AbstractThe aim of this study was to evaluate the role of the brown rat (Rattus norvegicus) as a potential reservoir of zoonotic parasites in an urban area of Argentina. A parasitological survey in 40 brown rats trapped in a shantytown of Buenos Aires City was carried out. 97.5 % of the analyzed rats were parasitized with at least one of the 12 species of helminth or protozoan species recorded. Among the species identified, Hymenolepis nana is recognized as one of the most common human helminthes parasites. The average number of parasite species was higher in males than females rats, and in the last case, a direct relationship between parasite species richness and host’s body size was recorded. Variations in endoparasite community throughout the year seasons were recorded, probably related to environmental factors, which limits the performance of the life cycle of different parasite species. The presence of zoonotic endoparasites confirms R. norvegicus as a reservoir for different types of pathologies, which, therefore, represents a risk to the public health in an overcrowded urban area.

AbstractIn comparison to some illegal enterprises whose operations generate decisive moral rejection on the part of the public, vehicle theft remains an illicit underground activity that citizens largely tolerate or even exploit. In the province of Buenos Aires, the persistence, depth and breadth of transactions related to this black market cannot be explained without referring to the role of the state police. This article uses a theoretical approach to illegal police protection in order to understand the complicity between the police and criminals as fundamental to the market for stolen cars in the province. Using data from in-depth interviews and official documents, the article examines how exactly the police protect thieves, dismantlers and distributors of cars and/or auto parts. It analyses three elements that condition the sale of illegal protection to criminals by the police: threats and selective implementation of penalties; control of consequences; and bureaucratic falsification.

That illegal markets thrive is something of a puzzle to sociology. Despite the lack of legal frames—crucial for conflict resolution, regulation of competition, and formal sources of credit—new illegal markets continue to emerge. Thus an analysis of informal social mechanisms is essential for a better understanding of illegal markets’ internal coordination. The main goal of this chapter is to dissect the role of one of these mechanisms—state-sponsored protection rackets—in the context of illegal markets. This type of protection racket means a selective non-enforcement of the law, an action carried out intentionally by politicians and police forces in order to capture economic resources. I provide evidence that such an informal mechanism is present on a massive scale at La Salada, a huge illegal and informal marketplace close to Buenos Aires city center. The chapter seeks to make a contribution on informal mechanisms fostering unlawful exchanges.

In this work, we aim to study the role culture plays as an economic resource, especially for tourism promotion. Such conception is the result of changes in urban planning, international tourism tendencies and economy, politics and culture in general. Culture can generate income through tourism, crafts and other cultural activities.” Such urban transformations in Buenos Aires city have increased since the end of convertibility and become the essential resource for development. In order to carry out this study, we have worked with secondary statistical information elaborated by local administration institutions, such as the Ministry of Culture (Buenos Aires City Government) and CEDEM (Studies Center for Metropolitan Economic Development, Secretary of Economic Development, Buenos Aires City Government). This methodology helps us analyse the increase not only of artistic activities but of the consumption of cultural services through tourism, especially with the construction and promotion of tango as a trademark for Buenos Aires city.

Several accounts of the Baring crisis, 1890–7, are available.1 Among these is my own, chapter xiv of Britain and Argentina in the Nineteenth Century (Oxford, 1960), based upon the Foreign Office papers in the Public Record Office, contemporary periodical literature and secondary works such as the now little-noticed classic, J. H. Williams, Argentine International Trade under Inconvertible Paper Money, 1880–1900 (Cambridge, Mass., 1920). My first purpose in exploring beyond the sources used forty years ago, in the archives of the Bank of England, Baring Brothers & Co., N. M. Rothschild, W. H. Smith and the Marquis of Salisbury, is to correct at least one error in my original work, and this unfortunately repeated by others. My second is to discover whether or not further study of archival material confirms, modifies or denies any of my first conclusions about the role of the Argentine government in the solution of the Baring crisis.The principal error corrected concerns the form of Barings' involvement in Argentine affairs in the late 1880s. They did not get into difficulties because they underwrote a large loan to the Argentine government for the purpose of expanding the water supply and sewage system of Buenos Aires. The fact is that they promoted a private enterprise which took over the water and sewage system of Buenos Aires, and this failed for a number of reasons set out below.As to my original conclusions about the Baring crisis, they have been confirmed by the archival material considered. The solution of the Baring crisis was made possible by the policies devised and enforced by the Argentine government.

Rattus norvegicus, the brown or Norway rat, is the most abundant mammal after humans in urban areas, where they live in close proximity to people. Among rodent-borne diseases, the reservoir role of Norway rats of zoonotic parasites in cities has practically been ignored. Considering the parasitic diseases in the One Health approach, we intended to identify and quantify the zoonotic intestinal protozoans (ZIP) in an urban population of R. norvegicus in the city of Barcelona, Spain. We studied the presence of ZIP in 100 rats trapped in parks (n = 15) as well as in the city’s sewage system (n = 85) in the winter of 2016/17. The protozoans were molecularly identified by means of a multiplex PCR (AllplexTM Gastrointestinal Panel-Parasite Assay). We also investigated the presence of co-infections among the species found. Four ZIP were identified, presenting significant prevalences in sewers, specifically Blastocystis (83.5%), Giardia duodenalis (37.7%), Cryptosporidium spp. (34.1%), and Dientamoeba fragilis (14.1%). Several co-infections among the detected ZIP were also detected. The reservoir role of ZIP that Norway rats play in cities as well as the role rats may play as sentinels of zoonotic parasites affecting humans in urban areas are strongly backed up by our findings. The increasing worldwide urbanization, climate change, and the COVID-19 pandemic are factors that are producing an increase in human–rat interactions. Our results should be considered a warning to the authorities to intensify rat control and surveillance in public health interventions.
