serologic prevalence of toxoplasmosis in cattle, sheep, goats, pigs, bison, and elk in montana.serum samples from 2,539 cattle, 649 sheep, 123 goats, 413 pigs, 93 bison, and 56 elk from montana were examined for antibody to toxoplasma gondii in the sabin-feldman dye test or the modified agglutination test (mat). cattle, bison, and elk serum samples were treated with 0.2 m-mercaptoethanol before examination in mat. in the dye test, 13.2% of sheep, 5.0% of pigs, and 22.7% of goats had antibody at a dilution of greater than or equal to 1:16. in the mat, 3.2% of cattle, 3.1% of bison, and non ...19853997650

coyote as a final host for sarcocystis species of goats, sheep, cattle, elk, bison, and moose in montana.tissues (1 kg) from sheep, goats, cattle, moose, bison, or elk naturally infected with sarcocystis species were fed to one to four sarcocystis-free coyotes and the number of sporocysts in feces and intestines were counted. all 12 coyotes fed naturally infected tissues shed sarcocystis in feces, with a prepatent period of 9 to 15 days. the four coyotes fed infected beef had 15, 25, 113, and 201 million sporocysts in their feces and intestines. the coyotes fed elk, moose, or bison had 2.5, 15, and ...19806778270
epizootic toxoplasmosis associated with abortion in dairy goats in montana.perinatal toxoplasmosis was diagnosed in goats from 2 farms in montana. of 7 pregnant does from one farm, 1 aborted a dead fetus and 2 each had a kid infected in utero. toxoplasma gondii was demonstrated histologically in the placenta of 2 of the infected does and by mouse inoculation in all 3 of them. the organism also was isolated from internal organs of 6 of 7 does, 4 of 4 cats, and 3 of 11 chickens from the farm. a pregnant doe from the other farm delivered 3 kids infected with t gondii. one ...19817204243
enteric coccidia of cashmere goats in southwestern montana, usa.a survey of enteric coccidia was made in a cashmere goat herd in montana, usa. eimerian oocysts were found in 97.2% of 616 fecal samples. newly weaned wethers and does had higher oocyst counts than yearling wethers. nine eimeria species were identified, with eimeria arloingi, eimeria ninakohlyakimovae and eimeria alijevi jointly comprising 88.3% of all oocysts recovered. these three species and eimeria hirci were present in all specimens examined. prevalence of the other species was as follows: ...19947886912
seasonal transmission of fasciola hepatica in montana, usa, with detection of infected intermediate hosts using a dna-based assay.a cashmere goat ranch in the beaverhead valley, southwest montana, usa reported acute fasciolosis in march 1992. the ranch was used as a study site to gather seasonal transmission data for the liver fluke, fasciola hepatica. testing of snails for infection with a nucleic acid-based assay, and use of tracer sheep at the site has shown the seasonal transmission of the parasite is only in late autumn. the snail responsible for transmission was identified as lymnaea modicella although another known ...19968983156
sequence analysis of the msp4 gene of anaplasma ovis strains.anaplasma ovis (rickettsiales: anaplasmataceae) is a tick-borne pathogen of sheep, goats and wild ruminants. the genetic diversity of a. ovis strains has not been well characterized due to the lack of sequence information. in this study, we evaluated bighorn sheep (ovis canadensis) and mule deer (odocoileus hemionus) from montana for infection with a. ovis by serology and sequence analysis of the msp4 gene. antibodies to anaplasma spp. were detected in 37% and 39% of bighorn sheep and mule deer ...200717052866
echinococcus granulosus in gray wolves and ungulates in idaho and montana, usa.we evaluated the small intestines of 123 gray wolves (canis lupus) that were collected from idaho, usa (n=63), and montana, usa (n=60), between 2006 and 2008 for the tapeworm echinococcus granulosus. the tapeworm was detected in 39 of 63 wolves (62%) in idaho, usa, and 38 of 60 wolves (63%) in montana, usa. the detection of thousands of tapeworms per wolf was a common finding. in idaho, usa, hydatid cysts, the intermediate form of e. granulosus, were detected in elk (cervus elaphus), mule deer ( ...200919901399
plastid dna diversity is higher in the island endemic guadalupe cypress than in the continental tecate cypress.callitropsis guadalupensis (guadalupe cypress) is endemic to guadalupe island, mexico, where it is the dominant species of the only forest. the species has suffered declining numbers following the introduction of goats to the island over 150 years ago. callitropsis guadalupensis is closely related to callitropsis forbesii (tecate cypress), distributed in small isolated populations in mainland baja california and southern california. the objective of the present study was to compare the genetic d ...201121283771
Notes from the field: Q fever outbreak associated with goat farms--Washington and Montana, 2011.On April 22, 2011, the Q fever bacterium Coxiella burnetii was detected in a goat placenta collected from a farm in Washington, where 14 of 50 (28%) pregnant does had aborted since January. A county health alert advised health-care providers to ask patients with symptoms compatible with Q fever (e.g., fever, headache, chills, and myalgia) about exposure to goats, and the owners of the farm informed purchasers of their goats that C. burnetii had been detected in their herd. On May 25, the county ...201121993345
