Russia has a number of historical foci of zoonotic anthropogenic diseases. In Central Russia, the Republic of Mordovia is one of such areas, a region being known to have foci of haemorrhagic fever with renal syndrome (HFRS) and tularemia. It therefore requires continuous monitoring. The role of small terrestrial mammals as reservoirs of zoonoses has been previously proven for the region. The aim of this work is to take an integrated approach to assess the role of terrestrial and subterranean small mammals. Subterranean mammals are often not considered important reservoirs of zoonotic pathogens that cause human morbidity. Among small mammals in the wild environment, the bank vole, the yellow-necked mouse and the house mouse play important roles as vectors of zoonoses. Among wild subterranean mammals, the greater mole rat is important as a vector of tularemia and HFRS.We analyzed homogenized internal organs of these animals (lungs, spleen, kidneys). Of all samples from the greater mole rat, 83% were positive for tularemia antigens and 17% were positive for HFRS. None of the analyzed European moles had antigens of tularemia and HFRS. No double infection with both tularemia and hantavirus was detected in the subterranean mammals. Double infection was found among terrestrial mammals in the bank vole and the forest dormouse.

Small mammals are important reservoirs for zoonotic pathogens that cause significant morbidity in humans. Of these, tularemia and hemorrhagic fever with renal syndrome (HFRS) are among of the most widespread zoonotic diseases worldwide. Despite the fact that both pathogens have great epidemiological significance in Russia, epizootological data for urbanized areas are still scarce. This study was conducted to investigate the occurrence and prevalence of tularemia and hantaviruses in small mammals living in close proximity to humans. Altogether, 425 small mammals (278 from urban environment and 147 from natural environment) representing nine species (Myodes glareolus, Microtus arvalis, Cricetus cricetus, Apodemus flavicollis, Apodemus agrarius, Apodemus uralensis, Mus musculus, Sorex araneus and Neomys fodiens) were captured in the Russian Republic of Mordovia and screened for pathogens using different serological and bacteriological methods. Red bank vole (M. glareolus) and yellow-necked wood mouse (A. flavicollis) are among species in the forest zone of the city of Saransk and are the source of a number of zoonotic diseases. In the non-urban environment, the main role as carriers of zoonotic diseases was played by house (M. musculus) and striped field (A. agrarius) mice. A total of 23 % of the small mammals sampled in Saransk were positive for tularemia, whereas 9.7 % were positive for HFRS. Furthermore, dual infections with both tularemia and hantaviruses were shown in 1.4 % of animals, suggesting that the same small mammal host can be infected with several pathogens at the same time, therefore representing a serious threat to public health. Small mammal ecology is a primary determinant of zoonotic pathogens dynamics in rodent populations and the risk of pathogen transmission to people.

Objective; analysis of the dynamics of the main indicators of the ТВ epidemic in the Saratov region during the 5-year period. Material and Methods. The analysis of major indicators of epidemic (morbidity and mortality) in the Saratov region during the five years of observation. In the work a comparative evaluation of the parameters studied with analogical indicators in the Russian Federation was carried out. Results. During the period from 2009 to 2013 situation of tuberculosis epidemic in the Saratov region has positively stabilized. Over the past five years, the mortality rate in the region has decreased, while in the Russian Federation as a whole only on 25%, the incidence of the population in the region fell by 20%. It has been established that the later detection of a tuberculosis process leads to an increase in mortality and maintains reservoir of ТВ infection. Conclusion. In the Saratov region ТВ infection is thoroughly controlled. There is a well-established system for the detection, diagnosis, treatment and prevention of this specific process.

The article presents an overview of the domestic medical literature, reflecting the incidence of syphilis in the Russian army and the Russian military civilians in times of conflict in the XVII — beginning of XX century. The methods of struggle with sexually transmitted diseases and their prevention in the military in wartime and peacetime are present.

The aim of the study was to analyze epidemiological and demographic characteristics of patients with myasthenia gravis in the Samara region. Material and methods. Data of electronic register of Regional myasthenic center containing information about 340 patients were used. Prevalence of myasthenia gravis in area made up 9,7; average annual disease over the last 10 years — 0,73 per 100000. Results. The data obtained are comparable with the global characteristics of the disease, but higher than the figures of some domestic researches. Conclusion. Confirms the fact that in regions where work specialized myasthenic centers, epidemiological parameters are always higher.

The research goal is to evaluate the epidemiology of syphilis and neurosyphilis in the Saratov region science 1994 till 2010. Materials and methods: The forms of statistical inquiry in the Saratov region have been studied. The results of syphilis blood tests were examined in neurological departments of Saratov hospitals. Results: The tendency to reduction of syphilis morbidity was revealed in the Saratov region while the incidence of neurosyphilis increased. Severe forms of symptomatic neurosyphilis were predominant. In spite of increasing number of positive syphilis serological tests in neurological hospitals of Saratov the detection of neurosyphilis among neurological patients remained low. Conclusion: Neurosyphilis has become a common disease in the Saratov region. The issues of diagnostics and treatment of neurosyphilis should be considered by close cooperation between dermatologists and neurologists

The research work has been carried out on the basis of official statistics data and results of curator departures. The purpose is to study the basic tendencies of tuberculosis epidemic situation among children for the period from 2004 till 2008 in the region of the North-west of Russia for working out priority antitubercular scheme. The disease morbidity has been investigated. Tendencies of situation development in each region with application of an estimation of morbidity rate have been defined. The nonparametric factor of correlation of Spirmen (c) has been taken into account. It is established that in case of normal epidemic situation, the basic indicators of tuberculosis in children from the Northwest of Russia are higher than all over the country. Epidemic situation in Kaliningrad is marked by accumulation of MBT+ in contingents. St.-Petersburg and Kaliningrad epidemic statistics accounts 52% from total number of ill children that influences a district indicator. In Kaliningrad and Arkhangelsk regions children from contact as a result of accumulation of adult MBT+ in contingents fall ill more often. The main method to reveal the pathology among children in St.-Petersburg is prevention, however children morbidity from contact with MBT+ in 2008 in 1,8 times lower than in the North-west Russia. The received data have found out that in Kaliningrad and Arkhangelsk regions the main direction in the antitubercular scheme is an increase in efficiency of treatment of tuberculosis in contingents of adults MBT+; in Murmansk, Pskov and Leningrad region it includes the modern preventive measures. For St.-Petersburg all directions of antitubercular work will be equally significant
