“…Similar to previous findings, in this survey, more than half of the veterinary respondents rated secondary (hepatogeneous) photosensitisation as the most common type of photosensitisation, further supporting previous evidence that hepatogeneous photosensitising plants or agents are significantly more common than those containing primary photocytotoxic compounds 1,7 . Reasons for this commonality of presentation are that toxic plants know to contain hepatotoxic agents are found more frequently in nature than those containing primary sensitisers 8,9 . Equally, the least common type of photosensitisation, the congenital type (II) that requires specific genome mutations, is very uncommon in livestock 10,11 .…”

“…Australia has experienced outbreaks of primary photosensitisation that are specific and unique to this region. One examples is photosensitisation caused by the pasture legume Biserrula pelecinus , although a native of the southern Mediterranean, it is exclusively used as a livestock fodder only in Australia [102] where this pasture legume is now clearly identified as causing outbreaks of primary photosensitisation [37,38]. Outbreaks that have never been recorded in its native domains where it grows as a native only in mixed swards.…”

“…Previously, no objective photosensitisation scoring protocol had been defined in literature resulting in prevalence and severity of affected animals to be hard to compare between outbreaks. Recently, a semi-objective photosensitisation grading system has been developed for sheep to address this issue [37]. The use of such a grading system in future outbreaks will allow better correlation between access to potentially photosensitising pastures or feedstuffs with more accurate determination of the timing of onset of outbreaks, as well as a more definitive and consistent identification of the severity of the condition.…”
