RESUMO

An enrichment broth developed in our laboratory, fastidious broth (FB), was compared with two commercially available broth media, supplemented thioglycolate broth and enriched eugonic broth. FB supported the growth of a number of organisms that were not cultivatable in either of the other two media, including Corynebacterium jeikeium, Haemophilus influenzae, Neisseria gonorrhoeae, and Streptococcus pneumoniae. In addition, for several organisms that were able to grow in all three broths, including Neisseria meningitidis, Nocardia asteroides, and Actinomyces spp., both the time of incubation and the starting inoculum necessary to enable detection of growth were decreased significantly by using FB.
