Insights
Mycobacterium fortuitum caused severe pneumonia in a young Corgi. Prompt antibiotic treatment led to a favorable outcome, highlighting the need to consider mycobacterial infections in canine respiratory disease.
Area of Science:
- Veterinary Medicine
- Microbiology
- Canine Pathology
Background:
- Bacterial pneumonia is a common respiratory ailment in dogs.
- Mycobacterium species, particularly non-tuberculous mycobacteria, can cause opportunistic infections.
Observation:
- A 1-year-old Corgi presented with a 10-day history of productive cough.
- Radiographic and cytologic findings indicated acute suppurative bronchopneumonia.
Findings:
- Mycobacterium fortuitum was identified in bronchial fluid samples.
- The dog showed a positive response to a combination of gentamicin, cephalexin, and ciprofloxacin therapies.
- Treatment involved initial intravenous antibiotics followed by a six-week oral course.
Implications:
- Mycobacterial pneumonia should be considered in young dogs with severe pulmonary consolidation.
- Early diagnosis and appropriate antimicrobial therapy are crucial for successful treatment outcomes.
- This case underscores the importance of identifying specific pathogens for targeted veterinary care.
Abstract:
Mycobacterium fortuitum was isolated in a sample of bronchial fluid collected by transtracheal aspiration from a 1-year-old Corgi dog with a productive cough of 10 days' duration and with radiographic and cytological features of acute suppurative bronchopneumonia. The dog responded favourably to intravenous gentamicin and cephalexin for three days and a six week course of oral ciprofloxacin. Saprophytic mycobacterial pneumonia should be considered in cases of severe pulmonary consolidation in young dogs.

Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
