First report of a field outbreak of the oriental eye-fluke, Philophthalmus gralli (Mathis & Leger 1910), in commercially reared ostriches (Struthio camelus) in Zimbabwe.

A total of 17 commercially reared ostriches (Struthio camelus) from Msengi farm, Chinhoyi, Zimbabwe, observed with swollen eyes, severe conjunctivitis and constant lacrimation accompanied by a purulent exudate, were restrained for further clinical examination. Some of the birds were semi-blind with severe loss of body condition. When examined, tiny organisms were observed attached to the nictitating membranes and the conjuctival sacs of both eyes. The organisms were identified as Philophthalmus gralli, the "oriental eye-fluke" and Melanoides tuberculata, a prosobranch snail, was confirmed as the intermediate host through natural and experimental infection. To the best of our knowledge this is the first record of the oriental eye-fluke infection in birds in Zimbabwe and Africa and extends its known geographical range.

Research needs and priorities for swine internal parasites in the United States.

The swine industry in the United States is increasing in the Southeast. The proportion of pigs raised in confinement has increased to 25% and the trend is expected to continue. Changes in geographic origin and in management have affected the swine parasite fauna. A few parasites have almost disappeared and others have gained new prominence. Prevention and control of parasites are accomplished by feed additives and routine therapeutic treatments. Knowledge of the epizootiologic factors governing parasite transmission, in relation to climate and management systems, may lead to improvements in the prevention and control of swine parasites. Opportunities exist for developing biological, chemical, and managerial practices that can be integrated economically into management systems to control parasites and improve performance through decreases in mortality and morbidity and increases in daily gain and feed conversion efficiency.

Some Platyhelminths inhabiting white-throated sparrows, Zonotrichia albicollis (Aves: Emberizidae: Emberizinae), from Algonquin Park, Ontario, Canada.

Twenty-two of 26 white-throated sparrows, Zonotrichia albicollis, from Algonquin Park, Ontario, Canada, hosted 1 or 2 species of platyhelminths. One species of cestode and 3 of digeneans were collected. Anonchotaenia quiscali inhabited 50% of the sparrows. This is the third report of A. quiscali; Z. albicollis is a new host. Brachylecithum nanum inhabited 43%, Zonorchis alveyi 15%, and Prosthogonimus macrorchis 8% of the sparrows examined. Ontario is a new geographic distribution record from all 4 parasite species. The proportion of hosts infected with 2 species was not significantly different from expected based on single species prevalences, indicating that there is no competitive interaction among these species of parasites for access to the avian hosts.

Helminths of wild ruminants introduced into Czechoslovakia.

The paper contains results of helminthological studies on ruminants introduced into Czechoslovakia from other regions and continents. It is pointed out that introduction of wild ruminants is not only of theoretical importance in the adaptation of parasites to a new environment, but also of practical consequence in the mutual exchange of parasites between the imported and autochthonous game animals.

Gastrointestinal helminths in the river otter (Lutra canadensis) in Tennessee.

The first records of 3 helminth parasites from otters, Lutra canadensis, collected in Tennessee are reported. Digestive tracts of 91 river otters collected from 1983 to 1993 were examined for helminth parasites. Thirty otters were infected with Baschkirovitrema incrassatum, 5 otters were infected with Acanthocephalus sp., and 1 otter was infected with 2 Strongyloides lutrae. No significant differences in prevalence, mean abundance, or mean intensity of B. incrassatum occurred between counties or months. No significant differences in the prevalence or mean intensity of B. incrassatum occurred between years, but significant yearly differences in mean abundance were recorded from 1988 through 1993 (P < 0.05). There were no statistical differences in B. incrassatum parasitization between males and females or juvenile and adult otters.

Natural infection by Paramphistomoidea Stiles and Goldberger, 1910 trematodes in wild Marsh Deer (Blastocerus dichotomus Illiger, 1815) from Sérgio Mottas's hydroelectric power station flooding area.

Studies on helminthfauna of marsh deer Blastocerus dichotomus Illiger, 1815 are rare, although helminthic diseases are an important cause of mortality in these animals. Fifteen male and female adult marsh deer from Sergio Motta's hydroelectric power station flooding area at Paraná River which died during the capture and quarantine procedures, between 1998 and 1999, were necropsied. Three trematodes species, Paramphistomum cervi, Balanorchis anastrofus and Zygocotyle lunatum, all belonging to superfamily Paramphistomoidea, were identified. The obtained trematodes were identified, counted and their respectives descriptors of infection were determined. All necropsied animals were infected by helminths. Paramphistomum cervi was the most prevalent species, while Zygocotyle lunatum was found in only one animal.
