CHP investigates case of NDM-5 Carbapenemase-producing Enterobacteriaceae

     The Public Health Laboratory Services Branch (PHLSB) of the Centre for Health Protection (CHP) of the Department of Health confirmed today (August 14) a case of New Delhi metallo-]-lactamase-5 (NDM-5) Carbapenemase-producing Enterobacteriaceae.

     The patient is a 56-year-old man with underlying illness. He presented with fever and shortness of breath since July 15. He attended the Accident and Emergency Department of Queen Mary Hospital on July 18 and was admitted on the same day. His current condition is stable.

     His rectal swab grew NDM-5 Carbapenemase-producing Enterobacteriaceae upon laboratory testing by the PHLSB. This case has been classified as colonisation.

     Initial enquiries by the CHP revealed that the patient had travelled to Cambodia from July 10 to 13. His home contacts have remained asymptomatic. Investigations by the CHP are proceeding.

     "NDM is an enzyme which can deactivate carbapenems and other beta-lactams such as penicillins. Bacteria harbouring this NDM gene are commonly resistant to multiple antimicrobials, limiting therapeutic options and rendering severe clinical infections difficult to treat. Most bacteria with the NDM enzyme remain susceptible to two types of antibiotics, colistin and tigecycline," a spokesman for the CHP said.

     Infections have varied from being asymptomatic to being potentially life-threatening or fatal. The level of risk depends on which part of the body is affected by the infection and the general health of the patient.

     The spokesman said that proper use of antibiotics and personal hygiene, especially hand hygiene, are important for the prevention of emergence and cross-transmission of NDM strains.
