Other claims from this paper (13)
- Observation MNSV was detected in field-grown rockmelon (Cucumis melo) plants in the Sunraysia district of New South Wales and Victoria, Australia, in 2012-2016.
- Observation MNSV was detected in field-grown watermelon (Citrullus lanatus) plants in the Sunraysia district of New South Wales and Victoria, Australia, in 2012-2016.
- Observation MNSV was detected in two watermelon seed lots tested at the Australian border in 2016.
- Observation Phylogenetic analysis suggests at least two incursions of MNSV into Australia.
- Observation None of the field isolates were the same as the MNSV isolates detected in seeds.
- Observation One watermelon field sample (L10), the Victorian rockmelon field sample and two seed interception samples may have European origins.
- Observation Isolates L8 and L9 from watermelon were divergent from the type MNSV strain.
- Observation Isolates L8 and L9 had 99% nucleotide identity to two MNSV isolates from human stool collected in the United States.
- Observation Isolates L8 and L9 had high nucleotide pairwise identity (96%) to a partial sequence from a Spanish MNSV isolate.
- Observation The analysis identified three previously described MNSV genotype groups: EU-LA, Japan melon and Japan watermelon.
- Recommendation The genotype groups EU-LA, Japan melon and Japan watermelon should be renamed to groups I, II and III.
- Observation The divergent isolates L8 and L9 and the US stool isolates formed a fourth genotype group, group IV.
- Observation Soil from the site of the Victorian rockmelon MNSV outbreak contained viable MNSV and the chytrid vector Olpidium bornovanus.
