The Importance Of Bioaerosol In Forensic Investigations

<abstract xmlns="http://www.w3.org/1999/xhtml">Brucellosis is a transmissible bacterial zoonotic disease caused by Gram-negative coccobacillus bacteria of the genus <italic>Brucella.</italic> The disease severely hinders the livestock industry and human health. In several instances, infected animals act as carriers for the cross-species transmission of brucellosis. Social issues, poor husbandry practices, irregularities in the marketing and movement of domestic animals, and lack of coordination between veterinary and human health services are some of the key factors responsible for the transmission and prevalence of Brucellosis. Human contact with infected domestic animals is often the transmission route of Brucellosis infection. Therefore, human brucellosis could be eradicated globally by eradicating animal brucellosis. This review describes the current status of brucellosis and the risk factors of the disease in animals and the human population. In addition, there is a further discussion of the various issues related to the control and prevention of brucellosis in domestic animals and humans.1. Introduction. 2.

<abstract xmlns="http://www.w3.org/1999/xhtml">Bacterial proteins of the Dsb (disulfide bond) system catalyze the formation of disulfide bridges, a post-translational modification of extra-cytoplasmic proteins, which leads to stabilization of their tertiary and quaternary structures and often influences their activity. DsbA – <italic>Escherichia coli</italic> monomeric oxidoreductase is the best studied protein involved in this process. Recent rapid advances in global analysis of bacteria have thrown light on the enormous diversity among bacterial Dsb systems. The set of Dsb proteins involved in the oxidative pathway, varies, depending on the microorganism. In this article we have focused on characterization of structural and phylogenetic groups of monomeric DsbAs. This review discuss their physicochemical features and interactions with redox partners as well as with substrate proteins. The last part of the review concentrates on dimeric oxidoreductases responsible for disulfide generation. Many virulence factors are the substrates of the Dsb proteins. Thus unraveling the machinery that introduces disulfide bonds and expanding knowledge about Dsb protein structures and their activities may facilitate the discovery of an effective anti-bacterial drugs.1.

<abstract xmlns="http://www.w3.org/1999/xhtml">Lyme disease is a multisystem disease caused by bacteria belonging to the group <italic>Borrelia burgdorferi</italic> sensu lato. The vector that carries the infection is a tick of the genus <italic>Ixodes</italic>, that infects subsequent hosts of the spirochete during blood-meal. The varied course of Lyme disease makes it impossible to recognize it on the basis of clinical symptoms. Therefore, the diagnosis of Lyme disease is based mainly on laboratory methods, both direct (detection of the presence of DNA or infectious agent proteins in the biological material collected from the patient) and indirect (mainly serological tests). A commonly recommended approach is serodiagnosis, however, due to the time required for the body to produce specific antibodies, it is not useful in the earliest period of infection. Microbiological diagnostics also can not be used to diagnose Lyme disease in the first weeks of the disease due to its low sensitivity and long waiting time for the result. The solution seems to be molecular diagnostics based on the detection of the spirochete DNA using PCR reaction that is highly specific and sensitive. However, the effectiveness of this approach depends on many factors, therefore it is necessary to develop a standardized protocol ensuring reproducibility of results in all laboratories.1.

Advancements of Microbiology

 The Advancements of Microbiology (formerly Postępy Mikrobiologii) is a quarterly of the Polish Society of Microbiologists. The journal was founded in 1961, initially under the patronage of the Microbiology Committee of the Polish Academy of Sciences, and in 1989 it became the organ of the PSM. The following professors have served as Editors-in-Chief of Postępy Mikrobiologii during the period: Prof. Edmund Mikulaszek 1962 – 1972, Prof. Władysław Tomasz Dobrzański 1972 – 1982, Prof. Zdzislaw Ilczuk 1983 – 1991, Prof. Jerzy Hrebenda 1991 – 2009, Prof. Jacek Bielecki 2009 – 2022. Journal implements the Society’s main goals, like promoting the development of microbiological sciences, popularizing the achievements of microbiology among members of the Society and broad circles of readers.   Advancements of Microbiology is topical journal for scientists in several microbiological fields and often the place where the first works of young researchers are published. Advancements of Microbiology include review articles from all areas of microbiology that are not printed in other journals. Please send manuscripts with attachments to the editor's e-mail address: editorial.office@am-online.org   Due to the great thematic diversity of the articles sent to the editorial office, it is not possible to print monographic volumes. Most of the papers currently published in Advancements of Microbiology are review articles in the field of bacterial physiology, microbial genetics, environmental microbiology, applied microbiology and virology; the work in the field of epidemiology, classification and identification of bacteria and applications of molecular biology techniques in microbiological research are particularly extensive.   The editors of Advancements of Microbiology strive to print works – ordered by eminent scientists – regarding currently fashionable problems of modern science. We especially encourage Authors to write articles in the field of their expertise, which guarantees the highest scientific level. The high scientific level of the journal was reflected in the progress of the JCR citation index and the presence of our journal on the Philadelphia list. It is especially important for young Authors, for whom Advancements of Microbiology often open the way to a scientific career. The current activity of Advancements of Microbiology is based mainly on publishing reviews related to the latest scientific achievements in the field of microbiology, which, at present is characterized by unusual dynamics of development and comprehensive application possibilities. The selection of current and relevant research topics and their presentation at a high scientific level in our journal is the basis for the existence of the quarterly, Advancements of Microbiology.

Professor Odo Feliks Kazimierz Bujwid (1857 – 1942) – was the first Polish bacteriologist, who graduated from the University of Warsaw and gained experience in Berlin working with Robert Koch, and in Paris at the Ludwik Pasteur Institute.   The Polish Society of Microbiologists (PSM), formerly the Polish Society of Microbiologists and Epidemiologists, was established in Warsaw on October 31, 1927 at the first Congress of Polish microbiologists. Professor Zygmunt Szymanowski was elected the first President of PSM. The same year, PSM also became cofounder of Federation of European Microbiological Societies (FEMS) and since 2005 PSM is a member of European Society of Clinical Microbiology and Infectious Diseases (ESCMID).   Within over 95 years of activity, 29 Congresses of PSM were organized and 16 professors were elected as Presidents of PSM. About 900 ordinary members and 19 honorary members, associated in 14 PSM branches all over Poland, belong to the Society.   The aims of PSM have been the same since its very beginnings: to promote the development of microbiological sciences and to popularize the achievements of microbiology among the Society’s members and the broad public. PSM organizes congresses, scientific meetings, courses and lectures and competitions of scientific papers. Two quarterly journals, the Polish Journal of Microbiology and the Advancements in Microbiology are issued by PSM. The Society formulates opinions on the conditions and needs of Polish microbiology and applies in these cases to the state authorities; cooperates with related associations in the country and abroad.   Archiving   Sciendo archives the contents of this journal in Portico – a digital long-term preservation service of scholarly books, journals and collections.   Plagiarism Policy   The editorial board is participating in a growing community of Similarity Check System’s users to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
