| [karyologic research on trematodes of the family schistosomatidae from northwestern chukota]. | peculiarities of chromosome sets of 4 schistosome species, parasitic in different mollusks from the chaun lowland were investigated. the karyotype of parthenitae of trichobilharzia sp. 1 (the intermediate host sibirenauta picta) consists of 18 elements, of which the 2nd and 6th pairs are submetacentric-metacentric, the other chromosomes are metacentric. the diploid chromosome set of trichobilharzia sp. 2 (the intermediate host anisus acronicus) includes 16 biarmed units. the first pair of metace ... | 1989 | 2616200 |
| response of leukocytes in chickens infected with the avian schistosome austrobilharzia variglandis (trematoda). | leukocyte levels were monitored weekly in chickens infected with the avian schistosome austrobilharzia variglandis. changes in relative and absolute numbers of leukocytes were recorded over a 7-week period beginning 1 week before exposure. there was a significant increase (p less than 0.001) in total leukocytes, peaking at 5.8 x 10(4) cells/mm3 on day 21 postexposure; controls had 2.4 x 10(4) cells/mm3 on that day. the leukocyte count declined over the next 3 weeks, returning to nearly normal le ... | 1986 | 3814005 |
| distribution of eggs and the host response in chickens infected with austrobilharzia variglandis (trematoda). | segments of cleared intestines from chickens infected with the marine (avian) schistosome austrobilharzia variglandis showed eggs clustered around branches of blood vessels on each side of the intestine. most of the eggs, as seen in sections, were found in the vessels or lamina propria of the mucosa. a comparison of distribution of eggs relative to the location of adults within the intestinal vessels suggested that eggs were deposited in mucosal vessels by ovigerous females. only immature eggs w ... | 1983 | 6685178 |

| skin surface lipids of the domestic chicken, and neutral lipid standards as stimuli for the penetration response of austrobilharzia variglandis cercariae. | lipids were extracted from the skin of 2-wk-old domestic chickens using sterile cotton gauze dampened with chloroform:methanol (2:1). preparative thin-layer chromatography separated the skin lipids into six major fractions: phospholipids, free sterols, free fatty acids, triglycerides, methyl esters, sterol esters. the penetration response of the marine avian schistosome cercaria, austrobilharzia variglandis, to chicken skin lipid fractions, and to neutral lipid standards, was tested by coating l ... | 1982 | 7131196 |
| investigation of the life cycle and adult morphology of the avian blood fluke austrobilharzia variglandis (trematoda: schistosomatidae) from connecticut. | this study was undertaken to expand the current knowledge of the life cycle and adult morphology of the avian schistosome austrobilharzia variglandis, which causes a marine cercarial dermatitis in new england. the specific objectives were to: (1) investigate the seasonality of the infection in the molluscan intermediate host, ilyanassa obsoleta; (2) determine which bird species are acting as natural definitive hosts for the parasite; and (3) characterize the morphology of the parasite using scan ... | 1995 | 7623201 |
| ilyanassa obsoleta (gastropoda) as a host for trematodes in delaware estuaries. | extensive data characterizing larval trematode communities in marine gastropods do not exist for many systems. the purpose here is to report on the infections encountered in delaware ilyanassa obsoleta and to compare this trematode community with certain others that have been well studied. over 15 yr, 11,774 i. obsoleta from 9 different estuarine habitats were examined. trematode parasitism, sex, and size were determined for each snail. in the total collection, 9 trematode species were encounter ... | 1997 | 9379280 |
| trematode accumulation by the estuarine gastropod ilyanassa obsoleta. | the accumulation of larval trematodes by ilyanassa obsoleta (gastropoda) at 2 estuarine sites in delaware was studied. initial infection status of snails was assayed by looking for shed cercariae. native snails (most already infected) were deployed at sites a and b, and sentinel snails (putatively uninfected) were deployed at site b. all were individually marked and, if found, reassessed for infection after being free 1-3 summers. himasthla quissetensis, lepocreadium setiferoides, zoogonus rubel ... | 1999 | 10386431 |
