Bordetella hinzii Pneumonia in Patient with SARS-CoV-2 Infection.

Patients infected with severe acute respiratory syndrome coronavirus 2 might have bacterial and fungal superinfections develop. We describe a clinical case of coronavirus disease with pulmonary aspergillosis associated with Bordetella hinzii pneumonia in an immunocompetent patient in France. B.

[Mycoplasma genitalium: Prevalence of macrolide and fluoroquinolone resistance at the University Hospital of Tours, and check of the S-DiaMGRes (Diagenode Diagnostics) assay].

Mycoplasma genitalium is an emerging agent of sexually transmitted infections, associated with urethritis, cervicitis, and pelvic inflammatory disease. Over the past decade, a remarkable increase in macrolide-resistant M. genitalium, the first-line treatment, is observed all over the world.

[Positive HBs antigen in the absence of hepatitis B virus infection].

French recommendations for the screening of hepatitis B virus (HBV) infection were updated in 2019 with the association of three markers: HBs Ag, anti-HBs Ab and anti-HBc Ab. These three markers allow identification of infected patients, vaccinated patients and patients who have been in contact with HBV. A positive HBs Ag is usually associated with HBV infection but this interpretation must take into account the clinical context.

Combination of β-(1, 3)-D-glucan testing in serum and qPCR in nasopharyngeal aspirate for facilitated diagnosis of Pneumocystis jirovecii pneumonia.

Background: Currently, the biological diagnosis of Pneumocystis jirovecii pneumonia (PjP infection) usually relies on microbiological investigations in bronchial-alveolar lavage fluid (BALF) by conventional staining methods and/or molecular biology. However, bronchial-alveolar lavage is sometimes complicated to manage, especially in weakened patients. Therefore, alternative clinical samples-easier to collect-are warranted in such specific contexts.
