Extent And Challenges Of Implementation Of Asei-Pdsi Approach In Teaching Of Science In Primary Schools In Emuhaya Sub-County, Vihiga County, Kenya

ABSTRACTActivity, Student, Experiment, Improvisation (ASEI) and Plan, Do, See, Improve (PDSI) is a pedagogical strategy advocated by Strengthening of Mathematics and Science Education (SMASE) program since 2010 to refocus the pedagogical practice of mathematics and science teachers and enhance learner achievement. During the life of SMASE, Sabatia, Vihiga, Kisumu West and Gem Sub-Counties neighboring Emuhaya consistently improved in science (ranging between 55-60%), unlike Emuhaya where perfo...

Studies On Microbial Spoilage

AbstractPour microorganisms were isolated from rotted onion bulbs, purple variety, purchased from markets in the Lagos State of Nigeria. Three of them were pathogenic they produced soft rot when wound-inoculated into healthy onion bulbs. The microorganisms were identified as Pseudomonas cepacia Buckholder, Candida utilis (Henneberg) Lodder and Kreger-Van Rig and Pseudomonas fluorescens Migula; the last being the most pathogenic of the three.A study of the effect of infection 10 of the nu...

Microbiological Studies Of Shrimp Spoilage

ABSTRACTBacterial counts of samples of freshly caught shrimp3, Penaeus duorarum and of see water from Nigeria, were carried out for a period of ton months, from April 1975 to January 1976. A monthly variation in the size of the bacterial populations of shrimps and son water was observed. Gram-positive bacteria were generally more abundantly isolated than Gram-negative bacteria from shrimps and 998 water. Coryneforns predominated the isolates. Next in abundance were micrococci, followed b...

Heavy Metal Contamination Of Ologe Lagoon, Nigeria And Biomarkers Of Oxidative Stress In Pachymelania Aurita

ABSTRACT The physico-chemical characterization, macrobenthic invertebrates and biomarkers of oxidative stress as indicators of heavy metal (Cu, Fe, Pb, Mn and Zn) contamination in Ologe Lagoon, Nigeria were investigated from January, 2007 - December, 2008. Biomarkers of oxidative stress [Catalase (CAT), Glutathione S- transferase (GST), Superoxide Dismutase (SOD), Reduced Glutathione (GSH) and Malondialdehyde (MDA)] activities were evaluated in Pachymelania aurita exposed to sublethal ...

Changes In The Seasonal Activity Of Bats Occuring In The Kunene Region, Namibia: Influence Of Environmental Factors

ABSTRACTThe Kunene region is an arid region with extreme environmental conditions. Understanding how environmental conditions affect bat activity, number and distribution is important for assessing activity and abundance. Monthly bat activity and the effect of environmental factors (temperatures, moon phase) on bat activity were recorded to elucidate factors influencing the distribution of bats. Wildlife Acoustic SM2 detectors were used to detect the bat activity from three sites, altitudinal...

Molecular Screening Of Potential Bat-Borne Hantaviruses And Determination Of Species Richness And Composition Of Bats In Selected Habitats Within The Woodland And Savanna Biomes In Namibia

ABSTRACTBats are present and they play unique ecological roles in various habitats in Namibia. Yet the patterns of species richness and composition of bats associated with these habitats within different biomes in Namibia still remain unknown. Bats are also important carrier hosts and transmitters of zoonotic viruses of public health significance including old and emerging hantaviruses. The burden of hantavirus disease is globally well-documented but this remains unknown and unrecognised in m...

Dust Bathing Behaviours Of Elephants, Zebras And Wildebeest And The Potential Risk Of Inhalational Anthrax In Etosha National Park

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 ant...

Schistosome Specific Antibodies in Individuals Co-Infected with Malaria in Southwest Nigeria

.Abstract. A cross-sectional study design in two primary schools in Ibadan and Akure was used to determine the prevalence orurinary schistosomiasis, and the human humeral immune response to schistose antigens in individuals withmalaria co-infection. Urine samples were collected from 163 children, while 112 gave blood samples. Malariaparasitaemia was determined by microscopy after Giernsa staining and schistdsomiasis by centrifugation technique.Serum samples were analyzed for antibodies t...

Developmental Regulation of Genes Encoding Universal Stress Proteins in Schistosoma mansoni

Abstract: The draft nuclear genome sequence of the snail-transmitted, dimorphic, parasitic, platyhelminth Schistosoma mansoni revealedeight genes encoding proteins that contain the Universal Stress Protein (USP) domain. Schistosoma mansoni is a causative agent of humanschistosomiasis, a severe and debilitating Neglected Tropical Disease (NTD) of poverty, which is endemic in at least 76 countries. Theavailability of the genome sequences of Schistosoma species presents opportunities for bioinfo...

FUNCTIONAL CHARACTERIZATION OF PLASMODIUM FALCIPARUM CLAUDIN-LIKE APICOMPLEXAN MICRONEME PROTEIN (PfCLAMP) (Pf3D7_1030200)

ABSTRACTMalaria 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 ...

The Insect Taxa on Cashew Anacardium Occidentale L.) Plants During the Flowering and Fruiting Periods in the Northern Region, Ghana

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 c...
