Portable PCR Machine: How Does It Empower Veterinarians to Test Animal Virus?
Release Date 2024-05-13

Veterinarians are constantly vigilant about the threat of animal viruses. The fear is twofold: first, the direct impact on animal health, where viruses can swiftly spread through herds or flocks, causes illness and death. Second, the possibility of these viruses crossing species barriers and infecting humans leads to potential public health crises.

Thus, rapid identification and containment are paramount in preventing widespread outbreaks. One efficient tool for modern veterinarians is portable Polymerase Chain Reaction machines or portable PCR machines. These devices have transformed the landscape of disease detection and control by allowing veterinarians to identify animal viruses rapidly and accurately in the field.

Common Animal Viruses

In recent years, several common animal viruses have spread globally, impacting different species:

Ø Virus in Dogs

There has been a notable outbreak of a canine respiratory disease, which is part of the canine infectious respiratory disease complex (CIRDC). This syndrome can be caused by various bacterial and viral pathogens and is highly contagious. This animal virus has been reported in at least 10 states in the U.S., with cases estimated in the thousands. The clinical signs are often mild but can progress to severe disease and death. This has led to challenges in developing a definitive test and in implementing targeted treatment.

Ø Virus in Swine

Recent global surveillance has highlighted the prevalence of several viruses in the swine population, with significant implications for animal health and potential zoonotic transmission. The African Swine Fever Virus (ASFV) continues to be a major concern, with ongoing research into gene-deleted live-attenuated vaccines showing promise for protecting pigs against this highly lethal disease. Additionally, other viruses such as Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) and Porcine Epidemic Diarrhea Virus (PEDV) are subjects of intensive study due to their economic impact on the swine industry and their potential to cause severe disease in pigs. The genetic diversity and evolution of these animal viruses are critical areas of focus to enhance the understanding and develop effective strategies for disease management and prevention.

Ø Virus in Birds

While the search results do not provide specific recent outbreaks in birds, avian influenza or bird flu, particularly the H5N1 and H7N9 subtypes, has been a recurring concern worldwide. These viruses can not only cause severe disease in birds but also pose a zoonotic risk, infecting humans with serious health implications. Additional viruses of concern in birds include infectious bronchitis virus (IBV) in chickens, which leads to significant economic losses in the poultry business due to reduced egg production and growth inhibition in chickens.

Solutions to Detect Animal Virus

For veterinarians, the choice of diagnostic testing method is critical in managing animal health and disease outbreaks. Here's a closer look at the pros and cons of each method from a veterinary perspective:

1. Viral Culture

It is the traditional method for confirming the presence of a live virus, which is beneficial for animal virus research and vaccine development, including its growth requirements and susceptibility to antiviral drugs.

However, viral culture is a time-consuming process, often taking days to weeks, which can delay diagnosis and treatment. Plus, it requires specialized laboratory facilities and trained personnel. And there is a risk of exposure to the pathogen for laboratory staff, which may not be available in all veterinary clinics.

2. Anti-Body Testing

Antibody tests are valuable for determining past exposure to a virus within a population, offering insights into the immune status and seroepidemiology. These tests are generally less expensive and provide quicker results than other diagnostic methods, making them a cost-effective option for large-scale surveys.

But this solution cannot confirm active infections and may not distinguish between different strains of a virus. Additionally, the presence of antibodies does not always equate to protective immunity, which can complicate the interpretation of results.

3. Antigen Testing

Antigen testing detects the presence of viral proteins, which can indicate an active infection. This method offers a relatively rapid means of diagnosis compared to viral culture and can be adapted for point-of-care testing, which is beneficial for quick decision-making.

However, antigen tests are often less sensitive than nucleic acid tests, leading to a higher risk of false negatives, especially when the viral load is low, as in the early or late stages of infection.

4. Nucleic Acid Testing

Although the cost of nucleic acid testing (NAT) would be higher than other solutions, NAT is highly sensitive and specific, making it the gold standard for detecting viral nucleic acids.

NAT is a type of diagnostic test that detects the genetic material of viruses or other pathogens, such as DNA or RNA. It can identify the animal virus at low levels, even before the onset of clinical symptoms, which is crucial for early detection and intervention. Besides, the NAT allows for the differentiation of virus strains and the monitoring of genetic changes, providing valuable information for tracking outbreaks and understanding transmission dynamics.


Introduction of Portable PCR Machine

The Polymerase Chain Reaction (PCR) machine is a critical tool used to perform NAT. For veterinarians, the PCR machine is one of the effective tools to have PCR testing for dogs, swine, domestic fowl, or other animals. It can effectively detect the animal virus to prevent and control the spread of animal viruses and deliver the clinical solution. Among various kinds of PCR machines, the portable one is suitable for veterinarians to detect animal viruses. Talking specifically, here’s why:

Timely Intervention

Early detection of a viral outbreak is critical in controlling its spread. Portable PCR machines allow for faster identification of pathogens, which can lead to quicker interventions, reducing the impact on animal health and the potential for economic losses.

Sample Integrity Assurance

A portable PCR machine can ensure sample integrity for veterinarians. Samples analyzed immediately after collection are less likely to be compromised by degradation, ensuring that the genetic material remains intact and the results are as accurate as possible. Besides, the elimination of transport delays accelerates the diagnostic process, allowing for faster identification of diseases and immediate implementation of control measures, which is essential in managing outbreaks and preventing further spread.

Accessibility in Remote Locations

Traditional PCR equipment is often large and requires a stable power supply and temperature-controlled environments, which may not be available in remote or rural areas. A portable PCR machine, with its lightweight and compact design, can be easily carried and operated in these challenging environments, empowering veterinarians with diagnostic capabilities where they are needed most.
