Adaptation of very virulent infectious bursal disease virus to chicken embryonic fibroblasts by site-directed mutagenesis of residues 279 and 284 of viral coat protein VP2. (1/120)

The full-length RNA genomes of a chicken embryonic fibroblast (CEF)-nonpermissive, very virulent infectious bursal disease virus (IBDV) (strain HK46) were amplified into cDNAs by reverse transcription-PCR. The full-length cDNAs were sequenced and subcloned into a eukaryotic expression vector, from which point mutations were introduced into the VP2 region by site-directed mutagenesis. The wild-type and mutated plasmids were transfected directly into CEFs to examine their ability to generate CEF-permissive recombinant viruses. Substitution of amino acid residues 279 (Asp-->Asn) and 284 (Ala-->Thr) of the VP2 protein yielded a recombinant virus which was able to be passaged in CEFs, whereas the wild-type cDNAs and an amino acid substitution at residue 330 (Ser-->Arg) of the VP2 protein alone did not yield viable virus. The results indicated that mutation of other viral proteins, including VP1, VP3, VP4, and VP5, was not required for CEF adaptation of the virus. The same approach may be used to produce CEF-adapted strains from newly evolved IBDVs or to manipulate the antigenicity of the virus.  (+info)

Lysis of myelocytes in chickens infected with infectious bursal disease virus. (2/120)

In specific-pathogen-free chickens infected with the highly virulent HPS-2 strain or virulent reference GBF-1 strain of infectious bursal disease virus (IBDV), pathologic changes of the bone marrow were investigated. On histologic examination, bone marrow lesions were prominent in the HPS-2 group but only mild in the GBF-1 group. The bone marrow of the HPS-2 group showed severe lysis and depletion of heterophil myelocytes with pyknotic nuclear alteration 2-3 days after inoculation. On examination with an electron microscope, heterophil myelocytes were characterized by shrinkage of the cytoplasm and peripheral condensation of nuclear chromatin. IBDV particles were not detected in altered myelocytes. A terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling method demonstrated a positive reaction in only heterophil myelocytes. In contrast, nucleosomal DNA fragmentation in HPS-2-infected bone marrow cells was indiscernible by agarose gel electrophoresis. These findings indicate that lysis of bone marrow cells is selectively induced in heterophil myelocytes at an early stage after IBDV infection and independent of virus replication.  (+info)

Protection of chickens against very virulent infectious bursal disease virus (IBDV) and Marek's disease virus (MDV) with a recombinant MDV expressing IBDV VP2. (3/120)

To develop a herpes virus vaccine that can induce immunity for an extended period, a recombinant Marek's disease (MD) virus (MDV) CVI-988 strain expressing infectious bursal disease virus (IBDV) host-protective antigen VP2 at the US2 site (rMDV) was developed under the control of an SV40 early promoter. Chickens vaccinated with the rMDV showed no clinical signs and no mortality and 55% of the chickens were considered protected histopathologically after challenge with very virulent IBDV (vvIBDV), whereas all of the chickens vaccinated with the conventional IBDV vaccine showed no clinical signs and were protected. Chickens vaccinated with the CVI-988 or chickens in the challenge control showed severe clinical signs and high mortality (70-75%) and none of them were protected. Also, the rMDV conferred full protection to chickens against vvMDV just as the CVI-988 strain did, whereas 90% of the challenge control chickens died of MD. Antibody levels against IBDV and MDV following the vaccination increased continuously for at least 10 weeks. No histopathological lesions in the rMDV-vaccinated chickens and no contact transmission of the rMDV to their penmates were confirmed. These results demonstrate that an effective and safe recombinant herpesvirus-based IBD vaccine could be constructed by expressing the VP2 antigen at the US2 site of the CVI-988 vaccine strain.  (+info)

Sequence comparison of the VP2 variable region of infectious bursal disease virus isolates from Vietnam. (4/120)

The variable region in the VP2 gene of twenty-three infectious bursal disease virus (IBDV) isolates, collected in Vietnam in 1997 and 1998, was amplified as cDNA by using the reverse transcription-polymerase chain reaction and sequenced. Analysis of amino acid substitutions and phylogenetic relationships of the deduced amino acid sequences (residues 206-350) showed that the nineteen Vietnamese vv IBDVs clustered with the European vv IBDVs, Japanese vv IBDVs and Chinese vv strains, and that the four vietnamese virulent strains were closely related to European virulent strain 52/70. These results suggest that Vietnamese vv IBDVs, European vv IBDVs, Japanese vv IBDVs and Chinese vv strains have the same origin.  (+info)

Gill lamellar pillar cell necrosis, a new birnavirus disease in Japanese eels. (5/120)

Since the late 1980s, a birnaviral gill disease has been occurring in Japanese eels Anguilla japonica reared in warmwater ponds in western regions in Japan. Diseased eels mostly displayed marked formations of aneurysmal hematomas within gill lamellae and high mortalities. Histological examination revealed necrosis of pillar cells and subsequent aggregation of erythrocytes inside the lamellar capillaries, and proliferation of interlamellar epithelia onto the lamellae. Gastric gland cells were also necrotized. Electron microscopy revealed birnavirus infection in lamellar pillar cells. The causative birnavirus was isolated and cultured in fish cell lines and was found to be related to an infectious pancreatic necrosis virus (IPNV) Sp serotype by neutralization tests. The viral pathogenicity was confirmed by the results of histopathological examinations and infectivity experiments.  (+info)

Effect of thymus extract on immunologic reactivity of chicken vaccinated with infectious bursal disease virus. (6/120)

The effects of crude thymus extract on the immune response and protection against challenge with virulent infectious bursal disease virus (IBDV) were studied in one-day-old chick. Oral administration of thymus extract (1 ml/kg) markedly and significantly increased the total protein, albumin, globulin, Tri-iodothyronine (T3), Thyroxine (T4) and the body weight gain in one-day-old chick. In addition, it increased the total lymphocytic count over four weeks after administration. Although vaccination also increased total protein, globulin, T4 and the total lymphocytic count but it significantly decreased the body weight gain of the chick and administration of thymus extract, before, during or after vaccination markedly improved the vaccination effectiveness with significant elevation of the globulin level and body weight gain of the chick. It also prevented the decrease in the relative weights of bursa, spleen and thyroid gland which commonly prevailed during vaccination. Chicken administered thymus extract and vaccinated with infectious bursal disease (IBD) vaccine showed 100% protection against challenge with IBDV. Meanwhile the vaccinated non-thymus treated group exhibited 80% protection against IBDV challenge. These results indicate a potentiating effect of thymus extract on the immune system in baby chick. These findings are supported by ELISA results that showed a marked increase in antibody titers in thymus treated groups. Additionally, microscopical examination of the bursa and the existent lymphoid hyperplasia in thymus treated groups but not vaccinated group support our findings.  (+info)

Inter-laboratory comparison of cell lines for susceptibility to three viruses: VHSV, IHNV and IPNV. (7/120)

Eleven European National Reference Laboratories participated in an inter-laboratory comparison of the susceptibility of 5 selected cell lines to 3 fish pathogenic viruses. The test included viral hemorrhagic septicaemia virus (VHSV); infectious hematopoietic necrosis virus (IHNV) and infectious pancreatic necrosis virus (IPNV), and the cell lines derived from bluegill fry (BF-2), chinook salmon embryo (CHSE-214), epithelioma papulosum cyprini (EPC), fathead minnow (FHM) and rainbow trout gonad (RTG-2). The results showed that for isolation of VHSV, BF-2 and RTG-2 cells performed equally well and had higher sensitivity compared to the other cell lines. For IHNV, EPC and FHM cells gave the best results, and for IPNV it was BF-2 and CHSE-214 cells. FHM cells showed the largest variability among laboratories, whereas EPC was the cell line showing the smallest variability.  (+info)

Multiplex reverse transcriptase PCR assay for simultaneous detection of three fish viruses. (8/120)

A multiplex reverse transcriptase (RT)-PCR assay was developed for the simultaneous detection of three different fish viruses: infectious pancreatic necrosis virus (IPNV), infectious hematopoietic necrosis virus (IHNV), and viral hemorrhagic septicemia virus (VHSV). The sensitivity levels of the multiplex RT-PCR assay were 100, 1, and 32 50% tissue culture infective doses/ml for IPNV, IHNV, and VHSV, respectively.  (+info)

Birnaviridae is a family of non-enveloped, double-stranded RNA viruses that infect a wide range of animals, including birds, fish, and insects. The name Birnaviridae comes from the combination of the words "bird" and "RNA." These viruses are characterized by their icosahedral symmetry and bi-segmented genome, which is composed of two segments of double-stranded RNA.

The two genomic segments of Birnaviridae encode for several viral proteins, including the viral capsid protein and the RNA-dependent RNA polymerase (RdRp) that is responsible for replicating the viral genome. The family Birnaviridae includes several important veterinary pathogens, such as infectious bursal disease virus (IBDV), which causes a highly contagious and often fatal disease in young chickens, and aquabirnavirus, which infects various species of fish and can cause significant economic losses in the aquaculture industry.

Birnaviruses are typically transmitted through fecal-oral routes or by ingestion of contaminated food or water. They replicate in the cytoplasm of infected cells and can induce a range of clinical signs, depending on the specific virus and host species. In addition to their veterinary importance, birnaviruses are also of interest to researchers studying the fundamental biology of RNA viruses and their interactions with host cells.

Birnaviridae is a family of viruses that includes several species known to cause infections in animals, including birds and fish. The most well-known member of this family is the infectious bursal disease virus (IBDV), which primarily affects young chickens and causes a highly contagious disease known as Gumboro disease.

Infection with IBDV can result in a range of symptoms, including diarrhea, depression, ruffled feathers, and decreased appetite. In severe cases, the virus can cause significant mortality in infected flocks. Other members of the Birnaviridae family include viruses that infect salmonids (such as infectious pancreatic necrosis virus) and other bird species.

Transmission of Birnaviridae viruses typically occurs through direct contact with infected animals or their feces, as well as through contaminated food and water sources. Prevention and control measures for these infections include good biosecurity practices, vaccination, and proper nutrition and management.

An Aquabirnavirus is a type of double-stranded RNA virus that belongs to the family Birnaviridae. The name "Aquabirnavirus" reflects its prevalence in aquatic environments. These viruses are known to infect a variety of hosts, including fish and crustaceans. They have an icosahedral symmetry and a non-enveloped capsid. The genome of Aquabirnaviruses consists of two segments of double-stranded RNA. The larger segment encodes the viral polyprotein, while the smaller segment encodes the viral capsid protein. Aquabirnaviruses are relatively resistant to environmental factors such as heat, pH, and organic solvents, which allows them to persist in aquatic environments for extended periods.

Infectious Bursal Disease Virus (IBDV) is a highly contagious avian virus that primarily affects the bursa of Fabricius in young chickens, leading to an immunosuppressive disease known as Gumboro disease. The bursa of Fabricius is a vital organ for the development and maturation of B cells, which are crucial for the immune system's response to infections.

IBDV is a non-enveloped, double-stranded RNA virus belonging to the Birnaviridae family. It has two serotypes, with serotype 1 being responsible for the majority of outbreaks and being highly pathogenic, while serotype 2 is less virulent and causes mild or asymptomatic infections.

The virus targets and destroys the B cells in the bursa, leading to a weakened immune system that makes the affected chickens more susceptible to secondary bacterial and viral infections. The disease can cause significant economic losses in the poultry industry due to high mortality rates, decreased feed conversion efficiency, and reduced egg production.

Vaccination is an effective prevention strategy against IBDV, with both live and inactivated vaccines available for use in chickens. Good biosecurity measures, such as strict sanitation practices and limiting the movement of birds and people between farms, can also help prevent the spread of the virus.

Infectious pancreatic necrosis (IPN) is a viral disease that primarily affects young salmonid fish, such as salmon and trout. The IPN virus, also known as Salmonid alphavirus (SAV), is the causative agent of this disease. It is an enveloped, positive-sense single-stranded RNA virus belonging to the family Alphaflexiviridae and genus Alphavirus.

The IPN virus primarily targets the exocrine pancreas, leading to severe necrosis (tissue death) in infected fish. The infection can also spread to other organs, including the liver, kidney, and heart. Infected fish may exhibit various clinical signs such as lethargy, loss of appetite, darkening of the skin, abnormal swimming behavior, and exophthalmia (bulging eyes).

The IPN virus is highly contagious and can be transmitted horizontally through direct contact with infected fish or their bodily fluids. It can also be vertically transmitted from infected broodstock to their offspring. The disease can have significant economic impacts on the aquaculture industry, leading to high mortality rates in affected fish populations.

Prevention and control measures for IPN include vaccination of broodstock and fry, biosecurity practices, and quarantine procedures. There is no specific treatment for IPN, and antibiotics are generally not effective against viral infections. Supportive care, such as providing optimal water quality and nutrition, can help affected fish recover from the disease.

Viral structural proteins are the protein components that make up the viral particle or capsid, providing structure and stability to the virus. These proteins are encoded by the viral genome and are involved in the assembly of new virus particles during the replication cycle. They can be classified into different types based on their location and function, such as capsid proteins, matrix proteins, and envelope proteins. Capsid proteins form the protein shell that encapsulates the viral genome, while matrix proteins are located between the capsid and the envelope, and envelope proteins are embedded in the lipid bilayer membrane that surrounds some viruses.

Molecular sequence data refers to the specific arrangement of molecules, most commonly nucleotides in DNA or RNA, or amino acids in proteins, that make up a biological macromolecule. This data is generated through laboratory techniques such as sequencing, and provides information about the exact order of the constituent molecules. This data is crucial in various fields of biology, including genetics, evolution, and molecular biology, allowing for comparisons between different organisms, identification of genetic variations, and studies of gene function and regulation.

RNA-dependent RNA polymerase, also known as RNA replicase, is an enzyme that catalyzes the production of RNA from an RNA template. It plays a crucial role in the replication of certain viruses, such as positive-strand RNA viruses and retroviruses, which use RNA as their genetic material. The enzyme uses the existing RNA strand as a template to create a new complementary RNA strand, effectively replicating the viral genome. This process is essential for the propagation of these viruses within host cells and is a target for antiviral therapies.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
