Brucella abortus (B. abortus) Nucleic Acid Test Kit (Lyophilized)

Symptoms

• Reproductive Disorders: In cows, the main symptom is abortion, usually occurring in the second or third trimester of pregnancy. After abortion, there may be retained placenta, endometritis, and vaginal discharge. Infertility is also common, with cows having difficulty conceiving or experiencing repeated early - stage miscarriages. Bulls may develop orchitis and epididymitis, leading to reduced semen quality and fertility.

• Arthritis: Affected cattle may show lameness, joint swelling, pain, and stiffness. The joints most commonly affected are the knee, hock, and wrist joints. Cattle may have difficulty walking, exhibit a stiff gait, and show reluctance to bear weight on the affected limbs.

• General Symptoms: Some infected cattle may have a low - grade fever, loss of appetite, weight loss, and general weakness. There may also be swelling of the lymph nodes, particularly in the submandibular and prescapular regions.

Clinical Applications

• Early Disease Detection: The B. abortus nucleic acid detection reagent allows for the early and accurate detection of the pathogen in cattle. It can identify infected animals before the onset of obvious symptoms, enabling timely isolation and culling to prevent the spread of the disease within the herd.

• Herd Screening and Monitoring: Regular screening of cattle herds using this reagent is an important part of brucellosis control programs. It helps to identify both clinically affected and subclinically infected animals, providing a comprehensive understanding of the disease status in the herd. This is crucial for implementing effective control and eradication measures.

• Differential Diagnosis: Brucellosis can present symptoms similar to other diseases such as leptospirosis and some reproductive - tract infections. The nucleic acid detection reagent helps veterinarians accurately diagnose B. abortus infection, facilitating differential diagnosis and appropriate treatment.

• Import - Export and Quarantine: In the context of cattle trade and movement, the B. abortus nucleic acid detection reagent is widely used for quarantine purposes. It ensures that exported cattle are free from brucellosis, meeting international trade requirements and preventing the introduction of the disease into disease - free areas.

• Vaccine Efficacy Evaluation: After vaccination against B. abortus, the reagent can be used to evaluate the effectiveness of the vaccine. By detecting the presence of the pathogen in vaccinated animals, it is possible to determine if the vaccine is providing sufficient protection and make adjustments to the vaccination strategy if necessary.
