Antimicrobial Susceptibility Testing of 59 Strains of Campylobacter fetus subsp. fetus

Antimicrobial susceptibility testing of 59 strains of Campylobacter fetus subsp. fetus.

The susceptibilities of 59 Campylobacter fetus subsp. fetus isolates to eight antibiotics were studied by the agar dilution, E-test, and disk diffusion methods. None of the isolates were beta-lactamase producers. All were susceptible to ampicillin, gentamicin, imipenem, and meropenem as determined by the three methods, with MICs at which 90% of the isolates are inhibited (MIC90s) (determined by...

Susceptibility of Campylobacter fetus subsp. jejuni to twenty antimicrobiol agents.

One hundred recent clinical isolates of Campylobacter fetus subsp. jejuni were tested by an agar dilution technique for susceptibility to each of 20 antimicrobial agents. Doxycycline and gentamicin were the most active of the drugs examined, inhibiting all strains at concentrations achievable in serum. Although the median minimal inhibitory concentration of erythromycin was low, 8% of the isola...

Susceptibility of Campylobacter fetus subsp. jejuni to twenty-nine antimicrobial agents.

The activity of 29 antimicrobial agents was tested against 95 strains of Campylobacter fetus subsp. jejuni isolated from human stools. Furazolidone and gentamycin were the most active agents. The tetracyclines, erythromycin, and chloramphenicol were very active against most of the strains, but with each antibiotic a few resistant strains were found. The penicillins were relatively inactive, and...

Susceptibility of Campylobacter fetus subsp. jejuni, isolated from patients in Jakarta, Indonesia to ten antimicrobial agents.

Isolation of Campylobacter fetus subsp. fetus from a patient with cellulitis.

Campylobacter fetus subsp. fetus is a gram-negative, slender, spirally curved bacterial pathogen. It has been isolated from human blood, spinal fluid, and abscesses, but cellulitis associated with bacteremia is rare. We report its isolation from a blood culture of a human patient with cellulitis as well as difficulties encountered in determining the identity of the subspecies of C. fetus.
