In this work, we describe the ability of living cells of Entamoeba histolytica to hydrolyze extracellular ATP. In these intact parasites, whose viability was determined by motility and by the eosin… (More)
Bovine mastitis is an important and complex disease responsible for economic losses in the dairy industry. Biotype II strains of the green alga Prototheca zopfii can be involved, most often resulting… (More)
OBJECTIVES
Bovine mammary protothecosis is a serious pathology that entails high economic losses in the dairy industry. The disease, the frequency of which has recently been increasing worldwide, is… (More)
The hydroalcoholic extract (HAE) of Ageratum conyzoides leaves was studied for its antiinflammatory effect on subacute (cotton pellet-induced granuloma) and chronic (formaldehyde-induced arthritis)… (More)
Serologic evidence for canine distemper virus (CDV) has been described in grey wolves but, to our knowledge, virus strains circulating in wolves have not been characterized genetically. The emergence… (More)
Among the current treatment strategies for the peptic ulcer patient with Helicobacter pylori infection, the method of choice is triple therapy based on the concurrent use of proton inhibitors and two… (More)
An epidemiological study was conducted on a population attending outpatient clinics in Manaus, Amazon, Brazil to determine the prevalences of infection by the Entamoeba histolytica/E. dispar complex… (More)
Among the many initiating events that lead to apoptosis or programmed cell death, loss of contact between the cell and the extracellular matrix has been extensively studied. Adhesion-related… (More)
It is widely accepted that a prolonged ouabain blockade of the Na(+),K(+)-ATPase makes cells detach from each other and from the substrate, leading to their death and that cellular resistance to… (More)
Since it is known that Entamoeba dispar is non-pathogenic and morphologically similar to E. histolytica, there are many targets used in PCR for differentiating these species. However, obtaining high… (More)
