Bergey's Manual of Determinative Bacteriology: A Key for the Identification of Organisms of the Class Schizomycetes

The genus Serratia.

The genus Serratia a member of the Enterobacteriaceae (see Introduction to the Family Enterobacteriaceae from the second edition.), is comprised of a group of bacteria that are related both phenotypically and by DNA sequence. The type species of the genus is Serratia marcescens. Some species and biotypes of Serratia produce a nondiffusible red pigment, prodigiosin, or 2-methyl-3-amyl-6-methoxyp...

Isolation of an oral filamentous microorganism.

In the past, a wide variety of unrelated oral filamentous and rod shaped bacteria were placed either in the genera Leptothrix or Leptotrichia. The confusion resulted from meager studies of many of these organisms, inadequate generic descriptions, and use of the ill-defined word "filamentous." Bergey's Manual of Determinative Bacteriology in 1948 stated, "the genus Leptotrichia Trevisan, 1879 is...

Isolation of an Organism Resembling Archromobacter Liquefaciens.

Although the type-species of the genus Achromobacter is A. liquefaciens (Eisenberg) Bergey et al., there is confusion over the authenticity of the type because the organism has been seldom isolated, verified, and deposited in typeculture collections. A taxonomic study of mesophilic Achromobacter species was reported by Rush (Ph.D. Thesis, Purdue lUniversity, Lafayette, Ind., 1947), but his type...

Extraction and Identification of Antibacterial Secondary Metabolites From Marine Streptomyces sp. VITBRK2

Actinomycetes were isolated from marine sediment samples collected from the east coast of Chennai, Tamil Nadu, India. Well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant Methicillin- resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococci (VRE). The potential isolate VITBRK2 was mass cultured for...
