Sheep Pox Virus (SPV) Nucleic Acid Test Kit (Lyophilized)

Symptoms 

• Skin Lesions: The most characteristic symptom is the appearance of papules on the skin. These papules initially present as small, firm bumps that are reddish - purple in color. As the disease progresses, the papules develop into vesicles, which are filled with clear fluid. Subsequently, the vesicles turn into pustules, filled with pus. Eventually, the pustules crust over and form scabs. The skin lesions can be found all over the body, especially on the face, ears, neck, and limbs. In severe cases, the lesions may coalesce, leading to large areas of damaged skin.

• Respiratory Symptoms: Infected sheep may exhibit respiratory problems such as coughing, sneezing, and nasal discharge. The nasal discharge is initially clear but may become thick and purulent as the infection progresses. Difficulty in breathing may also occur, especially in cases where the virus has infected the respiratory tract, causing inflammation and obstruction.

• Systemic Symptoms: Sheep with SPV infection often show systemic symptoms such as fever, loss of appetite, and lethargy. The body temperature can rise significantly, sometimes reaching 40 - 42°C. Due to the loss of appetite, the sheep may experience weight loss and a decline in overall physical condition. In pregnant ewes, SPV infection can lead to abortion, stillbirth, or the birth of weak lambs.

Clinical Applications

• Early - stage Diagnosis: The SPV nucleic acid detection reagent can quickly and accurately detect the presence of the virus in the early stage of infection, even before the appearance of obvious clinical symptoms. This enables timely isolation and treatment of infected sheep, effectively controlling the spread of the virus within the flock. For example, in a large - scale sheep farm, regular nucleic acid detection can identify infected sheep before the disease spreads widely, helping to take prompt preventive measures.

• Epidemic Surveillance: In the event of a suspected SPV outbreak, the detection reagent can be used for large - scale screening of the flock to accurately determine the scope and severity of the epidemic. It helps veterinarians and farmers understand the spread of the virus in the flock, facilitating the formulation of targeted prevention and control strategies. Moreover, for regions with a history of SPV occurrence, regular surveillance using this reagent can help monitor the prevalence of the virus and detect any potential outbreaks at an early stage.

• Differential Diagnosis: Since the symptoms of SPV infection may be similar to those of other skin diseases or viral infections in sheep, such as goatpox or dermatophilosis, the nucleic acid detection reagent is crucial for accurate differential diagnosis. It can specifically identify SPV, allowing veterinarians to distinguish it from other diseases and avoid misdiagnosis and inappropriate treatment.

• Quarantine and Trade Control: In the process of sheep trading and transportation, the SPV nucleic acid detection reagent is an important tool for quarantine. It helps ensure that the traded sheep are free from SPV, preventing the introduction and spread of the virus between different regions. This is of great significance for maintaining the health of sheep flocks in different areas and protecting the sheep breeding industry from the impact of SPV - related economic losses.
