Molecular and phylogeographic studies have led to the definition within the Mycobacterium tuberculosis complex (MTBC) of a number of geotypes and ecotypes showing a preferential geographic location or host preference. The MTBC is thought to have emerged in Africa, most likely the Horn of Africa, and to have spread worldwide with human migrations. Under this(More)
The objective of this study was to determine the genetic diversity of multidrug-resistant (MDR) Pseudomonas aeruginosa strains isolated over a period of 12 months in two French hospitals and to test their susceptibility to bacteriophages. A total of 47 MDR isolates recovered from hospitalized patients were genotyped using multiple-locus variable number of(More)
BACKGROUND Infections by A. calcoaceticus-A. baumannii (ACB) complex isolates represent a serious threat for wounded and burn patients. Three international multidrug-resistant (MDR) clones (EU clone I-III) are responsible for a large proportion of nosocomial infections with A. baumannii but other emerging strains with high epidemic potential also occur.

Since the first discovery of the smooth tubercle (SmTB) bacilli "Mycobacterium canettii" less than 60 isolates have been reported, all but one originating from a limited geographical location, the Horn of Africa. In spite of its rarity, the SmTB lineage deserves special attention. Previous investigations suggested that SmTB isolates represent an ancestral(More)
A strain of Nocardia was isolated from a pulmonary abscess of a human immunodeficiency virus-infected patient in France. Comparative 16S rRNA gene sequence analysis revealed that the isolate represented a strain of Nocardia beijingensis. Antimicrobial susceptibility testing was essential to guide the clinicians to successfully treat this infection.
“Mycobacterium canettii,” an opportunistic human pathogen living in an unknown environmental reservoir, is the progenitor species from which Mycobacterium tuberculosis emerged. Since its discovery in 1969, most of the ≈70 known M. canettii strains were isolated in the Republic of Djibouti, frequently from expatriate children and adults. We show here, by(More)
INTRODUCTION The Republic of Djibouti is an African country that exhibits one of the highest incidence rate of tuberculosis in the world. The aim of this study was to evaluate the prevalence of multidrug-resistant tuberculosis among new cases. METHODOLOGY We studied retrospectively every tuberculosis case diagnosed over a 12-month period in patients(More)
Successful control of tuberculosis relies on the rapid detection of Mycobacterium tuberculosis. Few chromatographic lateral flow assays for the discrimination of the M. tuberculosis complex were developed from culture media. We compared the values of 2 assays to assess their place in diagnosis of tuberculosis. We conclude of their efficiency and relevance(More)
OBJECTIVES The aim of this study was to compare the efficiency of two commercial assays, INNO-LiPA Rif.TB and MTBDRplus, for the identification of mutations in the rpoB hot-spot region and to assess the efficiency of these mutations in conferring resistance to rifampicin. METHODS A collection of 126 rifampicin-resistant Mycobacterium tuberculosis and(More)
BACKGROUND  Invasive wound mucormycosis (IWM) is associated with an extremely poor outcome among critically ill burn patients. We describe the detection of circulating Mucorales DNA (cmDNA) for the early diagnosis of IWM in those patients and report the potential value of detecting cmDNA for treatment guidance. METHODS  Severely ill burn patients admitted(More)
