Abstract
UREA has been used by various authors1–3 for the extraction of bacteria. The work of Neter et al.4 encouraged me to study urea-treated Gram-negative bacteria (S. typhi, S. paratyphi B, S. cholerae suis and Shigella sonnei) in the indirect hæmagglutination reaction (for further details see Brodhage5).
