Escherichia albertii is a Gram-negative facultative anaerobic bacterium that causes diarrhoea in humans. This study shows the isolation of E. from hospitalized paediatric diarrhoeal cases and genome-based characteristics with putative virulence factors antimicrobial resistance. isolates were identified by species-specific PCR, targeting gene encoding cytolethal distending toxin ( Ea-cdt ). The genome was sequenced to identify (i) genes (ii) antibiotic resistance-encoding genes, including...
The effect of sodium selenite on anaerobic digestion waste sewage sludge (WSS) was studied. Interestingly, methane production enhanced at 2 mg/L and inhibited 100 during the WSS. Hydrolytic activity increased in correlation with concentrations (0 to mg/L). At acidogenesis stage, acetic acid accumulated more than 25 whereas it consumed for 10 days concentration selenite. Also, propionic decreased that butyric Although methanogenic activities were totally selenite, a high hydrogenotrophic...
Methane metabolism in wetlands involves diverse groups of bacteria and archaea, which are responsible for the biological decomposition organic matter under certain anoxic conditions. Recent advances environmental omics revealed phylogenetic diversity novel microbial lineages, have not been previously placed traditional tree life. The present study aimed to verify key players methane production, either well-known archaeal members or recently identified peat soils collected from wetland areas...
Bdellovibrio bacteriovorus is one of the predatory bacteria; therefore, it can act as a novel “living antibiotic,” unlike current antibiotics. Here predation Escherichia coli by B. was inhibited in presence Pseudomonas aeruginosa . This study investigated whether P. -induced inhibition associated with bacterial quorum sensing (QS). Each las , rhl or pqs QS mutant used to check activity E. cells using As result, increased system, whereas wild-type PA14 activity. Moreover, addition...
In this study, the effect of sodium tungstate on aerobic digestion waste sewage sludge (WSS) was investigated. Interestingly, enhanced methane production found according to increased concentration WSS. Acidogenesis stage influenced by because amount acetate decreased whereas that isobutyrate during anaerobic WSS supplemented with tungstate. Since consumed time WSS, pH in presence The analyses methanogenesis via acetoclastic and hydrogentrophic methanogens indicate from high addition,...
Available options to combat bacterial infections are getting scarce. We require innovative and imaginative approaches enhance the identification discovery of effective antimicrobials capable combating bacteria resistant multiple or all available drugs. These methods should either directly eliminate influence their viability indirectly by inhibiting virulence reducing resistance antibacterial agents. One interesting approach is analyze ancient remedies presumably used treat infections, try...
ABSTRACT The complete genome sequence of Bdellovibrio bacteriovorus 109J, a well-studied laboratory strain predatory bacteria, first determined in 2014. Here we report an improved B. incorporating 16 assembly and 87 nucleotide corrections. This revised will be helpful to studies on the bacteria.
Studies on the conditions and pollution routes of antibiotic-resistant bacteria (ARB) in rivers can help provide countermeasures against spread ARB. This study focused pristine uppermost stream a river, where Escherichia coli ( E. ) enterococci were detected, although flows through forest catchment. Antibiotic resistance isolated from river water, riverbed sediment, feces waterside animals, such as birds Mustelidae, investigated throughout year sites. was present 1.4% (7/494) strains 3.0%...
We report the complete genome of Paenibacillus sp. strain VCA1, which was isolated from sediment El Chichón Volcano. This consists 6,690,819 bp and 6,312 coding sequences, with 51.8% G+C content. Whole-genome sequencing performed to explore strain's biocontrol plant growth promotion properties.
Abstract Pseudomonas aeruginosa is the main bacterial model to study cooperative behaviors, since it yields exoproducts such as exoproteases and siderophores that act public goods can be exploited by selfish non-producers behave social cheaters. Non-producers of siderophore pyoverdine are typically isolated in media with low free iron, mainly casamino acids medium supplemented transferrin. Nevertheless, using a protein iron chelator could additionally select mutants unable produce degrade...
A challenge in the study of gastrointestinal microbiota (GITm) is validation genomic data with metabolic studies microbial communities to understand how networks work during health and sickness. To gain insights into metabolism GITm, feces from healthy sick rats cancer were inoculated a defined synthetic medium directed for anaerobic prokaryote growth (INC-07 medium). Significant differences between cultures individuals found: 1) consumption carbon source enzyme activity involved their...
Abstract Waterborne diseases due to pathogen contamination in water are a serious problem all over the world. Accurate and simultaneous detection of pathogens is important protect public health. In this study, we developed method simultaneously detect various pathogenic Escherichia coli by sequencing amplicons multiplex PCR. Our newly designed PCR amplified five genes for E. ( uidA , stx1 stx2 STh gene, LT gene). Additional two assays (for aggR eae ) were also included amplicon analysis. The...
The role of bacterial interaction is important for controlling functions; however, it has been not fully understood in microbial consortia (such as anaerobic digestion). In this study, fluorouracil (FU), which only an anticancer agent but also a quorum sensing (QS) inhibitor to some the Gram-negative bacteria, was found inhibit methane production from sewage sludge under condition shown result that presence FU 8 times lower than control (sewage without FU). Whereas did influence process...
