Methods of treating or preventing biofilm associated infections with free available chlorine free available chlorine water
The invention provides methods of treating or reducing the incidence of an infection in a mammal due to a biofilm associated infectious microorganism comprising administering a therapeutically effective amount of free available chlorine (FAC) water to a site populated with biofilm associated infectious microorganism.
1. A method of treating or reducing the incidence of inflammation associated with a biofilm containing an infectious microorganism on an oral mucosal tissue in the oral cavity of a mammal, the method comprising disaggregating the biofilm by contacting the biofilm on the oral mucosal tissue with a therapeutically effective amount of free available chlorine (FAC) water for at least about 30 minutes, wherein:
(a) the pH of the FAC water is from about 7.3 to about 7.5,
(b) the concentration of oxychlorine species in the FAC water is 150 mg/L to 200 mg/L, and
(c) the infectious microorganism is selected from Pseudomonas sp., Haemophilus sp., Pneumococcus sp., Mycobacterium sp., Stenotrophomonas sp., Streptococcus sp., Escherichia sp., Mycoplasma sp., and combinations thereof,
to treat or reduce the incidence of the inflammation associated with the biofilm.
2. The method of claim 1 , wherein the infectious microorganism is in a preinfectious commensal state.
3. The method of claim 1 , wherein the mammal is a human patient.
4. The method of claim 3 , wherein the mammal has an immunodeficiency.
5. The method of claim 3 , wherein the FAC water is administered as a lavage, drop, rinse, spray, mist, aerosol, steam or combination thereof.
6. The method of claim 3 , wherein the FAC water is administered in the form of droplets having a diameter in the range of from about 0.1 micron to about 100 microns.
7. The method of claim 3 , further comprising administering at least one antibiotic agent.
8. The method of claim 1 , wherein the FAC water is stable for at least about two months.
9. The method of claim 1 , wherein the FAC water comprises a mixture of cathode water and anode water.
10. The method of claim 1 , wherein the oxychlorine species is selected from the group consisting of hypochlorous acid, hypochlorite ions, sodium hypochlorite, and mixtures thereof.
11. The method of claim 1 , wherein the FAC water reduces the concentration of viable bacteria in the biofilm by at least about 2 logs within 60 minutes.
12. A method of treating or reducing the incidence of inflammation associated with a biofilm containing an infectious microorganism on an oral mucosal tissue in the oral cavity of a mammal, the method comprising disaggregating the biofilm by contacting the biofilm with a therapeutically effective amount of free available chlorine (FAC) water for at least about 30 minutes, wherein:
(a) the pH of the FAC water is from about 7.3 to about 7.5,
(b) the concentration of oxychlorine species in the FAC water is 150 mg/L to 200 mg/L, and
(c) the infectious microorganism is selected from Pseudomonas sp., Haemophilus sp., Pneumococcus sp., Mycobacterium sp., Stenotrophomonas sp., Streptococcus sp., Escherichia sp., Mycoplasma sp., and combinations thereof,
to treat or reduce the incidence of the inflammation associated with the biofilm, and
wherein the method further comprises administering to the mammal at least one antibiotic agent.
13. The method of claim 12 , wherein the infectious microorganism is in a preinfectious commensal state.
14. The method of claim 12 , wherein the mammal is a human patient.
15. The method of claim 12 , wherein the FAC water is stable for at least about two months.
16. The method of claim 12 , wherein the FAC water comprises a mixture of cathode water and anode water.
17. The method of claim 12 , wherein the oxychlorine species is selected from the group consisting of hypochlorous acid, hypochlorite ions, sodium hypochlorite, and mixtures thereof.
18. The method of claim 1 , comprising contacting the biofilm with the FAC water for at least about 60 minutes.
