Schistosoma haematobium and Plasmodium falciparum single and concomitant infections; any association with hematologic abnormalities?

Aim: To assess the association between single infection and co-infection status of the twoparasites with hematologic profiles in school children.Methods: A cross-sectional epidemiological survey was carried out on a total of 202 schoolchildren between ages 6-18 years (mean age 11.5 ± 2.6 years). Urine and blood sampleswere collected by standard methods for concurrent microscopic diagnosis of Schistosomahaematobium and Plasmodium falciparum infections respectively. The following hematologicp...

Vernonia amygdalina: A folkloric herb with anthelminthic properties

Vernonia amygdalina, a widely grown shrub plant in Africa is consumed as vegetable and has high medicinalvalue. It has gained wide application in the treatment and management of various diseases. Theleaves are useful components for herbal medicine constitution. The plant’s activities is a result of diversebioactive compounds isolated from the different parts of the plant. These metabolites have specificallybeen efficacious against parasites especially worms. The mechanisms of activities i...

Plasmodial Infection and Haematological Parameters in Febrile Patients in a Hospital in Oyo Town, South-western Nigeria

A cross-sectional study on Plasmodium infection was conducted among 158 febrile patients (65 malesand 93 females) reporting to Oyo State Hospital, Oyo, South-western Nigeria. Parasitological andhaematological examinations of the blood samples were conducted. An overall infection rate of 29.7%was observed with parasite densities ranging from 96 - 64680 asexual parasites/µL blood. Thepercentages of infected male and female individuals were 27.7 and 31.2%, respectively. The least(12.5%) and the...

Lymphatic Filariasis in Southwestern Nigerian Rural Communities: A Cross-sectional Survey of the Knowledge, Awareness, and Predisposing Factors

AbstractBACKGROUND Nigeria is the second most endemic country in the world for lymphatic filariasis, withcontrol efforts often hampered by poor community awareness and involvement in intervention strategies.OBJECTIVE The aim of this study was to assess the knowledge, perception, and psychosocial aspects of some residents in Nigerian rural communities about lymphatic filariasis in order to develop disease control and intervention strategies with active community involvement.METHODS A standar...

MOLECULAR CHARACTERISATION OF BULINUS SNAILS – INTERMEDIATE HOSTS OF SCHISTOSOMES IN OGUN STATE, SOUTH-WESTERN NIGERIA

Abstract: Freshwater snails of the genus Bulinus O. F. Müller, 1781 are intermediate hosts for schistosomes, trematode parasites which cause schistosomiasis. The genus includes closely related species complexes with restricted gene flow between populations of each taxon. Despite their importance as intermediate hosts, unambiguous identification of these snails remains challenging. We applied molecular approach to their identification to achieve a better understanding of the epidemiology of s...

Review on INSECTICIDAL, ANTIFEEDANT, AND REPELLENT PROPERTIES OF SODOM APPLE (Calotropis procera)

Calotropis procera contained many biological active chemical groups including, cardenolides, steroids, tannins, glycosides, phenols, terpenoids, sugars, flavonoids, alkaloids and saponins. Several parts of this plants such as leaves, stern, latex and roots  exerted many entomological effects on a number insects pest. which includes anti-feedants, repellent, adulticidal, ovicidal and larvicidal. The present review will highlight the chemical constituents and the potential effects of...

Taxonomic Composition, Abundance and Distribution of Phytoplankton in Ifewara Reservoir, Southwestern Nigeria

ABSTRACTThe taxonomic composition, abundance and distribution of phytoplankton in Ifewara Reservoir, Southwestern Nigeria was studied for four months (February to December, 2015). Four sampling stations (designated Stations 1-4) were established along the horizontal axis of the reservoir from inflow region to the dam site end. The stations were all sampled at the marginal sides (A and C) and open water B except for Station 1 which was only at the open water. At each station, net plankton samp...

Effect of Hibiscus sabdariffa Calyces Extract on Estrogen and Progesteron Level of Pregnant Albino Rats.

Abstract This study investigated the effects of Hibiscus sabdariffa on the reproductive hormone of wistar rats.  Twenty eight wistar rats weighing between 160 – 200kg were used.  They were divided randomly into four groups (A – D) with seven animals in each of the groups.  Group A served as the control for group B and received 2ml of distilled water while group B orally received 2ml Hibiscus sabdariffa extract for 21 days, pregnancy was induced previously in these grou...

THE EFFECTS OF THREE ORGANIC FERTILIZERS POULTRY DROPPINGS CATTLE DUNG AND PIG EXCRETA ON THE GROWTH OF FINGERLINGS OF Clarias gariepinus

This research work was carried out to determine the effects of three organic fertilizers namely: cattle dung, poultry droppings and pig excreta on the growth of fingerlings of clarias gariepinus. A total of 120 fingerlings of average length (15.3+2.10) cm and weight (34.2+8.73)g were used for the study. Table oc contentChapter one Chapter two Chapter threeChapter four Chapter fiveReferences 

Influence of soil transmission helminths infections on the nutritional status of school children in Akinyele local government area, Ibadan.

Soil transmitted helminths (STH) infections; Anaemia and malnutrition are major public health problem in school age children in developing countries of the world. This study was conducted on 125 school children of Ebenezer primary school and Community high school, Shasha in Akinyele local government area of Oyo state. This study was carried out to assess the current prevalence as well as the nutritional impacts of STH infections among these school children.A school based cross sectional study...

The use of Palm Oil to mitigate stress in the African Sharptooth Catfish (Clarias gariepinus) during Transportation

INTRODUCTIONPhysiological stress and physical injury are the primary contributing factors of fish disease and mortality in aquaculture. Stress is defined as physical or chemical factors that cause bodily reactions that may contribute to disease and death. He further observed that Fishes tend to produce mucus under stressful conditions; any stress causes chemical changes in mucus which decrease its effectiveness as a chemical barrier against invading organisms. Stress upsets the normal electro...
