The Effect Of The Parasite Hymenolepis Diminuta On Iodine Economy In The Rat, David Gourdon Holmes

Theses and Dissertations

A balance of iodine within the rats is important for the maintenance of normal thyroid function. Because of Hymenolepis d[imi]nuta's affinity for certain nutrients, it may upset norma[l] iodine balance in the rat. To determine this, tapeworm-infected and non-infected rats were given 125Iodide orally and the percent uptake of iodide by the thyroid and the amount of radioac[tiv]ity in the tapeworms was determined. The percent distribution of the radio-iodinated compounds in the thyroid, tapeworms and feces was also determined. These procedures were repeated except 125Thyroxine was administered orally. There was a decrease in percent iod[id]e uptake by thyroids of tapeworm-infected …

Bibliography Of Diseases And Parasites Of Marine Fish And Shellfish (With Emphasis On Commercially Important Species), Carl J. Sindermann

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The literature on diseases and parasites of marine animals has been accumulating at an accelerating rate in recent decades, and at a seemingly geometrical rate in the past few years. Reviews of selected aspects of the subject have appeared (Cheng, 1967; Sindermann, 1966; Sindermann and Rosenfield, 1967). References listed in these papers include a significant, but still a small part, of the available literature. With the proliferation of journals in many languages throughout the world, a complete bibliography, even in a narrow area of research, is almost an impossibility. Then too, the daily appearance of new published information represents an …

A Survey Of The Helminth Parasites And Coccidia Of Cattle And Sheep In Utah Valley, Joseph Carl Fox

Theses and Dissertations

A survey of gastro-intestinal parasites in cattle and sheep in Utah Valley was conducted. Cattle in the valley were not seriously parasitized by helminths, whereas sheep usually had heavy helminth infections. Ten genera of helminths and 8 species of coccidia were identified in cattle in the valley, and 14 genera of helminths and 8 species of coccidia were identified in sheep. In conjunction with the survey, meteorologic studies were conducted May through September, 1909, to ascertain the effects which irrigation had upon micro-environments on grass pastures in relation to the development of free-Iiving stages of gastro-intestinal nematodes of ruminants. The …

Dogs, Tapeworms, Cysts : And Soiled Sheep, Department Of Agriculture, Western Australia

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

To protect our export markets it is necessary to meet the required standards and to eliminate as far as possible any sources of cysts, contamination, blemished carcasses or other defects in meat.

Some of these things are beyond the control of the individual farmer, but there are some things he can do to help ensure that the sheep he sends to abattoirs are free of defects which threaten export markets.

Feeding And Care Of The Farm Dog, J B. White

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

Most farmers acknowledge the value of a well trained dog when handling sheep, but few appreciate that without correct care and feeding such a dog may reduce their profits and constitute a hazard to the health of themselves and their families.

Cysticercus Ovis : Sheep Measles, G C De Chaneet

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

CYSTICERCUS OVIS, commonly known as sheep "measles", has come into prominence in the last few years because of the rejection of affected carcasses by overseas markets. Recently it was one of the causes of a complete ban on imports of Australian mutton by-the.iJnited States and Canada.

A Control Programme For Cheesy Gland In Sheep, M R. Gardiner

Hydatid Disease In Western Australia, G C De Chaneet

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

BECAUSE hydatid disease is a disease of humans as well as animals, every dog owner should be aware of the conditions that perpetuate hydatids and the methods of control.

The incidence of hydatids in Western Australia in the past has not been high.

However, the increase in sheep numbers over recent years, together with the intensification of farming methods, may lead to a rise in incidence unless stock owners, particularly sheep farmers, take steps to control the disease.

The Incidence And Intensity Of Haematozoa In The Common Crow (Corvus Brachyrhynchos) Of Western Washington, Ronald E. Scarvie

All Master's Theses

The purpose of this study was to determine the incidence and intensity of blood parasites in the common crow (Corvus brachyrhynchos). The following observations on the protozoan genera Haemoproteus, Leucocytozoon, Plasmodium and Trypanosoma with observations on the nematode group microfilaria, are based entirely on materials collected at Auburn, Washington during the spring of 1970.

Despite the numerous studies on prevalence of blood parasites in various birds, there have been few attempts to study the relative incidence and intensity of haematozoa in blood and tissue smears taken from the common crow. So far as the author has been able to ascertain, …

A New Genus Of Trematode (Digenea: Gorgoderidae) From The Ureter Of Tuna Fish (Thunnus Thynnus Maccoyii) In Australia, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

A large, digenetic trematode is described from the ureter of the tuna Thunnus thynnus moccoyii from southern Australian waters. It represents a new genus and species, Cetiotrema crassum (subfamily Gorgoderinae) distinguished by the size and shape of the body, the caeca being distant from the sides of the body, the uterus being intercaecal, the vitellaria arising as three claviform lobes on each side and the seminal vesicle at least partly anterior to the genital pore.

The genus is close to Phyllodistomum Braun; P. carangi Manter, 1947, is considered to belong to Cetiotrema; P. lancea Mamaev, 1968 is very similar …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

PIGS may become infected by viruses which also cause disease in other animals (for instance foot-and-mouth disease) but there are two virus diseases worthy of special mention because they cause clinical disease in pigs only.

Practical Disease Prevention In The Pig Herd, R B. Richards

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

DISEASES cause loss in pig production through mortality, poor growth rate and reduced food conversion efficiency.

The cost of drugs and expert advice causes further economic loss, and the dangers to public health and to other livestock in a community are serious and often-neglected considerations.

Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson

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

Indications from a continuing sheep trial at Margaret River are that farmers in high rainfall areas could increase stocking rates and lamb growth rates by lambing in September- October rather than July-August.

The results also indicate that farmers in the area may be spending more than necessary on worm control.

Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Cercariac of Schistosoma mansoni were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.

Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10^-4 μg ± 6.6 x 10^-4 μg.

Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.

After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol …

A Brief History Of The Namru-3 Medical Zoology Program, Harry Hoogstraal

United States Naval Medical Research Unit 3: Publications

The NAMRU-3 Medical Zoology program began during Easter week of 1950. We had just closed the NAMRU-3 field station at Torit, in Equatoria Province of soulheastern Sudan, and were heading homeward to the United States. However, the offer to remain in Egypt for a year or two to develop a Medical Zoology department at NAMRU-3 provided an interesting challenge after working for several years in tropical forests and grasslands of Africa and other continents. We shall briefly describe subsequent events under four headings: (1) Medical Zoology in Egypt, (2) Ticks and Tickborne Diseases of the World, (3) Kala Azar in …
