Forecasting of Brucellosis Morbidity Rates in the Russian Federation Using Wald Method

Objective of the study is to conduct epidemiological analysis of official statistical data on brucellosis morbidity rates over the period of 2005–2014 in different constituent entities of the Russian Federation, using Wald method. Materials and methods. Utilized were recording and reporting documents of the Federal Service for Surveillance in the Sphere of Consumers Rights Protection and Human Welfare, FBHI “Federal Center of Hygiene and Epidemiology” of the Rospotrebnadzor, and WHO information resources.Results and conclusions. Studies of peculiarities of epidemic process development over the long-term period have allowed for identification of entities that are the most affected by the diseases. The results obtained on the morbidity rates in the Russian Federation over the period of 2005–2014 testify to the fact that first comes North Caucasian Federal District (NCFD) (62 %), next go Siberian (SbFD) (16 %) and Southern (SFD) (13 %) Federal Districts, second and third lines of the list respectively. Other regions account for 9 % of the load. The largest share of morbidity in NCFD entities belongs to the Republic of Dagestan – 62 %. Thereat, annual increment rate is 5.54 cases, which points to stabilization and some downward trend. Application of this morbidity rate prediction tool provides for in-time planning of clinical-diagnostic, prophylactic, and anti-epidemic measures in brucellosis foci. Wald method for forecasting of morbidity can be used for other infectious diseases too

Эпидемиология гепатита А и тактика вакцинопрофилактики

Hepatitis A (HA) is an acute infectious disease of the liver caused by the hepatitis A virus (HAV). HA disease incidence rate is closely linked to the social and economical development. The results of seroepidemiologic studies show that the prevalence of anti-HAV antibodies in population ranges from 15 to almost 100% in various countries of the world. The only reliable way to prevent hepatitis A virus (HAV) for today is the specific prophylactic vaccination. Recently developed inactivated vaccines against HAV have been successfully used in many countries. Vaccines authorized in Russia are safe, possess low reactogenicity and high immunogenicity. Practical experience in using vaccines during the outbreaks of HAV has shown that they possess epidemiological efficacy and provide necessary protection of the population in extreme conditions. This is clearly confirmed by single administration of vaccines to patients in epidemic focus of HAV. Constant regular monitoring of the duration of protection induced by one and two doses of the vaccine is required. The article considers WHO’s position on the use of vaccines for the prevention of HA. It describes the prospects of the further use of vaccines to control the spread of HA.Гепатит А (ГА) является острым инфекционным заболеванием печени, вызванным вирусом гепатита А (ВГА). Заболеваемость ГА тесно связана с социально-экономическим развитием, серо-эпидемиологические исследования показывают, что распространенность анти-ВГА антител среди населения колеблется от 15 до почти 100% в разных странах мира. Единственно надежным средством предотвращения вирусного гепатита А (ВГА) в настоящее время является специфическая профилактика с использованием вакцин. Созданные в последние годы инактивированные вакцины против ВГА с успехом применяются во многих странах мира. Зарегистрированные в России вакцины безопасны, слабореактогенны и обладают высокой иммуногенностью. Опыт практического применения вакцин в очагах ВГА показал, что они обладают эпидемиологической эффективностью и обеспечивают необходимую защиту населения в экстремальных условиях. Наглядно это подтверждается при однократном введении вакцин лицам в эпидемических очагах ВГА. Необходим постоянный регулярный мониторинг продолжительности защиты, индуцированной одной и двумя дозами вакцины. Рассмотрена позиция ВОЗ в отношении применения вакцин для профилактики ГА. Представлены перспективы дальнейшего использования вакцин для контроля над распространением ГА

Animal models of major depressive disorder and the implications for drug discovery and development

Introduction: Depression is a highly debilitating psychiatric disorder that affects the global population and causes severe disabilities and suicide. Depression pathogenesis remains poorly understood, and the disorder is often treatment-resistant and recurrent, necessitating the development of novel therapies, models and concepts in this field. Areas covered: Animal models are indispensable for translational biological psychiatry, and markedly advance the study of depression. Novel approaches continuously emerge that may help untangle the disorder heterogeneity and unclear categories of disease classification systems. Some of these approaches include widening the spectrum of model species used for translational research, using a broader range of test paradigms, exploring new pathogenic pathways and biomarkers, and focusing more closely on processes beyond neural cells (e.g. glial, inflammatory and metabolic deficits). Expert opinion: Dividing the core symptoms into easily translatable, evolutionarily conserved phenotypes is an effective way to reevaluate current depression modeling. Conceptually novel approaches based on the endophenotype paradigm, cross-species trait genetics and ‘domain interplay concept’, as well as using a wider spectrum of model organisms and target systems will enhance experimental modeling of depression and antidepressant drug discovery. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group

Factors associated with diversity, quantity and zoonotic potential of ectoparasites on urban mice and voles

Wild rodents are important hosts for tick larvae but co-infestations with other mites and insects are largely neglected. Small rodents were trapped at four study sites in Berlin, Germany, to quantify their ectoparasite diversity. Host-specific, spatial and temporal occurrence of ectoparasites was determined to assess their influence on direct and indirect zoonotic risk due to mice and voles in an urban agglomeration. Rodent-associated arthropods were diverse, including 63 species observed on six host species with an overall prevalence of 99%. The tick Ixodes ricinus was the most prevalent species, found on 56% of the rodents. The trapping location clearly affected the presence of different rodent species and, therefore, the occurrence of particular host-specific parasites. In Berlin, fewer temporary and periodic parasite species as well as non-parasitic species (fleas, chiggers and nidicolous Gamasina) were detected than reported from rural areas. In addition, abundance of parasites with low host-specificity (ticks, fleas and chiggers) apparently decreased with increasing landscape fragmentation associated with a gradient of urbanisation. In contrast, stationary ectoparasites, closely adapted to the rodent host, such as the fur mites Myobiidae and Listrophoridae, were most abundant at the two urban sites. A direct zoonotic risk of infection for people may only be posed by Nosopsyllus fasciatus fleas, which were prevalent even in the city centre. More importantly, peridomestic rodents clearly supported the life cycle of ticks in the city as hosts for their subadult stages. In addition to trapping location, season, host species, body condition and host sex, infestation with fleas, gamasid Laelapidae mites and prostigmatic Myobiidae mites were associated with significantly altered abundance of I. ricinus larvae on mice and voles. Whether this is caused by predation, grooming behaviour or interaction with the host immune system is unclear. The present study constitutes a basis to identify interactions and vector function of rodent-associated arthropods and their potential impact on zoonotic diseases

Cross-species Analyses of Intra-species Behavioral Differences in Mammals and Fish

Multiple species display robust behavioral variance among individuals due to different genetic, genomic, epigenetic, neuroplasticity and environmental factors. Behavioral individuality has been extensively studied in various animal models, including rodents and other mammals. Fish, such as zebrafish (Danio rerio), have recently emerged as powerful aquatic model organisms with overt individual differences in behavioral, nociceptive and other CNS traits. Here, we evaluate individual behavioral differences in mammals and fish, emphasizing the importance of cross-species analyses of intraspecies variance in experimental models of normal and pathological CNS functions. © 2019 IBROAVK laboratory is supported by the Southwest University (Chongqing, China) Zebrafish Platform construction funds.
