Molecular identification of Taenia spp. in the Eurasian lynx (Lynx lynx) from Finland.

abstract：:We cloned and expressed Echinostoma caproni HSP70 in Escherichia coli. This molecule presents an open reading frame (ORF) of 655 amino acids, and a theoretical molecular weight of 71 kDa. E. caproni HSP70 protein showed a high homology to other helminth molecules, major differences being located in the C-terminal regi...

abstract：:Ornithodoros moubata ticks were fed on blood infected with Babesia equi. However, the parasites were quickly cleared as evidenced by the disappearance of B. equi-specific ribosomal RNA from the ticks. We hypothesized that if the Babesia parasite can escape midgut-associated barriers a non-vector tick can become infect...
