Based on plaque morphology - these initial efforts are focused on selecting plaque size mutants (large plaques of greater than 5mm diameter vs. small plaques of less than 1 mm diameter) - at least 3 separate samples of each, large and small, were selected for further development. Furthermore, critical issues on its survival and inactivation have been ImpactsWhat was accomplished under these goals? Nothing Reported Samples of viral mRNA during growth studies are being collected and analysis of those will be undertaken in the next reporting period. Learning more about this in FCV will help inform studies with the many other important virus pathogens with similar ss(+)RNA genomes causing problems in animals and humans. Positive-stranded RNA virus transcription is the method of transcription. In humans, caliciviruses are a major cause of acute gastroenteritis, while in animals respiratory illness, conjunctivitis, stomatitis, and hemorrhagic disease are documented. Yu G, Zhang D, Guo F, Tan M, Jiang X, Jiang W (2013) Cryo-EM structure of a novel calicivirus, Tulane Virus. There is no evidence that other cat coronaviruses such as the Feline coronavirus UU21, or Feline infectious peritonitis virus, can infect humans or cause any cross-protection against SARS-CoV-2. How have the results been disseminated to communities of interest? However, cats in crowded or stressful conditions or with weak immune systems often develop more severe symptoms, as can kittens, Persians and other flat-face breeds. Humans and dogs are not at risk for catching feline herpes, and cats cannot catch the strains of herpes that humans carry. Changes/Problems:The P.I. The generation of plaque mutants will continue to maintain stable populations, and to 'drive' continual mutation to further develop the mutant bank for looking at the evolution of pathogenesis and virulence of FCV. Using feline calicivirus (FCV) as the study system, plaque size mutants or variants were studied. Changes/Problems: The project timeline has been slowed for two reasons. The source of caliciviruses causing gastroenteritis in humans is frequently shellfish, which do not always come from beds contaminated with human waste ( 3 , 4 ). The virus is able to mutate/change over time (similar to human flu virus) which is why cats that have recovered from calicivirus or are vaccinated may still get mild symptoms if they are re-infected with a new strain. Progress 11/20/13 to 09/30/18OutputsTarget Audience: Feline calicivirus is resistant to many disinfectants and can survive outside a cat’s body for several days. Vaccines that protect against feline viral rhinotracheitis and feline calicivirus are available. Establishing stable plaque variants serial plaque purification (FCV passaged in Crandell-Rees Feline Kidney cells - CRFK cells) has proven challenging as reducing the variation in plaque size requires at least 15 serial purification steps. Changes/Problems:The P.I. was on sabbatical during the first 3 months of the reporting period, somewhat slowing progress, What opportunities for training and professional development has the project provided? The first mouse norovirus, murine norovirus 1 (MNV-1), was discovered in 2003. Nothing Reported Publications, National Institute of Food and Agriculture. The Caliciviridae are a family of viruses, members of Class IV of the Baltimore scheme. Cats that have received the nasal vaccine may sneeze frequently for a few days after vaccination; ask your veterinarian if you should expect this or any other side effect from the vaccines. The initial sequence efforts were unsuccessful; however, new samples have been generated and are currently being sequenced. Feline Calicivirus Disease Overview Calicivirus is a common virus in cats that causes upper respiratory infection. How have the results been disseminated to communities of interest? FCV-genomic and mRNA samples were collected for sequence analysis. Approximately 10% of cats housed in small groups are infected, while up to 90% of those housed in more crowded conditions, such as in shelters and breeding catteries, may be infected. Nothing Reported Feline calicivirus (FCV) is one of the major causes of feline infectious upper respiratory tract disease (cat flu). Like upper respiratory infections in humans, the infection will cause most cats to exhibit symptoms such as congestion and eye problems. PLoS One 8(3):e59817. Cheetahs are the other species of the family Felidae known to become infected naturally. The principal diseases, feline viral rhinotracheitis (FVR; feline herpesvirus type 1), feline calicivirus (FCV), Chlamydia felis, Mycoplasma felis, or combinations of these infections, affect exotic as well as domestic species. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported This research is aimed at understanding some of the dynamics of virus adaptation associated with increasing or decreasing virulence. It is a member of the Caliciviridae family. The caliciviruses, family Caliciviridae, include important pathogens of humans and animals. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported The virus is present in saliva, tears and nasal secretions and spread through contact between cats. Members of other genera, Norovirus and Sapovirus, cause gastrointestinal disease in humans. Changes/Problems: Consistently, the FCV-Lg variants replicated faster and to higher titers. Feline picornavirus Feline calicivirus is a virus of the family Caliciviridae that causes disease in cats. The feline calicivirus (FCV) is one of several viruses that can cause upper respiratory infections in cats. And it is the same coronavirus that infects people. Feline calicivirus, a member of the genus Vesivirus, causes respiratory disease in cats. For diagnosis, pay attention to symptoms in your cat, and if you suspect that your cat has been affected, take it to … A drug used to treat coronavirus infections in cats may soon be used to treat Covid-19 in humans, after researchers showed the drug works against the SARS-CoV2 coronavirus in laboratory experiments. Generation and purificationofplaque variants of FCVwill be competedand sequencing of their genomes will begin. FCV causes about half of the respiratory infections that occur in cats, but feline alphaherpesvirus1 (sometimes called feline rhinotracheitis virus) is another common cause and sometimes dual infections occur. These symptoms emerge after an incubation time of 2 days and the symptoms only generally last for 3 days. Bartonella species, feline calicivirus, and feline herpesvirus 1 infection with gingivo-stomatitis in cats. Comparison of the RNA from FCV mutants will be initiated by 1) sequence analysis of 3 large- and 3 small-plaque variants and2) continued comparison of replication rates and efficiencies in CRFK cells using cell culture-based techniques and RT-PCR of mRNA expression. The cats, once infected, shed virus particles in the same way that humans do. Feline calicivirus. What opportunities for training and professional development has the project provided? The human caliciviruses, like other members of the family Caliciviridae, are small (approximately 27 nm), nonenveloped RNA viruses with a single major capsid protein. Feline calicivirus (the only member of the group with a seemingly ubiquitous and continuous terrestrial presence) also appears to have ocean reservoirs . Nothing Reported FCV plaques variants were and are being regenerated as frozen stocks of previously plaque-purified variants were no longer stable. Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?The generation of plaque mutants will continue to maintain stable populations. No. Norovirus, except its natural hosts humans and experimental host chimpanzees, neither of which is available for disinfectant efficacy testing on ethical grounds10.

PetAirapy’s UV technology has been designed and tested to quickly deliver high disinfection rates of feline calicivirus and other microorganisms that spread infection in animal care facilities. The following symptoms typically present themselves suddenly: 1. ImpactsWhat was accomplished under these goals? Calicivirus and other feline URIs are highly contagious infections that can result in mild to severe clinical signs (especially in immunosuppressed or very young kittens). We investigated eligibility of FCV for anti-viral assay by investigating the stability of infectivity and pH sensitivity in comparison with other viruses. This selection and purification process continues to maintain distinct genomic variants. Since then, numerous murine norovirus strains have been identified and they were assigned a new genogroup in the genus Norovirus. Calicivirus infections commonly cause acute gastroenteritis, which is the inflammation of the stomach and intestines (e.g. The dictionary of virology, 4th edition. Replication follows the positive-stranded RNA virus replication model. [4] A recent isolate from rhesus monkeys—Tulane virus—can be grown in culture, and this system promises to increase understanding of these viruses.[5]. Dictionary ... of cats against feline viral rhinotracheitis (feline viral rhinotracheitis (feline herpes virus type I) and feline calicivirus infections. Sapovirus, Norovirus, and Vesivirus have been detected in pigs, making this animal species of particular interest in the study of calicivirus pathogenesis and host range. What do you plan to do during the next reporting period to accomplish the goals?Analysis of available calicivirus genome sequenceswill continue. Feline calicivirus (FCV)—a member of the Vesivirus—represents an important pathogen of cats. Pet owners should always bring their cat to see the veterinarian if it shows signs of respiratory disease. The vesiviruses include feline calicivirus … How have the results been disseminated to communities of interest? Most calicivirus infections do not call for medical attention, but those who are immunocompromised may need to be hospitalized for rehydration therapy. The Caliciviridae are a family of viruses, members of Class IV of the Baltimore scheme. However, the recent application of modern genomic technologies has led to an increased understanding of the virus family. Feline calicivirus is a highly contagious and common virus in cat populations worldwide. They are positive-sense, single-stranded RNA which is not segmented. Preliminary analysis of the replication using routine cell culture growth curves of the FCV mutants in CRFK cells confirmed previous studies showing faster replication rates in larger (greater than 5mm diameter) plaque variants when compared to small plaque variants (less than 1 mm in diameter). Entry into the host cell is achieved by attachment to host receptors, which mediate endocytosis. Several mutants have been selected and analysis on their biology has been initiated. J Feline Med Surg 2010; 12: 314–321. The PI is on sabbatical leave during 2015, but upon his return in January of 2016 will begin analysis of the plaque variants' replication characteristics and gene expression. Calicivirus, includes Norovirus, is an RNA virus that is one of the principal causes of foodborne diseases, which result in stomach ache, abdominal pain, diarrhea, vomiting, headache, and mild fever. It is one of the two important viral causes of respiratory infection in cats, the other being Felid alphaherpesvirus 1. Top. Published genomic sequences of feline calicivirus (FCV), and other caliciviruses, were and are being analyzed using for sequence and potential functional differences. Vertebrates serve as the natural host. Nothing Reported The bacterial species Chlamydia felis and Mycoplasma felis also cause respiratory disease, and may complicate FCV infections. FCV can be isolated from about 50% of cats with upper respiratory infections. The caliciviruses have a simple construction and are not enveloped. Lethal outbreak of disease associated with feline calicivirus infection in cats.Vet Rec 2006; 158: 544–550. Analysis of biological characteristics was conducted, including growth rates, the number of infectious particles, cytopathogenic effects, and proteins expressed.

One type is injected; the other is given as drops in the nose. Feline calicivirus is a virus that is an important cause of upper respiratory infections and oral disease in cats. Symptoms can include vomiting and diarrhea. DOI: 10.3201/eid1512.e11512. This article was most recently revised and updated by Kara Rogers, Senior Editor. Thirteen species are placed in this family, divided among eleven genera. Objective 1: The goal of this research was to better understand the role of evolution, through genomic mutation, involved in the pathogenesis and virulence of RNA viruses. [1] Thirteen species are placed in this family, divided among eleven genera. the Norwalk virus). The biological analysis showed the virus did adapt to the non-feline cells after 20 passages, and the biological changes were similar to the differences between FCV-Sm and FCV-Lg: i.e., the FCV grown in cat cells grew faster and to higher titers. FCV-genomic and mRNA samples have been collected and will be sequenced during the next reporting period. Feline calicivirus causes FCV, with the usual symptoms including: Nasal discharge Gingivitis Mouth ulcers Publications, Progress 10/01/16 to 09/30/17OutputsTarget Audience: was on sabbatical all of 2015, thus the project has been slowed. Nothing Reported Consistent plaque variants of large (FCV-Lg; greater than 5 mm in diameter) and small (FCV-Sm; less than 2 mm in diameter) have been produced and analysis was done. The presence of typical signs of URI is enough for a presumptive diagnosis of FHV (and/or feline calicivirus – FCV) infection. ImpactsWhat was accomplished under these goals? Nothing Reported Publications, Progress 10/01/14 to 09/30/15OutputsTarget Audience: Consistent plaque variants of large (greater than 5 mm in diameter) and small (less than 2 mm in diameter) have been produced and analysis has been initiated. How have the results been disseminated to communities of interest? Feline calicivirus (FCV) is a virus that infects domestic cats, causing a range of flu-like symptoms. We found that infectivities of FCV and murine norovirus (MNV) are … Publications, Progress 11/20/13 to 09/30/14OutputsTarget Audience: In addition, FCV has been passaged in non-feline cell cultures (canine and primate cells) to generate culture-specific strains of virus. The capsid appears hexagonal/spherical and has icosahedral symmetry (T=1 or T=3[3]) with a diameter of 35–39 nm. In addition, large and small plaque variants are being serially passaged through CRFK cells to generate a temporal library of viruses that will be studied for genomic changes over time. MENTAL health symptoms such as depression and anxiety can be triggered in humans who have been in “close contact” with cats, experts have warned. What does calicivirus mean? Calicivirus (FCV) is a common viral infection found in cats that is characterised by the presence of flu-like symptoms such as upper respiratory infection. [2] Diseases associated with this family include feline calicivirus (respiratory disease), rabbit hemorrhagic disease virus (often-fatal hemorrhages), and Norwalk group of viruses (gastroenteritis). Virus growth studies in CRFK cells have been performed, initial studies looked at plaque-variant growth rates, identification of FCV-specific RNA in cells, and temporal expression of FCV-specific proteins in CRFK cells. In humans, the genera Norovirus and Sapovirus are the most common cause of infectious gastroenteritis - for example, the "cruise ship virus". To study this, the impact of mutation on FCV replication is being examined through the development of plaque morphology (size) mutants or variants. Nothing Reported A veterinarian will examine t… [2][3] Caliciviruses naturally infect vertebrates, and have been found in a number of organisms such as humans, cattle, pigs, cats, chickens, reptiles, dolphins and amphibians. At the start of the reporting period the PI began the process of regenerating variants using standard plaque-purification techniques. The viral proteins expressed were similar in number and size, although the capsid protein of the FCV-Lg variants had a higher molecular weight, which supports previous research reporting a difference in molecular mass of the capsid proteins when comparing large and small plaque variants. Australia and New Zealand, in an effort to control their rabbit populations, have intentionally spread calicivirus. Feline calicivirus causes FCV, with the usual symptoms including: Nasal discharge Gingivitis Mouth ulcers The name calicivirus is derived from the Greek word calyx meaning cup or goblet, due to many strains having visible cup-shaped depressions. Nothing Reported Plaque purification, along with generation of additional mutants, will continue following the PI's 2015 sabbatical. Transmission routes are fecal-oral.[3]. Feline calicivirus (FCV) is frequently used as a surrogate of human norovirus. 7 Coyne KP, Jones BR, Kipar A, Chantrey J, Porter CJ, Barber PJ, et al. Norovirus spreads by contact with an infected person, particularly in crowded places, and also by the intake of infected food. In animals, the genus Vesivirus most consistently causes vesicular blisters (vesicles) and ulcerations. The goal of this research is to better understand the role of evolution, through genomic mutation, involved in the pathogenesis and virulence of RNA viruses. URIs are the human equivalent of the common cold. Nothing Reported Mutants have been generated by serial plaque purification in CRFK (Crandell-ReesFeline kidney) cells. Diseases associated with this family include feline calicivirus (respiratory disease), rabbit hemorrhagic disease virus (often-fatal hemorrhages), and Norwalk group of viruses (gastroenteritis). Initial efforts are focused on the capsid gene (ORF-2) because previous research has shown a difference in molecular mass of the capsid proteins when comparing large and small plaque variants. Menu. Using the feline calicivrus (FCV) as a model system, this research has started looking at mutations/changes n the FCV genome/genetic information, how those mutations might impact the virus's ability to cause disease or the severity of the disease, and possible mechanisms to help explain why some genetic variants cause more severe disease than others. Nothing Reported What do you plan to do during the next reporting period to accomplish the goals? Sources: Mahy BWJ. CATS may be able to spread coronavirus to humans despite showing no symptoms, experts have warned. ImpactsWhat was accomplished under these goals? Establishing stable plaque variants serial plaque purification (FCV passaged in Crandell-Rees Feline Kidney cells - CRFK cells) proved challenging as reducing the variation in plaque size requires at least 15 serial purification steps. Cats can easily transmit URIs, like calicivirus. Using feline calicivirus (FCV) as the study system, plaque size mutants or variants have been developed. First, because previously generated plaque variants were no longer "pure", it was/is necessary to regenerate the variants. Second, the PI is on sabbatical all of 2015. Symptoms usually do not last longer than 3 days. Headache and myalgia may also be present. Publications, Progress 10/01/15 to 09/30/16OutputsTarget Audience: The impact of this research is mostly in the development of research samples and baseline information for future molecular biology studies of the influence of evolution of viruses on their ability to spread through populations and their ability to cause disease. Changes/Problems: [4], Caliciviruses are not very well studied because until recently, they could not be grown in culture, and no suitable animal model has been found. A number of other caliciviruses remain unclassified, including the chicken calicivirus. Cite This Article. Rabbit hemorrhagic disease virus is a pathogen of rabbits that causes major problems throughout the world where rabbits are reared for food and clothing, make a significant contribution to ecosystem ecology, and where they support valued wildlife as a food source.[4]. FCV mutants analysis will continue using 1) genomic and mRNA sequence analysis of large- and small-plaque variants collected during growth studies in CRFK cells, and 2) continued comparison of replication rates and efficiencies in CRFK cells using cell culture-based techniques and RT-PCR of mRNA expression. Dictionary ! ImpactsWhat was accomplished under these goals? If a specific diagnosis is required, ocular or oral swabs can be submitted to a veterinary laboratory where the virus can be grown in culture or, more commonly, detected by PCR (a molecular technique for detecting the genetic material of the virus). All viruses in this family possess a nonsegmented, polyadenylated, positive-sense, single-strand RNA genome around 7.5–8.5 kilobases in length, enclosed in an icosahedral capsid of 27–40 nanometers in diameter. What opportunities for training and professional development has the project provided?Three undergraduate students, Microbiology majors, starting working on this project in August of 2018 and are continuing through the 2019-19 school year. In order to study the effects of mutation on replication, and possibly virulence, of FCV, new sets of plaque variants need to be generated. It’s very common in cats and kittens and is usually caused by either the feline herpes virus (FHV) or feline calicivirus (FCV). Classical cat ‘flu’ follows a short incubation period of 3–5 days and consists predominantly of upper respiratory tract disease (sneezing, rhinitis, nasal discharge, conjunctivitis, ocular discharge and oral ulceration). Translation takes place by leaky scanning, and RNA termination-reinitiation. How have the results been disseminated to communities of interest? Feline calicivirus (FCV) is an agent that causes upper respiratory disease in cats. They are positive-sense, single-stranded RNA which is not segmented. Viral replication is cytoplasmic.
