For the last 150 years many studies have shown the importance of earthworms for plant growth, but the exact mechanisms involved in the process are still poorly understood. Many important functions required for plant growth can be performed by soil microbes in the rhizosphere. To investigate earthworm influence on the rhizosphere microbial community, we performed a macrocosm experiment with and without Pontoscolex corethrurus (EW+ and EW?, respectively) and followed various soil and rhizosphere processes for 217 days with sugarcane. In EW+ treatments, N2O concentrations belowground (15 cm depth) and relative abundances of nitrous oxide genes (nosZ) were higher in bulk soil and rhizosphere, suggesting that soil microbes were able to consume earthworm-induced N2O. Shotgun sequencing (total DNA) revealed that around 70 microbial functions in bulk soil and rhizosphere differed between EW+ and EW? treatments. Overall, genes indicative of biosynthetic pathways and cell proliferation processes were enriched in EW+ treatments, suggesting a positive influence of worms. In EW+ rhizosphere, functions associated with plant-microbe symbiosis were enriched relative to EW? rhizosphere. Ecological networks inferred from the datasets revealed decreased niche diversification and increased keystone functions as an earthworm-derived effect. Plant biomass was improved in EW+ and worm population proliferated. |

The artisanal Coalho cheese is one of the most consumed dairy products in some regions of Brazil, especially in the Northeastern. Because it is minimally ripened, it should be produced using heat-treated milk, however, its manufacture commonly uses raw milk. Reports of contamination of Coalho cheese with pathogenic bacteria are increasing, including Mycobacterium spp. Non-tuberculous mycobacteria (NTM) are emerging pathogens that cause infections in humans. This study describes the identification of viable NTM in artisanal Coalho cheese in the State of Paraíba, Northeastern, Brazil. On hundred samples of artisanal Coalho cheese, produced without sanitary inspection, were collected at street markets in the regions of Borborema, Agreste and Mata, and cultured in Stonebrink medium. Isolates were analyzed by PCR for hsp65 of Mycobacterium spp. and the DNA amplicons were sequenced. The resulting sequences were submitted to identity search by Blastn (NCBI). Colonies were isolated in 5/100 (5%) samples of Coalho cheese, which were positive in the PCR for hsp65. The resulting DNA consensus sequences showed similarity to hsp65 from Mycobacterium fortuitum (100% identity), Mycobacterium novocastrense (99% identity), Bifidobacterium crudilactis (98% identity), Kocuria rhizophila (98% identity) and Kocuria palustris (91% identity).The consumption of artisanal Coalho cheese from street markets represents a risk for human health, due to the possibility of transmission of non-tuberculous mycobacteria and other actinobacteria potentially pathogenic. This study reinforces the need for the establishment of public policies to prevent the commercialization of Coalho cheese, produced without sanitary inspection.
