Virus diseases of salmonidae in the western United States. II. Aspects of pathogenesis
During the 10 to 15 years investigators from Europe and eastern United States have reported fish diseases of virus etiology. Rucker et al. in 1953 were the first to report a disease of possible virus origin in fish in the western United States. Since then many workers in the western states have described various epizootics caused by transmissible and filterable agents. The etiology and pathology

Changes in the bottom fauna of western Lake Erie from 1930 to 1961
Samples were collected at 40 stations in western Lake Erie in 1961 to determine the species composition, distribution, and abundance of macrobenthonic organisms and to document changes since 1930, when a similar survey was made. The fauna in 1961 was composed principally of Oligochaeta, Tendipedidae (7 genera), Sphaeriidae (15 species), and Gastropoda (at least 8 species). Stations with a high den

Infectious pancreatic necrosis: its detection and identification
Ultimate control of infectious pancreatic necrosis (IPN) in hatcheries depends largely upon learning where the virus occurs. To detect the presence of virus either susceptible fish or susceptible fish cell cultures may be used as test systems. In modern virology, it is generally agreed that cell cultures are more convenient, are usually a much more sensitive test system, and allow more rapid deter

Correlation between chemical structure and rodent repellency of benzoic acid derivatives
Sixty-five benzoic acid derivatives were either prepared or obtained from commercial concerns, tested for rat repellency, and their indices of repellency computed. The data from these tests were considered analytically for any correlation between chemical structure and rat repellency. The results suggest a qualitative relationship which is useful in deciding probability of repellency in other co
