The spread of pathogens in the environment due to human activities (pathogen pollution) may be involved in the emergence of many diseases in humans, livestock and wildlife. When manure from medicated livestock and urban effluents is spread onto agricultural land, both residues of antibiotics and bacteria carrying antibiotic resistance may be introduced into… (More)
The impact on wildlife health of the increase in the use of antimicrobial agents with the intensification of livestock production remains unknown. The composition, richness and prevalence of cloacal microflora as well as bacterial resistance to antibiotics in nestlings and full-grown Egyptian vultures Neophron percnopterus were assessed in four areas of… (More)
Antibiotic residues that may be present in carcasses of medicated livestock could pass to and greatly reduce scavenger wildlife populations. We surveyed residues of the quinolones enrofloxacin and its metabolite ciprofloxacin and other antibiotics (amoxicillin and oxytetracycline) in nestling griffon Gyps fulvus, cinereous Aegypius monachus and Egyptian… (More)
An unusual case of hepatic hydatidosis complicated by transphrenic migration of the hydatid cyst passing through the right hemidiaphragm, and penetrating the inferior pulmonary lobe causing a bronchial fistula, is presented. The computed tomographic (CT) study permitted the correct preoperative diagnosis.
The August, 1991 eruption of Mt. Hudson (Chile) deposited ash across southern Argentina and contributed to the deaths of thousands of grazing sheep. Early ash analysis revealed high levels of fluoride, a potential ash constituent toxic to humans and animals. In order to evaluate fluorosis as the cause of sheep deaths and to examine the possibility that… (More)
Stabled livestock reared in housed conditions are often subjected to intensive treatments with veterinary drug, which residues may be present in livestock meat ingested by scavengers, but nothing is known about their presence in eggs of wild birds and their potential detrimental effects on breeding success. We searched for residues of veterinary drugs and… (More)
Attempting to obtain a classifier or a model from datasets could be a cumbersome task, specifically, when using datasets of high dimensionality. The larger the amount of features the higher the complexity of the problem, and the larger the time that is expended in generating the outcome -the classifier or the model-. Feature selection has been proved as a… (More)
We report a case of obstructive jaundice in which the tract of a surgically placed T-tube was used as a route for easy access to stent a neoplastic stenosis of the common bile duct.
In the recent literature on dark energy (DE) model building we have learnt that cosmologies with variable cosmological parameters can mimic more traditional DE pictures exclusively based on scalar fields (e.g. quintessence and phantom). In a previous work we have illustrated this situation within the context of a renormalization group running cosmological… (More)
