Evaluation of Phenotypic Tests for Carbapenemase Detection in Enterobacteriaceae in Tunisia.

Resistance to carbapenems in Enterobacteriaceae is a challenge for public health. Carbapenemase production is the leading mechanism. This work aims to evaluate four phenotypic methods for carbapenemase detection in comparison with a molecular method.

Molecular epidemiology of a Streptococcus pneumoniae serotype 1 outbreak in a Tunisian jail.

The microbiologic investigations of an outbreak implicating 17 inmates demonstrated the spread of a pneumococcal serotype 1 clone not only in this jail but also in the area of Tunis. This clone, which is fully susceptible to antibiotics but not included in the heptavalent conjugate vaccine, should be closely monitored.
