ABSTRACT C ytological in vestigation s were made on some African Coreiods in the South-Eastern cocoa growing areas of Ghaia. Data is presented on karyotypes of the group. The now known karyotypes of the Coreoidea has been increased from 113 to 140 species by this study. E ffo rt has been ne.de to correlate information from this study with what exists in the litera tu re on morphological and cytotaxonomic studies rela tin g to the higher systematics cf the Coreoidea. Coreidae, Alydidae and Rho...
Abstract Schistosomiasis is the second most prevalent parasitic infection apart from malaria. Unlike the latter, whose prevalence tends to fluctuate with the rains in many areas of high endemicity for the year, schistosome infection prevalence may be usually high throughout the year in areas where the disease is endemic. Available WHO(1991) document indicates that the disease afflicts more than 200million people while 500-600million are considered to be at risk of infection in 76 countries. F...
SUMMARY Schistosoma haematobium antigens are the least studied amongst the three major human schistosomes (S. haematobium, S. mansoni and S. japonicum), mainly because of difficulty in maintaining the life cycle of this parasite in the laboratory. As a result, work on identification of potentially diagnostic and protective S. haematobium antigens lags behind. The work reported in this thesis was aimed at characterizing monoclonal antibodies recently produced against S. haematobium antigens s...
Abstract Schistosomiasis is a helminthic disease that affect many people all over the world causing illnesses that prevent people from farming and performing other activities, and at times gives rise to malignancies which are fatal. Between 1999 and 2004, some aspects of the epidemiology of schistosomiasis, were studied among 3190 inhabitants of Dogon-Karfe (the boundary with Jos North Local Government Area), Gigiring, Anglo-Jos Bukuru, Vom, Zawan, Mararaba-Jama’a and Farin-Lamba, all in J...
ABSTRACT Data on 2n-numbers of some fifty-five (55) species , belonging to six families of some Ghanaian shield bugs, collected in Southern Ghana, west Africa are presented. Microphotographs and tracings of karyotypes observed for each species are produced as figures. Histograms of chromosome numbers of the various families have been constructed and these results together with the existing information in literature, is analyzed and discussed. In all two hundred and seventeen (217) species of...
ABSTRACT Background: Malaria co-infection with schistosomiasis is known to modulate the immune response and thereby to potentially alter the pathophysiological and immunological profile of the diseases.
ABSTRACT Merozoite surface protein-119 (MSP-119) specific antibodies which include processing inhibitory, blocking and neutral antibodies have been identified in individuals exposed to Plasmodium falciparum. Here we intend to look at the effect of single andmultiple amino acid substitutions ofMSP-119 on the recognition by polyclonal antibodies from children living in Igbo-Ora, Nigeria. This would provide us with information on the possibility of eliciting mainly processing inhibitory antibodi...
ABSTRACT During studies on the epidemiology of malaria at a rural community, Igbo-Ora, Southwest Nigeria, genotyping of Plasmodium falciparum extracted from infective Anopheles gambiae s.l. was undertaken. Circumsporozoite (CSP) ELISA was used on crushes from head-thorax for DNA extraction and PCR amplification for the determination of P. falciparum genotypes on merozoite surface protein-I and 2 (MSP-I & 2). Of the 65 infective anophelines, P. falciparum genotypes were positively identified i...
ABSTRACTStudies were carried out under ambient laboratory conditions of 32 °C ± 2 and 74 - 87 % r.h. to determine the suitability of sorghum grain as a substrate that would support both the feeding and breeding of Prostephanus truncatus (Horn). Three sorghum varieties (Framida, Mankaraga and Naga-White) and one maize variety (Obatanpa) grown in Ghana were used in thestudy. Three forms of the substrates: Whole grain, Coarsely-ground grain and Grain flour were used for bioassays. The Fj proge...
ABSTRACT The monitoring of the current global strategy for the elimination of lymphatic filariasis (LF) can be confounded if other parasites indistinguishable from Wuchereria bancrofti also occur in endemic areas. An incidental examination of cattle blood revealed microfilariae that were morphologically similar to W. bancrofti. This study was therefore conducted to characterize these cattle filarial parasite. A total of 284 cattle from Somanya, Winneba and Axim were screened randomly for fila...
Studies on toxicological and sedative effects of Datura innoxia plant parts (leaf, seed, stem, pod and root) on Clarias gariepinus fingerlings were conducted under laboratory conditions using the static bioassays and continuous aeration. The aim was to develop an effective anaesthetic from an indigenous plant material that will be available at low cost to aquaculturists and which would be non-toxic to the fish and consumers. The active ingredients and their compositions in the plant par...
Abstract As an aid to the control o f the schistosome host snails, effective bioactive materials namely cassava, cocoyam, and sweet potato (Domeh, 1998), sugarcane and peels, all in their raw and processed states were tested in simulated natural environment experiments. The experiments were conducted using ‘biopots’ traps designed using a pot with few small windows created on the sides to allow easy diffusion o f test materials to reach the water body to attract the snails It was observe...
ABSTRACT Mole National Park is the largest and oldest national park in Ghana. With a large number of species of birds, mammals and reptiles, the number of tourists in Mole National Park keeps increasing and therefore creating room for human disturbance in diverse ways. Using the total area count method, this study established the species of waterbirds at Mole National Park and determined the seasonal variations in their diversity and abundance in four permanent wetlands from August 2015 to F...
ABSTRACT Data is presented on 2n~numbers of some forty- six (46) species of Tropical Reduviidae collected in Southern Ghana, West Africa. This information is combined with existing data and together analyzed and discussed. It was found that the roccgnised morphological plasticity of Reduviidae extends to the diploid numbers as well. However a level of cytological organization was found to exist within the family. Three autosomal-Chromosome groups: 20A, 24A and 23A are proposed. It has emerged...
ABSTRACT The transmission of zoonotic gastrointestinal parasites in cattle is dependent on the availability of intermediate hosts, poor sanitation and principally, the husbandry and management practices of cattle. The research work was aimed at studying cattle as reservoirs for parasitic zoonotic diseases in the Lower Manya Krobo District of southern Ghana. Microscopic examinations were done on stool samples to determine the prevalence and intensity of egg counts among cattle (N = 486) sampl...
