Debridement of necrotic tissue was achieved in just 10 days with maggot therapy. 2014;2014:592419. doi:10.1155/2014/592419 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3976885. Maggot debridement therapy is the real-time placement of maggots into a wound by health professionals for the treatment of diabetic ulcers or hard-to-heal wounds infected with antibiotic-resistant bacteria. J Tissue Viability. BMJ 2009; 338 doi: https://doi.org/10.1136/bmj.b773. J. Wayman, V. Nirojogi, A. Walker, A. Sowinski, and M. A. Walker, “The cost effectiveness of larval therapy in venous ulcers,” Journal of Tissue Viability, vol. 5418, pp. 1646–1654, 2010. Larval Therapy for Chronic Cutaneous Ulcers. They will not only inspect the wound you have seen, but look for any other possible sites of infestation as it is possible they are all over the cat's body. 9, article 24, 2010. He started maggot the… She also received vitamin K, pentoxifylline, and 1 dose of zoledronic acid. Each maggot is capable of removing 25 mg of necrotic material from the wound within just 24 hours 18). Microb Infect. Maggot debridement therapy is used to treat and heal certain chronic wounds that have extensive areas of dead tissue. The sterile maggots are then moved from their container to a special piece of nylon netting placed on a nonwoven swab to draw away moisture. 2, pp. 30, no. Cazander and colleagues 88) recently discovered that maggot alimentary secretions and excretions reduced complement activation in healthy and immune-activated (postoperative) human sera by as much as 99.9% by breaking down C3 and C4 proteins. An in-vivo study,” Advances in Skin and Wound Care, vol. J. L. Dimarcq, E. Keppi, B. Dunbar et al., “Insect immunity. 2007;83(980):409–413. It is in this context that debridement, disinfection, or cellular proliferation and migration are so important, for they can push the stagnant wound into the next phase of healing. In this prospective clinical trial, Steenvoorde and colleagues 36) enrolled 64 patients with 69 chronic, necrotic wounds. Maggot therapy is basically a therapeutic wound myiasis, controlled in ways that optimize efficacy and safety. Larvae are covered by minute spines which scrape along the wound base as the maggots crawl ab… 2, pp. K. Y. Mumcuoglu, “Clinical applications for maggots in wound care,” The American Journal of Clinical Dermatology, vol. (adsbygoogle = window.adsbygoogle || []).push({}); (adsbygoogle = window.adsbygoogle || []).push({ The natural habitat of Lucilia sericata larvae is in rotting organic matter such as a corpse or excrement. 85) monitored cyclic AMP (cAMP) in human neutrophils before and after exposure to L. sericata alimentary secretions and excretions and then again in human monocytes 86). More recent studies of larval alimentary secretions and excretions help scientists see just how these proteolytic enzymes fit into the context of debridement and wound healing, for they now know that alimentary secretions and excretions include a wide array of matrix metalloproteinases (MMPs), including at least the trypsin-like and chymotrypsin-like serine proteases, an aspartyl proteinase, and an exopeptidase-like matrix metalloproteinase, active across a wide pH range 24). 208–214, 2002. Antimicrobial killing also occurs outside the maggot’s gut, and the extracorporeal secretion/excretion of antimicrobial compounds may even be responsible for most of the maggot’s antimicrobial activity 41). 6, pp. D. G. Armstrong, P. Salas, B. 9, pp. 2, no. 8, pp. But maggot therapy is one of the few highly effective methods of debridement which can safely and inexpensively be continued throughout the healing process, which may explain why it remains one of the methods of maintenance debridement best associated with faster wound healing. 6, pp. 2, pp. Ophthalmic myiasis – maggot … The use of maggot therapy is on the rise, owing to recognized limitations in our current medical and surgical wound care options. 523–531, 2010. Brown, A. Horobin, D. G. Blount et al., “Blow fly Lucilia sericata nuclease digests DNA associated with wound slough/eschar and with Pseudomonas aeruginosa biofilm,” Medical and Veterinary Entomology, vol. Wounds. 91–94, 2000. D. I. Pritchard, G. Telford, M. Diab, and W. Low, “Expression of a cGMP compatible Lucilia sericata insect serine proteinase debridement enzyme,” Biotechnology Progress, vol. When open wound healing is delayed despite the appropriate antibiotic treatment, especially in tropical or subtropical regions, myiasis should be suspected. Semiquantitative cultures were taken at baseline and before each cycle of maggot debridement therapy. P. Steenvoorde, C. E. Jacobi, and J. Oskam, “Maggot debridement therapy: free-range or contained? Among the early theories about maggot-induced wound healing were that the simple removal of debris and microbial killing 61) or the action of crawling over the clean wound bed 62) might be enough to stimulate wound healing. P. Steenvoorde and G. N. Jukema, “The antimicrobial activity of maggots: in-vivo results,” Journal of Tissue Viability, vol. Larval secretions also contain deoxyribonuclease (DNAse), able to degrade both microbial DNA and also human DNA in necrotic debris 28). 267–271, 1935. For these reasons, maggot debridement was approved by the US Food and Drug Administration in 2004 90). 505–510, 1997. With advanced molecular and biochemical methods now at our disposal, many researchers over the past two decades have focused their attention on isolating antimicrobial proteins and other biochemicals produced by Lucilia sericata 43). 99, no. 1, no. 567–572, 2012. Dumville et al.’s 267-subject randomized controlled trial of maggot therapy for venous stasis wounds 60) did not demonstrate any significant difference between the time-dependent decreasing bacterial burden in maggot-treated patients versus control patients, nor any significant difference in the number of MRSA-colonized wounds that were cleared. The dressing is finally covered with a simple absorbent pad held in place with adhesive tape or a bandage  7). Newspapers have taken slightly different angles on a study into the use of larval therapy for leg ulcers. 667–674, 2013. 3, pp. 10, pp. Apply a dusting of cornstarch to inspect any left maggots in the wound. 3, no. Wollina U, Liebold K, Schmidt WD, Hartmann M, Fassler D. Biosurgery supports granulation and debridement in chronic wounds–clinical data and remittance spectroscopy measurement. The practice is actually approved by the U.S. Food and Drug Administration as a prescription treatment. J. W. Costerton, P. S. Stewart, and E. P. Greenberg, “Bacterial biofilms: a common cause of persistent infections,” Science, vol. Their analysis revealed better outcomes in the free range group compared to the contained maggots group, despite the fact that the free range technique required fewer maggot applications and fewer total number of maggots per treatment. When that infestation is limited to a wound, it is called wound myiasis. 3, no. 54–56, 2009. Experiments performed by Barnes et al 20) have demonstrated that the blowfly Lucilia sericata (Lucilia (Phaenicia) sericata) larvae excretions/secretions are able to inhibit bacteria growth in both stationary and exponential phases. It looks like you have to register (which appears to be free) to access it. 254–257, 2005. Within 2 weeks, maggot-treated wounds were left with only 7% necrotic tissue (0.9 cm²) compared to 39% necrotic tissue (3.1 cm²) in the control group and all maggot-treated wounds were completely debrided within 4 weeks, while most control wounds were still over 33% covered with necrotic tissue.
