  2. Seroprevalence and risk factors associated with bovine herpesvirus type 1 (BHV1) infection in non-vaccinated cattle herds in Andalusia (South of Spain)

    González-García, M.A.; Arenas-Casas, Antonio; Carbonero-Martínez, Alfonso; Borge-Rodríguez, Carmen; García-Bocanegra, Ignacio; Maldonado, J.L.; Gómez-Pacheco, Juan M.; Perea-Remujo, J.A.
    An epidemiological and serological survey of bovine herpesvirus 1 (BHV1) infection was conducted in Andalusia from January to April of 2000. A total of 4,035 blood samples were collected from 164 herds. A questionnaire, which included variables potentially associated with infection, was filled out for each herd. Serum samples were obtained to identify specific BHV1 antibodies and were tested using a blocking ELISA test. The observed crude odds ratio (OR) (estimate of the chance of a particular event occurring in an exposed group in relation to its rate of occurrence in a nonexposed group) for vaccination is 9.8 (95 % confidence interval: 8.3-11.7). The vaccinated...

  3. Overcoming function annotation errors in the Gram-positive pathogen Streptococcus suis by a proteomics-driven approach

    Rodríguez-Ortega, Manuel J.; Luque-Moreno, Inmaculada; Tarradas-Iglesias, Carmen; Bárcena, J.A.
    Background: Annotation of protein-coding genes is a key step in sequencing projects. Protein functions are mainly assigned on the basis of the amino acid sequence alone by searching of homologous proteins. However, fully automated annotation processes often lead to wrong prediction of protein functions, and therefore time-intensive manual curation is often essential. Here we describe a fast and reliable way to correct function annotation in sequencing projects, focusing on surface proteomes. We use a proteomics approach, previously proven to be very powerful for identifying new vaccine candidates against Gram-positive pathogens. It consists of shaving the surface of intact cells with two proteases, the specific cleavage-site trypsin and...

    Cabezón, Oscar; García-Bocanegra, Ignacio; Molina-López, Rafael; Marco, Ignasi; Blanco, Juan M.; Höfle, Ursula; Margalida, Antoni; Bach-Raich, Esther; Darwich, Laila; Echeverría, Israel; Obón, Elena; Hernández, Mauro; Lavín, Santiago; Dubey, Jitender P.; Almería, Sonia
    Toxoplasma gondii is a zoonotic intracellular protozoan parasite of worldwide distribution that infects many species of warm-blooded animals, including birds. To date, there is scant information about the seropositivity of T. gondii and the risk factors associated with T. gondii infection in wild bird populations. In the present study, T. gondii infection was evaluated on sera obtained from 1079 wild birds belonging to 56 species (including Falconiformes (n = 610), Strigiformes (n = 260), Ciconiiformes (n = 156), Gruiformes (n = 21), and other orders (n = 32), from different areas of Spain. Antibodies to T. gondii (modified agglutination test, MAT titer $1:25) were found...

  5. Quantitative analysis of the immune response upon Salmonella typhimurium infection along the porcine intestinal gut

    Collado-Romero, Melania; Arce Jiménez, Cristina; Ramírez-Boo, M.; Carvajal, Ana; Garrido, Juan J.
    Salmonella enterica serovar Typhimurium causes enteric disease and compromises food safety. In pigs, the molecular response of the intestine to S. typhimurium has been traditionally characterized by in vitro models that do not reflect the actual immunological competence of the intestinal mucosa. In this work, we performed an oral S. typhimurium infection study to obtain insight into the in vitro response in three different sections (jejunum, ileum and colon) of the porcine intestine. For this, samples from onemonth- old infected piglets were collected during a time course comprising 1, 2, and 6 days post inoculation to evaluate the intestinal response by quantifying the mRNA expression of...

  6. Model to Track Wild Birds for Avian Influenza by Means of Population Dynamics and Surveillance Information

    Alba, Anna; Bicout, Dominique J.; Vidal, Francesc; Curcó, Antoni; Allepuz, Alberto; Napp, Sebastián; García-Bocanegra, Ignacio; Costa, Taiana; Casal, Jordi
    Design, sampling and data interpretation constitute an important challenge for wildlife surveillance of avian influenza viruses (AIV). The aim of this study was to construct a model to improve and enhance identification in both different periods and locations of avian species likely at high risk of contact with AIV in a specific wetland. This study presents an individualbased stochastic model for the Ebre Delta as an example of this appliance. Based on the Monte-Carlo method, the model simulates the dynamics of the spread of AIV among wild birds in a natural park following introduction of an infected bird. Data on wild bird species population, apparent...

    LaCourse, E. James; Perally, Samirah; Morphew, Russell M.; Moxon, Joseph V.; Prescott, Mark; Dowling, David J.; O'Neill, Sandra M.; Kipar, Anja; Hetzel, Udo; Hoey, Elizabeth; Brophy, Peter M.; Pérez, José; Zafra Leva, Rafael; Buffoni Perazzo, Leandro
    Background: Liver fluke infection of livestock causes economic losses of over US$ 3 billion worldwide per annum. The disease is increasing in livestock worldwide and is a re-emerging human disease. There are currently no commercial vaccines, and only one drug with significant efficacy against adult worms and juveniles. A liver fluke vaccine is deemed essential as short-lived chemotherapy, which is prone to resistance, is an unsustainable option in both developed and developing countries. Protein superfamilies have provided a number of leading liver fluke vaccine candidates. A new form of glutathione transferase (GST) family, Sigma class GST, closely related to a leading Schistosome vaccine candidate (Sm28), has...

    Gómez, J.C.; Huerta Lorenzo, Belén; Luque-Moreno, Inmaculada; Maldonado García, Alfonso; Astorga Márquez, Rafael J.; Tarradas-Iglesias, Carmen
    Biosecurity can be defined as all the applied measurements that take as a target to minimize the sanitary risks in a stock farm, and include measurements related to the facilities and the management. The efficacy of these measurements must be reflected in a decrease of the microorganism in different productive phases. A study was carried out to evaluate if the set of applied measurements influences the microbial uterine contamination after farrowing of healthy sows. Two swine farms were been completed about biosecurity measurements was completed and a microbiological study of uterine swabs of sows after the farrowing was carried out. A total of 60...

    García-Bocanegra, Ignacio; Pérez de Val, Bernat; Arenas-Montes, Antonio José; Paniagua, Jorge; Boadella, Mariana; Gortázar, Christian; Arenas-Casas, Antonio
    The control of bovine tuberculosis (bTB) is at a critical point in the last stage of eradication in livestock. Wildlife species recently have emerged infected with TB in Europe, particularly ungulates in the Iberian Peninsula. Epidemiological information regarding TB in wild ungulates including affected species, prevalence, associated risk factors and appropriate diagnostic methods need to be obtained in these countries. A cross-sectional study was carried out on wild artiodactyl species, including Eurasian wild boar (Sus scrofa) red deer (Cervus elaphus), roe deer (Capraelus capraelus), fallow deer (Dama dama), Spanish ibex (Capra pyrenaica hispanica) and mouflon (Ovis musimon), in Spain to assess the seroprevalence against Mycobacterium bovis...

    León Vizcaíno, L.; Carranza Guzmán, J.; Miranda García, Antonio; Hermoso de Mendoza, M.; Perea-Remujo, J.A.
    A serological inquiry on listeriosis of the domestic ruminants of the province of Cordoba (Spain) was made to know the epizootiology of the disease. The agglutination in tube with 2-mercaptoetanol technique was carried out using somatic antigens of the 1/2 and 4 serological types of Listeria monocytogenes. 2.685 samples of apparently healthy adult ruminants from 286 flocks have been investigated. In sheep we found 10 foci of the infection (11.9 per cent of the investigated flocks). In cattle we detected 15 foci (9.56 per cent). In goats we found 5 foci (10 per cent). In relation to the individuals, in...
