ABSTRACT

With the recognition of Leuconostoc spp. as human pathogens, such mistakes in identiŠcation are now odd because of the unique results produced by leuconostocs in the tests listed in Table 25.1.6

Isolation Procedure. Generally, there are no special requirements for isolation of the group of bacteria discussed here; general recommendations for the culture of blood, body ³uids, and other specimens should be followed. These organisms are likely to be isolated on rich, nonselective media (e.g., blood and chocolate agars and thioglycolate broth) since they are nutritionally fastidious. If selective isolation of members of the vancomycin-resistant genera Leuconostoc and Pediococcus is desired, Thayer-Martin medium may be used to inhibit normal ³ora or other contaminating microorganisms.34
