ABSTRACT The limited ability of molecular typing methods to differentiate Mycobacterium ulcerans strains from the same geographic areas, particularly at the local level, hampers our understanding of Buruli ulcer (BU) epidemiology and calls for the search for molecular epidemiological tools with higher discriminatory power. Moreover, the current available laboratory tests for BU diagnosis have various limitations, ranging from low diagnostic sensitivities to financial and technical constraints...
fflpaODDCTICW Cocoa Xllce many other plants of economic Importance, has a host of its own attendant pests among which lepidopterous caterpillars feature fairly prominently. Early reports on entomological pests in Wsst Africa (lamborn, 191U—1915j Patterson lyllti Peacock, 1913) almost invariably included one or other lepidopterous pest attacking some part of the cocoa tree or seedling. Recent reports* too, abound in information an the problem of Lepidoptera on cocoa e.g. Entwiatle (1960, 1...
Abstract Recently ethologists have drawn attention to "form-constant" or stereotyped, behaviour which may be tired off by specific environmental releasers or displayed "in vacuo" without stimulation. An important feature of form-constant behaviour is that it is exhibited by animals reared in complete isolation. Q3n.s has led to the conclusion that animals "have got" certain innate behaviour patterns just as they have got inherited morphological features. These innate patterns are characterist...
ABSTRACT Diarrhoea is among the six major diseases that causes death among children below age five worldwide. It is also a major cause of morbidity and mortality among children below age five in Ghana. Giardia lamblia is among the major enteropathogen causes of diarrhoea in Ghana. Most studies in Ghana on detecting G. lamblia use microscopy and enzyme linked immunosorbent assay. There is not much data on the molecular epidemiology of Giardiasis in Ghana. This study was conducted to determine ...
Abstract Interest in Cutex qu£nque fa so i atus Say ( = f atigans Wied) has been increasing with the growth of urban areas in the tropical zones of the world because this rjmosquito is an important vector of bancroftian filariasis. When increased urbanization is accompanied: by inadequate sewage treatment, conditions are ideal for proliferation of Cm qu'inquefa&ei a t u sm No other species of mosquito has benefitted rfiore from these acute sanitary problems than has C• qu£nquefaso'£atus�...
ABSTRACT The Black-winged Stilt (Himantopus himantopus) is one of few waterbird species that breeds in wetlands on the coast of Ghana. In recent times, its population has seen an increase on Ghana’s coast while other species are declining. The overall aim of the study was to investigate and document the breeding and foraging ecology of the Black winged Stilt in Ghana. The breeding ecology, diurnal time-activity budget and foraging behaviour of Black-winged Stilts were studied at the Densu D...
Abstract It has been shown in epidemiological studies that malaria may play a role in the pathogenesis o f endemic Burkitt’s Lymphoma (eBL). The contribution o f m alaria to the pathogenesis o f eBL is believed to be due to the imbalances in the immune regulation during malaria infection. Studies have shown a loss o f CTL function due to a shift o f the immune responses from T h l towards Th2 T-cell function during malaria infection. This study sought to investigate the phenotypes o f perip...
ABSTRACT A study to evaluate the genetic similarities and differences among 11 specimens of cichlids and four specimens of mudcatfishes obtained from Warri river
Abstract Dracunculiasis still remains as a disease o f public health importance in Ghana, especially in the Northern, Volta and Brong-Ahafo Regions, despite over a decade o f an Eradication Programme. In this study, attempts have been made to determine the problems associated with the eradication o f Guinea worm in the Northern Region o f Ghana, and suggestions provided to overcome them. Also investigated were the longitudinal anatomical variation of the parasite, the vector species and ...
ABSTRACT In a survey of children living in South Western Nigeria . plasma levels of a nti -MSP119 antibodies were not associated with patent parasitemia. Anti -MSP1 ,9 antibody titres correlated positively with age, indicating that development of antibodies to MSP1'9 may depend on long -term exposure to parasites.
ABSTRACT Indiscriminate disposal of electronic wastes (e-wastes) in Nigeria is on the increase. The release of hazardous substances from these wastes may have harmful consequences on the environment and public health. In Nigeria, there is dearth of information on environmental contamination and genotoxicity of e-wastes, and the mechanism of genetic damage. This study was designed to investigate the level of contaminants in soil, plant and well water; potential in vivo and in vitro cytogenoto...
ABSTRACT This study assessed the serum ferritin levels in plasma samples from children (4 – 74 months old) admitted for malaria at the Adeoyo Maternity Hospital (Beere) Ibadan, Oyo State, using a sandwich-ELISA. These values were compared with malaria parasitemia, MSP-1 antibody titre and packed cell volume values previously obtained through standard methods. Statistical analyses were carried out using SPSS, Excel and Epi-Calc software. Results showed that the serum ferritin level in the po...
Abstract Background: Rapid and accurate diagnosis is necessary for the management of schistosomiasis in endemic areas. Objective: To assess the burden of urogenital schistosomiasis and the diagnostic efficiency of morbidity indicators of the disease in an endemic rural community of Nigeria. Methods: A cross-sectional school-based study was conducted. Urine samples of 487 pupils were screened microscopically for S. haematobium and tested for haematuria and proteinuria using chemical reagent...
ABSTRACT Soil samples were randomly collected from 25 different observed and suspected human communal defecation locations within Ibadan. All the soil types encountered namely, sand, sandy loam, Sandy, clay loamy, and loamy sand enhanced hookworm larval propagation. The organic matter content showed a decrease with depth. The surface layer soil samples supported hookworm larval growth while the sub soil layer with the same amount of organic matter content as the surface soil layers showed a n...
ABSTRACT Malaria transmission is seasonal with higher transmission occurring in the rainy season. The burden of malaria falls mainly on children and causes anaemia and fever. Children of school going age are affected and this leads to absence from school. Blood samples were collected from children aged 10 days to 15 years in dry and rainy seasons. Parasite densities were determined by microscopy. Malaria prevalence was higher in the rainy season than in the dry season. In the dry season, 42.4...
