Skin was surgically scrubbed with 2% chlorhexidine gluconate and 70% isopropyl alcohol. Samples were obtained immediately after clipping, after skin was scrubbed, and again 24 hours after clipping. Number of CFUs for both sides of the clipped areas, types of microorganisms, and growth on MacConkey agar were evaluated every 24 hours for 72 hours. Colonies were evaluated for bacterial morphology and Gram stain characteristics. Sites were evaluated 24 hours after clipping for evidence of erythema.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>24 hours after hair was clipped, there was a significantly higher incidence of erythema and higher number of Micrococcaceae bacteria for the side clipped with the No. 40 blade than the side clipped with the No. 10 blade. Number of CFUs did not differ significantly between size of clipper blades.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s005\">\n<jats:title>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Clipping hair with a No. 40 blade resulted in a significant increase in the incidence of erythema and higher number of Micrococcaceae bacteria, compared with results for clipping with a No. 10 blade. These results supported use of a No. 10 clipper blade to prevent erythema and reduce variation in the skin microbiome.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/ajvr.80.9.862","type":"journal-article","created":{"date-parts":[[2019,8,26]],"date-time":"2019-08-26T18:35:17Z","timestamp":1566844517000},"page":"862-867","source":"Crossref","is-referenced-by-count":10,"title":["Evaluation of the number of colony forming units on the skin of dogs after clipping the hair with two sizes of clipper blades"],"prefix":"10.2460","volume":"80","author":[{"given":"Yasmine","family":"Messiaen","sequence":"first","affiliation":[{"name":"1Sierra Veterinary Specialists and Emergency Center, 555 Morrill Ave, Reno, NV 89512."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey D.","family":"MacLellan","sequence":"additional","affiliation":[{"name":"1Sierra Veterinary Specialists and Emergency Center, 555 Morrill Ave, Reno, NV 89512."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Davyd H.","family":"Pelsue","sequence":"additional","affiliation":[{"name":"1Sierra Veterinary Specialists and Emergency Center, 555 Morrill Ave, Reno, NV 89512."},{"name":"1Sierra Veterinary Specialists and Emergency Center, 555 Morrill Ave, Reno, NV 89512."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"Vet Dermatol","doi-asserted-by":"publisher","first-page":"79","DOI":"10.1111\/j.1365-3164.1995.tb00047.x","article-title":"The distribution of bacteria (other than staphylococci and Propionibacterium acnes) on the hair, at the skin surface and within the hair follicles of dogs","volume":"6","author":"Harvey","year":"1995"},{"key":"ref2","series-title":"Front Microbiol","doi-asserted-by":"publisher","first-page":"2145","DOI":"10.3389\/fmicb.2018.02145","article-title":"Bacteria display differential growth and adhesion characteristics on human hair shafts","volume":"9","author":"Kerk","year":"2018"},{"key":"ref3","series-title":"Int J Comptemp Pediatr","doi-asserted-by":"publisher","first-page":"1767","DOI":"10.18203\/2349-3291.ijcp20183367","article-title":"Effect of aqueous chlorhexidine on skin colonization with gram negative bacteria in preterm infants admitted in NICU: a blinded RCT","volume":"5","author":"Balachandran","year":"2018"},{"key":"ref4","series-title":"Staphylococcus epidermis.
