Epidemiological aspects and clinical signs of natural poisoning by Ipomoea asarifolia in buffaloes are described. The poisoning was diagnosed in four buffaloes on three different farms, in the County of Cachoeira do Arari, Marajó Island, Pará, and occurred in November-December, a period of drought and severe pasture shortage. The clinical signs were of the central nervous system, as unsteady gait, hypermetria, severe muscular tremors, falling down in unusual positions, nystagmus and marked excitement, signs that turned more severe after movement. Based on the epidemic aspects, clinical signs and absence of histopatological changes, poisoning by Ipomoea asarifolia was diagnosed.

To determine plant poisonings occurring on Marajo Island, state of Pará, northern Brazil, 7 farms were visited. All farms had native pastures with low forage availability severely infected by Ipomoea asarifolia. In 5 farms poisoning in sheep by the plant was reported. The disease occurs mainly during the dry period and lambs are more frequently affected than adult sheep. Sheep with clinical signs were observed in 2 farms. In 4 establishments farmers reported the occurrence of I. asarifolia poisoning in cattle. In one farm affected cattle were observed during two visits, one during the dry season and another at the start of the raining season. Deaths are observed mainly in calves. In both species the poisoning occurs every year with variable morbidity and low mortality. One bovine and one sheep with severe clinical signs were euthanized and post-mortem examination was performed. No gross or histologic significant lesions were observed. In all farms buffaloes were raised together with cattle and sheep, and in 3 farms goats were also raised. None of the farmers reported the intoxication in these species.

Intoxicações experimental e natural por Ipomoea asarifolia (Convolvulaceae) em búfalos e outros ruminantes

Ipomoea asarifolia R. et Schult. is a plant responsible for occasional outbreaks of poisoning in cattle, sheep and goats. Its oral administration to cattle and buffalos showed that the buffalo is as susceptible as cattle. One to 4 daily doses of 10-20g/kg caused similar symptoms in both species, as incoordination, muscular twiching and swaying of the head and anterior part of the body (pendular movement). In buffaloes the signs of incoordination were observed to a smaller extent. There is no report yet on natural poisoning by I. asarifolia in buffaloes, possibly because cases are not being noticed.
