BIOCONTROL POTENTIAL OF BACILLUS THURINGIENSIS ISOLATED FROM SOIL SAMPLES AGAINST LARVA OF MOSQUITO

ABSTRACTA major challenge for achieving successful mosquito control is overcoming insecticide resistance. Bacillus thuringiensis which is one of the most effective biolarvacide for control of species of mosquitoes and monitoring of larval susceptibility is essential to avoid resistance development. Mosquito larvacidal activity of Bacillus thuringiensis was assessed by isolating them from ecologically different soil habitats in and around Enugu metropolis. The isolate organisms were confirmed ...

COMPARATIVE ANALYSIS OF PIPEBORNE WATER AND OTHER SOURCES OF WATER WITHIN ENUGU METROPOLIS FOR HUMAN CONSUMPTION.

ABSTRACTComparative examination of three main sources of water supply in Independence layout Enugu was carried out with a view to determine their levels of contamination of bacteria. The sources of water examined are tap water, well water and stream water. The pour plate method was used to examine the water samples. Bacteria isolated from the water samples include coliforms especially Escherichia coli. Stream water and well water were found to contain bacterial isolates unlike the tap water t...

EFFECT OF DIFFERENT CARBON SOURCES ON THE GROWTH OF ANTIMICROBIAL PRODUCING Bacillus Species IN Citrillus vugaris.

ABSTRACTEffect of different carbon sources on the growth of antimicrobial producing Bacillus species in ogiri-egusi sold in Ogbeta, Orie, Artisian, Kenyatta, Enugu State were evaluated using standard microbiological and analytical methods. 12 bacteria were isolated and identified such as Bacillus subtilis,(33.33), Bacillus pumulis (41.66), Bacillus licheniformis (25) were identified based on their colony biochemical characteristics.The isolates of the highest occurrences is bacillus pumilus. ...

HEPATITIS C VIRUS AMONG PREGNANT WOMEN PEOPLE LIVING WITH HIV AIDS ATTENDING CLINIC AT UNTH ITUKUOZALLA

ABSTRACTA total of 50 blood (30 pregnant and 20 HIV) samples were obtained from pregnant women and PLWHA attending clinic at UNTH Ituku-ozalla. Samples were screened for hepatitis c viral infection using the rapid one step hepatitis C virus test strip. Two (6.66%) pregnant women were positive and four (20%) HIV patients were positive for Hepatitis C, giving an overall prevalence rate of (26.7%). The infection was the same in male (3) and in female (3). Those aged 23-34 years recorded a higher...

ISOLATION AND IDENTIFICATION OF BACTERIA FROM FOOD VENDORS AND SOME VEGETABLE AVAILABLE AT OGBETE MARKET ENUGU

ABSTRACTSafety of food is a basic requirement of food quality. A total of 25 street food samples (Jollof rice, egwusi soup, ugu, water leaf and green), were randomly purchased from five different vendors in Ogbete main market Enugu. The samples were transported in ice to the laboratory. The samples were bacteriologically analyzed using pour plate technique and sub-culture. Pour plate techniques was done by carrying out serial dilution of the sample after which the first tube and the last tube...

PARASITOLOGICAL EXAMINATION OF SOME READY TO EAT FRUITS SOLD AT OYE EMENE ENUGU STATE NIGERIA

ABSTRACTSome locally available fruits (garden egg, orange, banana, guava, avocado, pawpaw and pineapple).sold in Oye Emene Enugu, Enugu State was examined for parasitological contamination. A total of 87 samples were examined using sedimentation and concentration methods. 11(12.6%) of the 87 fruits were positive for intestinal parasites microscopically. Among these fruits, guava had the highest number of intestinal parasites which was 6 (35.3% positive and the lowest was banana 2(8%). Parasit...

SUSCEPTIBILITIES OF Salmonella typhi AND OTHER BACTERIAL PATHOGENS TO ANTIBIOTICS AND HOT AQUEOUS EXTRACT OF Hibiscus sabdariffa

ABSTRACTThe susceptibilities of Salmonella typhi and other pathogens to antibiotics and hot aqueous extract of Hibiscus sabdariffa were investigated using agar diffusion and agar well diffusion methods respectively. Salmonella typhi was sensitive to ampicillin, cetriaxone, ciprofloxacin, gentamycin of ofloxacin and perfloxacin. Nitrofurantoin, ampicillin, clarithomycin and augumentin are resistant. Escherichia coli, Klebsiella spp, and Staphylococcus aureus were sensitive to 50%, 70% and 60% ...

Evaluation of Food safety hazards and control in selected fast foods outlets in Ifo Local Government Area, Ogun State

Although the safety of foods served in fast-foods in Nigeria has been an ongoing concern, the unhygienic environments where some fast-foods are located contribute to transmission of foodborne diseases. Health experts in Nigeria have said that the shortage of water may affect the success of any safety campaigns. According to the WHO/UNICEF Joint Monitoring Program (JMP) for water and sanitation (WHO/UNICEF, 2013), only 58 percent of the country’s 160 million people have access to potable wat...

Determining the incidence of Dengue in Ile-Ife

Pyrexia of unknown origin (PUO) is fever that occurs for no apparent reason with failure toestablish diagnosis within one week of investigation. The fever involves temperatures ofgreater than 38.3oC which occurs sporadically for more than three weeks. Fever resolvesusually after about 3 days but can take 2 weeks.Dengue is a tropical mosquito borne-viral disease and is marked by high fever and severe muscle and joint pains. It is caused by any of four antigenically and genetically distinct vir...

ELECTRONIC PAYMENT SECURITY SYSTEM

ABSTRACTElectronic commerce and electronic business are the inevitable mediums of exchange in an increasingly wired world. To better understand the problems and perspectives of electronic payment systems, it is wise to look at not only the current systems in place, but to also examine what the future may hold. This research work describes the characteristics of current systems in place and provides a brief analysis of how each works. Secure electronic payment system is presented in this ...

THE ELECTRONIC PAYMENT SECURITY SYSTEM

ABSTRACTThe financial institutions seek to cut the cost of mediators through direct deal with the consumers and share information with the Internet users as well as encourage customers to pay on-line.

Influence of genetics and environment on grain quality.

AbstractWheat grain quality are strongly influenced by the effects of environment during grain fill. Environmental variables such as temperature, water and fertilizer influence the rate and duration of wheat grain development, protein accumulation and starch deposition in unique ways, and by different mechanisms. The effects of environment are superimposed on the intrinsic temporal patterns of gene expression during grain development. Integration of genomic and proteomic studies with developm...
