Degradation of Polyamide-6 By Microbial Isolates from Solid Waste Dumpsites in Lagos State, Nigeria

ABSTRACT Polyamide-6 (also known as nylon-6) is one of the biodegradation-resistant synthetic polymers used in the manufacturing of commodity plastic materials. The environmental effects of the persistence of this material in landfill and on surface water bodies pose global problems that endanger public health. Knowledge of the microbial distribution and pattern of their interaction with these plastics will provide the biological resources and scientific basis for the development of...

Selection, Product Characteristics And Metabolite Spectrum Of A Common Starter Culture For Fufu And Usi Production

ABSTRACT Fermented cassava products like fufu and usi (edible starch) are important staple foods in many African homes. Natural fermentation time is usually long resulting in slower acidification process and inconsistent nutritional composition of products which could be overcome with the use of starter culture. However, most available starter cultures are used for single food fermentation and are uneconomical. This necessitates the development of a starter culture for multiple related ...

Evaluation Of HIV Testing Methods And Development Of HIV Testing Algorithms In Lagos, Nigeria

ABSTRACT The absence of regulatory control of HIV test kits in use, non-availability of HIV testing algorithm and absence of regular and constant evaluation programme for HIV testing kits stimulated the authors' curiosity to carry out both operational and experimental studies on the commercially available HIV test devices circulating in the Nigerian market. A scientific approach to address the setbacks in HIV testing methods contending with HIV serodiagnosis and surveillance, as well...

Enrichment And Molecular Characteristization Of Atrazine Degrading Actinomycetes Isolated From Polluted Nigerian Commercial Farmlands

ABSTRACT Microbes capable of degrading atrazine were isolated by traditional enrichment technique from composite soil samples collected from four agricultural farmlands with long history of atrazine use in Nigeria. The estimated atrazine degrading populations from Obasanjo, Ladipo Daniel, Agbowa - Ikosi and Itokin farms were 1.6 x 10* cfu/mg, 8.0 x 10^cfu/mg, 5.0 x 10* cfw/mg and 1.2 x 10 cfu/mg of the soil samples respectively. The soil sample from Obasanjo farm was selected for fur...

Epidemiology Of Foot And Mouth Disease, Brucellosis And Leptospirosis At The Livestockwildlife Interface Area In Maasai Mara, Kenya

ABSTRACTIntact ecosystems can regulate the transmission of infectious diseases by maintaining thediversity of species in equilibrium. However, human driven land use change is a major driverof environmental change and can affect the emergence and the transmission dynamics ofinfectious diseases. This study investigated how land use change, and hence the extent ofwildlife-livestock interactions affect the transmission dynamics of infectious diseases in theMaasai Mara ecosystem in Kenya, using fo...

Response Of Avocado (Persea Americana Mill.) Rootstocks To Soil Flooding And Inoculation With Phytophthora Cinnamomi

ABSTRACTAvocado plants (Persea americana Mill.) belongs to the family lauraceae. Avocado fruit has high amounts of fats and proteins, high dietary fibre, vitamins and potassium. It is known to be the most nutritious of all the fruits. The most devastating pathogen of avocado plants is a fungal species, Phytophthora cinnamomi which cause avocado root rot. The fungus is the most widely distributed of Phytophthora species. It affects growth and physiology of plants and even leading to death of p...

Degradation Of Some Petroleum Hydrocarbon Pollutants By Micro-Organism From Contaminated Tropical Soils

Background of StudyPetroleum is a major source of energy in the world and Nigeria is one of the major oil producing countries. Petroleum production and operations are often accompanied with serious ecological problems. Oil exploitation, exploration, transportation, consumption, attendant spills and disposals are some of the ways in which oil pollutants get into aquatic and soil environments. This has become a major concern to governments, individuals, environmental activists and the com...

Concurrent Intestinal Parasitoses With Cryposporidium Species Among patients With Gastrointestinal Disorder In Lagos, Nigeria

Abstract Cryptosporidium, a protozoan parasite that causes gastrointestinal illness, is transmitted by ingestion of oocysts excreted in human or animal stools. Cryptosporidiosis presents with severe diarrhoea in HIV/AIDS patients and self-limiting in immunocompetent individuals. The parasite is yet to receive sufficient public health attention in Nigeria. This study was undertaken to investigate association of Cryptosporidium oocysts with other intestinal parasites in patients with ...

Enumeration, Identification And Antagonistic Potential Of Selected Microbial Isolates From Sugarcane Variety Co 421 Rhizosphere Against Sporisorium Scitamineum In Kibos, Kisumu County, Kenya.

ABSTRACTSugarcane smut disease caused by a fungus Sporisorium scitamineum is a limiting factor to cane production in Kenya. It is threatening the sugar industry due to its effect on cane quality and yields. Sugarcane (Saccharum officinarum L.) is known to have microbial organisms associated with its rhizosphere with potential antagonistic activity against the fungus, however numerous studies on rhizosphere microbial diversity and their antagonistic activity against fungal plant pathogens have...

Fungal Tinea Capitis And Associated Risk Factors In School Going Children Aged 3-14 Years In Kakamega Central Sub- County

ABSTRACTTinea capitis (ring worm) is a superficial fungal infection of the scalp and hair of the head. According to World Health Organization (WHO), the prevalence rate of superficial mycotic infection worldwide has been found to be 20-25% and the infection presents a major public health problem in primary school-age children especially those from low and middle income countries like Kenya. Tinea capitis inflicts a lot of psychosocial trauma in children due to attached stigma, ulceration and ...

Biological And Serological Studies On Toxoplasma Gondii In Lagos State, Nigeria

ABSTRACT Sera from 775 persons in 10 age-groups, living in Lagos metropolis, were titrated for Toxoplasma antibodies, using the haemagglutination test. The overall percentage positive was 63.2%. The highest (78.4%) was found amongst the age group ranging from 36-40 years, whilst the lowest (48.2%) was recorded in the age group. 11-15 years. The risk of non-immune persons acquiring infection was calculated in the different age groups using Van Der Veen's equation. Venous blood samples...

Comparison Of Hepatitis B Virus Sero-Markers, Clinical Stages And Genotypes Between Hiv-1 Infected And Uninfected Injecting Substance Users In Mombasa City, Kenya

ABSTRACTGlobally, it is estimated that 1.2 million injecting substance users are HBV infected while 1.7 million live with HIV. Africa is home to about 1.02 million injecting substance users of whom 12.7% are HBV infected while 12.1% live with HIV. In Kenya, the population of injecting substance users is approximately 50,000 most of whom reside in Nairobi and Mombasa cities. Nairobi and Mombasa cities are home to about 23,000 and 27,000 injecting substance users, respectively. The prevalence o...

Microbial And Physicochemical Parameters Of River Kuywa Water In Bungoma County, Kenya
