ABSTRACT Schistosomiasis remains endemic in Ghana, with Schistosoma mansoni and S. haematobium being the two dominant species of the schistosome parasites. In some parts of Africa, previous works indicated the occurrence of pairings between these two species, resulting in the production of non-viable eggs (parthenogenesis). In Ghana, although both species occur in sympatry, it is yet to be shown whether this can lead to hetero-specific pairing within the definitive host leading to consequent ...
Intestinal parasitic infections caused mainly by protozoa and helminths are most prevalent in tropical and subtropical regions of the world where adequate water and proper sanitation are lacking. Helminthiasis has been listed among the three most prevalent diseases in Tharaka-Nithi County. The residents are mainly small scale nonmechanized farmers hence there is frequent contact with the soil. Chronic parasitic infection among students negatively affects their health, nutrition, cognitive dev...
Most variable speed wind turbines have pitch angle control mechanisms and one of their objectives is to extract maximum power from available wind speed. By adjusting pitch angles of wind turbine. In this research the use of pitch angle control for wind turbine equipped with self-exited induction generators (SEIGs) and power electronic converters is presented. To extract the maximum available power from the wind, the wind turbine is controlled using pitch angle control based on power sign...
ABSTRACT The socioeconomic burden of pollen and fungi spores allergy are very high in terms of hospitalization, treatment, lethargy, poor concentration and behavioral changes which impact negatively on adults and children. The study of atmospheric pollen and fungal spores in the six geopolitical zones of Nigeria was carried out from June 2011 to May 2012. The aims of the study are to determine the seasonal prevalence of atmospheric pollen and fungal spores, examine the impacts of weather par...
Abstract A study was conducted in Kampala International University- Teaching Hospital accident and emergency department between July 2013 to October 2013 to assess the awareness and practises of infection prevention amongst health care workers at their work place. The specific objectives of this study were to assess the practices of the staff in emergency rooms on the standard protocols observed in infections prevention, to identify the roles played by the administration in infection control...
ABSTRACT The specific objective of this study was to evaluate the standard of cleanliness of intracavitory transducers by Sonographers in Enugu; the exposure to infectious diseases and the specific regulatory guidelines for infection control in ultrasound laboratory.The research was a non-experimental cross sectional study. The sample size was 46 sonographers. The primary source of data was questionnaire. The result shows that 43.48% of Sonographers clean their intracavitory ultrasound tran...
ABSTRACT The potential of alkaloids from Panicum maximum floret infected with the fungus Tilletia ayresii in the control of uterine contraction in Sprague-Dawley rats was investigated using bioassay guided fractionation technique. Disease incidence study revealed that smut disease was significantly higher in Ikorodu site (95.00%) when compared with Akoka site (69.00%) and Isolo site (72.00%). The height of disease incidence was between the months of August and November. Thirteen species of f...
SUMMARY Rats experimentally infected with about 10 CFU or more of Campylobacter jejuns were promptly colonized. Campylobacter jejuni was recovered from faecal cultures of infected rats for up to 17 weeks post infection. The infected rats did not succumb to diarrhoea throughout the experiment. Haemagglutination assay was used to detect adhesins of Campylobacter jejuni isolated locally. Five out of 15 (33 percent) of the strains tested agglutinated erythrocytes of human blood group A+ and guine...
ABSTRACT Background: Caesarean section (CS) is one of the most frequent surgical procedures performed on women worldwide. Post CS wound infection is a major cause of prolonged hospital stay, complicating 3% to 15% of CS procedures worldwide. Surgical site infections (SSI) are associated with a maternal mortality rate of up to 3%. With the continuous increase in the rate of CS procedures performed, it is expected that post CS infections will increase in parallel, hence its significance. A...
ABSTRACT Groundnut samples collected from commercial markets in South–Eastern Nigerian were examined for seed borne fungi organisms and their level of losses were quantified. Results obtained showed that only about 29% of groundnut seeds were without damage. This high rate of damage is a major factor in low viability of groundnut seeds in South – Eastern Nigeria. From the survey of groundnut seed cultivars, two cultivars: Spanish 205 (nwaerente) and Samnut 21 (Ngwongworo) were observe...
The ability of bacteria to genetically encode resistance genes that subvert the inhibitory impact of prospective antibiotics is known as antibiotic resistance. It can be acquired through horizontal gene mutation processes like conjugation, transformation, and transduction or it can arise intrinsically through spontaneous recombination and integration into the bacterial genome. The inactivation of the porin channel, the alteration of antibiotic targets, and the enzymatic neutralisation of anti...
ABSTRACT A total of eight soil samples were collected from different sites within FUOYE environment and were analyzed to determine the presence of antibiotic producing bacteria, fungi and actinomycete Using nutrient agar, sabauraud dextrose agar and glycerol yeast extract agar as culture media. Seven bacteria: Escherichia coli, Bacillus spp, Pseudomonas spp, Azomonas spp, Gluconobacter spp, Micrococcus spp, and Staphylococcus aureus; five fungi: Rhizopus spp, Mucor spp, Rhodotorula spp, ...

ABSTRACTA study was undertaken to determine typical concentration of airborne bacteria and fungi (microflora) in Enugu State University of Science and Technology (ESUT) in the tropical rainforest environment of Nigeria. Aerial sampling was conducted at various faculties and departments each day. The air samples were collected thrice daily. Concentrations of airborne microflora exceeded available local guidelines for classroom, lobby, library and offices, but not in the restricted ...
ABSTRACT Cryptosporidiosis and giardiasis are common infections in humans in Kenya and Cryptosporidiosis in particular is an opportunistic infection in HIV-infected individuals. Diarrhoeal disease caused by these parasites is a major public health problem particularly in countries with poor socioeconomic status. The study on Cryptosporidium species and Giardia lamblia was carried out in Siaya county referral hospital and was conducted to assess the prevalence and risk factors associated with ...
