A portable water distiller having an insulated container for raw water and a removable cover for the container with a low pressure seal which engages the container wall. A condenser coil is provided in the cover along with a motor-driven fan, and inlet and outlet ports are provided about the periphery of the cover to allow cooling air to be drawn into the cover over the condenser coils and motor. An inlet tube connected to the condenser coil receives steam from the container generated by a heater connected to the container bottom.

A solid phase assay which specifically detects C-fixing ICs by reacting ICs or aggregated gammaglobulin in normal serum with matrix-bound F(ab')2 anti-C3 and measuring the amount of Ig by radioimmunoassay or enzyme-linking techniques, and means for carrying out the assay are disclosed.

Following the original isolation of Mycoplasma cloacale from a turkey in Great Britain, only one further turkey isolate has been obtained whereas the mycoplasma has been recovered from 2 species of wild ducks in Britain, and from 2 breeds of domestic ducks and from domestic geese in France.
