INFLUENZA A H1N1/2009 PANDéMICA EN CERDOS Y OTRAS ESPECIES ANIMALES
Abeledo,María Antonia; Alfonso,P;
Revista de Salud Animal , 2010,
Abstract: cases of pandemic h1n1/2009 influenza occurred in pigs and other animals up to january/ 2010 are described and analysed. countries reporting swine cases have been increasing over time, but mild with variable morbidity and mortality almost nule. the infection source has been mostly attributed to the occurrence of workers with flu symptoms. the diagnosis was done by molecular techniques and the main measures applied were of general type, such as quarantine and enhancing the biosecurity on the facilities. it is also emphasizes on avoiding direct contact with sick pigs. the virus has also been reported in other species such as turkeys, cats, dogs and ferrets, among others, although the role of these in the epidemiological chain of the disease is unknown. it is necessary to warn on the needs of increasing the surveillance mainly in pigs, due to the importance of this specie on epidemiology of the disease.

Abstract: Research on credibility and faking is essential in different areas of psychology and especially in the forensic field. The investigations performed by Arce and Farina are recognised as being among the most notable of all the existing investigations, with the development of the Global Evaluation System (GES) that has been found to be especially effective in assessing the credibility of testimony and malingering mental health cases. The application of this procedure to 20 people accused under the judicial system of Social Security fraud for malingering a permanent work incapacity by way of a mental disorder, showed that the procedure described in the GES was effective for the correct classification of the malingers. Furthermore, data supported the categorising of malingers, consisting of whole malingers (those mentally healthy that effectively simulate a permanent work incapacity), partial malingers (those with temporary or no mental work incapacity disease, who claim for a permanent work incapacity), over malingers (those with permanent work incapacity mental disorders who exaggerate the severity of their mental health) and incompetent malingers (those who claimed to have permanent work incapacity but in their mental health assessment, were observed to have no mental health disorder.). Protocols for the forensic evaluation of malingering fitted to each categorization derived from the results obtained. The theoretical and practical implications of forensic assessment are discussed.
ALGUNAS CONSIDERACIONES PARA EL SACRIFICIO SANITARIO MASIVO DE AVES DE CORRAL EN BROTES DE INFLUENZA AVIAR
Alfonso,P; Percedo,María Irian; Abeledo,María Antonia; Fernández,A;
Revista de Salud Animal , 2007,
Abstract: in severe disease outbreaks, large numbers of animals may need to be killed for control purposes, which is complex. this task results in sanitary, environmental and ethical problems no completely solved worldwide. in the case of poultry industry, it is very difficult because individuals are raised at high stocking densities. in addition, the zoonotic potential of avian influenza is increased, so their slaughter on premises suspected to be ai infected, must be completed with special concern. this paper summarizes the main considerations for taking decisions regarding slaughter of poultry infected by ai virus, the methods for killing them in such cases according to the safeguarding personnel involved, the impact on the environment, animal welfare aspects as well as the proper disposal of dead birds and contaminated waste.

Abstract: the objective of this work was to carry out a serologic study of several adult bovine herds selected by their potentiality for trade. a total of 597 sera samples of healthy adults, coming from pinar del río, habana, ciudad habana and villa clara was analyzed by an indirect elisa. the 25.9% of the samples studied was positive to antibodies against blv. the results obtained coincide with previous reports for the region, where there is a high prevalence of antibodies to this virus. the study allowed to obtain information about the presence of antibodies to blv in adults. the results suggest the necessity of carrying out a survey in order to determine seroprevalence in representative herds of the whole country, keeping in mind that the major economic impact of the disease is on the international trade.

REDVET , 2005,
Abstract: La leptospirosis es una enfermedad zoonótica de focalidad natural que teniendo en cuenta el tipo de explotación, manejo, medidas protectivas y vigilancia epidemiológica podemos controlarla. De ahí que el objetivo de nuestro trabajo halla sido el determinar las características clínico-epizootiologicas en focos activos de leptospirosis en cerdos e identificar los serovares presentes a través del aislamiento. Para lograrlo nos propusimos dos experimentos, uno relacionado con la caracterización epizoótica de dos focos de leptospirosis porcina, en los que se presentaron índices de aborto de 5 y 6 % respectivamente. El otro experimento abordó el aislamiento e identificación de cepas de leptospira encontrada en los focos, la caracterización general de las unidades, investigación serológica relacionada con la enfermedad y diagnostico diferencial fueron actividades contempladas en el experimento, así como las descripciones de aislamiento y circulación del serovar Tarassovi por primera vez en Cuba en animales autóctonos, esto ocurrió sin grandes alteraciones de los indicadores productivos y reproductivos.Leptospirosis is a zoonotic disease occurring in natural foci, and could be controlled, taking into consideration: type of exploitation, protective measures and epidemiologic surveillance. The objective of this work is to determine the clinical and epidemiological characteristics of swine leptospirosis in disease active foci, and identify the serological varieties by means of isolation. Two experiments were developed, one related with the epidemiological characterization of swine leptospirosis foci, in which abortion occurred on 5 and 6% respectively; the second experiment was about the isolation and identification of Leptospira strains from the foci, general characterization of the piggeries: serological research related with the disease and its differential diagnosis, were activities within this experiment. Descriptions of isolation and circulation of the Tarassovi serovar, for the first time in Cuba, occurred without alterations of the productive and reproduction indexes.
ALGUNAS PAUTAS PARA ESTABLECER UNA ESTRATEGIA DE VIGILANCIA EPIDEMIOLóGICA DE LA INFLUENZA AVIAR

Revista de Salud Animal , 2008,
Abstract: the explosive and almost simultaneous appearance of avian influenza (ai) in multiple countries worldwide has been interpreted as evidence of weakness of the surveillance and early warning systems for noticing ai introduction and spread hazards. countries or regions can adopt more or less intensive surveillance systems depending on the surveillance systems pre-established, poultry industry characteristics, risk factors assessed and resources available. however, it is unquestionable the need of enhancing either passive or active surveillance. the new ai profile has increased the availability of techniques and means for surveillance whose selection has certain complexities for establishing an effective diagnostic algorithm. the prevention management and control of eventual sanitary disasters demand from the veterinary services to have an epidemiological surveillance strategy in order to increase the capacities of alert and early responses at local level. in this paper, some guidelines for organizing an avian influenza epidemiological surveillance system are pointed out.
