title: Temporal fluctuation of infection with different Trypanosoma cruzi genotypes in the wild rodent Octodon degus.
abstract: We identified and followed-up for two years Octodon degus rodents infected with Trypanosoma cruzi genotypes by using xenodiagnosis with two vector species (Mepraia spinolai and Triatoma infestans), polymerase chain reaction DNA-based detection of insect dejections, Southern blot analysis, and minicircle hybridization with genotype-specific probes. Results show temporal fluctuations of infection with four parasite lineages (TCI, TCII, TCV, and TCVI) in one co-infected O. degus. Results are discussed in the context of parasitemia level and infection control in mammal hosts.
