ABSTRACT.
The aim of this work was to describe the epidemiological, clinical and pathological aspects of spontaneous poisoning by Merremia macrocalyx in cattle in the Pernambuco state, northeastern Brazil, and to experimentally replicate the poisoning by this plant. To determine the occurrence of poisonings, 30 farms were visited in six municipalities at the Forest Zone of Pernambuco. The plant was found in nine farms, in which history of plant poisoning in cattle, and occasionally in sheep were also reported. Three outbreaks of spontaneous poisonings in cattle were studied. To replicate the disease experimentally, two steers received a single dose of 60g/kg and two steers received 80g/kg of the fresh leaves of M. macrocalyx in the trough for spontaneous ingestion. Two steers were also used as a control group. The main clinical signs observed in spontaneous cases consisted of restlessness, bloat, polyuria, diarrhea, and death within 48 to 72 hours after the onset of clinical signs. Cattle experimentally poisoned presented similar clinical signs to those observed in spontaneous cases. Gross lesions consisted of dryness and impaction of the rumen, omasum and reticulum contents. Abomasal content was fluid, the mucosa was hyperemic, with swollen folds and multiple ulcers. Similar lesions were observed in duodenum mucosae. Histologically, lesions observed in the abomasum and duodenum mucosa consisted of necrosis, hemorrhage and inflammatory infiltration of neutrophils and lymphocytes. The wide distribution and palatability of this plant, associated with the high sensitivity of the bovine species verified in this experiment, highlight the importance of this plant in spontaneous cases of poisoning in cattle.
RESUMO.
O objetivo deste trabalho é descrever os aspectos epidemiológicos, clínicos e patológicos da intoxicação espontânea por Merremia macrocalyx em bovinos de Pernambuco, nordeste do Brasil e reproduzir experimentalmente a intoxicação por esta planta. Para determinar a ocorrência das intoxicações, foram visitadas 30 propriedades em seis municípios na Zona da Mata de Pernambuco. A planta foi encontrada em nove fazendas onde também haviam históricos de intoxicações em bovinos e ocasionalmente em ovinos. Três surtos de intoxicações espontâneas em bovinos foram estudados e para reproduzir experimentalmente a doença, dois novilhos receberam doses únicas de 60g/kg e dois novilhos receberam 80g/kg de folhas frescas de M. Macrocalyx para consumo espontâneo no cocho. Dois novilhos foram utilizados como grupo controle. Os principais sinais clínicos observados na intoxicação espontânea consistiram em agitação, timpanismo, poliúria, diarreia e morte dentro de 48 a 72 horas após a observação dos primeiros sinais clínicos. Os bovinos intoxicados experimentalmente apresentaram sinais clínicos semelhantes aos observados nos casos espontâneos. À necropsia as lesões consistiam em compactação e ressecamento dos conteúdos do rúmen, omaso e retículo. O conteúdo do abomaso estava fluido, notava-se hiperemia das mucosas, as pregas estavam edemaciadas e continham múltiplas úlceras. Lesões semelhantes também foram observadas na mucosa do duodeno. Histologicamente, as lesões observadas na mucosa do abomaso e do duodeno consistiam em necrose, hemorragia e infiltrado inflamatório neutrofílico e linfocítico. A ampla distribuição de Merremia macrocalyx na região estudada e a boa palatabilidade associada à alta sensibilidade da espécie bovina verificada neste experimento, reforça a importância desta planta em casos espontâneos de intoxicação em bovinos.

ABSTRACT.
A method is described for obtaining interspecific hybrids between commercial lines of Lotus uliginosus Schkuhr and Lotus corniculatus L. Hybridization was possible between these species using embryo rescue. Two strategies were used to confirm 40 F1 hybrids, that is, flow cytometry and microsatellite simple sequence repeats (SSRs). The L. uliginosus and L. corniculatus parents have significantly different genome size (2.5 ± 0.02 and 2.22 ± 0.02 pg, respectively) and the offspring from the cross had intermediate values. Two SSR primers were polymorphic between the genotypes tested, TM1150 and EH380069. Maternal effect was detected in L. uliginosus genotypes, as determined by greater frequency of F1 hybrids. Recombinant traits were observed in the F1 hybrid progeny. Ninety F1 hybrids resulting from L. uliginosus × L. corniculatus crosses showed different levels of fertility in the polycross; <3% F1 plants produced more than 1000 seeds without embryo rescue while 10% of plants did not flower the first year. The F1 hybrid plants grown under greenhouse conditions exhibited shoot phenotypes similar to L. uliginosus (maternal) whereas F2 phenotypes were similar to L. corniculatus (paternal) in field trials. Rhizome presence was observed in 60% of F2 hybrid plants. The diameters of the root crowns of these plants, however, were similar to that of L. corniculatus.
