Dark chocolate: delivery medium for probiotic NCIM 5671.

Unlabelled: Bifidobacteria are widely acclaimed probiotic bacteria, however, the fragile nature of the bacteria has rendered its delivery through food products a challenge. The aim of the present study was to develop probiotic dark chocolate by incorporating NCIM5671. The probiotic chocolate was prepared by adding to dark chocolate at the final tempering stage.

Proteome profiling identifies a link between the mitochondrial pathways and host-microbial sensor ELMO1 following infection.

Unlabelled: The host EnguLfment and cell MOtility protein 1 (ELMO1) is a cytosolic microbial sensor that facilitates bacterial sensing, internalization, clearance, and inflammatory responses. We have shown previously that ELMO1 binds bacterial effector proteins, including pathogenic effectors from and controls host innate immune signaling. To understand the ELMO1-regulated host pathways, we have performed liquid chromatography Multinotch MS3-Tandem Mass Tag (TMT) multiplexed proteomics to determine the global quantification of proteins regulated by ELMO1 in macrophages during infection.

The crosstalk between microbial sensors ELMO1 and NOD2 shape intestinal immune responses.

Microbial sensors play an essential role in maintaining cellular homoeostasis. Our knowledge is limited on how microbial sensing helps in differential immune response and its link to inflammatory diseases. Recently we have confirmed that ELMO1 (Engulfment and Cell Motility Protein-1) present in cytosol is involved in pathogen sensing, engulfment, and intestinal inflammation.

The WxxxE proteins in microbial pathogenesis.

Effector proteins secreted by pathogens modulate various host cellular processes and help in bacterial pathogenesis. Some of these proteins, injected by enteric pathogens Type Three Secretion System (T3SS) were grouped together based on a conserved signature motif (WxxxE) present in them. The presence of WxxxE motif is not limited to effectors released by enteric pathogens or the T3SS but has been detected in non-enteric pathogens, plant pathogens and in association with Type II and Type IV secretion systems.

In Vitro Comparative Analysis of Probiotic and Functional Attributes of Indigenous Isolates of Bifidobacteria.

In the present study, probiotic, safety and functional characteristics of eight indigenous bifidobacterial isolates were compared to identify suitable strains for functional food application. Among the isolates, six strains of Bifidobacterium longum and one each of Bifidobacterium breve and Bifidobacterium bifidum were identified by 16S rRNA, xfp and hsp60 gene sequencing. Diversity among these strains was established by RAPD and Rep-PCR.

Effect of Encapsulation on Viability of CFR815j and Physiochemical Properties of Ice Cream.

The health beneficial attributes of bifidobacteria and its safe association with the host gut has increased its significance as a probiotic. However delivering probiotic bifidobacteria with Minimum Biological Value (MBV) through product has always been a challenge. In the present study, an attempt was made to maintain the viability of native isolate of CFR 815j and deliver through ice-cream.
