An update of lungworm infection in cat with especial reference to aelurostrongylosis

Abstract

Aelurostrongylus abstrusus, the most prevalent species affecting the respiratory system of domestic cats is transmitted through the ingestion of gastropod intermediate or paratenic hosts. The most pathogenic significance is formation of nodules by the masses of eggs and larvae in the alveoli and terminal bronchioles, with fewer adult worms. Clinical signs of lungworm infection range from moderate coughing with slightly increased breathing rates to severe, persistent coughing, labored breathing, and respiratory distress or failure. Coughing and weight loss and, sometimes, severe dyspnoea and death, particularly if there are secondary bacterial infections are the main clinical intervention of chronic respiratory disease. Confirmation of first-stage larvae in the faeces may be the main diagnostic approach. Epidemiological studies may be help in treatment and control of the lungworm infection in cats. Treatment with levamisole, albendazole and fenbendazole has the value in cats.
