Worldwide, fungi are responsible for a significant amount of human morbidity and mortality and they tend to infect the immunocompromised and vulnerable. Antifungal drug resistance is becoming more and more evident, which has significant repercussions for infections of the skin, the intestines and the bloodstream. The challenges and repercussions of antifungal drug resistance are examined in this review, which also discusses the efficacy of wellestablished strategies for disease mitigation. To find effective solutions, it is also necessary to clarify the cellular and molecular mechanisms of fungal resistance. For sterilization and processing of medical devices, the established methods of fungal decontamination work well. However, the presence of pathogenic fungi in biofilms that refuse to break down can cause problems, especially when cleaning. Antifungal materials and appropriate disinfection and sterilization methods should be taken into account when developing new designs for implantable and reusable medical devices. Because mycotoxins are recalcitrant and difficult to eliminate once they have formed, it is recommended to use appropriate end-toend processes to prevent the growth of fungi that produce mycotoxin on food.
Eukaryotic fungi can take on the forms of yeast, mold, or dimorphic bacteria. Fungi are multicellular and have long filaments that are referred to as hyphae and grow via an apical extension, whereas yeasts reproduce by budding. Fungi are common in the air, water and soil of the natural world and they thrive in warm and humid environments. In fact, fungi are the primary decomposers in many ecosystems, releasing enzymes that break things down. Most plant life has non-pathogenic endophyte fungal species that live between the plant cells and produce alkaloid toxins that kill insects and other invertebrates and vertebrates. While some species of nycorrhizal fungi are plant pathogens that are associated with crop destruction and have an impact on food security, nycorrhizal fungi have a symbiotic relationship with plants that influences nutrient and water uptake. Fungal species pose a significant threat to public health as they are increasingly linked to mortality and morbidity. Around 13 million infections and 1.5 million deaths worldwide are attributed to fungal pathogens annually. Fungal infections, which have traditionally been associated with severe infections in immunocompromised individuals, are increasingly being linked to high mortality rates in immunocompetent individuals. The dimorphic fungi Histoplasma, Blastomyces, Coccidioides and Paracoccidioides affect immunocompetent individuals, while Cryptococcus, Candida, Aspergillus and Pneumocystis are associated with immunocompromised individuals [1,2].
As humans primary or opportunistic pathogens, the disease or mycosis that results can be superficial, like an infection of the skin, hair, nail, or mucosal surfaces, or invasive, progressive fungal infections (IFIs) that affect the internal organs. The primary risk factor for pneumocystis pneumonia in HIV patients is a defect in cell-mediated immunity that typically results in a decrease in the activity of CD4+ lymphocytes. Tissue damage must be observed through a histopathological examination in order to be categorized as an invasive fungal disease (IFD) and the causative agent must be isolated from clinical samples and cultured. The rate at which opportunistic infections are identified during intensive treatments has increased as a result of advancements in medical procedures, an increase in the number of medical surgical procedures and an increase in therapeutic treatment protocols. Patients with asthma, cirrhosis, diabetes, cystic fibrosis (CF), chronic obstructive pulmonary disease (COPD), cancer and fungal infectious diseases, such as COVID-19 and tuberculosis (TB), can also be affected by fungal infectious diseases. Co-infections with viral pathogens are especially dangerous and patients with COVID-19 are more likely to die from the fungal species Aspergillus and Mucor. Aspergillus fumigatus-caused fungal meningitis has been linked to corticosteroid parenteral injections and Sarocladium kiliensecaused fungaemia was found in oncology patients receiving IV antinausea medication. Due to their prolonged and severe neutropenia, patients with blood cancers like leukemia are more likely to develop invasive fungal diseases as a result of anticancer therapy [3].
Transplant patients, cancer patients, patients in intensive care units (ICUs) and HIV, influenza and COVID-19 patients all have high rates of morbidity and mortality. Climate change, agricultural practices, occupational hazards, forest erosion, human migration patterns, soil dispersion, patient immunosuppression, improved disease recognition and diagnostic tests are all linked to the emergence of fungal pathogens. Biofilm formation, antifungal drug tolerance and antifungal resistance all directly contribute to the rising number of fungal morbidity and mortality cases. The absence of a discernible toxic effect on the treated fungal species is antifungal resistance; Antifungal tolerance, on the other hand, is the emergence of a partial growth after 24 hours, which can be observed in susceptibility testing, even at concentrations of inhibitory drugs. Polyene, azoles, allylamines and echinocandins—the four classes of antifungal drugs are frequently encountered. Published reviews can be used to obtain the chemical structure formulas of related antifungal medications [4].
Fungal pathogens pose a significant threat to public health and biocidal resistance that incorporates AMR has increased the problem. A fungal priority pathogen list has been released by the World Health Organization (WHO), highlighting the seriousness of the disease risk posed by these potentially lethal organisms. The lack of novel antifungal therapeutic options and biocompatibility issues that go along with them contribute to antifungal resistance, which limits its medical applications. The WHO-listed pathogens C. auris and C. neoformans will continue to cause unacceptable mortality rates if effective control measures are not implemented. Additionally, new species, such as the non-ablicans Candida BSIs, will emerge, resulting in an increase in AMR and death rates, particularly among immunocompromised individuals. Preventing disease outbreaks and transmission is the most effective strategy, as is the case with all infectious diseases [5].
In hospitals, where fungal biofilm formation on in-hospital medical devices is a major concern, the implementation of efficient disinfection and sterilization procedures is crucial. Currently, there is a global drug resistance crisis and fungal AMR diagnosis and monitoring are frequently neglected. Improved fungal diagnostic and detection techniques and efficient communication with clinicians are required to more accurately monitor and respond to the underestimated number of fungal-mediated infections. Antimicrobial therapeutics should not be used in large quantities without additional research. To prevent device-related transmission, it is urgently necessary to comprehend the cellular and molecular mechanistic relationship between device reprocessing and the inactivation of biofilm-forming fungi. If there are too many cleaning and processing steps to meet the margin of safety in the healthcare setting, semi-critical devices should be reviewed to reduce the risk to the patient. Because mycotoxins are recalcitrant and difficult to eliminate once they have been formed, it is recommended that the proper end-to-end processes be carried out in order to prevent the growth of fungi that produce mycotoxin on foods. The OneHealth strategy will support and facilitate solutions to this complex societal problem.
