“…However, rough dog’s tail grass is found worldwide and is not reported to cause illness [ 19 ]. Lancaster et al [ 6 ] found that rough dog’s tail grass harvested from an affected property and fed to cattle on two occasions resulted in no ill effects. The first feeding trial was conducted in Tasmania with calves and remains unpublished (cited in [ 6 ]), while the second was conducted in Victoria in 2003.…”

The first feeding trial was conducted in Tasmania with calves and remains unpublished (cited in [ 6 ]), while the second was conducted in Victoria in 2003. In the latter, rough dog’s tail grass was harvested from six properties that had experienced ABLD in the previous two years.…”

“…It has been a recognized condition since the 1950s though documented evidence from the early years is non-existent [ 4 ]. Lancaster et al [ 6 ] collated findings from 15 reports not found in general circulation. Further documented ABLD events are contained in case reports, conference reports or newsletters shared between practicing veterinarians in relevant Australian states ( Table 1 ) [ 3 , 6 , 7 , 8 , 9 ].…”

Further documented ABLD events are contained in case reports, conference reports or newsletters shared between practicing veterinarians in relevant Australian states ( Table 1 ) [ 3 , 6 , 7 , 8 , 9 ]. Accordingly, documented ABLD cases predominantly report clinical observations, findings of clinical and anatomical pathology, and suggestions that ABLD is caused by an unknown toxin.…”

“…In addition to clinical findings, some case reports include limited epidemiological observations such as environmental and weather conditions, seasonality, and the presence or absence of plants of interest [ 7 ]. Interestingly, almost all reports have recorded the presence of senescent rough dog’s tail grass ( Cynosurus echinatus ) in the suspected paddock [ 6 ]. Rough dog’s tail grass was also present in the two reports of mycotoxicosis in sheep [ 1 , 2 ].…”

Acute bovine liver disease (ABLD) is a hepatotoxicity principally of cattle which occurs in southern regions of Australia. Severely affected animals undergo rapid clinical progression with mortalities often occurring prior to the recognition of clinical signs. Less severely affected animals develop photosensitization and a proportion can develop liver failure. The characteristic histopathological lesion in acute fatal cases is severe, with acute necrosis of periportal hepatocytes with hemorrhage into the necrotic areas. Currently there are a small number of toxins that are known to cause periportal necrosis in cattle, although none of these have so far been linked to ABLD. Furthermore, ABLD has frequently been associated with the presence of rough dog’s tail grass (Cynosurus echinatus) and Drechslera spp. fungi in the pasture system, but it is currently unknown if these are etiological factors. Much of the knowledge about ABLD is contained within case reports, with very little experimental research investigating the specific cause(s). This review provides an overview of the current and most recently published knowledge of ABLD. It also draws on wider research and unpublished reports to suggest possible fungi and mycotoxins that may give rise to ABLD.

Clinical and pathologic features of acute bovine liver disease in Australia

et al. 2021

Acute bovine liver disease (ABLD) is a sporadic hepatic disease affecting cattle in southern Australia, characterized histologically by striking periportal hepatocellular necrosis. The cause of ABLD is unknown; however, the seasonality and acute presentation of outbreaks suggest mycotoxin involvement. We describe here the clinical and pathologic findings of ABLD in 45 naturally affected cattle from 13 outbreaks occurring from 2010 to 2019 in Victoria, Australia. Outbreaks occurred in herds located along the southern coastal plain of Victoria and were observed most frequently in lactating dairy cattle. Clinical signs commonly included a combination of mild photosensitization, progressive neurologic signs, and hypogalactia, which preceded death by ≤ 48 h. All affected animals had marked elevations in activities of glutamate dehydrogenase, aspartate aminotransferase, and gamma-glutamyl transferase. At autopsy, the most common lesions were serosal petechiae and/or gastrointestinal hemorrhage, and hepatomegaly with a pronounced hepatic reticular pattern. The principal histologic lesion was widespread—severe periportal hepatocellular coagulative necrosis and erythrocyte pooling—which often extended to massive necrosis. Lesions in other organs were uncommon. Our study of ABLD suggests involvement of a potent hepatotoxin that is either directly cytopathic or requires bioactivation by periportal-specific enzymes.
