Leaflet No 1002 - Swine Paratyphoid (Salmonellosis Necrotic Enteritis), C R. Toop

Bulletins 1 - 2999

Paratyphoid is an infectious disease of pigs which is likely to make it appearance wherever pig raising is practised.

It may occur in an acute septicaemic form which is often rapidly fatal and accompanied by serious mortality and in a sub-acute or chronic form known as necrotic enteritis which is characterised by unthriftiness and scouring. The out breaks occurring in Western Australia are principally of the acute type and they are usually associated with the introduction of pigs from saleyards.

Quantitative Sugar Estimations In Pleural Fluid - An Aid To Diagnosis, John E. Peterson

Medical Arts and Sciences: A Scientific Journal of the College of Medical Evangelists

In a study of 33 cases of serous effusion it would appear that determination of the sugar content of the pleural fluid may provide an early clue to the etiologic diagnosis.

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 Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata

Harold W. Manter Laboratory of Parasitology: Library Materials

Gizzard-worms of poultry, Cheiloapirura hamulosa, are nematodes occurring in the gizzards of chickens and turkeys.

Summary and Conclusions

Previous to this report the carriers for the gizzard-worm in Hawaii were unknown. Recent investigations by the writer have shown that the flour beetle, Tenebroides nana, and the sand hopper, Orchestia platensis, collected from poultry farms in the Territory of Hawaii have been found naturally infested with the infective larvae of the poultry gizzard-worm, Cheilospirura hamulosa. Out of 8 laboratory-raised chickens to which there were fed about 2,300 grasshoppers that had been collected in an endemic gizzard-worm area, …

Some Monogenetic Trematodes From The Galapagos Islands And The Neighboring Pacific, Frank Grose Meserve

School of Biological Sciences: Dissertations, Theses, and Student Research

Introduction

Trematodes are parasitic, unsegmented, flattened (rarely cylindrical) worms. They have ventral, anterior, posterior or median attachment organs. The sense organs are poorly developed. The mouth is terminal or ventral and subterminal. The intestine is usually forked with or without lateral branches. The animals, with few exceptions, are hermaphroditic. The ovary is usually single. They have one, two, or more testes. The development is direct with only one host in the ectoparasitic Monogenea and indirect in the Digenea which have two or more hosts. The digenetic trematodes usually parasitize vertebrates which serve as their primary hosts and invertebrates (Mollusca) which …

The Health Of The School Child With Special Reference To Heart Cases, Annette G. West

Bachelors’ Theses

The first of the generally accepted objectives of education is health. The importance to the community of the health of its children can hardly be over-emphasized when it is fully realized that the children of to-day are the bread winners and the parents of to-morrow. The health of our children is the foundation upon which the welfare of the community depends. To conserve the health of the child is as much a function of the state as it is to conserve the natural resources. To investigate the evils that exist and to remedy all that may be remedied without transgressing …

An Inquiry Into The Cause Of The Increase Of Tuberculosis Of Swine, L. Van Es, H. M. Martin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The great increase in the number of swine found to be tuberculous presented a problem, the solution of which appeared to be desirable before adequate control measures could be devised or recommended. In the hope that a solution of the problem may be found this station undertook an investigation and attempted by experimental inquiry to determine the infection type of the tuberculosis associated with the animals which constituted the bulk of the retentions. In view of the apparent increased incidence and spread of tuberculosis among poultry in a large hog raising section, of which Nebraska forms a part, the experimental …

Summary Of Two Years' Study Of Insects In Relation To Pellagra, Allan H. Jennings

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

With the growing interest in pellagra, following the authoritative recognition of its presence in the United States in 1907, the study of its etiology was taken up by various investigators and the several theories of causation were subjected to close scrutiny.

Prominent among these theories was that of insect transmission, first advanced by Sambon, who limited this function to the species of blood-sucking gnats comprising the genus Simulium.

The importance of the disease and the possibility of such a factor in its causation, led the Bureau of Entomology, late in 1911, to undertake an investigation of the subject …

Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

The danger in using isolated sentences from an article as a basis for interpreting the author's theories, is generally recognized, but sometimes the most careful workers fall into the trap. Once the mistaken interpretation is published, it may be copied over and over again until it rises to the dignity of a dogma.

A striking illustration is afforded by the practical unanimity with which writers on the subject of insects and disease credit Dr. Josiah Nott with being the earliest to formulate definitely the theory of mosquito transmission of yellow fever.

Nuttall, in his classic monograph On the Role …

Studies On Nebraska Parasites, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

The intimate relations in which domestic animals stand to man have always made the transfer of parasites from the one to the other a matter of much greater probability than exists between man and the other forms of animal life. It is but natural that the most common species of human tapeworm come to man from his two chief sources of animal food-beef and pork. The chances of accidental infection, however, are evidently much greater in the case of those forms that are intimately associated with man, and hence clearly greatest in those he holds as household pets,the dog and …

A New Human Tapeworm (Taenia Confusa N. Sp.), An Entozoon, Probably Of Order Cestoidea, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

Somewhat more than a year ago a tapeworm was sent me which at first sight appeared decidedly unlike either Taenia saginata or Taenia solium. It showed the slender form and more delicate appearance of the latter, but was in length of segments even decidedly larger than the former species. Some notes were made at the time, and then, on account of pressure in other directions, laid aside to await opportunity for further study. This winter I received a second specimen which at once recalled the first, and on comparison was seen to be identical with it. A series of …

Bulletin No. 41 - Tuberculosis, F. W. Brewer

UAES Bulletins

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., …

The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

This article has been written for the general information of those engaged either on a large or on a small scale in stock raising in our own state particularly, and, while not intended to be a complete treatise on the subject, it includes references to those parasites which seem to be the most important or most likely to be found within our borders. The parasites of cattle, sheep, horse, hog, dog, cat, and man, which have many species in common, form the subject of this paper. The parasites of domestic fowl are, however, quite different from those considered here and …

Report Of The Zoologist, Henry B. Ward

Studies from the University of Nebraska Zoological Laboratory

In the report of last year was given a full summary of the present state of our knowledge concerning the parasites of man and the domestic animals. It is the intention of the following pages to review the parasitic fauna of the state of Nebraska so far as it is definitely determined, and also to include a list of some species reported but not accurately identified. The second section of this report presents a brief description of some important parasites not included in the group of worms, and hence not mentioned in last year's report. I shall omit all parasites, …
