Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

Harold W. Manter Laboratory of Parasitology: Faculty Publications

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.

Two New Species Of Plistophora (Microsporidea) From North American Fish With A Synopsis Of Microsporidea Of Freshwater And Euryhaline Fishes, Robert E. Putz, Glenn L. Hoffman, Clarence E. Dunbar

United States Fish and Wildlife Service: Publications

Two new species of Microsporidea, Plistophora salmonae from steelhead and rainbow trout (Salmo gairdneri) and Plistophora cepedianae from gizzard shad (Dorosoma cepedianum) are described. Schizonts to spores of P. cepedianae were found at one time within the same cyst, while only sporonts and spores of P. salmonae were found within the cyst. An illustrated synopsis of the known Microsporidea of freshwater and euryhaline fishes is given.

Eimeria Aurati N. Sp. (Protozoa:Eimeriidae) From Goldfish (Carassius Auratus) In North America, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In March, 1962 this laboratory received some goldfish for disease diagnosis from Mr. Richard Rice, Mercersburg, Pennsylvania. Seven of 29 fish examined were infected with Eimeria. These fish had long, whitish, opaque fecal casts hanging from the anus. The casts were composed almost entirely of oocysts. When shed, they sank to the bottom and looked somewhat like "spent" tapeworms (Figs. 1, 2). The infected fish were very lethargic and their intestines were swollen with contained fluid. Although I believe that the Eimeria is pathogenic, a heavy infection of other parasites made this difficult to determine. These fish had apparently …

Studies On Myxosoma Cartilaginis N. Sp. (Protozoa: Myxosporidea) Of Centrarchid Fish And A Synopsis Of The Myxosoma Of North American Freshwater Fishes, Glenn L. Hoffman, Robert E. Putz, Clarence E. Dunbar

United States Fish and Wildlife Service: Publications

Myxosoma cartilaginis n. sp. is described from the cartilage of Lepomis macrochirus (bluegill), L. cyanellus (green sunfish) and Micropterus salmoides (largemouth black bass).  The development of the parasite is described from naturally infected fish which were held in spore-free water after infection.  The sporoplasm invades cartilage, and becomes a multinucleate trophozoite which forms pansporoblasts, each of which produces 2 to 4 spores.  The first spores appear in 7 weeks.

The histopathology in the above fish consists at first of little cellular reaction, but after 4 to 5 months epithelioid granulomas appear arround some of the spore masses.  Cartilage liquefaction is …

Contents For Proceedings: Conference On Estrous Cycle Control In Domestic Animals, July 9-10, 1964

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This publication is a record of the papers presented at a conference on estrous cycle control in domestic animals, held July 10-14, 1964 at the University of Nebraska. Objectives of the conference were to review the status quo of research on this problem, to provide a forum for exchange of ideas and experiences, and to point up the direction of future research.

Some Side-Effects And After-Effects Of Experimental Endocrine Treatments Used To Modify The Natural Estrual Rhythm, L. E. Casida

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The side-effects and after-effects to be considered in this discussion are those which grow out of experimental attempts to modify the natural estrual rhythm, and which have a bearing on the subsequent fertility ofthe animal. They are the effects that at one-and-the-same- time are the despair and the hope of workers on technological control of reproduction. They are the despair in that they detract from our immediate ability to control reproduction; they are the hope in that we may be able to learn more about the reproductive process in our attempts to analyze and understand them.

Roles Of Hypothalamus And Hypophysis In The Control Of The Estrous Cycle, A. V. Nalbandov

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The interrelation between the hypothalamus and the anterior pituitary gland has been firmly established. It is not the intention of this report to review the literature on this extensive subject. Such reviews are available in "Advances in Neuroendocrinology" (Nalbandov, 2), and since the time of this publication many papers on this subject have appeared in current journals. For the purposes of the present discussion a few fundamental facts will be restated, but the major part of my presentation will deal with my own views of the research areas which should be of special interest to animal scientists concerned with phenomena …

Hormonal Control Of Reproductive Activity In The Ewe, J. F. Wagner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

There are many advantages which result from synchronizing the estrous period in a ewe flock. In situations where the ewes are not hand bred to the ram, the synchronization of estrus makes the application of artificial insemination (AI) techniques more efficient. Detection of estrus usually is more reliable in a synchronized flock. Only 3 to 4 days are needed to detect estrus in 90 percent of a synchronized flock, whereas 16 to 18 days are normally required. This allows the AI technician to plan the number of breedings and have semen available. When hormones are given in the feed, an …

Life Cycle And Development Of Prosthorhynchus Formosus (Van Cleave, 1918) Travassos, 1926, An Acanthocephalan Parasite Of Birds, Gerald D. Schmidt, O. Wilford Olsen

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The life cycle of Prosthorhynchus formosus (Van Cleave, 1918) Travassos, 1926 is presented. The terrestrial isopods Armadillidium vulgare, Porcellio laevis, and P. scaber served as experimental intermediate hosts, and chickens and turkeys as experimental definitive hosts. After ingestion of the eggs by the isopod, the acanthor emerges from its shells within 15 minutes to 2 hours, enters the gut wall of its host, and remains there 15 to 25 days. It then migrates to the hemocoel and develops through the acanthella stage to the infective cystacanth by the 60th to 65th day of infection.

Studies On The Helminth Fauna Of Alaska. Xli. Observations On Cestodes Of The Genus Diplogonoporus Lönnberg, 1892 (Diphyllobothriidae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The study of a collection of cestodes assigned to the genus Diplogonoporus Lönnberg, 1892 disclosed but two species, D. balaenopterae Lönnberg, 1892, and D. tetrapterus (von Siebold, 1848) (provis.). These cestodes occur characteristically in marine mammals but occasionally are found in terrestrial hosts; D. balaenopterae is recorded for the first time from the domestic dog, and it is concluded that D. grandis (Blanchard, 1894), from man, is conspecific with D. balaenopterae. The latter species is recorded for the first time from the humpback whale, Megaptera novaeangliae (Borowski). The relatively small D. tetrapterus, a common parasite of the Steller …

The Specific Status Of The Narrow-Skulled Vole (Subgenus Stenocranius Kashchenko) In North America, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

On morphological and zoogeographical grounds, discussed in the present paper, it is concluded that the narrow-skulled vole in North America, previously designated Microtus (Stenocranius) miurus Osgood, is conspecific with the Eurasian M. (Stenocranius) gregalis Pallas. Fourteen subspecies in Eurasia and 5 in North America are now recognized, but it is probable that the number in Eurasia will be reduced through future investigation. The Eurasian subspecies of this vole comprise two major groups, of which one occupies the tundra zone and the other occurs across central Asia below latitude 60° N; their geographic ranges are largely separate …

Phytotoxic Substances From Soil Microorganisms And Crop Residues, T.M. Mccalla, F.A. Haskins

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The role of organic matter in the growth of plants has been a subject of much investigation and controversy since the sixteenth century. During the early era, decomposition of plant residues and green and animal manures provided a primary source of minerals for plant growth. In addition, beneficial effects on soil structure and water-holding capacity were attribute to the presence of organic matter. With the development of agricultural chemistry culminating in the work of Liebig in the nineteenth century, it was discovered that plants could make satisfactory growth in the absence of added organic matter if suitable kinds and amounts …

Heritability In Relation To Selection Differential In Cattle, G. E. Bradford, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The concept of heritability as generally used, involves the assumption that additive genetic variance is a constant proportion of total variance over the entire range of phenotypes. If this assumption holds, selection response will be linearly related to selection differential. If not, prediction of selection response will not be possible from a knowledge of the phenotypic selection differential and the average proportion of additive genetic variance. Thus the validity of this assumption has a bearing on the design of efficient selection schemes for many situations. In the field of applied animal breeding, for example, this will affect such important questions …

Arctic Health Research Center, U.S. Public Health Service, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A program of research in Alaska was initiated by the United States Public Health Service in 1948, with the establishment of a field station in temporary facilities located at Anchorage. This station, officially designated the Arctic Health Research Center in May 1950, was founded largely as the result of surveys of health conditions in Alaska conducted during 1946 and 1947 by two committees representing the American Medical Association. The reports of these committees led Congress to pass a special appropriation bill to support the investigation of health problems in Alaska.

Six research sections were set up within the first year. …

Use Of Farm Resources As Conditioned By Tenure Arrangements, Virgil L. Hurlburt

Nebraska Agricultural Experiment Station: Historical Research Bulletins

How do tenure arrangements affect organization and use of resources within farm firms? Do lease terms and arrangements affect quantities and kinds of inputs? Does the tenant and the landlord each receive full earnings of the resources he contributes to the farm business? Which of the strictly tenure-oriented characteristics of farms, as contrasted with the general economic problems of all farms, help to explain differences between and within owner-operated, cropshare cash tenant-operated and livestock-share tenant-operated farms? These are the major questions to which answers were sought in the research reported here.

Using Fertilizer Nitrogen Effectively On Grain Crops, Robert A. Olson, A. F. Dreier, C. Thompson, K. Frank, Phillip H. Grabouski

Department of Agronomy and Horticulture: Faculty Publications

Fertilizer nitrogen is necessary for the efficient production of grain crops throughout the midwest. Farmers have recognized this need by tremendous increases in nitrogen consumption duhng the past decade.

Fertilizer nitrogen where needed for optimum yield usually increases slightly the total water used by the crop. The water required in making this optimum yield, however, is used a good deal more efficiently than where nitrogen is omitted. Nebraska studies on fertilizer economy have demonstrated nitrate leaching losses in some cases, especially serious on sandy soils of low water holding capacity and with irrigation. Strong circumstantial evidence also suggests denitrification of …

Bait Mixing Equipment Used In Vertebrate Pest Control, Percy F. Wright

Vertebrate Pest Conference Proceedings: 2nd (1964)

I would like to discuss with you the reason why agricultural commissioners are in the poison bait business. The following are excerpts from the Agricultural Code of the State of California. Section 100 describes a pest as follows: "Pest means any of the following that is, or is liable to be dangerous or detrimental to the agricultural industry of this State" and for the purpose of this talk only part two of this section is cited which states, "any form of animal life." This is the part which covers vertebrate pests. Section 102 states, "Each commissioner is an enforcing officer …

Forest Animal Damage Control, Nelson B. Kverno

Vertebrate Pest Conference Proceedings: 2nd (1964)

As a nation we have gained world recognition for our ability to utilize our resources. In forestry our greatest accomplishments have been in the mechanization of harvest methods and in improvements in forest products. The renewal of this resource has been our greatest neglect. Though the end of the 19th Century marked the beginning of the conservation movement, it was not until a half century later that the force of economics through the demands of a growing population made forest re-establishment more than just a desire. Conservation in itself is a Utopian concept which requires other motivating forces to make …
