Hi Team :)
It seems like the main villain in terms of nosocomial infections in Ocotal are Enterobacteria. I did some research and these bacteria are catalase positive and nitrite positive. This is test the other team used two years ago to detect nitrite.
It turns out that Enterobacteria are capable of reducing nitrates to nitrites (which can then be detected by the colorimetric test using the Griess reagent). All the chemicals are fairly non-toxic, so it could be yet another test we could use.
Finally, if catheter acquired UTIs are not a particularly big problem in NicaraguaI think we could target NICU instead. Noel said it was a big problem since these babies don't have a developed immunological system. The form factor is this case would be more straightforward. The "tag" or "sticker" would be visible to the hospital staff but also to the parents, who would make sure something is done is case there is a color change.
Any thoughts?
