We report here the complete genome sequence of the widely studied Actinobacillus pleuropneumoniae serovar 8 reference strain 405, generated using the Pacific Biosciences (PacBio) RS II platform. Furthermore, we compared draft sequences generated by Illumina sequencing of six stocks of this strain, including the same original stock used to generate the PacBio sequence, held in different countries and found little genetic variation, with only three SNPs identified, all within the degS gene. However, sequences of two small plasmids, pARD3079 and p405tetH, detected by Illumina sequencing of the draft genomes were not identified in the PacBio sequence of the reference strain.

Genetic variation within and between fifteen closed broodstock lines of the Pacific white shrimp Litopenaeus vannamei, reared at different hatcheries in the Brazilian coast, was assessed by RAPD analysis. Fifty two polymorphic loci were identified when a set of five decamer primers was used in PCR. The genetic diversity analysis within lines evidenced genetic variation loss probably related to bottleneck effects and inbreeding. In addition, the genetic divergence values between the different samples appear to reflect the initial founder composition of such stocks, in some cases, sharing a common origin, suggesting a putative importance of interbreeding for the establishment of genetic improvement programs for these broodstocks. The genetic variation monitoring appears to be helpful to the gene pool conservation of this aquaculture species, mainly if considered its exotic status in Brazil and the current impossibility of new introduction of wild individuals.

Genetic variation, exhibited by electrophoretic analysis of tissue proteins and enzymes, of the Pacific oyster (Crassostrea gigas) was analyzed. Eleven systems were examined, reflecting 15 loci of which 8 were polymorphic and 7 were monomorphic. The number of alleles per locus varied from 1 at four loci (Aat-1, Mdh-1, Me, and To-1) without allelic variation, to 6 at the Pgm locus. The average number of alleles per locus was 2.7, while the effective number of alleles was calculated to be 1.3. An individual was found to be heterozygous, on the average, at 21% of the loci. Allelic variation was found at 11 out of 15, or 73% of the loci. At 53% of the loci the frequency of the most common allele was no greater than 0.95.
