Herbal extracts increase the mechanisms related to wound healing, like blood clotting, fighting infection, and epithelialization. The effect responsible for this property may be the presence of phytoconstituents like flavonoids, polyphenols, and alkaloids.

This study describes the clinical characteristics, management and outcomes of CAM cases, and factors associated with mortality.
Methods: Microbiologically confirmed CAM cases were enrolled from April 2021 to September 2021 from ten diverse geographical locations in India.
This study was aimed to investigate the association between virulence factors and antifungal susceptibility pattern among species. This study was carried out in the Department of Microbiology, from May 2018 to June 2019. A total of 52 isolates obtained from various clinical samples were speciated based on microscopic identification by lacto phenol cotton blue (LPCB) mount and slide culture technique.

The objectives were to examine the monthly trend of COVID-19 Associated Mucormycosis (CAM) cases among in-patients and to identify factors associated with development of CAM.
Methods: Eleven study sites were involved across India; archived records since 1st January 2021 till 30th September 2021 were used for trend analysis.
Background: Trichoderma spp. are filamentous fungi causing invasive fungal diseases in patients with haematological malignancies and in peritoneal dialysis patients.
Objectives: To analyse clinical presentation, predisposing factors, treatment and outcome of Trichoderma infections.
Purpose: Trichosporon species are emerging human pathogens, accounting for the second most common cause of non-candidal mycosis. Rapid and reliable identification of these agents allows a better understanding of their epidemiology and therapeutic management. The Matrix-Assisted Laser Desorption Ionization-Time-of-Flight Mass Spectrometry (MALDI-TOF MS) technique has the potential to be precise, fast and cost-effective.

All the clinical samples that grew species, identified and confirmed by polymerase chain reaction (PCR) using genus-specific primers, were considered for the study. Confirmation of the species was carried out by specific PCR.

A 60-year-old male patient undergoing chemotherapy for multiple myeloma Stage II presented to our hospital with complaints of cough, haemoptysis, fever and loose stools. Sputum sample was sent for fungal culture. Fungal culture on Sabouraud dextrose agar yielded bluish-green velvety growth with orange-to-red diffusible pigment on the reverse.

Cryptococcosis is a life-threatening infection caused by Cryptococcus neoformans and C. gattii species complex. In the present study, to understand the molecular epidemiology of 208 clinical isolates of Cryptococcus from different parts of India, multilocus sequence typing (MLST) using ISHAM MLST consensus scheme for C.

The skin infections caused by Malassezia have poor patient compliance due to its chronicity and recurrent nature of the disease. There is also a lack of standardised antifungal susceptibility profile for Malassezia due to its complex growth requirement.

Universally reported fungi are Candida, especially Candida albicans, Cryptococcus, Aspergillus, Trichophyton rubrum and Pityriasis versicolor. Here, we report a case of infection caused by a rare fungus Diaporthe.

The surfaces of devices are ideal sites of attachment for bacterial cells and an increase in biofilm formation. Biofilms have been a constant concern due to their complex extracellular matrix (ECM) resulting in multiple drug resistance.

Methods: Consecutive patients with proven or probable/putative IMIs were enrolled during the study period. Subjects were categorized into classical (neutropenia, malignancy, transplant recipients on immunosuppression) and non-classical (chronic obstructive pulmonary disease, diabetes, liver disease and glucocorticoids) risk groups.
Background: Invasive infections due to spp. have increased recently and are frequently associated with indwelling medical devices. Such infections which are associated with biofilm formation do not respond to the routinely used antifungal agents and are often persistent, associated with high mortality rate.

Trichophyton mentagrophytes is considered to be a species complex composed of several strains, which include both anthropophiles and zoophiles. Accurate discrimination is critical for comprehensive understanding of the clinical and epidemiological implications of the genetic heterogeneity of this complex.

As per literature search, there is a dearth in the study on virulence factors of dermatophytes from the Indian sub-continent and moreover the association of the virulence factors and the host tissue in vitro helps in understanding the host-pathogen interaction.
Aim: To analyse the enzymatic and non-enzymatic virulence activities of dermatophytes on solid media.
Peritonitis is an inflammation of the peritoneum that occurs in patients with end-stage renal disease (ESRD) treated by peritoneal dialysis.
