An infectious disease expert says that dangerous bacteria that were normally found in soil and water are on the increase in hospitals worldwide.

Mathew Falagas, who is director of the Alfa Institute of Biomedical Science in Greece, says that Acinetobactor baumannii accounts for almost 30 percent of drug-resistant hospital infections and it is more resistant that MRSA superbug.

Falagas, who is also a professor at Tufts University School of Medicine in Boston, says in a telephone interview, “A baumannii infections are on increase in various hospitals worldwide. As these bugs are resistant to most agents and that’s why these infections are difficult to treat.”

MRSA or methicillin-resistant Staphylococcus Aureus have become a growing problem worldwide, as they cause disfiguring and life-threatening infections which can only be treated with expensive drugs.

According to researchers, Clostridium difficile, a common and sometimes deadly cause of diarrhea, is far more common in U.S hospitals that it was considered. The researchers found that as many as 13 out of every 1000 patients infected by it.

Hospitals, nursing homes and other health care facilities often serve as the nurseries for drug-resistant bugs.

Now antibiotics called polymyxins are being used to fight these bugs. However, these drugs have not been used for the last 20 years, as they have different side effects including kidney problems.
