At least one Alberta patient is infected with the so-called superbug that has no treatment, a Calgary doctor said Wednesday.

The news comes as alarm over New Delhi metallo-beta-lactamase, or NDM-1 increases, mainly due to concern that the bacteria is resistant to even the most potent drugs.

Dr. Johann Pitout, of Calgary Laboratory Services, said he helped identify the Alberta case whose illness — like most — originated in India.

“I’m aware of one case because they were admitted to a hospital,” said Pitout, who’s also a doctor of pathology and life medicine at the University of Calgary.

“I’m sure there’s more in Canada.”

Researchers say the bacteria is contracted in hospitals in India and Pakistan — often by so-called medical tourists -— and brought back to their home countries.

Some of those procedures involve cosmetic surgery increasingly sought by those looking for cheaper health care.

Many of the cases outside of southwest Asia have been found in the U.K.

It’s still not clear how serious a health impact NDM-1 poses, said Pitout, but the public must remain vigilant.

“We don’t really know if it’ll be a huge issue or not — it’s potentially a big issue,” he said.

“This enzyme causes a resistance to antibiotics and it seems to be very widespread though we don’t know how common it is.”

He said the bacteria usually attacks the lower urinary tract, which isn’t fatal but is known to also target the upper tract, which can be deadly.

Canadian health care-givers and the public need to be aware of the potential danger by sharing information, said Pitout.

“If people do travel to these countries and do go to hospitals and back to Canada to our hospitals, it’s very important for these people to tell about that, so these people can be screened,” said Pitout, who provided a comment on the condition in a report in Wednesday’s Lancet Infectious Diseases journal.

“Probably our biggest worry is the fact you can carry it without knowing you are.”

In a worse-case scenario, an unbridled spread of NDM-1 would have a severe impact on Canada’s already strained health care system, said Pitout.

Scientists say the development and overuse of antibiotics that first appeared in the 1940s have empowered the resistant properties of bacteria like NDM-1.

The Lancet report stated NDM-1 is becoming increasingly common in Pakistan, India and Bangladesh.

Scientists began isolating the bacteria in those countries in 2003, states the Lancet.

The news comes just as the World Health Organization proclaimed the H1N1 pandemic has now passed.
