“…Microbial communities within the gut of soil diplopods were previously demonstrated to differ from those found in the litter (Byzov et al 1996;Marialigeti et al 1985), but knowledge on their function is limited and it is not clear if these bacteria are specific for the diplopods' gut microbiota (Hopkin and Read 1992).…”

Bacterial clone libraries of the gut microbiota of nurtured and starved Cylindroiulus fulviceps specimens displayed the predominance of the phyla Bacteroidetes (55 and 37 %, respectively) and Proteobacteria (40 and 35 %, respectively) and a high similarity to bacteria previously detected in the intestinal tract of termites and beetles, which are known to harbor symbiotic bacteria essential for digestive activity. Bacterial isolates were dominated by Proteobacteria (74 %), followed by members of the phyla Actinobacteria, Firmicutes and Bacteroidetes. PCR-DGGE fingerprints of the gut samples showed that intestinal bacteria were affected by starvation, although the change was not significant.

“…Bacteria community also is place-specific for different parts of millipedes’ digestive tract and stays stable while millipedes are starving or change diet [10,11]. Some of actinobacteria in millipedes’ gut community produce antibiotics and enzymes against other microorganisms including species of the same community [12,13,14,15]. Bacterial species appeared as host-specific to different millipede species, so investigating gut microbiota of new millipede species is important for detecting new antibiotics produced by bacteria.…”

Antibiotic Activity of Actinobacteria from the Digestive Tract of Millipede Nedyopus dawydoffiae (Diplopoda)

Because of the spread of drug resistance, it is necessary to look for new antibiotics that are effective against pathogenic microorganisms. The purpose of this study was to analyse the species composition of actinobacteria isolated from the digestive tract of the millipedes Nedyopus dawydoffiae and to determine their antimicrobial properties. Species identification was carried out on the basis of the morphological and culture properties and the sequence of the 16S rRNA gene. Actinobacteria were grown in different liquid media. Antibiotic properties were determined against some Gram-positive and Gram-negative bacteria as well as fungi. Of the 15 isolated strains, 13 have antibiotic activity against Gram-positive bacteria (including methicillin-resistant Staphylococcus aureus—MRSA) and fungi, but there was no antibiotic activity against Gram-negative test strains Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853. It was established that antibiotic-producing actinobacteria belong to eight species of the genus Streptomyces. Depending on the nutrient medium, actinobacteria demonstrate different antimicrobial activities. As an example, S. hydrogenans shows that even strains selected in one population differ by the range of antimicrobial activity and the level of biosynthesis. Since the antibiotic production is considered as a feature for species competition in the microbiota community, the variability of antibiotic production among different strains of the same species is an adaptive characteristic for the competition in millipedes’ digestive tract community.

“…For the purpose of conservation it is important to define the levels of this relatively persistent compound which do not reduce the trophic activity of animals (Hopkin 1990). Such experiments can be conducted only under laboratory conditions, where dozens of primary food parameters can be manipulated (Dangerfield 1993;Roy, Joy 2009;Kulbachko, Didur 2012;Svyrydchenko, Brygadyrenko 2014) and observations are conducted in the microclimatic conditions of the experiment (Striganova 1972;Dangerfield, Milner 1993), the microbiological capacities of the substrate and the microflora composition of diplopod intestines (Márialigeti et al 1985;Zenova et al 1996;Kaneko 1999;Maraun et al 2003;Byzov 2006).…”
