cycles in voles and small game in relation to variations in plant production indices in northern sweden.population dynamics for voles (cricetidae), tengmalm's owl (aegolius funereus (l.)), red fox (vulpes vulpes (l.)) willow grouse (lagopus lagopus (l.)), black grouse (lyrurus tetrix (l.)), capercaillie (tetrao urogallus l.), hazel hen (tetrastes bonasia (l.)), mountain hare (lepus timidus l.) and tularemia (francisella tularensis (mccoy & chapin)) and game bird recruitment were studied by index methods in northern sweden. in addition contemporary temperature records and spruce (picea abies (l.) k ...198628311702
tularaemia in norwegian dogs.we describe tularaemia in a norwegian dog caused by francisella tularensis subspecies holarctica. a hamilton hound and his owner developed tulaeremia after hunting an infected mountain hare (lepus timidus). the dog showed signs of lethargy, anorexia and fever during a period two to four days after hunting and thereafter fully recovered. its antibody titers increased 32-fold from one to three weeks post exposure. thereafter, the titer declined and leveled off at moderate positive values up to one ...201425150161
a serological survey of antibodies against francisella tularensis in some swedish mammals.tularemia occurs in sweden as an epizootic among the mountain hare. little is known about the occurrence of the disease in other animals in this country. for this reason serum samples from 28 cattle, 83 moose, 110 beavers and 97 mountain hares were investigated for the presence of antibodies against francisella tularensis. the antibody levels against f. tularensis found in moose and cattle were generally low and also in a low incidence. this indicates that these species are not susceptible to tu ...19836878028
an endemic case of tularemia in the mountain hare (lepus timidus) on the island of stora karlsö.in september 1983, an epizootic of unknown cause broke out among the mountain hares on the island of stora karlsö, which is located outside the coast of gotland. one hare was sent in the national veterinary institute for post-mortem examination. the hare showed lesions in liver, spleen, and bone-marrow typical for tularemia. the specimens were positive for francisella tularensis with fluorescent-antibody test. tularemia has not been observed earlier in this part of sweden. it is supposed that th ...19846393050
infections with francisella tularensis biovar palaearctica in hares (lepus timidus, lepus europaeus) from sweden.the occurrence of tularemia was studied in 1,500 hares submitted to the national veterinary institute, uppsala, sweden for postmortem examination during 1973 through 1985. a total of 109 tularemia cases was recorded based on the fluorescent antibody (fa) test for francisella tularensis and on the gross and microscopic pathology. tularemia was diagnosed only in the varying hare (lepus timidus) and not in the european brown hare (lepus europaeus). the geographical distribution of the 109 cases ind ...19882900904
identification and classification of different isolates of francisella tularensis.the causative agent of tularemia, francisella tularensis, occurs in two main biovars, the highly virulent f. t. biovar tularensis, found in north america; and the less virulent biovar palaearctica, found all over the northern hemisphere. two other biovars have been proposed, f. t. biovar mediaasiatica and f. t. biovar palaearctica var. japonica. in sweden tularemia is most frequently observed in man and varying hares (lepus timidus), and occasionally in other species. tularemia in hares is norma ...19937510445
