the relationship of haitian small farm management to goat and cattle diseases.a 40 week study of 43 farmers, 60 goats and 60 cattle was conducted in order to identify abnormal conditions or diseases and predisposing seasonal, managemental or nutritional factors. farms were visited, farmers interviewed and animals examined up to 4 times, about every 10 weeks and bled for ht, total wbc, selected serum vitamins and minerals hair collected for mineral analysis. soil and forages were collected for analysis. there were serious soil, forage and animal phosphorus and lesser vitam ...19938134655
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

survey for cyclospora cayetanensis in domestic animals in an endemic area in haiti.from january 1997 through july 1998, we examined stool samples from 327 domestic animals, including pigs, cattle, horses, goats, dogs, cats, guinea pigs, chicken, ducks, turkeys, and pigeons in leogane, haiti, for the presence of cyclospora cayetanensis infection. no coccidian oocysts morphologically compatible with c. cayetanensis were detected in any of the animal samples, despite their living in, or near, households with infected individuals. these results suggest that domestic animals are no ...199910386455

cutaneous anthrax in the artibonite valley of haiti: 1992-2002.more cutaneous anthrax cases were noted at hospital albert schweitzer (has) in the artibonite valley of haiti. we examine the incidence of anthrax in the artibonite between 1992 and 2002, describe the clinical presentation of cutaneous anthrax, and determine risk factors for anthrax. in 1992 has reported 1 case of anthrax for an incidence of 4 cases per million persons/year. in 2002, there were 20 cases of anthrax for an incidence of 72 cases per million persons/year. this is a 17-fold increase ...200717984330
epidemic anthrax in the eighteenth century, the americas.anthrax has been described as a veterinary disease of minor importance to clinical medicine, causing occasional occupational infections in single cases or clusters. its potential for rapid and widespread epidemic transmission under natural circumstances has not been widely appreciated. a little-known 1770 epidemic that killed 15,000 people in saint-domingue (modern haiti) was probably intestinal anthrax. the epidemic spread rapidly throughout the colony in association with consumption of uncooke ...200212396933
human t and b cell immunoreactivity to a recombinant 23-kda cryptosporidium parvum antigen.cryptosporidial infection in humans results in parasite-specific igg, igm, and iga antibody responses, but little is known of the cell-mediated immune responses to cryptosporidial antigens. in a convenience sample of 35 haitian residents, there was a high level of cryptosporidial exposure (>90%) as determined by immunoblot reactivity of serum against cryptosporidial antigens. an attempt was made to determine if there was a relationship between antibody and t cell-mediated responses to recombinan ...200111426740
[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
