Debido a la importancia que han adquirido los especímenes neomachos en la producción de poblaciones todo-hembras triploides, se ha hecho cada vez mas necesario investigar la manera de poder reconocer su condición sexual sin la necesidad de sacrificar al pez. Este conocimiento permitiría entregar al acuicultor una herramienta necesaria para el manejo de éstos stoks. En este estudio se analiza la factibilidad de reconocer a un neomacho de trucha arcoiris (Oncorhynchus mykiss), por medio de un análisis serológico, basándose en que un neomacho por ser un individuo hembra revertido hormonalmente de sexo, presentaría niveles detectables de la proteína femenina vitelogenina. Se compararon las concentraciones de proteínas séricas presentes en machos, hembras,... |

The present paper summarizes the serotyping scheme of the fish pathogenic bacterium <i>Vibrio anguillarum</i> and defines seven additional O-serogroups. Strains, collected in our laboratories that were nontypable with antisera against the previously defined 16 O-serotypes, were used for generating new antisera and were characterized further by means of LPS profiles, Western blots, and serological reactions. On the basis of the results, it is suggested that the seven new O-serogroups are to be included in the existing serotyping system as serotypes O17-O<sub>2</sub>3. However, the existence of further <i>V. anguillarum</i> strains that were not typable with any of the 23 O-antisera suggested the existence of additional... |
