Bacteria Load Assessment from Hands of Students in a Tertiary University in South-South Nigeria

Clean hands are the single most important factor in preventing the spread of pathogens and reducing the incidence of infections. The good hand hygiene practices promote health safety and prevent infections. This study was carried out to assess the presence of bacteria from hands of Ambrose Alli University Students. Of all fifty (50) samples analyzed, at least one or two bacteria were isolated. The colony counts of students from each site were properly recorded with the highest found amongst dwellers of male hostels i.e 4.85 x 105cfu/ml, compared to dwellers at female hostels. However, there was considerable increase amongst students at Microbiology laboratory, which may be attributed to lack of good hand hygiene procedures not been adhered to. The considerable increase in the frequency of Escherichia coli and as well as Proteus sp is indicative of poor hygiene practices. The low colony counts recorded amongst students from school gate could be as a result of the student have taken their bath before coming to school. The frequency of occurrence of the isolates includes: Staphylococcus aureus 50 (100%), Escherichia coli 35 (70%), Klebsiella sp 15 (30%), Salmonella sp 21 (42%), Streptococcus sp 10 (20%), Bacillus sp 4 (8%), Pseudomonas sp 2 (4%) and Proteus sp 2 (4%). From the study, it was shown that there was considerable increase in poor hygienic practices amongst students of Ambrose Alli University, Ekpoma Edo State, Nigeria.
