ABSTRACT. Three outbreaks of poisoning by Portulaca oleracea were reported in sheep and goats in Northeast Brazil. In the first outbreak, 8 out of 20 sheep were affected and later died. In the second outbreak, three goats and one sheep died out of a flock of 30 animals that included both species. In the third outbreak, two out of 19 sheep were affected, and they recovered after a treatment of 2% methylene blue at a dose of 4 mg/kg body weight. In the first and
second outbreaks, the animals ingested P. oleracea after it was cut and offered in feeders. In the third outbreak, the flock was grazing in an area that had been invaded by the plant. To determine the toxicity, P. oleracea was administered experimentally at a dose of 80g/kg of body weight to seven sheep, weighing 19-30 kg. One control sheep received green grass. One to four hours after P. oleracea ingestion, the animals showed clinical signs of poisoning characterized by cyanotic mucous membranes, bloat, ruminal pH of 8-9, pollakiuria, aerophagia,involuntary movements of the upper lip, apathy, tachypnea and tachycardia. Five animals
recovered, including one that was treated with 1% methylene blue, and two animals died. During necropsy, the mucous membranes were brownish, and the blood was dark brown. Diphenylamine tests of the plant and of rumen contents were positive for nitrates. Positive results for nitrates were also found in 24 samples of P. oleracea that were collected in different places in the states of Pernambuco and Paraíba. We conclude that P. oleracea accumulates nitrates at toxic levels and may cause poisoning in sheep and goats. MenosABSTRACT.

Rhipicephalus microplus is responsible for major economic losses in cattle ranching in Brazil, and the development of multiple acaricide resistance is a major concern to control this ectoparasite. To determine the resistance of R. microplus to acaricides in 26 ranches in the semi-arid region of Paraíba State, Brazil, larval assays were performed with cypermethrin, chlorpyriphos, amitraz, ivermectin and fipronil and resistance was observed in all locations. The frequency of populations resistant to cypermethrin, chlorpyriphos, amitraz and ivermectin was, respectively, 96 %, 72 %, 83 % and 92 % while none was resistant to fipronil. Resistance to one, two, three and four acaricides was recorded, respectively, in 4 %, 15 %, 31 % and 50 % of the farms. Errors in the control management of R. microplus determined the development of resistance to acaricides in all evaluated properties pointing towards development of new strategies for its control. In order to control multiple acaricide-resistant cattle tick populations in this area it is recommended to apply suppressive treatments with fipronil and/ or fluazuron.
