Research into various bacterial pathogens that can be transmitted between different animals and may have zoonotic potential has led to the discovery of different strains of Bartonella sp. in bats and their associated ectoparasites. Despite their enormous species diversity, only a few studies have focussed on the detection of bacterial pathogens in...

Also we curate previously known data and registered new host-parasite associations for species belongin...

The Caucasus is a large region in Eurasia consisting of four countries: Russia, Georgia, Azerbaijan, and Armenia. Although it is one of the biodiversity hotspots in the world, the bat ectoparasite fauna has been poorly studied. To promotionally fill in the gaps regarding bat ectoparasites, we conducted five field surveys on bats and their ectoparas...

Here, we present new geographic and host records of spinturnicid mites collected from alcohol-preserved bats at the Zoological Museum of Moscow State University, Russia. The new host records are Eyndhovenia euryalis cornuti on the eastern long-fingered bat Myotis macrodactylus and Spinturnix myoti on Rickett's big-footed bat Myotis pilosus. Spintur...

The parasitic spinturnicid mite Spinturnix psi was found on alcohol-preserved museum specimens of the common bent-wing bat Miniopterus schreibersii from Crimea. This is a case of a local host-parasite co-extinction since the Crimean population of this bat was exterminated in the middle of 20th century and the parasite does not inhabit other bat spe...

Conservation genetics is important in the management of endangered species, helping to understand their connectivity and long‐term viability, thus identifying populations of importance for conservation. The pond bat (Myotis dasycneme) is a rare species classified as “Near Threatened” with a wide but patchy Palearctic distribution. A total of 277 sa...

Parasitism is a widespread life-history strategy in nature. Despite the abundance of parasitic species, many aspects of their biology (e.g., population parameters, vulnerability degree, extinction possibility, and the need for protection) remain understudied. Parasites are perceived negatively (even by some scientists). This results in the underapp...

The order Chiroptera comprises more than 1.300 species that are hosts for more than 1.000 species of ticks and mites and of about 700 insect species; many of these parasites are involved in circulation of numerous pathogens. The present paper presents the first and most complicated review of literature on pathogens associated with bat ectoparasites...

Specimens archived in wet collections represent valuable material for scientific research. Here, we show that bat fly (Diptera, Nycteribiidae) samples contain DNA of Pseudogymnoascus destructans, a fungus pathogenic to bats. Using dual-probe quantitative PCR, we detected P. destructans DNA on bat flies collected in the Samara, Sverdlovsk and Irkuts...

A revision of the literature an...

Bats are hosts to a number of ectoparasites—acarines (ticks, chiggers, other mites), bat flies, and fleas. Bat ectoparasites might have significant ecological and public health importance as they may be potential vectors of zoonotic agents. It is important to identify their distribution, diversity, and host-parasite associations. Bat ectoparasites...
