Nec rotizing Fasciitis Necrotizing fasciitis has been well-described in neutropenic and diabetic hosts 129. Burn sepsis is typically associated with positive blood cultures and significant morbidity and mortality.
Other key biochemical characteristics include oxidation of glucose but not disaccharide, hydrolysis of acetamide, and reduction of nitrates to nitrogen gas.
The growth in tissue depends on its ability to resist ingestion by neutrophils.
Three mechanisms of resistance predominate: production of beta-lactamases, loss of outer membrane proteins, and upregulation of efflux pumps. Antibiotic resistance is currently one of the most important problems faced by caregivers, especially in cystic fibrosis patients.
Microbiology data at completion of the phase 3 trials of inhaled tobramycin demonstrated some decrease in susceptibility of P. The number of strains defined as resistant according to standard criteria increased in the tobramycin group, although there is no evidence of selection of the most resistant isolates to become the most prevalent.
Currently studies are monitoring resistance patterns of bacteria isolated in cystic fibrosis sputum to determine the impact of years of chronic intermittent inhaled tobramycin.
Both chromosomally-mediated and plasmid-mediated beta-lactamases characteristically produce AmpC-type which mediate resistance to the third generation cephalosporins and the monobactam, aztreonam.
In the year . The European Association of Urology and the Infectious Diseases Society of America list fosfomycin as first-line therpay for uncomplicated cystitis in women, despite it might be slightly less efective than other agents.
Nitrofurantoin Nitrofurantoin, belonging to a group of synthetic nitrofuran, was initially introduced as a microcrystalline form.
In 1967 a macrocrsitalline form with improved gastrointetinal tolerance became available. The mechanisms of bacterial activity appears to involve multiple sites, including inhibition of ribosomal translation, bacterial DNA damage, and interference with the Krebs cycle.
However, Proteus, Serratia and Pseudomonas have natural resistance to nitrofurantoin. In earlier non comparative studies bacteriologic and clinical responses in patietns with acute uncomplicated cystitis ranged from 61 to 100 percent.
