A Technique For Physiologically Age-Grading Female Stable Flies, Stomoxys Calcitrans (L.), P. J. Scholl
A Technique For Physiologically Age-Grading Female Stable Flies, Stomoxys Calcitrans (L.), P. J. Scholl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A method of dissection followed by staining was initiated to allow physiological age- grading based on ovarian development in order to more completely describe the physiological development of adult female stable flies [Stomoxys calcitrans (L. )]. The gonotrophic developmental continuum from a non-differentiated cell in teneral females to mature eggs at the time of oviposition was first arbitrarily divided into six stages by using distinct landmarks within the developing oocyte . Then, nulliparous, uniparous, and biparous+ females were differentiated on the basis of the presence or absence of stained follicular relics in the ovariole sheaths. The combination of the …
Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus
Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …
Pig Typhus (Salmonellosis Suis), L. Van Es
Pig Typhus (Salmonellosis Suis), L. Van Es
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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
Studies On The Validity Of Swine Erysipelas Culture-Vaccines, L. Van Es, J. F. Olney, I. C. Blore
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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 …
The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore
The Effects Of Penicillin On E. Rhusiopathiae Infected Pigeons, L. Van Es, J. F. Olney, I. C. Blore
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.
Collected Observations Pertaining To Hog Cholera, L. Van Es, J. F. Olney
Collected Observations Pertaining To Hog Cholera, L. Van Es, J. F. Olney
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This bulletin reports on the following: (1) the possible role of Salmonella suipestifer in failed vaccinations (vaccination breaks); (2) excessive serum dosages as a cause of vaccination breaks; (3) experiments with crystal-violet hog cholera vaccine and (4) hog cholera vaccine of tissue origin, and (5) phenolized hog cholera virus as a possible vehicle for pathogenic contaminants.
Swine Erysipelas Infection In Man, L. Van Es
Swine Erysipelas Infection In Man, L. Van Es
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.
Swine Erysipelas. Revised Edition Of Research Bulletin 84, L. Van Es, C. B. Mcgrath
Swine Erysipelas. Revised Edition Of Research Bulletin 84, L. Van Es, C. B. Mcgrath
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Because of the more or less frequent occurrence of swine erysipelas on Nebraska farms it seemed proper that information on this subject be made available in the form of a Station publication, especially written to serve as a reference for veterinarians, who naturally are first appealed to when an as yet relatively strange disease appears among a herd of swine. Hence the text is written in a technical form for the sake of precision. In the preparation of the text the literature of countries in which for many years the disease has constituted a permanent problem has been freely consulted. …
An Inquiry Into The Influence Of Environment On The Incidence Of Poultry Diseases, L. Van Es, J. F. Olney
An Inquiry Into The Influence Of Environment On The Incidence Of Poultry Diseases, L. Van Es, J. F. Olney
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.
The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney
The Immunizing Value Of Commercial Hemorrhagic Septicemia Aggressins, L. Van Es, J. F. Olney
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In 1924, Gochenour published the results of certain experiments which tended to show that what he regarded as a specific aggressin possessed an immunizing value against hemorrhagic septicemia. The aggressin he prepared, by the use of a highly virulent strain of Bacillus bipolaris, was described as having adequately protected seven bovine yearlings against inoculations with the same organism which, when injected into four yearlings, used as virus controls, proved fatal to them. Soon after, if not simultaneously with, the publication of the Gochenour articles, hemorrhagic septicemia aggressin was placed on the market and apparently has since then been sold …

The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin
The Incidence Of Avian Tuberculosis In Mammals Other Than Swine, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The recognition of a very widespread and intense distribution of avian tuberculosis on the farms of a wide area of the United States, as well as the involvement of a mammalian species also, brought to the foreground the question whether or not the great prevalence of poultry tuberculosis could be of importance also from a public health point of view. This phase of the problem not only pertains to the people on the farms but likewise is of fundamental importance to the consumers of poultry produce. European authors had already identified the avian tubercle bacillus in human lesions while in …
On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer
On The Nature And Cause Of "The Walking Disease" Of Northwestern Nebraska (Necrobiosis Et Cirrhosis Hepatis Enzootica), L. Van Es, L. R. Cantwell, H. M. Martin, J. Kramer
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.
An Inquiry Into The Cause Of The Increase Of Tuberculosis Of Swine, L. Van Es, H. M. Martin
An Inquiry Into The Cause Of The Increase Of Tuberculosis Of Swine, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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 …

Studies Of Immunity Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
As one of the phases of our inquiry an effort was made to acquire some general knowledge regarding the immunizing value (1) of sera prepared with the aid of Bacillus bipolaris septicus procured from cattle and swine or (2) of those alleged to be of service in the control or treatment of hemorrhagic septicemia in the species mentioned. The experiments reported in this publication were almost exclusively made with sera purchased from dealers in biologic products.
The Immunizing Value Of Commercial Vaccines And Bacterins Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin
The Immunizing Value Of Commercial Vaccines And Bacterins Against Hemorrhagic Septicemia, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In the course of certain studies having to do with hemorrhagic septicemia, we were particularly struck with the difficulties which we encountered in the immunization of susceptible laboratory animals (rabbits). This difficulty in no small degree excited our curiosity regarding the immunizing value of the considerable number of "Hemorrhagic Septicemia bacterins and vaccines" which during recent years have become such a prominent article of commerce. In the hope of securing some information relative to the immunizing value of the agents mentioned, we undertook a series of experiments in which the immunity of the bacterin and vaccine injected laboratory animals was …
The Value Of Commercial Vaccines And Bacterins Against Fowl Cholera, L. Van Es, H. M. Martin
The Value Of Commercial Vaccines And Bacterins Against Fowl Cholera, L. Van Es, H. M. Martin
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
A great prevalence of the disease known as fowl cholera has naturally stimulated an interest in possible means of prevention and especially in those which may bring about a more or less lasting immunity. Vaccines which were favorably reported by some failed utterly in the hands of others, so that on the whole no substantial advantage has been gained. Vaccines and bacterins are nevertheless constantly urged on poultry owners confronted with disease and the Experiment Station is frequently called upon to give an opinion on their value or to recommend any special preparation. In order to comply with those demands …
