| diarrheagenic escherichia coli in human immunodeficiency virus (hiv) pediatric patients in lima, peru. | we conducted a prospective study in three hospitals in lima in human immunodeficiency virus (hiv) children to determine the frequency of diarrheagenic escherichia coli. five e. coli colonies/patients were studied by a multiplex real-time polymerase chain reaction to identify the six currently recognized groups of diarrhea-associated e. coli. we have analyzed 70 hiv-associated diarrheal and 70 control samples from hiv-infected children without diarrhea. among the diarrheal episodes 19% were persi ... | 2010 | 20595495 |
| phylogeny of human t cell lymphotropic virus type 1 in peru: a high degree of evolutionary relatedness with south african isolates. | we investigated the prevalence and molecular epidemiology of human t cell lymphotropic virus type 1 in peruvian hiv-1-positive subjects, and found a 10.1% prevalence in a consecutive series of 318 hiv-1-positive patients living in lima. phylogenetic analysis of the long terminal repeat of 10 patient isolates showed that all of them belonged to the htlv-1aa (transcontinental) subgroup. although the majority of the peruvian sequences included in the analysis formed a clade with other latin america ... | 2007 | 17919111 |

| distinctiveness of mycobacterium tuberculosis genotypes from human immunodeficiency virus type 1-seropositive and -seronegative patients in lima, peru. | genotypic analysis of mycobacterium tuberculosis isolates obtained from human immunodeficiency virus type 1 (hiv-1)-seropositive (n = 80) and -seronegative (n = 25) patients from lima, peru, revealed two distinct genotypes correlating with the host immune status. while the level of intrastrain diversity of dna fingerprints of hiv-seropositive isolates was less pronounced, these isolates showed many clonal groupings. | 2003 | 12682166 |
