WARSAW, Aug. 16 (Xinhua) -- Hundreds of cases of people infected with the so-called "New Delhi" deadly super bacteria, have been reported this year in Poland, local media reported on Thursday.

The deadly bacteria includes an enzyme that makes them resistant to a broad range of antibiotics. The bacteria is therefore particularly dangerous for people with weakened immunity, such as oncological patients or people who had undergone a long antibiotic therapy.

The "New Delhi" bacteria is a common Klebsiella pneumoniae that belongs to the intestinal bacteria, but is resistant to all known antibiotics. It may be responsible for dangerous inflammation of the urinary tract and digestive system or meningitis. The bacteria often dwells in hospitals and might lead to life-threatening sepsis.

According to local media, last year, there were around 2,000 reported cases in the country. Taking into account the cases reported so far, this number is to be exceeded this year.

The first such case of infection in Poland was recorded in 2011, while the bacteria itself was discovered by British scientists only in 2009.

Researchers are worried that the "super bacteria" may transmit resistance to antibiotics to other bacteria, which are now completely susceptible to antibiotics, such as cholera and dysentery, which could have deplorable effects on humanity.
