Reporting criteria for gram-negative bacteria, Hesse, Germany
| 1. | Every detection of a carbapenemase by molecular methodology 1 |
| 2. | Phenotypic resistance tests (culture + antibiogram) |
| a) Pseudomonas aeruginosa | |
| If resistant to all three of the following antibiotics: | |
| Imipenem, meropenem and ceftazidime | |
| b) Enterobacteriaceae (if not mentioned elsewhere) | |
| If resistant to at least one of the following antibiotics: | |
| Imipenem, meropenem or ertapenem | |
| c) Proteus spp. | |
| Morganella spp. | |
| Providencia spp. | |
| Serratia spp . | |
| In case of resistance to imipenem and resistance to ertapenem or meropenem (an isolated increase of the MIC for imipenem together with normal MICs for meropenem and – if performed – for ertapenem does not require reporting) | |
| d) Acinetobacter baumannii-complex | |
| Enterobacter spp. | |
| Citrobacter spp. | |
| In case of resistance to imipenem or meropenem. (isolated resistance to ertapenem does not require reporting) | |
| Not to be reported are species with intrinsic carbapenem-resistance. These include: | |
| Stenotrophomonas maltophilia | |
| Elizabethkingia meningoseptica | |
| Chryseobacterium indologenes | |
| Burkholderia cepacia | |
1Laboratories are encouraged but not obliged to type carbapenem-resistant bacteria, analyses are offered free of charge by the national reference centre.
