| dc.description | Bovine mastitis today continues to be one of the diseases that causes the greatest economic impact in dairy farms, being one of the most significant diseases from the point of view of milk production and public health. Due to the continuous contact with the animals and the mismanagement that occurs at the time of carrying out the milking methods either manually or mechanically, it has allowed the persistence of a series of pathogens. For the development of the bibliographic document, an exhaustive investigation was carried out, collecting bibliographic information from books, magazines, articles from web pages, technical manuals, projects. The objective of the research is the characterization of the causal agents of bovine mastitis. Pathology caused by more than 100 different species of pathogenic microorganisms and 95% of these infections are originated (in order of importance) by bacteria, they are: S. aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, and S. epidermidis, the distribution of the agents that cause mastitis may be different, since in clinical cases the etiology may be due to bacteria that are present only for a short period of time, such as Escherichia coli, while subclinical mastitis can be caused by pathogens such as S. aureus, which can be present for long periods of time, producing only very slight signs on the cow's udder. In conclusion, whatever the causative agent of this pathology is (Gram Positive or Gram Negative) negatively influences the reproductive performance of cows, even the lesions that these bacteria can cause affect the mammary gland, for this, the bacteria must first penetrate, later adhere and finally invade the tissues. | es_ES |

| dc.description.abstract | La mastitis bovina en la actualidad continúa siendo una de las enfermedades que causa mayor impacto económico en las ganaderías orientadas a la producción de leche, siendo una de las enfermedades más significativas desde el punto de vista en la producción lechera y de salud pública. Por el continuo contacto con los animales y el mal manejo que se da al momento de llevar a cabo los métodos de ordeño bien sea en forma manual o mecánica, ha permitido la persistencia de una serie de agentes patógenos. Para el desarrollo del documento bibliográfico se realizó una investigación exhaustiva recolectando información bibliografía de libros, revista, artículos de páginas web, manuales técnicos y proyectos. El objetivo de la investigación es la caracterización de los agentes casuales de la mastitis bovina. Patología causada por más de 100 especies diferentes de microorganismos patógenos y el 95% de estas infecciones son originadas (en orden de importancia) por bacterias, que se encuentran: S. aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis y S. epidermidis, la distribución de los agentes que causan mastitis pueden ser diferentes, ya que en los casos clínicos la etiología puede ser por bacterias que están presentes sólo por un corto periodo de tiempo, como la Escherichia Coli, mientras que las mastitis subclínicas pueden ser causadas por patógenos como S. Aureus, que pueden estar presentes por largos periodos de tiempo, produciendo solamente signos muy leves en la ubre de la vaca. En conclusión, Cualquiera que sea el agente causal de esta patología ya sea Gram Positivo o Gram Negativo influye negativamente en el desempeño reproductivo de las vacas, incluso las lesiones que pueden llegar a causar estas bacterias afectan a la glándula mamaria, para ello primero la bacteria deberá penetrar, posteriormente adherirse y finalmente invadir los tejidos. | es_ES |
