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 ...
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...
ABSTRACT Fresh healthy carrot promote good health but harbour a wide range of contaminants. To assess the microbial quality of carrots sold in Ibadan, a total of fifteen samples were purchased from five vendors. Samples were analyzed to study the density of microorganisms by standard plate count. ...

ABSTRACT A comparative study was done on the physico-chemical and antioxidant properties of some culinary herbs and local spices. Piper Guiness (Uziza), Xylopia aethopica (Uda), Monodora Myristica (Ehuru) and Trtraleura Tetraopera (Oshsho). The proximate analysis of these spices were done to determine their moisture content, ash content, crude fat crude fibre and protein content. Extraction of the Oleorasin from the spices and soybean oil were done using soxhlet extraction unit with h...
ABSTRACT Thirty ripe mango fruits were pluked under sterile conditions from different geographical locations in Enugu metropolis. The mango fruits were exposed to open environment for 5 – 7 days to allow decay. The decaying mango fruits were washed with sterile water to extract the microorganisms. Using the streak plate method, the microorganisms were inoculated unto a petridish of nutrient agar and incubated for 24 hours at room temperature of 250C. A mixture of bacteria, moulds and ...
ABSTRACT The antibacterial activity of sweet orange(citrus smensin) on staphylococcus aureus and Escherichia coli isolated from would infection was studied. A total number of 100 wound sample were collected form different individual from different age range within 5-8years and examined,. The test organisms S auras and E coli were cultured separately on Nutrient and macconkey agar plate and incubated for 24 hrs at 37)c. the highest isolation of bacterial organisms was obtained in staphylococcu...
ABSTRACT Microbial examination of spoilt Avocado fruits was carried out to obtained the causal organism. A total of 60 avocado from Ogbete Main market and New market Enugu were examined by culturing on nutrient agar and sabourand dextrose agar (SM), for bacteria and fungi causing post – harvest spoilage on the fruits; six bacterial species and six fungal species were isolated. The bacteria include Erwinia SP (66.7%), Streptococcus sp, *25%), E. Coli (18.9%) and staphycoccus sp (33.3...
