Distribution and detoxication of toxaphene in Clayton Lake, New Mexico
The fate of toxaphene, applied in three treatments at a total calculated concentration of 0.05 p.p.m. to Clayton Lake, New Mexico, was followed over a 1.5-year period. A detailed description of the chromatographic method of analysis is given. Water concentrations of toxaphene were higher in leeshore samples than in windward samples for 2 weeks after the application; toxaphene levels then appeared

Studies of transmission of mycobacterial infections in Chinook salmon
THE INCLUSION OF VISCERA AND CARCASSES OF TUBERCULOUS ADULT SALMON IN THE DIET OF JUVENILE SALMONIDS is considered to be the major source of mycobacterial infections in hatchery-reared fish (Wood and Ordal, 1958; Ross, Earp, and Wood, 1959). In considering additional modes of infection, we speculated about transovarian transmission or a mechanical process arising from contamination of the ova at t

Intraspecific differences in serum antigens of red salmon demonstrated by immunochemical methods
The sera of most Alaskan red salmon (Oncorhynchus nerka Walbaum) were found to contain at least 14 antigenic components when tested by the double diffusion precipitin analysis method of Ouchterlony with antisera prepared in rabbits. Two of these components, designated antigens I and II, were missing from 116 of 125 blood samples from red salmon taken in Asian waters. In contrast, only 31 of 905 bl

An interim report on Sacramento River Chinook disease: A virus-like disease of Chinook salmon
An annually recurring disease among chinook salmмом (Oncorhynchus tahawytscha) FINGERLINGs at the National Fish Hatchery at Coleman, California, was reported by Ross, Pelnar, and Rucker (1960). They presented results of experimental investigation of the disease which established that the etiologic agent was filterable, highly virulent, and resistant to antibiotics and some of the more common chemi

Isolation of a pigment-producing strain of Aeromonas liquefaciens from silver salmon (Oncorhynchus kisutch)
Aeromonas salmonicida, the etiological agent of furunculosis in fish, is distinctive in the field of fish diseases in that it may readily be recognized by the water-soluble reddish-brown pigment formed on culture media containing tyrosine. Additional tests for the identification of this organism include blackening of the colonial growth when flooded with an aqueous solution of p-phenylenediamine a

Occurrence of Trypanosoma cruzi in Maryland
During 1954-1960, 2005 mammals of 18 species collected at the Patuxent Wildlife Research Center, Maryland, were examined for trypanosomes. T. cruzi was found in 10 raccoons between October 31 and November 30. Infection occurred in 2 percent of all raccoons sampled, and in 11.3 percent of the 80 raccoons sampled in November. Examination was by direct smears, stained smears and cultures of heart blo
