Munich is facing a measurable uptick in the prevalence of multiresistant organisms, as new data reveals a concerning trend in the city’s healthcare facilities. According to the Munich Health Department (Gesundheitsreferat), there were 406 reported cases of multiresistant pathogens (MRE) in the first half of 2025—an increase of 61 cases compared to the same period in 2024.
This local surge mirrors a broader national crisis in Germany. A study indicated that approximately 9,600 people died in Germany in 2019 due to infections caused by multiresistant germs. In these instances, the lack of effective antibiotic treatment turned manageable infections into fatal ones, highlighting a precarious gap in modern medicine.
The rise of these “superbugs” transforms the very places meant for healing into areas of high risk. For medical professionals on the front lines, the challenge is no longer just treating the primary illness, but defending the patient against the environment itself. As antibiotic efficacy wanes, the focus has shifted toward aggressive prevention and the strict containment of pathogens that have evolved to bypass our strongest drugs.
The Hospital as a Biological Crossroads
Healthcare facilities are uniquely vulnerable to the spread of resistant germs. Patrick Rämer, the 43-year-old head of the Office for Hospital Hygiene and Infection Prevention at München Klinik, describes the hospital as a “hotspot” for multiresistant pathogens. This vulnerability is driven by a combination of patient density and the specific health profiles of those admitted.
The risk is amplified in high-acuity settings such as oncology wards, intensive care units, and dialysis stations, where patients often have compromised immune systems and may require multiple hospitalizations within a single year. The global nature of modern travel means patients arriving from abroad may unknowingly introduce resistant strains into the local ecosystem.
Beyond patient movement, the physical environment poses a constant threat. Pathogens can linger on bed rails, ultrasound machines, CT scanners, and dressing trolleys if sterilization protocols are not meticulously followed. In many cases, the use of multi-bed rooms further accelerates the transmission of germs from one patient to another.
Beyond MRSA: The Emergence of MRGN
While Methicillin-resistant Staphylococcus aureus (MRSA) is the most widely recognized resistant pathogen, clinicians are now more concerned with a different group: multiresistant Gram-negative rods (MRGN). These bacteria are often more difficult to treat because they are naturally more resilient to many common antibiotics.
Within this group, the so-called “4MRGN” bacteria represent a critical threat. These strains are effectively resistant to almost the entire standard arsenal of antibiotics available in a typical hospital. When a patient is infected with a 4MRGN strain, the remaining treatment options are severely limited, often leaving doctors with only a handful of “last-resort” drugs that may carry higher toxicity or lower efficacy.
| Pathogen | Type | Primary Concern | Treatment Status |
|---|---|---|---|
| MRSA | Gram-positive | Widespread colonization | Manageable with specific drugs |
| MRGN / 4MRGN | Gram-negative | High resistance to broad-spectrum drugs | Severely limited options |
| Candida auris | Fungus (Yeast) | High transmissibility; environmental persistence | Limited antifungal options |
The ‘Parking Lot’ Effect and Antibiotic Overuse
The proliferation of these germs is not an accident of nature alone; it is driven by “selection pressure.” The Robert Koch Institute (RKI) warns that when antibiotics are prescribed too frequently or for too long—especially without a confirmed bacterial infection—they clear out the “good” bacteria that normally protect the body.
Patrick Rämer uses a parking lot analogy to explain this biological process. He envisions the human body as a full parking lot, where the spaces are occupied by benign bacteria. When antibiotics are administered unnecessarily, they act as a force that clears the lot, driving the “cars” (bacteria) away.
This creates an opening. When a highly resistant hospital germ arrives, it finds an empty parking lot with plenty of space to settle, multiply, and establish a colony. Had the antibiotics not been used, the resistant germ would have found no room to take hold, effectively blocked by the body’s natural microbial flora.
The Case of Candida auris
The danger is not limited to bacteria. In 2023, a Munich clinic dealt with a “complex outbreak” of Candida auris, a multiresistant yeast fungus first identified in Japan in 2009. The outbreak resulted in seven confirmed infections and 49 colonizations.
Candida auris is particularly troublesome because it is more easily transmitted from person to person than other fungi and is resistant to many common antifungal medications. The outbreak, which ended in 2024, provided critical lessons for Munich’s health authorities, specifically regarding the need for specialized disinfection measures. According to the Health Department, no further infections were reported in 2025.
Strengthening the Frontline of Defense
Because treatment options are shrinking, the primary weapon against MREs is rigorous hygiene. Experts estimate that 30% to 35% of hospital-acquired infections could be prevented through stricter adherence to hygiene protocols.
Munich clinics employ a “basic hygiene concept,” which prioritizes two main pillars: intensive hand hygiene and thorough surface disinfection. Rämer emphasizes that correct hand hygiene is the most critical factor in breaking the chain of transmission. This is paired with the meticulous reprocessing of medical equipment, from ultrasound probes to dressing carts.
To prevent outbreaks, hospitals now implement aggressive screening. Patients admitted from abroad or those suspected of carrying a resistant strain undergo swabs from various body areas. If a test returns positive, the patient is immediately isolated to protect the rest of the ward.

The Munich Health Department continues to monitor the development of multiresistant pathogens with high vigilance. The next phase of oversight will involve ongoing reviews of clinic hygiene measures and the tracking of transmission pathways to prevent further spikes in case numbers.
