“…A similar finding was observed in both naturally and experimentally infected cats in the so-called "regressive stage" of O. rostratus infection, in which worms are encapsulated by a fibrous tissue capsule surrounded by a great accumulation of leucocytes (Seneviratna 1958). This strong fibrous reaction may explain the reason why any larvae were detected in the faeces of the infected animal, even if female worms were filled with L1s in the uterus.…”

“…Unfortunately, because of the stray condition and of the sudden death of the animal, it was not possible to collect data on the presence of clinical signs associated with the infection. However, since no plugs of mucous were detected around the nose or in the lumen of trachea and bronchi at the necropsy, the animal had most likely a normal breathing, as previously observed in both natural and experimental infected cats (Seneviratna 1958). Since O. rostraus lives in the peri-bronchial tissues and in the bronchial walls, the lesions it causes are different from those of other worms that live in the bronchial lumen (i.e.…”

“…Contrarily to A. abstrusus and T. brevior which are frequently found in young kittens , also as an effect of the potential vertical transmission of the latter species , O. rostratus infection has never been diagnosed in cats younger than 6 months of age (Seneviratna 1958), likely as an effect of the long prepatent period (about 78 days) (Seneviratna 1958). Accordingly, the case here reported was a 4-year-old cat.…”

Feline lungworm Oslerus rostratus (Strongylida: Filaridae) in Italy: first case report and histopathological findings

Oslerus rostratus syn. Anafilaroides rostratus (Strongylida: Filaroididae) is a metastrongyloid transmitted by snails, which localizes in peri-bronchial tissues and in the lung parenchyma of wild as well as domestic cats. In Europe, this nematode has been reported only on two occasions, being diagnosed in cats from Majorca Island and in northern Spain. Here, we describe a case of O. rostratus infection in a necropsied 4-year-old cat in Sicily (southern Italy). At the inspection of lungs, slender and greyish nematodes (four females and two males) were found embedded in the peri-bronchial tissues and in the bronchial walls. Parasites were morphological and molecularly identified as O. rostratus, with their 18S sequences being identical among them and showing a high homology (99%) with those available in public databases. At the histology, nematodes were encapsulated in a pseudo-cystic formation surrounded by an interstitial inflammatory process and fibrous tissue. Lung lesions were mainly represented by peri-luminal fibrosis, hyperplasia and hypertrophy of the bronchial mucosa and glands, respectively. This first record of O. rostratus infection from Italy indicates that this parasite should be included in the differential diagnosis of feline of lungworm infection.

“…According to the literature, this parasite is far less common than the other cat's lung nematode, Aerulostrongylus abstrusus, including the Iberian Peninsula (PayoPuente et al 2008). Oslerus rostratus was first described from a cat in Palestine (Gerichter 1949) and it was shown to be frequent in cats from Sri Lanka (60%, Seneviratna 1958) and in bobcats (Lynx rufus) from the USA (Klewer 1958;Watson et al 1981). It has been also detected in Hawaii (Ash 1962) and in a cat from northern Spain (Juste et al 1992).…”

High prevalence of helminth parasites in feral cats in Majorca Island (Spain)

Feral cats are widespread in the countryside of Majorca (Balearic Islands, Spain). Since they are not subject of sanitary control, they can act as reservoir of parasites of veterinary and zoonotic interest. The main organs of 58 wild-trapped cats in 16 different areas from Majorca were analyzed by helminths. All the cats were parasitized, and eight species of helminths were retrieved (mean = 3.4 species per cat, with 74% of the cats harboring three or more species). Seven of them presented a prevalence >20%: Joyeuxiella pasqualei (76%), Diplopylidium acanthotetra (60%), Dipylidium carracidoi (33%), Taenia taeniaeformis (22%), Ancylostoma tubaeforme (91%), and Toxocara cati (35%) in the gastrointestinal tract, and Oslerus rostratus (24%) in lungs. The A. tubaeforme prevalence and intensity (mean = 30, up to 396) is the highest recorded for a population of cats. Prevalence and abundance of J. pasqualei and D. acanthotetra were strongly associated, secondary to the use of the same intermediary host (geckos). Other positive associations found are probably related to host susceptibility. Abundance of D. acanthotetra, T. cati, and A. tubaeforme and the number of species per host were negatively correlated with cat body condition (assessed by the kidney fat index). Females were more frequently parasitized by A. tubaeforme than males, and adult females were more heavily infested by J. pasqualei and D. acanthotetra than cats from other groups. These and other findings are discussed in relation with host ecology. Feral cats serve as reservoirs of helminths in the countryside of Majorca and their populations should be controlled.

“…Although adults of A. abstrusus, T. brevior and O. rostratus are morphologically distinct and characterised by different localizations in the lungs of cats, first-stage larvae retrieved in the faeces of the hosts are morphometrically similar, thus complicating its diagnosis . In addition, diagnosis may be further complicated by the presence of the so-called "regressive stage" of O. rostratus infection, in which worms are encapsulated by pseudo-cystic formations surrounded by inflammatory cells and fibrotic tissue reactions (Seneviratna, 1958;Brianti et al, 2014) which, in turn, results in the absence of larvae in the faeces of affected animals. Therefore, in cases of co-infections by A. abstrusus and O. rostratus, only L1s of A. abstrusus are likely to be detected in the faeces of the infected cat, while O. rostratus is only seen upon necropsy (Juste et al, 1992;Brianti et al, 2014).…”
