“…The data from literature confirms that quite frequently in cats the lack of typical symptoms is noted (28). The respiratory signs are often observed in young, debilitated and immunosuppressed cats and are connected with a disorder of the respiratory system (29).…”

The data on the invasion of Aelurostrongylus abstrusus in domestic cats is limited, both for Europe and for the rest of the world. The diagnosis is difficult and the invasion is often not considered in the differential diagnosis of respiratory diseases. Consequently, this invasion is diagnosed late and leads to the death or euthanasia of the animals as the infection is usually asymptomatic. During an intensive invasion, symptoms of the respiratory system disorders and sometimes diarrhoea and anorexia may be observed. A 7 year-old cat, treated in a veterinary clinic in Poland showed the signs of a chronic cough, shortness of breath, nasal mucopurulent discharge, accelerated breathing and a loss of appetite. The first diagnosis was pneumonia. Additionally, parasitological examination was used by a standard flotation technique and decantation method. The flotation test result was negative, the decantation method revealed the presence of one A. abstrusus larva. In order to confirm the diagnosis we used the Baermann’s method. The result was positive, larvae were counted and identified basing on their morphology and morphometry, which demonstrated numerous L1 larvae of A. abstrusus. Aside from the symptomatic treatment, a causal cure using a combination of 10% imidacloprid and moxidectin 1% spot-on was applied. The control examination of faecal samples was performed using the Baermann’s method 7, 14, 30 and 60 days after therapy. One and two weeks after the treatment had found larvae, whereas no larvae were found 30 days and 60 days after therapy. The health status of the cat began to return to normal. A parasitology examination performed 6 months after the completion of treatment failed to confirm the presence of A. abstrusus larvae . The cat is under constant medical supervision and in spite of recurrent symptoms its health state is stable.

Practical relevance: Respiratory parasites infecting domestic cats are attracting increased attention in feline clinical practice. In addition to the most commonly recognised 'cat lungworm' Aelurostrongylus abstrusus, Troglostrongylus brevior and Capillaria aerophila are now considered important pathogens of the respiratory tract of cats. Global importance: These parasites are being increasingly diagnosed in several regions of the world and a continuous update on epidemiological changes and advances in diagnosis and control is of practical importance. Aims: This article reviews current knowledge of lungworms affecting cats, with a special focus on recent insights into diagnosis and management of the diseases they cause. The article also explores some potential new avenues for control of feline parasitic respiratory diseases, and highlights some key areas requiring further research.

“…This knowledge gap is important from an epizootiologic viewpoint, given that wildcat populations in the central region occur at relatively high densities (Ragni 2006;). In addition, coastal areas and Apennine territories of central Italy have the highest number of single clinical cases and prevalence of cat lungworms in Europe (Traversa et al 2008(Traversa et al , 2009Di Cesare et al 2011.…”

The increasing focus on infections in domestic cats (Felis catus) has raised questions about lungworm distribution in wild hosts. To enhance knowledge of the occurrence of lungworms in enzootic regions of central Italy, we examined the carcasses of 16 European wildcats (Felis silvestris silvestris). Adult nematodes, feces, respiratory flushings, and pulmonary tissues were collected at necropsy and then microscopically and genetically analyzed. Fourteen wildcats had single or mixed lungworm species. Aelurostrongylus abstrusus was the most common parasite retrieved, followed by Troglostrongylus brevior. In addition, three specimens of Angiostrongylus chabaudi were found in the pulmonary arteries of one wildcat. Histologically, the most common lesions were a mild-to-severe chronic catarrhal bronchitis and a chronic interstitial pneumonia with smooth muscle hypertrophy, associated with T. brevior and A. abstrusus, respectively. These results demonstrate that the European wildcats may harbor several species of lungworms that may impair their health and welfare. Also, F. s. silvestris is a potential reservoir for respiratory nematodes in domestic cats.
