Molecular characterization of pandemic H1N1 influenza viruses isolated from turkeys and pathogenicity of a human pH1N1 isolate in turkeys.

Suspected human-to-animal transmission of the 2009 pandemic H1N1 (pH1N1) virus has been reported in several animal species, including pigs, dogs, cats, ferrets, and turkeys. In this study we describe the genetic characterization of pH1N1 viruses isolated from breeder turkeys that was associated with a progressive drop in egg production. Sequence analysis of all eight gene segments from three viruses isolated from this outbreak demonstrated homology with other human and swine pH1N1 isolates.

Development and field validation of a Mycoplasma iowae real-time polymerase chain reaction assay.

A Mycoplasma iowae real-time polymerase chain reaction (PCR) assay using primers and probes targeting the 16S rRNA gene was developed and field-validated in this study. The assay specifically identified M. iowae with a detection limit of 80 colony-forming units (cfu) per turkey cloacal swab sample (3.
