title: Bacteraemic pneumonia caused by Neisseria lactamica with reduced susceptibility to penicillin and ciprofloxacin in an adult with liver cirrhosis.
abstract: This report presents a case of bacteraemic pneumonia caused by Neisseria lactamica in an adult patient with liver cirrhosis who was successfully treated with ceftriaxone. The isolate was confirmed as N. lactamica by analysis of a partial sequence of the 16S rRNA gene; it had reduced susceptibilities to penicillin (MIC 0.75 microg ml(-1)) and ciprofloxacin (MIC > or =0.5 mg l(-1)).
