| [frequency of hiv-1, rubella, syphilis, toxoplasmosis, cytomegalovirus, simple herpes virus, hepatitis b, hepatitis c, chagas disease and htlv i/ii infection in pregnant women of state of mato grosso do sul]. | it was aimed to estimate the frequency of syphilis, rubella, hepatitis b, hepatitis c, toxoplasmosis, chagas disease, htlv i/ii, simple herpes virus, hiv-1 and cytomegalovirus in pregnant women and to evaluate the relationship between age and the frequency of the infections studied. a transversal study of 32,512 pregnant women submitted to pre-natal screening in the period of november 2002 to october 2003. the frequency of the tried infections among the pregnant women were 0.2% of hiv-1, 0.03% o ... | 2007 | 17568885 |
| tracing the origin of brazilian htlv-1 as determined by analysis of host and viral genes. | we compared the genetic diversity of the brazilian human t-cell lymphotropic virus type 1 isolates with those found in kwazulu-natal (kzn), south africa, and with the genetic background of the hosts. the seroprevalence rate in kzn was 1.7%. all sequences belonged to the a subgroup. the presence of south african sequences in two different clusters from brazil, and the finding of the beta-globin haplotype in infected hosts are consistent with the transmission of this virus from southern africa to ... | 2006 | 16514313 |
