Introduction Swine flu is a human respiratory infection caused by an influenza strain that started in pigs. The World Health Organization uses the term "(H1N1) 2009 pandemic" when referring to the Swine flu event, and officially adopted the name "A(H1N1)pdm09" for the virus in 2010, after the conclusion of the pandemic. Swine flu was first recognized in the 1919 pandemic and still circulates as a seasonal flu virus. Swine flu is caused by the H1N1 virus strain, which started in pigs. The Apri...
Typhoid fever is a communicable disease transmitted by the bacteria Salmonella typhi, related to serotype paratyphi A, B and C. The disease is a significant health concern in most developing countries especially Cameroon. Objectives: The study aimed at assessing the risk factors associated to typhoid fever in children (0-18 years) attending the “Deo Gratias” hospital in Douala. Method: A hospital based cross sectional study from August to September 2018 was carried out in children aged 0-...
In most parts of Cameroon particularly the Menoua Division, common bean (Phaseolus vulgaris L.) is usually consumed immediately after harvest or after a few months of storage. Contamination of common bean by fungi usually occurs in the field and during storage. It is possible that the incidence of food contamination by fungi varies between field and storage. The study aimed at determining the incidence of common bean infection by fungi during harvest and during storage. Six common bean cultiv...
East Coast Fever is a disease of cattle which results in high animal mortality with corresponding economic losses to farmers and to the nation. The disease is caused by a protozoan agent whose vector is Rhipicephalus appendiculatus (Brown Ear Tick). The tick feeds dominantly inside the cattle ear. Studies have shown that the adults of R. appendiculatus exhibit „pull-push‟ effect that guides them to their preferred feeding site. This is linked to the presence of ear volatiles which attrac...
Soybean (Glycine max (L.) Merrill) is referred to as the golden crop of the future. There is a concern in Kenya on its production due to the fact that the country remains a net importer of this vital food to the tune of 100,000 tons annually yet the country has the potential to produce that capacity locally. The major impediments in local production are singled out as: Expensive farm inputs in form of fertilizers and use of inferior soybean varieties in terms of effective nodulation. The nodu...
Kenya is the eighth highest producer of common beans (Phaseolus vulgaris L.) worldwide with a production of 529,265 tons annually. Climbing beans are highly productive, and can produce yields 2 to 3 times higher than bush beans and is therefore a promising option to increase bean yields in Kenya. However, climbing bean production is greatly affected by the decline in soil fertility, particularly low nitrogen levels in the soil. Replenishment of soil nitrogen using effective rhizobia inoculant...
Highly active anti-retroviral therapy (HAART) has been known to cause hepatotoxicity despite its benefit to improve the morbidity and mortality associated with HIV infections. However, the impact of HAART on HIV subtypes, drug resistance mutations and cytokine profiles, is not yet fully elucidated especially in the Northwest Region (NWR) of Cameroon. Therefore, this study was carried out with aim of determining the effect of HIV-1 subtypes, drug resistance mutations, cytokine profiles and ris...
In recent years concerns over dwindling reserves of ground and surface water resources coupled with an overloaded or costly sewage treatment plants has generated much interest in the reuse or recycling of greywater. Greywater is untreated household wastewater which includes water from; showers, laundry, dishwashers and washing machines. Re-use of greywater offers several advantages that include a reduction in the water bill, reduced wastewater discharge, as well as reduction in the demand on ...
Limited access to safe drinking water and information on water quality in sparsely populated arid and semi-arid regions has contributed to frequent outbreaks of diarheal disease. There is therefore urgent need to determine the bacteriological and physico-chemical quality of water in various sources in these regions. This study was undertaken in order to determine water quality in Wamba Division of Samburu District and to asses the efficacy of plan extracts in purifying water. Bacteriolog...
ABSTRACT In Kenya, aquaculture continues to expand as a source of food production and livelihood in all the counties. Mortality of Nile Tilapia and African Catfish fingerlings constitute the biggest loss in extensive and intensive fish farms. The main objective of this study was to determine contamination by bacteria and fungi in Nile Tilapia and African Catfish fingerlings. The study was carried out from March 2014 to July 2014 in fish farms with different water sources, hatchery systems an...
ABSTRACT A study was carried out to determine the heavy metal concentrations in the wetlands of Lake Victoria basin and their effect on bacterial resistance to ten commonly used antibiotics. Water and sediment samples for heavy metal analysis and microbiological assays were randomly collected from sewage outfalls and points bordering heavy metal activity settlements. Heavy metal analysis was done using Flame Atomic Absorption Spectrometer (F-AAS). The microbiological assays targeted heterotr...
ABSTRACT Water is the most critical resource in the Samburu District of Northern Kenya. The region has one permanent river, the Uaso Ng’iro. Use pressure by man, domestic and wild animals is high in all water sources, which include dams, laggas, and dry river bed wells. The primary objective of this study was to investigate the bacteriological and physicchemical quality of water from these sources, so as to shed some light on the causes of perpetual diarrheal diseases and their likely resp...
ABSTRACT Passion fruit (Passiflora edulis Sims) is an important fruit crop in Kenya for both local and export market. Production of the crop is constrained by many diseases. Fusarium wilt caused by Fusarium oxysporum f. sp. passiflorae is one of the major disease of purple passion fruit. Yield losses due to wilt have been estimated up to 80 %. Farmers lack appropriate management strategies for the disease and the use of bio-control agents to manage the disease has not been explored. The objec...
ABSTRACT Cowpea is a multipurpose legume crop that serves as human food, livestock fodder, and income source and is widely produced in sub-Saharan Africa. Soil fertility and attack by insect pests and diseases are significant limitations to its production. Although farm inputs such as phosphate-rich fertilizers and pesticides can solve the mentioned constraints, they are costly for resource-poor farmers. This study aimed at determining the effect of arbuscular mycorrhizal fungi inoculation ...
ABSTRACT While food borne diseases remain an important public health problem worldwide, one of the most significant food safety hazards is associated with those from animals. Food borne infections and illnesses are a major international health problem with consequent economic reduction and deaths. Meat is considered the most important source of proteins consumed by humans, yet most perishable. For highly perishable foodstuffs such as fresh red meat, the threat of food poisoning is particularl...
