Extremely oligotrophic and complex-carbon-degrading microaerobic bacteria from Arabian Sea oxygen minimum zone sediments.

Sediments underlying marine hypoxic zones are huge sinks of unreacted complex organic matter, where despite acute O limitation, obligately aerobic bacteria thrive, and steady depletion of organic carbon takes place within a few meters below the seafloor. However, little knowledge exists about the sustenance and complex carbon degradation potentials of aerobic chemoorganotrophs in these sulfidic ecosystems. We isolated and characterized a number of aerobic bacterial chemoorganoheterotrophs from across a ~ 3 m sediment horizon underlying the perennial hypoxic zone of the eastern Arabian Sea.

Localized outbreaks of belonging to international high-risk clones in a south Indian hospital.

. is now considered as a major bacterial pathogen associated with hospital infections. Frequently, multidrug-resistant (MDR) and extensively drug-resistant (XDR) are being encountered.

Prediction of nitrofurantoin resistance among Enterobacteriaceae and mutational landscape of in vitro selected resistant Escherichia coli.

Nitrofurantoin (NIT) has long been a drug of choice in the treatment of lower urinary tract infections. Recent emergence of NIT resistant Enterobacteriaceae is a global concern. An ordinal logistic regression model based on PCR amplification patterns of five genes associated with NIT resistance (nfsA, nfsB, ribE, oqxA, and oqxB) among 100 clinical Enterobacteriaceae suggested that a combination of oqxB, nfsB, ribE, and oqxA is ideal for NIT resistance prediction.

Complete genome sequence of an extensively drug resistant (XDR) M. morganii SMM01 isolated from a patient with urinary and fecal incontinence.

Objective: M. morganii is a gram-negative, non-lactose fermenting and an opportunistic pathogen frequently associated with nosocomial infections. Although first isolated in 1906 from a pediatric fecal sample, not many M.

Genomic analysis of a multidrug-resistant Brucella anthropi strain isolated from a 4-day-old neonatal sepsis patient.

Objectives: Brucella anthropi is a Gram-negative, aerobic, motile, oxidase-positive, non-fermentative Alphaproteobacteria belonging to the family Brucellaceae. It is most commonly found in soil but is an emerging, opportunistic, nosocomial human pathogen. The objective of this study was to understand the genome features of a drug-resistant B.
