Photographic recording of agar diffusion plates.
TLDR
It may be of help to those using the Ouchterlony5 and Mansi6 techniques if the successful system devised and regularly in use here is made more widely known.Abstract:
A NUMBER of requests have been received at this Establishment asking for details of the method and materials used for the photographic recording of agar diffusion plates1–4. It may be of help to those using the Ouchterlony5 and Mansi6 techniques if the successful system devised and regularly in use here is made more widely known.read more

Plant virus serology.
TL;DR: The most commonly used serological test in plant virology is without question the precipitin reaction, which is less laborious than those in free liquid, they require less antiserum, and provide more information on the homogeneity and purity of the reactants and on the size of and relationships among antigens.

Peripheral Rheumatoid Ulceration and Evidence For Conjunctival Collagenase Production
TL;DR: Direct evidence for collagenase involvement offers an exploration for the beneficial effects of conjunctival resection in patients with rheumatoid arthritis and peripheral corneal ulcerations.

Radial diffusion assay of tissue collagenase and its application in evaluation of collagenase inhibitors
TL;DR: A radial diffusion assay for tissue collagenase (EC 3.4.3) has been devised which is simple, sensitive and capable of application to large numbers of samples and has potential for clinical determinations since assay dishes may be prepared in advance and only 15 micronl of sample is required.

Pasteurella septica: the Occurrence of Type-Specific Polysaccharides containing Aldoheptose Sugars
A. P. Maclennan,C. J. M. Rondle +1 more
TL;DR: PIROSKY1 has shown that strains of Pasteurella septica produce lipopolysaccharide antigens with similar properties to the endotoxins of certain other Gram-negative bacteria.

TL;DR: Virulent and certain avirulent plague strains, however, produce smooth colonies although rough strains also occur, and rough forms referred to herein correspond to ‘TSR’ and not ‘TRU’.
