It is the third leading cause of mortality due to parasitic infections worldwide, after malaria and schistosomiasis. It is estimated that about 500 million people are at risk of infection with amoebiasis yearly. In developed countries infection occurs among travelers, recent immigrants from endemic regions, homosexual males, immune-compromised persons and institutionalized individuals. In...

Evaluation Of Selected Medicinal Plant Extracts For Insecticidal Properties Against Phlebotomine Sand Flies (Diptera: Psychodidae)

ABSTRACT Phlebotomine sand flies are the vectors of Leishmania species, the causative agents of leishmaniases that are a global health problem and are usually endemic in developing countries affecting predominantly the poor in society. Complementally control measures through use of biodegradable, safe and species selective natural compounds are urgently needed. Plant based compounds are safe in most biosystems. Some synthetic chemical insecticides are toxic, expensive and discriminate use may...

Zoonotic Gastrointestinal Helminths And Hemoparasites Of Baboons In Tana River, Tsavo And Laikipia, Kenya

ABSTRACT Zoonotic pathogens are among the most important causes of ill health in humans all over the world. In Kenya, the encroachment of wildlife habitats has led to increased interaction between humans and non-human primates especially baboons hence potential for zoonoses transmission. However, a risk analysis for these zoonoses had not been undertaken in Kenya. The current study aimed to investigate hemoparasites and gastrointestinal parasites of olive baboons (Papio anubis) at the human�...

Prevalence Of Geohelminthiases And Its Effects On Growth And Cognitive Functions In Pupils In Kibera And Korogocho Slums, Nairobi County, Kenya

      ABSTRACT Geohelminthiases are infections caused by Ascaris lumbricoides, Ancylostoma duodenale, Necator americanus, Strongyloides stercoralis and Trichuris trichiura leading to oedema, iron-deficiency, protein-energy malnutrition, electrolyte derangement, endocrine upsets and cardio-vascular failure. Resulting sequelae lead to poor health, physical fitness and anaemia. Geohelminthiases is widespread in areas with poor sanitation but empirical data on prevalence and its effects ...

Species Composition And Infection Rates Of Mosquitoes And Sand Flies In Mrima Hill, Kwale County, Kenya

ABSTRACT Mrima hill in Kwale County, along the Kenyan coast, is known to have high natural background radiation caused mainly by 232 Thorium (Th). Currently, the area also has no proper sanitary disposal system and people use bushes as toilets. There are no fresh water bodies. Despite other parts of the coastal regions of Kenya having been studied for human disease vectors including mosquitoes and sandflies, no studies have been carried out in Mrima hill to establish the prevalence of these i...

Analysis Of Phytochemicals And Anti-Plasmodial Activities Of Extracts From Harrisonia Abyssinica, Leucas Calostachys And Rubia Cordifolia Against Plasmodium Falciparum

ABSTRACT Malaria is the commonest parasitic disease that continues to cause considerable number of deaths despite the fact that it is treatable and preventable. In 2016, nearly 3.2 billion persons were at risk of malaria and a total of 216 million cases occurred occasioning deaths of approximately 445 thousand people worldwide with majority of the affected being children below five years of age. These numbers are high for a disease which is treatable and preventable. Plasmodium falciparum, th...

Prevalence Of Plasmodium Infection And Anaemia In Primary School Children Following Universal Distribution Of Insecticide Treated Bed Nets In Kasipul, Homa-Bay County, Kenya

ABSTRACT Malaria is devastating diseases afflicting humans, in Kenya; the disease is endemic in areas around Lake Victoria and along the southern coast. Untreated malaria in school children, result in anaemia, reduced ability to concentrate and learn in school and if fallen sick may lead to school absenteeism. Insecticide treated nets (ITN) have been shown to provide significant protection against Plasmodium infection. Available data show that the overall prevalence of Plasmodium and anaemia...

Spatial And Temporal Distribution Of Aedes Mosquitoes, Dengue And Chikungunya Viruses And Their Phylogeny Along The Coastline Of Kenya

ABSTRACT There are arthropod-borne disease outbreaks as a result of pathogen influx including arboviruses which are transmitted by strains of Aedes species that occur periodically in varying spots in Kenya. However, there has been paucity of documented information on the epidemiology of Aedes mosquitoes involved in transmission of different strains of viruses. This cross sectional study determined spatial and temporal distribution of Aedes mosquitoes, Dengue and Chikungunya viruses, and...
