ABSTRACT
Small ruminant farming is of socio-economic and environmental importance to many rural communities around the world. The SMARTER H2020 project aims to redefine genetic selection criteria to increase the sustainability of the sector. The objective of this study was to analyse the selection and breeding management practices of small ruminant producers and breeders, linked with socio-technical elements that shape them. The study is based on farm surveys using semi-structured interviews conducted in five countries (France, Spain, Italy, Greece, and Uruguay) across 272 producers and breeders of 13 sheep and goat breeds, and 15 breed × system combinations. The information was collected in four sections. The first and second sections dealt with general elements of structure and management of the system and the flock/herd. The third section focused on selection and breeding management practices: criteria for culling and replacement of females, selection criteria for males, use of estimated breeding values and global indexes, and preferences for indexing new traits to increase the sustainability of their system. The fourth section aimed to collect socio-technical information. We used a data abstraction method to standardise the representation of these data. A mixed data factor analysis followed by a hierarchical ascending classification allowed the characterisation of three profiles of selection and breeding management: (1) a profile of producers (n = 93) of small flocks/herds, with little knowledge or use of genetic selection and improvement tools (selection index, artificial insemination, performance recording); these farmers do not feel that new traits are needed to improve the sustainability of their system. (2) a profile of producers (n = 34) of multibreed flocks/herds that rely significantly on grazing; they are familiar with genetic tools, they currently use AI; they would like the indexes to include more health and robustness characteristics, to make their animals more resistant and to increase the sustainability of their system. And (3) a profile of producers or breeders (n = 145) of large flocks/herds, with specific culling criteria; these farmers are satisfied with the current indexes to maintain the sustainability of their system. These results are elements that can be used by private breeding companies and associations to support the evolution of selection objectives to increase the resilience of animals and to improve the sustainability of the small ruminant breeding systems.

La coinfección entre el Treponema pallidum y el virus de la inmunodeiciencia humana (VIH) altera el curso clínico clásico de la sífilis aumentando la probabilidad de aparición de formas atípicas del secundarismo sifilítico. Entre estas formas se ha descripto a la sífilis elegante, entidad caracterizada por un exantema maculopapuloso descamativo, de aspecto anular, por lo general, con indemnidad de las regiones palmo plantar y de las mucosas. Se presenta un caso de sífilis secundaria, con lesiones típicas por su aspecto y localización, de sifílides elegantes en una paciente con diagnóstico de sida
Co-infection between Treponema pallidum and HIV alters the classic clinical course of syphilis, increasing the likelihood of atypical forms of syphilitic secondaryism. Among these forms, elegant syphilis has been described, an entity characterized by a desquamating maculopapular rash of annular appearance, with indemnity of the palmoplantar surface and mucous regions. Here, we present a case of secondary syphilis with typical lesions of elegant syphillides, in a patient diagnosed with AIDS

La tuberculosis (TB) es una enfermedad infectocontagiosa de gran importancia en la salud pública y representa una de las 10 principales causas de muerte a nivel mundial. Una de las complicaciones del tratamiento antituberculoso es la respuesta paradojal, que se define como un empeoramiento clínico o la aparición de nuevas lesiones en un paciente que comienza un tratamiento antifímico. Esta reacción está mediada por una respuesta de hipersensibilidad a los antígenos de Mycobacterium tuberculosis. Suele aparecer entre 2 y 4 meses luego de iniciado el tratamiento antituberculoso, generalmente precedida por una mejoría inicial del cuadro. Se presenta una mujer con sida y tuberculosis ganglionar con respuesta paradojal a la terapéutica antimicobacteriana y se realiza una revisión bibliográfica del tema.
Tuberculosis (TB) is an infectious disease of great importance in public health and represent one of the 10 leading causes of death worldwide. One of the complication of the antituberculous treatment is the paradoxical reaction, which is defined as a worsening or the appearance of new lesions in a patient receiving antimicobacterial treatment. This paradoxical response is mediated by a hypersensitivity reaction to mycobacterial antigens. It usually appears between 2 and 4 months after initiation of tuberculosis treatment and is preceded by an initial improvement of the clinical condition. Here, we describe a woman with AIDS and lymph node tuberculosis with a paradoxical reaction to antimycobacterial therapy and the subject is reviewed.
