Bakererpes Fragilis N. G., N. Sp., A Cestode From The Nighthawk (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The examination of an Eastern Nighthawk (Chordeiles m. minor (Forster)), collected September 25, 1945, at Marion, Ohio, revealed numerous, very small cestodes free in the lumen of the small intestine. About fifty specimens were found, but, because of the delicate strobila of this species, few were entire.
Although these cestodes were very thin and translucent, the preparation of well-stained whole mounts presented unusual difficulty. Best results were obtained with a mixture of Ehrlich's and Delafield's haematoxylin stains. Frontal and transverse serial sections, cut at 10 and 15 μm, were made.
This cestode clearly belongs in the sub-family Dilepidinae, but, …

The Digenetic Trematodes Of Marine Fishes Of Tortugas, Florida, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

189 species of digenetic trematodes are reported from teleost fishes of the region of Tortugas, Florida. Among these are recognized: 44 new species, 9 new genera, 44 new combinations, 14 new synonyms, and 51 new host records. Several genera and species are considered synonyms of those previously named.

Of 237 species (approximately 2,039 specimens) of teleost fishes examined, 182 species or 76.8% were parasitized by adult, digenetic trematodes. Most of the host species harbored from one to three species of trematodes; 79 (or 43.4% of the 182) had a single species of trematode. Two fishes, however, were each susceptible to …

Observations On Some Helminths Parasitic In Ohio Turtles, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The examination of a number of turtles, collected in Ohio, has disclosed at least thirty-three species of parasitic helminths. Little information is available on the parasites of turtles in the Central States, and it is the purpose of this paper to present data resulting from examinations made on 128 turtles, of seven species.

Membership Relations Of The Utah Poultry And Farmers' Cooperative, Glen T. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Commercial egg production in Utah has developed gradually since 1920. Production of eggs increased from 142 million in 1924 to 433 million eggs in 1946. The percentage of total farm income of the state derived from the poultry industry increased from 5.3 percent in 1924 to 23.1 percent in 1946 and at the present time constitutes the largest income of any farm enterprise in this area. Factors influencing this development are: 1. High prices resulting from the war period of 1917 to 1920 followed by the depression period when prices were low. 2. The organization of cooperative egg-marketing associations. 3. …

Ec1549 External Parasites Of Chickens And Ddt, Ephriam Hixson, Martin H. Muma

University of Nebraska-Lincoln Extension: Historical Materials

Extension circular 1549 discusses external parasites of chickens and DDT.

Suggestions For The Handling Of Certain Mammals, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

For experimental work, it is often desirable to handle the smaller wild mammals more freely than usual methods allow. Howell (Journal of Mammalogy (1937) 18(4): 513) suggests the feeding of pentobarbital sodium in milk or other food. While this may be satisfactory for animals accustomed to captivity, it can hardly be used for those newly captured.

Pullorum Disease In The Coot, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among specimens collected on March 8, 1945, at Buckeye Lake, Ohio, were a number of coots (Fulica americana). When the latter were examined for parasitic infection, it was noticed that the ovary of one specimen was deformed, and much enlarged when compared with those of other birds of this species collected on the same day. No other lesions were detected macroscopically, and the bird appeared to be in normal physical condition. The ovaries resembled those found in chickens affected with pullorum disease, and a pure culture of Salmonella pullorum was recovered.

A Redescription Of Taenia Taxidiensis Skinker, 1935, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Since the original description of Taenia taxidiensis Skinker, 1935,2 was based on an incomplete and apparently immature cestode, a redescription seems desirable.

The following description is based on 28 cestodes, taken from three infected badgers, Taxidea taxus (Schreber), all collected in southern Wisconsin. Of these, only one strobila had gravid segments, the others being immature. Most of the data given below are based on the single mature specimen, with additional measurements, where Possible, from the immature worms. No sections were made of these specimens, and the measurements given were taken fl·om stained wholemounts.

Andrya Sciuri N. Sp., A Cestode From The Northern Flying Squirrel, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among helminths taken from four northern flying squirrels (Glaucomys sabrinus macrotis Mearns) were two cestodes belonging to the genus Andrya. These represent an undescribed species. The infected flying squirrels were collected in or near tamarack bogs during February, 1947, near Millston, Jackson County, Wisconsin.

Pig Typhus (Salmonellosis Suis), L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Salmonellosis suis or pig typhus, also designated as pig typhoid, infectious necrotic enteritis, or "necro," is an infectious disease among young pigs. It constitutes a major factor in the mortality of juvenile swine, and as such must be regarded as a more or less perennial hazard in swine production. Infectious necrotic enteritis caused by Salmonella suipestifer is the subject of the present publication.

Studies On The Validity Of Swine Erysipelas Culture-Vaccines, L. Van Es, J. F. Olney, I. C. Blore

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In countries where vaccination against swine erysipelas has been practiced during the last half century, there is a consensus among veterinarians that the best results are obtained when the live culture-vaccine is not only fresh and highly virulent but is endowed also with a good capacity for growth on artificial culture media. Apparently avirulent culture-vaccines are apt to engender only a transitory immunity or fail altogether. The problem presented by undesirable culture-vaccines was deemed to be of such importance to the swine industry that this Station undertook a series of experiments, to determine what influences might be accountable for the …

Morphology Of A New Species Of Bat Cestode, Hymenolepis Roudabushi, And A Note On Hymenolepis Christensoni Macy, Ralph W. Macy, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examination of material of a species of Hymenolepis collected by Rausch from several species of bats taken near Marysville, Ohio, revealed that it was new. A series of specimens of the same species was collected in 1942 at Ames, Iowa, by Dr. Robert Roudabush. The new species, Hymenolepis roudabushi, is described.

New Records Of Macracanthorhynchus Hirudinaceus In Sciuridae, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

New records of Macracanthorhynchus hirudinaceus in Sciuridae, from specimens collected in central Ohio, including those from the fox squirrel (Sciurus niger rufiventer) and the chipmunk (Tamias striatus).

The Raccoon, A New Host For Microphallus Sp., With Additional Notes On M. Ovatus From Turtles, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Discusses the raccoon, a new host for Microphallus sp., with additional notes on M. ovatus from turtles.

Parasites Of Ohio Muskrats, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasites of the muskrat (Ondatra zibethica) have received considerable study, but little in Ohio. From March 20, 1943, to March 22, 1945, 70 Ohio muskrat carcasses were examined, most of them being obtained from trappers by Merrill C. Gilfillan, Leader of the Pittman-Robertson Muskrat Project in Ohio. The specimens were from seven localities: Lake Erie Marshes (28); Killbuck Valley Marsh (17, lacking liver and lungs); Walnut Creek (19) and Whetstone Creek (2), (Morrow County); Buckeye Lake (1); Little Scioto River, Marion County (1); and Union County near Marysville (2).

The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Advantage was taken of an opportunity to study the effects of penicillin on Erysipelothrix rhusiopathiae, the causative organism of swine erysipelas. Owing to the fact that swine cannot readily be infected with erysipelas by artificial methods, pigeons which are highly susceptible to the disease, were selected to serve as experimental animals. It was the purpose of these studies to ascertain whether or not the swine erysipelas bacillus is sensitive to the drug and incidentally to determine the possibility of finding application of penicillin in the treatment of swine.

The Plains Garter Snake, Thamnophis Radix, In Ohio, Roger Conant, Edward S. Thomas, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The announcement that Thamnophis radix, the Plains garter snake, occurs in Ohio and is not rare in at least one county, will surprise most herpetologists and students of animal distribution. Since the publication of Ruthven's monograph on the genus (1908), almost all authors have followed his definition of the range of this species, giving eastern Illinois as its eastern-most limit. Ruthven (p. 80), however, believed that radix very probably would be found in western Indiana, a supposition since substantiated by Schmidt and Necker (1935: 72), who report the species from the dune region of Lake and Porter counties.

Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt

Harold W. Manter Laboratory of Parasitology: Library Materials

The subfamily Loimoinae was named by Price (1936) for a peculiar monogenetic trematode, Loimos salpinggoides MacCal lum, 1917, from the gills of a dusky shark, Carcharias obscurus (Lesueur), at Woods Hole, Massachusetts, USA. Price (1938) redescribed this trematode, correcting several errors made by MacCallum. Manter (1938) described Tricotyle scoliodoni from a shark, Scoliodon terrae-novae (Richardson), from Beaufort, North Carolina, USA. He noted some similarities between Tricotyle and Loimos. The redescription of Loimos by Price increased these similarities.

Swine Erysipelas Infection In Man, L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The preceding decade witnessed the introduction and spread within this state of a hitherto uncommon disease of swine. This disorder, swine erysipelas, has gradually become disseminated throughout Nebraska's swine population until it has developed into a major problem of preventive veterinary medicine. Its appearance, furthermore, added another to our list of animal maladies which are communicable to man. The latter consideration may serve as warrant to review what is known about the part played by swine erysipelas as a human disease, to describe its more salient features and to examine them from epidemiological, clinical, pathological and prophylactic viewpoints.

The Effect Of Sulfanilamide On The Spleen, Kidney, And Erythrocytes Of The Albino Rat, Paul M. Bergen

Bachelors’ Theses

Sulfanilamide today is recognized somewhat as a magical drug since it is being used in the cure of so many different diseases. Therefore it was my desire to experiment with it. The problem which the author has endeavored to solve has been, as the title implies, just what effect the drug has upon the blood, the cells of the spleen and the kidney. It has been my aim to verify or refute the findings of experimenters who have delved in the field previous to my experimentation, l and to attempt to give some explanation for the findings.

Resistance To Staphylococcus Aureus In White Rats, Robina B. Langill

Bachelors’ Theses

An investigation of bibliographies shows that staphylococcus aureus in its pathogenic potentialities has been extensively investigated from varied points of view and with frequently conflicting results.

Staphylococcus aureus is most frequently associated with furuncles, wound infection, and minor skin abcesses. Occasionally, however, due to extreme lowered resistance or other conditions not fully understood, staphylococcus causes a septicaemia which is attended by an 80% mortality rate. Post-mortem examinations of the victims of such septicaemia show an extensive invasion of all organs of the body by the bacteria but more particularly a hyperplasia of the lymph nodes, the spleen and thymus, indicating …

An Inquiry Into The Influence Of Environment On The Incidence Of Poultry Diseases, L. Van Es, J. F. Olney

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The principal purpose of the investigation reported here was to evaluate, if possible, hygienic measures, and in addition to gather whatever information might become available pertaining to the relation of certain disorders to a given poultry population after its exposure to their specific etiologic factors. The experiments were conducted on a piece of ground upon which poultry had not been maintained for many years, if ever.

A New Genus Of Distomes (Trematoda) With Lymphatic Vessels, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The trematodes described in this paper are but two of over 100 species collected from marine fishes in 1934, during the third G. Allan Hancock Expedition to the Galapagos Islands. The author's presence on this expedition was sponsored in part by the Carnegie Institution of Washington. A brief preliminary report on the trematodes collected has been made (Manter, 1934) and a more complete report on the digenetic forms is in preparation. An early description of these two forms is felt justified in view of their significance in connection with the phylogeny of the Distomata. The author has already indicated (Manter, …

Digenetic Trematodes Of Fishes From The Galápagos Islands And The Neighboring Pacific, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During January, February, and March of 1934 it was the· privilege of the writer, aided by the Carnegie Institution of Washington, to accompany the third Allan Hancock Expedition to the Galápagos Islands. A preliminary note concerning the trematode parasites collected has been published. Several papers dealing with various helminths collected have appeared. The present paper deals with the digenetic trematodes collected from fishes. Five hundred and thirty-two fishes, including nearly one hundred different species, were examined. Approximately 80 per cent of the species and 43 per cent of the individuals harbored some kind of trematode. Meserve records 22 species of …

Feeding And Care Of Calves, R. R. Thalman

Nebraska Agricultural Experiment Station: Historical Circulars

It is not infrequent that considerable difficulty is encountered in raising calves with limited amounts of milk or none at all. Requests for information on calf gruels, mixed grain feeds, and commercial supplements are frequent enough to make a short circular upon this subject seem desirable. Furthermore, as the more diversified agricultural program gets under way these requests are increasmg.

Comparative Physiology Of Actinomyces In Relation To Potato Scab, Mitrofan M. Afanasiev

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present work was undertaken with the purpose of investigating the physiology of different strains of A. scabies as compared with saprophytic Actinomyces. By a comparative study of these groups, it was thought that differences in the physiology of the two might be found which would give a better understanding of the nature of this parasitism and also of the metabolism of Actinomyces in general. In addition, it was hoped that the determination of the factors influencing the parasitism of Actinomyces might establish a basis for the development of more efficient methods of controlling scab diseases. The present investigation …

A Study Of The Relation Of Temperature To Antibody Formation In Cold-Blooded Animals, Earl C. Mcdaniel

Biology ETDs

It is an established fact that when warm-blooded animals are inoculated with foreign protein, in a great many instances they become immune, due to the formation of antibodies specific for the protein injected. In warm-blooded animals the body temperature is constant. The question naturally arises as to what the situation would be with regard to antibody formation in a cold-blooded animal where body temperature is not constant; also what part, if any, the temperature of the body would have to do with the antibody formation.

In a careful review of the literature practically nothing could be found in having direct …
