[Ti] Título: Isolation, complete genome sequencing, and phylogenetic analysis of the first Chuzan virus in China. [So] Source: Virus Genes;52(1):138-41, 2016 Feb. [Is] ISSN: 1572-994X [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: A Chuzan virus (CHUV), defined as GX871 here, was isolated from blood from a sentinel cattle firstly in China, and its full-length genome was sequenced in this study. The GX871 genome included 10 segments and 18914 bp, one base fewer than the CHUV prototype strain K-47 due to a one-base deletion in the 5' non-coding region of segment 8. A frameshift mutation was detected in a short coding region (1010-1026 nt) corresponding to the VP1 protein; this frameshift resulted in a five-amino acid mutation from 336CVLSY340 to 336YGAKL340. In addition, there were a one-base deletion at 1713 nt and a one-base insertion at 1682 nt in the 3' non-coding region of segment 5. Based on phylogenetic analysis of the deduced VP2 amino acid sequences, Palyam serogroup viruses were classified into three groups. The Chinese CHUV isolate GX871 was categorized into the same group as CHUV prototype strain K-47. The phylogenetic tree was divided into three clusters according to the geographical distribution of the partial nucleotide sequences of VP7, and this arrangement might define the geographical gene pool of CHUV.

[Ti] Título: Complete genome sequence of a Chuzan virus strain isolated for the first time in mainland China. [So] Source: Arch Virol;161(4):1073-7, 2016 Apr. [Is] ISSN: 1432-8798 [Cp] País de publicação: Austria [La] Idioma: eng [Ab] Resumo: Chuzan virus (CHUV) belongs to the Palyam serogroup, causes bovine congenital disease, and is prevalent in Asia. To date, only one full Palyam virus (PALV) genome sequence, that of Japanese CHUV strain K47, has been reported. Sequence analysis indicates that PALV strains isolated from different geographical regions show significant diversity, which is mainly shaped by geographically independent evolution and genetic reassortment. Our understanding of the genetic characteristics of PALV is hampered by a very limited genomic sequence database. In this study, we report the complete genome sequence of CHUV strain SZ187, which was isolated for the first time in 2012 in mainland China. Sequence alignment and phylogenetic analysis demonstrate that SZ187 is closely related to other CHUV strains isolated in Taiwan and Japan, indicating that they may share a common ancestor. This new full-length CHUV genome sequence could help in the design of broader assays for epidemiological studies and facilitate the identification of new CHUV isolates in the future.

[PMID]: 24313924 [Au] Autor: Hechinger S; Wernike K; Beer M [Ti] Título: Evaluating the protective efficacy of a trivalent vaccine containing Akabane virus, Aino virus and Chuzan virus against Schmallenberg virus infection. [So] Source: Vet Res;44:114, 2013 Dec 05. [Is] ISSN: 1297-9716 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: Schmallenberg virus (SBV), an arthropod borne pathogen, spread rapidly throughout the majority of Europe since 2011. It can cause a febrile disease, milk drop, diarrhea, and fetal malformation in ruminants. SBV, a member of the Simbu serogroup within the genus Orthobunyavirus, is closely related to Akabane virus (AKAV) and Aino virus (AINOV) among others. In the present study, 4 Holstein-Friesian calves were immunized twice four weeks apart with a multivalent, inactivated vaccine against AKAV and AINOV. Another 4 calves were kept as unvaccinated controls. All animals were clinically, serologically and virologically examined before and after challenge infection with SBV. AKAV- and AINOV-specific neutralizing antibodies were detected one week before challenge infection, while SBV-specific antibodies were detectable only thereafter. SBV genome was detected in all vaccinated animals and 3 out of 4 controls in serum samples taken after challenge infection. In conclusion, the investigated vaccine was not able to prevent an SBV-infection. Thus, vaccines for other related Simbu serogroup viruses can not substitute SBV-specific vaccines as an instrument for disease control.

[Ti] Título: Development of inactivated trivalent vaccine for the teratogenic Aino, Akabane and Chuzan viruses. [So] Source: Biologicals;39(3):152-7, 2011 May. [Is] ISSN: 1095-8320 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: Aino, Akabane and Chuzan viruses are arthropod-borne (arbo) viruses transmitted by blood-sucking insects like mosquitoes and Culicoides biting midges. These arbovirus infections are mainly associated with abortion, stillbirth and congenital defects in pregnant cattle, sheep and goats, which induces a considerable economic loss in livestock industry. The viruses seem to be widely distributed in Southeast Asia and Australia. As a control strategy, an inactivated trivalent vaccine against Aino, Akabane and Chuzan virus was developed by using binary ethylenimine or formalin as an inactivating agent. The newly developed trivalent vaccine is evaluated for its safety and immunogenicity in animals such as mice, guinea pigs and cattle. The immune responses were significantly detected within 2-weeks after second vaccination without any side effects. Since the field application of experimental vaccine also revealed increased antibodies in inoculated cattle, we demonstrated that these trivalent vaccines could be used as a vaccine to control the arboviral infections in ruminants.

[So] Source: J Vet Med Sci;70(9):977-9, 2008 Sep. [Is] ISSN: 0916-7250 [Cp] País de publicação: Japan [La] Idioma: eng [Ab] Resumo: A total of 804 goat sera were collected from 144 goat farms in five regions of South Korea during a period between 2005 and 2006 and screened for the antibodies of viral pathogens in ruminants. The individual seropositive rates for each virus were 13.7% (110/804) for bovine herpesvirus-1 (BHV-1), 9.5% (76/804) for bovine parainfluenza type-3 virus (PI-3V), 5.5% (44/804) for Akabane virus (AKAV), 13.3% (107/804) for Aino virus (AINV), 2.0% (16/804) for Chuzan virus (CHUV) and 1.0% (8/804) for bovine coronavirus (BCoV). Compared with other areas, Chungcheong Province showed higher seropositive rates of 13.6% for PI-3V, 22.3% for AKAV and 28.2% for AINV. The results indicate that among the six viral diseases, BHV-1 infection is quite prevalent, while BCoV infection is less prevalent on domestic goat farms in Gyeongsang and Jeonla Provinces.

[So] Source: J Clin Microbiol;42(10):4610-4, 2004 Oct. [Is] ISSN: 0095-1137 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: The Japanese isolates of Palyam serogroup viruses isolated from 1985 to 2001 were investigated for the genome sequence of segments 2 and 7 and were phylogenetically analyzed in comparison with Australian and African isolates of the same serogroup. The nucleotide sequences of segment 7 were highly conserved within Japanese isolates (95.1 to 100%) and between Japanese and Taiwanese isolates (96.0 to 100%), whereas the identities between Japanese and Taiwanese isolates and Australian and African isolates were fairly conserved (84.2 to 92.0%). Phylogenetic analysis based on segment 7 revealed three clusters according to geographical origin. As a result of the nucleotide sequence analysis of segment 2, which encodes a serotype-specific antigen, Japanese isolates were classified into two groups by genome length and nucleotide identities. Four of the nine Japanese isolates were categorized into the same group as prototype strain K-47 of the Chuzan virus, and the remaining isolates were categorized into the same group as the D'Aguilar virus and Nyabira virus. Phylogenetic analysis based on segment 2 revealed two clusters, the cluster containing Chuzan virus and the cluster containing the D'Aguilar and Nyabira viruses. To examine the antigenic relationship among viruses categorized in different clusters, we conducted a cross-neutralization test. KSB-29/E/01, isolated in 2001 in Japan, was neutralized by antiserum not only to strain B8112 of D'Aguilar virus but also to Chuzan virus. These results indicated that genetically and antigenically unique characteristics of KSB-29/E/01 were attributed to genetic reassortment of segment 2 between Chuzan virus and D'Aguilar virus.

[So] Source: Vet Microbiol;83(4):333-41, 2001 Dec 04. [Is] ISSN: 0378-1135 [Cp] País de publicação: Netherlands [La] Idioma: eng [Ab] Resumo: The Palyam serogroup-specific antigen, VP7, of Chuzan virus strain K-47 was expressed in insect cells by a recombinant baculovirus. The expressed protein appeared as a single band of 38kDa corresponding to the predicted molecular mass of Chuzan virus VP7 by SDS-polyacrylamide gel electrophoresis (SDS-PAGE). In immunoprecipitation analysis, the recombinant VP7 was not only recognized by all polyclonal antibodies against the Palyam serogroup viruses (PALV) tested in this study, but also by antisera to bluetongue virus (BTV) serotype 1, epizootic haemorrhagic disease virus (EHDV) serotypes 1 and 2. However, in Western immunoblot assay, no positive signals were observed between this protein and these antisera, even in the homologous reaction using antiserum to Chuzan virus. These findings demonstrate that the common antigenic determinants on the VP7 proteins of Chuzan virus and the other PALV serotypes are mainly conformational and that the proteins share some epitopes with those of BTV and EHDV beyond the serogroup. No cross-reactivities were detected between Chuzan virus VP7 and antisera to BTV and EHDV in agar gel immunodiffusion (AGID) and indirect ELISA tests, indicating that the recombinant VP7 is useful as a diagnostic reagent for serological tests of congenital abnormalities of cattle caused by PALV.
