| One hundred and eighty species belonging to 41 families inhabiting the Salado River Basin of the province of Buenos Aires (Argentina) were previously reported to be toxic for cattle. The purpose of this study was to provide a tool to distinguish the taxa when the plant material is desintegrated. In this way, an approach to the identification of these taxa through leaf epidermal features (anticlinal epidermal cell wall patterns, cuticular ornamentation, stomata, and hair types) is performed. A key to the 180 species as well as illustrations of diagnostic characters are given. |

| ABSTRACT: In Brazil sodium monofluoroacetate (MFA) containing plants are represented by 16 species that belong to three principle genera: Palicourea ( Rubiaceae ), Amorimia ( Malpighiaceae ), and Tanaecium ( Bignoniaceae ). These plants can cause acute cardiac failure often referred to as sudden death syndrome. The objective of this paper was to determine if N. stannea contains MFA and to report the clinical signs and pathology of cattle experimentally poisoned by this plant. MFA was detected in all N. stannea plant parts except mature leaves. Niedenzuella stannea was dosed to cattle at single doses of 15-30g kg-1 bw. Clinical signs and pathology observed were similar to those reported by other MFA-containing plants. Animals showed marked tachycardia,... |

| ABSTRACT: The objective of this study was to describe the epidemiological, clinical, and pathological aspects of Palicourea aeneofusca poisoning in cattle in the region of Pernambuco, Brazil and to determine if it is possible to induce food aversion by P. aeneofusca poisoning in cattle raised under extensive management conditions. To determine the occurrence of poisoning, 30 properties were visited in five municipalities of the region of Pernambuco. Three outbreaks of poisoning of cattle were monitored. To induce conditioned food aversion by the consumption of P. aeneofusca, 12 animals were randomly distributed into two groups of six animals each. Cattle were weighed and received green P. aeneofusca leaves in their trough at a dose of 35mg kg-1 body weight... |
