Bacteriological Assessment of Polythene Packaged Sliced Watermelon Sold by the Street Vendors in Enugu

ABSTRACT  This research was conducted in Microbiology Laboratory of Godfrey Okoye University to determine the antimicrobial efficacy of aqueous, methanol, ethanol of Pisdium guajava and Citrus x sinensis on the pathogenic Streptococcus mutans and Candida albicans. The Dimethyl sulfoxide was used for dissolving the plant extracts. Pisdium guajava showed antimicrobial activity against C. albicans with the exception of methanol showing no zone of inhibition to any of the isolates. The a...

Everything You Need to Know About the Swine Flu Pandemic

IntroductionSwine 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 April 2...

Investigation of typhoid fever and their associated risk factors in children

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 0-18...

Assessing the incidence of common bean in Cameroon

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...

Culturing, Characterization And Identification Of Candidate Microorganisms In Cattle Ear, Responsible For Producing Volatile Constituents Attractive To The Brown Ear Tick

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 whi...

Effect Of Different Soil Fertility Amendments On The Nodulation And Yield Of Two Soybean Varieties

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. Th...

Symbiotic Efficiency And Diversity Of Native Rhizobia Isolated From Climbing Beans (Phaseolus Vulgaris L.) In Embu And Tharaka Nithi Counties, Kenya

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 in...

Evaluation Of Genetic Diversity, Drug Resistance Mutational And Cytokine Patterns On Hepatotoxicity Markers Among Hiv Patients In Northwest Region, Cameroon

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 an...

A Comparative Study Of The Physico- Chemical Properties And Bacterial Load Of Greywater In Estates In Homabay Town And Githurai Estate

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 dema...

Bacteriological And Physico-chemical Quality Of Water From Various Sources In Samburu District And Efficacy Of Selected Plant Products In Water Purification

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&nbs...

Microbial Contamination Of Nile Tilapia (Oreochromis Niloticus) And African Catfish (Clarias Gariepinus) Fingerlings Reared In Hatchery Tanks At Sagana, Jambo, And Mwea Fish Farms

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 syste...

Association Of Heavy Metal Tolerance With Multiple Antibiotic Resistance In Bacteria Isolated From Wetlands Of Lake Victoria Basin Kenya

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 het...

Physico-Chemical And Bacteriological Quality Of Water, And Antimicrobial Susceptibility Of Pathogenic Isolates From Selected Water Sources In Samburu South

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 ...

Efficacy Of Selected Fungicides And Bio-Control Agents In The Management Of Fusarium Wilt Of Passion Fruit

ABSTRACTPassion 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 object...
