| the availability of state-level data on interstate cattle movements in the united states. | knowledge about the patterns of animal movement--particularly feeder-cattle movement--within the usa is necessary in order to anticipate how diseases might be spread geographically. this study was conducted to explore the availability of interstate-level movement data which might be used to develop a more coherent national picture of interstate feeder-cattle movement. state statistical offices of the national agricultural statistics service, 1996 (nass) and departments of agriculture in all 50 s ... | 1998 | 9879593 |
| canine exposure to borrelia burgdorferi and prevalence of ixodes dammini (acari: ixodidae) on deer as a measure of lyme disease risk in the northeastern united states. | surveillance programs that identify areas where both the vector (ixodes dammini) and etiologic agent (borrelia burgdorferi) are present may identify the risk of lyme disease and its spread earlier and more accurately than do programs relying on any single method, particularly human case reports. hunter-killed deer (n = 1,204) from 22 counties in maryland, massachusetts, new hampshire, new york, and pennsylvania were examined in fall 1989 and all ectoparasites were identified. the following sprin ... | 1993 | 8433324 |

| providing linguistically appropriate services to persons with limited english proficiency: a needs and resources investigation. | increasing numbers of persons in the united states cannot speak, read, write, or understand the english language at a level that permits them to interact effectively. these limitations can hamper encounters between patients and healthcare providers, often leading to misunderstandings as to diagnosis and treatment, which in turn may result in poor patient compliance, unsatisfactory outcomes, and increased costs. a questionnaire was developed and distributed to clinical practice managers at the un ... | 2004 | 15481434 |
| real-time pcr-based assay for quantitative detection of hematodinium sp. in the blue crab callinectes sapidus. | hematodinium sp. is a parasitic dinoflagellate infecting the blue crab callinectes sapidus and other crustaceans. pcr-based assays are currently being used to identify infections in crabs that would have been undetectable by traditional microscopic examination. we therefore sought to define the limits of quantitative pcr (qpcr) detection within the context of field collection protocols. we present a qpcr assay based on the hematodinium sp. 18s rrna gene that can detect 10 copies of the gene per ... | 2009 | 19419009 |
| attitudes of maryland dentists toward aids and hepatitis patients. | a survey of dentists practicing in the state of maryland found differences between general dentists (n = 905), oral surgeons (n = 88), and periodontists (n = 89). oral surgeons were more willing to treat and had actually treated more aids patients. also, almost twice as many oral surgeons agreed with the american dental association opinion that all dentists have a professional responsibility to treat aids patients. general dentists and oral surgeons were more willing to permit an aids infected d ... | 1993 | 8329159 |
| potential oversummering and overwintering regions for the wheat stripe rust pathogen in the contiguous united states. | epidemics of wheat stripe rust, caused by puccinia striiformis f. sp. tritici (pst), are more frequent in the regions where pst can oversummer and overwinter. regions for potential oversummering and overwintering of pst were determined in the contiguous united states using a survival index (si) ranging from 0 (most unfavorable) to 10 (most favorable) developed based on long-term weather data. the pathogen can survive in cool summer in the most regions north of latitude 40°n, particularly washing ... | 2014 | 23722926 |
