| clinically mild tularemia associated with tick-borne francisella tularensis. | between may 9 and july 3, 1979, 12 cases of glandular or ulceroglandular tularemia occurred in residents of the crow indian reservation in southcentral montana; only 13 cases had been reported from this geographic area in the preceding 25 years. the illness was mild, characterized by fever and cervical or occipital adenopathy. systemic symptoms were self-limited although residual lymphadenopathy was common. francisella tularensis was isolated from ticks (dermacentor variabilis), the suspected ve ... | 1983 | 6886487 |
| survey for selected diseases in nutria (myocastor coypus) from louisiana. | thirty-two trapper-caught nutria (myocastor coypus) from east baton rouge, iberville, tangipahoa, and st. helena parishes in louisiana (usa) were sampled for several disease agents. antibodies against toxoplasma gondii, chlamydia psittaci, francisella tularensis, leptospira spp., and encephalomyocarditis virus were detected in 7%, 14%, 0%, 7%, and 0% of nutria, respectively. both animals seropositive for leptospirae were positive for l. interrogans serovar canicola. no salmonella spp. were isola ... | 1994 | 7933295 |
| tularemia in range sheep: an overlooked syndrome? | abortion and death caused by francisella tularensis were well recognized in range flocks of domestic sheep in idaho, montana, and wyoming in the first 6 decades of the 20th century. the current report describes 4 episodes of tularemia in 3 range flocks in wyoming and south dakota in 1997 and 2007 (1 flock was affected twice). flock owners reported that ticks were unusually numerous and commonly present on sheep during outbreaks. tularemia presented as late-term abortions (3 episodes) or listless ... | 2008 | 18599860 |
| quantum differences in oral susceptibility of voles, microtus pennsylvanicus, to virulent francisella tularensis type b, in drinking water: implications to epidemiology. | shedding nephritis in voles with chronic tularemia is the probable source of frequent contamination of streams over wide areas of the northern hemisphere. however, voles inoculated parenterally with as few as one dex viable cells of francisella tularensis palaearctica succumb uniformly to acute tularemia, whereas voles, beavers, and muskrats often thrive in waters contaminated with the organism. nevertheless, water-borne epizootics do occur in these animals, and at these times streams are heavil ... | 1983 | 6381031 |
