What effect did you measure?

What was the difference in effect?

What doses did you apply?

What was the energy of the gamma?

How did you measure the dose?

Habib Saedi

Are u fixed the energy or the time that u applied?

In which medium u carry it?

You indicated

Evaluated the effect of gamma irradiation on the growth and multi drug resistance of bacterial isolates.

Co-60 irradiation of P.aeruginosa

< 1 gray

Reduction in bacterial growth 84%
The percentage of biofilm inhibition increased up to (40%)
Increased the antibiotic sensitivity of P.aeruginosa

10 gray

Reduction in bacterial growth 70%
Biofilm inhibition?
Antibotic sensitivity?

Were these results compared to unirradiated control?

How many times have you observed this effect? What is the average result of several exposures? Were several cultures exposed each time?

Keran O'Brien

They don't.
