“…в последние два десятилетия в российской Федерации бруцеллез остается достаточно широко распространенной инфекцией в регионах с интенсивным разведением скота, особенно на юге европейской части, и одной из частых причин значительного экономического ущерба в животноводстве. отмечается нестабильная эпидемиологическая обстановка при стойкой энзоотичности по бруцеллезу среди крупного и мелкого рогатого скота [3].…”

“…особое внимание необходимо уделить животным и продукции животноводства, ввозимым в россию из неблагополучных по бруцеллезу стран ближнего востока (сирия, палестина, иран, турция, саудовская аравия), где численность поголовья овец и коз составляет более 85 % от общего количества мелких жвачных в мире, при этом плотность мрс почти в два раза выше мировых значений [2,3]. потенциально высокие эпидемиологические риски для россии могут нести животноводческая продукция (сырье) и живой скот из государств восточной европы и центральной азии (в первую очередь страны, с которыми исторически сложились тесные социально-экономические отношения: киргизия, казахстан, туркменистан, таджикистан, армения, грузия, монголия, азербайджан и узбекистан).…”

An analysis of brucellosis incidence in Russia in 2013–2022 and the data on genetic diversity of Brucella melitensis and Brucella abortus populations isolated in Russia in 1939–2022 are provided in the review. Over the past decade, the epidemiological situation in Russia has been characterized as unstable against the background of persistent unfavorable conditions for brucellosis in cattle and small ruminants. During the period of 2013–2022 (9 months), 4298 epizootic foci as regards brucellosis in cattle (89164 sick animals) and 371 as regards brucellosis in small ruminants (13569) were registered. The largest number of epizootic brucellosis foci was recorded in the North-Caucasian and Southern Federal Districts. In 2013–2022, on average, 327 cases of brucellosis among people were registered annually, the incidence rate per 100 000 of the population was 0.24. Up to 70–90 % of brucellosis cases were detected in the south of the European part of the country. A trend towards deterioration of the situation on brucellosis in Volga (Penza and Samara Regions) and Central (Smolensk, Voronezh and Tula Regions) Federal Districts is observed. There is a connection between the intensity of epidemic manifestations of brucellosis and the level of anthropurgic enzooty of territories. In 2022, 467 cases of brucellosis were reported (0.32 per 100 000 of the population), which is 42.8 % higher than annual average values over 10 years. In 2023, a measure of stability of incidence rates, by 20–25 % above average long-term values, is to be expected. Incidence of brucellosis in humans will be within the range of 380–410 cases (0.26–0.28 per 100 000 of the population). The results of genotyping of B. melitensis strains point to an increase in the proportion of isolates with an MLVA-profile characteristic of strains from enzootic as regards brucellosis countries of Middle East and North Africa over past 20–25 years, which can indicate importation (introduction) of the infection from these territories to Russia through small ruminants and/or biomaterial from them.

Brucellosis is one of the most common zoonotic diseases in the world. The epidemiological situation of brucellosis in the Russian Federation is characterized as unfavorable. The problem of brucellosis remains of particular relevance in regions with developed animal husbandry. Many different clinical manifestations and the absence of specific symptoms of brucellosis make it difficult to diagnose this disease. The clinical case presented in this paper illustrates the delayed diagnosis of brucellosis in a 10-year-old patient with fever, enlarged lymph nodes, liver and spleen. The defects in the provision of medical care were based on the lack of alertness of doctors regarding brucellosis, insufficient interpretation of epidemiological history data and incorrect assessment of the totality of clinical syndromes of the disease and laboratory parameters. As a result, brucellosis was diagnosed only six months after the onset of the disease. Subsequent etiotropic therapy led to stabilization of the patient's condition, who was discharged from the hospital with recommendations under the supervision of an infectious disease specialist.

The aim of the present study was to evaluate the effectiveness of analysis of the high resolution melting curves obtained after amplification of VNTR loci for the identification and differentiation of Brucella strains.Materials and methods. 16 strains of Brucella species – B. canis (n=1), B. abortus (n=9), B. melitensis (n=2), B. suis (n=4) – of different geographical origin were used as objects of the research. The MLVA-typing was performed using conventional PCR followed by separation of amplicons in agarose gel and real-time PCR with post-amplification analysis of the curves of VNTR loci melting in the presence of intercalating dye SybrGreen. Bioinformatics analysis was conducted with the help of Vector NTI 9.1, Mega 11 software (MUSCLE algorithm). Phylogenetic analysis was carried out applying UPGMA method using the Mega 11 program.Results and discussion. MLVA approach based on the analysis of the melting point curves of the obtained after amplification of VNTR-loci PCR fragments has shown that each of the 16 strains of Brucella is characterized by a unique melting temperature profile. PCR followed by electrophoresis has demonstrated that despite the high variability of the used VNTR sequences (h=0.48…0.74), only post-amplification melting curves of the Bru7, Bru9, Bru18, Bru21 loci had sufficient information content to determine the genetic polymorphism of the studied Brucella strains. Based on the results of phylogenetic analysis of the Bru7, Bru9, Bru18, Bru21 sequences, it has been found that the majority of the studied Brucella strains are distributed in the dendrogram in accordance with their taxonomic and geographical position. Thus, HRM analysis of melting curves obtained after amplification of the Bru7, Bru9, Bru18, Bru21 loci has the potential to be used for differentiating Brucella strains.
