ABSTRACT
Protostrongylid nematodes are important lungworms of ruminants, especially Bovids. Its life cycle is participating terrestrial mollusсs as intermediate hosts. In this study, eight species of land mollusсs from Uzbekistan were found to be positive larvae of protostrongylids. Based on the nucleotide sequence data, three species of nematode larvae Protostrongylus rufescens, Muellerius capillaris, and Cystocaulus ocreatus were identified. According to the morphological characteristics of the studied land mollusсs, the shell structure was identified as six different morphotypes. After molecular genetics and morphological analyzes, these land molluscs belonged to 8 different species: Angiomphallia regeliana, Pseudonapaeus albiplicatus, P.maydanica, P. sogdiana, Psedonopaeus sp., Xeropicta candacharica, Deroceras reticulatum and Candaharia levanderi. The infection rate of Pulmonata snails by protostrongilids larvae was 28.2% and that of slugs - 6.8%. In addition, the first informs of P. maydanica, C. levanderi and D. reticulatum as natural intermediate hosts for M. capillaris are given.
