analysis of the genomes of bluetongue virus serotype 10 vaccines and a recent btv-10 isolate from washington.the 10 double-stranded rna gene segments of 2 vaccinal strains of bluetongue virus (btv) serotype 10 that are used in the united states (btv ca8 california and bt-8 colorado), and a btv-10 isolate recently obtained from infected sheep in washington (state) were characterized by oligonucleotide fingerprint analyses. it was determined that although the 2 btv-10 vaccinal strains are genotypically distinct, they are closely related both to each other and to the united states prototype btv-10 virus. ...19836299144
fatal pneumonia of bighorn sheep following association with domestic sheep.during 1979-1980 acute fibrinopurulent bronchopneumonia resulted in high mortality or total loss of herds of bighorn sheep (ovis canadensis) in california and washington. contact with domestic sheep occurred shortly before the onset of disease in each case. circumstantial evidence indicated that the apparently healthy domestic sheep transmitted pathogenic bacteria to the bighorns, resulting in mortality. pasteurella multocida and corynebacterium pyogenes were isolated from pulmonary tissue of de ...19827047767
bighorn sheep, a new host record for parelaphostrongylus odocoilei (nematoda: protostrongylidae).larval nematodes with a dorsal spine on the tail were recovered from fecal samples of california bighorn sheep (ovis canadensis californiana) in northeastern washington state, usa. the identity of these dorsal-spined larvae (dsl) was established by single-strand conformation polymorphism (sscp) analyses of a partial fragment of the first internal transcribed spacer of the ribosomal dna. the sscp profiles of individual dsl from bighorn sheep were compared with those of dsl of five protostrongylid ...200617255460
