It Takes Two to Tango: How a Dysregulation of the Innate Immunity, Coupled With Virulence, Triggers VVC Onset.

Front Microbiol 2021 7;12:692491. Epub 2021 Jun 7.

Department of Surgical, Medical, Dental and Morphological Sciences with Interest in Transplant, Oncological and Regenerative Medicine, University of Modena and Reggio Emilia, Modena, Italy.

Vulvovaginal candidiasis (VVC) is a symptomatic inflammation of the vagina mainly caused by . Other species, such as , , , and , are mainly associated to the recurrent form of the disease (RVVC), although with a lower frequency. In its yeast form, is tolerated by the vaginal epithelium, but switching to the invasive hyphal form, co-regulated with the expression of genes encoding virulence factors such as secreted aspartyl proteases (Sap) and candidalysin, allows for tissue damage.

Rapid proliferation due to better metabolic adaptation results in full virulence of a filament-deficient Candida albicans strain.

Nat Commun 2021 Jun 23;12(1):3899. Epub 2021 Jun 23.

Research Group Microbial Immunology, Leibniz Institute for Natural Product Research and Infection Biology - Hans Knoell Institute, Beutenbergstraße 11a, Jena, Germany.

The ability of the fungal pathogen Candida albicans to undergo a yeast-to-hypha transition is believed to be a key virulence factor, as filaments mediate tissue damage. Here, we show that virulence is not necessarily reduced in filament-deficient strains, and the results depend on the infection model used. We generate a filament-deficient strain by deletion or repression of EED1 (known to be required for maintenance of hyphal growth). Read More

Distinct innate immune responses between sublethal and lethal models of disseminated candidiasis in newborn BALB/c mice.

Microb Pathog 2021 Jun 19:105061. Epub 2021 Jun 19.

Departamento de Microbiología, Universidad Autónoma de Nuevo León, Facultad de Medicina y Hospital Universitario "Dr. José Eleuterio González", Av. Francisco I. Madero, Mitras Centro, 64460, Monterrey, Mexico. Electronic address:

Invasive candidiasis is associated with a high incidence and mortality rates in infants, especially in preterm newborns. The immunopathogenesis of the mycosis during the neonatal period is poorly understood. Although several in vivo models exist to study invasive candidiasis, the majority of studies employ distinct routes of infection and use 2 to 6 day-old mice that could be less comparable in studying candidiasis in preterm infants.

Albumin Neutralizes Hydrophobic Toxins and Modulates Pathogenicity.

mBio 2021 Jun 22:e0053121. Epub 2021 Jun 22.

Junior Research Group Adaptive Pathogenicity Strategies, Leibniz Institute for Natural Product Research and Infection Biology, Hans Knöll Institute, Jena, Germany.

Albumin is abundant in serum but is also excreted at mucosal surfaces and enters tissues when inflammation increases vascular permeability. Host-associated opportunistic pathogens encounter albumin during commensalism and when causing infections. Considering the ubiquitous presence of albumin, we investigated its role in the pathogenesis of infections with the model human fungal pathogen, Candida albicans. Read More

Diagn Microbiol Infect Dis 2021 May 17;101(1):115431. Epub 2021 May 17.

Department of Medical Microbiology, Haaglanden Medical Center, The Hague, The Netherlands.

Abnormal vaginal discharge may be caused by bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis and/or aerobic vaginitis. For the development of a diagnostic algorithm, tree-based classification analysis was performed on symptoms, signs and bedside test results of 56 patients, and laboratory tests (culture, Nugent score, qPCRs) were compared. Amplicon sequencing of the 16S rRNA gene was used as reference test for bacterial vaginosis and aerobic vaginitis, culture for vulvovaginal candidiasis and qPCR for trichomoniasis. Read More

[Mucormycosis: Current and future management perspective].

Rev Iberoam Micol 2021 Jun 15. Epub 2021 Jun 15.

Unidad de Enfermedades Infecciosas (Área Clínica Médica), Hospital Universitario y Politécnico La Fe, Valencia, España. Electronic address:

Infections caused by mucorales, with an increasing incidence after candidiasis and aspergillosis, are characterized by the fast angioinvasion of blood vessels and invasion of neighboring organs or structures. Mucorales most commonly cause rhinocerebral, pulmonary, cutaneous, digestive or disseminated infections, and their spread is favored by certain underlying diseases (diabetes, kidney failure) and risk factors (neutropenia, immunosuppression, iron overload). These infections have a high mortality rate, over 40% in many series, and the key to their cure depends on both an early diagnosis and an antifungal treatment, associated in most cases with extensive surgical debridement and other adjunctive therapies.

Extracellular Nucleic Acids Present in the Biofilm Trigger the Release of Neutrophil Extracellular Traps.

Front Cell Infect Microbiol 2021 26;11:681030. Epub 2021 May 26.

Department of Comparative Biochemistry and Bioanalytics, Faculty of Biochemistry, Biophysics and Biotechnology, Jagiellonian University, Krakow, Poland.

Neutrophils, the first line of the host's defense, use a variety of antimicrobial mechanisms to fight invading pathogens. One of the most crucial is the production of neutrophil extracellular traps (NETs) in the process called NETosis. The unique structure of NETs effectively inhibits the spread of pathogens and ensures their exposure to a high concentration of NET-embedded antimicrobial compounds. Read More
