Abstract: Tuberculosis is a major source of global mortality caused by infection, partly because of a tremendous ongoing burden of undiagnosed disease. Improved diagnostic technology may play an increasingly crucial part in global efforts to end tuberculosis, but the ability of diagnostic tests to curb tuberculosis transmission is dependent on multiple factors, including the time taken by a patient to seek health care, the patient's symptoms, and the patterns of transmission before diagnosis. Novel diagnostic assays for… Show more

“…Positive values signify that nuclear test- derived 14 C was incorporated into the SOC fraction (young apparent 14 C age). Negative values indicate that soil fraction carbon exchange with the atmosphere has been slow and that significant radioactive decay has occurred (old apparent 14 C age) 35 . …”

“…Selective preservation of certain SOC fractions with higher stability 35 could theoretically explain the preservation of SOC that has been buried for several decades. The labile fractions of SOC would then be mineralised leaving the most stable fraction as buried SOC.…”

“…Organic matter derived from plant and microbial debris, mucilages and extracellular polymeric substances in general (such as cell walls and biofilms) are likely to influence the soil environment, potentially bioengineering local soil chemistry and properties to provide conditions conducive for specific needs (Oades 1984; Benizri et al 2007; Lehmann and Kleber 2015). Polysaccharides have long been implicated in soil particle adhesion and aggregation but have not been dissected in detail due to the challenging nature of their diversity and structural complexities (Cheshire and Hayes 1990; Oades 1993).…”

“…Emerging evidence from advanced isotopic and spectroscopic studies has recently shown that physicochemical and biological influences of the surrounding environment, rather than the recalcitrance of organic matter, play a primary role in soil organic carbon (SOC) stabilization 1, 2 . Interaction with the mineral phase, particularly iron (Fe) and aluminum (Al) oxides, is a major mechanism that prevents microbial decomposition and thus stabilizes organic C in mineral soils for centuries or millennia 35 .…”
