Differentiation Of Fourth And Early Fifth Stages Of Parascaris Equorum (Goeze, 1782) Nematoda: Ascaridoidea, P. A. Pilitt, J. R. Lichtenfels, P. A. Madden

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The morphology of Parascaris equorum of horses was studied; light and scanning electron microscopy were used. Late fourth-stage larvae have narrow, rectangular lips bearing few, large. triangular, irregularly spaced denticles and the lips are not markedly set off from the body. The cutick of the late fourth stage is completely transversely striated, with incomplete longitudinal ridges creating a brickwork pattern; longitudinal alae are present. Total body lengths of fourth-stage larvae range from 10 to 32 mm. A single molting fourth-stage male was found to be 33 mm long. Early fifthstage nematodes have wide, trilobate lips with a deep transverse groove …

Viral Infections Of Domestic Animals, George A. Young

School of Veterinary and Biomedical Sciences: Faculty Publications

There is a strong tendency in current research on mammalian virus diseases to concentrate on virus activity at a cellular or subcellular level. This trend is summarized adequately by Enders in relation to viral replication as follows: ','The large and ever-increasing volume of published experimental work on viral replication strikingly reveals the central position of this phenomenon in contemporary virological research. There are good reasons, both biological and practical, underlying this intensive effort to understand, i n detail, how a virus particle, without energy transforming apparatus of its own, manages to utilize the metabolic equipment of the cell to produce …

The Corn-Stalk Disease In Cattle, Frank S. Billings

School of Veterinary and Biomedical Sciences: Faculty Publications

MORPHO-BIOLOGICAL CORRESPONDENCE BETWEEN TWO OR MORE MICRO- ETIOLOGICAL ORGANISMS NOT SUFFICIENT GROUNDS FOR PRONOUNCING THE DISEASES WITH WHICH THEY ARE CONNECTED IDENTICAL. The details of this discussion will be found in my report on the swine-plague. It is necessary, however, to touch upon the essential points here also. As was there shown, Hueppe asserts that the European diseases previously mentioned as being caused by a member of this group of belted, ovoid germs, viz., the “ Huhne Cholera, Kaninchen Septikasmie, und Wild Seuche ’ ’ are all one and the same disease, because their micro-etiological organisms have the same form, …

Keratitis Contagiosa In Cattle, Frank S. Billings

School of Veterinary and Biomedical Sciences: Faculty Publications

This is not a new disease by any means, so far as the United States are concerned, nevertheless I have been unable to find any description of it in the literature at my command. While new to myself until the past Summer, there have been quite a number of reports of its existence, and complaints about it, from farmers and breeders of cattle in some of the live-stock journals of our western States. Under these circumstances, it would seem that a description of its clinical phenomena and gross pathological lesions may not be without scientific interest to the opthalmologist, and …

Inoculation—Vaccination, Frank S. Billings

School of Veterinary and Biomedical Sciences: Faculty Publications

When one comes to discuss this question with the members of the profession as he casually meets them, he is often surprised to find how uncertain and clouded the prevailing ideas are upon the subject. In fact, the majority of physicians do not seem to have any clear conception of the act connected with the words “ inoculation ” and “ vaccination.”

Replicating Single-Cycle Adenovirus Vectors Generate Amplified Influenza Vaccine Responses, Catherine M. Crosby, William E. Matchett, Stephanie S. Anguiano-Zarate, Christopher A. Parks, Eric A. Weaver, Larry R. Pease, Richard J. Webby, Michael A. Barry

Head-to-head comparisons of conventional influenza vaccines with adenovirus (Ad) gene-based vaccines demonstrated that these viral vectors can mediate more potent protection against influenza virus infection in animal models. In most cases, Ad vaccines are engineered to be replication-defective (RD-Ad) vectors. In contrast, replication-competent Ad (RC-Ad) vaccines are markedly more potent but risk causing adenovirus diseases in vaccine recipients and health care workers. To harness antigen gene replication but avoid production of infectious virions, we developed “single-cycle” adenovirus (SC-Ad) vectors. Previous work demonstrated that SC-Ads amplify transgene expression 100-fold and produce markedly stronger and more persistent immune responses than RD-Ad vectors …
