The modern data of the world scientific literature on resistance to a wide range of insecticides from different chemical groups, concerning natural populations of the most epidemiologically significant species of blood-sucking mosquitoes belonging to the three genera Aedes, Culex, Anopheles, are presented. Most studies are carried out according to the recommendations of the World Health Organization method ("bottle test"). The distribution of resistance is patchy across regions and may vary within a country. A number of genetic mutations responsible for the development of resistance have been described. Keywords: blood-sucking mosquitoes, resistance, insecticides, mosquito Vectors,
本文介绍了伊蚊、库蚊、按蚊三属中最具流行病学意义的吸血蚊子自然种群对不同化学类群的多种杀虫剂的抗药性的现代世界科学文献资料。大多数研究是根据世界卫生组织建议的方法("瓶试验")进行的。耐药性在各区域的分布是不完整的,在一个国家内也可能有所不同。已经描述了一些导致耐药性发展的基因突变。关键词:吸血蚊;抗药性;杀虫剂;

Hydrogen peroxide has a wide range of applications and has high antimicrobial activity, but it is a caustic substance and its effect leads to tissue damage, so controlling its content in the air is an important scientific task. In this article the peculiarities of hydrogen peroxide application for aerosol disinfection of the air are considered The special equipment intended for air disinfection, depending on its technical equipment and software, allows different modes of hydrogen peroxide application. The main focus of this work has been on studying the drop in concentration of hydrogen peroxide to a safe level. The modes of application of the units at different temperatures as well as natural and forced ventilation have been considered. Keywords: hydrogen peroxide, toxicity, inhalation, TVL, aerosol air disinfection.

In the context of the coronavirus pandemic, one of the priority tasks is the disinfection of environmental objects in order to comply with the anti-epidemic regime. In this regard, questions arise regarding the laboratory control of the effectiveness of disinfection measures. The use of virological approaches is hardly acceptable for solving this problem, and the use of fast and affordable methods of molecular genetic analysis comes to the fore, which are certainly of signal value, but sufficient to evaluate the effectiveness of these measures. In this work, studies were carried out on the detection of SARS-CoV-2 coronavirus RNA by several test systems using the real-time polymerase chain reaction method in swabs from various surfaces after they were treated with a disinfectant. The study showed that to control the decontamination of environmental objects potentially infected with the SARS-CoV-2 coronavirus, test systems can be used to detect the RNA of the SARS-CoV-2 virus in clinical samples. The greatest sensitivity is shown for PCR kits in which multichannel detection of individual RNA sites is carried out. Keywords: disinfectants, decontamination control, novel coronavirus infection COVID-19.
在新型冠状病毒大流行的背景下,为遵守防疫制度,对环境物体进行消毒是一项优先任务。在这方面,出现了关于消毒措施有效性的实验室控制的问题。使用病毒学方法很难解决这一问题,使用快速和负担得起的分子遗传分析方法脱颖而出,这当然具有信号价值,但足以评估这些措施的有效性。在这项工作中,研究了几种检测系统在不同表面的拭子经消毒剂处理后,使用实时聚合酶链反应法检测SARS-CoV-2冠状病毒RNA。研究表明,为了控制对可能感染SARS-CoV-2冠状病毒的环境物体的去污,可以使用测试系统检测临床样本中的SARS-CoV-2病毒RNA。灵敏度最高的是PCR试剂盒,其中对单个RNA位点进行多通道检测。关键词:消毒剂;去污控制;新型冠状病毒感染

In order to detect antibodies to hantaviruses – pathogens of hemorrhagic fever with renal syndrome selectively over 2 periods: (80-90s of the 20th century and 2006-2016), the population of 21 districts of the region and the city of Ulyanovsk was examined. Sera were examined by indirect immunofluorescence (RNIF). The obtained results indicate changes in the loymopotential of natural foci of hemorrhagic fever with renal syndrome, which is confirmed by the indicators of the immune layer and the incidence of the population in the studied territories. It has been shown that the epidemic potential of natural foci of hemorrhagic fever with renal syndrome in the Ulyanovsk region is determined by the nature of the landscape. The risk of infection of the population is maximum in the zone of broad-leaved forests, minimal in the agricultural (steppe) landscape. Keywords: hemorrhagic fever with renal syndrome, immune layer, landscape.
为了在两个时期(20世纪80-90年代和2006-2016年)选择性地检测汉坦病毒抗体-肾综合征出血热病原体,对该地区21个地区和乌里扬诺夫斯克市的人口进行了检查。采用间接免疫荧光法(RNIF)检测血清。所得结果表明肾综合征出血热自然疫源地的血势发生了变化,免疫层指标和研究地区人群发病率证实了这一点。研究表明,乌里扬诺夫斯克地区肾综合征出血热自然疫源地的流行潜力是由景观性质决定的。人口感染的风险在阔叶林区最大,在农业(草原)景观最小。关键词:肾综合征出血热,免疫层,景观。

This review describes nanosized particles of metals, oxides and organic substances that can act as effective disinfectants when irradiated with ultraviolet and visible light. Such an effect is due to photocatalytic action, namely the release of reactive oxygen species, leading to oxidative stress in pathogenic microflora. The review gives a description of the physical and chemical principles of such particles, the variety of their types, methods of their synthesis, and examples of their application. The data from the articles of the last few years from the leading international scientific journals are cited and promising directions for further work are outlined. Keywords: titanium dioxide, zinc oxide, copper oxide, nanopowders, nanoparticles, photocatalysts, reactive oxygen species (ROS), antimicrobial properties, resistance, oxidative stres.

The morbidity of human lice in the Russian Federation in 2016–2021 was analyzed. High intensive infection rates were registered in the Central, Northwestern and Far Eastern Federal Districts. The maximum level of pediculosis infestation of the population was noted in Moscow (88.7–96.1 % of all cases of this disease in the Central Federal District). The resistance of lice to permethrin led to a decrease in the pediculicidal activity of pediculicides based on it. The range of modern drugs effective against permethrin-resistant head and body lice and the dynamics of the ratio of pediculicides based on substances from different groups of insecticides during 1991–2021 were analyzed. Keywords: pediculosis, Pediculus humanus, resistance, pyrethroids, pediculicides.

Annual submissions regarding ixodic ticks suction are registered in Khabarovsk. The research presents data of entomological observations of ixodic ticks population as well as their infection rate with tick-borne infections in the Khabarovsk city and its rural zone. Circulation of six epidemiologically significant species of Ixodidae family ticks that belong to three genus were detected in natural and anthropogenically transformed biocenoses of the Khabarovsk city and its rural area: Ixodes (I. persulcatus, I. pavlovskyi), Haemaphysalis (H. japonica, H. concinna) and Dermacentor (D. silvarum, D. reticulatus). Study revealed that I. persulcatus ticks were infected as well as greater number of tick-borne infections pathogens were isolated in this tick species, which specifies their high epidemiological significance. The fact of discovery of new types of carriers necessitates studies for evaluation of their infection rate and clarification of their role as tick-borne infection vectors. Keywords: ixodic ticks, infection rate, tick-borne infections, rural zone, urban environment.
在哈巴罗夫斯克登记了有关吸蜱的年度提交。该研究提供了哈巴罗夫斯克市及其农村地区蜱虫种群的昆虫学观察数据以及它们与蜱媒感染的感染率。在哈巴罗夫斯克市及其农村地区的自然和人为转化的生物群落中,发现了6种具有流行病学意义的伊蚊科蜱虫,分别是伊蚊(persulcatus、pavlovskyi)、血蜱(H. japonica、H. concinna)和革蜱(D. silvarum、D. reticulatus)。研究结果表明,该蜱属感染过硫蜱,且分离出较多的蜱传感染病原体,具有较高的流行病学意义。由于发现了新型带菌者,有必要进行研究,以评估其感染率并澄清其作为蜱传感染媒介的作用。关键词:蜱,感染率,蜱传感染,农村,城市环境。

In a review of foreign literature, the issues of biological methods for controlling synanthropic cockroaches, including the use of entomopathogenic fungi such as Metarhizium and Beauveria, are considered, due to high biodegradability and species-specificity, is a potential alternative to the chemical method. It has been shown that the combination of chemical and biological agents in cockroach control can slow down the emergence of insect resistance and enhance the insecticidal effect. The densonucleosis viruses BgDNV and PfDNV may be required for the biological control of cockroaches due to such features as rapid replication, high specificity, and pathogenicity for the host. In view of the close relationship between symbiotic microorganisms and host physiology, insect control strategies using transgenic symbionts have become the subject of research. Significant differences in the composition of the intestinal microbiota between the pyrethroid-resistant and insecticide-susceptible strains of the German cockroach were found. A new potential direction for insect resistance management has been identified. Keywords: entomopathogenic fungi, German cockroach, microbiota, symbiotic microorganisms.
在对国外文献进行综述的基础上,认为利用绿僵菌和白僵菌等昆虫病原真菌防治合胞蜚蠊具有较高的生物可降解性和物种特异性,是化学方法的潜在替代方法。研究表明,化学药剂与生物药剂相结合防治蟑螂,可以减缓昆虫抗药性的产生,提高杀虫效果。由于BgDNV和PfDNV具有复制速度快、特异性高、对宿主致病性强等特点,可能需要对蟑螂进行生物防治。鉴于共生微生物与寄主生理的密切关系,利用转基因共生体防治昆虫已成为研究的课题。发现德国蜚蠊对拟除虫菊酯耐药株和对杀虫剂敏感株的肠道菌群组成存在显著差异。发现了抗虫管理的一个新的潜在方向。关键词:昆虫病原真菌,德国蜚蠊,菌群,共生微生物
