The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
Treatment of such infections can be difficult due to multiple antibiotic resistance, [4] and in the United States, there was an increase in MDRPA (Multidrug-resistant Pseudomonas aeruginosa) resistant to ceftazidime, ciprofloxacin, and aminoglycosides, from 0.9% in 1994 to 5.6% in 2002. [5]
The organisms causing endogenous infections are generally gram negative bacilli such as Enterobacteriaceae (i.e. Escherichia coli, Klebsiella pneumoniae, Proteus spp. ), and Pseudomonas aeruginosa. Exposure to higher doses of radiation is associated with systemic anaerobic infections due to gram negative bacilli and gram positive cocci. Fungal ...
Ciprofloxacin is a fluoroquinolone antibiotic used to treat a number of bacterial infections. [5] This includes bone and joint infections, intra-abdominal infections, certain types of infectious diarrhea, respiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others. [5]
This phenomenon can be used to select against resistant bacteria using an approach termed collateral sensitivity cycling, which has recently been found to be relevant in developing treatment strategies for chronic infections caused by Pseudomonas aeruginosa. [236]
Treatment of P. aeruginosa infections can be difficult due to its natural resistance to antibiotics. When more advanced antibiotic drug regimens are needed adverse effects may result. It is citrate, catalase, and oxidase positive.
Based upon a number of different observations, including that the gram-positive bacteria are the most sensitive to antibiotics and that the gram-negative bacteria are, in general, resistant to antibiotics, it has been proposed that the outer cell membrane in gram-negative bacteria (diderms) evolved as a protective mechanism against antibiotic ...
Antibiotics cross the outer membrane of Pseudomonas and Acinetobacter approximately 100 times more slowly than they cross the outer membrane of Enterobacteriaceae, due in part to their use of porins that can adopt a conformation having a very restricted entry channel. Further, the porin levels may be down-regulated in response to antibiotic ...
