Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.

Distribution and Efficiency of Hydrocarbon-Oxidizing Bacteria in a Freshwater Reservoir [PDF]

, 1984
Hydrocarbon-oxidizing bacteria were identified from three stations on DeGray Reservoir, Arkansas. The organisms were primarily gram-negative rods representing 9 taxa and 37 biotypes Pseudomonas spp. were the most common isolates.

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

New Chromosomal AmpC β-Lactamase in Enterobacter cloacae [PDF]

Antimicrobial Agents and Chemotherapy, 2004
Several members of the Enterobacteriaceae, including Enterobacter spp., are naturally resistant to amoxicillin and cephalosporins. Enterobacter cloacae produces chromosomally encoded β-lactamases, also called cephalosporinases (1), and is a serious nosocomial pathogen, the third most prevalent bacterium isolated in intensive care settings (5, 8).

Screening of Tetracycline’s Resistance Genes among Enterobacter cloacae and Citrobacter spp. isolates [PDF]

BIO Web of Conferences
There has been a growing prevalence of tetracycline-resistant bacteria across many species and genera. As a consequence, the efficacy of tetracycline treatment has diminished with time.

Structural and Functional Aspects of Class A Carbapenemases. [PDF]

, 2016
The fight against infectious diseases is probably one of the greatest public health challenges faced by our society, especially with the emergence of carbapenem-resistant gram-negatives that are in some cases pan-drug resistant.

Characteristics of Enterobacter cloacae prosthetic joint infections

Médecine et Maladies Infectieuses, 2019
Enterobacter cloacae prosthetic joint infections (PJI) are rare and poorly documented.We conducted a retrospective and monocentric study in an orthopedic unit supporting complex bone and joint infections. Between 2012 and 2016 we collected background, clinical, biological, and microbiological data from 20 patients presenting with prosthetic joint ...

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

A new oxathiolane from Enterobacter cloacae

Natural Product Research, 2014
Enterobacter cloacae is a versatile bacterial species inhabiting a wide variety of niches and is capable of metabolising a wide variety of substances as energy resources. The fermentation culture of this bacterial species has successfully yielded one new compound, Rimboxa (1) and three known compounds, i.e.
