Scientists from China's Shinkdu University have discovered two new types of deadly bacteria that are resistant to antibiotics in the blood of patients in China.
The Daily Mail newspaper reported yesterday that two patients with an unspecified type of Enterobacteriaceae did not respond to penicillin or cephalosporin from antibiotics in the laboratory.
Intestinal bacteria are present in the gastrointestinal tract and are usually harmless. However, they can cause meningitis if you enter the blood, or pneumonia if you enter the lungs.
Scientists worry about the emergence of new antibiotic-resistant bacteria, which can make life-threatening infections more difficult to cure, while delayed treatment often leads to sepsis.
Dr. Wenging Wu, of China's Center for Infectious Disease Research, led the study, which faces a growing fear of increased antibiotic resistance.
The World Health Organization (WHO) has warned that the world would enter a "post-antibiotic" era if no action is taken.
Enterobacter huaxiensis and Enterobacter chuandaensis were recovered from two patients and received blood samples as part of routine medical care at Western China Hospital.
The genetic badysis of microorganisms revealed that these bacteria were not known before, according to scientists from the Journal of Systematic and Evolutionary Microbiology.
In addition to differences in DNA, the newly discovered strains differed from other intestinal bacteria in their ability to degrade sugars and potbadium salts.
Pneumonia, tuberculosis, gonorrhea and salmonella are part of the growing number of infections that are difficult to treat.
