Microbiological resistance per bacterium

Micro-organism	Antibiotic	Protocol
Initial resistance
CoNS	Ciprofloxacin	A
Staphylococcus epidermidis	Ciprofloxacin, rifampicin*	A
Enterobacter gergoviae	Amoxicillin/clavulanic acid	A
Stenotrophomonas maltophilia	Ciprofloxacin	A
Staphylococcus epidermidis	Tetracyclin	A
Staphylococcus aureus	Cefazolin**	B
Follow-up resistance
CoNS	Rifampicin	A
Staphylococcus epidermidis	Flucloxacillin, rifampicin*	A
Enterobacter cloacaea	Amoxicillin/clavulanic acid	B
Escherichia coli	Amoxicillin/clavulanic acid	B
Staphylococcus aureus	Clindamycin	B
Staphylococcus aureus	Cefazolin**	B
Escherichia coli	Amoxicillin/clavulanic acid, ciprofloxacin	B

All bacteria cultured which showed resistance for administered antibiotics were included in this table

Antibiotics indicated with an astrisk (* respectively **) were overlapping in resistance patterns in initial and follow-up resistance

^aAlthough most wild-type strains of Enterobacter cloacae are amoxicillin-clavulanic acid resistant, in this case a susceptible strain was cultured before resistance emerged
