Legionella bacteria are ubiquitous in environmental waters. Only a few species of Legionella , especially, L. pneumophila are pathogenic to humans and cause a sometimes fatal Legionnaires disease as well as a less fatal disease called Pontiac fever. The presence of Legionella in sewage and aerosolized sewage is the subject of this investigation because reuse of sewage may involve the exposure of people to aerosolization, the mode of transmission of Legionella bacteria. The objective of this study was to determine the prevalence of Legionella species and L. pneumophila in wastewater and their fate after various stages of treatment. The polymerase chain reaction (PCR) and standard culture method were utilized to detect Legionella species and L. pneumophila. PCR results indicated that Legionella species were present at levels > 103 cells / ml during all phases of sewage treatment including chlorinated effluents. Culture results indicated levels at least one log lower than seen with PCR. Legionella species were also recovered from air samples collected from secondary aeration basins at levels < 103 cells/ml. PCR was shown to be the most rapid and sensitive method for detecting Legionella in sewage.

Absolute dependence onmecA gene as the defining standard in determining the resistance ofS. aureusto methicillin became the subject of distrust by many researchers. The present study aimed to determine the frequency ofmecA gene in methicillin resistantS. aureus(MRSA) isolates using polymerase chain reaction and to correlate its presence to conventional method. In this regard, two hundredS. aureusisolates were collected from patients with different diseases attending different hospitals in Shandi City, Sudan. Phenotypic Kirby-Bauer method confirmed the existence of methicillin resistantS. aureusin 61.5% of the subjected isolates with MICs ranging from 4 μg/mL to 256 μg/mL when usingE-test. However, when amplifying a 310 bp fragment of themecA gene by PCR, twelve out of the 123 MRSA isolates (9.8%) weremecA negative, whereas all the 77 methicillin sensitiveS. aureus(MSSA) weremecA negative. In conclusion, this study drew attention to the credibility of themecA gene and its usefulness in the detection of all MRSA strains without referring to the traditional methods. Hence, it is highly recommended to consider alternative mechanisms forβ-lactam resistance that may compete withmecA gene in the emergence of MRSA phenomenon in the community.

Relevance. Every year, dog breeders are faced with the problem of acute poisoning of dogs. Various toxic compounds can be the cause of dog poisoning. The huge variety of potentially toxic substances makes it difficult to identify the source of poisoning. Service dog breeding also faces this problem, as a result of which it is necessary to have information about the possibility of poisoning service dogs, as well as methods for detecting toxic substances and preventing further poisoning. In service dog breeding, they mainly use feed made by cooking gruel soup in boilers in the feed kitchens of nurseries. Due to the fact that there were cases of poisoning of service dogs in the Vyborg district of the Leningrad region, we conducted research to identify toxic compounds in beef from which feed was made in the feed kitchens of nurseries.Methods. The studies were carried out at the Institute of Toxicology of the Federal Medical and Biological Agency using an Acguity UPLC I-class ultra-performance liquid chromatograph with a spectrophotometric detecto and an Acguity UPLC H-class ultraperformance liquid chromatograph with a Xevo TQD tandem mass spectrometer. Sample components were identified by electronic spectra and mass numbers.Results. According to the results of the study, the presence of isoniazid metabolic products in the form of isonicatinic acid, as well as conjugates of isoniazid with sulfuric, acetic and glucuronic acids, was found in beef meat.The obtained results of the study of the chromatographic profiles of aqueous extracts and the chemical identification of their components in the products that are used for the preparation of food for service dogs make it possible to accurately determine and identify toxic substances with a wide variety of them. Thus, in order to prevent the loss of service dogs, it is necessary to control the newly received food and feed in order to prevent poisoning.

Проблема и цель. Целью данной работы являлось генотипирование животных по генам CAST и CAPN1 c выявлением частот генотипов и аллелей, а также тестирование продукции этих животных, выраженное в оценке выдержанного в течение 8 суток мяса, на показатели, составляющие нежность, сочность, органолептическую оценку вкуса. Методология. Объектом исследований являлись бычки кроссов брединского мясного типа симменталов, полученные от использования выдающихся быков-производителей канадских мясных симменталов на отечественных матках различных линий. Для осуществления полимеразной цепной реакции (ПЦР) по тиражированию участка генома, составляющего ген CAPN1316 и ген CAST2857, использовались праймеры, найденные в открытой печати и синтезированные в фирме «Синтол». Проводилась оценка мяса на нежность (сопротивление усилию на разрез прибором Уорнера-Братцлера + органолептическая оценка варёного и жареного мяса), сочность (p/h, с использованием прокалывающего электрода LoT406-M6-DXK-S7/25 + влагоудерживающая способность). Результаты. В результате показатели мяса бычков, имеющих сочетание генотипов TT* по CAST и СС* по CAPN1, имели превосходство над средними показателями общей выборки (P< 0,001); а также над имеющей наибольшее распространение в выборке группой животных с желательным генотипом СС по гену CAPN1 на 1,22 балла или 15,4 % (P< 0,01) по нежности; на 1,44 балла или 18,2 % (P< 0,05) по сочности; на 1,56 балла или 19,2 % (P< 0,001) по вкусу. Заключение. Таким образом, исследования подтвердили влияние полиморфного состояния гомозиготы СС гена CAPN1 само по себе, а также генов CAST и CAPN1 на нежность говядины в той её части, когда сочетание генотипов ТТ в гене CAST и СС в гене CAPN1 даёт положительный эффект по нежности говядины, вероятно связанный с активизацией деятельности μ-кальпаина в связи с ослаблением влияния кальпастатина как ингибитора на μ-кальпаин. Problem and purpose.The aim of this work was to genotype animals for the CAST and CAPN1 genes with identifying the frequencies of genotypes and alleles, as well as testing the products of these animals, expressed in assessing meat aged for 8 days, for indicators that make up tenderness, juiciness, and organoleptic taste assessment.Methodology. The object of research was the bulls of the breeds of the Bredy meat type of simmentals obtained from the use of outstanding bulls-producers of Canadian meat simmentals on domestic females of various lines. To carry out the polymerase chain reaction (PCR) for replicating a region of the genome constituting the CAPN1316 gene and the CAST2857 gene, primers found in the open press and synthesized by Syntol were used. The meat was evaluated for tenderness (resistance to cutting force with a Warner-Bratzler device + sensory evaluation of cooked and fried meat), juiciness (p/h, using a piercing electrode LoT406-M6-DXK-S7/25 + water-holding capacity). Results. As a result, the meat indicators of bulls with a combination of TT * genotypes for CAST and CC * for CAPN1 were superior over the average indicators of the total sample (P <0.001), as well as over the most common group of animals in the sample with the desired CC genotype for the CAPN1 gene by 1.22 points or 15.4% (P <0.01) for tenderness, 1.44 points or 18.2% (P <0.05) for juiciness, 1.56 points or 19.2% (P <0.001) for taste. Conclusion. Thus, the studies have confirmed the influence of the polymorphic state of the CC homozygote of the CAPN1 gene itself, as well as of the CAST and CAPN1 genes, on the tenderness of beef in that part of it when the combination of TT genotypes in the CAST gene and CC in the CAPN1 gene has a positive effect on the tenderness of beef, probably associated with the activation of the activity of μ-calpain due to the weakening of the effect of calpastatin as an inhibitor on μ-calpain.

Introduction . High prostate cancer (PC) incidence rates testify to importance of research into genesis of the given disease and means of its prevention. The item of oncogenic human papillomaviruses (HPVs) participance in PC origination is still being the subject of debates. If association of PC with HPV is proven prophylaxis of the given disease becomes possible by means of inoculating boys with the vaccines made for cervical cancer (CC) prevention.Objective: to test whether prostate tissues surgically removed from PC patients harbor oncogen E7 of HPV18 – the second most common HPV type responsible for CC.Materials and methods . The study was carried out on prostate glands of 17 PC patients surgically treated in N.N. Blokhin National Medical Research Center of Oncology. Detection of HPV18 oncogen E7 was done by polymerase chain reaction. To elevate polymerase chain reaction sensitivity DNA was isolated from homogeneous cell populations collected by means of microdissections from cryopreserved PC specimens.Results . Amplification products corresponding to HPV18 oncogen E7 were registered in tests from 2 PC patients.Conclusion . HPV18 oncogen E7 was detected in surgically removed prostate tissues of 2 PC patients. In the aggregate with our previous result (7 HPV16-positive PC cases in the same group of 17 patients) the given result enables one to presume participance of oncogenic HPVs in PC genesis. The problem deserves further study.

At the end of 2019, coronavirus disease-2019 (COVID-19) started to spread worldwide and caused a pandemic in March 2020. Epidemiologic data of COVID-19 in the pediatric population are not certain. The pandemic also decreases routine immunization coverage in children which lead to increased risk of vaccine-preventable disease outbreak. Routine immunization practice should be continued with due regard to health protocol. Children in contact with COVID-19 patients or children who previously have COVID-19 may be immunized after 14 days of symptom-free or confirmed negative by two polymerase chain reaction tests at a minimum interval of 24 h. Bacillus Calmette–Guerin, influenza, and pneumococcal immunization give a positive effect on COVID-19. Until present, there is no available vaccine for COVID-19.

Background: The most malignant form of infiltrating astrocytoma, glioblastoma multiforme (GBM), is one of the most aggressive human cancers. Foretinib diminished GBM cell invasion by downregulating the expression of matrix metalloproteinase 2 (MMP2). Aim: The study aimed to examine the anti-tumor activity of foretinib and to test its effect on MMP2 expression in T98 cells. Materials and Methods: T98 cells were used as an experimental model of glioblastoma. The effect of foretinib on the expression of MMP2 was evaluated using quantitative real-time polymerase chain reaction. Thereafter, the effect of foretinib on the enzyme levels of MMP was examined by zymography. Statistical analyses were performed with GraphPad Prism software. Results: A reduction in the expression of MMP2 was observed with an increase in the concentration of foretinib. Conclusion: Foretinib treatment leads to downregulation of MMP-2 and has a positive effect on T98 cells. We believe that foretinib can be subjected to further clinical investigation to develop a treatment for GBM.

Emergent infectious diseases represent a major threat for biodiversity in fragmented habitat networks, but their dynamics in host metapopulations remain largely unexplored. We studied a large community of pathogens (including 26 haematozoans, bacteria and viruses as determined through polymerase chain reaction assays) in a highly fragmented mainland bird metapopulation. Contrary to recent studies, which have established that the prevalence of pathogens increase with habitat fragmentation owing to crowding and habitat-edge effects, the analysed pathogen parameters were neither dependent on host densities nor related to the spatial structure of the metapopulation. We provide, to our knowledge, the first empirical evidence for a positive effect of host population size on pathogen prevalence, richness and diversity. These new insights into the interplay between habitat fragmentation and pathogens reveal properties of a host–pathogen system resembling island environments, suggesting that severe habitat loss and fragmentation could lower pathogen pressure in small populations.

In situ hybridization (ISH) with biotin-labeled probes is increasingly used in histology, histopathology and molecular biology, to detect genetic nucleic acid sequences of interest, such as viruses, genetic alterations and peptide-/protein-encoding messenger RNA (mRNA). In situ polymerase chain reaction (PCR) (PCR in situ hybridization = PISH) and the new in situ self-sustained sequence replication-based amplification (3SR) method even allow the detection of single copies of DNA or RNA in cytological and histological material. However, there is a number of considerable problems with the in situ PCR methods available today: False positives due to mis-priming of DNA breakdown products contained in several types of cells causing non-specific incorporation of label in direct methods, and re-diffusion artefacts of amplicons into previously negative cells have been observed. To avoid these problems, super-sensitive ISH procedures can be used, and it is well known that the sensitivity and outcome of these methods partially depend on the detection system used.
