Conservation of hospitals, sinks New studies this week shows that these drains may be a source of horrible and resistant pathogens, even after deep cleaning.
Researchers at the University of the Balearic Islands in Spain are educational leaders. Published Friday in Border in microbiology– They analyze bacteria collected from drainage pipes around a single hospital that has been well maintained and discovered a variety of microbes, weddings, as well as Superbugs that can resist many antibiotics at once. The research shows that the voting of these bacteria in the hospital is more difficult than expected by the researchers.
Antibiotic resistance is one of our urgent health problems in our era. Evaluate These infections kill at least 1.27 million people around the world per year, including 35,000 Americans per year and education has Screened The stubborn bacteria are paired or more than the current annual cancer (about 10 million per year) in the next few decades.
Hospital and other health care facilities are common breeding sites of antibiotics for many reasons. Antibiotic drugs are widely used in these places. Patients are still healthier than usual, causing the infection to be successful and spread like a forest fire between people. With the risks that they know the hospital and their employees regularly, proceed according to the steps to reduce antibiotic resistance, which often includes the deep cleaning of areas where bacteria can live, such as water supply and zinc systems.
Researchers want to test how effective these prevention measures are. They analyze the drainage pipes from the only university hospital on the island of Majorca, which was built in 2001. Accounting with hospital researchers on a regular basis, including sinking and train by BLACH, giving them pressure and chemicals every two weeks. With chlorine once a year
From February 2022 to February 2022. They gather (use cotton) and sample bacteria that are genetic from six five -ward drains: two units from ICU. And microbiology laboratory
Everyone says that they specify 67 bacteria that are different from the drain. While there are differences between the ward, all drains have a variety of bacteria, including the Nower ICU unit that was opened last year. The researchers also separate the species of bacteria related to the hospital infection violently, including Pseudomonas aeruginosa– Klebsiella pneumoniaeand Staphylococcus Oranus– And although it has decreased and flowing in the type of bacteria found in these drains throughout the year. The cleaning process that the hospital uses seems to not affect their overall diversity.
“Here, we show that the hospital is drowning as a host, a bacteria population that has changed over time, despite the flawless cleaning protocols in the hospital, especially when we look.” Senior researchers Margarita Gomila, the professor of the university. BALEARIC ISLANDS Educational Publisher said, “The bacteria we found may be original from many sources from patients, medical personnel and even the environment around the hospital. When established in the drain, the sink, they can spread out, position important risks to patients with immune deficiency above all else.
Researchers found that most of the samples have at least some bacteria that are resistant to many antibiotics, including species of P. Aeruginosa and K. Pneumoniae– In a few bacteria, they also identify the worrisome genes that promote the anti -Carbapenems, which are Nanner's antibiotics, often used as a final choice treatment method for infections that stop responding to other drugs.
Clearly, the researchers did not say that the hospital should stop cleaning the drain. But with the methods that these bacteria are prosperous, even when faced with deep cleaning, it is clear that it must be stopped, or at least slowing the spread of superbugs within these risky environments.
“Cleaning protocols are important and should be used frequently, especially in a separate ward to delay the spread of bacteria that may be dangerous. But in order to reach the lowest point of the problem, it is important to study the source of these bacteria and the transmission route, “said Josélaço.
