| antigenic relationship of turkey coronavirus isolates from different geographic locations in the united states. | the purpose of the present study was to examine the antigenicity of turkey coronavirus (tcv) isolates from various geographic areas with antibodies to different viruses. seventeen isolates of tcv were recovered from intestinal samples submitted to animal disease diagnostic laboratory, purdue university, from turkey farms located in different geographic areas. the prototype tcv minnesota isolate (tcv-atcc) was obtained from the american type culture collection. intestinal sections were prepared f ... | 2002 | 12061660 |
| genotyping of turkey coronavirus field isolates from various geographic locations in the unites states based on the spike gene. | turkey flocks have experienced turkey coronaviral enteritis sporadically in the united states since the 1990s. twenty-four field isolates of turkey coronavirus (tcov) from multiple states in the united states were recovered from 1994 to 2010 to determine the genetic relationships among them. the entire spike (s) gene of each tcov isolate was amplified and sequenced. pairwise comparisons were performed using the clustal w program, revealing 90.0% to 98.4% sequence identity in the full-length s pr ... | 2015 | 26254026 |
| comparison of 3'-end encoding regions of turkey coronavirus isolates from indiana, north carolina, and minnesota with chicken infectious bronchitis coronavirus strains. | to analyze the 3'-end structural protein-encoding region of turkey coronavirus (tcov) isolates associated with outbreaks of acute enteritis in indiana, north carolina, or minnesota. | 2006 | 16491018 |
| detection of turkey coronaviral enteritis (bluecomb) in field epiornithics, using the direct and indirect fluorescent antibody tests. | in minnesota, efforts have been made over the past 10 years to eliminate turkey coronaviral enteritis (tce, bluecomb) by controlled depopulation and decontamination with a rest period before restocking. in 1973, clinical observations indicated that bluecomb was restricted to one limited area in minnesota. five epiornithics occurred during late 1973 and 1974, involving 5 different farms in this limited geographic area. during 1975, 3 epiornithics of tce were investigated, involving 185,000 turkey ... | 1977 | 200156 |
