The Destruction of Mycobacteria

Treatment alternatives of slaughterhouse wastes, and their effect on the inactivation of different pathogens: A review

“…The authors concluded that as the majority of solid dung heaps do not reach this high a temperature, composted manure cannot necessarily be considered safe. These findings appear to be contradictory of the results of related Mycobacterium studies, and of the findings of pasteurization studies by Croshaw et al (1971).…”

“…However, actual infections in humans are rare, because of control measures put in place. Studies by Croshaw et al (1971) showed that M. bovis was destroyed by the pasteurization of milk at 71.7°C for 15 sec, and at 62.8°C for 30 min.…”

Activity of biocides against mycobacteria

“…They include aldehydes, alcohols, bisbiguanides, halogenreleasing agents (HRAs), isothazolones, mercurials, organic acids and esters, phenolics and quaternary ammonium compounds (QACs), together with gaseous agents such as ethylene oxide. Croshaw (1971) listed ampholytic surfactants (e.g. Their anti-mycobacterial properties are summarized in Table 2.…”

“…Treatment of Myco. Croshaw (1971) quotes the vork of T. €1. EB also disorganizes these layers 96s A. D. RUSSELL and, in addition, can induce the formation of bacterial ghosts without the dissolution of the peptidoglycan (Rastogi t t rrl.…”

Bactericidal effect of chlorine on Mycobacterium paratuberculosis in drinking water

“…Early studies have shown that mycobacteria are more resistant to biocides than other nonsporulating bacteria (reviewed by Croshaw 1971) and recent work has shown that some species are particularly resistant. Most waters that are intended for human usage are treated with chlorine or chlorine compounds before they are piped to the consumer (Collins et al .…”
