    Notes: Abstract Polynesians have lower heterozygosities at minisatellite VNTR (Variable Number of Tandem Repeat) loci than have Melanesians; this has been taken as evidence of population-size bottlenecks during the colonisation of Polynesia. We have analysed the allelic distribution of several minisatellite loci in the population of Rapa, a Polynesian island that is known to have undergone a demographic reduction of approximately 95% since first contact with European explorers 200 years ago, leaving a surviving population of 120. We found that the minisatellite diversity of this population does not differ significantly from that of other Polynesian populations, and appears consistent with the neutral expectation of diversity assuming the infinite alleles model. This suggests that the demographic crisis that Rapa underwent did not perturb the allele distribution to the extent that the tests used here could detect. Thus we cannot say that a demographic change of this magnitude constitutes a genetic bottleneck detectable at these loci. The reduced diversity seen in Polynesia must therefore be explained either by more severe bottlenecks as might be expected during colonisation, or else by other causes.

    Seroepidemiological survey of HTLV-I infection in French Polynesia, Cook Islands and Fiji (1993)
    Springer
    European journal of epidemiology 9 (1993), S. 347-350

    Notes: Abstract Different population groups of French Polynesia, Cook Islands and Fiji were screened for Human T-Lymphotropic Virus type I (HTLV-I) antibodies. Among 1487 individuals sampled in French Polynesia, twelve were considered Western Blot (WB) indeterminate and one was considered WB-positive for HTLV-I infection. This positive subject originated from France and was a blood donor. Out of 196 Polynesians of the Cook Islands, one was WB-indeterminate. Among populations sampled in Fiji, one of 222 Melanesians was found WB-indeterminate and one of 211 Indians was WB-indeterminate.

    Immunotypes ofChlamydia trachomatis isolated from genital tract specimens in Tahiti (1994)
    Springer
    European journal of clinical microbiology & infectious diseases 13 (1994), S. 436-438

    Notes: Abstract The distribution ofChlamydia trachomatis immunotypes (serovars) in Tahiti was studied by immunotyping of local isolates using monoclonal antibodies in the micro-immunofluorescence test. From 115 isolates obtained from the genital tracts of patients attending a sexually transmitted diseases clinic and other gynecological consultations, eight immunotypes were identified: E (51.3 %), F (16.5 %), G (13 %), H (5.2 %), J (6.9 %), D (3.5 %), K (1.7 %) and I (0.9 %). In addition, an isolate with mixed immunotypes, EJ (0.9 %), was observed. This distribution was compared with those in different geographical areas.
