ABSTRACT Chlamydia trachomatis infections are the most common bacterial cause of sexually transmitted diseases (STDs) in the world. This study was to investigate the prevalence of Chlamydia trachomatis infection amongst students of Federal university Oye-Ekiti, Ekiti State, Nigeria. Urine samples were collected from ninety four participants and were screened using the microwell ELISA Chlamydia trachomatis kit - Swab/Urine . (Golden Bio Technologies Corp, USA). Out of 94 patients screened, 26...
ABSTRACT Alpha amylase enzyme (EC 3.2..1. 1) (a-1, 4 glucan-glucanohydrolase) is widely distributed in nature such as plants, animals and microorganisms. Production of extracellu Jar alpha-amylase from fungi was isolated from rhizosphere of Moringa oleifera. Three (3) fungi isolates were selected after serial dilution of the soil samples, four optimization parameters was employed to determine the enzyme activity and they include effect of inoculum size, pH, nitrogen source and surfactant·on...
.ABSTRACT The growing population concern about health has recently led to the development of natural antimicrobials to control diseases. Medicinal plants and spices are one of the most commonly used natural antimicrobial agents in food and have been used traditionally for thousands of years by many cultures for controlling common health. Zingiber ojjicinale has long been used as naturopathy due to their potential antimicrobial activity against different microbial pathogens. This study was co...
ABSTRACT Dengue Virus is the most prevalent arthropods borne viral infection in tropical and sub-tropical regions worldwide and they are transmitted by Aedes aegypti and Aedes albopictus. This experiment was conducted with the aim of detecting and establishing possible sylvatic transmission of Dengue Virus in mosquitoes caught in Oye Ekiti. Mosquito life traps were used to trap 200 Aedes mosquitoes which were then knocked down by the use of insecticides. RNA were extracted from the mosquitoe...
ABSTRACT S. aureus is an extraordinarily versatile pathogen, and it can cause a large spectrum of infections, from mild to severe and fatal. It is important in humans and also economically important when infecting animals, able to cause superficial lesions and systemic infections. The aim of this study is to detect Can, Ica, Hlg and SdrE virulent genes of Staphylococcus aureus associated with different types of infections among Sudanese in Khartoum State. The Samples were collected from dif...
ABSTRACT Sorghum is one of the major cereals malted for the brewing of beer. The conditions of transport and storage of this cereal predispose it to contamination by microbes thus affecting the quality of the end products. The contamination is usually controlled by treating the sorghum with chemicals, which however alter the chemical constituents of the sorghum. Therefore, the need to seek alternative functional methods of control of microbial contaminants becomes imperative. This study was ...
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 sustaina...
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 food ...
This study was done to detect the prevalence of oral Candidiasis among Sudanese cancer patients with different cancer types who received different cancer treatment in Khartoumoncology hospital which formerly was known as Radio and Isotopes Centre of Khartoum (al Zarra Hospital) which recently named Khartoum Oncology Hospital. .A hundred oral swabs were collected from the patients with different age groups ranging from 2 to 83 old, 66@ were males and 34@ were females.The study was carried ...
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 as deter...
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 further stud...
ABSTRACT Intact ecosystems can regulate the transmission of infectious diseases by maintaining the diversity of species in equilibrium. However, human driven land use change is a major driver of environmental change and can affect the emergence and the transmission dynamics of infectious diseases. This study investigated how land use change, and hence the extent of wildlife-livestock interactions affect the transmission dynamics of infectious diseases in the Maasai Mara ecosystem in Kenya, us...
ABSTRACT Avocado 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 ...
Background of Study Petroleum 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 communit...
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 gastrointe...
