THE VETERINARY INFECTIOUS DISEASE ORGANIZATION (VIDO), an established labora-
tory concentrating on the study of infectious disease and immunological approaches to prevent
disease in domestic animals and THE ANIMAL BIOTECHNOLOGY GROUP, an interdisciplin-
ary team which includes faculty from Agriculture, Veterinary Medicine and Medicine and VIDO
and THE WESTERN COLLEGE OF VETERINARY MEDICINE at the UNIVERSITY OF
SASKATCHEWAN, SASKATOON, SASKATCHEWAN have the following positions available:
VETERINARY INFECTIOUS DISEASE ORGNIZATION:
IMMUNOLOGYAMMUNOCHEMISTRY-The Veterinary Infectious Disease Organization (VIDO), at the University of Saskatchewan, has a position for
an immunologist with a strong interest in developing vaccination regimes for infectious diseases of animals. Major projects are in the area of viral and
bacterial pneumonias and enteritities of cattle and swine. The applicant will be part of a large team of molecular biologists, immunologists and veterinarians
investigating mechanisms of enhancing immunity to recombinant DNA produced proteins or synthetic peptides as potential vaccines. Experience in
adjuvants would be a definite asset. Applicants should have a degree in microbiology or veterinary medicine, together with a Ph.D. in immunology with an
interest and experience in potentiation of immune responses to natural or synthetic viral and bacterial antigens, seriological techniques and assays for
humoral and CMI responses. A strong interest in the application of modern immunological techniques to the solution of problems related to the diagnosis
and control of infectious diseases of animals is essential.
Applications must be submitted by May 31, 1988.
MOLECULAR BIOLOGY/VIROLOGY-Two positions for individuals with expertise in molecular biology, cloning and expression of viral genes.
Expertise in various types of expression systems would be an asset. The level of appointment would be dependent on the individuals' expertise ranging
from the post-doctoral level up. These individuals will work with a team of virologists, molecular biologists, immunologists and veterinarians interested in
developing methods to prevent and control economically important viral diseases of the respiratory and enteric systems. The potential exists for a senior
virologist to become program manager of the virology group. In the latter case, experience in managing a number of projects using both conventional and
molecular virology approaches and interpersonal skills would be a prerequisite.
Inquiries and applications should be directed to:

ANIMAL BIOTECHNOLY GROUP:
IMMUNOLOGY/HORMONE REGULATION-The Veterinary Infectious Disease Organization (VIDO) in collaboration with the Animal Biotechnology
Group, which includes faculty from the Colleges of Agriculture, Veterinary Medicine and Medicine at the University of Saskatchewan is developing a
program to study immunological control of growth and reproduction in livestock. A position is available for an individuals interested in developing methods
of hormone immunoneutralization which will influence these production traits. Studies are underway in the area of growth, lactation, increasing
reproductive rates as well as sterilization. Applicants should have a Ph.D. in immunology with a strong interest in physiology. As part of the animal
biotechnology group, the candidate will have access to protein chemists, molecular biologists, animal scientists, veterinarians and physiologists.
Experience in application of monoclonal antibodies to hormone regulation would be an asset. The successful candidate should also have expertise in
adjuvants, conjugating antigens to various protein carriers and a variety of serological assays to determine immune responses to specific hormones.
Applications must be submitted by May 31, 1988.
MOLECULAR ENDOCRINOLOGIST/BIOLOGIST-Two positions for individuals with expertise in endocrinology at the molecular and systems
level. One position will emphasize cellular and subcellular aspects of growth factors and their receptors in studies of growth physiology. Experience in the
use of immunological techniques such as monoclonal antibody's production would be helpful. The other position will emphasize the mammalian
reproductive system and will employ immunological techniques to increase rates of ovulation, implantation and embryo survival.
