’Tis the Season for Swine Respiratory Diseases: Tips for Diagnosis

Extreme climate changes can frequently trigger malady flare-ups in swine. To help in deciding a conclusion, Dale Miskimins, DVM, a pathologist in the South Dakota State University Veterinary and Biomedical Sciences Department, offers a couple of tips to enable makers to get to the foundation of the issue.

When it comes time to send in analytic examples, pick creatures, both live and dead intensely influenced pigs, that are untreated at whatever point conceivable. On the off chance that creatures can’t be submitted, he proposes picking these tissue tests: tonsil, trachea-affected lung and mediastinal lymph nodes. In the event that lung sores differ, incorporate a few bits of lung. Put copy pieces in 10% formalin.

Filling out the correct diagnostic laboratory forms will help lab diagnosticians and speed up the process. Always identify tissue containers, especially if they are from different ages, pens or barns, he advises.

“Respiratory disease is often a combination of viral and bacterial agents,” Miskimins says. “The laboratory will do appropriate testing to sort out problems. The workup will most likely include necropsy by a veterinary pathologist, histopathology, bacteriology, virology and molecular diagnostics (PCR testing).”

Common Viral Agents
The most common viral agents include:
•    Porcine reproductive and respiratory syndrome virus (PRRSV)
•    Swine influenza virus (SIV)
•    Type 2 circovirus (PCV 2)

Common Bacterial Agents
The most common bacterial agents include:
•    Pasteurella multocida
•    Streptococcus suis
•    Haemophilus parasuis
•    Mycoplasma hyopneumoniae
•    Mycoplasma hyorhinis

“A complete investigation will help both you and your veterinarian identify causes of respiratory disease, limit losses and return your operation to better health,” Miskimins says.

If you have questions on sampling, contact your local diagnostic laboratory.
