The study reminded health agencies to strengthen surveillance and assess the impact of this superbug.
Staphylococcus epidermidis is a bacterium that breeds on the epidermis of living organisms and is parasitic on human skin and other parts, which is the main cause of iatrogenic infection. In recent years, the resistance of this bacterium has received increasing attention.
Researchers at the Peter Doherty Infection and Immunology Institute in Australia analyzed hundreds of strains of S. epidermidis in 78 medical institutions around the world and found that three subtype strains are resistant to almost all antibiotics.
The researchers said that the current treatment of Staphylococcus epidermidis is a combination of two commonly used antibiotics to prevent bacteria from developing resistance to one of them. However, Staphylococcus epidermidis, which has been genetically altered, is resistant to both antibiotics.
Researchers believe that there are two main reasons for the spread of drug-resistant Staphylococcus epidermidis. First, implants such as catheters are often used for anti-infection and antibiotics, which may promote bacterial resistance. Second, patients in intensive care units usually use strong antibiotics in large quantities, which makes the bacteria here more resistant. Medicinal.
Ben Howden, director of the Department of Microbial Diagnostics at the Institute's Public Health Laboratory, said the study showed an urgent need to establish an international surveillance system to understand the prevalence and impact of Staphylococcus epidermidis, while systematically assessing the pathogen-caused Antibiotic resistance and infection problems.
