Study Notes
Avian & Reptile Respiratory Diseases
- Common causes and case investigation are discussed
- Respiratory anatomy and physiology of birds, reptiles, and amphibians are outlined
- Important objectives include understanding avian chlamydiosis, aspergillosis, and respiratory diseases of reptiles.
- Knowledge of investigative techniques for exotic patients (rabbits, rodents, ferrets) is also necessary. These topics can be found in mammalian lectures.
Avian Respiratory Diseases
- Chlamydiosis (Psittacosis):
- Caused by Chlamydia psittaci (obligate intracellular bacterium)
- Affects birds, especially cockatiels, budgerigars, and parrots
- Reportable and zoonotic (transmissible to humans)
- Transmission by fecal-oral or inhalation
- Acute and chronic (subclinical, latent) can be unmasked by stressors
- Clinical signs: nasal and ocular discharge, conjunctivitis, sinusitis, green-yellow feces, inactivity, fluffed, anorexia, weight loss
- Aspergillosis:
- Caused by Aspergillus fumigatus (common opportunistic environmental fungus)
- Commonly affects immunocompromised birds (poor environment, malnutrition, steroids)
- Especially parrots, raptors, waterfowl, and penguins
- Transmission by aerosolized spores (not bird to bird or zoonotic)
- Affects any part of the respiratory tract (can spread to liver, bone, kidneys, brain)
- Clinical signs: lethargy, anorexia, voice change, tachypnea, dyspnea, anorexia, weight loss
- Avian Flu (Orthomyxovirus):
- Caused by Orthomyxovirus (LPAI, HPAI)
- Primarily in aquatic/migratory birds
- High risk to commercial poultry and other birds, including mammals.
- Reportable, zoonotic
- Clinical signs: sudden death with no prior signs, lethargy, reduced appetite, purple discoloration of body parts, reduced egg production, soft-shelled/misshapen eggs, nasal discharge, coughing, sneezing, ataxia, diarrhea
Reptile Respiratory Diseases
- Important Bacterial Respiratory Pathogens:
- Mycoplasma, Mycobacterium, Pseudomonas, Salmonella, Chlamydia, E. coli, Klebsiella.
- Important Viral Respiratory Pathogens:
- Nidovirus/serpentovirus, Paramyxovirus, Reptarenavirus, Reovirus, Herpesvirus
- Important Mycotic Respiratory Pathogens:
- Candida, Paecilomyces, Aspergillus (opportunistic pathogens)
- Important Parasitic Respiratory Pathogens:
- Rhabdias, Strongyloides, Pentostomids, Renifers (rare in captive-bred reptiles)
Case Investigation
- History: Quarantine, recent additions, temperature, humidity, ventilation, air quality, malnutrition
- Physical Examination: Tachypnea (reduced non-ventilatory periods in reptiles), dyspnea (open mouth), nasal or glottal discharge, asymmetric swimming (aquatic turtles)
- Diagnostic Imaging: Radiography, CT
- Blood Collection and Testing: Hematology (infectious vs. non-infectious), biochemistry (rule out non-respiratory causes), serology (few)
- Definitive Diagnosis: Pathological process in animal, cytology, histopathology, paired rising titers AND demonstration of specific cause (culture, PCR, parasite identification, toxicology, paired rising titers)
- Resp. Tract Sample Collection: Nasal/choanal/tracheal swabs, lung lavage
- Endoscopy & Biopsy: Histopathology and culture for PCR
Medical Therapy
- Often 2-6 weeks for birds; 4-8 weeks for reptiles
- Drug choice dictated by test results and diagnosis, antibiotic, anti-fungal, anti-parasitic, anti-viral
- Supplemental fluids and nutrition are crucial
- Improvements in husbandry is needed
- Quarantine is essential.
