RESUMEN
Listeria monocytogenes is a very important life-threatening bacteria in certain risk groups such as neonates, pregnant women, elderly people, transplant recipients and others with impaired cell-mediated immunity. However, its infections are very rare in healthy children. Reports of listeriosis in newborn period are limited. We report a case of neonatal listeriosis with erythematous rash, intractable convulsions, severe early neonatal sepsis, disseminated intravascular coagulation, multiple organ dysfunction syndrome and death. Although an empirical antibiotic therapy including ampicillin (semisentetic penicillin) and aminoglycoside combination is effective by the means of a probable Listeria infection, the progression of the very early-onset disease may be fatal, despite vigorous treatment efforts as in our case.

SETTING: The Microbiology and Clinical Microbiology Department, Gulhane Military Medical Academy, Ankara, Turkey, a tertiary referral hospital in a region endemic for tuberculosis. OBJECTIVE: To evaluate rifampicin resistance of Mycobacterium tuberculosis complex strains using FASTPlaqueTB-RIF, a rapid and novel bacteriophage-based susceptibility technique. DESIGN: Results of isolates tested with the BACTEC 460 TB system were compared with FASTPlaqueTB-RIF. RESULTS: Susceptibility to rifampicin of M. tuberculosis complex isolates was tested for 88 isolates using FASTPlaqueTB-RIF. Sixty-seven isolates were susceptible and 21 were resistant to rifampicin using the BACTEC 460 TB system. Overall accuracy for FASTPlaqueTB-RIF was 94.3% (95%CI 87.3-97.5) for the detection of rifampicin susceptibility. The sensitivity and specificity of FASTPlaqueTB-RIF were respectively 100.0% (95%CI 84.5-100) and 92.5% (95%CI 83.6-96.7). CONCLUSION: This study demonstrates that FASTPlaqueTB-RlFM is a rapid and inexpensive test which has a good correlation with the BACTEC 460 TB system.
