To ascertain the effect of larval therapy against bacteria associated with infected chronic wounds, and determine if larvae therapy actively reduces the bacterial load in chronic wounds.
An extended literature review was undertaken using online databases: Athens, Medline, EMBASE, British Nursing Index and Allied and Complementary Medicine via OV ID and Cumulative Index to Nursing and Allied Health. Key terms were searched worldwide from 1950 to 2011.
Four themes emerged: Gram-positive and Gram-negative bacteria, MRSA, quorum sensing: biofilm consideration and bacterial burden. This suggests larvae debridement therapy is differentially effective against both Gram-positive and Gram-negative bacterial strains, namely Staphylococcus aureus, Pseudomonas aeruginosa and meticillin-resistant Staphylococcus aureus.
The evidence supports the use of antimicrobial properties of larvae therapy against the bacteria of infected chronic wounds.
