Incorporation Of Carbon-14 Metabolites Into The Sex Pheromon 26-Dichlorophenol Of Dermacentor Andersoni Stiles; And The Disruption Of Pheromone Activity In D. Andersoni And D. Variabilis (Say) By Quinones, Daniel Martin Gainsburg Apr 1981

Incorporation Of Carbon-14 Metabolites Into The Sex Pheromon 26-Dichlorophenol Of Dermacentor Andersoni Stiles; And The Disruption Of Pheromone Activity In D. Andersoni And D. Variabilis (Say) By Quinones, Daniel Martin Gainsburg

Biological Sciences Theses & Dissertations

The Rocky Mountain wood tick, Dermacentor andersoni Stiles, injected with (u-14c) sodium acetate or DL-(benzene ring-u-14c) tryptophan for in vivo studies, was found to produce sex pheromone, 2,6-dichlorophenol, containing 14c activity. Ambiguous results were obtained with L-(u- 14c) tyrosine, and no incorporation of 14c label into pheromone was observed with DL-(ring-u- 14c) phenylalanine or DL-(side chain-3-14c) tyrosine. Attempts were made to determine the site of synthesis, but in vitro studies proved inconclusive.

Disruption of sex pheromone activity in D. andersoni and the American dog tick, D. variabilis (Say) was achieved …

Dirofilaria Immitis In The Wild Canids Of Illinois, Thomas J. Kick Jan 1980

Dirofilaria Immitis In The Wild Canids Of Illinois, Thomas J. Kick

Masters Theses

The heartworm, Dirofilaria immitis, is widespread in dogs in North America and has been reported in wild canids in many states. This is a report of this parasite in hearts removed from coyote, red fox and gray fox carcasses collected in Illinois. A total of 415 coyotes had a significantly higher infection rate (23.6%) than 225 red foxes (3.6%) and 99 gray foxes (3.0%). Infection rates in red foxes and coyotes were significantly higher in or near the Wabash Border Natural Division along the eastern side of the state, suggesting a relationship between infection rates and this region.

Notes On Seasonal Variation And Infectivity Of Haemogamasus Reidi, A Vector Of Hepatozoon Griseisciuri, On Eastern Gray Squirrels, Sciurus Carolinensis, Mohammed Bashiru

Masters Theses

Five hundred and twenty-two squirrels were trapped and retrapped from a population in Montgomery County, Maryland during 1974-1975. One hundred and forty-one squirrels were found to harbor an average of 10.6 mites (Range 175-1). While male squirrels outnumbered females (79 vs 62) females harbored more mites than males (829 vs 666). During the spring the average number of mites per captured squirrel increased to an average of 18.1 per squirrel. The average declined to 6.8, 4.8 and 3.3 per squirrel in summer, fall and winter respectively. Throughout the collection period adult female mites were by far more numerous on hosts …


Flystrike In Sheep : Secondary And Tertiary Flies Striking Sheep In Western Australia, N Monzu Jan 1979

Flystrike In Sheep : Secondary And Tertiary Flies Striking Sheep In Western Australia, N Monzu

Journal of the Department of Agriculture, Western Australia, Series 4

Unlike primary species of blowflies, the secondary and tertiary species of flies cannot initiate a strike, but their activity in the presence of the primary blowflies becomes significant in the death of struck sheep. This is particularily so when the hairy maggot blowfly is involved. Future management of sheep flocks to minimise deaths may require recognition of these secondary and tirtiary flies.

This article presents some basic facts about these flies.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The morphology of Parascaris equorum of horses was studied; light and scanning electron microscopy were used. Late fourth-stage larvae have narrow, rectangular lips bearing few, large. triangular, irregularly spaced denticles and the lips are not markedly set off from the body. The cutick of the late fourth stage is completely transversely striated, with incomplete longitudinal ridges creating a brickwork pattern; longitudinal alae are present. Total body lengths of fourth-stage larvae range from 10 to 32 mm. A single molting fourth-stage male was found to be 33 mm long. Early fifthstage nematodes have wide, trilobate lips with a deep transverse groove …

Capillaria Sp. From Cryptotis Parva, Joseph N'Dong Jan 1978

Capillaria Sp. From Cryptotis Parva, Joseph N'Dong

Masters Theses

Twenty-nine Cryptotis parva were trapped at Lincoln Log Cabin State Park in Coles County Illinois between 22 December 1976 and 31 January 1978. Trapped specimens were necropsied and examined for the presence of helminth parasites. Nematode infections were found to be present in eight (27.2%) of the shrews collected with five (17.2%) of the males and three (10.3%) of the females infected. Three adult female nematodes were recovered from the small intestines of the host specimens, described and identified as the genus Capillaria. No male Capillaria were obtained and therefore species identification was impossible. However, the general appearance of …


Epizoic Protozoa Of Planktonic Copepoda And Cladocera From A Small Eutrophic Lake, And Their Possible Use As Indicators Of Organic Water Pollution, Michael Stevens Henebry Jan 1978

Epizoic Protozoa Of Planktonic Copepoda And Cladocera From A Small Eutrophic Lake, And Their Possible Use As Indicators Of Organic Water Pollution, Michael Stevens Henebry

Masters Theses

The epizoic protozoa of planktonic copepoda and cladocera from a eutrophic lake (Ashmore Lake, Coles County, Illinois) were studied over a 13-week period in the summer and fall of 1975. All organisms were collected with a 125 micron mesh plankton net. Epizoans (all peritrichs and suctorians) were hosted by three of four species of copepods and four of the ten species of cladocerans. The percentage of total organisms hosting epizoans varied significantly (0.001 alpha level) by month, but averaged 11.6 percent. This high occurrence of epizoans was thought to be related to the highly-eutrophic conditions existing in the lake. If …

Immunization Of Rats Against Mesocestoides Corti (Cestoda) By Subcutaneous Vaccination Of Living Tetrathyridia And By Passive Transfer With Serum, Jerry Y. Niederkorn Jan 1977

Immunization Of Rats Against Mesocestoides Corti (Cestoda) By Subcutaneous Vaccination Of Living Tetrathyridia And By Passive Transfer With Serum, Jerry Y. Niederkorn

Journal of the Arkansas Academy of Science

Laboratory rats were subcutaneously vaccinated with 100 live tetrathyridia of Mesocestoides corti (Cestoda) and subsequently intraperitoneally challenged with 50 tetrathyridia. Necropsy 30 days postinfection revealed that vaccinated rats harbored 97.4% fewer worms compared to control rats. In a second experiment, passive transfer of immunity was accomplished by immune serum from subcutaneously vaccinated rats. Rats receiving immune serum harbored 33.4% lighter worm burdens compared to normal serum recipients.

Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri Jan 1977

Blood Parasites Of Squirrels From Coles And Lake Counties In Illinois, Nicholas I. Obiri

Masters Theses

Hepatozoon and microfilariae are described from the blood of fox and gray squirrels captured in Coles and Lake Counties in Illinois during 1976 and 1977. The hepatozoon species is identified as Hepatozoon griseisciuri on the basis of parasite morphology and hosts. A higher rate of infection (35.7% : 11.1%) was observed in gray squirrels than in fox squirrels and more adults were infected than juveniles. No microfilariae were found in gray squirrels but fox squirrels had a 57.1% infection rate with no difference based on age. The observed microfilariae are similar to that described by Davidson from Maryland gray squirrels …


Endoparasites Of Cats In Two Central Utah Communities, Thomas W. Sawyer Jul 1976

Endoparasites Of Cats In Two Central Utah Communities, Thomas W. Sawyer

Theses and Dissertations

A survey of the endoparasites of 100 stray cats in central Utah was conducted. Each cat was euthanized, and the entire alimentary tract, gall bladder, bile duct, heart, respiratory and excretory systems were excised and examined for endoparasites. Fecal samples were examined by a sugar flotation technique. Parasites identified and number of cats infected were: Isospora felis 5; I. rivolta, 4; Dipylidium caninum, 1; Hydatigera taeniaformis, 10; Toxocara mystax, 43; and Physaloptera sp., 2. One ectoparasite, Cheyletiella parasitivorax, was identified in the feces of 4 cats. Dipylidium caninum and T. mystax are known to cause accidental infection in humans and …


Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser Jun 1976

Parasites Of California Marine And Estuarine Fish, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

While working on the parasites of several California marine fish, it was difficult to find out which parasites had been reported from our fish. Pertinent sources were scattered over a number of journals, covering many years. We compiled this list because we felt there was a need for a single source which would give all the parasites infecting California marine fish. As "marine fish" was a somewhat vague term, we decided to use it in a broad sense and included estuarine and anadromous fish in the survey. In addition, we have included records from landlocked populations of anadromous fish, such …


The Arthropod Ectosymbionts Of The Fox Squirrel In Coles County, Illinois, Jeanine L. Stanis Jan 1976

The Arthropod Ectosymbionts Of The Fox Squirrel In Coles County, Illinois, Jeanine L. Stanis

Masters Theses

The body surface areas of 18 squirrels (Sciurus niger) were calculated by regions, and the numbers and densities of the ectoparasite populations present on each region determined. Four species representing four genera of arthropods were recovered. The louse, Neohaematopinus antennatus was the most abundant organism with Orchopeas howardii, Haemagamasus reidi, and Dermacentor variabilis being also present. The average population density of all parasite species combined was highest on the back and decreased on the belly, tail, legs, and the head respectively. Body regions showing greatest average total population densities were different for males and females. The …


Blood Parasites Of Illinois Wild Turkeys, Ulrike G. Guenthner Jan 1976

Blood Parasites Of Illinois Wild Turkeys, Ulrike G. Guenthner

Masters Theses

Blood smears, from 152 wild turkeys (Meleagris gallopavo silvestris) killed during hunting seasons in southern Illinois, were examined for blood parasites. Haemoproteus meleagridis infected 34% of the 83 adult and 19% of the 69 immature turkeys. Of the infected birds, 54% had one or two infected cells per 5000 erythrocytes and 78% had one to five. Infection rates were significantly higher in counties along the Mississippi River than in Pope County, located about 40 miles east of the river. Other parasites specifically searched for but not found were Leucocytozoon, Plasmodium, Trypanosoma and microfilaria.

Taxonomy And Zoogeography Of Lemmus Spp. (Rodentia: Arvicolinae), With Notes On Laboratory-Reared Lemmings, Robert L. Rausch, Virginia R. Rausch Jan 1975

Taxonomy And Zoogeography Of Lemmus Spp. (Rodentia: Arvicolinae), With Notes On Laboratory-Reared Lemmings, Robert L. Rausch, Virginia R. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Lemmings of the genus Lemmus Link, 1795, have long attracted interest because of the high numerical densities attained at intervals by their populations. In earlier times, in northern Europe, such events seemed so remarkable as to be explained by some as a consequence of the animals' having fallen from the sky (HaGSTROM 1749). During the last 25 years, lemmings have been the object of intensive ecological investigation in Eurasia and North America, although there has been no consensus concerning their taxonomic relationships. In 1959, a colony of brown lemmings from arctic Alaska was established in our laboratory, primarily to provide …

Gastro-Intestinal And Abdominal Helminths Of White-Tailed Deer (Odocoileus Virginianus) From Carroll And Jo Daviess Counties In Northern Illinois, Jeffrey Joseph Hodge

Masters Theses

Forty-four white-tailed deer shot by hunters in November and December, 1971, in Carroll and Jo Daviess counties in northwestern Illinois were necropsied for gastro-intestinal and abdominal helminths. Five species of gastro-intestinal nematodes were found: Gongylonema pulchrum, Ostertagia odocoilei, Haemonchus contortus, Trichuris ovis and Nematodirus sp. Setaria yehi, a filiariad nematode, was found in the abdominal cavity. Moniezia benedeni was the only cestode found. No trematodes were recovered. Differences in numbers and kinds of parasites found in northern Illinois and southern Illinois are discussed. Prevalence increased with host age for certain species of parasites and decreased or …


Parasites From Gizzard Shad, Dorosoma Cepedianum, In Lake Charleston, Illinois, Francis M. Yabai Kaikumba Jan 1973

Parasites From Gizzard Shad, Dorosoma Cepedianum, In Lake Charleston, Illinois, Francis M. Yabai Kaikumba

Masters Theses

Eighty gizzard shad (Dorosoma cepedianum) from Lake Charleston, Charleston, Illinois were examined for parasites. Eight fish were parasitized. Three fish contained the acanthocephalan Tanaorhamphus longirostris, three fish harbored cestodes of the genus Glaridacris and two fish had the nematode Camallanus oxycephalus. The latter is here reported for the first time from gizzard shad. Twenty fish were infected with the fungus Saprolegnia sp. The numbers of helminth parasites harbored by shad are less than reported for other forage fish. However, the incident of parasitism reported in this study is greater than that reported by previous workers.
