Abstract:

Bluetongue virus (BTV) is the prototype species of the genus Orbivirus within the family Reoviridae. There are 24 (possibly 25) distinct serotypes of BTV, eleven of which have entered, or have been identified in Europe and the Mediterranean region since 1998 (types 1, 2, 4, 6, 8, 9, 11, 15, 16, 24 and 25). The first BTV to arrive in Greece during 1998 was serotype 9 (isolate GRE1998/01), followed by BTV-16 (GRE1999/13) during 1999. BTV-9 spread to mainland Greece, South-Eastern Bulgaria and European Turkey during 1999, to Italy during 2000, then to Serbia, Montenegro, Kosovo, Macedonia, Bulga

Abstract:

Bluetongue is a non-contagious, arthropod-borne viral disease of both domestic and wild ruminants. Bluetongue virus (BTV) is endemic in some areas where cattle and wild ruminants serve as reservoirs for the virus. Some authors suggest that a fundamental change in the European ecosystem since 1998, mostly linked to climate change, may have influenced the introduction and survival of BTV in Europe. Genetic analyses of bluetongue viruses isolated in Europe during this period showed that six virus types (1, 2, 4, 8, 9 and 16) have entered the region since that period.

Abstract The article reviews a current bluetongue (BT) epidemiological situation in Europe, BT restricted zones and the role of wild ungulates as a reservoir for bluetongue virus (BTV) and its transmission. BT has been eradicated from central and northern Europe, however it is still circulating in some regions of southern and south-eastern Europe. According to the recent information of the Directoriate General for Health and Consumer Affairs (DG SANCO) disease caused by BTV1 was spreading at the beginning of 2014 in Corsica (France). Moreover, four BTV1 cases were noticed in the west Spain (Cá

Abstract:

Bluetongue (BT) is an acute, viral, vector-borne, non-contagious disease of ruminants caused by Bluetonguevirus (BTV). Twenty-six different serotypes have been identified, and the ability of each strain to cause disease varies widely. BTV can infect a wide range of domestic and wild ruminants - sheep, goats, cattle, buffalo, deer, most species of African antelope and camels. For the study period (2011-2021), outbreaks were declared in 21 member states in Europe with predominant serotypes 1, 4 and 8. Based on data from Animal Disease Information System (ADIS) with the present paper we analyzed

Abstract:

Bluetongue (BT) is an acute, viral, vector-borne, non-contagious disease of ruminants caused by the Bluetongue virus (BTV). It is transmitted by insects of the genus Culicoides. It is characterized by some strong seasonal dynamics in the countries of temperate latitudes mid-latitude climates, associated with the period of active flight of vectors. With this study we set a goal to make a scientific assessment of the appropriate period for general vaccination against bluetongue in ruminants in the territory of the Republic of Bulgaria in 2021. Taking into account the life cycle of the vectors, t

This report examines the impact of the COVID-19 pandemic on the structure of the four main morning blocks in Bulgaria – “The Day Begins” on BNT, “Hello, Bulgaria” on Nova Television, “This Morning” on BTV and “Bulgaria Morning” on Bulgaria ON AIR. The purpose of the report is to track how the content and structure of the four morning television blocks changes due to the impact of the pandemic over a period of two years (from 2020 to 2023). When choosing the methodology for conducting the research, the nature of the set goal is taken into account, adhering to the principles of high ethics and e

The Infra-Getic Unit is a palaeogeographic unit, predestined by palaeotectonics. From the point of view of geological heritage, it represents a geosites framework. For the purpose of the correlation, the Serbian sections of Lukanja, Bogorodica Monastery, Rosomac and Senokos, as well as the Bulgarian sections of Komshtitsa, Gintsi, and Stanyantsi were used. The Jurassic sediments of the Infra-Getic Unit crop out on the southern slops of the Stara Planina Mountain in east Serbia and west Bulgaria. The Lower Jurassic started with continental and continental-marine sediments (clays and sandstones)

The article reviews the present epidemiological situation of bluetongue (BT) in Europe. After a four year break, disease caused by BTV serotype 8 reappeared in west Europe. On 11 September 2015, an outbreak of BTV8 was confirmed in central France (Allier department), and four weeks later, on 6 October, 45 outbreaks of 118 cases were confirmed in Allier, Puy-de-Dome, Creuse, Nicvre and Cher departments. Besides, BT caused by BTV1 and BTV4 is still circulating in some regions of southern and south-eastern Europe. Since 2013 disease caused by BTV1 was spreading extensively over the central and so

Abstract:

Studies on the molecular biological features of bovine herpesvirus 4 (BHV 4) strains isolated in Bulgaria have been conducted. Two types of polymerase chain reaction have been developed and applied to confirm the gB and TK genes. A restrictase fragment analysis was performed using various types of restrictase enzymes. The tested Bulgarian strains differed in their restrictase genomic profile from the reference European strain Movar 33/63 and from the American strain DN 599, and were clearly different each from the other. No clear relationship has been established between the restrictase enzyme

Abstract:

Cattle infected with BHV 4 show respiratory symptoms, gastrointestinal and postnatal genital disorders. The virus is a cofactor of bacterial infections. This paper reflects data on the prevalence of BHV 4 infections in several herds, among breeding animals and bulls from artificial insemination stations (AIS). One hundred and twenty six serum samples from bulls were investigated by MVNT and 45 (35.7%) were positive. Epizootiological and clinical studies on the prevalence of BHV 4 infections were limited to bovine farms with suspected infection with this virus. To establish seroconversion to th

Abstract:

The paper reports on the cleaning of the Hurtlex lexicon for Bulgarian as part of the multilingual Hurtlex resource. All the challenges during the cleaning process are presented, such as: deleting strings or lexica that are clear errors from the automatic translation, establishing criteria for keeping or discarding a lexeme based on its meaning and potential usages, contextualizing the lexeme with the meaning through an example, etc. In addition, the paper discusses the mapping of the offensive lexica to the BTB-Wordnet as well as the system that has been used.

We present Fabry-Pérot interferometric observations of the northeastern shock filaments in the Cygnus Loop supernova remnant. These observations were obtained using the SCORPIO-2 spectrograph (Spectral Camera with Optical Reducer for Photometrical and Interferometrical Observations - 2) at the 6m Big Telescope Azimuthal (BTA). We will show preliminary results on Hα-line parameters measured in shock filaments across a 6.3' x 6.3' field of view, with an angular resolution of 3" and a high spectral resolution of 23 km/s (FWHM).

The paper reports on the current status of a system for creating dictionaries within the CLaDA-BG infrastructure. The system is called CLaDA-BG-Dict. At the heart of the system lies the lexical thesaurus BTB-Wordnet around which all other language resources for Bulgarian are organized. These are various types of dictionaries (morphological, explanatory, terminological, etc.), ontologies (such as DBpedia), corpora (in-house and external). The specific features and functionalities of the system are discussed with respect to the language resourse integrity. Also, the rationale behind the construc
