“…In several cases, affected animals can be reported dead with few or no previous signs (ERICKSON & DOSTER, 1993). In more chronic cases, submucosal fibrosis can be observed in the trachea (ERICKSON & DOSTER, 1993). This study aimed to describe the epidemiological, clinical and pathological aspects of a case of tracheal stenosis in a Holstein cow, which in the authors' knowledge, is the first description of this disease in this bovine breed and the first description of the disease in South America.…”

“…Tracheal stenosis, also known as tracheal edema and hemorrhage syndrome, was described in confined cattle (ERICKSON & DOSTER, 1993;GAGEA et al, 2006;HENDRICK & ABEYSEKARA, 2014) and recently in finishing pigs (SZEREDI et al, 2015). The disease is characterized by a partial obstruction of the tracheal lumen due to severe edema and mucosal and submucosal hemorrhage of the dorsal distal half of the trachea (CASWELL & WILLIAMS, 2016;CLARK, 2004).…”

“…The disease is characterized by a partial obstruction of the tracheal lumen due to severe edema and mucosal and submucosal hemorrhage of the dorsal distal half of the trachea (CASWELL & WILLIAMS, 2016;CLARK, 2004). Its etiology remains uncertain; however, it is attributed to noninfectious causes (ERICKSON & DOSTER, 1993;CLARK, 2004). There was also no association of tracheal stenosis in confined cattle with other preexisting chronic airway or lung lesions.…”

“…There was also no association of tracheal stenosis in confined cattle with other preexisting chronic airway or lung lesions. This disease is commonly associated with extenuating activities in heavy animals, in a dusty environment and hot weather (ERICKSON & DOSTER, 1993;APLEY & FAIT, 1998).…”

“…The respiratory stridor produced by severely affected animals originates from the clinical term of "Honker syndrome". In several cases, affected animals can be reported dead with few or no previous signs (ERICKSON & DOSTER, 1993). In more chronic cases, submucosal fibrosis can be observed in the trachea (ERICKSON & DOSTER, 1993).…”

Tracheal stenosis, also known as “Honker syndrome”, is characterized by tracheal edema and hemorrhage, leading to partial obstruction of the lumen; therefore, death. Its etiology is not yet well elucidated. A 3-year-old Holstein cow, with a history of dyspnea, and a large amount of reddish foam flowing from the mouth and nose, had died after 10 minutes of clinical signs. Macroscopic examination revealed focally extensive hemorrhage and clot organization in tracheal mucosa extending to the submucosa, surrounded by well-differentiated fibrous connective tissue. In adjacent mucosa was observed moderate multifocal inflammatory infiltrate composed by lymphocytes and plasma cells, as well as moderate squamous cell metaplasia. The bacterial culture showed growth of contaminant and environmental bacteria and the RT-PCR to detect Herpesvirus 1 (BoHV-1) and 5 (BoHV-5) was negative. To the author’s knowledge, this is the first report of tracheal stenosis in South America, as well as the first report of this condition described in a Holstein cow.
