SYBR Green qPCR Technique for the Detection of in Açaí Pulp.

Chagas disease, which is found widely in Latin America and has a great impact on public health, is caused by the parasite . It is a neglected parasitic disease that urgently requires rapid diagnostic methods. The objective of this study was to develop a SYBR Green real-time quantitative polymerase chain reaction (qPCR) technique for the direct identification and quantification of from experimentally contaminated açai fruit samples.

Probiotics Bacillus toyonensis and Saccharomyces boulardii improve the vaccine immune response to Bovine herpesvirus type 5 in sheep.

There have been significant efforts toward the development of more efficient vaccines for animal health. A strategy that may be used to improve vaccine efficacy is the use of probiotics. Bovine herpesvirus 5 (BoHV-5) is an example of an important animal pathogen for which vaccines have provided only limited protection.

The role of quorum sensing in Escherichia coli (ETEC) virulence factors.

Quorum sensing (QS) is a signaling system among bacteria mediated by auto-inducer substances (AI). Whenever the concentration of these molecules reaches a threshold corresponding to a high cell density or quorum, the whole population starts a coordinated expression of specific genes. Studies have shown that epinephrine is also responsible for activating specific bacterial genes.

The immune modulation of Bacillus cereus var. Toyoi in mice immunized with experimental inactivated Bovine Herpesvirus Type 5 vaccine.

In recent years, there been significant progress toward develop more efficient vaccines. Different compounds with adjuvant capacity have been tested; however, no compound has emerged that suitable for universal use. Several efforts have been made to produce effective vaccines against Bovine herpesvirus 5 (BoHV-5), an important cattle pathogen.
