Overview of helminths in small mammals in the Zhiguli State Reserve

Abstract

Поступила в редакцию: 09.02.2017На территории Жигулевского заповедника изучена гельминтофауна 24 видов мелких млекопитающих (от-ряды Insectivora, Chiroptera, Rodentia). У микромаммалий отмечено 90 видов паразитов: Trematoda -24, Cestoidea -21, Nematoda -43 и Acanthocephala -2. Для каждого вида гельминтов указывается систематиче-ское положение, локализация, круг хозяев, место обнаружения, специфичность к хозяевам, географическое распространение. Наиболее богатой в видовом отношении гельминтофауной обладают грызуны, у которых зарегистрировано 33 вида паразитов. У рукокрылых отмечено 32 вида гельминтов; у насекомоядных -28 видов. Общим для всех трех отрядов млекопитающих является только один вид паразитов -скребень . В Волжском бассейне у мелких млекопитающих впервые найден 21 вид па-разитических червей. Из 90 видов гельминтов, зарегистрированных у микромаммалий Жигулевского запо-ведника, 9 имеют эпидемиологическое и эпизоотологическое значение.

Helminths in Myomorph Rodents (Rodentia, Myomorpha) from the National Park “Smolny” and Its Surroundings (European Russia)

“…We have not found in small rodents of the National Park "Smolny" a dangerous parasite the metacestode Echinococcus multilocularis Leuckart, 1863, which causes echinococcosis of humans and animals [75,76]. Despite the widespread distribution of E. multilocularis in the northern and central regions of Eurasia in the final hosts-carnivores [48,75], single findings of the parasite in M. arvalis and A. agrarius from the Samarskaya Luka (Middle Volga region) were recorded in rodents of European Russia [27,28,77].…”

“…Despite the relatively high helminth diversity observed in the myomorph rodents from the National Park "Smolny", it still does not reach its maximum, since more than 80 species of parasitic worms are known for small wild rodents in European Russia [9,[27][28][29][30][31][32][33][34]45,77,[86][87][88]. Thus, we have registered 39 helminth species in the myomorph rodents from the Samarskaya Luka, located 300 km south-east [27,28,34,77]. In Karelia, 35 species of helminths were identified in small rodents [45,87].…”

“…Considering that full-scale helminthological studies of vertebrates in the National Park "Smolny" have not previously been carried out, the trend of parasitological research associated with the inventory of animal helminth fauna as one of the stages of the inventory of the fauna of protected areas, monitoring and preserving biological diversity is relevant [9,[27][28][29][30][31][32][33][34].…”

Occurrence of the insectivores and rodents in the Samarskaya Luka (European Russia)

“…The coordinate reference to each mammal occurrence record is given for the first time in the dataset. The major part of the dataset was obtained during our helminthological study of small mammals in Samarskaya Luka ( Kirillova and Kirillov 2008 , Kirillova and Kirillov 2009 , Kirillova and Kirillov 2011 , Kirillova and Kirillov 2017 , Kirillova 2010 , Kirillova 2011 ). Besides, some data were obtained when studying the ecology of Glis glis and another tree-dwelling rodent species ( Ivashkina 2006 , Vekhnik 2017 , Vekhnik 2019 , Vekhnik 2020 , Vekhnik and Vekhnik 2017 , Vekhnik and Vekhnik 2018 ).…”

“…The basis for our dataset was our trapping of small mammals during the study of the helminth fauna of insectivores and rodents in Samarskaya Luka in the period 2000–2020 ( Kirillova and Kirillov 2008 , Kirillova and Kirillov 2009 , Kirillova and Kirillov 2011 , Kirillova and Kirillov 2017 , Kirillova 2010 , Kirillova 2011 ). Another component of the dataset was a long-term study of the biology of tree-dwelling species in the Zhiguli State Nature Reserve and its surroundings.…”
