Research Article Some Pathological Features of Lungs from Domestic and Wild Ruminants with Single and Mixed Protostrongylid Infections
2013Co-Authors: Mariana Panayotova-pencheva, Marin Tsvyatkov AlexAbstract:Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Lungs of 40 ruminants from Bulgaria with natural small lungworm (Nematoda: Protostrongylidae) infections were investigated, including 16 goats, 15 sheep, 7 mouflons, and 2 chamois. Muellerius capillaris, M. tenuispiculatus, Cystocaulus ocreatus, Neostrongylus linearis, and Protostrongylus brevispiculum infections were predominantly associated with nodular lesions, and Protostrongylus rufescens, Protostrongylus hobmaieri and Protostrongylus rupicaprae were associated with extensive lesions located mainly along the length of the large bronchi. The extent of lung abnormalities was most severe in the sheep. Alveolitis, parasite granulomas, damage of the alveolar septa, hyperplasia of the lung associated lymphoid tissue, and sclerosis of the parenchyma were found upon microscope examinations. In the goats compared to the sheep and mouflons, the terminal bronchi, bronchioles, and alveoli were more affected than the interstitium. Our research shows that the pathological lesions in the lungs of ruminants infected with protostrongylids depend on both the helminth and the host species. To our knowledge, this work is the first to provide data on the pathomorphological lesions in mouflon lungs infected with protostrongylids. 1

Species composition and morphology of protostrongylids (Nematoda: Protostrongylidae) in ruminants from Bulgaria
Parasitology Research, 2011Co-Authors: Mariana Panayotova-penchevaAbstract:Lungs of 52 ruminants from different regions of Bulgaria, 16 from goats ( Capra aegagrus f. domestica L.), 15 from sheep ( Ovis ammon f. domestica L.), 11 from mouflons ( Ovis musimon L.), and 10 from chamois ( Rupicapra rupicapra L.), were investigated. The aim of the study was to determine the species composition of small lungworms in these hosts. The obtained results are summarized with those of previous studies, and a picture of the present status of the species composition of protostrongylids in ruminants from Bulgaria is forwarded. Morphometric data about the species Muellerius capillaris , Cystocaulus ocreatus , Neostrongylus linearis , Protostrongylus brevispiculum , and Protostrongylus rufescens are presented. The data on the morphology of these five species are supplied for the first time both for Bulgaria and the south-east part of the European continent.

Morphological data on two protostrongylid species, etiological agents of pulmonary helminthoses in wild ruminants (materials from Bulgaria)
European Journal of Wildlife Research, 2008Co-Authors: Mariana Panayotova-penchevaAbstract:Description of the morphology of Protostrongylus rupicaprae and Varestrongylus sagittatus (Nematoda: Protostrongylidae) on materials from Bulgaria are presented. The specimens of P. rupicaprae were obtained from a chamois from the wildlife-breeding station “Izvora” in the Rhodope Mountains and those of V. sagittatus from red deer from the wildlife-breeding station “Vitinya” in the Balkan Mountains. The present data were compared with those of the same species indicated by other authors on materials from West and Central Europe and Southwest Asia. This is the first description of the morphology of these two helminth species on materials from the southeast part of the European continent.

intermediate hosts of Protostrongylus pulmonalis frolich 1802 and p oryctolagi babos 1955 under natural conditions in france
Parasites & Vectors, 2015Co-Authors: Célia Lesage, Cécile Patrelle, Anouk Decors, Hubert Ferté, Sylvain Vrignaud, Damien JouetAbstract:Background Protostrongylus oryctolagi and P. pulmonalis are causative agents of pulmonary protostrongyliasis in Lagomorphs in France. These nematodes need usually one intermediate host for its life cycle, a terrestrial snail. However, some studies, mainly in experimental conditions, have identified the species of snails acting as intermediate hosts.

Protostrongylus pulmonalis (Frölich, 1802) and P. oryctolagi Baboš, 1955 (Nematoda: Protostrongylidae), parasites of the lungs of European hare (Lepus europaeus L.) in France: morphological and molecular approaches
Parasitology Research, 2014Co-Authors: Célia Lesage, Damien Jouet, Cécile Patrelle, Jean-sébastien Guitton, Anouk Decors, Hubert FertéAbstract:Pulmonary protostrongyliasis of hare is a parasitic disease caused by nematodes belonging to the genus Protostrongylus (Nematoda, Protostrongylidae). During survey of wildlife disease in the South-East of France, pathologic examination of lungs from European hares found dead or hunter-killed between 2009 and 2012 was performed. Adult male worms were morphologically characterized and the identification confirmed by molecular biology (D2 domain of the 28S and ITS2 of rDNA). Two different species were identified: the first one, Protostrongylus pulmonalis , is identical with the haplotype previously deposited in GenBank. Based on morphological criteria of copulatory bursa of adult male worms (especially length of spicules and gubernaculum structure), we identified a second species found in France as Protostrongylus oryctolagi. This is the first report of P. oryctolagi in France from European hare and rabbit. P. oryctolagi was isolated from 248 hares and 3 rabbits in the South of France. P. pulmonalis was isolated from four hares found dead in the Northern France and from one hare in the South, which was co-parasitized by P. oryctolagi and P. pulmonalis . It’s the first coinfection observed with these two species from a lung of hare in France.

The mitochondrial genome of Protostrongylus rufescens – implications for population and systematic studies
Parasites & Vectors, 2013Co-Authors: Abdul Jabbar, Namitha Mohandas, Aaron R Jex, Robin B GasserAbstract:Background Protostrongylus rufescens is a metastrongyloid nematode of small ruminants, such as sheep and goats, causing protostrongylosis. In spite of its importance, the ecology and epidemiology of this parasite are not entirely understood. In addition, genetic data are scant for P. rufescens and related metastrongyloids. Methods The mt genome was amplified from a single adult worm of P. rufescens (from sheep) by long-PCR, sequenced using 454-technology and annotated using bioinformatic tools. Amino acid sequences inferred from individual genes of the mt genomes were concatenated and subjected to phylogenetic analysis using Bayesian inference. Results The circular mitochondrial genome was 13,619 bp in length and contained two ribosomal RNA, 12 protein-coding and 22 transfer RNA genes, consistent with nematodes of the order Strongylida for which mt genomes have been determined. Phylogenetic analysis of the concatenated amino acid sequence data for the 12 mt proteins showed that P. rufescens was closely related to Aelurostrongylus abstrusus , Angiostrongylus vasorum , Angiostrongylus cantonensis and Angiostrongylus costaricensis . Conclusions The mt genome determined herein provides a source of markers for future investigations of P. rufescens . Molecular tools, employing such mt markers, are likely to find applicability in studies of the population biology of this parasite and the systematics of lungworms.
