ABSTRACT Bacillus anthracis is a soil-borne bacterium and the causative agent of the disease anthrax which commonly infects herbivorous animals. The disease is transmitted via three routes of infection: ingestion, cutaneous or inhalation of spores. This study investigated the seasonality of dust bathing as a possible contributor to inhalational anthrax in zebra, blue wildebeest and African elephants, in relation to the seasonality of anthrax mortalities in Etosha National Park. Most anthrax ...
.Abstract. A cross-sectional study design in two primary schools in Ibadan and Akure was used to determine the prevalence or urinary schistosomiasis, and the human humeral immune response to schistose antigens in individuals with malaria co-infection. Urine samples were collected from 163 children, while 112 gave blood samples. Malaria parasitaemia was determined by microscopy after Giernsa staining and schistdsomiasis by centrifugation technique. Serum samples were analyzed for antibodies ...
Abstract: The draft nuclear genome sequence of the snail-transmitted, dimorphic, parasitic, platyhelminth Schistosoma mansoni revealed eight genes encoding proteins that contain the Universal Stress Protein (USP) domain. Schistosoma mansoni is a causative agent of human schistosomiasis, a severe and debilitating Neglected Tropical Disease (NTD) of poverty, which is endemic in at least 76 countries. The availability of the genome sequences of Schistosoma species presents opportunities for bioi...
ABSTRACT Malaria is still a public health burden. With the recent reports of artemisinin resistance in Plasmodium falciparum coupled with the low efficacy of the RTS, S vaccine currently under a WHO-recommended pilot malaria vaccine implementation programme (MVIP), there is the need to continue identifying new targets by functionally characterizing some of the ~60% of the parasite’s genes with unknown functions. This will foster the identification of viable vaccine and possible drug targets...
ABSTRACT There have been debates whether insects that visit cashew during the flowering and fruiting periods are the same. The main problem arises as whether the insects that visit the plant during the flowering are the same that visit during the fruiting period. Field survey was conducted in ten farms in the Northern Region from December 2014 to April 2015 to identify and assess insects taxa on cashew in farms close to natural forest and farms away from natural forest, during cashew floweri...
ABSTRACT The purpose of the study is to find out the extent to which teachers faithfully commit themselves to the fidelity approach to curriculum implementation in transacting the Core English curriculum.

The sample comprised 150 students and all the 31 teachers of English. The number of students selected from each sch...
ABSTRACT This study focuses on the effect of the use of instructional materials on students’ performance in Biology – A case study of Surulere Local Government Area, Lagos state. Inadequate and ineffective use of instructional materials by teachers has been identified as one of the reasons for poor performance of students in Biology in secondary schools. The study aimed at investigating the effect of the use of instructional materials on the teaching of the subject Biology. It also exam...
ABSTRACT This study investigated the effects of concept mapping on students’ achievement in Biology. The study was guided by three research questions and three hypotheses using pretest and posttest design. The population of the study was made up of ten thousand and forty five students (10,045) in Senior secondary school class two (2), in the (2015/2016) academic session in Aba Educational zone, Abia state. The sample consisted of 400 Biology students, comprising 210 students in the experi...
