Strongyluris panamaensis n. sp. (Nematoda: Heterakidae) and other helminths from the lizard, Anolis biporcatus (Sauria: Polychrotidae), from Panama.

Strongyluris panamaensis n. sp. from the intestine of Anolis biporcatus collected in Panama is described and illustrated. Strongyluris panamaensis represents the 30th species assigned to this genus and the fourth from the neotropical region. Strongyluris panamaensis can be easily distinguished from all other neotropical species because it has the shortest spicule. In addition to S. panamaensis, 3 species of Trematoda, Mesocoelium monas, Parallellopharynx arctus, and Urotrema scabridum, and 3 species of Nematoda, Crytosomum penneri, Oswaldocruzia bainae, and Piratuba digiticauda, were identified.

[Studies On Intestinal Trematodes In Korea Xiv. Infection Status Of Loaches With Metacercariae Of Echinostoma Cinetorchis And Their Development In Albino Rats]

The metacercariae of Echinostoma cinetorchis (Trematoda: Echinostomatidae) were found infected in the loaches (Misgurnus anguillicaudatus) purchased from two local markets in Korea. Identification of the metacercariae was done after obtaining adult worms from experimentally infected albino rats. Brief course of worm development in rats was also observed up to 28th post-infection day. The results are as follows: The metacercariae of E. cinetorchis were detected from 5 (10.9 %) out of 46 loaches examined and the average metacercarial burden per infected loach was 34.4. They were always found from the posterior abdominal wall. The worm recovery rate from 8 rats was 24.6 % in average. It was observed that the rate decreased according to age of infection; from 40.7 % after 6 days to 15.0 % after 28 days. The adult worms were morphologically characterized by the presence of head crown with dorsally uninterrupted collar spines, 37-38 in number, and the tendency of migration or disappearance of testes. So that they were identified as Echinostoma cinetorchis Ando et Ozaki, 1923. The development of worm was very rapid during 6-10 days after infection and became much slower thereafter. During the rapid worm growth the development of genital organs was more prominent than that of non-genital organs. From the results it is concluded that the loach is involved in the life cycle of E. cinetorchis in this country and may take a role for infection source to animals and man. It is also confirmed that migration or loss of testes is the distinct specific character of this echinostomatid fluke.

Babesia moshkovskii (Schurenkova, 1938) Laird and Lari, 1957; from the prairie falcon, Falco mexicanus, in Wyoming; with comments on other parasites found in this host.

Babesia moshkovskiiwas found in the blood of 6 of 30 downy (D) Prairie Falcons and in none of 5 adults (A) from Wyoming. Intestinal parasites included Neodiplostomum (C) spathula (A,3), Cladotaenia globifera, (A,1), Physaloptera sp., (A,1), and Serratospiculum amaculatum, (a,4). ornithodorus concanensis, (D,3), Thrassis francisi, (D,1), Opisocrostis sp., (D.1), Degeeriella rufa, (D,2), Simulium (E.) canonicola (D,2), and an unidentified hippoboscid fly, (D,2) were external parasites. It is considered that the soft tick, O. concanensis, is the most likely vector of the hematozoon. The morphological forms of B.moshkovskii are described and discussed. This is the first report of an avian babesoid on this continent.

Severe parasitism in an opossum.

Chronic debilitation and anemia were observed in a free-living opossum (Didelphis marsupialis) heavily parasitized by Physaloptera turgida, Brachylaima virginianum, and Cruzia americana. Chronic interstitial pneumonia associated with Capillaria aerophila and a metastrongyloid nematode also was present.

Effect of selected anthelmintics on three common helminths in the brown pelican (Pelecanus occidentalis).

The effect of selected anthelmintics (albendazole, fenbendazole, piperazine dihydrochloride and clorsulon) against three major helminths (Contracaecum multipapillatum, Mesostephanus appendiculatoides, and Phagicola longus) were studied in 29 brown pelicans (Pelecanus occidentalis). Albendazole and fenbendazole were highly effective against all three parasites. Clorsulon had moderate effect against M. appendiculatoides and poor effect against C. multipapillatum and P. longus. Piperazine dihydrochloride had no effect against these helminths.

Prevalence of metazoan parasite infections in five species of Asian macaques.

Necropsy examination was performed on a total of 697 wild-caught macaques of five species. Helminthic parasites were found to be prevalent among these macaques, with species of Strongyloides, Oesophagostomum, Anatrichosoma, Trichostrongylus, and Gongylonema being the most common patent infections. Some of the larval stages of nematodes (ascarids, spirurids), cestodes (hydatid, Sparganum), and pentastomids grew into adults in appropriate definitive hosts upon experimental feeding, enabling species identification.

Parasitic disease in humans: the extent in Canada.

Much is being said, often dramatically, about the potential hazards of parasitic diseases in Canada, but little or no attempt has been made to determine the true extent of the problem. Indigenous parasite pathogens are recognized in resident Canadians, and pathogens are acquired by travellers abroad or reported from immigrants. The role of each of these categories is important in the characterization of the problem of parasitic diseases in Canada. From data provided by provincial laboratories and hospitals it is estimated that 1 person in 1000 will spend 1 day per year in hospital because of intestinal parasites, and 1 in 100 each year will have a diagnosis of intestinal parasitic infection made from examination of a stool sample.
