> the difference between N. apis, N. ceranae, N. bombi, N. bombycis, etc
These different Nosema species were named after the organisms in which they were discovered: the European honey bee, the Asian honey bee, bumble bees, and silkworms, respectively. It is now known that some of these are cross infective and may be contributing to the decline of native pollinators. The actual distinctions have to be made using advanced dna sequencing techniques.
QUOTED MATERIAL:
Genome sequencing of N. apis and comparative genome analysis with N. ceranae, a fully sequenced microsporidia species,
reveal novel insights into host-parasite interactions underlying the parasite infections.
We applied the whole-genome shotgun sequencing approach to sequence and assemble the genome of
N. apis which has an estimated size of 8.5 Mbp. We predicted 2,771 protein- coding genes and predicted the
function of each putative protein using the Gene Ontology. The comparative genomic analysis led to identification
of 1,356 orthologs that are conserved between the two Nosema species and genes that are unique characteristics
of the individual species, thereby providing a list of virulence factors and new genetic tools for studying host-parasite
interactions.
The availability of the N. apis genome sequence is a significant addition to the rapidly expanding
body of microsprodian genomic data which has been improving our understanding of eukaryotic genome diversity
and evolution in a broad sense.
Although they share some morphological, biological and genetic features, as well as invasive strategies,
the genome sequences of N. apis and N. ceranae revealed that these microsporidia species are highly diversified.
