Antimicrobial Activity of Wild Plant Seed Extracts against Human Bacterial and Plant Fungal Pathogens

Five wild plant species belonging to different families (Chenopodium album, Plantago major, Elytrigia elongata, Filipendula ulmaria and Nigella sativa) widely spread in Russian Federation and the former USSR were evaluated for their ability to inhibit growth of two important human food-borne pathogens (Escherichia coli O157:H7 and Listeria monocytogenes strain EGD-e) and eight plant pathogens (Alternaria alternata, Alternaria tenuissima, Bipolaris sorokiniana, Stagonospora nodorum, Fusarium solani, Fusarium oxysporum, Fusarium culmorum and Phytophtora infestans). To isolate biologically active compounds from seeds, a step-wise procedure including extraction with hexane, ethyl acetate, ethanol, and 10% acetic acid followed by reversed-phase HPLC was developed. Using disc-diffusion assay, the highest activity against E. coli O157:H7 was observed with extracts from F. ulmaria (hexane and ethyl acetate extracts and the unbound RP-HPLC fraction) and P. major (ethyl acetate extract and the unbound RP-HPLC fraction);E. elongate (the unbound RP-HPLC fraction) was less active. The extracts from P. major and E. elongate (the unbound RP-HPLC fractions) were equally highly active against L. monocytogenes, while those of F. ulmaria (the unbound RP-HPLC fraction) and N. sativa (hexane and ethyl acetate extracts) were less active against this pathogen. The dynamics of L. monocytogenes EGD-е and E. coli O157:H7 growth in the presence of two most potent extracts (RP-HPLC-unbound fractions of P. major and E. elongate and the hexane extract of F. ulmaria) was studied.

Characterization and Identification of Two Opportunistic Human Bacterial Pathogens in Rice

Burkholderia cepacia （Bc） and Pseudomonas aeruginosa （Pa） are both biocontrol agents in agriculture and opportunistic human pathogens in hospitals. Effective management and utilization practice is needed to understand their characteristics and distribution in rice. During the last decade, the two opportunistic human pathogens were detected in 631 samples of rice seed and 117 samples of rice plant in plain, highland and mountainous rice growing areas of China. Bc and Pa were primarily differentiated by common bacteriological characteristics and pathogenic tests and then identified into species by Biolog and FAME tests. However, the genotypes of Bc still could not be distinguished. It has been noted that the Bc and Pa mainly existed in rice root with the highest distribution frequency in plain areas （ 6.1% and 16.1%） and lowest in the mountainous areas （1.0% and 7.8%）.

Methods:Antibacterial assay was carried out by using disc diffusion method,determination of minimum inhibitory concentrations(MIC) and minimum bactericidal concentrations(MBC) against five strains of Gram-positive and seven strains of Gram-negative human pathogenic bacterial strains.Results:The results of antibacterial activity of Vitex species showed that the extracts possessed a broad spectrum of antibacterial activity.The V.peduncularis possessed the highest activity against all the microorganisms screened.It produced a zone of inhibition ranged between (11.000±0.577) and(22.670±0.667) mm and the MIC values were from 62.5 to I 000.0μg/mL and the MBC values were from 125.0 to 2 000.0μg/mL.Conclusions:Based on the present study, V.peduncularis is recommended for the isolation of antibacterial molecule responsible for the activity against the tested human pathogenic bacterial strains.

Prevalence and Seroprevalence of Non-SARS Human Coronaviruses 229E and OC43 in East Tyrol/Austria

The recent SARS-CoV-2 pandemic renewed interest in other previously discovered human coronaviruses—the non-severe acute respiratory syndrome human coronavirus (non-SARS hCoVs) and this study is a starting point for a closer investigation of those. With the pandemic behind us we believe it to be important to also examine the current and past respiratory pathogen landscape in the patient population in our care. Therefore, 954 nasopharyngeal swabs of patients with respiratory diseases collected between October 2018 and March 2020 were tested against the pathogens Mycoplasma pneumoniae, Bordetella pertussis, Influenza A and virus, Human metapneumovirus, respiratory syncytial virus, Parainfluenza virus, human Adenovirus and Polyoma virus BK/JC. Swabs negative against these pathogens were further tested for OC43 and 229E by RT-qPCR. Human coronaviruses 229E and OC43 were proven as the causative agents in a considerable number of cases, confirmed by PCR. Overall, our results show that those two non-SARS hCoVs were responsible for 13.9% (11 of 79) of infections with flu-like symptoms of unknown etiology in the study area. In the subsequent seroprevalence study, it was shown that the seroprevalence rate of IgG antibodies against 229E and OC43 was over 50%, indicating that a big part of the population in our study area has been in contact with these non-SARS-CoVs and has built the specific humoral immune response accordingly.

施肥旱作农田土壤中人类病原菌群落组成及动态变化特征

采集浙江省杭州、嘉兴、衢州、金华、龙游5个地区长期施用鸡粪、猪粪或化肥的农田土壤进行室内培养实验,然后采用高通量测序及序列比对方法分析供试土壤细菌和人类病原菌(human pathogenic bacteria,HPB)群落组成,旨在进一步探究施用粪肥后土壤中HPB群落组成差异及动态变化特征。结果表明:在160个供试土壤样品和2种粪肥样品中共比对到75种HPB,其中优势HPB为巨大芽孢杆菌(Bacillus_megaterium_QM_B1551,24.2%)和拜氏梭菌(Clostridium_beijerinckii_NCIMB_8052,23.1%);施用猪粪处理的土壤中细菌和HPB的香农(Shannon)指数均有所降低,而施用鸡粪或化肥处理的土壤中细菌和HPB多样性无明显变化。主坐标分析结果表明,施用粪肥处理的土壤细菌群落组成与未施肥对照之间具有显著差异,尤其是施用猪粪处理差异最显著(P<0.001);土壤样品间共有HPB占所有HPB的22.7%;施用粪肥处理的土壤中大部分HPB的相对丰度高于未施肥对照,并随培养时间的延长而不断下降。方差分解分析结果表明,土壤理化性质、细菌群落及两者交互作用是土壤中HPB变异的重要因素。综上所述,施用粪肥处理的土壤中HPB的变化特征主要受肥料类型、土壤类型、土壤理化性质及固有细菌群落的影响。

Viral hepatitis and human immunodeficiency virus coinfections in Asia

Hepatitis B virus(HBV), hepatitis C virus(HCV),and human immunodeficiency virus(HIV) affect many people in Asian countries, although there are geographic differences. Both HBV and HIV(HBV/HIV) and HCV/HIV co-infections are highly prevalent in Asia. Hetero- and homosexual, injection drug use, and geographic area are strong predictors of HBV, HCV, and HIV serostatus. In HBV endemic regions, the prevalence and genotype distribution of HBV/HIV coinfection is almost comparable with that in the general population. In Japan, where HBV has low endemicity, the prevalence of HBV/HIV co-infection is approximately 10-fold higher than that in the general population, and HBV Ae is the most common subgenotype among HIV infected individuals. Highly active antiretroviral therapy(HAART) is an effective treatment for HIV/Acquired Immune Deficiency Syndrome. Lamivudine, a component of HAART, is an effective treatment for HBV, HIV, and HBV/HIV co-infection; however, cost, emerging drug resistance, antiretroviral-associated liver toxicity and liver-related morbidity due to HCV progression are particular concerns. HCV/HIV co-infection may accelerate the clinical progression of both HCV and HIV. The high prevalence of HBV/HIV and HCV/HIV co-infections in Asia underscores the need to improve prevention and control measures, as fewer evidencebased prevention strategies are available(compared with Western countries). In this review, the most recent publications on the prevalence of HBV/HIV and HCV/HIV co-infections and related issues, such as therapy and problems in Asia, are updated and summarized.

Quantum dot biosensor combined with antibody and aptamer for tracing food-borne pathogens

Due to the increasing number of food-borne diseases,more attention is being paid to food safety.Food-borne pathogens are the main cause of food-borne diseases,which seriously endanger human health,so it is necessary to detect and control them.Traditional detection methods cannot meet the requirements of rapid detection of food due to many shortcomings,such as being time-consuming,laborious or requiring expensive instrumentation.Quantum dots have become a promising nanotechnology in pathogens tracking and detection because of their excellent optical properties.New biosensor detection methods based on quantum dots are have been gradually developed due to their high sensitivity and high specificity.In this review,we summarize the different characteristics of quantum dots synthesized by carbon,heavy metals and composite materials firstly.Then,attention is paid to the principles,advantages and limitations of the quantum dots biosensor with antibodies and aptamers as recognition elements for recognition and capture of food-borne pathogens.Finally,the great potential of quantum dots in pathogen detection is summarized.

Comparative prevalence of pathogenic and spoilage microbes in chicken sausages from Egypt and Greece

This study investigated the spread of foodborne pathogens: Listeria monocytogenes, Es-cherichia coli O157:H7, Staphylococcus aureus and Salmonella in chicken sausage samples collected from retail markets in Greece and Egypt during 2006 and from Egypt through 2010. Other microbiological parameters;total viable count (TVC), lactic acid bacteria (LAB), pseudomonads (PS), staphylococci (STAPH), Brochothrix thermosphacta (BT), Enterobacteriaceae (EN), Escherichia coli (EC), yeasts and moulds (Y&M) were also counted. Egyptian chicken sausage samples were found to harbor L. mono- cytogenes, Staph. aureus and E. coli O157:H7;with frequencies equivalent to 24%, 60% and 26% of the total samples during 2006 and 37.87%, 64.44% and 41.11% of the total samples during 2010, respectively, while Greek samples were entirely free of theses pathogens. Enrichment techniques indicated the absence of Salmonella from both Greek and Egyptian samples. The obtained results may mobilize food producers and handlers in developing countries to take the due measures reducing food-borne pathogen risks and spoilage flora alongside the poultry chain.

人腺病毒致病机制研究进展

腺病毒(AdV)在自然界分布广泛,全球各国家或地区均有AdV感染出现。科学家于1953年初分离出AdV至今,已发现100多种血清型,可分成哺乳动物AdV和禽类AdV两属。依据AdV抗血清中和的能力,可将人腺病毒(HAdV)分成71种不同的血清型;结合生物学和免疫学特性又将其划分为A~G 7个亚群。AdV可感染上呼吸道、肺、结膜、泌尿道和胃肠道,引起相应部位的炎症,少数则表现为肝炎、胰腺炎、肾炎、出血性结肠炎、出血性膀胱炎、脑膜脑炎,在免疫功能低下的患者常可引起严重甚至致死性感染,因此对人类的健康造成了极大的威胁。本文以HAdV对机体的致病展开综述,讨论了AdV对人体致病的多种作用机制,并提出对HAdV未来致病机制与免疫逃逸研究的展望,并根据其新兴研究提出对新型抗HAdV药物开发的展望。

动物粪便对紫色土中人类致病菌传播的影响

畜禽粪肥进入土壤会促进抗生素耐药性的传播,在传播过程中一旦人类致病菌获得抗生素耐药性,将对人类健康造成巨大威胁。本研究采用高通量测序技术,探究施加猪粪或鸡粪肥后紫色土中致病菌水平及其与抗生素抗性基因的共生关系。结果表明,与未施肥土壤相比,施加粪肥可明显改变土壤细菌群落结构。施加猪粪土壤中的致病菌丰度显著高于施加鸡粪土壤与未施肥土壤。施加粪肥后土壤中致病菌丰度随培养时间增加而减少,可能与土壤生态系统本身的自我净化功能有关。羊布鲁氏杆菌、毕氏梭菌、产气荚膜梭菌与多种抗生素抗性基因显著相关。致病菌相对丰度变化与细菌群落结构有显著相关关系(P<0.01)。细菌群落与土壤理化性质对致病菌相对丰度变化的解释率可达70.6%,可知二者是造成致病菌相对丰度变化的主要因素。综上所述,施加畜禽粪便可增加土壤中致病菌丰度与多样性,同时致病菌与多种抗生素抗性基因存在共生关系。

Hyperoncotic human albumin solutions for intravenous fluid therapy: Effectiveness of pathogen safety and purification methods, and clinical safety

Albumin solutions derived from human plasma have demonstrated clinical benefits as intravenous fluid therapy in clinical settings such as liver disease,sepsis,intensive care,and surgery.For all plasma-derived medicinal products,there is a potential risk from pathogens,including relevant blood-borne viruses,emerging viruses,and prion proteins.To minimize the risk of transmissible infections,the production of human albumin solutions includes rigorous donor selection and plasma testing,and effective pathogen removal and inactivation methods such as fractionation and pasteurization.Compliance with international pharmacopeial standards for purity and prekallikrein activator and aluminum content is crucial,as is post-marketing pharmacovigilance for the continuous monitoring of adverse events.This review focuses on the effectiveness of manufacturing methods in the production of plasma-derived albumin,to ensure the safety of hyperoncotic solutions for volume expansion.We evaluated evidence identified through online database(PubMed)searches and from unpublished sources,on the manufacturing and pathogen safety of plasma-derived albumin solutions.The results confirmed the already established and evolving pathogen reduction capacity of the reviewed manufacturing methods.Up-to-date post-marketing pharmacovigilance data and log 10 reduction factors for known and emerging pathogens during albumin production are included.Towards the goal of ever-increasing clinical safety,potential areas of improvement,such as compliance rates for the completion of donor health questionnaires,are also discussed.Taken together,the current manufacturing and pathogen reduction steps result in albumin products of greater purity than previous-generation products,with a high margin of pathogen safety against known and emerging pathogens,such as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).
