The nonfermenting gram-negative bacteria are a group of aerobic, non–spore-forming bacilli that either do not use carbohydrates as a source of energy or degrade them through metabolic pathways other than fermentation.10,21 Unlike the Enterobacteriaceae, the nonfermenting gram-negative ...

This is a newcomer among gram-negative infections, not likely to be diagnosed unless one has been informed of its existence. Clinically it looks like stage II or III rosacea. Multiple tiny yellow pustules increase suspicion. Neither oral antibiotics nor metronidazole will control the disease. The ...

(iii) Loss of the rod cap in ∆flhE strains enables the assembly of hook subunits, followed by flagellin assembly leading to periplasmic flagellar filament formation. Full size image Discussion The flagellar structure of Gram-negative bacteria are composed of several thousands of building blocks, ...
Holin-like protein secretion systems (also named Type 10 Secretion Systems, TXSSs) were also reported in Gram-negative bacteria, mediating the transport of specific proteins into extracellular milieu from periplasm [42]. The systems are different from T2SSs and the two types of secretion systems ...
This is a differential medium. It tests an organism’s ability to ferment the sugar glucose as well as its ability to convert the end product of glycolysis, pyruvic acid into gaseous byproducts. This is a test commonly used when trying to identify Gram-negative enteric bacteria, all of which...
Gazing upon the fixed and stained slide under the microscope revealed it to be a series of circular shaped cells in a chain-like pattern. This, along with the purple color, deemed it to be Gram-positive streptococci. The negative catalase test confirmed the streptococci shape and arrangement ...
His sputum sample yielded a weakly oxidase-positive, gram-negative rod, that was gentamicin and colistin resistant and was reported as Pseudomonas spp. He was given anti-pseudomonas antibiotics but recovered slowly. Since then he had several exarcerbations with gram-negative rods that were reported...
