Predominant Bacteria in Domestic Solid Waste Dump in Egbu Owerri North Local Government Area in Imo State, Nigeria

The prevalence of bacteria in solid waste dump from domestic  waste in Owerri was studied. Six (6) samples were collected from Egbu community in Owerri North and examined bacteriologically using Nutrient agar and macconkey agar and were serially diluted, cultured, identified and characterized. Five genera of bacteria were isolated. They are Staphylococcus aurous, Klebsiella sp, Escherichia coli, lactobacillus sp and Corynebacterium sp and from the findings, Klebsiella exhibited the highest (66.6%) number of bacterial activity while Corynebacterium and Iactobacillus exhibited the lowest (16.67%). Futhermore, location D has the highest total hetertropic bacterial count of 5.75x 108 and the least is location E with 6.25x107. T he presence of Escherichia coli, Staphylococcus aureus, Cornebacteria and Klebsiella in the waste dump site is an indication that the contamination is of human and plant orign or their activities. Keywords: Nutrient agar ,macconkey agar, Staphylococcus aurous, Klebsiella sp, Escherichia coli,  Lactobacillus sp and Corynebacterium sp

Comparative Analysis of Petroleum Ether and Aqueous Extracts of Neem Leaf and Neem Stem on Different Stages of Anopheles gambiae

Comparative analysis of petroleum ether and aqueous extracts of neem leaf and neem stem on different stages of Anopheles gambiae was carried out using Soxhlet apparatus. Each plant part extract from both solvents were separately used to test their effects on the developmental stages of Anopheles gambiae. The result showed that the mean mortality of extracts from petroleum ether extraction solvent was higher than that of aqueous extract. It was also observed that mean mortality decreases with increase in developmental stage. Furthermore, extracts from neem leaf was found to be more susceptible than extracts from neem stem using same extraction solvent.
