Hepatitis E virus (HEV) is an emerging zoonotic pathogen with different viral genera and species reported in a wide range of animals. Rodents, particularly rats, carry the specific genus rat HEV (Rocahepevirus genus, genotype C1) and are exposed occasionally to HEV-3 (Paslahepevirus genus, genotype 3), a zoonotic genotype identified in humans and w...
The impact of mosquito-borne diseases on human and veterinary health is being exacerbated by rapid environmental changes caused mainly by changing climatic patterns and globalization. To gain insight into mosquito-borne virus circulation from two counties in eastern and southeastern Romania, we have used a combination of sampling methods in natural...
bstract: Biodiversity assessment is crucial for evaluating the ecological status of freshwater ecosystems. Macroinvertebrates are one of the ecological indicators used for water quality assessment. In many cases, morphological identification of macroinvertebrates poses problems when different life stages need to be identified to the species level....
Culex pipiens pipiens and Culex pipiens molestus mosquitoes are the vectors of West Nile virus in south-eastern Romania, an area of intense circulation and human transmission of this virus. The level of insecticide resistance for the mosquito populations in the region has not been previously assessed. Culex pipiens mosquitoes collected between 2018...
1. Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for de...

The purpose of this research was to improve the epidemiological data on HEV infection in the human population in Romania. The analysis targeted hospitalized subjects with acute hepatitis (n = 94) of unknown etiology from the Infectious Diseases Regional Hospital in Iasi. Moreover, patients without liver disease (n = 40) from a different county hosp...
The present study aimed at identifying Mycobacterium avium seroprevalence in wild boars (Sus scrofa) and red foxes (Vulpes vulpes) samples, from the Eastern region of Romania, by using an indirect ELISA assay. A total of 367 wild animal samples were collected from eight counties: 275 wild boars sera samples from Iasi (n=209), Botosani (n=11), Bacau...
Waterfowls are considered to be the main natural source of avian influenza. The virus spreads at local, regional, continental and intercontinental levels via bird migration. There is a lot of information regarding infections in waterfowls and domestic birds, but little regarding other birds. Still, there is evidence of sensitivity and the importanc...
Hepatitis E virus (HEV) has significantly impacted humans due to its potential to cause acute viral hepatitis. Discovery of hepatitis E virus in domestic pigs and wild boars worldwide and the realization that it is highly prevalent, raised concerns of the implications for food-borne transmission of HEV in Europe. Present work focusses on molecular...

West Nile virus (WNV) infection causes diseases that vary in intensity from asymptomatic to fatal encephalitis in humans and animals. The etiological agent is a Flavivirus belonging to Japanesse Encephalitis complex. This zoonotic virus is maintained in nature in an enzootic cycle between mosquitoes and birds as amplifying hosts. Except birds, a wi...
Ixodid ticks are competent vectors for multiple pathogens, several of which cause infections in human. The medical importance of tick-borne pathogens is well known, yet unanswered questions remain regarding the occurrence of pathogens such as Rickettsia spp., Anaplasma phagocytophilum, and "Candidatus Neoehrlichia mikurensis" in questing ticks in R...
A serosurvey for Tahyna virus (TAHV), a mosquito-borne California encephalitis orthobunyavirus (Peribunyaviridae) endemic to Europe, was performed to estimate the activity of TAHV on a broad geographic scale. Sera from wild boar (Sus scrofa), roe deer (Capreolus capreolus) and red deer (Cervus elaphus) were collected from Austria, Hungary and Roman...
In industrialized countries, Hepatitis E is a recognized zoonosis, with wild boar and swine representing the main reservoirs for zoonotic genotype HEV-3 in Europe. Data related to HEV infection in wild boar population in Romania are restricted to serological surveys. Therefore, our main goal was to determine the HEV prevalence in wild boar populati...
Identifying Borrelia burgdorferi as the causative agent of Lyme disease in 1981 was a watershed moment in understanding the major impact that tick-borne zoonoses can have on public health worldwide, particularly in Europe and the USA. The medical importance of tick-borne diseases has long since been acknowledged, yet little is known regarding the o...
West Nile Virus (WNV) is the etiological agent of the WN fever/encephalitis, a re-emerging zoonosis signalled frequently in the last decades in the whole world. The virus can cause severe neurological disease in horses and humans but in many other species specific WNV seroconversion is signalled and may be an useful epidemiological tool. Wild anima...
