    I was wondering if I could get some advice.

    As a bit of history - I bought four new hens about a month ago. They went through quarantine fine so I integrated them with the flock. Almost immediately, one started sniffling. In my naivety I didn't check it right away and let her run with the others for a couple of days before I thought 'I must look that up online'. Then, to my horror, mycoplasma reared its head and though I isolated her, many others have also become snuffly. All are still eating and drinking, and to look briefly at the flock, you wouldn't know anything's wrong. But, eggs have decreased, I can notice some lethargy and both my roosters have had bubbles in their eyes - no hens have. Some of my hens sneeze, have some snot or have rattling breath. All myco symptoms, right?!

    So, I had the first hen test at the vets - both the fecal and throat swab came back negative for myco but positive for e. coli, staph and acinetobacter. I've got them on Tylan which will kill off the first two apparently, but they may need something stronger for the acineto.

    Anyway....have I got myco and the test missed it? Or can these other infections show themselves with similar symptoms? I was SO relieved when it came back myco negative but I'm not 100% trusting having read up on it and seen my hens.

    I know this is an old post but i have a culture of e coli and
    Acinetobacter. Didnt do the myco test. Specialist at the lab said it doesnt matter that much but im still thinking of doing it. Im going to switch them to Clavamox per vet recommendations.

    I am no expert on mycoplasma, but a close friend who is head of microbiology at out local hospital has told me a few times that mycoplasma is very difficult to test for. So, he says that many tests will come back negative, but may acrually be positive due to the organism being difficult to culture. Oddly enough, he has had mycoplasma himself. In chickens the Elisa test was fairly routine, but he says that is now outdated. They do DNA testing for it now. I would contact your state poultry vet and discuss your problem. An antibiotic would need to be affective for both gram negative and gram positive bacteria to treat mycoplasma and E.coli.
