SUMMARY The World Health Organization has established a fungal priority pathogens list that includes species critical or highly important to human health. Among them is the order Mucorales, group comprising at least 39 responsible for life-threatening infection known as mucormycosis. Despite continuous rise in cases and poor prognosis due innate resistance most antifungal drugs used clinic, Mucorales received limited attention, partly because of difficulties performing genetic manipulations. COVID-19 pandemic further escalated cases, with some patients experiencing COVID-19-associated mucormycosis, highlighting urgent need increase knowledge about these fungi. This review addresses significant challenges treating disease, including delayed diagnosis, lack accurate global incidence estimation, treatment options. Furthermore, it focuses on recent discoveries regarding mechanisms genes involved development resistance, host defense response. Substantial advancements have been made identifying key invasion tissue damage, receptors exploited by fungus invade tissues, resistance. expected pave way new antifungals combat In addition, we anticipate progress characterizing biology, particularly pathogenesis possibilities offered CRISPR-Cas9 technology manipulation previously intractable species.

Coinfection is defined as the occurrence of at least two genetically distinct infectious agents within same host. Historically, fungal infections have been neglected, leading to an underestimation their impact on public health systems. However, coinfections become increasingly prevalent, emerging a significant global concern. This review explores commonly associated with HIV, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza, Mycobacterium tuberculosis, and Pseudomonas species. These include candidiasis, aspergillosis, paracoccidioidomycosis, cryptococcosis, histoplasmosis, pneumocystosis, sporotrichosis, mucormycosis. We discuss key local systemic mechanisms that contribute these coinfections. HIV infects CD4+ cells, causing immunosuppression, particularly impairing adaptive immune response. The inflammatory response SARS-CoV-2 infection disrupts both pulmonary homeostasis, rendering individuals more vulnerable disseminated Severe influenza promotes by triggering production pro-inflammatory cytokines, which damage epithelial-endothelial barrier impair recognition phagocytosis cells. Tuberculosis can replace normal lung parenchyma collagen tissue, alterations in architecture, compromising its function. Interaction between Aspergillus during coinfection involves competition for iron availability deprivation. Therefore, specific interactions each underlying disease are detailed this review. In addition, we highlight risk factors coinfections, pathophysiology, epidemiology, challenges early diagnosis. Recognizing substantial worldwide burden posed crucial improve survival rates.

COVID-19-associated rhino-orbital mucormycosis has become a new clinical entity. This study’s aim was to evaluate the histopathological and ultramicroscopic morphological aspects of this fungal infection. an observational retrospective study on eight patients from three tertiary centers in Romania. The tissue samples collected during functional endoscopic sinus surgery were studied through examination, scanning electron microscopy, transmission microscopy. In characteristic all cases identified: wide aseptate hyphae with right-angle ramifications, which invade blood vessels. One case presented perineural invasion into lymphatics. And another case, mucormycosis–aspergillosis coinfection identified.

Endodontic-periodontal (endo-perio) lesions are commonly encountered in dental clinics, with patients typically presenting acute pulpal pain, often accompanied by abscess formation and tooth mobility. Management generally involves root canal treatment (RCT) and, if required, surgical intervention. This article discusses a notable case of 43-year-old male patient who presented chief complaint pain loose teeth the upper left back region for past 3 weeks. Phase I periodontal therapy was initiated, followed RCT #21 to #25. However, 2 weeks later, swelling, prompting excision biopsy. Histopathological analysis revealed nonseptate hyphae right-angle branching, indicative mucormycosis.

In March 2020, the World Health Organization (WHO) declared COVID-19 outbreak a global pandemic, beginning of worldwide health crisis that revealed numerous medical challenges healthcare systems and pandemic emergency strategies.Among these challenges, mucormycosis, typically rare fungal infection, gained attention. With an average incidence about 2 per 1 million people, mucormycosis is considered very disease, opportunistic infection mostly affecting lungs or skin soft tissues immunocompromised patients. Poorly controlled diabetes mellitus one leading risk factors rhino-orbital mucormycosis. Countries with high prevalence limited resources have higher rates, India Pakistan being among nations particularly incidences.During second wave India, rates surged dramatically within few weeks, over 47,500 cases COVID-19-associated (CAM) reported between May August 2021. Mucormycosis characterized by mortality rate up to 90%, especially when diagnosis delayed, treatment commences late.
