Title: A novel microfluidic biosensor for rapid detection of foodborne bacteria
Time : 10:10-10:30
Biography:
Xuan Weng’s primary research focus on Microfluidics and Lab-on-a-Chip in the fields of biomedical, food safety and environmental monitoring for the point-of-care (POC) applications. Within this work frame, she has conducted many projects on microfluidic system development towards portable devices capable of rapid, accurate, automated detection and raw-sample-to-result capabilities.
Abstract:
Vibrio parahaemolyticus is one of the foodborne bacteria that widely present in seafood as well as the leading cause of seafood-associated bacterial gastroenteritis. Traditional identification of such pathogens mainly relies on culturing methods, ELISA or PCR. These methods are usually laborious, time-consuming with poor diagnosis competences, or require costly and bulky equipment though of high sensitivity. In this project, we proposed a thread-based microfluidic electrochemical biosensor for rapid and accurate detection of V. parahaemolyticus in pure culture and raw food sample.
Threads were used to fabricate the microchannel network as well as the electrodes for the electrochemical measurement. The V. parahaemolyticus aptamer functionalized MoS2 nanosheets were immobilized on the thread-based electrodes for selective sensing. A variation in charge on the surface of the electrode can be generated by the interaction between targeted bacteria and specific aptamer. The presence of targeted bacteria would result in decreased current output and the decreasing degree of which is associated with the concentration of the targeted bacteria in the sample. When used in detecting Vibrio parahaemolyticus, the proposed biosensor had a dynamic detection range of 10–106 CFU mL−1 with a detection limit of 5.74 CFU mL−1.
Compared with traditional plate counting method, the proposed biosensor had higher detection sensitivity and less assay time (30 min), while high specificity and accuracy are kept. It can be concluded that the proposed thread-based electrochemical biosensor provides a rapid, easy-to-use, low cost and accurate method for the detection of foodborne bacteria, and it is promising for point-of-care and on-field assay. For the future developments of such microfluidic electrochemical biosensor, emphasis can be placed on the optimization of the conjugation protocol and binding chemistry of bio-receptors with viable nanomaterials to further enhance the sensitivity while withstanding regeneration conditions, multiplexed detection, regeneration of the used biosensor, integration of on-chip sample preparation unit, etc.

Abstract:
Background: The wide distribution of T. gondii infection makes finding a safe and effective drug a great success. Current therapeutics do not clear parasite infection and are hampered by severe adverse effects.
Aim: The present study was carried out to investigate the effect of chitosan nanoparticles (CS NPs), spiramycin, spiramycin co-administered with metronidazole and spiramycin-loaded CS NPs on the parasite load and histopathology in the liver, spleen and brain in Swiss albino mice infected with acute T. gondii (RH strain).
Materials and methods: Seventy male Swiss albino mice were divided into seven equal groups: healthy control (I), infected untreated control (II), infected group receiving CS NPs (III), infected group treated with spiramycin (IV), infected group treated with spiramycin-metronidazole (V), infected treated with spiramycin-loaded CS NPs 400 mg/kg (VI) and infected treated with spiramycin-loaded CS NPs 100 mg/kg (VII). All mice were inoculated intraperitoneally with 2500 T. gondii tachyzoites RH strain except the healthy control group. Mice were sacrificed on the 8thday for liver, spleen and brain parasite load and histopathological studies.
Results: Parasite load and histopathological examination of liver, spleen and brain of all treated mice revealed decrease in the inflammation, congestion, necrosis and mean tachyzoites count within tissue sections. Spiramycin-loaded NPs showed the highest significant reduction in the pathological insult while spiramycin alone revealed the lowest reduction as compared to the other used drugs. Administration of either CS NPs or spiramycin-metronidazole induced a moderate reduction in the pathological changes.
Conclusion: Based on the present research, it can be concluded that spiramycin-loaded CS NPs lead to a pronounced decrease in tachyzoites count and histopathological effects compared to the other used treatments. Thus, spiramycin-loaded CS NPs is a promising synergistic formulation in the treatment of acute toxoplasmosis.

Title: Co-existance of mobile colistin resistance (mcr) gene in carbapenem resistant bacterial isolates from Delhi, India
Biography:
Firdous currently works at Microbiology Research Lab, Jamia Millia Islamia, New Delhi, India as Ph.D student. He has done M.Sc Biochemistry from University of Kashmir. His research is antimicrobial resistance and current focus is molecular detection of genetic factors and their diversity conferring Colistin resistance, a last resort drug against infections caused by Carbapnemase and ESBL producing Enterobacteriaceae. He is awarded Senior Research Fellowship from Indian Council of Medical Research (ICMR), Bill and Melinda Gates foundation scientist travel award for World Microbe Form from ASM and FEMS, and young researcher award from Scholars of India (InSc).
Abstract:
Antibiotic resistance is a significant global health concern. Apart from fundamental applications in clinical settings, antibiotics are extensively used in agriculture, food industry and aquaculture. Presence of antibiotics in the ecosystem, serves a potent stimulus to elicit a bacterial adaptation response to develop antibiotic resistance. Increased use of colistin, a last resort drug due to failure of Carbapenems has possibly contributed in development and spread of resistance to colistin among Enterobacteriaceae. The colistin belongs to the family of Polymyxins, cationic lipopeptides, with broad-spectrum activity against Gram negative bacteria. In this study we obtained 370 non-duplicate bacterial isolates from sewage water and river Yamuna in Delhi and phenotypically screened for colistin resistance. Of the 59 positive isolates colistin resistance gene mcr-1 was detected among 10 isolates. Chromosomal based genes phoPQ, pmrAB and mgrB were amplified from 5 resistant isolates of Klebsiella pneumoniae; sequencing confirmed 4 isolates with wild type genotype but 1 isolate revealed missense mutation in mgrB and phoQ in phoPQ two component system. Moreover, carbapenem resistant genes blaNDM-5, blaVIM, OXA were also detected in mcr-1 postive bacterial isolates. ESBL determinants blaCTX-M, blaSHV and blaTEM were present in colistin resistant bacteria. Furthermore, group specific analysis of CTX-M reveals presence of CTX-M-1 and CTX-M-25 among them. Antibiotic susceptibility test of all isolates against 9 different classes of drugs revealed multidrug resistant phenotype with high MIC values. In vitro transconjugation studies showed successful transfer of mcr-1 and other ESBL resistant determinants. Results of our conjugation studies further highlight the risk for dissemination of mcr-1 gene and other resistant determinates to other bacteria including clinically important pathogens.

Abstract:
Background: The novel severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) infection has appeared in China, in December 2019, then other countries all around the globe including Iran had encounters with this infection. Early symptoms of COVID-19 such as fever, sore throat, cough, illness, rhinorrhea, diarrhea, vomiting, stomach pain are analogous between children and adults. We have designed this study to prediction of severity in hospitalized children.
Method: This multi-central cross sectional study was carried out from March 2020 to October 2020, on 238 hospitalized confirmed COVID-19 paediatric cases in several major educational paediatric hospitals in 4 citys: Tehran, Ahwaz, Isfahan, and Bandar Abbas. Medical records about epidemiologic data, past medical history, underlying diseases, symptoms, para-clinical data and treatment information were all collected in standardized forms.
Results: 38% of all patients had at least one underlying disease. 41% of patients had a history of contact with suspected or confirmed cases and 11% had participated in gatherings. Among these hospitalized patients, 59% had pulmonary involvements and 12 cases (5%) were expired. In our study, the use of antibiotics and antivirals in hospitalized children with a diagnosis of COVID-19 is 82% and 39%, respectively and also, the most prevalent clinical symptoms were fever (73%),cough(39%),vomiting(29%),diarrhea(18%), and myalgia(13%).
Conclusion: Evaluation of SGOT, CRP, ALC, LDH, WBC, O2sat, Ferritin levels in children with COVID-19 can be an indication for hospitalization, and a predictor of disease severity, helping out clinicians in the management of patients.

Abstract:
Statement of the Problem:. Existing tests for SARS-CoV-2 like PCR slow, expensive and and the case of lateral flow insensitive. There is a need for better for flash testing and variants.
Findings: Our method detects the early immune response by looking at variation in the leucocyte ratios, a methods that we publisehed in the peer reviewed press in 2020.
Using training data from the COVID-19 Risk and Treatments (CORIST) collaboration and the Moli-Sani Project, both from southern Italy, comprising WBC differential data for 72 positive (RT-PCR confirmed) and 4742 negative COVID patients, respectively, two variations of the test were applied. Algorithmic ensemble CLDC 21-04- SE optimized for sensitivity has a sensitivity of 97·29% and specificity of 67·95%. Algorithmic ensemble 21-04-SP has a sensitivity of 81·82% with a specificity of 96·50%.
Using data from the Regional Service for the Epidemiology and Surveillance of Infectious Diseases database, a longitudinal cohort study of 379 patients with laboratory-confirmed COVID-19 admitted at the Italian National Institute for Infectious Diseases “Lazzaro Spallanzani” (INMI), in Rome (Italy). The 21-04-SE algorithm showed a sensitivity of 98·64% during the first seven days during symptom onset and 96·73% sensitivity for data taken over 21 days after initial symptoms. The 21-04-SP algorithm showed a sensitivity of 79.0%.
Conclusion & Significance:
We have a robust repeatable test for SARS-CoV2 with a turnaround time of 30 seconds for a self-test from patient presenting to getting a positive or negative result. The ability to turn around tests very rapidly and de-skill the data collection promises to have a massive impact on COVID worldwide. The fact that no test laboratory is needed, just a smartphone, and the tests can be carried out by an unskilled individual gives a huge improvement.

Title: Assessing putative interplay between human herpesvirus-6 infection and alcohol abuse in Substantia nigra
Biography:
Currently Samanta Strojeva is studying for a master's degree at the University of Latvia, Faculty of Biology. Last year, she successfully defended her bachelor 's thesis about "Involvement of HHV-6 infection and proinflammatory cytokines in autoimmune thyroiditis development". Next year Samanta Strojeva will defended her master’s thesis about SARS-CoV-2. For almost 2 years she is working in RÄ«ga Stradiņš University as a senior laboratory assistant. In March 2021, Samanta Strojeva successfully defended her thesis in RSU research week 2021 about “Formation of SARS-CoV-2 specific antibodies in dynamics”. At the moment, she is working in fundamental and applied research project of the Latvian Council of Science 2020/2-0069 “The role of human herpesvirus-6 infection and alcohol abuse in the development of neuroinflammation”.
Abstract:
The previous studies have demonstrated that the central nervous system (CNS) is particularly vulnerable to alcohol induced changes, for example, alcohol increases the risk of Parkinson’s disease by affecting Substantia nigra (SN). Also called the “Black Substance”, it is the dopaminergic neurons rich part of the basal ganglia located in the midbrain.
Human herpesvirus-6 (HHV-6) is a linear double stranded DNA virus, infection is ubiquitous and can induce various neurological diseases. HHV-6 replicates most efficiently in activated primary T cells, however, studies show that the virus can also replicate in a wide array of host cells, for example in monocytes, macrophages, astrocytes, oligodendrocytes and neurons. The aim of the study is to detect the presence of HHV-6 in SN region of chronic alcoholics and healthy individuals.
Post mortem tissue samples of SN grey and white matter from 42 individuals (control group, age matched alcoholics and non-age matched alcoholics) were analysed in this study. DNA was extracted using blackPREP FFPE DNA kit. To detect viral genomic sequences and variant, we were using nPCR technique. Viral loads were detected using HHV-6 Real-TM Quant kit. Fluorescent immunohistochemical staining and confocal microscopy were applied.
The presence of HHV-6 DNA was detected in 19,05% (8/42) of the SN region. All positive HHV-6 FFPE tissue samples were from alcoholic individuals. In white matter HHV-6 was detected in 62,5% (5/8), and in grey matter – 87,5% (7/8) out of HHV-6 positive cases. All control individuals were HHV-6 negative. HHV-6B variant was detected in all positive individuals. Viral load was detected in the one alcoholic individuals’ white matter – 101207,97 copies/1x106 cells. HHV-6 immunopositivity was detected in both grey and white matter.
These findings provide evidence that HHV-6 can integrate and replicate in the SN region. In addition, the evidence from this study shows then the potential role of HHV-6 and alcohol use may affect brain homeostasis.

Cancer Research Institute, Slovakia
Title: Identification of a new coronavirus in rectal swabs 15-30 days after overcoming the infection
Biography:
Vladimir Zajac has completed his PhD. in 1982 at the Cancer Research Institute of Slovak Academy of Sciences in Bratislava (Slovakia), where he worked as the Head of Department of Cancer Genetics from 1996 to 2010. He joined the Medical Faculty of the Comenius University as Associate Professor of Genetics in 2007. He has published 74 papers mostly in reputed journals and he was editor of the book Bacteria, viruses and parasites in AIDS process“ (In Tech, 2011).
Abstract:
Every virus is a parasite that cannot exist on its own and is fully dependent on its carrier. This is the basic condition of its existence. The parasite must have its host, and thus is a living cell, but it is generally claimed that the virus can exist without a carrier for 2 to 5 seconds, during which it is transmitted to another species. The primary carrier, however, cannot be host organ cells because they could easily damage them. In terms of the mechanism of existence and transmission, the following could be the most suitable carriers of the virus: bacteria, yeast or other single-cell organisms. Based on work with bovine leukosis virus (BLV) in the stables, we monitored the course of infection in healthy animals and concluded that a bacterial cell can be the host of the virus. We tested this assumption and confirmed the results. This idea was then tested on the HIV model n the laboratory of Prof. Flossie Wong-Staal, UCSD. Even with this virus, we have been able to prove that its host may be bacteria, or yeasts.
Based on our achieved results and inventions, rectal swabs were taken from persons who overcame the infection with a new coronavirus at the Institute of Clinical Microbiology at the Faculty Hospital Nitra (Slovakia) under the leadership of Prof. MUDr. Anna Liskova, PhD. The obtained results confirm that out of a cohort of 30 tested persons, only five patients (17%) did not show signs of presence of the novel coronavirus in their stool more than 12-30 days after overcome the infection, as proven by RT PCR tests. The remaining 25 subjects (83%) still had presence of coronavírus in their stool more than 12-30 days after overcome the infection. The results show that most patients still have the virus in their stool, ie in the intestinal tract, after overcoming the infection. Under optimal conditions, the new coronavirus can multiply and expand from the host. The wearer thus becomes an infectious, which can infect other people. This process very probably represents the second wave of infection. It is therefore recommended that these people strictly adhere te necessary hygiene. Strict adherence to the recommended measures will radically reduce the number of newly infected people and victims.
The detection of the novel coronavirus in the intestinal tract of people who overcame the infection 2-4 weeks before being tested raises a fundamental question: in what form does the virus exist in the tract? A virus such as a parasite cannot exist on its own, cannot reproduce and cannot be transmitted to another organism. It therefore must have a carrier. So, what carriers does the virus use to persist in the intestinal tract, but also throughout the body? Can they be bacteria or yeast, or some other single or multicellular organisms? By identifying the carrier or carriers of the virus and their subsequent elimination, we also eliminate the virus. And that may bring the epidemic to its end.

Abstract:
One Health is global and has to be respected as the biggest threats are the emerging zoonotic diseases. We will encounter more often the biothreats as we travel more and with an increasing dense population f the world, the spread of infectious diseases goes faster and over a bigger area. The recent outbreak of SARS-CoV-2 is a an example of an emerging pathogen, which has spread all over the world. This nasty virus is discovered in humans almost two years ago and has created a lot of fear and economic damage.
It is of utmost importance to do research on the new emerging contagious diseases and to keep biosafety and biosecurity well organised in the laboratories where this research is done. To train the biothreat awareness and biological management is very important.
Tools to monitor, detect and identify the threat of new emerging zoonotic diseases is getting more important together with diagnostic tools for the diagnosis of the victims of new pandemic causing pathogens.
Classical microbiological identification techniques are too slow or unspecific for prompt reaction on an outbreak of an new emerging disease, which is at that moment unknown. To detect ‘pathogenicity islands’ in a virus or bacterium is more important in this phase than to identify the organism. The zoonotic micro-organism most probably is mutated naturally or in a laboratory and therefor not identifiable with existing ‘classical’ techniques.
New gene-extraction techniques and new analysers, which give a kind of fingerprint of the threat, are developed and these new techniques will be important to monitor the safety of the environment.

Researcher in the University of São Paulo, in the Ophthalmology department from 2012 to 2013.Author of the theory Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine. Author of more than 40 publications about treatment of variety of diseases rebalancing the internal energy using Hippocrates thoughts.
Abstract:
Statement of the Problem:
There are many articles in the literature demonstrating that the epidemiology of infectious disease did not evolve from a single discipline but from a complex scientific views. From 19 to 20th century, old concepts have been revised and new ideas have been added.
Purpose:
To demonstrate that patients that have infectious disease have energies deficiencies in the chakras’ energies centers that are causing weakness state of the immune system Leading to a weak Zheng-Qi in traditional Chinese medicine. This lack of energy is inducing the formation of internal Heat, that is the energy imbalance leading to the formation of internal Fire, resulting in the adherence of bacteria in the cells and systems and the treatment using antibiotics is only treating the manifestation of the disease as like the tip of the iceberg but the root of the problem is not still being treated.
Methods:
Through articles that the author published regarding treatment of variety of infectious disease , including community and hospital infections , all without using any antibiotics, she is demonstrating in all her articles that the infections are only the manifestations of internal energy disharmonies and the treatment only rebalancing all these energies, through the use of correct diet according to Chinese dietary nutrition and the use of auricular acupuncture associating with apex ear bloodletting and replenishing the chakras’ energy centers with homeopathies medications, according to the theory Constitutional Homeopathy of the five Elements Based on Traditional Chinese Medicine were enough to treat this infections
Results:
All treatments including community and nosocomial infections proposed by the author, only rebalancing the internal energies of Yin, Yang, Qi and Blood and taking out the internal Heat, was done with success without the need of using any antibiotics.
Conclusion:
The conclusion of this study is that patients with signs and symptoms of infections have energy deficiencies behind the infectious symptoms and the treatment of these energy imbalances using Chinese dietary counseling ,auricular acupuncture associating with apex ear bloodletting and replenishing the energies using homeopathies medications according to the theory Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine are very important tools that the physician can use nowadays, in patients with infectious diseases symptoms.
