Often hyperhidrosis, wearing tight shoes. Usually preceded by an insufficiently pre-treated tinea pedis (the usual antimycotics have a "gram-negative gap".

interdigital space between the toes, spreading to the adjacent toe areas and the forefoot

- Broad-spectrum antibiotics. In gram-negative foot infections, the germ Pseudomonas, which is frequently involved, is increasingly resistant to the common preparations Levofloxacin (e.g. Tavanic) 1-2 times/day 500 mg p.o. and Ciprofloxacin (e.g. Ciprobay) 2 times/day 250-500 mg p.o, the following antibiotics are now recommended: Piperacillin (e.g. Piperacillin-ratiopharm) 3-4 times/day 2-4 g i.v.), Ceftazidim (e.g. Fortum) 2-3 times/day 1-2 g i.v.
- Imipenem/cilastatin (e.g. Zienam) 3 times/day 1 g i.v. is reserved for severe infections as a reserve antibiotic.
