    Notes: Samples of Neocyttus rhomboidalis from eight areas off southern Australia and eastern New Zealand were examined to assess the stock structure of the species. No spatial heterogeneity was detected for mitochondrial DNA variation after restriction analysis by two enzymes detecting polymorphic cut sites. Twenty mtDNA haplotypes were recorded, with an overall haplotype diversity of 0·683. Twenty-eight allozyme loci were examined; the mean heterozygosity per locus was 13·0%. Significant sample heterogeneity was detected at three of twelve polymorphic loci: MPI*, PGM-1* and, most strikingly (GST=0·43), sSOD*. Most of the sSOD* differentiation was associated with depth rather than geographical separation; sSOD* allele frequencies of shallow and deep samples being very different. It is suggested that the correlation between the sSOD* allele frequencies and depth is more likely to reflect natural selection than reproductive isolation. The spatial patterning of the MPI* and PGM-1* data suggest there are at least three geographic stocks of N. rhomboidalis in Australasian waters: (1) New Zealand, (2) Western Australia and South Australia, (3) west Tasmania to New South Wales and Lord Howe Rise.

    Notes: Abstract The monoclonal antibody LA7 was raised against the species-specific Borrelia burgdorferi lipoprotein P22 (= IPLA7), which induces antibody formation in patients with Lyme arthritis. It is composed of 194 amino acids with a calculated molecular mass of 21.8 kDa. Its gene on the linear chromosome is 582 nucleotides in length. The aim of this study was to localize the protein P22 by immune electron microscopy. Immunolabeling of Borrelia burgdorferi with LA7 and an anti-mouse immunogold conjugate proved that P22 is an outer membrane protein. This finding was confirmed by sodium dodecyl sulfate polyacrylamide gel electrophoresis of the outer envelope fraction, which contained 99% of the P22 proteins.
