Abstracts:
In the semiarid region of northeastern Brazil, Tephrosia cinerea causes periacinar hepatic fibrosis in sheep with severe ascites and, occasionally, nervous signs. Sixteen sheep from six outbreaks of T. cinerea poisoning were studied. All sheep had histologic lesion of periacinar fibrosis and six showed, in the brain, vacuolization (spongy degeneration) of the white matter and junction between grey and white matter and presence of Alzheimer type II astrocytes in the grey matter. The disease was produced experimentally in two sheep, that presented porto-sistemic shunts and similar histologic lesions as those observed in the spontaneous cases. Immunohistochemistry revealed weak labelling with anti-GFAP antibodies suggesting a degenerative alteration of astrocytes with accumulation of dense bodies and reduction of
the GFAP. There was strong labelling with anti-S100 antibodies suggesting cellular reactivity with proliferation of mitochondria and endoplasmatic reticulum. Such alterations are characteristic of the effects caused by ammonia on the astrocytes. It is concluded that in poisoning by T. cinerea nervous signs due to hepatic encephalopathy occur in some sheep. |

Many Teratosphaeria species are associated with leaf diseases on Eucalyptus spp. (Myrtaceae). However, only a few of these are major pathogens that cause serious losses, particularly to plantation forestry globally. Several species in the Teratosphaeraceae and Mycosphaereaceae species are known to occur in Uruguay where they cause leaf and shoot diseases on Eucalyptus plantations, but most are of minor importance. However, two species have had a serious negative impact on the performance of certain Eucalyptus species. Since its first detection in 2007, Teratosphaeria nubilosa has eliminated Eucalyptus globulus from the available species for pulpwood production. Species substitution has been the main management tool for this pathogen resulting in negative consequences such as limited access to external markets. More recently, in 2011, Teratosphaeria pseudoeucalypti was reported causing leaf blight that has resulted in severe defoliation and death of established Eucalyptus camaldulensis, E. tereticornis, and their hybrids. This pathogen was first described in Australia in 2010 and simultaneously reported in Argentina, Brazil and Uruguay four years later. This disease is a serious threat to Uruguayan plantations and has already imparted a significant social and economic impact in the country where it has damaged urban parks and plantations used for shelter and shade for livestock production. These two examples of serious diseases caused by Teratosphaeria spp. have highlighted that accidentally introduced non-native pathogens can have in a country. They have also raised concerns that such pathogens could threaten the many native Myrtaceae found natural forest ecosystems in Uruguay.
