Fatal pulmonary strongyloidiasis in a dog: clinical implications and first molecular identification in Chile

Key Points

• To report the clinical implications of fatal pulmonary strongyloidiasis in a dog and to document the first molecular identification in Chile.
• Clinical observation of a six-month-old male Pomeranian with respiratory issues.
• Diagnostic imaging and bronchoalveolar lavage (BAL) for larval identification.
• PCR and sequencing used to confirm the species of the larvae.
• Severe pulmonary edema was diagnosed via imaging.
• Nematode larvae were found in BAL analysis.
• Strongyloides stercoralis was confirmed through PCR and sequencing.
