E Coli vs Coryza

[Twinsoffaith]

i bought 2 Roos that were sick and being new I believed they had allergies. Anyway, they infected the flock and my flock started dying. I treated with Tylan. Took a dead bird to my state vet and the prelim report on the lung tissue yello drainage came back E. coli. I'm thinking the Roos were source cause my cages/coop cleaned regularly. The birds getting sick and dying had awful foul smelling drainage, sneezing, lying around. People told me I had coryza. is the E. coli a secondary infection? What do you think happened? The hen I took in for necropsy had already been treated with Tylan off treatment and kept getting sicker after Tylan. Are my birds carriers? Thanks for help

Tylan won't treat E. coli.

The E. coli sure could be secondary to Coryza. If they are pets, you might want to think about treating with enrofloxacin (Baytril).

I agree with you Kathy. The ecoli would be a secondary infection much like if it were MG being a secondary infection with coryza. In addition to Baytril, sulmet or sulfadimethoxine will treat coryza. Baytril is an excellent treatment for ecoli infection. When treating ecoli infections using Baytril, I recommend heavy doses of probiotics also.
All of this said; birds with coryza should be culled. Surviving birds are carriers for life and will infect healthy birds. Ecoli alone can be successfully treated if caught early. A fecal sample sent to a lab will detect severe ecoli infection on a microscopic slide.
