DETECTION OF HERPESVIRUSES IN PASSERINE BIRDS CAPTURED DURING AUTUMN MIGRATION IN SLOVENIA.

Herpesviruses (HVs) were detected by PCR in the cloacal swabs of 0.76% (4/525) clinically healthy free-living passerine birds from 32 different species captured in mist nets in Slovenia during the 2014 and 2017 autumn migrations. Herpesviruses were detected in the Eurasian Blackcap (Sylvia atricapilla), the Common Blackbird (Turdus merula), and the Eurasian Blue Tit (Cyanistes caeruleus).

Entomological Surveillance and Cantharidin Concentrations in and Blister Beetles in Slovenia.

True blister beetles (genus , family Meloidae) produce cantharidin, which can cause toxicosis in humans and animals. Some recent reports suggest that poisoning by the blister beetle has occurred in the Mediterranean part of Slovenia, which has never been reported before. Drought and modern harvesting techniques are thought to increase the likelihood of blister beetle forage contamination and cantharidin intoxication in animals.

Checklist and provisional atlas of singing cicadas (Hemiptera: Cicadidae) of Bulgaria, based on bioacoustics.

Background: The singing cicadas (Hemiptera: Cicadidae) of Bulgaria were poorly known. There are published records for 14 species: , , , , , , , , , , , , and .

New Information: Two species from this list were doubtful in the beginning of our study, since is distributed in central and southern Portugal and is a north African species.

Host dispersal shapes the population structure of a tick-borne bacterial pathogen.

Birds are hosts for several zoonotic pathogens. Because of their high mobility, especially of longdistance migrants, birds can disperse these pathogens, affecting their distribution and phylogeography. We focused on Borrelia burgdorferi sensu lato, which includes the causative agents of Lyme borreliosis, as an example for tick-borne pathogens, to address the role of birds as propagation hosts of zoonotic agents at a large geographical scale.

Complex within a Complex: Integrative Taxonomy Reveals Hidden Diversity in Cicadetta brevipennis (Hemiptera: Cicadidae) and Unexpected Relationships with a Song Divergent Relative.

Multiple sources of data in combination are essential for species delimitation and classification of difficult taxonomic groups. Here we investigate a cicada taxon with unusual cryptic diversity and we attempt to resolve seemingly contradictory data sets. Cicada songs act as species-specific premating barriers and have been used extensively to reveal hidden taxonomic diversity in morphologically similar species.

Prevalence and molecular characterization of Clostridium difficile isolated from European Barn Swallows (Hirundo rustica) during migration.

Background: Clostridium difficile is an important bacterial pathogen of humans and a variety of animal species. Birds, especially migratory passerine species, can play a role in the spread of many pathogens, including Clostridium difficile. Barn Swallows (Hirundo rustica) nest in close proximity to human habitats and their biology is closely associated with cattle farming.

Phylogeographic diversity of pathogenic and non-pathogenic hantaviruses in slovenia.

Slovenia is a very diverse country from a natural geography point of view, with many different habitats within a relatively small area, in addition to major geological and climatic differences. It is therefore not surprising that several small mammal species have been confirmed to harbour hantaviruses: A. flavicollis (Dobrava virus), A.

New distributional and bioacoustic data about Cicadivetta goumenissa from Peloponnese, Greece (Hemiptera, Cicadidae).

Cicadivetta goumenissa, a small singing cicada described recently by Gogala et al. (2012), has been previously found only around the village of Goumenissa in northern Peloponnese. We visited this area again in June 2012 and tried to determine the distribution range of this species.

Molecular evidence and high genetic diversity of shrew-borne Seewis virus in Slovenia.

Seewis virus, the shrew-borne hantavirus from Sorex araneus, has been molecularly detected in reservoir hosts in many different central European countries and Russia. Slovenia is a known endemic country for rodent-borne hantaviruses, therefore the aim of the study was to investigate the presence of shrew-borne hantaviruses in insectivores. Viral L, S and M segment have been recovered only from tissue samples of 7 S.

Patterns of tick-borne encephalitis virus infection in rodents in Slovenia.

Tick-borne encephalitis virus (TBEV) is the most important causative agent of arboviral infection in Europe, causing neurologic symptoms. The incidence of the disease has greatly increased over the past decades, and in the meantime, some changes in spatial distribution of TBE cases have been observed. Therefore, it is important to recognize the distribution of endemic areas, to use preventive measures successfully.

Zero prevalence of Clostridium difficile in wild passerine birds in Europe.

Clostridium difficile is an important bacterial pathogen of humans and a variety of animal species, where it can cause significant medical problems. The major public health concern is the possibility of inapparent animal reservoirs of C. difficile and shedding of bacteria to noninfected individuals or populations, as well as being a source of food contamination.

Prevalence and molecular characterization of tick-borne encephalitis virus in Ixodes ricinus ticks collected in Slovenia.

The hard tick Ixodes ricinus is the principal vector of tick-borne encephalitis virus (TBEV) in Slovenia; but until now, there was no information about the prevalence of TBEV infection in Slovenian ticks. We conducted a 2-year survey in 2005 and 2006, during which we were collecting I. ricinus ticks monthly in eight different locations of Slovenia.

Rickettsia hoogstraalii sp. nov., isolated from hard- and soft-bodied ticks.

A novel spotted fever group Rickettsia was found in Haemaphysalis sulcata ticks collected from sheep and goats in Croatia in 2006. At the same time, a genetically identical organism was co-isolated with the embryonic cell line CCE3 obtained from the soft tick Carios capensis in Georgia, USA. In this study, further phenotypic and genotypic characteristics of the novel rickettsial strain present in H.

First molecular evidence of Tula hantavirus in Microtus voles in Slovenia.

Different Microtus species, present in a worldwide range habitat populating North America, Europe, Asia, and few other species have been recognized previously as a hantavirus reservoir. Tula hantavirus was first reported in Microtus arvalis and Microtus rossiaemeridionalis from Central Russia and later discovered in several European countries. Using molecular techniques we have demonstrated the presence of Tula hantavirus in three different Microtus species in Slovenia.

The hantaviral load in tissues of naturally infected rodents.

Hantaviruses cause a lifelong and asymptomatic infection in naturally infected hosts as well as in experimentally infected rodents. Understanding the ecology and pathogenesis of hantaviruses requires an interdisciplinary research approach, which links laboratory experiments with results gained from field studies. Although several studies report hantavirus persistence and tissue infection patterns for experimentally infected rodents, field data is very limited.

Molecular detection of Theileria sp. in ticks and naturally infected sheep.

Seven healthy sheep and 10 sheep diagnosed with piroplasmosis based on clinical signs were tested for the presence of babesiae and theileriae. Using the molecular techniques, two species of theileriae were detected and characterized. Theileria ovis was present mostly in healthy sheep and in Rhipicephalus ticks collected from infected sheep.

Molecular detection of Bartonella species infecting rodents in Slovenia.

Rodents, collected in three zoogeographical regions across Slovenia, were tested for the presence of bartonellae using direct PCR-based amplification of 16S/23S rRNA gene intergenic spacer region (ITS) fragments from splenic DNA extracts. Bartonella DNA was detected in four species of rodents, Apodemus flavicollis, Apodemus sylvaticus, Apodemus agrarius and Clethrionomys glareolus, in all three zoogeographic regions at an overall prevalence of 40.4%.

Molecular identification of Rickettsia felis-like bacteria in Haemaphysalis sulcata ticks collected from domestic animals in southern Croatia.

Haemaphysalis sulcata ticks collected from sheep and goats in southern Croatia were found infected with rickettsiae. Molecular analysis of the complete gltA gene and portion of 17 kDa and ompB genes revealed the presence of Rickettsia felis-like bacteria in up to 26% of tested ticks.

Bioacoustic investigations and taxonomic considerations on the Cicadetta montana species complex (Homoptera: Cicadoidea: Tibicinidae).

Recent bioacoustic investigations have shown that Cicadetta montana Scopoli 1772 is a complex of morphologically similar sister species that are best characterized by their song patterns. At the type locality of C. montana, only mountain cicadas with simple, long lasting song phrases were heard, recorded and collected.

Detection and identification of spotted fever group rickettsiae in ticks collected in southern Croatia.

A total of 197 ticks belonging to four species (Haemaphysalis punctata, Hyalomma marginatum, Rhipicephalus bursa and Dermacentor marginatus) collected in October 2000 from domestic animals in southern Croatia were examined for the presence of rickettsiae by molecular techniques. Specific sequences of the rickettsiae were detected in 25 (12.7%) of ticks tested.
