I don't believe mine have died without infection.
I'm pretty positive they all had infections.
If it's viral, antibiotics won't touch it.
If it's gram positive, and we're using broad spec gram negative antibiotics such as Ciprofloxacin, then we have another problem.
The biggest question I have is this. Are these bacteria Aerobic, Anaerobic, or Facultative? Maybe Minh can chime in on this one. He and I are both in the medical field, but he knows a lot more than I do.
An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if oxygen is present. An anaerobic organism may be unicellular or multicellular.
There are basically 3 categories of anaerobe:
Obligate aerobes need oxygen because they cannot ferment or respire anaerobically.
Obligate anaerobes are poisoned by oxygen.
Facultative anaerobes can grow with or without oxygen because they can metabolise energy aerobically or anaerobically.
Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However, they are poisoned by high concentrations of oxygen.
Aerotolerant organisms do not require oxygen as they metabolise energy anaerobically. Unlike obligate anaerobes however, they are not poisoned by oxygen.
Obligate anaerobes, which are harmed by the presence of oxygen.
Aerotolerant organisms, which cannot use oxygen for growth, but tolerate its presence.
Facultative anaerobes, which can grow without oxygen but use oxygen if it is present.
