Antibiotic sensitvity and plasmid profiles of bacteria isolated from water sources in Oproama community in the Niger Delta

The antibiotic sensitivity pattern and plasmid profile of Escherichia coli, Vibrio and Salmonella species isolated from well and river water sources in Oproama Community were investigated. Antibiotic sensitivity profiles of the bacteria (Escherichia coli, Vibrio sp. and Salmonella sp.) isolated from the water showed high sensitivity to oflaxicin, nalidixic acid and nitrofurantoin and high resistance to amoxicillin, augumentin, cotrimazole and tetracycline. Multi antibiotic resistant index (MARI) as high as 0.375 (Escherichia coli: E9; Vibrio spp.: V3, V4, V10; Salmonella spp.: S1, S9), 0.5 (Vibrio spp.: V2; Salmonella spp.: S2, S4) and 0.75 (Salmonella spp.: S7) were recorded after curing the plasmids with sodium deodecyl sulphate (SDS). The plasmid profiles revealed that 60% of the isolates harboured detectable plasmids with sizes up to 23.130 kb.Keywords: Antibiotics, Escherichia coli, Plasmid, Salmonella, Vibri

Enterotoxicigenicity profile of Escherichia coli , Vibrio , and Salmonella species isolated from well and river water sources in Oproama town in the Niger Delta, Nigeria

Well water is the only source of drinking water in Oproama Town in Rivers state, Nigeria. Water from these sources is consumed without treatment, and potentially poses a health risk to the local population. The Enterotoxigenicity profile of Escherichia coli , Vibrio and Salmonella species isolated from well and river water sources in Oproama were investigated using fluid accumulation (FA) ratio. The study revealed that Salmonella isolate (S9) from the river showed doubtful toxicity out of the ten Escherichia coli, ten Vibrio and ten Salmonella isolates. This study revealed a near-absence of enterotoxigenic Escherichia coli, Vibrio and Salmonella organisms from the waters in Oproama. More studies are required to further test the overall safety of these water sources due to the potential risk of consuming untreated water

HIV/AIDS Awareness Level of First Students of a Tertiary Institution in Rivers State, Nigeria

This study examined the knowledge, attitude and preventive practices (KAP) of 250 first year Nigeria students regarding HIV/AIDS, in July 2002. Data was collected by both quantitative method using structured questionnaires and by qualitative method through focus group discussion (FGD). Respondents had a mean age of 22.2 years, were mainly Christians (98.4%), single (97.2%), and lived off-campus (80.8%). Information from the FGD was quite comparable to what was obtained through questionnaires. Only 4.4% could define HIV correctly while 33.6% defined AIDS correctly. Majority (84.4%), knew that HIV causes AIDS, 73.6% knew that youths were the age group most at risk, 37.2% thought there was a cure while 39% knew there was no effective vaccine for AIDS. More than half (57.2%) , were concerned about contracting HIV with 67.2% believing HIV/AIDS was in their school, however 80.6% had never been tested for HIV. The FGD exposed the misconceptions and chauvinism of some male participants on HIV/AIDS issues and the inadequacy of knowledge of participants. Although some knew important routes of transmission and ways of prevention, they need more education on HIV/AIDS issues.
