ABSTRACT
Grouping of beta-hemolytic streptococcal strains was performed over a six months period on a total of 102 isolates. The purpose was to compare the Lancefield method with three different possibilities offered by the Co-agglutination technique. The results show that the Co-agglutination is as reliable as precipitin testing but it can be much more sensitive and rapid than any other method.

In rabbit corneal cells (SIRC strain), have been observed some mitochondria which, instead of containing the usual cristae, show triangular crystal-like figures as those previously described by other Authors in tissue cells of different animal species. Such curious geometric forms seem to derive from the inner membrane of mitochondria through a restructuration mechanism due to not very clear reasons about which some hypotheses are formulated.
