East Africa. Phytoplasma infections causes massive changes in phloem physiology including the sieve elements which may lead to reduced rate of phloem mass flow that interfere...
ABSTRACT Leptospirosis is an emerging zoonotic infectious disease that affects humans and animals worldwide as it causes febrile illness in humans. The disease has been reported in a number of human-livestock-wildlife interfaces of Northern and Eastern Tanzania. Very little is known of many zoonotic disease conditions in the research naive areas of Western and Southern Tanzania. This study aimed at detecting the prevalence of Leptospira species among agro-pastoralists at the human-animal int...
Abstract The prevalence of Human Herpes Virus type 8 (HHV-8), Human Immunodeficiency virus (HIV), and syphilis is high in Sub- Saharan Africa. Studies on HHV-8 in Kenya are few and data on its coinfection with HIV and syphilis scanty. This crosssectional study among female sex workers (FSWs) in Malindi, Kenya, aimed to determine the prevalence of HHV-8, HIV, and syphilis mono/coinfections and identify associated risk factors. A total of 268 FSWs consented and were administered a structured q...
Abstract The study was conducted in the camel research center (CRC)( Shambat )to compare the effect of two hormonal protocols in ovulation induction in dromedary she- camel ( Camelus dromedarius ) during non breeding season. Number of eleven she – camels with varying age (6 – 17 years) and the average body weight from (250 – 350 kg ) and one male used for mating were selected for this experiment. The experimental animals were divided into three groups : group (A) control group ( N =3), ...
ABSTRACT Background: Surgical site infections (SSIs) are the most common healthcare-associated infections affecting surgical patients. Such infections are often caused by methicillin-susceptible as well as methicillin-resistant Staphylococcus aureus. Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to the entire class of beta-lactam antimicrobials; which are largely used in clinical medicine. Patients infected with MRSAs therefore have limited therapeutic options, and this ...
