Hello.
Need your help.
I'm doing an investigation work in Angola, in a remote place. I came across this new bottled water company. They have a nice lab but lacks some material.
I was asked to help them.
The water pH is around 4,76 to 5,20...low EC (4 - 5 microS); no fecal coliforms; E.fecalis; but positive for P.aeruginosa.
Detection of P.aeruginosa was carried out using membrane filtration method and incubated in centrimide agar.
Then i realise that the CN culture media did not have or was not added the nalidixic acid.
.
The colonies that grow are small, not caracteristic of P.aeruginosa.
I do not have any confirmation test (oxidase test), only fluorescente lamps.
My question is what can i do? what other bacteria can grow in centrimide agar without nalidixic acid?
I attached pictures.
Thank you in advance.
