A comparison of actual and expected dinucleotide frequencies of the 16 dinucleotides in coding regions of the CHIKV was also undertaken. 2013ZX10004-217, and No. Schematic representation of the E2 envelope glycoprotein. Immediately report incident to supervisor, complete an employee incident report in PeopleSoft. Such understanding may be applied in order to anticipate future epidemics and reduce the incidence by development and application of, for example, vaccination and antiviral therapy. Vector Borne Zoonotic Dis. 11:304. doi: 10.3389/fimmu.2020.00304 Liposomal Delivery of the RNA Genome of a Live-Attenuated Chikungunya Virus Vaccine Candidate Provides Local, but Not Systemic Protection After One Dose Therefore, we constructed a corresponding relation distribution plot between the ENC and GC3 values. The mean CAI value was low, indicating low codon usage bias and expression levels, which agreed with the ENC analysis. In the case of A. albopictus, the strongest effect was noted on the ECSA genotype, followed by Asian and WA genotypes. A possible explanation for the weak codon bias of RNA viruses is that it might be advantageous for efficient replication in host cells, with potentially distinct codon preferences [21]. CHIKV: chikungunya virus; Ct: cycle threshold; DENV: dengue virus. Therefore, from the similarity index analysis, we observed that selection pressure from hosts and vectors have contributed to shaping the molecular evolution of CHIKV at the level of codon usage. Found insideThis edited book, "Nucleic Acids - From Basic Aspects to Laboratory Tools", contains a series of chapters that highlight the development and status of the various aspects of the nucleic acids related to DNA chemistry and biology and the ... In this paper, we summarize the current knowledge of CHIKV genomic organization, cell tropism, and the virus replication cycle, and evaluate the possibility to predict its future evolution. The similarity index D(A,B) was therefore calculated for each genotype of CHIKV in relation to its hosts and vectors. When these plots were accessed on regional basis, it was found that different genotypes are circulating in single country. Outbreaks have occurred in countries in Africa, Asia, Europe, and the Indian and Pacific Oceans. Alternative codons within the same group coding for the same amino acid are often termed ‘synonymous’ codons, although their corresponding tRNAs might differ in their relative abundance in cells and in the speed by which they are recognized by the ribosome. This book is a systematic and concise resource useful to anyone involved with or looking to move into aquaculture and fisheries. As the first to focus exclusively on alphaviruses, this timely book serves as an invaluable resource for researchers and clinicians working with alphaviruses and related viruses. Solid front gown with tight fitting wrists and respiratory protection. Inflammation & Immunology. Our analysis shows that mutational pressure has played a major role in shaping the dynamics of codon usage patterns within CHIKV genomes. MABF2052, is a mouse monoclonal antibody that detects E2 protein of Chikungunya virus and has been tested for use in ELISA, Immunocytochemistry, Neutralizing asssay, and Western Blotting. The GC3 values ranged from 54.9% to 57.2%, with a mean of 55.86% and a standard deviation (SD) 0.40 compared with that of AU3, whose values ranged from 42.8% to 45.1%, with a mean of 44.14% and an SD of 0.41.

A complex correlation was observed among different nucleotide constraints (Table 3). Panel A, shows evidence of budding and the presence of an electron-dense mature particle (white arrow). In the case of GC3%, positive correlation was noted with C% (r = 0.498, P<0.01) and GC% (r = 0.852, P<0.01), and negative correlation with U% (r = −0.480, P<0.01); the correlation with G% was non-significant. The codons AUG and UGG are the only codons for Met and Trp, respectively, and the termination codons UAA, UAG and UGA do not encode any amino acids. The whole genomes of CHIKV … Our results revealed at least two introductions of DENV, in 2011 and late 2013, that initially originated from Venezuela and/or Colombia. Summary of the CHIKV replication cycle. For this purpose, we computed the GRAVY and aromaticity (ARO) values for each CHIKV isolate (Table S1) and a linear regression analysis was performed between GRAVY, ARO and the f′1, f′2, ENC, GC and GC3 values. The open triangles preceding the poly(A) tail indicate the 19-nt that is a highly conserved sequence element (CSE), among, Representative experiment of analysis of cells sensitivity to CHIKV. The book gives a comprehensive overview on the knowledge of virus infection relevant for humans and animals. Health Hazards. In case of the two transmission vectors, 10 out of 18 preferred codons were common among both mosquito species and CHIKV. Like other RNA viruses with high mutation rates, CHIKV produces populations of genetically diverse genomes within a host. Found insideThis book investigates how this facilitates the design and development of potent antiviral agents used against life-threatening viruses. Finally the GC and GC12 were also compared with GC3 and a highly significant positive correlations (r = 0.28, P<0.01; GC12 versus GC3) (r = 0.85, P<0.01; GC versus GC3) was observed as shown in Figure 6A and 6B respectively. Zhang et al. It has been proposed that CpG deficiency in pathogens is associated with the immunostimulatory properties of unmethylated CpGs, which are recognized by the host’s innate immune system as a pathogen signature [28]. However, a clearer picture of overall nucleotide composition that could influence the codon usage preference in CHIKV genomes emerged from the analysis of the nucleotide composition of the third position of codons (A3, U3, G3, C3) and of GC1, GC1,2, GC3 and AU3 (Table 1). Use insect repellent (containing DEET, picaridin, IR3535, and oil of lemon eucalyptus and paramenthane-diol products) when travelling to countries with CHIKV. a The Illumina mapping data presented in the table were obtained in 2017 on samples that had been collected and found positive for chikungunya or dengue virus by real-time reverse transcription-PCR in 2016. b ‘R1 + R2’ indicates paired-end sequencing. Notify others working in the lab. Chikungunya Virus. aegypti (ID # 378) samples on Q-paper were run in 1-plex format whereas chikungunya infected mosquito (ID # 401) was run in 3-plex format where all primers for Zika, chikungunya and dengue-1 were present in the RT-LAMP mixture. https://doi.org/10.1371/journal.pone.0090905.t006.

However, the spread of CHIKV in Asia and urban endemics are associated with a dengue-like “human-mosquito-human” direct transmission cycle, where A. aegypti and A. albopuctus serve as primary transmission vectors and humans serve as hosts [7]–[9]. 2015;3(2):e00164–15. A general mutational pressure, which affects the whole genome, would certainly account for the majority of the codon usage among certain RNA viruses [21]. The molecular architecture of the plasma membrane-associated replication complex from the Chikungunya virus is unknown. CHIKUNGUNYA VIRUS• Two changes to the structure of E1 Makes the virus more likely to enter mosquito cells and replicate after the insect has fed on the blood of an infected person A subgenomic positive-strand mRNA referred to as 26S RNA, is transcribed from a negative-stranded-RNA intermediate and serves as the mRNA for the synthesis of the viral structural proteins. All work involving infectious or potentially infectious material. Panel D, illustrated the massive production of particles from BHK-21 cells. https://doi.org/10.1371/journal.pone.0090905.g002. Because it is transmitted by arthropods, namely mosquitoes, it can also be referred to as an arbovirus(arthropod-borne virus). Chikungunya virus (CHIKV), is a member of the genus Alphavirus, and family Togaviridae. Spherical enveloped virion that measures 60 to 70 nm in diameter and contains a single-stranded, positive-sense RNA genome. State Key Laboratory of Pathogen and Biosecurity, Beijing Institute of Microbiology and Epidemiology, Beijing, People’s Republic of China. These findings suggested that despite being an RNA virus with a high mutation rate in its lifecycle, CHIKV has evolved to form a relatively stable genetic composition at some specific levels of synonymous codon usage. Careers. The genome of alphaviruses is an ∼12-kb positive-sensed single-stranded RNA molecule encoding four nonstructural proteins (nsP1–4), which are required for virus replication, and five structural proteins (capsid protein C, glycoproteins E1, E2, E3, and 6K) . Chikungunya virus (CHIKV), a member of the genus alphavirus of the family Togaviridae, is a small (60–70 nm), enveloped, single-strand positive-sense RNA virus.

First described in … This included UUC (Phe), CUG (Leu), AUC (Ile), GUG (Val), UAC (Tyr), AGA (Arg), UGC (Cys), CAC (His), CAG (Gln), AAC (Asn), AAG (Lys) and GAC (Asp). Schematic representation of the non-structural protein nsP2, showing the location of the consensus sequences for the helicase and the proteinase, respectively. Therefore, these five codons are expected not to exhibit any usage bias and were therefore excluded from the analysis. 3. Viruses 2019; 11: 1078. Chikungunya virus (CHIKV) is a significant human pathogen that causes debilitating and long-lasting arthritis. The outbreak has since spread to 38 regions in the Americas. Therefore, we first analyzed the nucleotide composition of coding sequences from CHIKV genomes. In detail, the preferred codons for 12 out of 18 amino acids were common between CHIKV and H. sapiens. The junction region (J) is also non-coding. https://doi.org/10.1371/journal.pone.0090905.s001. For more information about PLOS Subject Areas, click Highly expressed genes exhibit a strong bias for particular codons in many bacteria and small eukaryotes. The alphavirus genome is a single-stranded RNA genome of ~12 kb in size of positive polarity. The RSCU index was calculated as follows:where gij is the observed number of the ith codon for the jth amino acid which has ni kinds of synonymous codons. The chikungunya (CHIKV) viral infection is a global health burden characterized by the neurologic complications with CHIKV infection. Found insideThis book tried to update the significant epidemiological and clinical research in many aspects with a multinational perspective. Bookshelf f′2 axis showed significantly positive correlations with C3 (r = 0.69, P<0.01), GC3% (r = 0.74, P<0.01; Figure 7B), GC% (r = 0.64, P<0.01), A% (r = 0.17, P<0.05) and G% (r = 0.39, P<0.01) whereas, negative correlations with U3% (r = −0.66, P<0.01), and U% (r = −0.34, P<0.01) (Table 4). The following compositional properties were calculated for the CHIKV genomes; (i) the overall frequency of occurrence of the nucleotides (A %, C %, U/T %, and G %); (ii) the frequency of each nucleotide at the third site of the synonymous codons (A3%, C3%, U3% and G3%); (iii) the frequencies of occurrence of nucleotides G+C at the first (GC1), second (GC2), and third synonymous codon positions (GC3); (iv) the mean frequencies of nucleotide G+C at the first and the second position (GC1,2); and (v) the overall GC and AU content. It has now resulted in 2 cases of locally-transmitted Chikungunya virus in Florida in July of 2014. No specific treatment available. Unable to load your collection due to an error, Unable to load your delegates due to an error. Wash area with soap and water for 15 minutes. Chikungunya virus is a ribonucleic acid (RNA) virus transmitted by a mosquito bite. Yes We performed phylogeographic analyses of dengue (DENV) and chikungunya (CHIKV) virus genomes sampled from a surveillance site in Ecuador in 2014–2015, along with genomes from the surrounding countries. CHIKUNGUNYA VIRUS • Enveloped virions spherical, 60 to 70 nm in diameter positive-sense, single-stranded RNA genome, ca. Host Range: Humans, non-human primates, rodents, and birds. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. RSCU values represent the ratio between the observed usage frequency of one codon in a gene sample and the expected usage frequency in the synonymous codon family given that all codons for the particular amino acid are used equally. Contributed reagents/materials/analysis tools: AMB IN YT. Flush eyes, mouth or nose for 15 minutes at eyewash station. The sequence used for numbering is CHIKV sequence (Khan et al., 2002). Chikungunya fever is a mosquito-borne viral disease caused by the chikungunya virus (CHIKV). Other symptoms may include headache, muscle pain, joint swelling, or rash. Arboviruses (or arthropod-borne viruses), represent a threat for the new century. It is responsible for an acute infection of abrupt onset, characterized by high fever, arthralgia, myalgia, headache, and rash [ 4 , 5 ]. The similarity index was found to be highest for A. albopictus vs. CHIKV group followed by P. troglodytes vs. CHIKV, A. aegypti vs. CHIKV and lowest in the case of H. sapiens vs. CHIKV (Figure 2), indicating that the effect of A. albopictus and P. troglodytes on the formation of the overall codon usage patterns of CHIKV is relatively higher than that of the A. aegypti and H. sapiens. By contrast, P. troglodytes had its strongest and equal effect on ECSA and Asian genotypes, followed by WA genotype (Figure 2). Allow aerosols to settle. Severson DW, Behura SK. Over-representation of CpA and UpG in different organisms has been observed and is regarded as a consequence of the under-representation of CpG dinucleotides. (2002); the other sequences are from Strauss and Strauss (1994). The Phosphatidylserine Receptor TIM-1 Enhances Authentic Chikungunya Virus Cell Entry. From the 50 samples, we were able to generate 33 complete or near-complete genome sequences (17 CHIKV and 16 DENV genomes) ( Table ). 2. The chikungunya virus genome encodes for two polyproteins, which are the non structural polyprotein consisting of four proteins the nsP1, nsP2, nsP3, nsP4. The virion is 70 nm in diameter and it is composed of repeating units of the E1 and E2 transmembrane glycoproteins (240 heterodimers of E2/E1 arranged as trimeric spikes on its surface), the capsid (C), a host-derived lipid bilayer, and a single molecule of genome RNA. The synonymous codons with RSCU values >1.0 have positive codon usage bias and were defined as abundant codons, while those with RSCU values <1.0 have negative codon usage bias and were defined as less-abundant codons. The stronger effect of P. troglodytes than H. sapiens could also be attributed to the maintenance of CHIKV in a yellow fever-like zoonotic sylvatic cycle and its dependence upon non-human primates as reservoir hosts [7], [9]. The systematic review was undertaken to provide data on incidence, the seroprevalence of anti-Chikungunya virus (CHIKV) IgM and IgG antibodies, mortality, the genotypes of circulating CHIKV and travel-related cases of chikungunya in the country. The RNA is contained within a protein shell, or capsid, which in turn is covered by a phospholipid layer, or envelope. Therefore, to determine the trends in codon usage variation among different CHIKV genomes, we performed COA on the RSCU values, which were examined as a single dataset based on the RSCU value of each coding region (Figure 3). Similarly, preferred codons for 10 out of 18 amino acids were common between CHIKV and P. troglodytes. Centre of Excellence in Molecular Biology (CEMB), University of the Punjab, Lahore, Pakistan, Affiliation The odds ratio was calculated using the following formula:where fx denotes the frequency of the nucleotide X, fy denotes the frequency of the nucleotide Y, fy fx the expected frequency of the dinucleotide XY and fxy the frequency of the dinucleotide XY, etc,. (2010) Genome- characterization of 2006–2008 isolates of Chikungunya virus from Kerala, South scale phylogenetic analyses of chikungunya virus reveal independent emergences India, by whole genome sequence analysis. Excess Complete genome sequence of a chikungunya virus imported from Bali to mortality profile during the Asian genotype chikungunya epidemic in the Germany. Interestingly, GpC dinucleotides also deviated from the normal range and were instead slightly over-represented (mean ± SD = 1.001±0.007) (Table 5). FOIA This edition is an updated, revised and greatly expanded guide to the classes of organisms that infect humans. GENOME ANNOUNCEMENT. f′1 showed a significantly positive correlation with U3% (r = 0.31, P<0.01), G3% (r = 0.58, P<0.01), U% (r = 0.25, P<0.01) and C% (r = 0.51, P<0.01); however, it showed significantly negative correlations with A% (r = −0.54, P<0.01), G% (r = −0.29, P<0.01), A3% (r = −0.50, P<0.01), C3 (r = −0.35, P<0.01), GC3 (r = −0.24, P<0.01; Figure 7A) and GC% (r = −0.21, P<0.01). Is the Subject Area "Chikungunya virus" applicable to this article? DR.T.V.RAO MD 10 11. Zika-infected Ae. D(A,B) represents the potential effect of the overall codon usage of the host on that of CHIKV, and its value ranges from zero to 1.0 [36]. Chikungunya virus is transmitted by an Aedes aegypti or Aedes albopictus mosquito. Currently, there is no approved vaccine or specific therapeutic. CHIKUNGUNYA Dr.T.V.Rao MD . This redundancy of the genetic code, in which most of the amino acids can be translated by more than one codon, represents a key step in modulating the efficiency and accuracy of protein production, while maintaining the same amino acid sequence of the protein. It was first isolated in 1953 in Tanzania and is an RNA virus with a positive-sense single-stranded genome of about 11.6kb. Chikungunya virus (CHIKV) is the causative agent of an arthropod (mosquito) transmitted disease which is characterised by a high fever, rash, joint pain, and arthritis which was reported in 1952 in Tanzania but has spread since to Europe, Asia, Oceania and more recently … Chen R, Puri V, Fedorova N, Lin D, Hari KL, Jain R, et al. 2015;3(2):e00164–15. In general, there is an inverse relationship between ENC and gene expression; i.e., a lower ENC value indicates a higher codon usage preference and higher gene expression and vice versa [30]. The conserved ribosome-binding sequence (amino acids 98 to 112) is indicated. One possible explanation is that methylated cytosines are prone to mutate into thymines through spontaneous deamination, resulting in the dinucleotide TpG and the subsequent presence of a CpA on the opposite strand after DNA replication [47]. Furthermore, all common preferred codons between CHIKV and H. sapiens were G/C- ended (C-ended: 7; G-ended: 4), with exception of an A-ended preferred codon for amino acid Arg. CHIKV is a positive-sense single-stranded RNA (+ssRNA) virus and has emerged as a major global human pathogen in the twenty-first century as its geographic distribution continues to expand. Here, we calculated the CAI values of coding sequences from CHIKV genomes. Contributed articles. Among the 16 dinucleotides, 11 significantly (positive and negative) correlated with the first axis and 16 significantly (positive and negative) correlated with the second axis (Table 5). The different non-structural proteins (nsP1–nsP4) and structural proteins (C, Capsid; E1, E2, E3, envelope; 6K) are generated after proteolytic cleavage of polyprotein precursors. Recognition of umethylated CpGs by Toll like receptor 9 (TLR9), a type of intracellular pattern recognition receptor (PRR), leads to activation of several immune response pathways [44]. , with a positive-sense single-stranded genome of ~12 kilobases over-representation of CpA and in!
