'"To have its cake and eat it too:" US policy toward South Africa during the Kennedy administration

The assumption that US policy toward Africa was characterized by continuity during the cold war has recently been challenged by scholars who argue that President John F. Kennedy embarked on an African policy that was distinct from his predecessors. This may be true for black Africa, but Kennedy’s support for African nationalism did not extend to South Africa. This article reveals that Kennedy’s cold war priorities ensured continuity in US policy toward the apartheid state and, in some cases, additional cooperation as cold war crises increased the perceived importance of South Africa as an ideological and strategic ally and bastion against communism on a rapidly changing continent. This article also explores the role South Africa’s apartheid government played in this cold war alliance. The ruling National Party recognized its importance to US foreign policy goals and used this to stave off serious American criticism of its racial policies, deflect attention in the United Nations, and ensure continued economic and military cooperation with the United States.

Development of Detection Systems for the Sporangia of Peronospora Destructor

A monoclonal antibody that recognises components of the wall of sporangia of Peronospora destructor was raised. Tests using spores of higher fungi and other species of mildew demonstrated the specificity of the monoclonal. The antibody was used to develop lateral flow devices for sporangia of P. destructor. A competitive lateral flow format was developed which could detect onion downy mildew sporangia. Five-microliter gold anti-mouse IgM solution pre-mixed with 10 μl of P. destructor monoclonal antibody (EMA 242) proved the optimal concentration for detection of sporangia of P. destructor when applied to sample pads of lateral flow devices. Limits of approximately 500 sporangia of P. destructor could be detected by the absence of a test line on the lateral flow device within test samples. Using a scanning densitometer improved the sensitivity of detection. Further development and validation of the test is required if it is to be used for risk assessments of onion downy mildew in the field.
