Isolation And Identification Of Bacteria Of Used Toothbrushes
The Isolation And Identification Of Bacteria Of Used Toothbrushes Project Material
Abstract
Used toothbrushes serve as reservoirs for microorganisms and may play a major role in disease transmission in humans. Forty used toothbrushes obtained from some students of Niger Delta University were analyzed bacteriologically using standard microbiological techniques. The toothbrushes were used twice per day for one month by the students. The result showed that all the toothbrushes were contaminated with bacteria while the unused ones which served as controls were not contaminated. The bacterial isolates from the toothbrushes were Streptococcus mutans, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Enterobacter aurogenes. Staphylococcus aureus was predominantly isolated (30%) from the toothbrushes, followed by Pseudomonas aeruginosa (22%), Staphylococcus epidermidis (18%), Streptococcus mutans (16%), Escherichia coli (8%) and finally Enterobacter aerogenes (6%). Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Streptococcus mutans, Escharichia coli and Enterobacter aerogenes were detected in 60%, 45%, 50%, 25%, 20% and 10% of the samples respectively. In view of the fact that these organisms are pathogenic and could be a potential health hazard, adequate rinsing and air-drying of the toothbrushes before storage will minimize the incidence of these bacteria and the health risk associated with them.
Airms and Objectives
This study evaluated the rate of microbial contamination of used toothbrushes used by students. The objectives of the study is to:
- To identify the microbes regularly associated with used toothbrushes
- To determine the microbial load of used toothbrushes.
- To make a recommendation on remedial measures.
