LLADA, Ignacio Mariano et al. Dictiocaulosis en vacas de cría en la provincia de Buenos Aires, Argentina: descripción de dos brotes. Analecta vet. [online]. 2020, vol.40, n.1, pp.25-25. ISSN 1514-2590.

Dictyocaulosis or parasitic bronchitis is caused by Dictyocaulus viviparus,a direct life cycle nematode, and is most frequently associated with clinical disease in young cattle during their first grazing season. This work describes two outbreaks of dictyocaulosis, in two cow-calf farms in Buenos Aires province, Argentina that caused the death of 13.6 and 15.7% of animals, respectively. In both outbreaks, clinical and pathological findings, and the presence of nematodes in respiratory tract, in some cases only observed in the histopathological analysis, allowed diagnosis confirmation.

Palabras clave : lungworm; parasitic bronchitis; bovine.
