Immunology Of Coccidiosis Caused By Eimeria Bovis In Calves, Clyde Merle Senger

Biology

Coccidiosis is a disease which can occur in most vertebrates and certain invertebrates as a result of infection by organism classified in the Order Coccidia of the Class Sporozoa, Phylum Protozoa. Host animals become infected by ingesting the exogenous resistant stage, the oocyst (Figures 1 and 2). These oocysts may be ingested with contaminated food and water or from the bodies of other animals. In the intestine of the new host, the oocysts rupture and release a specific number of sporosoites depending upon ths genus of coccidia involved. The liberated sporesoites penetrate epithelial or other cells of the intestine and …

Evidence Against The Transmission Of Staphylococci By The Mosquito Culex Tarsalis, John R. Molenda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Staphylococcal synovitis is a pathological condition of birds involving primarily the wing and leg joints. It is frequently referred to as arthritis, osteoarthritis, bursitis, hock disease, staphylococcosis, and weak leg.

The disease has been reported throughout various parts of the world as having been found in a great variety of avian hosts including pheasants, chickens, pigeons, canaries, geese, ducks, grouse, and turkeys.

Miner (1945) presented results of a survey made on turkey diseases in Sanpete County, Utah, which indicated staphylococcal synovitis to be responsible for the greatest numbers of deaths. His report cites this infection as having been found in …

Bulletin No. 384 - Virus And Viruslike Diseases Of Stone Fruits In Utah: A Handbook For Their Identification And Control, B. L. Richards, L. C. Cochran

UAES Bulletins

Intensive research over the last 20 years has shown that many of the previously unexplained and seemingly mysterious disorders of stone fruit trees in Utah are infectious diseases caused by viruses. Others were shown to be the result of noninfectious genetic abnormalities or of adverse chemical and physical factors in the environment of the plant. The purpose of this handbook is to help orchardists and others recognize these diseases and disorders and understand better their etiology or cause. The handbook will also bring together basic information which will aid in their control.

Experimental Infections With Eimeria Zurnii In Calves, Rulan S. Hansen

Biology

Bovine coccidiosis is an infectious disease, commonly called bloody scours or red diarrhea, that sometimes causes heavy losses among calves. It is of great economic importance in many parts of the world, including the United States. An economic loss of an estimated 10 million dollars occurs annually in the United States as a result of bovine coccidiosis.(2) It is known that Eimeria zurnii Rivolta, 1878, is one of the 2 most pathogenic species of coccidia in cattle. At present little information is available on this species. Further information concerning E. zurnii would be of value in establishing sound prophylactic measures …

Reactions Of The Rocky Mountain Muskrat Ondtra Zibethica Osoyoosensis (Lord) To Drought Conditions At Ogden Bay Bird Refuge, Utah, Edward V. Saunders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Perhaps no mammal on the North American Continent has received more attention in the literature than the muskrat (Ondatra spp.), but little of this material pertains to the reactions of muskrat populations to drought conditions. The author was unable to find any literature containing information on the reactions of the Rocky Mountain muskrat Ondatra zibethica osoyoosensis (Lord) to drought conditions in Utah. This information is of vital importance in formulating muskrat management programs in the State.

On many farms the muskrat population represents the greatest cash value of any kind of wildlife, and they utilize swamp areas and marshlands …

Relative Activity Of Sulfaquinoxaline, Regasul, And Parabis In The Control And Prevention Of Coccidiosis In Young Chicks, Eldon R. Child

Biology

Coccidiosis is one of the most common and most serious infectious diseases of poultry. It is a widely studied disease and a vast amount of information has been accumulated, but its vicious attacks on poultry flocks have not been eliminated. Cecal coccidiosis, caused by the parasite Eimeria tenella, is of extreme importance in young chicks. It is considered responsible for the loss of about ten per cent of all chicks hatched in the United States (1); the economic loss in poultry from all species of coccidia is estimated to amount to about 10 million dollars annually (2). In areas …

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. …

A Survey Of The Incidence Of Trichinosis In Northern Utah, As Indicated By The Intradermal Skin Test And Post-Mortem Examinations Of Diaphragms, H. W. Merrill

Biology

Definition and History. Trichinella spiralis, the causative organism in trichinosis, and commonly termed the "trichina worm," was first known by its encysted larval stage in the muscles of man as early as 1821, when it was noted by Tiedemann in Germany, and again in 1828, when it was seen by Peacock of London. Mr. Paget, who was a student at the Saint Bartholomew Hospital in London, noted whitish specks in the muscles of an Italian, aged 45, who had died at the hospital. Suspecting these specks to be produced by a minute internal parasite, Mr. Paget gave portions of …

Transactions Of The Plague Control Conference Of The United States Public Health Service And Twelve Western States, United States Public Health Service

Elusive Documents

The plague problem is potentially of grave public health importance. The history of this disease over a period of centuries shows that it has several times assumed epidemic proportions, especially in cities. History also shows that when the disease appears in bubonic form contracted from rat fleas, it sooner or later may assume the pneumonic type and be spread from person to person with fatal results.

From the evidence presented to the conference it appears that complete control of plague is not economically feasible without a great increase in Federal, State, and local expenditures. It is recommended that funds are …

Circular No. 28 - Contagious Abortion In Mares And Cows, H. J. Frederick

UAES Circulars

Contagious abortion is a cause of great loss to the stock growers of Utah. There is an urgent demand from nearly all parts of this State for information relative to this disease. In an effort to satisfy this demand a few facts regarding the disease as they are now known are here presented. It is not the purpose of this circular to report original research, but merely to describe the disease as it exists among animals in this State. The causes, symptoms, diagnosis, and methods of combating and controlling this great menace to the livestock industry are all considered.

One of the most dreaded diseases which afflict the human race is "Tuberculosis." It is also the most fatal, as estimates based on reliable statistics show that at least one out of every eight of mankind die from the disease. It ha~ been a scourge throughout historical time and has been known under the various names of Phthisis, Consumption, Wasting Disease, Tuberculosis, etc. The researches of Professor Koch of Germany in 1881 and since that date have proved that not only Tuberculosis has been produced by the germs of which he was the discoverer, but that Scrofula, Tabes, Hydrocephalus, etc., …
