Abstract:

ABSTRACT In central nervous system (CNS) infectious and inflammatory diseases of known cause, oligoclonal bands represent antibody directed against the causative agent. To determine whether disease-relevant antibodies can be cloned from diseased brain, we prepared an antibody phage display library from the brain of a human with subacute sclerosing panencephalitis (SSPE), a chronic encephalitis caused by measles virus, and selected the library against SSPE brain sections. Antibodies that were retrieved reacted strongly with measles virus cell extracts by enzyme-linked immunosorbent assay and were specific for the measles virus nucleocapsid protein. These antibodies immunostained cells in different SSPE brains but not in control brain. Our data provide the first demonstration that diseased brain can be used to select in situ for antibodies directed against the causative agent of disease and point to the potential usefulness of this approach in identifying relevant antibodies in chronic CNS or systemic inflammatory diseases of unknown cause.

Abstract:

The Apiaceae are a large plant family consisting of approximately 250 genera and over 3,000 species grown worldwide. Its representative vegetables are carrot, parsley, parsnip and celery, as well as some wellknown spice plants such as fennel, anise, caraway, dill, and coriander. Their production is imperiled by numerous pathogens, among which viruses are of great importance. Globally more than 30 viruses are known to affect carrot and other plant species belonging to family Apiaceae. The principal viruses are: Celery mosaic virus (CeMV), Parsnip yellow fleck virus, (PYFV), Carrot red leaf virus (CtRLV) and Carrot mottle virus (CMoV). In Serbia, three viruses are present on carrot and celery: CeMV, Cucumber mosaic virus (CMV) and Tomato spotted wilt tospovirus (TSWV). The economic importance of viruses infecting umbelliferous has long been recognised due to the foliar symptoms and viral dieback of seedlings. These viruses affect carrot crops only sporadically, but when they do occur they can be devastating. Other umbelliferous viruses are known to occur worlwide, however, their effects are not clear.

Abstract:

Emerging viral diseases encompass two types, those of new appearance in the population and those that we previously knew about or re-emerging, but that at a certain moment present an exponential increase in incidence or geographic distribution in the form of epidemics or outbreaks. These emerging and re-emerging viruses share a series of characteristics that establish the emerging virus model, such as having an RNA genome, being zoonotic, transmitted by vectors and transmissible to humans, that the virus is able to recognize and provoke a response in receptors. Conserved in several species and inhabiting ecosystems that undergo ecological, demographic or social changes that favor the spread of the virus. There are different factors that contribute to facilitating the emergence of viral infections, although this is made up of three fundamental aspects such as the susceptible population, the virus itself and the environment where both can interact.

Abstract:

Viral diseases are an important limiting factor in many crop production systems. Because antiviral products are not available, control strategies rely on genetic resistance or hygienic measures to prevent viral diseases, or on eradication of diseased crops to control such diseases. Increasing international travel and trade of plant materials enhances the risk of introducing new viruses and their vectors into production systems. In addition, changing climate conditions can contribute to a successful spread of newly introduced viruses or their vectors and establishment of these organisms in areas that were previously unfavorable. Tomato is economically the most important vegetable crop worldwide and many viruses infecting tomato have been described, while new viral diseases keep emerging. Pepino mosaic virus is a rapidly emerging virus which has established itself as one of the most important viral diseases in tomato production worldwide over recent years. Begomovirus species and other whitefly-transmitted viruses are invading into new areas, and several recently described new viruses such as Tomato torrado virus and new Tospovirus species are rapidly spreading over large geographic areas. In this article, emerging viruses of tomato crops are discussed.

Abstract:

Presented review of rose diseases, associated with the mosaic symptoms, includes common and yellow rose mosaic, rose ring pattern, rose X disease, rose line pattern, yellow vein mosaic and rose mottle mosaic disease. Based on symptomatology and graft transmissibility of causing agent many of those rose disorders are called "virus-like diseases" since the pathogen has never been identified. However, several viruses were detected and identified in roses expressing mosaic symptoms. Currently the most prevalent rose viruses are Prunus necrotic ringspot virus - PNRSV, Apple mosaic virus - ApMV (syn. Rose mosaic virus) and Arabis mosaic virus - ArMV Symptoms and damages caused by these viruses are described. Tomato ringspot virus, Tobacco ringspot virus and Rose mottle mosaic virus are also mentioned as rose pa thogcns. Methods of control of rose mosaic diseases are discussed.

Abstract:

Viral diseases are the important diseases next to the fungal and bacterial in Nepal. The increase in incidence and severity of viral diseases and emergence of new viral diseases causes the significant yield losses of different crops in Nepal. But the research and studies on plant viral diseases are limited. Most of the studies were focused in viral diseases of rice (Rice tungro virus and Rice dwarf virus), tomato (Yellow leaf curl virus) and potato (PVX and PVY). Maize leaf fleck virus and mosaic caused by Maize mosaic virus were recorded as minor disease of maize. Citrus Tristeza Virus is an important virus of citrus fruit in Nepal while Papaya ringspot potyvirus, Ageratum yellow vein virus (AYVV), Tomato leaf curlJava betasatellite and Sida yellow vein Chinaalphasatellite were recorded from the papaya fruit. The Cucumber mosaic virus (CMV) and Zucchini yellow mosaic potyvirus (ZYMV) are the viral diseases of cucurbitaceous crop reported in Nepal. Mungbean yellow mosaic India virus (MYMIV) found to infect the many crops Limabean, Kidney bean, blackgram and Mungbean.

Abstract:

Introduction. The end of 20th and beginning of 21st century is marked by the discovery of new, supercontagious and fast spreading viral diseases. Since 1967, more than 40 new agents have been identified, including human immunodeficiency virus, Ebola, Marburg fever, severe acute respiratory syndrome, hepatitis C, hepatitis E viruses and Zika virus. Modern lifestyle, availability and speed of air traffic, migrations, as well as climate changes, enable faster spreading of infectious diseases from the regions that were hardly reachable. We selected a few diseases that raised the greatest attention among experts and public in general. Ebola. Ebola virus raises anxiety due to high mortality and fast spreading by using inter-human contact. Zika virus. Zika virus, that most often causes mild symptoms, is potentially responsible for microcephaly in neonates. Dengue. Dengue virus is an ?old story?, but in last decades incidence has multiplied by 30. West Nile virus. Although discovered in 1937, West Nile virus has been found exclusively in rural parts of Africa, while nowadays it represents one of the most important etiological factors of viral meningo-encephalitis all over the world. Hepatitis E. Today it is well-known that hepatitis E virus can cause not only acute viral hepatitis but also potentially blood-transmitted chronic hepatitis in immunocompromised, as well as some neurological disorders. Conclusion. One of the scientific challenges in the future will certainly be the discovery of available and cost-effective diagnostic tests, as well as efficient and safe vaccines for these diseases. Up to now, efficient prophylaxis is available only for Denga virus.

Abstract:

Human life is intricately related to its surrounding environment which also harbors other animals and some deadly infectious pathogens. Any threat to the environment can thus increase the threat of new and so-called emerging infectious diseases (EIDs) especially novel viral infections called emerging viral diseases. This occurs partly due to changing climate as well as human interference with nature and animal life. An important event in new disease emergence is genetic changes in the pathogen that make it possible to become established in a new host species, productively infect new individuals in the new hosts (typically humans) and create local, regional or worldwide health threats. The world has witnessed some emerging and deadly viral threats in recent past with huge mortality and morbidity. Among them were severe acute respiratory syndrome (SARS), bird flu, swine flu, Middle East respiratory syndrome (MERS), ebola virus disease. Moreover some disease has caused great concern in certain regions including Bangladesh in terms of morbidity, like Nipah virus, Zika virus, Dengue and Chikungunya fever. Here in this article an attempt was made to briefly describe some of these emerging viral infections.Birdem Med J 2017; 7(3): 224-232

Abstract:

Болезнь, вызванная вирусом Эбола (БВВЭ) — одно из самых высоколетальных вирусных заболеваний, поражающих человека и приматов. Возбудителем БВВЭ является вирус Эбола. В настоящее время известно шесть видов этого вируса, три из них патогенны для человека — это виды Заир (ZEBOV), Судан (SUDV) и Бундибугио (BDBV), вызывающие острые вирусные высоконтагиозные лихорадки у людей и приматов с летальностью до 90%. В большинстве случаев БВВЭ вызвана видом ZEBOV. Разработка вакцин против БВВЭ началась сразу после идентификации возбудителя в 1976 г. На сегодняшний день в мире зарегистрировано четыре вакцинных препарата для профилактики БВВЭ. Все они основаны на протективном антигене — гликопротеине (GP) вируса Эбола вида ZEBOV. В силу того, что виды SUDV и BDBV также могут быть причиной вспышек и эпидемий БВВЭ, очевидна необходимость разработки вакцин, способных обеспечить защиту от всех известных патогенных для человека видов вируса Эбола. В статье систематизированы данные относительно структуры, иммуногенных и протективных свойств GP вируса Эбола, проведен анализ иммунодоминантных эпитопов гликопротеина вирусов ZEBOV, SUDV и BDBV, необходимых для формирования протективного иммунитета, а также предложен рациональный, на наш взгляд, подход создания возможных вариантов вакцин против БВВЭ, вызванной разными видами вируса Эбола, состоящий в использовании векторных конструкций, экспрессирующих как минимум два варианта гликопротеина — GP вируса Эбола вида ZEBOV и вида SUDV.

Abstract:

Plant viruses cause severe damage and significant economic losses to agriculture. Control of virus usually consist of the elimination of virus vectors (insects, nematodes, fungi, etc), improvement of the sanitary status of the propagation material, the use of resistance sources in breeding programs. The application of the pathogen-derived resistance strategy has opened new avenues to protect plants against viruses. Two molecular mechanisms seem to underlie the engineered protection, the virus transgene-derived protein and the transgene-RNA interference. A few examples that support the efficiencies of these two molecular mechanisms are reviewed here and discussed in light of the potential use of virusresistant transgenic plants in agriculture.

Abstract:

The genus Cucurbita comprises many popular vegetable and ornamental plants, including pumpkins, squashes, and gourds, that are highly valued in China as well as in many other countries. During a survey conducted in Zhejiang province, Southeast China in 2016, severe symptoms of viral infection were observed on Cucurbita maxima Duch. ex Lam. Diseased plants showed symptoms such as stunting, mosaicking, Shoe string, blistering, yellowing, leaf deformation, and fruit distortion. Approximately, 50% of Cucurbita crops produced in Jinhua were diseased, causing an estimated yield loss of 35%. In this study, we developed a method using all known virus genomes from the NCBI database as a reference to map small RNAs to develop a diagnostic tool that could be used to diagnose virus diseases of C. maxima. 25 leaf samples from different symptomatic plants and 25 leaf samples from non-symptomatic plants were collected from the experimental field of Jihua National Agricultural Technology Garden for pathogen identification. Small RNAs from each set of three symptomatic and non-symptomatic samples were extracted and sequenced by Illumina sequencing. Twenty-four different viruses were detected in total. However, the majority of the small RNAs were from Zucchini yellow mosaic virus (ZYMV), Watermelon mosaic virus (WMV), and Cucumber mosaic virus (CMV). Mixed infections of these three viruses were diagnosed in leaf samples from diseased plants and confirmed by reverse transcription PCR (RT-PCR) using primers specific to these three viruses. Crude sap extract from symptomatic leaf samples was mechanically inoculated back into healthy C. maxima plants growing under greenhouse conditions. Inoculated plants developed the same disease symptoms as those observed in the diseased plants and a mixed infection of ZYMV, WMV, and CMV was detected again by RT-PCR, thus fulfilling Koch’s postulates. The diagnostic method developed in this study involves fewer bioinformatics processes than other diagnostic methods, does not require complex settings for bioinformatics parameters, provides a high level of sensitivity to rapidly diagnose plant samples with symptoms of virus diseases and can be performed cheaply. This method therefore has the potential to be widely applied as a diagnostic tool for viruses that have genome information in the NCBI database.

So far, members of this family have been identified in birds and mammals. Until 2006, BK virus (BKV), JC virus (JCV), and simian virus 40 (SV40) were the only polyomaviruses known to circulate in the human population. Their occurrence in individuals was mainly confirmed by PCR and the presence of virus-specific antibodies. Using the same methods, lymphotropic polyomavirus, originally isolated in monkeys, was recently shown to be present in healthy individuals although with much lower incidence than BKV, JCV, and SV40. The use of advanced high-throughput sequencing and improved rolling circle amplification techniques have identified the novel human polyomaviruses KI, WU, Merkel cell polyomavirus, HPyV6, HPyV7, trichodysplasia spinulosa-associated polyomavirus, and HPyV9. The skin tropism of human polyomaviruses and their dermatopathologic potentials are the focus of this paper.

Abstract:

Opium poppy (Papaver somniferum L.) is described in the literature as a natural host of turnip mosaic virus, bean yellow mosaic virus, beet yellows virus and beet mosaic virus, and experimental host of plum pox virus. P. orientale L., a natural host of beet curly top virus, was successfully infected with turnip mosaic virus and cucumber mosaic virus, and P. dubium L. with turnip mosaic virus. P. rhoeas L. is a natural host of turnip mosaic virus, and artificial host of beet yellows, plum pox and cucumber mosaic viruses. P. nudicaule is reported as a natural host of beet curly top, tomato spotted wilt viruses and turnip mosaic, experimentally it was infected with turnip mosaic virus. Eschscholtzia californica Cham. is described as a natural host of aster yellows phytoplasma, and experimental host of bean yellow mosaic virus. In the Czech Republic, only turnip mosaic virus was reliably identified in naturally infected P. somniferum.

Abstract:

Sweetpotato is an important staple food crop in Sub-Saharan Africa, with production being concentrated in East Africa, particularly around Lake Victoria. Productivity of the crop is greatly constrained by viral diseases. Four main viruses have consistently been detected from various surveys done in the region viz. sweet potato feathery mottle virus (SPFMV), sweet potato chlorotic stunt virus (SPCSV), sweet potato mild mottle virus (SPMMV), and sweet potato chlorotic fleck virus (SPCFV). Sweet potato caulimo-like virus (SPCaLV), sweet potato latent virus (SPLV), and cucumber mosaic virus (CMV) have also been detected though only in isolated cases. The most severe symptoms have been caused by co-infection with SPCSV and SPFMV, resulting in the synergistic Sweet potato virus disease (SPVD). Yield reductions due to virus infections have been estimated to be >90% in very severe cases. Virus detection has mainly been limited to the use of serological methods. Some plants have been observed with symptoms resembling those caused by viruses, but do not react with available antisera, indicating that the plants could be infected with viruses that have not been described, or not tested in the region. Use of other detection techniques such as PCR may result in identification of more viruses in the region. This report gives a summary of our research efforts towards detection of other viruses present in the region, and identification of resistant germplasm.

Abstract:

Viral RNA genomes change shape as virus particles disassemble, form replication complexes, attach to ribosomes for translation, evade host defense mechanisms, and assemble new virus particles. These structurally dynamic RNA shapeshifters present a challenging RNA folding problem, because the RNA sequence adopts multiple structures and may sometimes contain regions of partial disorder. Recent advances in high resolution asymmetric cryoelectron microscopy and chemical probing provide new ways to probe the degree of structure and disorder, and have identified more than one conformation in dynamic equilibrium in viral RNA. Chemical probing and the Detection of RNA Folding Ensembles using Expectation Maximization (DREEM) algorithm has been applied to studies of the dynamic equilibrium conformations in HIV RNA in vitro, in virio, and in vivo. This new type of data provides insight into important questions about virus assembly mechanisms and the fundamental physical forces driving virus particle assembly.

Abstract:

Sunflowers (Helianthus annuus L.) are susceptible to multiple diseases in field production. In this study, we collected diseased sunflower leaves in fields located in South Dakota, USA, for virome investigation. The leaves showed visible symptoms on the foliage, indicating phomopsis and rust infections. To identify the viruses potentially associated with the disease diagnosed, symptomatic leaves were obtained from diseased plants. Total RNA was extracted corresponding to each disease diagnosed to generate libraries for paired-end high throughput sequencing. Short sequencing reads were assembled de novo and the contigs with similarities to viruses were identified by aligning against a custom protein database. We report the discovery of two novel mitoviruses, four novel partitiviruses, one novel victorivirus, and nine novel totiviruses based on similarities to RNA-dependent RNA polymerases and capsid proteins. Contigs similar to bean yellow mosaic virus and Sclerotinia sclerotiorum hypovirulence-associated DNA virus were also detected. To the best of our knowledge, this is the first report of direct metatranscriptomics discovery of viruses associated with fungal infections of sunflowers bypassing culturing. These newly discovered viruses represent a natural genetic resource from which we can further develop potential biopesticide to control sunflower diseases.

Abstract:

Virus diseases of berry plants became more common and harmful in the 1960s, when berry cultivation expanded in Finland. Virus diseases seldom occur in strawberry because the main vector, Chaetosiphon fragaefolii, does not thrive in Finland. However NEPO-viruses are found in Finland in plant nurseries and in berry cultivations, and they may become a danger for strawberry as well as for raspberry growing. Both wild and cultivated raspberries are commonly infected by viruses. The vector aphids also occur in Finland. Reversion disease infects black currants. The veinbanding virus disease is common in red currants and gooseberries. Virus diseases of berries are poorely investigated in Finland. The healthy plant propagation and certification scheme was established in the 1970s. More research is needed in order to understand our virus problems, to develop proper test methods, and to prevent virus spread.
