    An appraisal of the uricult dip slide method in the diagnosis of urinary infections
    (HMPG, 1973-05) Finlayson, M. H.; Coates, J. K.; Brede, H. D.; Mitchell, P.
    Uricult dip slide urine cultures were compared with standard laboratory plate cultures. Good agreement of bacterial counts was obtained after incubation at 37°C but not at room temperature. Tests of therapeutic activity of various drugs on the commoner organisms producing urinary infections, were done. The results suggested that such tests had no positive value. Uricult dip slides should be of value as a suitable transport and diagnostic medium for the diagnosis of urinary tract infections.

    Differentiation of Klebsiella Enterobacter Serratia organisms
    (Health and Medical Publishing Group (HMPG), 1975) Finlayson, M. H.; Coates, J. K.; Coldrey, N. A.
    Differentiation of 625 strains of bacteria which fulfilled the requirements laid down for the definition of Klebsielleae was carried out using 6 biochemical tests. 546 strains were identified as members of the genus Klebsiella, 46 of the genus Enterobacter and 33 of the genus Serratia.

    Escherichia coli serotypes associated with urinary tract infections in the Western Cape
    (Health & Medical Publishing Group, 1974) Brede, H. D.; Coldrey, N. A.; Coates, J. K.; Finlayson, M. H.
    Examination of 3,261 specimens of urine from patients with urinary tract infections led to the isolation of E. coli types from 933 samples (28.6%). Serological typing revealed 222 isolates (23.8%) as urinary or as enteropathogenic serotypes. The rest were untypable. The following urinary types were identified: O 1, O 2, O 4, O 5, O 6, O 7, O 9, O 11, O 18, O 39, O 75, the commonest being O 6, O 4, and O 75. Enteropathogenic types were O 26-B6, O 55-B5, O 86-B7, O 111-B4, O 112-B11, O 119-B14, O 124-B17, O 125-B15, O 126-B16, O 127-B8, O 128-B12, and O 142-B. Types O 112 and O 111 were the most prevalent. The 1973 pattern of urinary E. coli infections in the Western Cape differs from that found in other parts of the world. Type O 6 is most prevalent, followed by O 4, and O 75. The last is the most common type north of the equator. Other types were far less frequent. Crossreactivity between 14 V. cholerae strains and E. coli O 39 antiserum was proved, suggesting similarities between the enterotoxins of V. cholerae and pathogenic E. coli strains.
