Respiratory Infection

[BoiseBallz]

This is precisely why you culture immediately, and start with a broad spectrum antibiotic such as Baytril or Ceftazadime. There's no reason to throw antibiotics at something without knowing what it is.

This is an oxymoron. Starting broad-spectrum antibiotics before getting culture and sensitivity results is the very definition of throwing antibiotics at something without knowing what it is.

As already stated, by the time you get culture and sensitivity results, you will have already successfully treated the vast majority of cases. So, in the vast majority of cases, culture and sensitivity wouldn't change therapy, and would be a waste of time and money. You are certainly entitled to your opinion. I am just explaining the reasoning behind what is considered the standard of care. It's the same reasoning behind why humans aren't getting cultured for respiratory infections left and right. I have had many respiratory infections in my lifetime, and I suspect you have as well. I have never been cultured, and I suspect that you haven't either. You don't have to agree with the reasoning, but the reasoning is sound and is based on statistical likelihoods over large populations.
