A number of studies indicate that clinical disease associated with BCoV in calves is more severe than rotavirus, with higher mortality rates. Linda J. Saif, in Food Animal Practice (Fifth Edition), 2009, BCoV infections are diagnosed by the detection of virus, viral antigen, or viral RNA in intestinal tissues, feces, rectal swab fluids, intestinal contents, or nasal swab fluids and secretions of infected animals. A typical outbreak lasts for 1 to 2 weeks and spreads in an epizootic manner throughout an infected herd. Bronchiolar necrosis is the typical lesion seen in BCoV-infected calves (eFig. Bovine coronavirus (BCoV) is an important cause of enteric disease in young calves, and the same strains occasionally induce respiratory disease in calves 2-16 weeks of age. coronavirus synonyms, coronavirus pronunciation, coronavirus translation, English dictionary definition of coronavirus.

Winter dysentery has also occurred in adult beef cattle and in feedlot cattle 6 to 9 months of age. In passato era classificata come genere.. Suddivisa nei generi (in passato sottogeneri) Alphacoronavirus, Betacoronavirus, Gammacoronavirus e Deltacoronavirus, questi includono genogruppi filogeneticamente compatti di … Young cattle and even calves may be affected but with only mild clinical signs. The infecting virus enters its host cell by binding to the APN receptor. Les départs et retours doivent se faire obligatoirement de la même ville. A coronavirus indistinguishable from BCoV has been isolated from wild ruminants with diarrhea similar to winter dysentery in cattle. Therefore, the upper age limit of susceptibility to infection by this agent is apparently longer than traditionally thought. BCVs are RNA viruses of the viral family Coronaviridae.6,15 They are enveloped viruses, thus sensitive to disinfectants and the environment. It is not unexpected that cattle would have a coronavirus with tropism for the respiratory tract. Only one serotype is recognized, but likely there is some antigenic variability.15 The dilemma for working with BCV experimentally and diagnostic laboratories attempting to isolate the virus is that BCV replicates poorly or is quite difficult to isolate in standard cell cultures.

An array of assays is now available for detection of bovine (or variant) coronaviruses in cell culture or diagnostic specimens such as feces or nasal swabs, including ELISAs that incorporate monoclonal antibodies for antigen capture, immune electron microscopy using hyperimmune antiserum, and RT-PCR using bovine coronavirus or pan-coronavirus-specific primers to detect viral RNA. Winter dysentery in adult cattle has been associated with BCoV, and the same strain that causes diarrhea in calves has been used to experimentally create winter dysentery in adult cattle.

Cummings, in Rebhun's Diseases of Dairy Cattle (Third Edition), 2018.

Circuits, autotours, voyage à la carte, séjours aux USA, Canada & Bahamas. Bovine coronavirus (BCV) infections in transported commingled beef cattle and sole-source ranch calves. Coronaviruses have enveloped virions that measure approximately 120 nm in diameter. Because WD is an acute, transient infection, definitive diagnosis requires submission of these specimens collected within 1 to 3 days of diarrhea onset. Further, a solubilized antigen from BCoV-infected cells combined with an oil adjuvant was tested as a prototype vaccine to be used against winter dysentery (Takamura et al., 2000, 2002). Treatment is aimed at correcting dehydration, electrolyte imbalances, and acidosis. Roniviruses usually exist as asymptomatic infections but can cause severe disease outbreaks in farmed black tiger shrimp (Penaeus monodon) and white pacific shrimp (Penaeus vannamei), which in the case of YHV can result in complete crop losses within a few days after the first signs of disease in a pond. In humans and fowl, coronaviruses primarily cause upper respiratory tract infections, while porcine and bovine coronaviruses establish enteric infections, often resulting in severe economic losses.

Rotaviruses, coronavirus, and adenoviruses affect neonatal goats; however, little has been documented on the pathology and significance of these agents in this age group. Arch Virol 2007;152:1885-1900. The BCV is considered relatively common in enteric infections in both beef and dairy operations. It was discovered in 1971 in Germany during an outbreak in sentry dogs. Postmortem diagnosis is performed on acute fresh or fixed respiratory or intestinal tissues using hyperimmune antisera or monoclonal antibodies for immunofluorescence or immunohistochemical tissue staining. A moderate immunity, which persists for about 6 months, develops after clinical disease, and recurrent clinical disease seldom occurs in less than 2 to 3 years.

Whether or not there are antigenic or genomic differences in BCoV strains that mediate different organ tropism is similarly unclear. Bronchiolar syncytia have been described in feedlot calves with concurrent BCoV infection and bacterial pneumonia, but the contribution of other viruses, such as bovine respiratory syncytial virus, to these lesions is uncertain. In a serologic survey of coronaviruses among wild deer, 8.7% and 6.6% of sera from mule deer in Wyoming and from white-tailed deer in Ohio, respectively, were seropositive against the wildlife isolates and selected bovine coronaviruses. Serologic examination of paired serum samples from affected herds reveal that almost all cows seroconvert to BCoV and BVDV. Affected calves tend to be slightly older than calves infected with pure ETEC or pure rotavirus. Milk production may not return to full capacity even after a long time of animal recovery or of that lactation. Many calves shed BCoV in their nasal secretions and/or seroconvert to BCoV in the first month after arrival in feedlots, but the association between seroconversion or virus shedding and increased risk of respiratory disease has been variable in the studies reported. Bafiniviruses have been isolated from white bream fish but there is currently no information on the pathogenesis associated with this virus infection. However, in one study, ELISA was less sensitive than IEM for detection of BCoV from WD cases, possibly because of interference by antibodies to BCoV that are widespread in cattle.8 The RT-PCR assay, based on primers to the conserved BCoV N protein gene, was more sensitive than IEM for detecting WD-BCoV in feces of experimentally inoculated calves.6, Postmortem, BCoV antigens are detected in infected intestinal epithelial cells of the distal small intestine and colon in frozen tissue sections or acetone-fixed intestinal impression smears by immunofluorescence or immunohistochemistry.2,12. A commercial ELISA kit using a pool of monoclonal antibodies to BCoV has been licensed in the United States (IDEXX, Westbrook, Me). Can J Vet Res 2011;75:191-199. J Am Vet Med Assoc 2000;216:1599-1604. In 2002, a previously unknown coronavirus that probably has its natural reservoir in bats crossed the species barrier and caused a major outbreak of SARS, which led to more than 800 deaths worldwide. BCoV may be demonstrated using immunohistochemistry or RT-PCR, or isolated using specific rectal tumor cell lines.
