In vitro assembly of alphavirus cores by using nucleocapsid protein expressed in Escherichia coli. (1/97)

The production of the alphavirus virion is a multistep event requiring the assembly of the nucleocapsid core in the cytoplasm and the maturation of the glycoproteins in the endoplasmic reticulum and the Golgi apparatus. These components associate during the budding process to produce the mature virion. The nucleocapsid proteins of Sindbis virus and Ross River virus have been produced in a T7-based Escherichia coli expression system and purified. In the presence of single-stranded but not double-stranded nucleic acid, the proteins oligomerize in vitro into core-like particles which resemble the native viral nucleocapsid cores. Despite their similarities, Sindbis virus and Ross River virus capsid proteins do not form mixed core-like particles. Truncated forms of the Sindbis capsid protein were used to establish amino acid requirements for assembly. A capsid protein starting at residue 19 [CP(19-264)] was fully competent for in vitro assembly, whereas proteins with further N-terminal truncations could not support assembly. However, a capsid protein starting at residue 32 or 81 was able to incorporate into particles in the presence of CP(19-264) or could inhibit assembly if its molar ratio relative to CP(19-264) was greater than 1:1. This system provides a basis for the molecular dissection of alphavirus core assembly.  (+info)

Macrophage-induced muscle pathology results in morbidity and mortality for Ross River virus-infected mice. (2/97)

Ross River virus (RRV) is an Australian alphavirus that is often responsible for chronic epidemic polyarthritis and myalgia in humans. Past studies have shown severe disruption of striated muscle fibers to be prominent in RRV pathology in mice; in the present study, macrophages were directly implicated as the primary mediators of muscle damage. General immunosuppressive therapies had only minor effects on mortality and morbidity in RRV-infected mice, with no inhibition of muscle damage. Treatment of mice with macrophage-toxic agents (e.g., silica) prior to RRV infection completely abrogated disease symptoms without significantly affecting titers of virus in organs. Further studies found that clinical signs of infection and muscle damage correlated with a massive influx of macrophages into hind leg muscle, whereas no such infiltrate or damage was observed for silica-treated mice. These observations are significant for the human disease context, as monocytic cells have been detected in the synovial effusions of persons with epidemic polyarthritis.  (+info)

Adaptive mutations in Sindbis virus E2 and Ross River virus E1 that allow efficient budding of chimeric viruses. (3/97)

Alphavirus glycoproteins E2 and E1 form a heterodimer that is required for virus assembly. We have studied adaptive mutations in E2 of Sindbis virus (SIN) and E1 of Ross River virus (RR) that allow these two glycoproteins to interact more efficiently in a chimeric virus that has SIN E2 but RR E1. These mutations include K129E, K131E, and V237F in SIN E2 and S310F and C433R in RR E1. Although RR E1 and SIN E2 will form a chimeric heterodimer, the chimeric virus is almost nonviable, producing about 10(-7) as much virus as SIN at 24 h and 10(-5) as much after 48 h. Chimeras containing one adaptive change produced 3 to 20 times more virus than did the parental chimera, whereas chimeras with two changes produced 10 to 100 times more virus and chimeras containing three mutations produced yields that were 180 to 250 times better. None of the mutations had significant effects upon the parental wild-type viruses, however. Passage of the triple variants eight or nine times resulted in variants that produced virus rapidly and were capable of producing >10(8) PFU/ml of culture fluid within 24 h. These further-adapted variants possessed one or two additional mutations, including E2-V116K, E2-S110N, or E1-T65S. The RR E1-C433R mutation was studied in more detail. This Cys is located in the putative transmembrane domain of E1 and was shown to be palmitoylated. Mutation to Arg-433 resulted in loss of palmitoylation of E1. The positively charged arginine residue within the putative transmembrane domain of E1 would be expected to alter the conformation of this domain. These results suggest that interactions within the transmembrane region are important for the assembly of the E1/E2 heterodimer, as are regions of the ectodomains possibly identified by the locations of adaptive mutations in these regions. Further, the finding that four or five changes in the chimera allow virus production that approaches the levels seen with the parental SIN and exceeds that of the parental RR illustrates that the structure and function of SIN and RR E1s have been conserved during the 50% divergence in sequence that has occurred.  (+info)

Detection of viral ribonucleic acid and histologic analysis of inflamed synovium in Ross River virus infection. (4/97)

OBJECTIVE: To document the histology of Ross River virus (RRV) arthritis and to examine inflamed synovium for viral RNA. METHODS: Biopsy tissue from the inflamed knees of 12 patients with RRV infection was studied using conventional and immunostaining techniques. Reverse transcriptase-polymerase chain reaction technology was used to probe for the presence of viral RNA in the synovial biopsy samples and in serum. RESULTS: Hyperplasia of the synovial lining layer, vascular proliferation, and mononuclear cell infiltration were the main histologic changes. RRV RNA was found in knee biopsy tissue that was obtained from 2 patients at 5 weeks after the onset of symptoms. CONCLUSION: RRV RNA was identified in inflamed synovium more than a month after symptoms began. Inflammation was apparent in the absence of detectable virus in the majority of patients.  (+info)

Specific ablation of antiviral gene expression in macrophages by antibody-dependent enhancement of Ross River virus infection. (5/97)

Ross River virus (RRV) is an indigenous Australian arthropod-borne alphavirus responsible for epidemic polyarthritis (EPA), myalgia, and lethargy in humans. Macrophages and monocytes have been associated with human RRV disease, and previous studies have shown that RRV is capable of infecting macrophages via both a natural virus receptor and by Fc receptor-mediated antibody-dependent enhancement (ADE). Similar to other viruses, such as human immunodeficiency virus and dengue virus, ADE infection results in dramatic RRV growth increases for in vitro macrophage cultures. This study demonstrates that RRV could resist lipopolysaccharide (LPS)-induced antiviral activity in macrophage cultures when infection was via the ADE pathway. Investigation of this infection pathway found that RRV was able to suppress the transcription and translation of key antiviral genes (tumor necrosis factor and inducible nitric oxide synthase) in LPS-stimulated macrophages by disrupting the transcription into mRNA of the genes coding for the associated transcription factors IRF-1 and NF-kappaB. The transcription of non-antiviral control genes was not perturbed by RRV-ADE infection, and de novo protein synthesis also was not significantly affected in RRV-ADE infected cells. The ADE pathway of infection allowed RRV to specifically target antiviral genes in macrophages, resulting in unrestricted virus replication. As ADE has been observed for several virus families and associated with disease and adverse vaccination outcomes, these findings may have broad relevance to viral disease formation and antiviral vaccination strategies.  (+info)

Characterization of epitopes for virus-neutralizing monoclonal antibodies to Ross River virus E2 using phage-displayed random peptide libraries. (6/97)

Ross River virus (RRV) is the predominant cause of epidemic polyarthritis in Australia, yet the antigenic determinants are not well defined. We aimed to characterize epitope(s) on RRV-E2 for a panel of monoclonal antibodies (MAbs) that recognize overlapping conformational epitopes on the E2 envelope protein of RRV and that neutralize virus infection of cells in vitro. Phage-displayed random peptide libraries were probed with the MAbs T1E7, NB3C4, and T10C9 using solution-phase and solid-phase biopanning methods. The peptides VSIFPPA and KTAISPT were selected 15 and 6 times, respectively, by all three of the MAbs using solution-phase biopanning. The peptide LRLPPAP was selected 8 times by NB3C4 using solid-phase biopanning; this peptide shares a trio of amino acids with the peptide VSIFPPA. Phage that expressed the peptides VSIFPPA and LRLPPAP were reactive with T1E7 and/or NB3C4, and phage that expressed the peptides VSIFPPA, LRLPPAP, and KTAISPT partially inhibited the reactivity of T1E7 with RRV. The selected peptides resemble regions of RRV-E2 adjacent to sites mutated in neutralization escape variants of RRV derived by culture in the presence of these MAbs (E2 210-219 and 238-245) and an additional region of E2 172-182. Together these sites represent a conformational epitope of E2 that is informative of cellular contact sites on RRV.  (+info)

Ross River virus glycoprotein-pseudotyped retroviruses and stable cell lines for their production. (7/97)

Pseudotyped retroviruses have important applications as vectors for gene transfer and gene therapy and as tools for the study of viral glycoprotein function. Recombinant Moloney murine leukemia virus (Mo-MuLV)-based retrovirus particles efficiently incorporate the glycoproteins of the alphavirus Ross River virus (RRV) and utilize them for entry into cells. Stable cell lines that produce the RRV glycoprotein-pseudotyped retroviruses for prolonged periods of time have been constructed. The pseudotyped viruses have a broadened host range, can be concentrated to high titer, and mediate stable transduction of genes into cells. The RRV glycoprotein-pseudotyped retroviruses and the cells that produce them have been employed to demonstrate that RRV glycoprotein-mediated viral entry occurs through endocytosis and that membrane fusion requires acidic pH. Alphavirus glycoprotein-pseudotyped retroviruses have significant advantages as reagents for the study of the biochemistry and prevention of alphavirus entry and as preferred vectors for stable gene transfer and gene therapy protocols.  (+info)

Mosquito isolates of Ross River virus from Cairns, Queensland, Australia. (8/97)

During 1996-1998 60,619 mosquitoes were collected around Cairns, Australia and processed for Alphavirus isolation. Thirty-three isolates of Ross River (RR) virus were made from 9 species, Aedes imprimens, Aedes kochi, Aedes notoscriptus, Aedes vigilax, Culex annulirostris, Culex gelidus, Mansonia septempunctata, Verrallina (formerly Aedes) carmenti, and Verrallina lineatus. Attempts to isolate RR virus from 121 Aedes aegypti were unsuccessful. Twenty-six (79%) of the isolates came from within 1 km of a colony of spectacled flying-foxes, Pteropus conspicillatus. The minimum infection rate for these mosquitoes was 1.0 compared with 0.2 per 1,000 for mosquitoes trapped at all other sites. Ross River virus has not previously been isolated from Ae. imprimens, Cx. gelidus, Ma. septempunctata, Ve. carmenti, or Ve. lineatus. This is also the first isolation of an arbovirus from Cx. gelidus in Australia. In conclusion, the vector status of Ve. carmenti, Ae. aegypti and Ma. septempunctata warrants further study. This study also provides evidence that P. conspicillatus may be a reservoir host.  (+info)

Ross River virus (RRV) is an infectious disease caused by the Ross River virus, which is a type of alphavirus. It is transmitted to humans through the bite of infected mosquitoes, primarily Aedes vigilax, Culex annulirostris, and Culex australicus in Australia.

RRV is endemic to Australia, Papua New Guinea, and some islands in the Pacific Ocean. The symptoms of RRV include fever, rash, joint pain and swelling, muscle aches, fatigue, and headache, which can last for several weeks to months. In severe cases, it can lead to chronic arthritis and other long-term complications.

There is no specific treatment for RRV, and management typically involves relieving symptoms with rest, fluids, and pain relief medications. Preventive measures include avoiding mosquito bites by using insect repellent, wearing protective clothing, and staying indoors during peak mosquito activity hours.

Alphavirus infections refer to a group of diseases caused by viruses belonging to the Alphavirus genus of the Togaviridae family. These viruses are transmitted to humans through the bite of infected mosquitoes, and can cause a range of symptoms depending on the specific virus and the individual's immune response.

Some of the more common alphaviruses that cause human disease include:

* Chikungunya virus (CHIKV): This virus is transmitted by Aedes mosquitoes and can cause a fever, rash, and severe joint pain. While most people recover from CHIKV infection within a few weeks, some may experience long-term joint pain and inflammation.
* Eastern equine encephalitis virus (EEEV): This virus is transmitted by mosquitoes that feed on both birds and mammals, including humans. EEEV can cause severe neurological symptoms such as fever, headache, seizures, and coma. It has a high mortality rate of up to 30-50% in infected individuals.
* Western equine encephalitis virus (WEEV): This virus is also transmitted by mosquitoes that feed on both birds and mammals. WEEV can cause mild flu-like symptoms or more severe neurological symptoms such as fever, headache, and seizures. It has a lower mortality rate than EEEV but can still cause significant illness.
* Venezuelan equine encephalitis virus (VEEV): This virus is transmitted by mosquitoes that feed on horses and other mammals, including humans. VEEV can cause mild flu-like symptoms or more severe neurological symptoms such as fever, headache, and seizures. It is considered a potential bioterrorism agent due to its ability to cause severe illness and death in large populations.

There are no specific treatments for alphavirus infections other than supportive care to manage symptoms. Prevention measures include avoiding mosquito bites through the use of insect repellent, wearing long sleeves and pants, and staying indoors during peak mosquito hours. Public health efforts also focus on reducing mosquito populations through environmental controls such as eliminating standing water and using insecticides.

Alphaviruses are a genus of single-stranded, positive-sense RNA viruses that belong to the family Togaviridae. They are enveloped viruses and have a icosahedral symmetry with a diameter of approximately 70 nanometers. Alphaviruses are transmitted to vertebrates by mosquitoes and other arthropods, and can cause a range of diseases in humans and animals, including arthritis, encephalitis, and rash.

Some examples of alphaviruses that can infect humans include Chikungunya virus, Eastern equine encephalitis virus, Western equine encephalitis virus, Sindbis virus, and Venezuelan equine encephalitis virus. These viruses are usually found in tropical and subtropical regions around the world, and can cause outbreaks of disease in humans and animals.

Alphaviruses have a wide host range, including mammals, birds, reptiles, and insects. They replicate in the cytoplasm of infected cells and have a genome that encodes four non-structural proteins (nsP1 to nsP4) involved in viral replication, and five structural proteins (C, E3, E2, 6K, and E1) that form the virion.

Prevention and control of alphavirus infections rely on avoiding mosquito bites, using insect repellents, wearing protective clothing, and reducing mosquito breeding sites. There are no specific antiviral treatments available for alphavirus infections, but supportive care can help manage symptoms. Vaccines are available for some alphaviruses, such as Eastern equine encephalitis virus and Western equine encephalitis virus, but not for others, such as Chikungunya virus.

I'm sorry for any confusion, but "Queensland" is not a medical term. It is the second largest state in Australia, located in the northeastern part of the country. If you have any questions about medical terms or concepts, I would be happy to help with those!

Togaviridae is a family of single-stranded, enveloped RNA viruses that includes several important pathogens affecting humans and animals. The most well-known member of this family is the genus Alphavirus, which includes viruses such as Chikungunya, Eastern equine encephalitis, Sindbis, O'nyong-nyong, Ross River, and Western equine encephalitis viruses.

Togaviridae infections typically cause symptoms such as fever, rash, arthralgia (joint pain), myalgia (muscle pain), and sometimes more severe manifestations like meningitis or encephalitis, depending on the specific virus and the host's immune status. The transmission of these viruses usually occurs through the bite of infected mosquitoes, although some members of this family can also be transmitted via other arthropod vectors or through contact with infected animals or their bodily fluids.

Prevention strategies for Togaviridae infections include using insect repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes. Vaccines are available for some members of this family, such as the Eastern and Western equine encephalitis viruses, but not for others like Chikungunya virus. Treatment is generally supportive, focusing on relieving symptoms and managing complications.

I'm sorry for any confusion, but "Rivers" is not a medical term or concept. It is a geographical term referring to large, flowing bodies of water that usually empty into a sea or an ocean. If you have any medical questions or terms you would like defined, I'd be happy to help!

Arbovirus infections are a group of diseases caused by viruses that are transmitted to humans through the bites of infected arthropods, such as mosquitoes, ticks, and midges. "Arbo" is short for "arthropod-borne."

There are over 150 different Arboviruses, but only a few cause significant illness in humans. Some of the most common Arbovirus infections include:

* Dengue fever
* Chikungunya fever
* Yellow fever
* Zika virus infection
* Japanese encephalitis
* West Nile fever
* Tick-borne encephalitis

The symptoms of Arbovirus infections can vary widely, depending on the specific virus and the individual infected. Some people may experience only mild illness or no symptoms at all, while others may develop severe, life-threatening complications.

Common symptoms of Arbovirus infections include fever, headache, muscle and joint pain, rash, and fatigue. In more severe cases, Arbovirus infections can cause neurological problems such as meningitis (inflammation of the membranes surrounding the brain and spinal cord) or encephalitis (inflammation of the brain).

There is no specific treatment for most Arbovirus infections. Treatment is generally supportive, with fluids and medications to relieve symptoms. In severe cases, hospitalization may be necessary to manage complications such as dehydration or neurological problems.

Prevention of Arbovirus infections involves avoiding mosquito and tick bites, using insect repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes and ticks. Vaccines are available to prevent some Arbovirus infections, such as yellow fever and Japanese encephalitis.

Sindbis virus is an alphavirus that belongs to the Togaviridae family. It's named after the location where it was first isolated, in Sindbis, Egypt, in 1952. This virus is primarily transmitted by mosquitoes and can infect a wide range of animals, including birds and humans. In humans, Sindbis virus infection often causes a mild flu-like illness characterized by fever, rash, and joint pain. However, some people may develop more severe symptoms, such as neurological disorders, although this is relatively rare. There is no specific treatment for Sindbis virus infection, and management typically involves supportive care to alleviate symptoms.

Climate, in the context of environmental science and medicine, refers to the long-term average of weather conditions (such as temperature, humidity, atmospheric pressure, wind, rainfall, and other meteorological elements) in a given region over a period of years to decades. It is the statistical description of the weather patterns that occur in a particular location over long periods of time.

In medical terms, climate can have significant impacts on human health, both physical and mental. For example, extreme temperatures, air pollution, and ultraviolet radiation levels associated with certain climates can increase the risk of respiratory and cardiovascular diseases, heat-related illnesses, and skin cancer. Similarly, changes in climate patterns can affect the distribution and prevalence of infectious diseases, such as malaria and Lyme disease.

Climate change, which refers to significant long-term changes in the statistical distribution of weather patterns over periods ranging from decades to millions of years, can have even more profound impacts on human health, including increased rates of heat-related illnesses and deaths, worsening air quality, and altered transmission patterns of infectious diseases.

'Culicidae' is the biological family that includes all species of mosquitoes. It consists of three subfamilies: Anophelinae, Culicinae, and Toxorhynchitinae. Mosquitoes are small, midge-like flies that are known for their ability to transmit various diseases to humans and other animals, such as malaria, yellow fever, dengue fever, and Zika virus. The medical importance of Culicidae comes from the fact that only female mosquitoes require blood meals to lay eggs, and during this process, they can transmit pathogens between hosts.

Capsid proteins are the structural proteins that make up the capsid, which is the protective shell of a virus. The capsid encloses the viral genome and helps to protect it from degradation and detection by the host's immune system. Capsid proteins are typically arranged in a symmetrical pattern and can self-assemble into the capsid structure when exposed to the viral genome.

The specific arrangement and composition of capsid proteins vary between different types of viruses, and they play important roles in the virus's life cycle, including recognition and binding to host cells, entry into the cell, and release of the viral genome into the host cytoplasm. Capsid proteins can also serve as targets for antiviral therapies and vaccines.

I apologize for any confusion, but "Australia" is not a medical term or concept. It is the world's largest island and smallest continent, located in the Southern Hemisphere, surrounded by the Pacific and Indian Oceans. It is composed of many diverse ecosystems, including deserts, rainforests, and coastal areas, and is home to a wide variety of unique plant and animal species.

If you have any questions related to medical terminology or health-related topics, I would be happy to try and help answer them for you!

"Aedes" is a genus of mosquitoes that are known to transmit various diseases, including Zika virus, dengue fever, chikungunya, and yellow fever. These mosquitoes are typically found in tropical and subtropical regions around the world. They are distinguished by their black and white striped legs and thorax. Aedes aegypti is the most common species associated with disease transmission, although other species such as Aedes albopictus can also transmit diseases. It's important to note that only female mosquitoes bite and feed on blood, while males feed solely on nectar and plant juices.

Viral envelope proteins are structural proteins found in the envelope that surrounds many types of viruses. These proteins play a crucial role in the virus's life cycle, including attachment to host cells, fusion with the cell membrane, and entry into the host cell. They are typically made up of glycoproteins and are often responsible for eliciting an immune response in the host organism. The exact structure and function of viral envelope proteins vary between different types of viruses.

I'm sorry for any confusion, but "Micronesia" is not a medical term. It is a geographical term that refers to a group of islands in the Pacific Ocean, which includes countries such as the Federated States of Micronesia, Palau, and the Marshall Islands. If you have any questions about medical terms or concepts, I would be happy to help with those!

Flavivirus infections refer to a group of diseases caused by various viruses belonging to the Flaviviridae family, specifically within the genus Flavivirus. These viruses are primarily transmitted to humans through the bites of infected arthropods, such as mosquitoes and ticks.

Some well-known flavivirus infections include:

1. Dengue Fever: A mosquito-borne viral infection that is prevalent in tropical and subtropical regions worldwide. It can cause a wide range of symptoms, from mild flu-like illness to severe complications like dengue hemorrhagic fever and dengue shock syndrome.
2. Yellow Fever: A viral hemorrhagic disease transmitted by the Aedes and Haemagogus mosquitoes, primarily in Africa and South America. It can cause severe illness, including jaundice, bleeding, organ failure, and death.
3. Japanese Encephalitis: A mosquito-borne viral infection that is endemic to Southeast Asia and the Western Pacific. While most infections are asymptomatic or mild, a small percentage of cases can lead to severe neurological complications, such as encephalitis (inflammation of the brain) and meningitis (inflammation of the membranes surrounding the brain and spinal cord).
4. Zika Virus Infection: A mosquito-borne viral disease that has spread to many regions of the world, particularly in tropical and subtropical areas. Most Zika virus infections are mild or asymptomatic; however, infection during pregnancy can cause severe birth defects, such as microcephaly (abnormally small head size) and other neurological abnormalities in the developing fetus.
5. West Nile Virus Infection: A mosquito-borne viral disease that is endemic to North America, Europe, Africa, Asia, and Australia. Most infections are mild or asymptomatic; however, a small percentage of cases can lead to severe neurological complications, such as encephalitis, meningitis, and acute flaccid paralysis (sudden weakness in the arms and legs).

Prevention measures for these diseases typically involve avoiding mosquito bites through the use of insect repellent, wearing long sleeves and pants, staying indoors during peak mosquito hours, and removing standing water from around homes and businesses. Additionally, vaccines are available for some of these diseases, such as Japanese encephalitis and yellow fever, and should be considered for individuals traveling to areas where these diseases are common.

Flavivirus is a genus of viruses in the family Flaviviridae. They are enveloped, single-stranded, positive-sense RNA viruses that are primarily transmitted by arthropod vectors such as mosquitoes and ticks. Many flaviviruses cause significant disease in humans, including dengue fever, yellow fever, Japanese encephalitis, West Nile fever, and Zika fever. The name "flavivirus" is derived from the Latin word for "yellow," referring to the yellow fever virus, which was one of the first members of this genus to be discovered.

Viral conjunctivitis is an inflammation of the conjunctiva, the thin membrane that covers the white part of the eye (sclera) and the inner surface of the eyelids, caused by a viral infection. The condition is often characterized by redness, watering, gritty or burning sensation in the eyes, and a clear, watery discharge. In some cases, it may also cause swelling of the eyelids and light sensitivity.

The most common viruses that can cause conjunctivitis are adenoviruses, which are responsible for about 65-90% of all viral conjunctivitis cases. Other viruses that can cause the condition include herpes simplex virus, varicella-zoster virus (which causes chickenpox and shingles), and picornaviruses.

Viral conjunctivitis is highly contagious and can spread easily through direct contact with infected individuals or contaminated surfaces. It typically affects one eye first and then spreads to the other eye within a few days. The condition usually resolves on its own within 1-2 weeks, although in some cases it may take longer to clear up completely.

There is no specific treatment for viral conjunctivitis, and antibiotics are not effective against viral infections. However, cool compresses and artificial tears can help alleviate symptoms such as discomfort and dryness. It is important to practice good hygiene, such as washing hands frequently and avoiding touching the eyes, to prevent the spread of the virus to others.

An exanthem is a skin eruption or rash that often occurs as a symptom of various diseases, such as infectious illnesses. It can appear in different forms, including maculopapular (consisting of both macules and papules), vesicular (small fluid-filled blisters), petechial (small purple or red spots caused by bleeding under the skin), or erythematous (reddened). The rash can be localized to certain areas of the body or generalized, covering large parts or the entire body. Exanthems are usually accompanied by other symptoms related to the underlying disease, such as fever, cough, or muscle aches.

Arboviruses are a group of viruses that are primarily transmitted to humans and animals through the bites of infected arthropods, such as mosquitoes, ticks, and sandflies. The term "arbovirus" is short for "arthropod-borne virus."

Arboviruses can cause a wide range of symptoms, depending on the specific virus and the individual host's immune response. Some common symptoms associated with arboviral infections include fever, headache, muscle and joint pain, rash, and fatigue. In severe cases, arboviral infections can lead to serious complications such as encephalitis (inflammation of the brain), meningitis (inflammation of the membranes surrounding the brain and spinal cord), or hemorrhagic fever (bleeding disorders).

There are hundreds of different arboviruses, and they are found in many parts of the world. Some of the most well-known arboviral diseases include dengue fever, chikungunya, Zika virus infection, West Nile virus infection, yellow fever, and Japanese encephalitis.

Prevention of arboviral infections typically involves avoiding mosquito bites and other arthropod vectors through the use of insect repellent, wearing long sleeves and pants, and staying indoors during peak mosquito feeding times. Public health efforts also focus on reducing vector populations through environmental management and the use of larvicides. Vaccines are available for some arboviral diseases, such as yellow fever and Japanese encephalitis.

  • A systematic analysis comparing the alphaviral glycoproteins to the vesicular stomatitis virus glycoprotein (VSV-G) revealed that lentivirus vectors incorporate RRV glycoproteins with an efficiency comparable to that of VSV-G. Both pseudotypes have comparable physical titers, but infectious titers with the RRV pseudotype are lower than with VSV-G. Incorporation of SFV glycoproteins into lentivirus vector is less efficient, leading to decreased physical and infectious titers. (elsevierpure.com)
