Briefly, Bello and Peteroy-Kelly (2007) conducted a RCT
looking at the relationship of triclosan antimicrobial
products for home use. Findings included:   1)a
relationship exists between antibacterial soaps and
pathogen resistance. Specifically,they found there was
an association between the use of products with
Triclosan and an increased resistance of bacteria to
ciprofloxacin.   2) concern over the increased use of
antimicrobial agents for home has contributed to the
multi-resistant pathogens that have been treated in the
past such as staph aureus, escherichia coli, and
psuedomonas aeruginosa.  They conclude by suggestion
that everyday use of antimicrobial soaps do not
demonstrate any added benefits to hand hygiene in
comparison to plain soap and the dangers of using
antimicrobial soap may include drug resistance to the
various pathogens mentioned above.

Aiello, Larson, and Levy (2007)conducted a literature
review examing the benefits of handwashing with
antimicrobial incomparison to plain soap. They found
that essentially there was no difference in the efficacy
of using antimicrobial soap in reducing bacteria levels
on hands. Although most studies were small evidence
suggested that "triclosan-adapted cross-resistance with
antibiotics among multiple species of bacteria"
(p.146)is a concern and should be addressed by the FDA.
