“…Then, it remained practically unknown until the past 2 yr, when it was isolated in two domestic cats: one from Sardinia, Italy , and one from the Umbria region of central Italy (Traversa et al 2015), the same region from which the wildcat infected in this study was obtained. In addition, this latter cat was also infected by T. brevior and A. abstrusus (Traversa et al 2015). Further studies are warranted to evaluate the occurrence of the apparently rare A. chabaudi in wild and domestic felids from Italy and elsewhere.…”

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.

“…Moreover, three nematodes were found in the pulmonary arteries of this latter wildcat, but their poor condition allowed only a microscopic identification as Angiostrongylus sp. ; nonetheless, they were identified as Angiostrongylus chabaudi based on genetic data (Traversa et al 2015).…”

“…26,27 Very recently, a triplex semi-nested PCR has been validated for the simultaneous discrimination of A abstrusus, T brevior and Angiostrongylus chabaudi; 74 the last is a very rare cardiopulmonary nematode of wild felids that has been recorded in a mixed infection with lungworms in a domestic cat. 75 All of these recently developed molecular assays have proved powerful for the diagnosis of feline aelurostrongylosis and troglostrongylosis, overcoming the constraints of classical diagnosis. The PCR assay specific for A abstrusus was validated on a panel of faecal (ie, faeces, flotation supernatant, Baermann sediment) and pharyngeal swab samples from infected cats.…”

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.

“…In the past few years, another respiratory metastrongyloid, Troglostrongylus brevior (Metastrongyloidea, Crenosomatidae), previously described over the last century in wild felids from the Middle East, has been recorded in domestic cats from Mediterranean Europe (1,2). Recently, the almost unknown heartworm Angiostrongylus chabaudi (Metastrongyloidea, Angiostrongylidae), recorded only in the last century in wildcats until recently (3), has been found in two domestic cats from Italy (4,5).…”

Feline lungworms and heartworms are stimulating the interest of the scientific community due to their clinical impact and apparent geographical expansion. Diagnosis of the infections caused by these nematodes is indeed challenging. This report describes a novel multiplex PCR able to identify simultaneously three species of lungworms (Aelurostrongylus abstrusus and Troglostrongylus brevior) and heartworms (Angiostrongylus chabaudi) affecting felids. Epidemiological and clinical perspectives are discussed.
