Nucleotide sequence of the bovine enteric coronavirus BECV F15 mRNA 5 and mRNA 6 unique regions

The nucleotide sequence and spliced pol mRNA levels of the nonprimate spumavirus bovine foamy virus.

We have determined the complete nucleotide sequence of a replication-competent clone of bovine foamy virus (BFV) and have quantitated the amount of splice pol mRNA processed early in infection. The 544-amino-acid Gag protein precursor has little sequence similarity with its primate foamy virus homologs, but the putative nucleocapsid (NC) protein, like the primate NCs, contains the three glycine...

Nucleotide sequence of murine ornithine decarboxylase mRNA.

Ornithine decarboxylase (OrnDCase; L-ornithine carboxy-lyase, EC 4.1.1.17) is the first and rate-limiting enzyme in the biosynthesis of polyamines in mammalian cells. During cell growth the enzyme is regulated by rapid changes in the level of its mRNA and protein. To explore the molecular basis of these changes, we cloned a full-length cDNA copy of the major 2.4-kilobase OrnDCase mRNA from mous...

Coronavirus in Gnotobiotic Calves Coronavirus and a Virulent Bovine Enteric Cross-Protection against a Human Enteric

Cross-protection against a human enteric coronavirus and a virulent bovine enteric coronavirus in gnotobiotic calves.

A group 2 human coronavirus designated HECV-4408 was isolated from a child with acute diarrhea and is antigenically and genetically more closely related to bovine coronavirus (BCoV) than to human coronavirus OC43 (X. M. Zhang, W. Herbst, K. G. Kousoulas, and J. Storz, J. Med. Virol. 44:152-161, 1994). To determine whether HECV-4408 infects gnotobiotic calves and induces cross-protective immunit...
