RESUMO
The development of a comprehensive data base for hospital-based ambulatory care has made possible the accurate determination of each community's use of hospitals in New York City and permits a reliable estimation of all ambulatory care received by residents of Health Manpower Shortage Areas (HMSAs). In spite of the city's abundant supply of private practitioners and widespread Medicaid coverage, residents of HMSAs in New York City are heavily dependent on hospital-based ambulatory care. Contrary to commonly held notions, however, HMSA residents do not appear to overuse hospital-based ambulatory care. Rather, that use appears to be quite modest, given their poorer health status.

High molecular weight DNA obtained from sheep parasitic nematodes Haemonchus contortus, Ostertagia circumcincta and Trichostrongylus colubriformis, was digested with various restriction endonucleases. Digestion with Eco R1 produced the most informative pattern of repeat sequence bands. H contortus adult or larval DNA produced bands of 2.7, 3.0 and 1.4 kb. O circumcincta adult or larval DNA had common 2.7 and 1.4 kb bands with adult specific bands of 2.2 and 0.9 kb and a larval specific 2.08 kb band. T colubriformis adults or larval DNA produced 2.7, 1.4 and 0.79 kb bands. These preliminary results show that restriction patterns of repeat sequence DNA may be useful for the identification of various trichostrongylid species parasitic for sheep.
