Pyrrolizidine alkaloid poisoning of sheep in New South Wales

Abstract: Pyrrolizidine alkaloid poisoning of sheep in New South Wales was reviewed, based on the records of the New South Wales Department of Agriculture's Regional Veterinary Laboratories. The plant species causing significant mortalities were Echium plantagineum and Heliotropium europaeum. The syndrome of hepatogenous chronic copper poisoning was more frequently diagnosed than primary pyrrolizidine alkaloid poisoning, particularly when grazing E. plantagineum. The data indicated that adult crossbred ewes were the mos… Show more

“…About half of these PAs formed are toxic. Therefore, The PA-containing plants are poisonous to livestock and wildlife and have caused tremendous livestock loss (Arzt and Mount, 1999;de Lanux-Van Gorder, 2000;Fletcher et al, 2009;Fowler, 1968;Knight et al, 1984;Seaman, 1978Seaman, , 1987Sharrock, 1969;van der Watt et al, 1972;Wiltjer and Walker, 1974). PAs are also the leading plant toxins associated with disease in humans through contamination of staple foods, honey, milk, herbal teas and herbal medicines (Arseculeratne et al, 1981(Arseculeratne et al, , 1985Bach et al, 1989;Bah et al, 1994;Culvenor et al, 1981;Deinzer et al, 1977;Dickinson et al, 1976;Edgar et al, 1992Edgar et al, , 2002Huxtable et al, 1986;Jago, 1969;Kumana et al, 1983Kumana et al, : 1985Mattocks, 1980;Ridker et al, 1985;Roitman, 1981;Steenkamp et al, 2000;White et al, 1984;Zhao et al, 1989).…”

“…Na Austrália, S. madagascariensis esteve envolvido em um surto de intoxicação por pirrolizidinas em ovinos (Seaman 1987). Em algumas regiões da Austrália, a ingestão de Echium plantagineum e Heliotropium europaeum é considerada a maior causa de perdas de ovinos pela ingestão de plantas contendo pirrolizidinas (St George-Grambauer & Rac 1962, Bull et al 1968, Seaman 1985, 1987. Intoxicação por em ovinos por Senecio spp também tem sido descrita na África do Sul (Kellerman et al 1988) e Nova Zelândia (Bull et al 1968).…”

“…Os APs em ovinos podem causar intoxicação aguda com necrose centrolobular e intoxicação crônica com ϐibrose hepática, fotossensibilização, encefalopatia hepática e edemas, ou intoxicação crônica por cobre, hemólise, icterícia e hemoglobinúria (Seaman 1987, Ilha et al 2001, Kellerman et al 2005, Nobre et al 2005, Grecco et al 2011. No Brasil, surtos de intoxicação por Senecio spp em ovinos são raros, apesar de frequentes em outras partes do mundo (Bull et al1968, Forsyth 1979, Kellerman et al 2005.…”
