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 Background: MSP1 processing-inhibitory antibodies bind to epitopes on the 19 kDa C-terminal region of the Plasmodium falciparum merozoite surface protein 1 (MSP119), inhibiting erythrocyte invasion. Blocking antibodies also bind to this antigen but prevent inhibitory antibodies binding, allowing invasion to proceed. Recombinant MSP119 had been modified previously to allow inhibitory but not blocking antibodies to continue to bind. Immunization with these modified proteins, therefore,...
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 (...
combinations most times. The white crested hOl1lbill and the black and Maxwell's duikers were found to associate with the monkeys during feeding. No natural predators 10 monkeys were found. The agility of the monkeys coupled with various lliarm-response mechanisms seemed to prevent predators from getting close. Poaching by the surrounding communities seemed to be a problem in the Kakum National Park and this affected any initiation of monkey viewing as a tourist attraction. Viewing of monkeys...
Abstract Background: Effective control and management of severe malaria cases depends on a clear understanding of the local epidemiological factors and specific clinical manifestations of the disease in the different endemic regions. Objectives: To determine the prevalence of severe malaria and epidemiological factors that affect the development of malaria anaemia. Methods: A cross-sectional survey was carried out among children below 5 years of age, at the Adeoyo State Maternity Hospital,...
Abstract Worsened perinatal outcomes and increased rates (If maternal morbidity are consequences of co-infection of HI V and Plasmodium falciparum in pregnant-women. This study was designed to ascertain the proportion of co-infection of both diseases in pregnant mothers and babies born to HIV-infected mothers. A total of 149 pregnant mothers and 30 babies of HIV-infected mothers were engaged in a longitudinal study for III months in the endemic area of Saki and Ibadan. Only babies born to HI...
ABSTRACT An Enzyme Linked Immunosorbent Assay (ELISA), employing a recombinant peptide capture antigen (R32tet32) was used to detect antibodies against the circumsporozoite protein (CSP) of the malaria parasite, Plasmodium falciparum in 169 serum samples from 16 subjects from two villages, Afefu (FA) and Tobalogbo (TB), in Igbo-Ora Community of Oyo State, over a period of 12 months. The maximum and mean Ab response for FA was higher than for TB samples (0.511 AU±0.170, 0.124±0.045U and 0.2...
ABSTRACT Falciparum malaria and Type 2 diabetes (T2D) affect millions of people globally but the effect of the dual conditions on the cardiovascular health of the affected has not been investigated. To better understand this, a study was designed to evaluate the effect of Plasmodium falciparum malaria on levels of selected biomarkers of cardiovascular disease (CVD) risk in diabetics compared with non-diabetic controls by measuring anthropometric indices, blood pressure (Bp), fasting levels of...
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 Five feeds, designated A, B, C, D and E, were used in the culture of Oreochromis niloticus (L) to evaluate and compare their effects on growth performance, feed conversion ratio (FCR), fish production, survival rate and profitability in commercial tilapia farming in Ghana. Feed A contained only wheat bran and was used as the control; Feeds B, C and E were formulated from wheat bran, fishmeal, maize, palm oil and premix vitamins in varied proportions. Feed D was a commercial fish feed...
ABSTRACT Hypertension is a public health challenge due to its high prevalence, and is a major risk factor for cardiovascular diseases. Hypertension is a complex disease resulting from an interaction of genes and environmental factors. Inconsistent association between polymorphisms of the renin angiotensin aldosterone, the atrial natriuretic peptide systems and hypertension has been reported among various ethnic groups, but not for the Efiks and Ibibios in south-south Nigeria. This study was ...
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...
