| [sudden death of alpine cattle in the canton graubünden]. | the aetiology of sudden deaths of cattle in the kanton graubünden has been elucidated by a multi-disciplinary approach. certain small rivers and ponds located in the affected alpine pastures in the areas of misox, rheinwald and engadin provide favourable habitats for the growth of hepatotoxic cyanobacteria, particularly during long periods of hot and dry weather. as cattle frequently take up water from these sources, the toxins produced by cyanobacteria may lead to lethal poisonings that are typ ... | 1997 | 9411726 |
| concurrent infections with vector-borne pathogens associated with fatal hemolytic anemia in a cattle herd in switzerland. | bovine anaplasmosis is a vector-borne disease that results in substantial economic losses in other parts of the world but so far not in northern europe. in august 2002, a fatal disease outbreak was reported in a large dairy herd in the swiss canton of grisons. diseased animals experienced fever, anorexia, agalactia, and depression. anemia, ectoparasite infestation, and, occasionally, hemoglobinuria were observed. to determine the roles of vector-borne pathogens and to characterize the disease, b ... | 2004 | 15297529 |
| [anaplasmosis in a swiss dairy farm: an epidemiological outbreak investigation]. | in summer of 2002, a case of severe clinical bovine anaplasmosis caused great losses in a dairy farm of an animal trader in grisons. this article outlines the general approach of an outbreak investigation considering the case of anaplasmosis as an example. the goals of such investigations are to identify and eliminate the source of a disease outbreak in order to avoid additional cases. in addition, recommendations should be developed for preventing or limiting the magnitude of similar outbreaks ... | 2004 | 15526601 |
| seroprevalence of anaplasmosis among cattle in switzerland in 1998 and 2003: no evidence of an emerging disease. | anaplasma marginale infection in europe has been limited to the mediterranean and eastern countries, to austria and to very sporadic cases in switzerland. there are no reports of its occurrence in the countries north of switzerland. a severe outbreak of anaplasmosis in august 2002 in a cattle farm in the canton grisons, switzerland, north of the alps, with more than 300 cattle that had to be culled, came unexpected and gave reason to hypothesize presence of an increased yet undetected prevalence ... | 2005 | 15795079 |
| [piroplasms of ruminants in switzerland and zoonotic significance of babesia]. | piroplasms are tick-transmitted blood parasites belonging to the genera babesia and theileria. in western and southern switzerland, b. divergens, a small babesia species, has been known for a long time as a parasite of cattle. recent investigations have revealed the autochthonous occurrence of this parasite also in central and eastern switzerland. on the occasion of an outbreak of anaplasmosis in the canton of grisons, however, b. bigemina, a large babesia species, and theileria of the buffeli/s ... | 2006 | 16562726 |
| bluetongue vector species of culicoides in switzerland. | switzerland is historically recognized by the office internationale des epizooties as free from bluetongue disease (bt) because of its latitude and climate. with bluetongue virus (btv) moving north from the mediterranean, an entomological survey was conducted in switzerland in 2003 to assess the potential of the btv vectors present. a total of 39 cattle farms located in three geographical regions, the ticino region, the western region and the region of the grisons, were monitored during the vect ... | 2006 | 16874919 |
| chlamydia-related abortions in cattle from graubunden, switzerland. | in 2001, the first case of bovine chlamydial abortion was reported in canton graubunden, switzerland. in this region, chlamydophila (cp.) abortus is endemic in small ruminants. hence, we aimed to investigate the incidence of chlamydia-related abortions in cattle from graubunden. during breeding seasons of 2003-2004, formalin-fixed and paraffin-embedded placenta specimens (n = 235) from late-term abortions in cattle were analyzed by histopathology, immunohistochemistry with a chlamydiaceae-specif ... | 2006 | 16966448 |
