Respiratory disease

Bacteriology

• Bacterial culture, swine (cults)

• affected areas of lung
• pleural fluid/swab

• Atrophic rhinitis (cults)

• submission of nasal swabs from several pigs is necessary
• consult laboratory for numbers and to obtain swabs (provided for a fee) for testing

Histology

• Immunohistochemistry is available on formalin-fixed tissues for PRRSV, PCV-2, influenza A virus

Formalin fixed:

• sections of SEVERAL pieces of lung from cranial and caudal lobes, including borders of affected and unaffected areas
• trachea, bronchial lymph node

Mycoplasmology

• M. hyopneumoniae PCR and molecular typing (mhpcr) – note: M. hyopneumoniae cannot be cultured

• lung, oral fluids

• Mycoplasma culture (mculf)

• lung

Serology

• PRRSV (prrx3)
• Influenza A virus (H1N1, H3N2) HI (h1n1hi, h3n2hi)
• M. hyopneumoniae (mheiadx)
• Actinobacillus pleuropneumoniae (xappmul) – APP serology is only useful on a herd basis, please phone the laboratory before submitting large numbers of sera
• PRCV (pcve2) – antigenically indistinguishable from TGEV

• serum samples from animals of various age groups
• consult lab for submission details – e.g., the number of samples to be submitted, age of animals to be submitted

Virology

• Influenza A PCR (inflpcr)
• PRRSV PCR (prtqn)
• M. hyopneumoniae PCR (mhpcr)
• PCV-1,2,3 PCR (pcv123)

• lung, tonsil
• nasal swabs in virus transport medium

Comprehensive bovine respiratory disease panel

Includes: (brsppnl)

• bovine viral diarrhea virus
• bovine adenovirus
• bovine coronavirus
• bovine respiratory virus panel PCR (BOHV-1/IBR, BPIV-3, BRSV)
• Mycoplasma bovis PCR
• bacterial culture

• two samples needed per test
• PCR – collect swabs with virus transport medium (VTM) or a swab in 2mL of sterile saline in a red-top tube
• tissue in leakproof container
• may pool up to 5 samples – indicate pooling instructions on submission form
• bacterial culture – swab in bacterial medium or lung tissue, no pooling
• if pooling is requested, individual tests of the panel will be ordered rather than the panel
• AHL splitting charges may apply
