Abstract
From 61 settlements of 12 Hungarian counties, 303 domestic cats were included in this survey. Between autumn 2016 and spring 2018, fresh faecal samples were randomly collected and examined by flotation and by the Baermann-Wetzel method for the presence of lungworm infection. No eggs of Eucoleus aerophilus were detected. Morphological identification of first instar larvae (L1) was also carried out. In the faeces of 60 cats (19.8%) from 17 settlements and Budapest, L1 of Aelurostrongylus abstrusus were found. More than half of the cats were from the western part of the country. The average number of larvae per gram of faeces was 190.2 ± 304.88. These results are in line with the former findings on the prevalence of aelurostrongylosis of domestic cats in Hungary. In addition, Oslerus rostratus was also found for the first time in the faecal samples of three cats from the eastern part of the country, infected also with Ae. abstrusus. The average age (2.51 ± 1.26 years) of infected cats indicates that lungworm infection is more common among younger cats. No relationship was found between the lung-worm infection and the sex of cats. Non-neutered cats had a significantly higher proportion of lungworm infections. Two-thirds of the infected cats were apparently healthy, and only 19 individuals showed clinical signs of respiratory disorders.

All infected cats belonged to the European shorthaired breed, most of them (47/60, 78.33%; 95% CI: 66.38–86.87) lived outdoors, and 11 (18.33%; 95% CI: 10.56–29.92) stayed both indoors and outdoors
Summary
From 61 settlements of 12 Hungarian counties, 303 domestic cats were included in this survey. The average number of larvae per gram of faeces was 190.2 ± 304.88 These results are in line with the former findings on the prevalence of aelurostrongylosis of domestic cats in Hungary. Oslerus rostratus was found for the first time in the faecal samples of three cats from the eastern part of the country, infected with Ae. abstrusus. Lungworm infection of domestic and wild cats occurs in many countries around the world. It is most commonly caused by Aelurostrongylus abstrusus, Railliet, 1898 (Strongylida, Angiostrongylidae), called the cat lungworm (Anderson, 2000; Bowman, 2000). Other lungworm species of domestic cats such as Troglostrongylus brevior and T. subcrenatus (Strongylida, Crenosomatidae), Oslerus rostratus Cats can be infected by intermediate hosts or various other animals
