your right mate! I've used Nyfuramycin in the past if my young birds look a bit off colour, but these days i use Adenosan and am pleased with the results.
Nifuramycin is used to treat the following infections. • Bacterial infections • Coli infections • Salmonellosis (Paratyphus) • Bacterial infections of the respiratory organs • General stress situations
In the past when I have treated for Paratyphoid I used Parastop from Pantex. It's dosage was 1ml per litre of water for 10 days the active ingredient was Norfloxacin.
