Emergomycosis is an endemic mycosis caused by the species. Infections due to this agent have been reported globally. Hence, the present systematic review on infections was conducted to study the disease epidemiology, underlying diseases and risk factors, causative agents, and treatment and outcome.

Objectives: Molecular genotyping of Trichosporon species using intergenic spacer region (IGS-1) sequencing and antifungal drug susceptibility testing of T. asahii clinical isolates from Indian patients.

Materials And Methods: Fifty-five Trichosporon strains were characterized using IGS-1 sequencing from 2006 to 2018 and tested against 5 antifungals using CLSI M27-A3 guidelines.

Article Synopsis
  • * The review analyzed 108 cases, revealing that most patients (67.6%) were treated with S. boulardii, while significant risk factors included ICU stays, nutritional support, gastrointestinal symptoms, and diabetes.
  • * The all-cause mortality rate was 36.1%, showing no significant difference between those on probiotics and those who weren't, highlighting a need for caution in using S. boulardii in vulnerable patients.

Article Synopsis
  • Candida auris, a multidrug-resistant fungus, saw a rise in infections among COVID-19 patients in ICUs during the pandemic, with a prevalence rate of 14% among 97 cases identified.* -
  • The most common underlying conditions in affected patients included diabetes (42.7%), hypertension (32.9%), and obesity (14.6%), with significant iatrogenic risks linked to ICU care and invasive procedures.* -
  • The overall mortality rate for C. auris infections was 44.4%, escalating to 64.7% for those with candidemia, highlighting the urgent need for improved infection control in healthcare settings.*

Coronavirus disease (COVID-19)-associated mucormycosis (CAM) is an emerging threat globally, especially in India. More than 40,000 CAM cases have been reported in India. The emergence of CAM cases in India has been attributed to environmental, host, and iatrogenic factors.

Background: Candida auris is an emerging multidrug resistant yeast which causes blood stream infection especially among critically ill patients. This yeast can also colonize patients and are isolated from hospital environment causing outbreaks in hospital settings.

Objective: To describe possible outbreak of C.

Mucormycosis is an angioinvasive disease caused by saprophytic fungi of the order Mucorales. The exact incidence of mucormycosis in India is unknown due to the lack of population-based studies. The estimated prevalence of mucormycosis is around 70 times higher in India than that in global data.

Histopathological examination (HPE) of tissue helps in the diagnosis of invasive fungal infections (IFIs) but cannot identify the fungus to the genus/species level Available protocols for the molecular identification of fungi from formalin-fixed and paraffin-embedded (FFPE) tissues have limitations in terms of extraction and target selection, and standardisation. Development of sequence-based fungal identification protocol after extraction of DNA from formalin-fixed and paraffin-embedded (FFPE) tissues. A total of 63 FFPE tissues from histopathology proven IFI cases were used to standardize the DNA extraction (commercial QIAamp kit-based extraction and conventional phenol-chloroform-isoamyl alcohol [PCI] method) and sequence-based fungal identification protocols.

To understand the phylogenomics, pathogenic/virulence-associated genes and genomic evolution of pathogenic species. We performed comparative genome analysis of species using tools and in-house scripts. We predicted genes and repeats, compared genomes based on synteny, identified orthologous clusters, assessed genes family expansion/contraction, predicted secretory proteins and finally searched for similar sequences from various databases.

We report here a case of disseminated Emergomyces pasteurianus infection from India in a patient with AIDS. The patient presented with weight loss, dyspnoea and multiple non-tender skin lesions over face, neck and chest over 3 months. The case was diagnosed by microscopy, histopathology of sample and isolation of fungus from skin lesion, breast nodule, bone marrow and sputum.

Apophysomyces elegans species complex is an important cause of cutaneous mucormycosis in India. However, majority of those cases are reported as case reports only. We desired to analyze our patients with Apophysomyces infection reported over 25 years (1992-2017) to understand the epidemiology, management, and outcome of the disease.

Mucormycosis is an angio-invasive infection, predominantly acquired by inhalation of sporangiospores from the environment. However, the burden of Mucormycetes sporangiospores in the air is not well studied. We aimed to estimate the burden of Mucormycetes spores in the outdoor and indoor (hospital) environment across different seasons in north India.

Mucormycosis is an angio-invasive fungal infection, associated with high morbidity and mortality. A change in the epidemiology of mucormycosis has been observed in recent years with the rise in incidence, new causative agents and susceptible population. The rise has been perceived globally, but it is very high in the Asian continent.

Mucormycosis due to Mucorales is reported at large numbers in uncontrolled diabetics across India, but systematic multicenter epidemiological study has not been published yet. The present prospective study was conducted at four major tertiary care centers of India (two in north and two in south India) during 2013-2015 to compare the epidemiology, treatment strategies and outcome of mucormycosis between the two regions. Molecular techniques were employed to confirm the identity of the isolates or to identify the agent in biopsy samples.
