“…IgM and IgA occur in saliva at lower concentrations. 28 Antiviral antibodies as well as elements of viruses can also be detected in saliva and can be used to detect viral infections. 39 In the 1970s and 1980s, local antibody production by serum-derived plasma cells in salivary glands and DALT (duct-associated lymphoid tissue) was reported.…”

“…46 Several studies confirmed the usefulness of OF in the detection of PCV-2 infections and for testing the prevalence of PCV-2 in pens. 28,56,58 Research has also shown that the amount of PCV-2 in saliva is higher, which means that detection of the virus is possible earlier and longer in OF than in serum. 19 Interpretation of rtPCR reaction results and detected amounts of PCV-2 must be carried out carefully, considering the uncertain number of animals in contact with the OF collection rope and the fact that individual animal shedding levels may vary.…”

Noninvasive strategies for surveillance of swine viral diseases: a review

In view of the intensive development of the swine industry, monitoring and surveillance of infectious diseases require low-cost, effective, and representative population sampling methods. We present herein the state of knowledge, to date, in the use of alternative strategies in the monitoring of swine health. Blood sampling, the most commonly used method in veterinary medicine to obtain samples for monitoring swine health, is labor-intensive and expensive, which has resulted in a search for alternative sampling strategies. Oral fluid (OF) is a good alternative to serum for pooled sample analysis, especially for low-prevalence pathogens. Detection of viral nucleic acids or antiviral antibodies in OF is used to detect numerous viruses in the swine population. Meat juice is used as an alternative to serum in serologic testing. Processing fluid obtained during processing of piglets (castration and tail-docking) may also be used to detect viruses. These matrices are simple, safe, cost-effective, and allow testing of many individuals at the same time. The latest methods, such as snout swabs and udder skin wipes, are also promising. These alternative samples are easy to acquire, and do not affect animal welfare negatively.
