Abstract - Animal health diagnosis
Animal infectious diseases pose a continuing threat to animal health, food safety, national economy, and the environment. Zoonotic infections, also named as zoonoses, involve veterinary pathogens that are sustained in animal populations but can be transmitted to and cause disease in humans. In the event of veterinary outbreaks, it is essential to make rapid and accurate diagnosis to control and prevent the spread of diseases. Here we discuss different diagnostic methods available to identify animal diseases and zoonotic infections. Efficient diagnosis strategies are critical for controlling and eliminating animal diseases and zoonoses, further protecting and improving animal health, quality, and productivity.
Immunohistochemistry (IHC), In situ hybridization (ISH), Virus isolation (VI) - strategies used in diagnosis of animal infectious disease for animal health
2.4 Immunohistochemistry (IHC)
Immunohistochemistry is to detect viral antigen in formalin-fixed paraffin-embedded tissues using virus-specific monoclonal or polyclonal antibodies followed by an enzyme-linked secondary antibody and chemical substrate; IHC can be visualized under alight microscope.
2.5 In situ hybridization (ISH)
In situ hybridization (ISH) is to detect viral nucleic acid present in fixed tissues using a labeled complementary DNA, RNA or modified nucleic acid strand. Different with PCR approach where viral nucleic acid in a sample is amplified before detection, ISH detects viral nucleic acid that is not going through an amplification process.
2.6 Virus isolation (VI)
Obtaining the virus isolate that can efficiently grow in cell culture is critical for pathogenesis study, development of diagnostic assays, and vaccine development. However, viral culture results do not yield timely results to inform clinical management. Shell-vial tissue culture results may take 1-3 days, while traditional tissue-cell viral culture results may take 3-10 days. Due to the long incubation time, high technical requirements, and must be carried out in a level III safe biological laboratory, it is not suitable for rapid virus diagnosis during the epidemic period [17].
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.
