ABSTRACT. In September of 2017, two orphaned juvenile black bear cubs in a captive rehabilitation facility presented with clinical signs of coughing and cyanosis. Within days, nine of nine cohoused bears were exhibiting dyspnea, coughing, and lethargy. Despite therapeutic intervention, two bears died and were submitted to the Wisconsin Veterinary Diagnostic Laboratory for necropsy. Gross and microscopic findings were consistent with severe catarrhal and eosinophilic tracheitis and bronchopneumonia caused by a nematode parasite. Molecular identification of the parasite Capillaria aerophilus was confirmed by semi-nested PCR targeting the Cox1NEM and CaerInt2F genes. Numerous eggs morphologically consistent with C. aerophilus were detected by fecal examination of both bears. Anthelminthic treatment of the remaining cohoused bears led to resolution of clinical signs. A number of wild carnivores can serve as definitive hosts of C. aerophilus, including black bears. Dogs and cats may also become infected, and there are rare reports in humans. Capillaria aerophilus has a direct life cycle, although earthworms can act as paratenic hosts.  While there is a single description of C. aerophilus-associated bronchopneumonia in wild black bears, this parasite has not been previously associated with an outbreak or fatalities in this species.
