Aspergillus fumigatus infection in two wild Eurasian black vultures (Aegypius monachus Linnaeus) with carbofuran insecticide poisoning: a case report.
Aspergillus spp. are opportunistic pathogens which cause pulmonary aspergillosis in animals and humans with compromised immune systems. Two Eurasian black vultures (Aegypius monachus Linnaeus) were found dead or clinically ill from carbofuran insecticide during the winter of 2004. Carbofuran was detected in the stomach contents by gas chromatograph-mass spectrometry. Gross lesions showed severe granulomatous pneumonia and serofibrinous pleuropneumonia in both birds, with most lesions restricted to the pulmonary system. Histological lesions included pyogranulomatous pneumonia and suppurative parabronchiolitis/pleuritis/air sacculitis with a number of septated fungal hyphae, suggesting severe pulmonary aspergillosis. Fungal isolates from each vulture were identified as Aspergillus fumigatus by both lactophenol cotton blue staining and genetic analysis. This is the first report of pulmonary aspergillosis caused by A. fumigatus in wild Eurasian black vultures and suggests that Aspergillus infection could be an important cause of death in these birds which migrate from Mongolia to Korea during the winter. The incidence of the disease may be related to impaired immunity caused directly or indirectly by carbofuran poisoning.
