Australian scientists say a commercially available compound made of proteins produced by Staph bacteria has been used to successfully fight mesothelioma in lab mice.

Researchers at the University of Western Australia treated mesothelioma cells with the S. aureus mixture and found that it killed the cancer cells while simultaneously stimulating a stronger anti-tumor response in healthy cells.

“Tumour growth was significantly inhibited in the treatment group during and after the treatment period,” writes lead study author Dr. Sally M. Lansley with the University’s Centre for Asthma, Allergy and Respiratory Research.

The study in Respirology, found that, when the compound was injected into the tumors of mice with pleural mesothelioma, mesothelioma cells died. When the treatment was discontinued, mesothelioma tumors began to grow again.

“The fact that this Staph aureus compound is commercially available puts it a step ahead of many experimental mesothelioma treatments,” says Alex Strauss, Managing Editor of Surviving Mesothelioma. “The lack of side effects is another encouraging aspect of this study.”
