human leptospirosis caused by a new, antigenically unique leptospira associated with a rattus species reservoir in the peruvian amazon.as part of a prospective study of leptospirosis and biodiversity of leptospira in the peruvian amazon, a new leptospira species was isolated from humans with acute febrile illness. field trapping identified this leptospire in peridomestic rats (rattus norvegicus, six isolates; r. rattus, two isolates) obtained in urban, peri-urban, and rural areas of the iquitos region. novelty of this species was proven by serological typing, 16s ribosomal rna gene sequencing, pulsed-field gel electrophoresis, ...200818382606
detection of pathogenic leptospira spp. infections among mammals captured in the peruvian amazon basin region.to identify potential zoonotic reservoirs of pathogenic leptospires in the peruvian amazon basin, wild mammals were trapped from july 1997 to december 1998 near the city of iquitos. after extraction of nucleic acids from animal kidneys, dna of pathogenic leptospires was identified by polymerase chain reaction (pcr) assays using one of two primer sets, one amplifying a region of the 23s rrna gene, and the other amplifying a gene fragment specific for leptospira spp (g1/g2 primers). overall, 29% ( ...200011421373

diversity of bat-associated leptospira in the peruvian amazon inferred by bayesian phylogenetic analysis of 16s ribosomal dna sequences.the role of bats as potential sources of transmission to humans or as maintenance hosts of leptospires is poorly understood. we quantified the prevalence of leptospiral colonization in bats in the peruvian amazon in the vicinity of iquitos, an area of high biologic diversity. of 589 analyzed bats, culture (3 of 589) and molecular evidence (20 of 589) of leptospiral colonization was found in the kidneys, yielding an overall colonization rate of 3.4%. infection rates differed with habitat and loca ...200516282313
environmental exposure and leptospirosis, peru.human infection by leptospires has highly variable clinical manifestations, which range from subclinical infection to fulminant disease. we conducted a population-based, cross-sectional seroepidemiologic study in peru to determine potential relationships of environmental context to human exposure to leptospira and disease associated with seroconversion. three areas were studied: a flooded, urban slum in the peruvian amazon city of iquitos; rural, peri-iquitos villages; and a desert shantytown ne ...200415207052
monitoring of leptospirosis seroprevalence in a colony of captive collared peccaries (tayassu tajacu) from the peruvian amazon.leptospirosis, an endemic zoonoses, is maintained in the environment by several wildlife species in the peruvian amazon. in order to evaluate the possible role of collared peccaries (cp) in the maintenance this disease, two serological surveys of leptospirosis were performed and zootechnical parameters were monitored in a captive cp colony in an interval of 27 months. total seroprevalence changed from 100% (n=27) to 86.4% (n=22), with reactions to a diversity of serogroups of zoonotic importance ...200919000627
