Bacteriology of rural water supplies of Mutenda community district of Chingola, Zambia.

The sources of water supply for drinking and other domestic uses available to the rural population of Mutenda was analysed bacteriologically by standard techniques (Presumptive and Differential Coliform tests (Wilson et al 1935), Ministry of Health (1946). The water sources include wells, bore holes, springs and rivers. Assessment of suitability by standard criteria showed that, the bore hole water was the only source of supply bacteriologically safe for drinking.

The viral etiology of acute respiratory infections in children in Uganda.

The role of viruses in respiratory diseases of young children in Uganda was studied. A viral etiology was established in 36% of the infections investigated. The most important pathogens were found to be respiratory syncytial virus and parainfluenza viruses, which were responsible for 26% of infections investigated.

Some characteristics of poliovirus strains isolated in Uganda between 1966 and 1971.

Sixty-five poliovirus strains were investigated in genetic marker tests in order to obtain information on the characteristics of polioviruses circulating in Uganda where, owing to the insufficient use of live poliovirus vaccine, poliomyelitis remained a serious public health problem. Of the type 1 strains predominant in both epidemic and non-epidemic years, 29 were studied for their antigenic fine structure. Based on their intratypic character, these strains proved to represent six different antigenic variants.
