Helicobacter pylori infection is the most common infectious disease worldwide. It is associated with duodenal and gastric ulcer disease and the risk of gastric neoplasia. The management of helicobacter pylori infection currently represents a real challenge for clinicians, given the ever-increasing rate of resistance of Helicobacter pyolori to various antibiotics.

Nosocomial infections: current situation in a resuscitation-unit.

Background: The nosocomial infection (NI) is defined as an infection that is not present or incubating on admission in establishment of care. It can be caused by the patient's germs, care personnel or hospital environment. Multidrug resistant (MDR) bacteria are particularly common in intensive care units that lead to a serious infections and increase morbidity, mortality and cost of care.

Clonal Spread of Colistin-Resistant Klebsiella pneumoniae Coproducing KPC and VIM Carbapenemases in Neonates at a Tunisian University Hospital.

In this study, we have attempted to report the first clonal spread of colistin-resistant Klebsiella pneumoniae coproducing KPC and VIM carbapenemases in the neonatal unit of Rabta Teaching Hospital of Tunis (Tunisia). This retrospective study was performed from January 1, 2014 to December 31, 2014 in the Microbiology Laboratory at the Rabta University Hospital of Tunis. Twenty-one nonreplicate colistin-resistant K.

Multiple and mixed Helicobacter pylori infections: Comparison of two epidemiological situations in Tunisia and France.

Individuals can be infected by either a single or multiple strains of Helicobacter pylori. Multiple infection with genetically different isolates and particularly mixed infection with both antibiotic-susceptible and resistant isolates are difficult to detect and should impact the effectiveness of eradication treatment. It is largely assumed that multiple infections are more frequent in developing countries but an actual comparison developing/developed using a single methodology has never been reported.

Genotypic and phenotypic characteristics of tunisian isoniazid-resistant Mycobacterium tuberculosis strains.

Forty three isoniazid (INH)-resistant Mycobacterium tuberculosis isolates were characterized on the basis of the most common INH associated mutations, katG315 and mabA -15C→T, and phenotypic properties (i.e. MIC of INH, resistance associated pattern, and catalase activity).

Primary resistance to clarithromycin, metronidazole and amoxicillin of Helicobacter pylori isolated from Tunisian patients with peptic ulcers and gastritis: a prospective multicentre study.

Background: The frequency of primary resistance to antibiotics in H. pylori isolates is increasing worldwide. In Tunisia, there are limited data regarding the pattern of H.

Prevalence of Helicobacter pylori vacA, cagA, iceA and oipA genotypes in Tunisian patients.

Background: Distinct virulence factors of H. pylori have been described: the vaculating cytotoxin (vacA), the cytotoxin associated gene (cagA), the induced by contact with epithelium factor Antigen (iceA gene) and the outer membrane protein oipA. In Tunisia, there are no data regarding the pattern of H.

Characterization of Tunisian Mycobacterium tuberculosis rifampin-resistant clinical isolates.

Analysis of the gene encoding the beta-subunit of Mycobacterium tuberculosis RNA polymerase (rpoB) has demonstrated a small region that harbors the mutations most frequently associated with rifampin resistance. In this study, we determined the occurrence of rifampin resistance in 544 Tunisian clinical M. tuberculosis strains isolated in a university hospital between 2004 and 2006 by using the standard-proportion agar method, the INNO-LiPA Rif.
