value of desiccated swabs for streptococcal epidemiology in the field.streptococcal surveys in foreign countries or remote areas may be greatly enhanced by the use of calcium alginate swabs desiccated in sterile silica gel. delays of up to 4 weeks before return to a base laboratory are feasible, and the need for fresh media or laboratory facilities in the field may be eliminated. comparison of direct plating on crystal violet blood agar versus delayed silica gel preservation during surveys in uganda, haiti, colombia, and miami, fla., showed no significant loss of ...19734346975
[hepatobiliary fascioliasis and echinococcosis/hydatidosis in domestic animals in haiti].in haiti, hepatobiliary fascioliasis and hepatic hydatid cysts cause major economic losses among livestock. surveys show high prevalence rates for bovine distomatosis caused by fasciola hepatica (10.7% to 22.78%). among small ruminants, the prevalence of distomatosis is low (sheep: 3.2%, goats: 0.9%) although dicrocoelium dendriticum is found in 1.1% of sheep. hepatic hydatidosis is more common among pigs (5.2%) and sheep (2.1%) than among goats (0.9%) and cattle (0.3%). in the case of dogs, 21% ...200718293622
the origin of hiv-1, the aids virus.this article proposes a series of experiments to determine if cows and sheep could be used as animal models for hiv-1, the aids virus. to justify this effort, a substantial case is presented that hiv-1 is a natural recombinant of bovine leukemia virus (blv) and visna virus. this natural recombinant may have been inadvertently transferred to humans through the intensified smallpox eradication program conducted in sub-saharan africa in the late 1960s and most of the 1970s.19938289690
