Immune response represents the initial arm of host defense against Koch’s bacillus. This review describes and discusses current knowledge of the host’s immune response to Mycobacterium tuberculosis infection. To improve the diagnosis of tuberculosis, more rapid diagnostic techniques have been investigated in recent years, such as mediators, receptors and activators of immunity, gamma-interferon, tumor...

Exopolysaccharides (EPS) may represent a viable inoculant carrier to replace peat and reduce production costs. In addition, the use of plant growth-promoting bacteria (PGPB), as Paenibacillus, in association with rhizobia represents a new technology that can improve the biological nitrogen fixation (BNF) and crop productivity. Thus, the present research aimed to characterize the EPS that are produced by R. tropici and... Read more.

The causative agent of bovine tuberculosis (BTB) is Mycobacterium bovis, a bacterium belonging to the M. tuberculosis complex (MTC). The definitive diagnosis is achieved through isolation and identification of M. bovis from clinical samples, using a combination of traditional culture and biochemical methods, which is considered the “gold standard”. This procedure is cumbersome and time-consuming. We... Read more.

Voacanga africana (Stapf) and Rauwolfia vomitoria (Afzel) (Apocynaceae) are traditional plants widely used in folkloric medicine. Methanol extracts of V. africana bark (VAB) and leaves (VAL), and R. vomitoria bark (RVB) and leaves (RVL) were evaluated for antioxidant and anthelmintic potentials. The antioxidant properties of the extracts were determined by the DPPH free radical scavenging method using ascorbic acid as... Read more.

Identifying the most suitable lithium compounds for fungal growth is important for the lithium (Li) enrichment of mushrooms. However, enrichment thus far has been carried out using LiCl. In an effort to identify an alternative source of lithium, we investigated the effect of five lithium compounds on lag phase, growth rate and biomass of ten species of white-rot fungi. The objective of this work was to make a screening... Read more.

As human populations grow and transform landscapes, contact with wildlife concomitantly increases. Disease emergence has been an important consequence of these contacts, with many of emerging infectious diseases in humans arising from wildlife reservoirs. Drug resistance is a very important dimension of disease emergence and tracing the source is a veritable containment strategy. Escherichia coli and Proteus spp. have... Read more.
