United Kingdom, 44 isolates with NDM-1in Chennai, 26 in Haryana, and 73 in various other sites in Pakistan and India. The authors' analysis of the strains showed that many carried blaNDM-1 on plasmids, which will allow the gene to be readily transferred between different strains of bacteria by horizontal gene transfer. All the isolates were resistant to multiple different classes of antibiotics, including beta-lactam antibiotics, fluoroquinolones, and aminoglycosides, but most were still susceptible to the polymyxin antibiotic colistin. On 21 August 2010, Ontario, Canada, had its first confirmed case of the "superbug" in Brampton. There were other confirmed cases in British Columbia and Alberta. These confirmed NDM-1 infected cases have no relationship with New Delhi, India. The patients or their relatives never travelled to India in the last decade. On 6 September 2010, Japan detected its first ever case of the NDM-1 enzyme. In May 2009, a Japanese man in his 50s who had recently returned from vacation in India was struck with a fever and hospitalized, later making a full recovery. Hospital officials confirmed that tests carried out after the patient's recovery were positive for the NDM-1 enzyme. An environmental point prevalence study conducted between 26 September and 10 October 2010 found bacteria with the NDM-1 gene in drinking water and seepage samples in New Delhi. 50 tap water samples and 171 seepage samples were collected from sites within 12 km of central New Delhi. Of these samples, 20 strains of bacteria were found to contain NDM-1 gene in 51 out of 171 seepage samples and 2 out of 50 tap water samples. On 8 May 2012, the presence of NDM was found in a patient who died at Royal Alexandra Hospital in Edmonton, Alberta. The patient was also found to be carrying an Acinetobacter strain. The patient contracted the bacteria after another patient, who had surgery on the Indian subcontinent, traveled to Canada and was admitted to hospital with an infection. Science Daily reported on the 16 December 2013 that a team of scientists from Rice, Nankai and Tianjin universities found NDM-1 in two wastewater treatment plants in northern China. In fact, the NDM-1 was unable to be removed after several treatments and attempts to disinfect the plants. Disinfection by chlorine, one of the most effective methods currently, also failed to eradicate the beta-lactamase. In June 2014 it was reported that the molecule aspergillomarasmine A from the Aspergillus
