Паразиты дальневосточного леопарда (Panthera pardus orientalis) на юго-западе Приморского края России

The results of long-term studies of invasions of the Panthera pardus orientalis, Schlegel 1857. The study of parasitic invasions of the Far Eastern leopard was carried out by two methods. The first method included the study of excrement of the Far Eastern leopard collected in different seasons of the year from January 2009 to December 2014 by the Kotelnikov-Khrenov method. The second method is a complete parasitologic autopsy on Scriabin, the dead animals on the basis of PGHS. The autopsy was conducted by the chief veterinarian of the Primorsky Krai, and the autopsy report was compiled. To analyze the data obtained, the indicator was used - the index of occurrence, expressed as a percentage. As a result, the species composition of helminths parasitizing the Far Eastern leopard is supplemented by species of nematodes - Ancylostoma sp., Gnathostoma spinigerum Capillaria sp., Dirofilaria sp; cestodes - Taenia sp., Dipylidium caninum, Spirometra erinaceieuropei, Mesocestoides lineatus; trematodes - Nanophyetus salmicola schikhobalowi, Clonorchis sinensis, Metagonimus yokogawa. Dominiruet monoinvasion (66,6%). Di-invasion and triinvasia are much less common - 17,7% and 4,4%. Of the protozoans, oocysts were found isospora rivolta. On the body of the dead animals were found ixodid mites - Haemaphysalis flava, Haemaphysalis longicornis, Haemaphysalis japonica douglasi, Haemaphysalis punctate. It indicates the presence in the excrement of fleas of genus Ctenocephala и клещей рода and mites of the genus Otodectes.Цель исследования - выявить экто- и эндопаразитов дальневосточного леопарда (Panthera pardus orientalis, Schlegel 1857). Материалы и методы. Изучение паразитарных инвазий дальневосточного леопарда проводили двумя методами. Первый метод включал исследование фекалий дальневосточного леопарда, собранных в разные сезоны года с января 2009 г. по декабрь 2014 г. методом Котельникова-Хренова. Второй метод включал полное гельминтологическое вскрытие по Скрябину погибших животных на базе Приморской государственной сельскохозяйственной академии. Вскрытие проводили главным ветеринарным врачом Приморского края; составлен протокол вскрытия. Собранных паразитов фиксировали и обрабатывали стандартными методиками. Определение вида клещей проводили по определителю Н. A. Филипповой (1997). Для анализа полученных данных использовали показатель - индекс встречаемости, выраженный в процентах. Результаты и обсуждение. Видовой состав гельминтов, паразитирующих у дальневосточного леопарда, дополнен видами нематод - Ancylostoma sp., Gnathostoma spinigerum, Capillaria sp., Dirofilaria sp; цестод - Taenia sp., Dipylidium caninum, Spirometra erinaceieuropei, Mesocestoides lineatus; трематод - Nanophyetus salmicola schikhobalowi, Clonorchis sinensis, Metagonimus yokogawa. Доминирует моноинвазия (66,6 %). Дииинвазия и триинвазия наблюдаются гораздо реже - 17,7 и 4,4 % соответственно. Из простейших были обнаружены ооцисты Isospora rivolta. На теле погибших животных были найдены иксодовые клещи Haemaphysalis flava, H. longicornis, H. japonica douglasi, H. punctate. Указывается на нахождение в фекалиях блох рода Ctenocephala и клещей рода Оtodectes

Exploring the utility of cross-laboratory RAD-sequencing datasets for phylogenetic analysis

BACKGROUND: Restriction site-Associated DNA sequencing (RAD-Seq) is widely applied to generate genome-wide sequence and genetic marker datasets. RAD-Seq has been extensively utilised, both at the population level and across species, for example in the construction of phylogenetic trees. However, the consistency of RAD-Seq data generated in different laboratories, and the potential use of cross-species orthologous RAD loci in the estimation of genetic relationships, have not been widely investigated. This study describes the use of SbfI RAD-Seq data for the estimation of evolutionary relationships amongst ten teleost fish species, using previously established phylogeny as a benchmark. RESULTS: The number of orthologous SbfI RAD loci identified decreased with increasing evolutionary distance between the species, with several thousand loci conserved across five salmonid species (divergence ~50 MY), and several hundred conserved across the more distantly related teleost species (divergence ~100–360 MY). The majority (>70%) of loci identified between the more distantly related species were genic in origin, suggesting that the bias of SbfI towards genic regions is useful for identifying distant orthologs. Interspecific single nucleotide variants at each orthologous RAD locus were identified. Evolutionary relationships estimated using concatenated sequences of interspecific variants were congruent with previously published phylogenies, even for distantly (divergence up to ~360 MY) related species. CONCLUSION: Overall, this study has demonstrated that orthologous SbfI RAD loci can be identified across closely and distantly related species. This has positive implications for the repeatability of SbfI RAD-Seq and its potential to address research questions beyond the scope of the original studies. Furthermore, the concordance in tree topologies and relationships estimated in this study with published teleost phylogenies suggests that similar meta-datasets could be utilised in the prediction of evolutionary relationships across populations and species with readily available RAD-Seq datasets, but for which relationships remain uncharacterised.
