A recombinant cDNA probe from genome segment 5 obtained from a virulent US bluetongue virus strain (BTV-11 strain UC8) was hybridized to US and Israeli BTV prototypes and field isolates. The cloned genetic probe hybridized with US BTV prototype 10, but not with US prototypes 2, 11, 13, and 17; with the avirulent BTV-11 strain UC2; and with the Israeli prototype 10. When the probe was hybridized to field isolates from the US serotypes, it hybridized to 12 of 14 BTV-10 isolates and 4 of 17 BTV-11 samples, but not to the BTV-13 and BTV-17 samples tested. Hybridization was not observed with the Israeli field isolates studied. Results indicate that a reassortant event occurred between a strain of US BTV-10 and US BTV-11 that originated the BTV-11 strain UC8. 相似文献

An infection with Histoplasma capsulatum was diagnosed in two wild badgers (Meles meles) in northern Germany, which was predominantly localized in the skin and the regional lymph nodes. The yeast-like fungi were identified in tissue sections using histological and immunohistological methods. 相似文献

A ferret with clinical and laboratory signs of hypoglycemia was found at surgery to have a beta cell tumor of the pancreas. There had been recurrent episodes of weakness, ataxia, dehydration, and hypothermia. A fasting blood glucose content was 43 mg/dl and the amended insulin/glucose ratio was 362.5. The tumor was removed, yet hypoglycemia persisted postoperatively. Clinical signs related to hypoglycemia did not recur following application of medical treatment and frequent feedings. The histologic appearance of the tumor closely resembles that which has been seen in other species. 相似文献

SUMMARY Lice were collected from 71 flocks detected as Infested at market Inspection in 1990 and 1991, from 16 flocks where resistance was suspected and from 31 flocks from Kangaroo Island. Susceptibility to cypermethrin was measured by a treated surface technique and survival of lice at 5 ppm or greater was taken as an indication of resistance. The prevalence of resistance was 34% in louse populations from the market inspection sample, 50% in flocks in which resistance was suspected and 68% in flocks from Kangaroo Island. Most resistance factors were in the range 1 to 20 although one louse population with a resistance factor of 91 was found on Kangaroo Island. 相似文献

BACKGROUND: Ovariectomized sheep are a useful model of postmenopausal osteoporosis and other postmenopausal conditions. Estrogen may have a protective effect on the coronary arteries in postmenopausal women. The effects of raloxifene, a selective estrogen receptor modulator, on coronary arteries in aged ovariectomized ewes was investigated. METHODS AND RESULTS: Forty eight aged ewes were randomly assigned to undergo sham surgery (Sham, n = 7), ovariectomy (OVX, n = 10), ovariectomy with estradiol supplementation (OVXE, n = 8), ovariectomy with raloxifene supplementation, 0.02 mg/kg per day (RAL1, n = 10), or ovariectomy with raloxifene supplementation, 0.10 mg/kg per day (RAL2, n = 13). Contrast coronary angiography was performed 6 months after intervention. Diameters of the right main and left anterior descending coronary arteries in the RAL1, RAL2 and Sham groups were not different from each other, but were significantly greater than the OVX and OVXE groups. Intracoronary nitroglycerin did not affect the relationships of the diameters in any group. There were no differences in vascular remodeling between the groups. CONCLUSIONS: The results indicate that raloxifene in this sheep model allows greater dilation of coronary arteries than estrogen. Raloxifene may provide a significant protective functional effect on coronary arteries in postmenopausal heart disease. 相似文献

The distribution and environmental disequilibrium patterns of naturally occurring uranium isotopes (U(234) and U(238)) in waters of the Floridan aquifer suggest that variations in the ratios of isotopic activity and concentrations can be used quantitatively to evaluate mixing proportions of waters from differing sources. Uranium is probably unique in its potential for this approach, which seems to have general usefulness in hydrologic investigations. 相似文献

An adult female nine-banded armadillo (Dasypus novemcinctus) died in the quarantine station of a private Swiss zoo. Multifocal ulcerative skin lesions and multiple hemorrhages in the lungs were found at necropsy. The spleen was enlarged and dark red. Histologically, there was diffuse granulomatous infiltration, including multinucleated giant cells, of the skin lesions, lungs, spleen, liver, heart, and kidneys. Abundant periodic acid-Schiff-positive yeastlike cells were demonstrated intracellularly in giant cells and extracellularly scattered throughout the tissues. Morphology of the cells varied, with some nonbudding cells resembling Cryptococcus neoformans and others resembling Sporothrix schenckii. A diagnosis of sporotrichosis was confirmed by immunofluorescence studies. This is the first report of sporotrichosis in an armadillo in a zoological garden and the third report of sporotrichosis in D. novemcinctus. 相似文献
