Case Report

Severe Wound Infection with Photobacterium damselae ssp. damselae and Vibrio harveyi, following a Laceration Injury in Marine Environment: A Case Report and Review of the Literature

Table 2

Result of disc diffusion test (except amikacin, which was tested with -Test) with P. damselae on MUELLER-HINTON agar after 24 hrs of incubation at °C. The antimicrobials tested are those routinely used for Gram-negative isolates in the laboratory of one of us. The categorical interpretations (S: susceptible; R: resistant) are based on the CLSI recommendation for Vibrio ssp. (excluding Vibrio cholerae) as implemented in the Sirweb software (i2a, Pérols Cedex, France). Antimicrobials capitalized with “*” are those recommended for first-line testing, those in CAPITALS indicate antimicrobials recommended for testing, and those in italics are antibiotics tested routinely in our lab with Gram-negatives on MUELLER HINTON agar, but are not recommended by Clinical and Laboratory Standard Institute (CLSI) when testing Vibrio species.
