Video: #44 -More than meets the eye: respiratory diseases in swine - Drs. Michael Rahe and Rachel DerscheidYou know what they say: not everything is as it seems... That's especially true for diagnosing respiratory diseases in swine: interpretation can be quite a challenge. That is because a respiratory infection may look like a specific disease, but this does not mean we are going to get that diagnosis once we do a PCR. For example, producers and veterinarians are used to seeing post-weaning respiratory diseases with influenza clinical signs; still, we may not get PCR-positive results for influenza in those situations. With that in mind, I talk with Drs. Michael Rahe and Rachel Derscheid about such respiratory issues, especially related to Porcine Astroviruses.
