Fosfomycin is a synthetic, broad-spectrum, bactericidal antibiotic with in vitro activity against large numbers of gram-negative and gram-positive organisms including E. coli, Klebsiella spp, Proteus spp, Pseudomonas spp, and VRE. It does not have activity against Acinetobacter.

What is the best antibiotic for Proteus mirabilis UTI?

The most appropriate treatment for P. mirabilis may be aminoglycosides, carbapenems (except imipenem), and 3rd generation cephalosporins. Recent P. mirabilis isolates were also mostly susceptible to augmentin, ampicillin-sulbactam, and piperacillin/tazobactam.

What infection does fosfomycin treat?

Fosfomycin is used to treat urinary tract infection and cystitis (bladder infection) in women. This medicine is an antibiotic. It works by killing bacteria or preventing their growth. However, this medicine will not work for colds, flu, or other virus infections.

What bacteria are sensitive to fosfomycin?

Considerable rates of susceptibility to fosfomycin were found for Proteus mirabilis, Klebsiella pneumoniae, Pseudomonas aeruginosa (including the respective carbapenem-resistant isolates), and Enterobacter spp., as well as Enterococcus faecalis and E. faecium.

Is fosfomycin effective against Enterococcus?

Fosfomycin demonstrates good in vitro activity against enterococci, including VRE strains (7–10), and is licensed for the treatment of uncomplicated UTIs as a single 3 g oral dose, which is well tolerated and achieves high concentrations in the urine (11–14).

Does fosfomycin cover Enterococcus faecalis?

Fosfomycin tromethamine is a phosphonic acid antibacterial agent that has been approved in the USA for the treatment of uncomplicated urinary tract infections due to Escherichia coli and Enterococcus faecalis.

Does Cipro treat Proteus mirabilis?

CIPRO is indicated in adult patients for treatment of urinary tract infections caused by Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Serratia marcescens, Proteus mirabilis, Providencia rettgeri, Morganella morganii, Citrobacter koseri, Citrobacter freundii, Pseudomonas aeruginosa, methicillin- …

Is Proteus mirabilis sensitive to fosfomycin?

Specifically, fosfomycin was active against almost all tested S. aureus, Coagulase negative staphylococcal isolates and Enterococcus spp. Considerable rates of susceptibility to fosfomycin were found for E. coli, Proteus mirabilis, Pseudomonas aeruginosa as well as Klebsiella pneumoniae.

Is Proteus mirabilis susceptible to fosfomycin?

What antibiotics treat Enterococcus faecalis UTI?

Ampicillin is the preferred antibiotic used to treat E. faecalis infections. Other antibiotic options include: daptomycin.

Can fosfomycin be used to treat acute prostatitis?

Once again, the most common adverse reaction was gastrointestinal, including fecal urgency and diarrhea refractory to loperamide with twice daily dosing. These case reports suggest that fosfomycin can also be used in acute prostatitis.

Does fosfomycin work against Klebsiella pneumoniae?

Fosfomycin has good in vitro activity against common uropathogens, such as Escherichia coli (including extended-spectrum β-lactamase-producing E. coli), Proteus mirabilis, Klebsiella pneumoniae and Staphylococcus saprophyticus, and the susceptibility of uropathogens to fosfomycin has remained relatively stable over time.

How effective is fosfomycin against Enterobacter infections?

Fosfomycin showed relatively good activity against Proteus isolates which are primarily resistant to nitrofurantoin (82.5% of isolates were susceptible to fosfomycin). Additionally, E. coli, K. pneumoniae and Enterobacter species isolates resistant to nitrofurantoin remained susceptible to fosfomycin, between 78.6% and 88.1%.

What bacteria does funfosfomycin kill?

Fosfomycin exhibits in vitro activity against both gram-negative and gram-positive bacteria including E. coli, Enterococcus faecalis, Enterococcus faecium, Citrobacter diversus, Citrobacter freundii, Enterobacter aerogenes, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris and Serratia marcescens [2,5].
