RESUMO
The year 1992 was marked by restiveness in the ranks of junior hospital doctors throughout the coutry agitating for better tools to do their job; and for more equitable conditions of service; to the point of stopping work at the Muhimbili Medical Centre on 11 September in apparent sympathy with their nursing colleagues. This lecture is a cursory survey of the author's view on the probable genesis of the crisis and an attempt to indicate the possible role that the Medical Association of Tanzania could play in its resolution
RESUMO
The antibody titres in hamsters that were experimentally infected and in humans that were naturally infected with S. mansoni or S. haematobium were determined with the IFAT. The infection intensity was measured directly in the hamsters by counting the worms collected after perfusion and indirectly in humans by counting the eggs in faeces or in urine. In general antibody titre reflected infection intensity.

In a schistosomiasis endemic area two populations, one predominantly infected with S. haematobium and the other with S. mansoni, were examined with the IFAT using juxtaposed S. haematobium and S. mansoni antigen and with parasitological methods. In both populations: ---the serological prevalence was higher than the parasitological prevalence, ---a positive correlation was found betwen titre and egg output, ---focal fluorescence in antigen sections, which is a sign of a young infection, was found mainly in the younger age classes, ---the mean titre was higher for the homologous antigen but this preference was negligable in the population from the S. mansoni area.
