“…Nos anos 50, com a utilização de uma vacina antiparasitária, e o desenvolvimento de novas drogas anti-helmínticas de amplo espectro na década de 70 e 80, a dictiocaulose foi considerada como uma "doença do passado". Porém, nos anos 90, ocorreram surtos de dictiocaulose e D. viviparus voltou a ser motivo de preocupação para a economia pecuária, como uma das principais enfermidades causadoras de perda da produtividade (3,4,5).…”

A dictiocaulose é uma afecção respiratória causada por helmintos do gênero Dictyocaulus spp., considerada potencial causa de queda na produtividade e morte de bovinos no Brasil e em outros países do mundo. Este trabalho descreve o relato de infecção por Dictyocaulus viviparus e dictiocaulose em bovinos no município de Londrina, PR. A associação das condições ambientais, nutricionais e imunológicas, juntamente com controle parasitário inadequado favoreceu o desenvolvimento da doença, ressaltando a importância da afecção como diagnóstico diferencial de doenças respiratórias dos bovinos na Região Sul do Brasil.

“…Occasional cases of husk have been reported in calves that have never been at grass and in housed cattle, possibly through acquiring infection soon after birth or from being fed cut grass or from limited cycling of infection in the bedding (Crawshaw and Smith, 2003). This article, the first of two, aims to complement and extend the review article previously published in Livestock (Tilling, 2014), initially with a focus on epidemiology, pathology and immunobiology, drawing on some of the seminal studies conducted over the last 65 years, linked with the results of some recent research on lungworm.…”

The bovine lungworm, Dictyocaulus viviparus, causes disease in all ages of cattle and in addition to having a self-evident effect on animal welfare, it can have a considerable economic impact at farm level, even with subclinical infections. Whilst most clinical cases are seen in cattle at pasture from July until housing, occasional outbreaks occur in housed cattle that have been infected previously at grass, or occasionally from infections acquired from forage or low-level cycling in straw yards. Whilst the overall seasonal pattern of infection is consistent over large temporal and spatial scales, there is marked year-to-year and within season variability in the number of cases seen at both regional and farm levels. This relative unpredictability can bring uncertainty to decisions on control. In order to be able to provide sound, evidence-based advice on treatment and control to farmers, it is important that clinicians grasp important, practically relevant aspects of lungworm biology, pathology, immunity and epidemiology: the aim of this article is to do just that. A second article describes and analyses the options for prevention and treatment of husk, based on this knowledge.
