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 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...
ABSTRACT In the absence of microscopic examination, the high prevalence of asymptomatic malaria infections and the non-specific symptoms of the disease make clinical diagnosis difficult in highly endemic areas. Data from daily medical records 0f 111 adult volunteers obtained in a 13-month longitudinal survey were analysed using Pearson's correlation to investigate the relationship between parasitaernia and clinical symptoms and to determine the predictive strength of various clinical symptoms...
ABSTRACT The life cycle, and morphometries studies of A. dispersus (Rusell), white flies were conducted in a screen house in the Department of Zoology, University of Ibadan, Ibadan. The study revealed that A. dispersus (Rusell) on cassava potted plants leaves, Manihot esculenta (Cranzt) (TMS 91934), have six stages, which include, egg first instar, second instar, third instar, pupa and adult. Trichoderma lignorum a fungal was identified as the cause of high mortality rate which occurred on t...
Abstract Background: The most common cause of anemia is a deficiency of iron; but it may also be caused by deficiencies of folates, vitamin B12 and protein. Some anemias are not caused by nutritional factors, but by congenital factors and parasitic diseases such as malaria. This study attempted to estimate the prevalence of anemia among pre-school and school- aged children in two rural areas of Odogbolu Local government area, and to determine whether its cause was nutritional or could be att...
ABSTRACT Researches have shown that dried cassava varieties are relatively susceptible to Prostephanus truncatus (Horn) infestation. Laboratory studies were conducted to determine weight loss and nutritional status of dried cassava chips (TME-7) and P. truncatus emergence rate over an infestation period of 8 weeks. TME-7 mean weight loss (±SD) rose to 11.30% ± 4.01 (22.67%) with P. truncatus mean emergence rate (± SD) of 18.50 ± 8.25; 16.33 ± 6.85 and 9.93 ± 3.30 for larvae, pupae and a...
Abstract Possible control of Oryzaephilus surinamensis infestation on date palm (Phoenix dactyliferai using oil palm inflorescence ash and hermetic storage technique combined with Oil Palm Inflorescence Ash (OPIA) treatment were conducted in the Entomology Laboratory, Department of Zoology, University of Ibadan, Oyo state, Nigeria. Relative efficacy of oil palm inflorescence ash at 0.625 g 125 g and 1.25 g 125 g and 3 bags layer hermetic storage technique combined with oil palm inflorescence...
Abstract The focus of this research work was on the hermetic control treatment against Prostephanus truncatus Horn, 1878 infestation on dried cassava chips, over an infestation period of 10 weeks in the store. The experimental set-up was done in three hermetic treatments, this include, single bag, double bags and triple bags treatment. Each treatment was replicated 15 times. The used bags were made up of polythene material, with 0.056 mm thickness and 360 mm x 600 mm in dimension. The bags w...
ABSTRACT A 1O-week cross-sectional study was carried out at the Adeoyo State Maternity Hospital(Beere, Ibadan), Southwestern Nigeria in order to determine (a) the prevalence of severe malaria, (b) identify the predominant clinical presentations that characterise the disease in children below 5 years and the pattern of antibody responses to MSP 119elicited in severe malaria complications. Three thousand, one hundred and thirty-one cases reported to the Out Patients' Department; of these, 372 (...
ABSTRACT Significant variations in vector biology within and between countries have been reported in malaria epidemiological studies1. It is now generally agreed that a clear understanding of the detailed epidemiology of the disease is a pre-requisite to effective malaria control in the African sub-region2. Anopheles gambiae complex (Diptera: Culicidae) is one of the most efficient vectors of Plasmodium falciparum in the African sub-region; it is a complex of sibling taxa3. Two of these sibli...
Abstract The aim of this study was to investigate the morphology of Macrotermes bellicosus present on some parts of the University of Ibadan and to determine the effect of the saliva of termites on the strength of termitarium. Termites were collected from 8 termitaria on Parry Road, University of Ibadan and characteristics morphometrics were measured using stage graticules (10mm) on Microscope. Amylase analysis was conducted to determine the activity of the saliva content in the termitarium ...
ABSTRACT Acid phosphatase (ACP) activity was demonstrated in blood stream form of Trypanosome brucei brucei harvested from infected Wister rats by Ion Exchange DEAE Cellulose 52 chromatography. Whole parasite extract (WPE) and Excretory Secretory Extract (ESE) were prepared and analyzed for acid phosphatase activity. A higher ACP activity (85.5 µmol/min) was recorded in WPE compared to ESE (36.8 µmol/min). ACP activity in ESE is suggestive of the presence of a cell rich enzyme. Phase separ...
