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).

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

The role of birds in the epizootiology of eastern encephalitis
Eastern encephalitis is a disease of horses, man, birds, and reptiles caused by a virus that in some hosts results in an inflammation of the brain. The causative virus belongs to a group classified as mosquito-borne encephalitides. This disease, more commonly called eastern equine encephalitis in the past, occurs from Wisconsin and Texas to the Atlantic coast and is particularly prevalent on our e
