Hands may be the most important means by which enteric pathogens are transmitted. Skin hygiene particularly of the hands, has been accepted as a primary mechanism to control the spread of infectious agents. Therefore the present study was undertaken to evaluate the number and type of enteric bacterial pathogens associated with hands. A total of 160 hands swab samples of 80 students of KG, PS, SS, UG, and PG were analyzed. Pathogens were isolated from hands includes Escherichia coli (22%), Pseudomonas aeruginosa (12%), Staphylococcus aureus (15%), Proteus mirabilis (11%), Citrobacter freundii (10%), Enterobacter aerogenes (8%), Streptococcus sp. (7%), Klebsiella sp. (6%), Micrococcus sp. (5%) and Salmonella typhi (4%). The prevalence of the bacterial pathogens was high in students of K.G. and primary than those in secondary schools and colleges. The data indicated that the hands of the female were more contaminated than male and the left hand was more contaminated than the right hand. Thus, the potential risk factors for transmission of enteric pathogens through hands should be investigated in order to improve the general health of the students.

Aim: The present study aimed to investigate the impact of the educational intervention for hand hygiene (HH) on knowledge, attitude, and mean colony-forming bacterial counts and type of bacteria on hands of undergraduate dental students. Materials and methods:A total of 86 dental students from different clinical grades were included in the study. They were divided into two groups, group I (55 students) received onetime educational session for HH at the start of the academic year and group II (31 students) received an extra reenforcement session 6 months later. After 2 weeks of reenforcement session, a self-administrated questionnaire was directed to all participants assessing their knowledge and attitude about HH. Fingertip prints of the five fingers of the dominant hand from every participant were pressed onto blood agar plates in triplets at the same clinical session, before and after HH. Bacterial colony-forming units (CFUs) on each plate were recorded and identified microbiologically. Results:The overall scores of knowledge and attitude showed higher levels in group II than in group I with nonsignificant differences between both groups as regards knowledge and significant differences (p < 0.05) as regards attitude. Mean CFUs showed extremely significant differences (p ≤ 0.000) between 2nd and 3rd counts and between 1st and 2nd counts except for students of group I where the difference was only significant (p ≤ 0.05). Normal bacterial flora was identified in 94.9% of the plates (92.2% coagulase-negative Staphylococci and 2.7% Micrococcus). Potentially pathogenic bacteria isolated from the other plates were Klebsiella pneumonia, Pseudomonas spp., and spore-forming aerobic nonhemolytic Bacilli. Clinical significance: Continuous education with frequent training sessions is recommended to reinforce HH compliance and reduce cross-contamination. Impact of Educational Intervention for Hand

“…145 Furthermore, Doring and colleagues showed that Pseudomonas aeruginosa and Burkholderia cepacia were transmissible by handshaking for up to 30 minutes when the organisms were suspended in saline, and up to 180 minutes when they were suspended in sputum. 146 The study by Islam and colleagues with Shigella dysenteriae type 1 showed its capacity to survive on hands for up to 1 hour. 147 HCWs who have hand dermatitis may remain colonized for prolonged time periods.…”
