1. Could human coronavirus OC43 have co-evolved with early humans?
Abstract This paper reports on an investigation of the role of codon usage evolution on the suggested bovine-to-human spillover of Bovine coronavirus (BCoV), an enteric/respiratory virus of cattle, resulting in the emergence of the exclusively respiratory Human coronavirus OC43 (HCoV-OC43). Analyses based on full genomes of BCoV and HCoV-OC43 and on both hum

2. Um enfoque multigênico para a genealogia comparada de Betacoronavirus em bovinos e equinos / A multigene approach for a compared genealogy of Betacoronavirus from cattle and horses
Gastroenteritis is one of the leading causes of morbidity and mortality amongst young and newborn animals, often caused by multiple intestinal infections, being rotavirus and Bovine coronavirus (BCoV) the main viral causes in cattle. BCoV has a worldwide distribution and caused diarrhea in calves, winter dysentery in adult cattle and respiratory disease, whi

3. An outbreak of winter dysentery caused by bovine coronavirus in a high-production dairy cattle herd from a tropical country
O coronavirus bovino (BCoV) pode causar a diarreia de inverno (WD - Winter Dysentery) ao infectar bovinos adultos, particularmente em regiões de clima temperado ou frio. A morbidade da doença é alta, resultando em queda na produção de leite e, consequentemente, perdas econômicas. No presente estudo, é descrito um surto clássico de WD acometendo um re

4. Molecular analysis of the bovine coronavirus S1 gene by direct sequencing of diarrheic fecal specimens
Bovine coronavirus (BCoV) causes severe diarrhea in newborn calves, is associated with winter dysentery in adult cattle and respiratory infections in calves and feedlot cattle. The BCoV S protein plays a fundamental role in viral attachment and entry into the host cell, and is cleaved into two subunits termed S1 (amino terminal) and S2 (carboxy terminal). Th

5. Disenteria de inverno: detecção de coronavírus bovino (BCoV) por reação de PCR dirigida ao gene Rp Rd e isolamento em cultivo celular de HRT-18G / Winter dysentery: detection of bovine coronavirus (BCoV) by RT-PCR for the Rp Rd gene and isolation in monolayers of HRT-18G cells
Bovine coronavirus (BCoV), a member of Coronaviridae family, causes severe diarrhea in newborn calves and has been associated with outbreaks of winter dysentery (WD) in adult cattle in several countries, including Brazil. The morbidity rate of WD is very high (50-100%) and the disease causes severe economic losses once it decreases milk production. The aim o

6. Detecção do coronavírus bovino em episódios de diarréia neonatal em rebanhos bovinos brasileiros
A diarréia neonatal é uma das principais causas de morbidade e mortalidade em bezerros, determinando grandes prejuízos econômicos à pecuária leiteira e de corte em todo o mundo. As causas que determinam a diarréia neonatal bovina são complexas e multifatoriais. O coronavírus bovino (BCoV) é um importante agente etiológico das diarréias virais de

7. Diagnóstico molecular e análise de polimorfismos do gene S1 de estirpes brasileiras do coronavírus bovino em fezes diarreicas de bezerros naturalmente infectados
O coronavírus bovino (BCoV) é um importante agente etiológico de diarréia neonatal em bezerros. Usualmente, as técnicas para a detecção do BCoV limitam-se a métodos de baixa sensibilidade como ensaios imunoenzimáticos e testes de hemaglutinação (HA)/ inibição da hemaglutinação (HI). Embora a PCR seja altamente sensível e específica, a nature

8. Antibody Responses of Cattle with Respiratory Coronavirus Infections during Pathogenesis of Shipping Fever Pneumonia Are Lower with Antigens of Enteric Strains than with Those of a Respiratory Strain
The serum antibody responses of cattle with respiratory coronavirus infections during the pathogenesis of shipping fever pneumonia were analyzed with different bovine coronavirus antigens, including those from a wild-type respiratory bovine coronavirus (RBCV) strain (97TXSF-Lu 15-2) directly isolated from lung tissue from a fatally infected bovine, a wild-ty

9. Isolation of coronaviruses antigenically indistinguishable from bovine coronavirus from wild ruminants with diarrhea.
Diarrheal feces from three sambar deer and one waterbuck in a wild animal habitat and one white-tailed deer on a wildlife farm in Ohio contained coronavirus particles which were agglutinated by antiserum to bovine coronavirus (BCV) in immune electron microscopy. Three coronavirus strains were isolated in human rectal tumor cells from the feces of the sambar

10. Infectivity-Neutralizing and Hemagglutinin-Inhibiting Antibody Responses to Respiratory Coronavirus Infections of Cattle in Pathogenesis of Shipping Fever Pneumonia
Respiratory bovine coronaviruses (RBCV) emerged as an infectious agent most frequently isolated from respiratory tract samples of cattle with acute respiratory tract diseases. Infectivity-neutralizing (IN) and hemagglutinin-inhibiting (HAI) antibodies induced by RBCV infections were monitored in sequential serum samples collected from cattle during a natural

11. Coronavirus and Pasteurella Infections in Bovine Shipping Fever Pneumonia and Evans' Criteria for Causation
Respiratory tract infections with viruses and Pasteurella spp. were determined sequentially among 26 cattle that died during two severe epizootics of shipping fever pneumonia. Nasal swab and serum samples were collected prior to onset of the epizootics, during disease progression, and after death, when necropsies were performed and lung samples were collecte

12. A field trial to evaluate the efficacy of a combined rotavirus-coronavirus/Escherichia coli vaccine in dairy cattle.
A field trial was designed to determine the efficacy of a combination rotavirus-coronavirus/Escherichia coli vaccine on dairy farms in southwestern Ontario. In Part A of the trial, 321 cows on 15 farms were randomly assigned to either vaccination or placebo groups. On eight farms, 50% of the dams were vaccinated, while on the other seven farms, 80% of the da
