Infection of toe webs by gram-negative bacteria

Toe web malodorous maceration with well‐demarcated punch‐out edge

“…Foot intertrigo is a spectrum of relatively common and troubling disorders in humid weather or occluded conditions (1). It can be induced by Candida albicans, gram-positive bacteria and gram-negative bacteria as well, the latter of which was defined as a distinct disorder of GNTWI by Amonette and Rosenburg in 1973 (2). GNTWI usually begins with erythema, vesiculopustules, erosion, maceration and malodorous exudate that mainly affect the interdigital area of the feet.…”

Green Foot

“…In spite of the presence of moisture and occlusion, our patient only colonized his shoe and not the skin. Immersion foot and toe web infections occur with humidity and heat (3,10,11). In these infections, Pseudomonas is frequently the pathogen and may be associated with a green discoloration {3, 10,11).…”

“…Immersion foot and toe web infections occur with humidity and heat (3,10,11). In these infections, Pseudomonas is frequently the pathogen and may be associated with a green discoloration {3, 10,11). Proteus mirabilis may also be the primary pathogen in toe web infections (11) or paronychia (2).…”

“…In these infections, Pseudomonas is frequently the pathogen and may be associated with a green discoloration {3, 10,11). Proteus mirabilis may also be the primary pathogen in toe web infections (11) or paronychia (2). Although Proteus paronychia can cause a green nail (2), we did not isolate that organism from our patient.…”

The Environment and the Microbial Ecology of Human Skin

“…The increased use of antibacterial soaps and cosmetics has caused concern that these compounds may upset the balance between gram-negative and gram-positive populations. Abnormal usage of antibacterials on skin has shown to result in a decline in the gram-positive population and an increase of colonization by gram-negatives (1,19), The medi-cal center group, however, was not found to have a higher frequency of isolation of gramnegatives than laborers, although in axillae the relative proportion of gram-negative to grampositive populations was higher. The Coast Guard personnel, however, had a higher frequency of isolation of gram-negative bacteria from the back, feet, and axillae, and relative roles of antibacterials versus humidity can be debated.…”
