ABSTRACT The consequence of intense permanent cultivation of land has been severe loss of soil nutrients through removal of harvested produce, removal of crop residue, leaching and gaseous losses. Experiments were designed to investigate the effect of soil amendment with cow manure, chicken manure and fertilizer on nodulation and nitrogen fixation in climbing beans (MAC 64) and soybeans (Gazelle). Isolation and characterization of isolates together with greenhouse experiments were carried out...
ABSTRACT Because of the prevalence of antibiotic resistant pathogenic bacteria, infectious diseases are becoming more difficult and expensive to treat. In Kenya, high levels of flouroquinone resistance of a bacterium, Neisseria gonorrhea have been widely reported. Antimicrobial resistance may be coded on plasmids, mutational events or on transposons. A growing body of evidence indicates that metal tolerance and antibiotic resistance are often found together in many clinical isolates and that ...
ABSTRACT Urinary tract infections (UTI) are bacterial infections encountered in the hospital and community and is preventable. It is among bacterial infection encountered with increasing antibiotic resistance to uropathogens, although there is availability of antibiotics. Despite the wide spread of antibiotics, it remains the common bacterial infections. Antibiotic susceptibility testing therefore provides information that allows clinicians to select the most appropriate antimicrobial drugs. ...
ABSTRACT Aflatoxin contamination of maize in Africa poses a major threat to food security and the health of many African people. In Kenya, aflatoxin contamination of maize is high due to the environmental, agricultural and socio-economic factors. Many studies have been conducted to understand the scope of the problem especially at pre-harvest level, but few of them have been concentrated to the post-harvest level. This research was carried out to gather scientific information on the fungi pop...
ABSTRACT Diarrheal diseases are the commonest manifestation of food poisoning, which are fatal. Knowledge, attitude and practice of food handlers influence the occurrence of food poisoning. Staphylococcus aureus is considered the third most important cause of food-borne diseases in the world after Salmonella species and C. perfringens. Antimicrobial resistance and enterotoxigenic properties of S. aureus in food of animal origin in many parts of Kenya are scanty. The aim of the study was to in...
ABSTRACT Urinary Tract infection (UTI) is a serious infection causing illness in infants and children. It represents one of the most common diseases encountered in medical practice today. Despite the widespread availability of antibiotics, it remains the most common bacterial infection. Antimicrobial susceptibility testing therefore provides information that allows physicians to select the most appropriate antimicrobial agents for treating these infections and give the most effective antibiot...
ABSTRACT Background: The pneumococcus is carried as a normal flora of the upper respiratory tract and carriage is the precursor for development of pneumococcal disease, and is also responsible for pneumococcal transmission from person-to-person. HIV positive children have about forty times greater risk of invasive pneumococcal disease compared to healthy children. In Africa, little is known about the pneumococcus in relation to people with HIV infection. Aim: The aim of the study was to inv...
ABSTRACT Background: Data on the transmission of hepatitis B virus (HBV) within correctional facilities is limited in Ghana, even though the prevalence suggests intra-prison transmission. Aim: This study determined the level of transmissibility, new infections, and intraprison transmission of HBV among inmates in Ghana Methodology: Immunoglobulin M antibodies to hepatitis B core antigen (anti-HBc IgM) and Hepatitis B e antigen (HBeAg) were determined for 323 archived plasma samples obtaine...
Aimed to this study was to study the antibacterial activity of the different concentrations of methanolic and aqueous extract of the medicinal plants A.nilotica sub spp nilotica and sub spp adansonii pods using agar dilution method. Hundred wound swabs were collected from patients with infected wounds who attended to Soba Teaching Hospital and Alban Gadeed Teaching Hospital during period from March to October 2015. From this study it was found that wound infection had high frequency in patien...
ABSTRACT One of the most important factors playing role in chronic hepatitis B pathogenesis is cytokine release and one of the cytokines with antiinflammatory characteristic is interleukin-10 (IL-10). The aim of the present study was to estimate IL-10 levels and to evaluate the utility of using it as biomarker for monitoring the progression and treatment of chronic hepatitis B infection. Sixty patients with chronic hepatitis B disease confirmed by persistence expression of HBsAg for more tha...
Abstract This cross-sectional study was conducted for six months, from January to June 2013, to estimate the prevalence of internal lesions in slaughtered camels at Tambool slaughterhouse, to isolate and identify the aerobic bacteria colonizing these lesions and to determine the antimicrobial susceptibility profile of these isolates. A total of 280 camels . Samples were taken investigated from carcasses internal lesions at different organs for bacteriological investigation. Internal lesions ...
ABSTRACT Global warming has revitalized interest in the relationship between body size and temperature, proposed by Bergmann’s rule 150 years ago, one of the oldest manifestations of a ‘biogeography of traits’. We review biogeographic evidence, results from clonal cultures and recent micro- and mesocosm experiments with naturally mixed phytoplankton communities regarding the response of phytoplankton body size to temperature, either as a single factor or in combination with other facto...
ABSTRACT The current prevalence of HEY among pregnant women attending antenatal care at major health-care centers in Ekiti State Nigeria was investigated. Ninety (90) serum samples and demographic information were collected from consenting pregnant women aged between 15-45 years and screened for anti-HEY specific lgM antibody using rapid ELISA test kits (CTK Biotech, Inc. USA). Data were analysed using SPSS software version 20.0 and Chi-square test. Three out of ninety (3.3%) serum samples w...
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...
