Modified microplate method for rapid and efficient estimation of siderophore produced by bacteria

3 Biotech, Journal Year: 2017, Volume and Issue: 7(6)

Published: Oct. 26, 2017

In this study, siderophore production by various bacteria amongst the plant-growth-promoting rhizobacteria was quantified a rapid and efficient method. total, 23 siderophore-producing bacterial isolates/strains were taken to estimate their ability standard method (chrome azurol sulphonate assay) as well 96 microplate Production of estimated in percent unit both methods. It observed that data obtained methods correlated positively with each other proving correctness By modified method, several strains can be qualitatively quantitatively at one go, saving time, chemicals, making it very less tedious, also being cheaper comparison currently use. The microtiter plate proposed here makes far easier screen character plant-associated bacteria.

Siderophore cheating and cheating resistance shape competition for iron in soil and freshwater Pseudomonas communities

Nature Communications, Journal Year: 2017, Volume and Issue: 8(1)

Published: Aug. 29, 2017

Abstract All social organisms experience dilemmas between cooperators performing group-beneficial actions and cheats selfishly exploiting these actions. Although bacteria have become model to study in laboratory systems, we know little about their relevance natural communities. Here, show that interactions mediated by a single shareable compound necessary for growth (the iron-scavenging pyoverdine) important consequences competitive dynamics soil pond communities of Pseudomonas bacteria. We find pyoverdine non- low-producers co-occur many While non-producers genes coding multiple receptors are able exploit compatible heterologous pyoverdines from other community members, producers differ the types they secrete, offering protection against exploitation with incompatible receptors. Our findings indicate there is both selection cheating resistance, which could drive antagonistic co-evolution diversification bacterial

Cross-protection and cross-feeding between Klebsiella pneumoniae and Acinetobacter baumannii promotes their co-existence

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Feb. 9, 2023

Acinetobacter baumannii and Klebsiella pneumoniae are opportunistic pathogens frequently co-isolated from polymicrobial infections. The infections where these co-exist can be more severe recalcitrant to therapy than caused by either species alone, however there is a lack of knowledge on their potential synergistic interactions. In this study we characterise the genomes A. K. strains single human lung infection. We examine various aspects interactions through transcriptomic, phenomic phenotypic assays that form basis for understanding effects antimicrobial resistance virulence during co-infection. Using co-culturing analyses secreted metabolites, discover ability cross-feed by-products sugar fermentation. Minimum inhibitory concentration testing mono- co-cultures reveals cross-protect against cephalosporin, cefotaxime.

Pathogens, microbiome and the host: emergence of the ecological Koch's postulates

FEMS Microbiology Reviews, Journal Year: 2018, Volume and Issue: 42(3), P. 273 - 292

Published: Jan. 8, 2018

Even though tremendous progress has been made in the last decades to elucidate mechanisms of intestinal homeostasis, dysbiosis and disease, we are only at beginning understanding complexity gut ecosystem underlying interaction networks. We also starting unravel that pathogens have evolved overcome barriers imposed by microbiota host exploit system their own benefit. Recent work these domains clearly indicates 'traditional Koch's postulates', which state a given pathogen leads distinct not valid for all 'infectious' diseases, but more complete complex interpretation postulates is needed order understand explain them. This review summarises current what defines healthy highlights recent uncovering interplay between host, its invading pathogens. Based on findings, propose new term 'ecological postulates'.

Probiotics and competitive exclusion of pathogens in shrimp aquaculture

Reviews in Aquaculture, Journal Year: 2020, Volume and Issue: 13(1), P. 324 - 352

Published: July 24, 2020

Abstract Probiotics, live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, offer an alternative to antibiotics and have become popular among shrimp farmers for use regulation of pond water quality, promotion growth prevention disease. Most probiotics are selected testing based their ability competitively exclude pathogens through bacterial antagonism assays, although mechanisms pathogen exclusion rarely investigated. In this review, we provide comprehensive overview competitive (interference exploitation competition) by species screened subsequently identified as inhibit pathogenic bacteria vitro . We show that current methods used identify potential preferentially select interference‐based may overlook many be considered probiotic. Furthermore, efficiency probiotic vivo improved considering suitability strategies farming conditions. highlight important limitations future directions screening identification aquaculture, aid development effective sustainable microbial management strategies.

Bacillus Responses to Plant-Associated Fungal and Bacterial Communities

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: June 23, 2020

Some members of root-associated Bacillus species have been developed as biocontrol agents due to their contribution plant protection by directly interfering with the growth pathogens or stimulating systemic resistance in host. As rhizosphere-dwelling bacteria, these bacilli are surrounded and constantly interacting other microbes via different types communications. With this review, we provide an updated vision molecular phenotypic responses upon sensing rhizosphere microorganisms and/or metabolites. We illustrate how spp. may react modulating production secondary metabolites, such cyclic lipopeptides polyketides. On hand, some developmental processes, biofilm formation, motility, sporulation also be modified interaction, reflecting adaptation multicellular communities microbial competitors for preserving ecological persistence. This review points out limited data available a global lack knowledge indicating that more research is needed order to, not only better understand ecology natural soil niche, but assess improve promising potential.
