Abstract
We have amplified by PCR the sequences of the 5 S ribosomal spacer of Setaria labiatopapillosa and Foleyella furcata. After sequencing, these sequences have been compared with those of Dirofilaria immitis and Dirofilaria repens. Two major goals have been achieved: (i) the establishment of a multiplex PCR-based diagnostic assay, applicable to identify the four species in vertebrate and invertebrate hosts; (ii) the identification, in S. labiatopapillosa and F. furcata, of a canonical spliced leader 1 (SL1) sequence, so confirming that only D. repens, of the filarial parasites so far studied, shows a peculiar SL1 sequence. The PCR assay here developed and the analysis of the 5 S ribosomal spacer, can further improve both epidemiological and molecular analysis of these filarial species.
