Invasive aspergillosis (IA) caused by Aspergillus flavus remains poorly described. We retrospectively analyzed 54 cases of IA caused by A. flavus reported in France during 2012-2018.

To elucidate the epidemiology of Sarcocystis spp. parasites in human intestinal infections, we used high-throughput sequencing to investigate human intestinal sarcocystosis cases identified by microscopy in France during 2021-2024. Our results indicate that humans are a definitive host of S.

Unlabelled: Intestinal microsporidiosis caused by is an opportunistic infection that especially affects solid organ transplant (SOT) recipients. Management revolves around tapering the immunosuppressive regimen and/or using a specific anti-microsporidia treatment, but only fumagillin has demonstrated efficacy for treatment of this infection. Since fumagillin has been commercially discontinued, nitazoxanide is increasingly being used in this indication.

This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

Objectives: We aimed to describe features and outcomes of cryptococcosis among HIV-seronegative individuals in a large surveillance network for cryptococcosis in France.

Methods: We included incident cases of cryptococcosis in HIV-seronegative individuals from 2005 to 2020. We compared patient characteristics, disease presentations, cryptococcal antigen results, and induction antifungal treatments according to underlying disease.

Among 1107 cryptococcosis cases from the French surveillance network (2005-2020), the proportion of HIV-seronegative individuals has recently surpassed that of HIV-seropositive individuals. We observed marked differences in patient characteristics, disease presentations, cryptococcal antigen results, infecting species, and mortality according to HIV serostatus.

Diagnosing neurocysticercosis (NCC) is difficult due to its variable clinical presentations and the different imaging techniques used to detect brain damage. This study aimed to evaluate the use of cerebrospinal fluid serology and PCR for diagnosing biological neurocysticercosis in a non-endemic country. We tested samples from patients living in France with suspected NCC and confirmed that 45 of the patients presented with the disease.

Intestinal microsporidiosis is most often caused by , and to a lesser extent by species of the genus . Until now, was not clearly known to induce disease restricted to the intestine, or rarely in HIV subjects or in tropical countries. We report here 11 cases of delineated intestinal microsporidioses due to diagnosed in France in non-HIV patients.

Article Synopsis
  • * This recombinant protein vaccine works by triggering both humoral and cell-mediated immune responses, offering moderate efficacy against the disease.
  • * While the recommendation has brought hope for malaria control in children, the timeline for its widespread adoption in high-transmission countries remains uncertain.

Objectives: To determine the epidemiological cut-off values (ECVs) of ten antifungal agents in a wide range of yeasts and Aspergillus spp. using gradient concentration strips.

Methods: The minimum inhibitory concentrations for amphotericin B, anidulafungin, caspofungin, micafungin, flucytosine, fluconazole, itraconazole, isavuconazole, posaconazole, and voriconazole, determined with gradient concentration strips at 35 French microbiology laboratories between 2002 and 2020, were retrospectively collected.

Background: Cases of Toxoplasma reactivation or more severe primary infection have been reported in patients receiving immunosuppressive (IS) treatment for autoimmune diseases (AID). The purpose of this study was to describe features of toxoplasmosis occurring in patients with AID treated by IS therapy, excluded HIV-positive and transplant patients.

Methods: A multicenter descriptive study was conducted using data from the French National Reference Center for Toxoplasmosis (NRCT) that received DNA extracts or strains isolated from patients, associated with clinical data.

Cryptococcosis is the third most common cause of invasive fungal infection in solid organ transplant recipients and cryptococcal meningitis (CM) its main clinical presentation. CM outcomes, as well as its clinical features and radiological characteristics, have not yet been considered on a large scale in the context of kidney transplantation (KT). We performed a nationwide retrospective study of adult patients diagnosed with cryptococcosis after KT between 2002 and 2020 across 30 clinical centers in France.

Unlabelled: Although Candida spp are aerobic microorganisms, some Candida strains, mainly Candida glabrata, can be recovered from anaerobic blood culture vials. We assessed the contribution of the anaerobic vials for the diagnosis of candidemia, especially for C. glabrata.

Article Synopsis
  • Invertebrates have become valuable models for studying complex interactions between hosts and microbes, particularly for understanding pathogenic fungi.
  • The larvae of certain invertebrates provide a reliable system to analyze the disease-causing abilities and factors of various fungal strains.
  • The review discusses different methods for assessing fungal pathogenicity, summarizes mutants tested for virulence, and suggests that while invertebrate models are useful, mammalian models may still be needed for validation.

  • Traveler's diarrhea is a common health issue for tourists, often resulting from bacterial and parasitic infections.
  • Most cases are self-limiting, but they may require medical attention if complications arise.
  • The article emphasizes the importance of recognizing symptoms, understanding treatment options, and providing health education to prevent diarrhea during travel.

(Af) and (Sm) are pathogenic microorganisms, which coexist in the respiratory tract of cystic fibrosis (CF) patients. We recently developed an model of mixed biofilm associating Af ATCC 13073-GFP (Af13073) and Sm ATCC 13637 (Sm13637) and described an antibiosis effect. The present study aim was to assess the antibiosis of Sm on Af using different strains and to analyze the potential synergistic virulence of these strains in an model.
