An educational intervention for altering water-sanitation behaviours to reduce childhood diarrhoea in urban Bangladesh: formulation, preparation and delivery of educational intervention.

The formulation, preparation and delivery of an educational intervention previously shown to alter hygienic practices and reduce rates of childhood diarrhea in 25 slum communities in Dhaka, Bangladesh is described in detail. Successful aspects of the program included involvement of community members in goal determination, involvement of community members and women as trainers, focusing conflict into positive actions and utilization of informal training techniques. The failures included inadequate transfer of technical aid to communities and insufficient involvement of volunteer-trainers in curriculum development. We suggest possible explanations for these successes and failures and suggest that these hypotheses should, if possible, be subjected to formal evaluation.

Effectiveness of household natural sanitizers in the elimination of Salmonella typhimurium on rocket (Eruca sativa Miller) and spring onion (Allium cepa L.).

Experiments were done with fresh lemon juice, vinegar and their mixture (1:1) to evaluate their efficacy in reducing the numbers of Salmonella typhimurium on fresh salad vegetables. Fresh whole rocket leaves and shredded spring onion samples were inoculated with S. typhimurium suspensions to provide initial populations of approximately 6 and 3 log cfu/g. After inoculation, vegetables were treated with the test solutions for 0, 15, 30 and 60 min, and pathogens were enumerated by using direct plating on Bismuth Sulphite Agar (BSA). Prior to this work, it was shown that BSA was not toxic for acid injured Salmonella cells by statistical analysis applied to enriched and non-enriched samples (P>0.05). Treatment of rocket leaves with fresh lemon juice and vinegar caused a significant reduction ranging between 1.23 and 4.17 log cfu/g and between 1.32 and 3.12 log cfu/g, respectively, while the maximum reduction reached by using lemon juice-vinegar mixture (1:1) for 15 min, which reduced the number of pathogens to an undetectable level. In the spring onion samples, lemon juice, vinegar and their mixture caused 0.87-2.93, 0.66-2.92 and 0.86-3.24 log cfu/g reductions, respectively.

Comparison of floor sanitation methods.

Two methods for cleaning waxed polyvinylchloride and porcelain grès hospital room floors were compared in order to determine their decontamination capacity: dry wiping followed by damp washing, and damp washing followed by dry wiping. Dry wiping followed by damp washing did not produce any significant reduction in the average bacterial load. However, damp washing followed by dry wiping reduced the bacterial load for both types of flooring. The difference was statistically significant.
