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% ...

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...

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...

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...

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. ...

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.

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...

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 ...

ANTIBACTERIAL ACTIVITY OF HONEY ON Staphylococcus aureus Escherichia coli and Streptococcus pyogen ISOLATED FROM WOUND

ABSTRACTAntibacterial activity of honey obtained from two different locations in Enugu State (Nsukka & Ugwuaji) Nigeria on Staphylococcus aureus, Escherichia coli and Streptococcus pyogens isolated from wound was studied. Agar well diffusion method was used to determine the antibacterial activity of the honey on the test microorganisms. The result revealed that the two honey samples have heavy antibacterial activities against the test organisms and zones of inhibition were obtained showing hi...
