“…The concentrations of E. coli measured for the manure fractions were also corresponded with the previous studies in which the either fresh or the (shadow) dried solid manures reported (Blaustein et al, 2015;Guber et al, 2013;Sepehrnia et al, 2014Sepehrnia et al, , 2017Sepehrnia et al, , 2018Unc and Goss, 2004). Unc and Goss (2004) and Kabelitza et al (2020) also reported that cultivable bacteria are commonly about 10 9 -10 10 CFU g À1 in fresh solid manures (i.e., cow, poultry, pig). Blaustein et al (2015) observed E. coli constituted over half of total coliforms, and the total contents of E. coli and enterococci in the synthesized solid manure were similar (2.62 AE 0.76 Â 10 6 CFU ml À1 ).…”

Bacteria transport through soil is a complex process particularly when the cells are released from solid manures and co-transported with particles. This study focuses on understanding of the Escherichia coli release from different particle fractions (0.25-, 0.5-, 1-, and 2-mm) of solid manure and evaluating different influent boundary conditions during cell release from manure and when a solid manure is applied to the soil. The 0.25-mm and 2-mm particle sizes resulted a greater cell release compared to 0.5-mm and 1-mm fractions (p < 0.05). The shape and magnitude of the cell release curves (CRCs) from the original manure bulk were mainly influenced by the two 0.25-mm and 2-mm fractions, respectively. The arithmetic mean for normalizing the CRCs and the time variablebased normalized CRCs for the manure-treated soil were the robust variables in evaluation of the experimental data. However, a single maximum bacteria concentration could provide the realistic dataset for the modeling process. Evaluation of the root-mean-squared-error and Akaike criterion showed that the two-and threeparametric models are recommended for simulating the cell release from solid manure in comparison with one parametric models. This study also suggests considering separate microbial release evaluations, with regards to influent concentration, for manure and manure-treated soils to propose best management practices for controlling bacteria pollution. Further research will reveal the key roles of different woody components and soluble material ratios for the various solid manures in bacteria release.

“…This dust may stay airborne for several days and during this time may get transported over several hundred kilometres, depending on atmospheric conditions (Thiel et al, 2020;Faust et al, 2021). Poultry manure is particularly prone to aerosolization due to its high dry-matter content (Kabelitz et al, 2020;Thiel et al, 2020;Kabelitz et al, 2021) and therefore, its application for fertilization of agricultural fields likely contributes to the airborne dispersal of chicken-associated C. difficile over long distances. Aerosolized C. difficile is considered a potential source of human infection when inhaled (Best et al, 2010), similar to other enteric pathogens (Jahne et al, 2015).…”

During a field experiment applying broiler manure for fertilization of agricultural land, we detected viable Clostridioides (also known as Clostridium) difficile in broiler faeces, manure, dust and fertilized soil. A large diversity of toxigenic C. difficile isolates was recovered, including PCR ribotypes common from human disease. Genomic relatedness of C. difficile isolates from dust and from soil, recovered more than 2 years after fertilization, traced their origins to the specific chicken farm that had delivered the manure. We present evidence of long-term contamination of agricultural soil with manure-derived C. difficile and demonstrate the potential for airborne dispersal of C. difficile through dust emissions during manure application. Clostridioides genome sequences virtually identical to those from manure had been recovered from chicken meat and from human infections in previous studies, suggesting broiler-associated C. difficile are capable of zoonotic transmission.
