vector-borne infections in cats: molecular study in barcelona area (spain).previous serological surveys have reported the presence of different organisms in cats from spain but little reports exist about the exact identity of these organisms. the purpose of the study reported here was to assess the presence of dna of several vector-borne infections in a population of cats from barcelona area. one hundred blood samples obtained from cats admitted to the uab-vth were entered into the study and classified as healthy (n=48) or unhealthy (n=52). edta-blood samples were assa ...200818079064
detection of a hepatozoon and spotted fever group rickettsia species in the common marsupial tick (ixodes tasmani) collected from wild tasmanian devils (sarcophilus harrisii), tasmania.tasmanian devils are the largest extant marsupial carnivores, confined to the australian island state of tasmania. the iconic marsupial has dramatically declined in number since the discovery of devil facial tumor disease in 1996 and efforts are being made to uncover vital information to assist in the long-term survival of the species. ticks are the main vectors of arthropod-borne disease in animals, raising the question of whether tasmanian devils may be host to arthropods capable of harboring ...200919303711
