Resumen

En Argentine, la préoccupation pour le développement du système productif relègue au second plan la question environnementale. Le modèle extractiviste-exportateur fondé sur l’exploitation des ressources naturelles à grande échelle provoque des dégâts environnementaux majeurs et des conflits avec les populations autochtones. Les organisations syndicales dominantes soutiennent ce modèle de développement économique, d’autres plus marginales défendent la cause environnementale en s’alliant avec les mouvements sociaux autochtones.

Professor Voyvodic’s call for cultural competence as an ethical requirement challenges perceptions of the legal profession as inherently and necessarily morally neutral. While lawyers wrestle with the boundaries of ethical mandates, alternative dispute resolution practitioners have adopted their own codes of ethics following very much in the path of the law. Although expanding dispute resolution options for disputants, many theorists have warned of the potential of informalism to undermine natural justice principals.

Bovine anaplasmosis is a disease caused by Anaplasma marginale, a tick-borne bacterial pathogen with global distribution, primarily determined by the range of its vector. In Argentina, Rhipicephalus microplus is the main species associated with A. marginale transmission, even though this bacterium can also be mechanically transmitted. We studied complex infections (more than one A. marginale variant) in naturally infected bovines from two different epidemiological contexts: a region with the tick vector and a tick-free region.

Anaplasma marginale is a tick-borne pathogen that causes bovine anaplasmosis, which affects cattle around the world. Despite its broad prevalence and severe economic impacts, limited treatments exist for this disease. Our lab previously reported that a high proportion of Rickettsia bellii, a tick endosymbiont, in the microbiome of a population of Dermacentor andersoni ticks negatively impacts the ticks’ ability to acquire A. marginale. To better understand this correlation, we used mixed infection of A. marginale and R. bellii in D. andersoni cell culture. We assessed the impacts of different

ABSTRACT Anaplasma marginale is an intraerythrocytic rickettsial pathogen of cattle in which infection persists for the life of the animal. Persistent A. marginale infection is characterized by repetitive rickettsemic cycles which we hypothesize reflect emergence of A. marginale antigenic variants. In this study, we determined whether variants of major surface protein 2 (MSP-2), a target of protective immunity encoded by a polymorphic multigene family, arise during persistent rickettsemia.

ABSTRACT Anaplasma marginale is a tick-borne pathogen, one of several closely related ehrlichial organisms that cause disease in animals and humans. These Ehrlichia species have complex life cycles that require, in addition to replication and development within the tick vector, evasion of the immune system in order to persist in the mammalian reservoir host. This complexity requires efficient use of the small ehrlichial genome. A. marginaleand related ehrlichiae express immunoprotective, variable outer membrane proteins that have similar structures and are encoded by polymorphic multigene fami

ABSTRACT Anaplasma marginale, an intraerythrocytic ehrlichial pathogen of cattle, establishes persistent infections in both vertebrate (cattle) and invertebrate (tick) hosts. The ability ofA. marginale to persist in cattle has been shown to be due, in part, to major surface protein 2 (MSP2) variants which are hypothesized to emerge in response to the bovine immune response. MSP2 antigenic variation has not been studied in persistently infected ticks.

The interregional cohort survival model developed by Rogers is an excellent one that includes all of the three population processes: birth-death, aging, and interregional migration. Rogers's model, however, has been rarely implemented because it requires detailed data concerning cohortwise (that is by age and sex) interregional migration tables which are not usually available as published data. The most usual case is that only marginal tables that are from different sources can be obtained. However, in this case, those marginal tables necessarily show inconsistency in the sense that they do no

Resumen

A role of the Linnaean taxonomy in the arising of historical-biogeographical hypotheses is envisioned. The first example concerns the presumed hybrid origin of an Eastern-Sudetic endemic Aconium plicatum subsp. sudeticum. It was described on the basis of a unique character set including glandular hairiness of the indumentum. A PCR-RAPD+ISSR fingerpriting confirmed the supposition based on the morphological analysis. The second example is dealt with the marginal populations. They are of special interest because of the ecological and population genetic phenomena, including genetic drift and subs

Resumen

Understanding interactions between pathogens at the level of the individual host and the population in West Africa, may have noteworthy implications for predictions of diseases emergence and disease control programmes. Hence, the current study was aimed at investigating the interactions between Anaplasma marginale, Babesia bigemina and B. bovis in West African cattle. Twelve sentinel steers in each of the eight selected herds were randomly chosen to perform a one-year-long survey designed to monthly collect blood sample and to diagnose possible infections of the steers.

Resumen

ABSTRACT Anaplasma phagocytophilum is the causative agent of an emerging tick-borne zoonosis in the United States and Europe. The organism causes a febrile illness accompanied by other nonspecific symptoms and can be fatal, especially if treatment is delayed. Persistence of A. phagocytophilum within mammalian reservoir hosts is important for ensuring continued disease transmission. In the related organism Anaplasma marginale, persistence is associated with antigenic variation of the immunoprotective outer membrane protein MSP2. Extensive diversity of MSP2 is achieved by combinatorial gene conv

Resumen

ABSTRACT Strain superinfection affects the dynamics of epidemiological spread of pathogens through a host population. Superinfection has recently been shown to occur for two genetically distinct strains of the tick-borne pathogen Anaplasma marginale that encode distinctly different surface protein variants. Superinfected animals could serve as a reservoir for onward transmission of both strains if the tick vector is capable of acquiring and transmitting both strains. Whether competition among strains during development within the tick vector, which requires sequential invasion and replication

Resumen

ABSTRACT The relative fitness of arthropod-borne pathogens within the vector can be a major determinant of pathogen prevalence within the mammalian host population. Strains of the tick-borne rickettsia Anaplasma marginale differ markedly in transmission efficiency, with a consequent impact on pathogen strain structure. We have identified two A. marginale strains with significant differences in the transmission phenotype that is effected following infection of the salivary gland. We have proposed competing hypotheses to explain the phenotypes: (i) both strains are secreted equally, but there is

This article discusses improvements made to the methodology of the Housing and Urban Development (HUD) point-in-time (PIT) homeless census. HUD’s PIT results are presented to Congress as official data for policy consideration. Yet, PIT methodology focuses on visible street homeless individuals and those in shelters while neglecting the “marginally housed” or less visible homeless who live in automobiles or temporarily stay with friends and extended family. Being a hidden population, the marginally housed has been a traditionally difficult population to study. We replicated HUD’s PIT count but

La diffusion des méthodes contraceptives, notamment la progression de la pilule, s'est ensuite faite rapidement. La dernière enquête réalisée en 1994 (Ined/Insee) permet de faire le point sur les pratiques contraceptives. La contraception est généralisée à tous les âges : moins de 5 % de femmes prennent le risque d'une grossesse non désirée. On observe une forte progression, dans les générations s
