Aislamiento e identificación de bacterias ácido lácticas con potencial probiótico en bovinos Holstein.
Provedor de dados: 32
Autores: Caballero Cervantes, Yesenia.
El principal problema de salud en becerras de reemplazo son las diarreas provocadas por Escherichia coli enterotóxica. El uso de microorganismos pertenecientes al grupo de bacterias ácido lácticas (BAL) en la etapa de lactancia es benéfico para combatir la incidencia de diarreas e incrementar la ganancia de peso. Sin embargo, se ha reportado inconsistencia en los efectos benéficos de los productos comerciales. Por lo anterior, el objetivo de este estudio fue aislar y seleccionar BAL con potencial probiótico de mucosa oral de becerros lactantes, calostro y leche de vacas Holstein que puedan ser consideradas para el suministro de becerras en México. Para ello, se realizó el aislamiento en caldo Man Rogosa Sharp (MRS) y en agar MRS para la obtención de...

Propuesta de una nueva metodología para diferenciar las cepas de Yersinia ruckeri de las de Hafnia alvei
Provedor de dados: 20
Autores: Aguilera, Y.; Martínez, M.T.; Silveira, R.
El objetivo del estudio fue revisar la identificación de dos posibles cepas de Yersinia ruckeri aisladas de diferentes epizootias, diagnosticadas como septicemia bacteriana en 2009 en tilapia cultivada en jaulas, para esclarecer su papel en el cuadro clínico, ya que en los animales afectados no se observaron los signos característicos de la yersiniosis. Se realizó una amplia batería de pruebas bioquímicas mediante técnicas convencionales. La incubación de la motilidad, del Citrato de Simons y del Voges Proskauer, se hizo por duplicado, una réplica se incubó a 25 ºC y la otra, a 37 ºC, lo que permitió identificar a las cepas como Hafnia alvei, que no es un patógeno reconocido de los organismos acuáticos. Se propone un esquema para diferenciar las cepas de...

Extended serotyping scheme for &lt;i&gt;Vibrio anguillarum&lt;/i&gt; with the definition and characterization of seven provisional O-serogroups
Provedor de dados: 27
Autores: Pedersen, K.; Grisez, L.; van Houdt, R.; Tiainen, T.; Ollevier, F.P.; Larsen, J.L.
The present paper summarizes the serotyping scheme of the fish pathogenic bacterium &lt;i&gt;Vibrio anguillarum&lt;/i&gt; 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&lt;sub&gt;2&lt;/sub&gt;3. However, the existence of further &lt;i&gt;V. anguillarum&lt;/i&gt; strains that were not typable with any of the 23 O-antisera suggested the existence of additional...

ABSTRACT The objective of this study was to evaluate the adjustment quality of nonlinear models to data organs growth, carcass and body components of meat-type (Coturnix coturnix coturnix) and japanese laying-type (Coturnix coturnix japonica) quail. A total of 1350 quails from one to 42 d old were distributed in a completely randomized design, with five replicates each. To determine the organs growth (gut, heart, liver and gizzard), carcass and body components (wing, thigh and drumstick, back and breast), two quails per repetition were slaughtered weekly. The data were evaluated in function of different nonlinear models (Logistical, Brody, Richards, Von Bertalanffy and Gompertz). All models studied adjusted the data, differing in adjustment quality.

Provedor de dados: 48
Autores: BERDEN-ZRIMEC,MAJA; FLANDER-PUTRLE,VESNA; DRINOVEC,LUKA; ZRIMEC,ALEXIS; MONTI,MARINA.
Prorocentrum minimum is a potentially harmful and widely distributed marine dinoflagellate. Several P. minimum strains have already been studied, showing phylogenetical relations of strains isolated from the same geographical regions. Similarity among the strains was further examined on the basis of their physiology. Pigment composition and concentration, as well as delayed fluorescence (DF) decay kinetics and intensity, were measured in four P. minimum strains isolated from the Baltic and Adriatic Seas. The strains were grown at two salinities characteristic of the Baltic (8 PSU) and North Adriatic Seas (32 PSU). Strain differences in DF decay kinetics and growth did not always follow their genetic relations. While two strains showed similarities to the...

Autores: Fajardo,Thor Vinícius Martins; Kin,Aléxis Cardama; Nickel,Osmar.
ABSTRACT: Grapevine rupestris stem pitting-associated virus (GRSPaV) is one of the most common viruses of grapevine. It is involved in the graft-transmissible disease rupestris stem pitting of the rugose wood complex. The objective of the research was to perform the molecular characterization of the coat protein (CP) gene of sixteen Brazilian GRSPaV isolates aiming to determine the occurrence of molecular variants (strains) of this virus. Nine grapevine samples were evaluated, from which dsRNA was extracted. Nucleotide sequences were generated by Next generation sequencing (NGS). Fifteen complete sequences of the GRSPaV CP gene were obtained and phylogenetically analyzed. Multiple alignments of the sequences showed identities of nucleotides ranging from...
