abstract = {The initial developmental stages of Contracaecum multipapillatum (von Drasche, 1882) Lucker, 1941 sensu lato were studied using eggs obtained from the uterus of female nematodes (genetically identified) found in a brown pelican Pelecanus occidentalis from Bahía de La Paz (Gulf of California, Mexico). Optical microscopy revealed a smooth or slightly rough surface to the eggs. Egg dimensions were approximately 53 x 43 μm, although when the larvae developed inside their size increased to 66 x 55 μm. Hatching and survival of the larvae was greater at 15 ºC than 24 ºC and increased salinity resulted in a slight increase in hatching but seemed to reduce survival at 24 ºC, but not at 15 ºC. The recently hatched larvae measured 261 x 16 μm within their sheath. When placed in culture medium the larvae grew within their sheath and a small percentage (~2%) exsheathed completely (314 x 19 μm). The larvae continued to grow and develop once they had exsheathed, attaining mean dimensions of 333 x 22 μm. Although they did not moult during culture, optical microscopy revealed a morphology typical of third-stage larvae. Finally, the genetic identity found between the larvae of the parasite from mullet and adult females from the brown pelican suggests a life cycle of C. multipapillatum in which the mullet are involved as intermediate/paratenic hosts and the brown pelicans as final hosts in the geographical area of Bahía de La Paz.},
