Cover Story: Tick cell lines are important tools for research on ticks and the pathogens they transmit, facilitating laboratory-based isolation, propagation, and study of disease-causing agents, as well as aspects of tick biology. This study reports ten new cell lines derived from embryos of five genera of European ticks. Each cell line was generated from a primary culture comprising a wide variety of cell phenotypes, of which only some started to grow continuously. Molecular analysis confirmed the species origin of each cell line and revealed genetic differences between cell lines derived from ticks collected in the same or nearby geographic locations. Collectively, these new cell lines will support research into a wide range of viral, bacterial, and protozoal tick-borne diseases prevalent in Europe. View this paper

  • Yanwen Xiong,
  • Andreas Matussek and
  • Xiangning Bai

Shiga toxin-producing Escherichia coli (STEC) can cause diseases ranging from mild diarrhea to fatal extra-intestinal hemolytic uremic syndrome (HUS). Shiga toxin (Stx) is the key virulence factor in STEC, two Stx types (Stx1 and Stx2) and several su...

Effect of Caging on Cryptosporidium parvum Proliferation in Mice

  • Hannah N. Creasey,
  • Wen Zhang and
  • Giovanni Widmer

Cryptosporidiosis is an enteric infection caused by several protozoan species in the genus Cryptosporidium (phylum Apicomplexa). Immunosuppressed mice are commonly used to model this infection. Surprisingly, for a pathogen like Cryptosporidium parvum...
