| repetitive sequences in the its1 region of the ribosomal dna of tunga penetrans and other flea species (insecta, siphonaptera). | different tunga penetrans isolates from various hosts obtained from south america (fortaleza. brazil) have been studied by nucleotide sequence comparison of the first and the second internal transcribed spacer (its1, its2) of the ribosomal deoxyribonucleic acid (rdna) and part of the mitochondrial 16s rdna. results show no significant host-dependent sequence differences. no indication for intraindividual and intraspecific polymorphisms could be detected. comparing the its1 spacer region of t. pe ... | 2008 | 17952470 |
