      Vector-borne pathogens are responsible for serious emerging diseases and Rangelia vitalii, the etiologic agent of canine rangeliosis, is one of the most pathogenic tick-borne pathogens for dogs in South America. This ...

    • Use of touch-down polymerase chain reaction to enhance the sensitivity of Mycobacterium bovis detection 

      Zumarraga, Martin Jose; Meikle, Virginia; Bernardelli, Amelia; Abdala, Alejandro Ariel; Tarabla, Hector Dante; Romano, Maria Isabel; Cataldi, Angel Adrian (Sage Publications, 2005-05)
      The confirmatory diagnosis of Mycobacterium bovis (M. bovis) in animal samples is carried out by culture in Stonebrink media. However, culture is very slow because of the extremely long duplication time of the bacillus and ...

    • Utilization of molecular and conventional methods for the identification of nontuberculous mycobacteria isolated from different water sources 

      Tortone, Claudia Andrea; Zumarraga, Martin Jose; Gioffre, Andrea; Oriani, Delia Susana (Wolters Kluwer - Medknow, 2018-03)
      Background: The environment is the nontuberculous mycobacteria (NTM) reservoir, opportunistic pathogens of great diversity and ubiquity, which is observed in the constant description of new species capable of causing ...

    • Validation of reference genes for quantitative PCR in Johnsongrass (Sorghum halepense L.) under glyphosate stress 

      Ulrich, Maria Noelia; Muñiz-Padilla, Esteban; Corach, Alejandra; Hopp, Horacio Esteban; Tosto, Daniela Sandra (MDPI, 2021-08)
      Weeds are one of the main causes of the decrease in crop yields, with Johnsongrass (Sorghum halepense L.) being one of the most significant. Weeds can be controlled by herbicides, but some have developed resistance. ...

    • Variation in the VP1 Gene of Foot-And-Mouth Disease Virus Serotype a Associated with Epidemiological Characteristics of Outbreaks in the 2001 Epizootic in Argentina 

      Pérez, Andrés M.; Konig, Guido Alberto; Spath, Ernesto Juan; Thurmond, Mark C. (Sage Publishing, 2008)
      A mixed binomial Bayesian regression model was used to quantify the relation between nucleotide differences in the VP1 gene of Foot-and-mouth disease virus (FMDV) serotype A, and epidemiologic characteristics of the outbreaks ...
