“…Traditional biochemical identification of anaerobic bacteria comprises a multistep methodology typically culminating in the analysis of metabolic end‐products using gas–liquid chromatography (Burlage & Ellner, ; Perry, ). Biochemical assays allow the definitive identification of anaerobic bacteria, as opposed to just the presumptive identification using culture‐based approaches (Head & Ratnam, ).…”

“…The majority, including most key pathogenic species, grow optimally between 30 and 40°C, as summarized in Table . However, Brocklehurst and Lund () and Perry () isolated various strains of Clostridia from UK soils capable of significant growth at 10°C or lower. The optimum temperature for growth, sporulation and germination can vary between strains of the same species (Jensen et al, ) making behaviour and population dynamics in the soil difficult to predict (Evans et al, ).…”

The soil is a reservoir for various clostridial pathogens, with agricultural soils representing a major source of contamination for overlying crops and grazing livestock. Understanding the prevalence and behaviour of pathogens in these soils is fundamental to ascertaining and mitigating the risk of disease from agroecosystems. This article reviews research pertaining to the overall distribution and abundance of clostridial pathogens in the soil while identifying possible environmental and soil factors influencing their behaviour. Large‐scale soil screens have identified pathogens across the globe, although some Clostridium botulinum toxinotypes are more prevalent in certain geographic regions. Faecal inputs and organic waste amendments to the soil can elevate the levels of enteric clostridial pathogens in the soil and the subsequent disease risk, as highlighted by case–control studies. The ability of Clostridia to sporulate results in their long‐term persistence post‐introduction, increasing the time period for disease transmission. Regularly or permanently saturated soils may also enhance survival, or potentially facilitate the regrowth of some indigenous or introduced Clostridia. This is supported by the high prevalence of Clostridia in paddy soils, greater detection of pathogens in flooded soils, and the higher onset of some clostridial diseases in regions with poorly drained soils. Future research should elucidate soil types and environmental conditions which can enhance pathogen survival/regrowth. The adoption of molecular and sequencing technologies for future diagnostics can facilitate more sensitive detection and a higher resolution of pathogen typing, allowing a better understanding of pathogen population dynamics in farm soils and disease epidemiology. Highlights Understanding the behaviour of soil‐borne clostridial pathogens is key for disease management. Soil, environmental and management factors affecting pathogen survival/introduction are discussed. Soil waterlogging and application of organic soil amendments may increase the number of soil pathogens. More pathogen surveillance and standardisation of diagnostics to better understand behaviour is needed.

Twenty‐eight strains of pectolytic clostridia were isolated from sugar beet pulp silages. Seventeen non‐pigmented strains were presumed to be Clostridium acetobutylicum; the remaining 11 pigmented strains were similar to Cl. felsineum. The addition of molasses to sugar beet pulps favoured the growth of other bacteria, particularly lactic acid organisms, whereas pectolytic clostridia were only occasionally found. The pectolytic clostridia promoted the structure loss of simulated silages. The use of molasses in sugar beet pulp ensiling was suggested to prevent texture loss of the ensiled mass.
