Immunofluorescence staining (IF) - strategies used in diagnosis of animal infectious disease for animal health

The immunofluorescence staining is to detect viral antigen using virus-specific monoclonal or polyclonal antibodies fluorescent staining of viral antigens is visualized under a fluorescent microscope. Picture loading failed.
Figure 3. Immunofluorescence staining of vaccinia virus infected cell [16]. Areas of virus assembly within the cell are pink. Host and viral DNA (deoxyribonucleic acid) is blue. The host cell's DNA is contained within its nucleus (large oval). Actin protein filaments, which make up part of the cytoskeleton, are green.

Summary

In the recent years, importance of animal disease and their public health effects have been well recognized worldwide. Animal disease, more significantly, zoonotic disease cause human mortality and morbidity, and also affect livestock’s production, decrease availability of food and create barriers for international trade. Rapid diagnosis is critical for the implementation of efficient control strategies against animal disease and zoonotic disease. Understanding animal disease infection dynamics and collecting appropriate specimens at the appropriate time window are also important to obtain reliable diagnostic results. A number of virological and serological methods have been developed and used for animal disease diagnostic testing. RT-PCR is the method of common choice for the detection of animal disease; IHC combined with hematoxylin and eosin staining has also been commonly used to examine histopathological lesions caused by animal disease. Success rate of virus isolation in cell cultures has been low. Serological assays can provide information about previous exposure to animal disease and also determine antibody responses to infection or vaccination when vaccines are available. Rolling out serological test would be an effective strategy to determine the percentage of the population that is immune and have shown no symptoms for the animal disease. Thereby, determining the exact magnitude of the outbreak and enabling governments to assess containment strategies to slow down the spread. The major drawbacks with these immunoassays are their accuracy and sensitivity of the test results. Therefore, there needs to be extensive research and testing done to develop new cost-effective methods to quickly and easily determine animal disease infection. Whereas, any such emerging approach must be carefully evaluated for its efficiency, accuracy, and linear range. The FDA approval and evaluation of each diagnostic technique is necessary before it can be used in practice.
