| high divergence within the major hiv type 1 subtype b epidemic in panama. | the first molecular epidemiology study of human immunodeficiency virus type 1 (hiv-1) in panama has been performed with plasma samples from 66 aids patients infected by different transmission routes and obtained from distinct locations. all samples were amplified by rt-pcr and sequenced in gag (p17) and env (c2-c4) genes. phylogenetic analyses revealed that 64 (97%) of the samples belong to subtype b. we also identified the presence of two crf, one crf12_bf and one crf02_ag. the most notable fea ... | 2008 | 19000026 |

| human immunodeficiency virus infection in the republic of panama. | thirty-one documented acquired immune deficiency syndrome (aids) cases occurred in panama during 1984-1987. twenty-three (74%) patients were homosexual males and all but 2 patients recognized prior to june 1987 have died. to identify risk factors for human immunodeficiency virus infection, 287 male homosexual residents of panama city were enrolled in a cross-sectional study. nine had human immunodeficiency virus (hiv) antibody. travel to the united states, homosexual relations with united states ... | 1988 | 3189701 |

| [immunologic evaluation of 246 hiv patients]. | the authors report the results of the immunological studies carried out on 246 individuals infected with the human immunodeficiency virus (hiv) in order to compare these data with those obtained in a previous study. they demonstrate an appreciable increase in the number of women with hiv infection and the change of the major cause of infection, in men as well as in women, from transfusions to heterosexual relations with promiscuous and/or bisexual men. they emphasize the danger of hiv infection ... | 1991 | 1767035 |
| human t-lymphotropic virus type ii among guaymi indians--panama. | human t-lymphotropic virus type 2 (htlv-ii) is one of four retroviruses (i.e., htlv-i, human immunodeficiency virus type 1 [hiv-1], and hiv-2) that are known to infect humans. during 1988, investigators from the gorgas memorial laboratory (gml) and the national institutes of health (nih) tested serum specimens collected during 1978-1987 throughout panama to determine the prevalence of htlv-i infection (1), which is endemic in southern japan and the caribbean basin (2). htlv seropositivity rates ... | 1992 | 1549085 |
| a search for anti-viral properties in panamanian medicinal plants. the effects on hiv and its essential enzymes. | aqueous and methanolic extracts of 39 panamanian medicinal plants were tested for anti-human immunodeficiency virus (hiv) effects. the extracts were tested for the inhibition of hiv-induced cytopathic effects in cultured cells, hiv-reverse transcriptase (rt) and hiv-protease (pr) enzymes. the water extract of the branches of jatropha curcas (euphorbiaceae) inhibited strongly the hiv-induced cytopathic effects with low cytotoxicity. on the other hand, the water extracts of the whole plant of cham ... | 1999 | 10075118 |
