A collection of nematodes from the Muséum National d’Histoire Naturelle (National Museum of Natural History), Paris, France, was studied. The nematodes had previously been collected from a range of marine fish hosts. The aim of this study was to investigate the identity of these nematodes. Detailed body measurements of the nematodes were taken via light microscopy and where possible first and second internal transcribed spacers (ITS-1 and ITS-2) of ribosomal DNA were subjected to PCR, purified and sequenced. Six species and three larval types were found from a range of fish species and included 13 new host records and two new geographical records. Of the taxa found, Hysterothylacium kajikiae is the only species which may have zoonotic potential. The majority of host fish in this study are edible species, commercially and recreationally fished and frequently incorporated into the cuisine of New Caledonia as raw fish dishes. This study will allow better understanding of the diversity, life cycles, distribution and host-parasite relationships in the New Caledonia area.

研究了法国巴黎国立自然历史博物馆（国家自然历史博物馆）的线虫。线虫以前是从一系列海洋鱼类宿主中收集的。这项研究的目的是调查这些线虫的身份。通过光学显微镜对线虫进行详细的身体测量，并在可能的情况下对核糖体DNA的第一和第二内部转录间隔子（ITS-1和ITS-2）进行PCR，纯化和测序。从一系列鱼类中发现了6种和3种幼虫类型，其中包括13个新的寄主记录和2个新的地理记录。在发现的分类单元中，卡奇氏菌是唯一可能具有人畜共患病潜力的物种。在这项研究中，大多数寄主鱼类是可食用的种类，商业和休闲捕鱼，并经常作为生鱼料理并入新喀里多尼亚的美食中。这项研究将使人们更好地了解新喀里多尼亚地区的多样性，生命周期，分布以及寄主与寄生虫之间的关系。
