Full textAbstract:
A serologic survey was carried out to detect the prevalence of Ehrlichia canis antibodies among privately-owned dogs in the counties of Varna, Silistra, Ruse, Montana, Veliko Tarnovo and Pleven of northern Bulgaria. A total of 120 serum samples were IFA tested for anti-Ehrlichia canis IgG antibodies. A mean seroprevalence rate of 37.5% was recorded with Varna county showing the highest value (60%) followed by Silistra (55%), Ruse (30%), Montana (30%), Veliko Tarnovo (25%) and Pleven (25%) counties. These results clearly show that dogs residing in northern Bulgaria are highly exposed to E. canis.

In Bulgaria, the first laboratory-confirmed West Nile neuroinvasive disease (WNND) case occurred in 2015 and more cases have been reported ever since. The aim of our study was to track the current circulation of West Nile virus (WNV) in the country. We collected 1830 serum samples from healthy people of every district in Bulgaria. Commercially available ELISA kits were used to detect specific anti-WNV IgG antibodies. All positive samples were tested for specific IgM antibodies using the same method. Possible risk factors were identified by calculating odds ratio. Specific IgG antibodies were detected in 22 of the samples (1.2%, CI 0.8% to 1.8%). No IgM antibodies were detected in the positive samples. The highest seroprevalence rates were found in the districts of Pleven, Varna, Silistra and Yambol. This study showed the continuous circulation and spread of WNV in Bulgaria

Bulgarian Journal of Soil Science, Agrochemistry and Ecology 57, no. 3 (September 25, 2023): 3–8. http://dx.doi.org/10.61308/bxla3227.
Full textAbstract:
On sites with weakly leached chernozems located in the agro-ecological conditions of the municipality of Kaynardzha, Silistra region, the soil fertility and the productivity of agricultural lands were assessed in two ways: 1. Through the routinely used in Bulgaria “Methodology for work on the cadaster of agricultural lands in NRB” (Petrov et al., 1988.) and 2. Through a newly developed methodology “Modern approaches for potential assessment (Land evaluation and categorization) of agricultural lands in Bulgaria” (Radovanova, 2020). The results showed the following: In the current evaluation, the average agronomic score of the lands subject to research under non-irrigated conditions is 69, and under irrigated conditions 86, i.e. this classifies land use suitability in the 4th and 2nd categories respectively. The obtained average agronomic scores at the potential assessment of 72 and 90 under non-irrigated and irrigated conditions, respectively, classify the suitability of these lands into the 3rd category (non-irrigated) and the 1st category (irrigated). The critical comparison of the results leads to the conclusion that even for lands with some of the most fertile Bulgarian soils, the current assessment does not reveal their full production potential. For practice, both assessments should be performed simultaneously. This would most accurately orient manufacturers for the type of technological solutions and the size of the necessary investments.

SUMMARY Sexual abuse is considered as a crime against the person all over the world. Despite the age of victims, it could trigger serious physical and psychological consequences, psychoactive substances and drug abuse, reproductive disorders, suicides and even death. The aim of retrospective investigation was to analyze the incidence of sexual assault in the regions of Varna (V), Silistra (S) and Gabrovo (G) in the period 1998-2006. The material used in the study involved the archive records of the Forensic Medicine Wards in the three studied regions. The comparative study employed inquiries and the documental interpretation method. The data of the investigations are filled in questionnaires in Microsoft Excel and compared. In conclusion, we could state that: 1. The female age group, most affected by sexual assault, was that of 14-17 years. 2. Most commonly, the sexual crimes are performed by persons familiar to the victims (50.10%). 3. Among men, the most affected age group was that under 14 years of age.

PROBLEMS of Infectious and Parasitic Diseases 49, no. 2 (August 27, 2021): 35–39. http://dx.doi.org/10.58395/pipd.v49i2.65.
Full textAbstract:
Background: Ixodid ticks are widely studied due to their epidemiological and epizootic importance. It is of great value to know vertebrate host preferences of ticks in order to understand their ecological relationships and distribution. Earlier studies report birds as important hosts of Ixodid tick and a total of 136 ticks species have been frequently found in birds worldwide. However, only few studies related to host preferences of ticks among wild birds in Bulgaria were conducted till now. Aim: To obtain new data on the host preferences of ixodid ticks among wild birds at three locations in Bulgaria. Material and methods: The study was conducted between 2010 – 2020 in three sites in Bulgaria – Biological Experimental Station Kalimok (Silistra region), near Brodilovo village (Burgas region), and the city of Sofia (city park). The birds were caught by mist nets and inspected for ticks. Ticks found were removed by fine tweezers or a special removal tool for ectoparasites. Tick identification was based on external morphological characteristics. Results: A total of 2419 individual birds belonging to 78 species were examined. Of these, 70 individuals (16 species) carried ticks, thus representing 2.9% infestation rate. A total of 262 ticks were collected and identified as: Ixodes ricinus, Hyalomma marginatum, Haemaphysalis punctata, Hae. concinna, Hae. sulcata and two specimens could only be identified to the genus Haemaphysalis. Ixodes ricinus was the most commonly encountered tick (224/262), predominantly nymphs, followed by Hyalomma marginatum (27/262). The highest prevalence of tick infestation was observed among the Eurasian Blackbird, Turdus merula (28.6%), followed by the common nightingale, Luscinia megarhynchos (12.9%) and the common chaffinch, Fringilla coelebs (11.3%). These three bird species harboured the majority of ticks on their heads – some single individuals were infested by 10 up to 25 ticks per bird. Conclusion: Ixodes ricinus was found as the predominant tick species in this study. Nymphs were the most frequently observed stage. Infesting both birds and humans, this tick species has the potential to spread local tick-borne infections.

Целью публикации является перевод на русский язык и всесторонний анализ «Страстей Юлия Ветерана» (BHL 4555). Описываемые события произошли в конце мая 303 г. в Дуросторуме в Нижней Мезии (совр. Силистра в Болгарии). Особое внимание при рассмотрении данных этого краткого, но очень интересного текста уделено таким вопросам, как исторический контекст мученичества, история раннего христианства на Балканах по данным литературной и археологической традиции, отношение христиан к воинской службе. Мы полагаем, что причиной смерти мученика стала проверка лояльности солдат XI Клавдиева легиона в связи со скорым прибытием туда Диоклетиана. The publication is a translation into Russian of «Passio of Julius the Veteran» (BHL 4555). Julius was executed on May 27, 303 in the Durostorum in Lower Moesia (now Silistra, Bulgaria). Commentary discusses some aspects of this text, related to the circumstances of the Julius’ martyrdom, the history of early Christianity in the Balkans, and the attitude of Christians to military service. We think that the cause of the martyr’s death was a test of the loyalty of the legion’s soldiers that was connected with the imminent visit of Diocletian (he was in the Durostorum on June 8, 303 - CJ 5.73.4).

Full textAbstract:
During the 19th century, significant changes occurred in the administrative and territorial structure of the Balkan provinces of the Ottoman Empire. The article analyzes the impact that these changes have had on the development of cities in the Bulgarian lands under Ottoman rule. The administrative rise of cities, such as Plovdiv, Bitola, and Ruschuk (Ruse), stimulated their economic and demographic development instead of other urban centres that were important in the past, such as Sofia, Nikopol, and Silistra. At the local level, the changes in the Ottoman administrative system have also had a significant impact, contributing to the upward development of settlements proclaimed as cities in the Stara Planina, Sredna Gora, and Sub-Balkan regions, such as Gabrovo, Koprivshtitsa, Panagyurishte, etc.

Full textAbstract:
The article is devoted to the fact that the Russo - Turkish war of 1828–1829 led to the mass resettlement of Bulgarians in Bessarabia, which was part of the Russian Empire since 1812. Transdanubian settlers received 50 dess. of land per family. The Bulgarians became colonists. Their legal status was enshrined in the "Charter of Foreign Colonies in the Empire." They were subordinated to the Trusteeship Committee for Foreign Immigrants of the Southern Territory of Russia and the Office for Transdanubian Immigrants. They had the opportunity to buy land outside the colonies, to engage in handicrafts and trade. The Bulgarians were released from military service. At the same time, the tsarist government paid little attention to the education of Transdanubian settlers, without allocating funds from the state budget. The education of the children of the Bessarabian Bulgarians was entrusted directly to the colonial societies. The Crimean War of 1853–1856 changed the position of the Bulgarians. Many of them voluntarily joined the Russian army to fight against foreign invaders. The Bulgarians defended Sevastopol, took part in the siege of the Turkish fortress of Silistria, and carried out a border guard in the ranks of the Danube Cossack army. Transdanubian settlers donated food and raised money for military needs. Russia's defeat in the Crimean War had a negative effect on their future because according to Article XXI of the Paris Peace Treaty, the three southern counties of Bessarabia came under the jurisdiction of the Principality of Moldavia. Outside Russia, there were 40 colonies with a population of 22,365 people. Thanks to the efforts of the Russian authorities, from 1857 to 1860 only 500 families of Bulgarian colonists returned to the land of their second homeland. Transdanubian migrants who remained within Russia found themselves in a difficult economic situation due to the severance of economic ties associated with the new border division. In addition, they had to provide apartments to Cossack troops and border guards. Despite all the difficulties, the Bulgarians remained colonists. The Russian government retained this status, hoping to attract new Slavic settlers from the Balkan possessions of the Ottoman Empire.

Full textAbstract:
Nowadays, in a world with rapidly growing population, the utilization of the available natural resources in a best possible way is obviously of highest priority. Significant part of the natural resources for a given region is the local biodiversity. Being in a climatically favorable environment, the cross-border area Romania - Bulgaria has a rich variety of plants with high potential not only in pharmacology and cosmetics but in many other fields. That is why, the project â€MedPlaNet - medicinal plant network for enhancement of the comparative advantage of Calarasi - Silistra cross-border area for sustainable development†developed an Oracle data base (http://medplanet.dbioro.eu) which includes a phyto-chemical screening of spontaneous and cultivated medicinal plants in the region, physical and chemical characteristics of the soils, technologies used for cultivation, harvesting and processing these herbs but also statistic studies about the use of medicinal and aromatic plants by the local population in both countries. The biologically active compounds identified in the medicinal plants are used in new formula of natural products as generators of new technologies for production and services, offering a chance for developing sound economy based on knowledge with high added value.

Full textAbstract:
Varna is located on a coastal plain situated on a bay having the same name in the Northeastern part of Bulgaria. Founded as a Greek colony in the 6th century BC, Varna was incorporated into the Danubian Bulgarian State (First Bulgarian State) in the late 8th century and converted to Christianity during the second half of the 9th century. Varna fell under Byzantine rule in 971 and this lasted for a long time. As from 13th century, Turkic people migrating to Anatolia were settled in Varna located within the borders of the Bulgarian State. Some of them returned to Anatolia and some others stayed in Dobruja and adopted Christianity. The descendants of these Christian Turks, called the Gagauz, founded an independent beylik in Dobruja. The capital city of this beylik was Kaliakra (Keligra) and was later moved to Varna. Varna and its surrounding region fell under Ottoman rule during the reign of Sultan Murad I. The Crusade of Varna 1444 between the Ottoman Empire and the Crusaders took place around the vicinity of Varna. After 1444, the Yoruk groups were settled in the villages destroyed by their abandoned populations. Administratively, Varna was subjected to the sanjak of Silistra from the 16th century. The data in the cadastral record books (tahrir defteri) indicate that the population of Varna increased throughout the 16th century. Under Ottoman rule, Varna was one of the commercially important centers on the route leading to Istanbul from the North of the Black Sea. Offering chances in terms of economic and commercial activities, Varna attracted both Muslims and non-Muslims. Varna was raided many times by the Prince of Wallachia Michael in the late 16th century, and by the Cossacks in the 17th century. The archive records show that the population of the district of Varna was reconstructed following these raids. New districts (Hacıoğlu Pazardzhik and Balchik) were founded around Varna in the second half of the 16th century. In the 17th century, the number of the villages and the population of Varna decreased due to not only the Cossack attacks but also these newly founded districts. This paper provides information regarding Varna coming under the Ottoman domination, its administrative organization, its settlement, and demographics. This information will contribute to the history of the district Varna’s administration, socio-economics, settlement, and demographics.

"CLUSTER ANALYSIS OF DISTRICTS IN BULGARIA ACCORDING TO THE DEVELOPMENT OF THE AGRARIAN SECTOR." IDARA 2023, no. 2 (February 15, 2024). http://dx.doi.org/10.37075/idara.2023.11.
Full textAbstract:
The purpose of the study is to classify the districts in Bulgaria according to some indicators characterizing the development of the agrarian sector. A cluster analysis (K-means clustering) was performed using the statistical software R and the packages „factoextra“ and „cluster“. The official statistical information of the NSI for 2021 was used for the following indicators: gross value added from Agriculture, Forestry and Fishery (GVA); employees under labour contract in Agriculture, Forestry and Fishery; average annual wages and salaries of the employees under labour contract in Agriculture, Forestry and Fishery. It was established that according to the development of the agrarian sector in 2021, the districts in Bulgaria can be classified into 4 clusters. The central point of the cluster with the most favorable values of the indicators in terms of agriculture has the following characteristics: GVA from agriculture – BGN 299 million; persons employed in agriculture – 3644 persons; average gross salary – BGN 15506. This cluster includes the districts Veliko Tarnovo, Ruse, Varna and Dobrich. The central point of the cluster, which ranks second in terms of realized development in the sector in 2021, can be described as follows: GVA – 278 million BGN; persons employed in the agricultural sector – 3857 persons; average annual gross salary – BGN 12032. The cluster unites the following districts: Pleven, Burgas, Stara Zagora, Pazardzhik and Plovdiv. The centroid of the cluster, ranked third in terms of development of the agrarian sector, is characterized by the following values of the considered indicators: GVA from agriculture – BGN 184 million; employed persons in the sector – 1789 persons; average annual salary – BGN 14206. This cluster includes the districts: Montana, Gabrovo, Razgrad, Targovishte, Shumen, Yambol, Sofia – grad and Smolyan. The central point of the cluster, ranked last in terms of realized development in the agrarian sector, has the following characteristics: GVA – BGN 183 million; employed persons – 1595 persons; average gross salary (annual) – BGN 11795. It includes the districts: Vidin, Vratsa, Lovech, Silistra, Sliven, Blagoevgrad, Kyustendil, Pernik, Sofia, Kardzhali and Haskovo. This is the cluster with the most unfavorable development of the agrarian sector during the considered period. Clusters unite districts, some of which are significantly distant from the central point of the cluster to which they belong. The explained variation in the clusters is 73,6%, which is relatively acceptable, but at the same time it also shows that 26,4% of the variation cannot be explained by the presented distribution of the districts by clusters. This also explains the relatively large distance between some districts and the corresponding centroid: these districts show significant differences from the central point, i.e. their classification cannot be considered successful. Such districts are Pernik, Plovdiv, Dobrich, Gabrovo, Smolyan and Shumen. In general, the first and third clusters appear to be the most homogeneous, and the second and fourth are the most heterogeneous. Keywords: cluster analysis, districts, agriculture
