Sporadic Bovine Encephalomyelitis
Sporadic bovine encephalomyelitis (SBE) is a specific infections disease of cattle caused by an agent belonging to the psittacosis-lympho-granuloma group of viruses. This disease is not of frequent occurrence in this country, so many livestock men and veterinarians are not familiar with it. In herds where SBE has occurred it has sometimes accounted for serious loss, not only in deaths but also in weight loss. SBE is important to veterinarians from the standpoint of differential diagnosis as it is often mistaken for shipping fever or various diseases affecting the nervous system. Outbreaks of SBE in eastern South Dakota and western Minnesota have afforded material for observation and study of the disease This bulletin reports the results of the studies at this laboratory together with reference to contributions by others
Studies on Control of Fowl Cholera
Fowl cholera is a contagious disease of domestic fowls and many wild birds caused by a bacterium, Pasteurella multocida. It is one of the oldest known infectious diseases of poultry. In South Dakota, fowl cholera has been a poultry disease of major importance for many years. Experimental work was undertaken at this station in 1944 to study fowl cholera as related to this area and to investigate the development or improvement of control measures to more effectively prevent losses from this disease. This bulletin is a report of that work
