Some Biological Aspects Of Lizard Eimerians, With A Description Of Eimeria Poinsettis N. Sp. From Sceloporus Poinsetti, David A, Colwell

All Master's Theses

A previously described eimerian, Eimeria sceloporis, from the northwestern fence lizard, Sceloporus occidentalis occidentalis, was observed for oocyst production, incidence and intensity of infection in both juvenile and adult lizards. In order to test the species specificity of Eimeria ahtanumensis, an attempted transmission was made to Sceloporus poinsetti, Sceloporus jarrovi, Sceloporus undulatus and Sceloporus occidentalis. During the winter of 1970-1971 fecal samples were collected from Sceloporus poinsetti to determine possible coccidial infections. The lizards were collected in September of 1970 in Hidulgo County, New Mexico and the ensuing investigation showed that nine of the thirteen adults were passing an intestinal …

The Influence Of Various Stress Conditions On Cholinesterase Levels Of Cattle Treated With An Organophosphorus Insecticide, Mitchell J. Wrich

Electronic Theses and Dissertations

Six-to 8-months-old Hereford heifers categorized as grubby or grub-free calves were used for this research. Forty calves were purchased in 1968 and also in 1969. The grubby calves were obtained from Highmore, South Dakota, an area where calves have a history of heavy grub infestations of both Hypoderma bovis (L.) and Hypoderma lineatum (de Villers). The grub-free calves were purchased in Fargo, North Dakota. Calves raised in this area seldom are infested with cattle grubs. Specified groups of calves were subjected to 30 minutes of continuous exercise or the withholding of feed and water for 24 hours prior to treatment …

Effects Of Feeding Leptaden To Dairy Cows, Sitakantha Dash

Electronic Theses and Dissertations

Leptaden is a herbal drug which was recently introduced to the market by Alarsin Pharmaceuticals, Bombay, India. It consists of the extracts of two indigenous medical plants, namely Leotadenia reticulata (Jeevanti) and Breynia patens (Kamboji) in equal proportions. In 1947, Patel first drew the attention of gynaecologists to the usefulness of Leptaden in habitual abortions and allied conditions in women and later on pointed out its lactogenic and galactagogue properties. His original observations are supported by growing clinical experience over a twenty year period of medical practice. Published clinical experience shows that in most cases Leptaden stimulates, lactation within twelve …

Discovery Of The Carolina Marsh Clam, Polymesoda Caroliniana (Bosc), A Supposed Florida Disjunct Species, In Everglades National Park, Florida, D.C. Tabb, D.R. Moore

Gulf and Caribbean Research

The presence of disjunct species of animals on either side of the Florida peninsula has been reported by a number of authors. The littorinid mollusk, Littorina irrorata Say, which has a range from Massachusetts to the Rio Grande of Texas, except for south Florida, is one such species (Bequaert 1943). The marsh crab, Sesarma cinereum (Bosc), is another example of an animal with a distribution from Virginia to the western Gulf of Campeche except for a break in southern Florida (Rathbun, 1918). Williams (1965) lists 23 species of crustaceans having interrupted distribution at the Florida peninsula. This report on discovery …

The frequency of recent publications offers some indication of the current worldwide interest in problems of fish teratology.

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp

Journal of the Arkansas Academy of Science

A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated when impoundment was complete. The Strawberry River was characterized by high alkalinity and pH, low carbon dioxide and turbidity, and adequate oxygen values. Plankton was characterized by limited numbers of Staurastrum, Gomphonema, and Rotatoria. Pool-riffle communities were ill-defined. Chironomidae, Oligochaeta and Ephemeroptera were dominant pool macroinvertebrates among 13 taxa collected. Of the 20 taxa collected in riffles Trichoptera, Ephemeroptera, Simuliidae and Chironomidae …

Ichthyofaunal Diversification And Distribution In The Big Creek Watershed, Craighead And Greene Counties, Arkansas, James T. Jenkins, George L. Harp

Journal of the Arkansas Academy of Science

Big Creek is a relatively small deltaic stream, in northeastern Arkansas, in an area of intense cultivation. Recently it has been dredged in the interest of flood control. Lost Creek and Mud Creek are the major tributaries of Big Creek and collectively drain the Big Creek watershed. The streams were found to have relatively low alkalinity, moderate carbon dioxide, adequate oxygen values, and relatively high turbidity. Channeling of Big Creek and Lost Creek has effectively destroyed distinct pool-riffle biocies and reduced the number of acceptable spawning areas. Lost Creek, also, receives effluent from residential dwellings, a secondary treatment sewage plant, …

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

PARASITIC gastro enteritis, caused by roundworms, is a common cause of economic loss in calves, yearlings and occasionally cows in south-western Australia. Losses could be prevented if stock owners realised the full effects of these parasites, and understood the causes of worm infestation.

Changes In Escherichia Coli Associated With Acquired Tolerance For Quaternary Ammonium Compounds, R. B. Maxcy, N. P. Tiwari, P. R. Soprey

Department of Food Science and Technology: Faculty Publications

Acquired tolerance for a quaternary ammonium compound produced a tolerance for a similar compound. Tolerance was associated with the structure and the extent of adsorption of the compound. Morphological changes and resistance to disruption by pressure and by sonic treatment accompanied the development of tolerance. An otherwise weakened culture evolved with the acquisition of tolerance. The maximum obtainable viable population density of tolerant cells in growth medium was approximately 5 %, of that obtained in the parent culture. Tolerant cultures died off more rapidly in the original growth medium as well as when washed cell suspensions were stored at 5 …

Antigenic Relationships In Seven Strains Of Tetrahymena, W.E. Engelhard, B.W. Mccashland

Papers in Microbiology

Tetrahymena, along with other genera of the family Frontoniidae, have been the subject of many scientific investigations concerning problems in protozoan physiology. Unfortunately in many instances, difficulty arises when attempting to identify properly the form that was used in the particular study. Until rather recently, relatively little had been accomplished by way of a comprehensive study of the interrelated genera, and of these very few have dealt with taxonomic problems serologically.

Observations On Parasite-Host Relationships Of Echinococcus Multilocularis Leuckart, 1863, In North Dakota, Robert L. Rausch, S. H. Richards

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Red foxes, Vulpes vulpes (Linnaeus), and small mammals were collected and examined during 1965-1969, to investigate parasite-host relationships of Echinococcus multilocularis Leuckart, 1863, in North Dakota. Comparative studies of this cestode were carried on concurrently through experimental infection of carnivores and rodents. In winter, red foxes in North Dakota exhibited high rates of infection of comparatively low intensity. Deer mice, Peromyscus maniculatus (Wagner), and voles, Microtus pennsylvanicus (Ord), were important intermediate hosts, but the larvae in deer mice produced fewer protoscolices. The strains of E. multilocularis from North Dakota and from St. Lawrence Island, Alaska, differ biologically, as indicated by …

Study Of Control Of Public Health Problems Using Irradiation, R. B. Maxcy, N . P. Tiwari, C. C. Anagnostis

Department of Food Science and Technology: Faculty Publications

Red meat, as exemplified by ground beef and pork, is subject to numerous opportunities for contamination and harborage of pathogenic organisms with the present commercial system of processing and distribution. An exploration was undertaken therefore to determine the usefulness of gamma irradiation for public health protection when applied to red meat. This work indicated that retail products are commonly heavily contaminated. The contamination can be reduced somewhat through central processing as shown by the data obtained from ground beef. Considerable numbers of the contaminants can be destroyed by irradiation at a 68 Krad level.
This work indicates that commercial ground …

Lysis Of The Rhizobiaceae, Craig Richard Baumrucker

Masters Theses

The following members of the Rhizobiaceae were tested for their lytic response to various treatments: Agrobacterium tumefaciens, Chromobacterium violaceum, Rhizobium phaseoli, Rhizobium trifolii, Rhizobium lupini, and Rhizobium japonicum. Lysis was observed in spent growth media and as a function of saline concentration, pH, buffer composition, disodium (ethylenedinitrilo) tetraacetate (EDTA) concentration, and lysozyme.

Cells were harvested by centrifugation, washed, and resuspended in various treatment solutions. The lytic response was followed spectrophotometrically.

The different responses of the six cultures was applied to a summation of reclassification proposals evolved through modern taxonomic techniques such as DNA homology …

A Variation Of The Standard Steepest Ascent Search Procedure For Response Surface Experiments, George Whitfield Cobb

Theses and Dissertations

The results of this chapter lead to a modification of the standard stopping rule which breathes new life into the method of steepest ascent, but which is unfortunately not sufficient to effect a total resuscitation. As expected, there is no uniformly optimum stopping rule, nor even a uniformly best test statistic; both the optimum statistic and the optimum test level depend on the model parameters y1 and y2. One can, however, adopt a compromise rule which works reasonably well for all parameter combinations by testing at the 25% level with the statistic zn = 1/2(yn -yn-2). In many cases the …

Glycogen Levels In Cardiac And Skeletal Muscle Of Rats Recovering From Exercise, Walter Talley Judd

Theses and Dissertations

In seeking answers to questions about how the human body functions under stressful situations, scientists, coaches, doctors, and athletes in general have all wondered about the role of exercise in the maintenance of good health. Good cardiovascular health, especially, is sought ardently, as it appears to be a major key to overall body fitness. Good cardiovascular health appears to go hand-in-hand with proper diet, proper rest, and proper exercise (1, 2).

The exercise phenomenon has attracted much attention and poses many questions. Just what is occurring when a person or an animal gets "in shape" by exercising. What bodily changes …

Activity Analysis Of Personnel On Patient Trayline Assembly, June Bishop

Loma Linda University Electronic Theses, Dissertations & Projects

The systems approach in food service administration is the initial step in analyzing current procedures to determine the effectiveness of resource utilization. Analysis begins with observation of a system to provide possible explanations of the system behavior.

The purpose of this research was to determine through work sampling the proportion of both productive and nonproductive labor time of operators on the tray assembly, the labor time and labor cost required in each position and for each meal, and to test the hypothesis that there was no significant difference between the productivity index (trays per minute) during Phase A and Phase …
