Diversity, Abundance and Host Blood Meal Analysis of Culicoides Latreille (Diptera: Ceratopogonidae) from Cattle Pens in Different Land Use Types from Thailand. INSECTS 2023; 14:574. [PMID: 37504581 PMCID: PMC10380999 DOI: 10.3390/insects14070574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 06/20/2023] [Accepted: 06/21/2023] [Indexed: 07/29/2023]
Abstract
Biting midges of the genus Culicoides Latreille are significant pests and vectors that transmit pathogens to humans and other animals. Cattle are among the important livestock that can potentially be severely affected by Culicoides. In this study, we examined the species diversity, abundance, and host blood meal identification of biting midges in cattle pens located in three different land use types: villages, agricultural areas, and the forest edge. A total of 12,916 biting midges were collected, and most of these were from cattle pens located in villages (34%) and agricultural land (52%). Morphological identification revealed 29 Culicoides species. The most common species were C. oxystoma, C. mahasarakhamense, C. peregrinus, and C. shortti; taken together, these species represented >80% of all specimens collected. Despite midges being less numerous (14% of the total collection), cattle pens located near the forest showed greater diversity (23) than those from villages and agricultural areas. More diverse immature habitats and host blood sources from wildlife in nearby forests possibly explain the greater diversity in the cattle pens near the forest edge. Host blood meal analysis revealed that most (65%) biting midges had fed on buffalo despite the fact that this animal was much less numerous than cows or chickens. Relatively larger size and black-colored skin could be factors that make buffalo more attractive to biting midges than other host species. In this study, we also provided 67 DNA barcoding sequences of 13 species, three of which (C. flaviscutatus, C. geminus, and C. suzukii) were first reported from Thai specimens. DNA barcode analysis indicated cryptic diversity within C. hegneri and C. flavescens in Thailand, and thus, further investigation is required to resolve their species status.

[PMID: 37061640 DOI: 10.1007/s00203-023-03527-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 03/28/2023] [Accepted: 03/29/2023] [Indexed: 04/17/2023]
Abstract
Bovine ephemeral fever virus (BEFV) is an economically important arthropod-borne virus of cattle and water buffaloes which is enzootic in Africa, Australia, and Asia. We characterized the entire length of BEFV BA/RZ/IR strain genome isolated in Iran and compared to the all BEFV full genomes available in the GenBank. The BEFV genomes were phylogenetically classified as 4 lineages including the Middle Eastern, East Asian, Australian, and South African lineages. The Iranian BA/RZ/IR strain, which displayed maximum sequence identity (96.72%) to the Chinese JT02L strain was clustered as a separate branch in the East Asian lineage of the virus. Using Shannon entropy analysis, amino acid variations were detected in the all proteins encoded by BEFV genomes. Particularly, the polymerase L and the accessory proteins Gns, α2 and β exhibited the highest amino acid variations suggesting their significance in the viral replication efficiency. Our bioinformatics analyses also predict the occurrence of recombination event within the East Asian lineage of BEFV genomes. Our data show that the Chinese Henan 1 may be a hybrid strain constructed of the Chinese JT02L and Iranian BA/RZ/IR BEFV strains as the major and minor parents, respectively. These computational analyses suggest that the homologous recombination may be an evolutionary mechanism for BEFV as a member of the Rhabdoviridae family.

Abstract
Introduction Bovine ephemeral fever virus (BEFV), belonging to the genus Ephemerovirus under the family Rhabdoviridae, is the etiological cause for the bovine ephemeral fever (BEF) in cattle and water buffalo. Methods In this study, we report recent BEF outbreaks in Southwest China and sequence the complete genome sequence of one BEFV isolate BEFV/CQ1/2022. Results and Discussion Comparative genomic analyses between BEFV/CQ1/2022 and isolates available in GenBank revealed remarkable inter-isolate divergence. Meanwhile, the sequence divergence was related to the evolutionary relationships and geographical distribution of the isolates. Phylogenetic analysis indicated that the global BEFV isolates can be divided into 4 distinct lineages. The East Asia lineage was the most diverse and could be subdivided into 4 sublineages. Notably, BEFV/CQ1/2022 and other 10 recent isolates from Mainland China were found to be clustered in sublineage 2. Additionally, recombination analysis provided evidence of BEFV recombination among East Asian isolates for the first time. Taken together, a novel sublineage of the East Asian BEFV emerged in Southwest China, and large divergence and potential recombination among BEFV strains were investigated in this study, which may improve understanding of BEFV epidemiology and evolution.

Abstract
Simple Summary Lumpy skin disease (LSD) is an economically important disease of cattle caused by LSD virus (LSDV), a member of poxviruses. It had never been found in Thailand before March 2021, but has since spread broadly to various provinces. Regional veterinarians have collected samples from the LSD cattle and submitted them for diagnosis as a part of disease surveillance during the outbreaks. Our study aimed to monitor the distribution of the outbreaks by recording the LSD cases based on clinical signs and laboratory tests up to June 2022, and characterise the causative agent virologically and genetically. Outbreak maps were created to illustrate the rapid temporal distribution of the LSD index cases in each province of Thailand. We detected two distant origins of the outbreaks. LSDV DNA was confirmed in blood, milk, and skin samples collected from sick animals by real-time PCR. LSDV was proven to be the causative virus based on serological, virological, and pathological diagnoses. By genetic analysis, the Thai LSDV is a recombinant virus derived from a vaccine strain previously appearing in China and Vietnam. Its genetic material is a mosaic hybrid genome containing the vaccine virus DNA as the backbone interspersed with DNA fragments of a field strain. Abstract The emergence of the lumpy skin disease virus (LSDV) was first detected in north-eastern Thailand in March 2021. Since then, the abrupt increase of LSD cases was observed throughout the country as outbreaks have spread rapidly to 64 out of a total of 77 provinces within four months. Blood, milk, and nodular skin samples collected from affected animals have been diagnosed by real-time PCR targeting the p32 gene. LSDV was isolated by primary lamb testis (PLT) cells, followed by Madin-Darby bovine kidney (MDBK) cells, and confirmed by immunoperoxidase monolayer assay (IPMA). Histopathology and immunohistochemistry (IHC) of a skin lesion showed inclusion bodies in keratinocytes and skin epithelial cells. Phylogenetic analyses of RPO30 and GPCR genes, and the whole genome revealed that Thai viruses were closely related to the vaccine-derived recombinant LSDV strains found previously in China and Vietnam. Recombination analysis confirmed that the Thai LSDV possesses a mosaic hybrid genome containing the vaccine virus DNA as the backbone and a field strain DNA as the minor donor. This is an inclusive report on the disease distributions, complete diagnoses, and genetic characterisation of LSDV during the first wave of LSD outbreaks in Thailand.

Abstract
Bovine ephemeral fever virus (BEFV) infection occurs seasonally in many tropical and subtropical regions of Africa, Asia (including the Middle East), and Australia while it is exotic in Europe. In this study, the epidemiology of BEFV infection in Turkey that bridges southeastern Europe and Asia, geographically, was investigated according to the comparison of the nucleotide sequences of the virus caused the last epidemic in 2020 with those of the strains previously detected in Turkey as well as BEFV strains from other countries. In the phylogenetic analysis, based on an alignment of full-length G gene sequences, BEFVs from epidemic-2020 were located in Middle Eastern lineage and appear to represent most closely related BEFVs from India-2018 and 2019. The findings will contribute to a better understanding of BEFV epidemiology in Turkey.

Abstract
Bovine ephemeral fever (BEF), caused by the bovine ephemeral fever virus (BEFV), is associated with an acute febrile infection in cattle and widespread in tropical and subtropical areas, leading to great economic losses to cattle and milk industry. However, no efficacious BEF vaccine is currently available in China. Herein, we generated a recombinant rabies virus (RABV) expressing BEFV glycoprotein (LBNSE-BG), utilizing a reverse genetics system based on the recombinant rabies virus strain LBNSE. It was found that mice immunized with LBNSE-BG produced robust neutralizing antibodies against both BEFV and RABV, and developed complete protection from lethal RABV challenge. Further studies showed that LBNSE-BG activated more dendritic cells (DCs), B cells and T cells in immunized mice than the parent virus LBNSE. Collectively, these findings demonstrate that the recombinant LBNSE-BG described here has the potential to be developed as a cost-effective and efficacious bivalent vaccine for cattle use in endemic areas of BEF and rabies.

Abstract
Epizootic congenital abnormalities caused by Akabane, Aino, and Chuzan viruses have damaged the reproduction of domestic ruminants in East Asia for many years. In the past, large outbreaks of febrile illness related to bovine ephemeral fever and Ibaraki viruses severely affected the cattle industry in that region. In recent years, vaccines against these viruses have reduced the occurrence of diseases, although the viruses are still circulating and have occasionally caused sporadic and small-scaled epidemics. Over a long-term monitoring period, many arboviruses other than the above-mentioned viruses have been isolated from cattle and Culicoides biting midges in Japan. Several novel arboviruses that may infect ruminants (e.g., mosquito- and tick-borne arboviruses) were recently reported in mainland China based on extensive surveillance. It is noteworthy that some are suspected of being associated with cattle diseases. Malformed calves exposed to an intrauterine infection with orthobunyaviruses (e.g., Peaton and Shamonda viruses) have been observed. Epizootic hemorrhagic disease virus serotype 6 caused a sudden outbreak of hemorrhagic disease in cattle in Japan. Unfortunately, the pathogenicity of many other viruses in ruminants has been uncertain, although these viruses potentially affect livestock production. As global transportation grows, the risk of an accidental incursion of arboviruses is likely to increase in previously non-endemic areas. Global warming will also certainly affect the distribution and active period of vectors, and thus the range of virus spreads will expand to higher-latitude regions. To prevent anticipated damages to the livestock industry, the monitoring system for arboviral circulation and incursion should be strengthened; moreover, the sharing of information and preventive strategies will be essential in East Asia.

Abstract
Bovine ephemeral fever virus (BEFV) is an economically important arbovirus affecting cattle and water buffalo. Currently, isolates can be separated into three phylogenetic groups, differentiated by the place of isolation, namely, East Asia, Australia, and the Middle East. BEFV surface glycoprotein (G) genes from 14 South African field strains collected between 1968 and 1999 were sequenced and compared to 154 published sequences. The BEFV isolates from South Africa were found to be phylogenetically distinct from those from other parts of the world.

Abstract
Bovine ephemeral fever virus (BEFV) can cause bovine ephemeral fever and is an economically important arbovirus of cattle. To expand the knowledge of the molecular epidemiology of BEFV in southern China, the complete surface glycoprotein G gene of BEFV was sequenced from samples collected in five restricted outbreaks from 2013 to 2017, namely 2013ZH, 2014HM, 2015GX, 11082-2016, and qy2017. It was noted that both 2014HM and 11082-2016 were detected in cattle regularly vaccinated with inactivated vaccine. Phylogenetic analysis demonstrated that all five strains grouped into cluster I. However, qy2017 was closer to the BEFV strains identified in Thailand, Japan, and Taiwan after 2000, while 2013ZH, 2014HM, 2015GX, and 11082-2016 were closer to the Chinese strains in 2011 and the Turkey strains in 2012. The analysis of antigenic sites indicated that several amino acid changes occurred between the five strains and the vaccine strain. Importantly, one novel amino acid mutation site was observed in the putative N-linked glycosylation sites of 2013ZH, 2014HM, 2015GX, and 11082-2016. Our study indicated novel genetic characteristics of the newly emerging BEFV strains in southern China and the necessity of updating the component of commercially available inactivated BEFV vaccines in China.

Abstract
Bovine ephemeral fever is an arthropod-borne viral disease affecting mainly domestic cattle and water buffalo. The etiological agent of this disease is bovine ephemeral fever virus, a member of the genus Ephemerovirus within the family Rhabdoviridae. Bovine ephemeral fever causes economic losses by a sudden drop in milk production in dairy cattle and loss of condition in beef cattle. Although mortality resulting from this disease is usually lower than 1%, it can reach 20% or even higher. Bovine ephemeral fever is distributed across many countries in Asia, Australia, the Middle East, and Africa. Prevention and control of the disease mainly relies on regular vaccination. The impact of bovine ephemeral fever on the cattle industry may be underestimated, and the introduction of bovine ephemeral fever into European countries is possible, similar to the spread of bluetongue virus and Schmallenberg virus. Research on bovine ephemeral fever remains limited and priority of investigation should be given to defining the biological vectors of this disease and identifying virulence determinants.

Abstract
Bovine ephemeral fever virus (BEFV) causes an acute febrile disease in cattle and water buffalo. The disease has an impact on dairy and beef production in tropical and subtropical countries. Vaccination is used for disease prevention and control. In this study, we developed a recombinant lentivirus to produce mammalian stable cells expressing histidine-tagged BEFV G protein with a deleted transmembrane domain (GΔTM) as a secretory protein. In addition, guinea pigs were immunised with the purified GΔTM protein and booster immunised at a 3-week interval. The mammalian stable cells were able to continuously produce GΔTM protein for a minimum of 25 passages. All of the mammalian stable cells expressing GΔTM protein could react specifically with a BEFV convalescent bovine serum. Serum samples from the immunised guinea pigs could react strongly and specifically with the purified GΔTM protein. Moreover, post-immunised guinea pig sera contained antibodies that could neutralise BEFV. These results indicate that the G protein without a transmembrane domain can be used as a subunit vaccine for the prevention and control of BEFV. The availability of the mammalian stable cells, which constitutively express GΔTM protein, could facilitate the potential use of the secretory protein for BEFV diagnosis and vaccine development.
