#Plasmacluster ions were tested against #tuberculosis (one type of bacteria strain) and found that the ion can kill #Mycobacterium tuberculosis. The #tuberculosis can be spreaded in the air so it is easy for germ contamination. The patients may show the symptom or no show upon the stage. Although there is no show of symptom, they can also be carrier pass through other people. The #Plasmacluster air sterilizer is a choice as the moment and the high concentration of #Plasmacluster ion are more effectiveness in case of #tuberculosis.

Prevention of tuberculosis transmission in patients’s surrounding environment can be achieved by early diagnosis and starting potent short course anti-tuberculosis drugs. And environmental engineering control could be done ventilation, ultraviolet germicidal irradiation and filtered air throught HEPA filter. An Innovation of plasmacluster ion generator has been proved to be effective in killing many viruses, bacteria and moulds in the air but there was no study in Mycobacterium tuberculosis.

Objectives :  To study the efficiency of plasmacluster ion in killing standard strain (H37Rv) and patients’ isolated strains of Mycobacterium tuberculosis in laboratory and time to kill studied strains.

Method :  Standard (H37Rv) and 50 patients’ isolated strains of Mycobacterium tuberculosis were tested in tuberculosis laboratory, department of Pathology. Standard strain was tested for three times. All strains were prepared as suspension of McFarland turbidity scale No.1 and diluted to 1:100 and 1:10,000. The control medium was placed in safety carbinet and not exposed to plasmacluster ions. After exposure, all media were continued incubation and reading of growth of Mycobacterium tuberculosis was done after 3 weeks.

Result :  Standard strains (H37Rv) was not grown after 30 minutes exposure to plasmacluster ions. For patients’ isolated strains, Mycobacterium tuberculosis strains were not grown in 4 (8%) , 4 (8%) , 9 (18%) and 19 (38%) after exposure time of 15, 30, 45 and 60 minutes respectively. 14 strains were still able to grow after expose to 60 minutes but the number of colonies was decreased.

Conclusion :  Plasmacluster ions can kill Mycobacterium tuberculosis on culture media. The ability of plasmacluster ions to kill Mycobacterium tuberculosis in aerosol should be warranted by further study.
