“…The metastrongyloid Aelurostrongylus abstrusus (cat lungworm) is the most important in terms of its geographic distribution and role in respiratory diseases of domestic cats (Felis catus) (Traversa and Di Cesare 2013). This nematode also has been reported in wild felids, but most records have not been supported by valid microscopic or genetic evaluations (Traversa 2014).…”

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.

“…he so-called cat lungworm Aelurostrongylus abstrusus (Metastrongyloidea, Angiostrongylidae) parasitizes the respiratory system of cats in all corners of the world (1). 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).…”

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.

“…infestations in domestic cats. Various authors speculated that especially T. brevior infections might have been confused with A. abstrusus in the past due to the extremely similar morphological features of the L1 and the fact that diagnosis is routinely based on faecal examinations (Brianti et al 2012, Otranto et al 2013, Traversa and Di Cesare 2013. In fact, this is what has happened in the studies presented here.…”

The adulticidal efficacy of a topical combination of emodepside 2.1 % (w/v) plus praziquantel 8.6 % (w/v) (Profender ® spot-on for cats, Bayer) against adult Aelurostrongylus abstrusus nematodes was evaluated in two randomised, placebo-controlled laboratory efficacy studies. Each study involved 16 cats experimentally inoculated with L3 (800 and 600 each in studies no. 1 and 2, respectively) and randomised into two study groups of 8 cats each after onset of patency. While cats in the treatment group in study no. 1 received a single spot-on application at the minimum therapeutic dose (3 mg/kg emodepside and 12 mg/kg praziquantel), cats in study no. 2 were treated twice with an interval of 14 days. The faecal output of first stage larvae was monitored throughout the study. Necropsy was conducted 4 or 5 weeks after the (first) treatment and the worm counts were used for efficacy calculations. The control groups showed a geometric mean of the total worm count (live and dead worms) of 28.8 (study no. 1) and 17.6 (study no. 2), respectively. All control animals were infected. While the single treatment in study no. 1 resulted in a reduction of the total worm burden by 73.0 % (p = 0.0070), the treatment protocol in study no. 2 was 99.2 % effective (p = 0.0035). Based on live worm counts, the efficacy in study no. 2 was 100 % (p = 0.0030). It is concluded that two applications of Profender ® spot-on given two weeks apart represent a safe and highly efficacious treatment regime against feline aelurostrongylosis. S156EndoparasitEs
