Antimicrobial susceptibility of Campylobacter jejuni and Campylobacter fetus subsp. fetus to eight cephalosporins with special reference to species differentiation

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.

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...

Isolation of Campylobacter fetus subsp. jejuni from migratory waterfowl.

Since the sources from which humans acquire Campylobacter enteritis are only partially known, we studied the frequency of carriage of Campylobacter fetus subsp. jejuni in migratory waterfowl. Cecal contents of various species of wild ducks were cultured on selective media that contained antibiotics to inhibit normal flora. Thirty-five percent of the 445 ducks cultured harbored C. fetus subsp. j...
