What is Zoonotic Mycobacteriosis?
Zoonotic mycobacteriosis is an infectious disease caused by Mycobacterium species that can be transmitted from animals to humans. It primarily affects the lungs but can involve other organs, leading to chronic infection.
What Causes Zoonotic Mycobacteriosis?
- Mycobacterium Species – Such as Mycobacterium bovis, which primarily infects cattle but can infect humans.
- Transmission – Through direct contact with infected animals, inhalation of aerosols, or consumption of unpasteurized dairy products.
What Are the Symptoms of Zoonotic Mycobacteriosis?
- Persistent cough
- Weight loss
- Fever and night sweats
- Fatigue
- Enlarged lymph nodes
- In some cases, skin lesions or bone infections
Symptoms may develop slowly over weeks to months.
How is Zoonotic Mycobacteriosis Diagnosed?
- Chest X-rays – To detect lung involvement.
- Microbiological Tests – Sputum culture or tissue biopsy to identify Mycobacterium.
- Tuberculin Skin Test or Interferon-Gamma Release Assays (IGRAs) – To detect immune response to mycobacteria.
- History of Exposure – Contact with infected animals or consumption of unpasteurized milk.
How is Zoonotic Mycobacteriosis Treated?
- Antibiotic Therapy – Long-term treatment with multiple anti-tuberculosis drugs such as isoniazid, rifampicin, and ethambutol.
- Supportive Care – To manage symptoms and complications.
- Monitoring – Regular follow-up to assess treatment response.
Prognosis of Zoonotic Mycobacteriosis
With appropriate treatment, many patients recover, but delayed diagnosis can lead to severe complications.
Can Zoonotic Mycobacteriosis Be Prevented?
- Avoiding Contact with Infected Animals
- Consuming Pasteurized Dairy Products Only
- Using Protective Measures in High-Risk Occupations
- Regular Screening and Control of Animal Infections
