Thus, of the major orders, Lactobacillales, Fusobacteriales, Burkholderiales, and Campylobacterales rRNA genes were better amplified by primers spanning the V1-V3 region, whereas Clostridiales, Actinomycetales
, Bacilliales, and Neisseriales were better represented by primers spanning the V6-V8 region.
The order Actinomycetales
also includes the genera of Actinomyces, Corynebacterium, Mycobacterium, Nocardiaceae and Streptomyces.
This 65-entry reference describes the cell wall in terms of its infrastructure and surface proteins, the Streptococcus groups (including A, B, C, G, pneumoniae, enterococci, oral streptococci and lactococci), Staphylococcus (including cell interactions, animal models of experimental Staphylococcus aureus infection and antibiotic resistance), the Listeriae, spore-forming pathogens and gram-positive members of the Actinomycetales
, and antibiotic heavy metal resistance mechanisms.
Myrica grows in symbiotic association with the nitrogen-fixing endophyte Frankia (Actinomycetales
), and the presence of Myrica has been shown to increase soil nitrogen levels (Simpson et al.
Most metabolites of bacterial origin come from one group, namely the Gram-positive soil bacteria of the order Actinomycetales
. Although these bacteria continue to be studied extensively, it is clear that the rate of discovery of novel metabolites from this source is decreasing.
In fact, Brevibacterium is a unique genus of the Brevibacteriacea family located in the suborder Micrococcineae, order Actinomycetales
, and class Actinobacteria.
Spinosad is a bio-insecticide produced from the bacterium Saccharopolyspora spinosa Mertz and Yao (Actinomycetales
: Pseudonocardiaceae) that is increasingly used against stored grain pests (Hertlein et al.
 The genus Nocardia belongs to the order Actinomycetales
, a group of aerobic, Gram-positive filamentous bacteria.
Studies on the ecology of actinomycetes in an agricultural soil amended with organic residues: identification of the dominant groups of Actinomycetales
. World J.
Several clinically significant antibiotics as well as widely used drugs against common diseases have been derived from this unique genus affiliated with the order Actinomycetales
They are closely related to the aerobic Nocardia spp., and classified as higher prokaryotic bacteria as well as the Mycobacteriacae family, which belongs to the same order Actinomycetales
. Numerous Actinomyces species may cause disease in human.
