Abstract: Helminth parasites of vertebrates have been studied in Costa Rica for more than 50 years. Survey work on this group of parasites is far from complete. We assembled a database with all the records of helminth parasites of wild and domestic vertebrates in Costa Rica. Information was obtained from different sources such as literature search (all published accounts) and parasite collections. Here we present a checklist with a parasite- host list as well as a host-parasite list. Up to now, 303 species have been recorded, including 81 species of dige- neans, 23 monogeneans, 63 cestodes, 12 acanthocephalans, and 124 nematodes. In total, 108 species of verte- brates have been studied for helminths in Costa Rica (31 species of fishes, 7 amphibians, 14 reptiles, 20 birds, and 36 mammals). This represents only 3.8% of the vertebrate fauna of Costa Rica since about 2,855 species of vertebrates occur in the country. Interestingly, 58 species (19.1 %) were recorded as new species from Costa Rica and most of them are endemic to particular regions. Considering the valuable information that parasites provide because it is synergistic with all the information about the natural history of the hosts, helminth parasites of ver- tebrates in Costa Rica should be considered within any initiatives to accomplish the national inventory of bio- logical resources. Starting with this compilation work, the Colección de Helmintos de Costa Rica (CHCR), host- ed at the Facultad de Microbiología, Universidad de Costa Rica, has re-emerged and it is our hope that it will have the standards of quality to assure that it will become the national depository of helminths in the country. Key Words: Helminths, Costa Rica, Biodiversity, Biological inventories, Parasites, Vertebrates. Costa Rica possesses a strong tradition in (UNAM) to contribute to the understanding of the study of parasites of domestic and wildlife the Costa Rican helminth parasite biodiversity vertebrates.

The aim of this study was to identify intestinal parasites from wild rodents in Santo Amaro da Imperatriz and Santa Catariana Island, and to compare the richness and composition of the gastrointestinal parasite community of both areas. Rodents were captured with live traps, and feces were screened using the sedimentation method and optical microscopy. The following species of rodents were captured in the two areas: Akodon montensis, Euryoryzomys russatus, Oligoryzomys nigripes and Nectomys squamipes. In Santo Amaro da Impetratriz, prevalent parasites were: A. montensis (51%), E. russatus (62%), O. nigripes (53%) and N. squamipes (20%). From the Island of Santa Catarina the rodent prevalence rates were: A. montensis (43%), E. russatus (59%), O. nigripes (30%) and N. squamipes (33%) and the collected parasites were: Hymenolepis sp., Longistriata sp., Strongyloides sp., Hassalstrongylus sp., Syphacia sp., Trichomonas sp., Ancylostomidae, Trichuridae, Oxyuridae and Eucoccidiorida.

Abstract: A new species of green, prehensile-tailed pitviper of the genus Bothriechis is described from the Atlantic slopes of eastern Guatemala and western Honduras. This species appears to be most closely related to B. bicolor of the Pacific versant of Chiapas (Mexico) and Guatemala. Several other species of Bothriechis occur on the Atlantic versant of northern Central America, including two montane species, B. aurifer and B. marchi but, with one possible exception, these are not known to be sympatric with the new species and occur in differ- ent mountain ranges. The widespread B. schlegelii occurs up to at least 900 m on the Sierra de Caral, where the lowest elevation recorded for the new species is 885 m. Key words: Reptilia, Squamata, Viperidae, Pitvipers, Bothriechis, New species, Izabal, Guatemala, Honduras. Species of the arboreal pitviper genus pitvipers that are usually mostly greenish in Bothriechis range from the highlands immedi- color, have the middle preocular and suprala- ately east of the Isthmus of Tehuantepec to cunal coalesced into a single scale, and have western Panama, with one species extending an exceptionally short tail spine that is usual- into northern South America (Crother et al.

  • Recent Progress in Our Knowledge of Parasitic Worms and Their Relation to the Public Health
    378 RECENT PROGRESS IN OUR KNOWLEDGE OF PARASITIC WORMS AND THEIR RELATION TO THE PUBLIC HEALTH. BY WILLIAM NICOLL, M.A., D.Sc, M.D., D.P.H. (London School of Tropical Medicine.) TEN years ago I made an attempt to summarize briefly the advances which had been made in our knowledge of parasitic worms during the preceding few years. The interval has witnessed much upheaval and interruption of scientific labour, but nevertheless a very considerable amount of work on the subject has been accomplished. The nature of this does not appear to have been influenced to any exceptional extent by the war. During this period a terse but useful summary of the more outstanding recent parasitological work has been published by Faust who deals with the subject mainly from its zoological aspect; while the chief publications of medical interest have been succinctly reviewed by Leiper. In the following notes I propose to deal with the subject in somewhat greater detail particu- larly in its relation to the public health. One might have anticipated that in a country such as France the pre- paration and publication of scientific papers would have been grievously hampered by war conditions but that was certainly far from being the case, for French workers, indeed, are excelled only by British and Americans in the quantity and quality of their output of helminthological literature. Russia and Germany are, as might have been expected, a considerable dis- tance behind, while the only other countries in which any outstanding work on parasitic worms has been done are Brazil and Japan.
