  • FINAL RISK ASSESSMENT for Aspergillus Niger (February 1997)
    ATTACHMENT I--FINAL RISK ASSESSMENT FOR Aspergillus niger (February 1997) I. INTRODUCTION Aspergillus niger is a member of the genus Aspergillus which includes a set of fungi that are generally considered asexual, although perfect forms (forms that reproduce sexually) have been found. Aspergilli are ubiquitous in nature. They are geographically widely distributed, and have been observed in a broad range of habitats because they can colonize a wide variety of substrates. A. niger is commonly found as a saprophyte growing on dead leaves, stored grain, compost piles, and other decaying vegetation. The spores are widespread, and are often associated with organic materials and soil. History of Commercial Use and Products Subject to TSCA Jurisdiction The primary uses of A. niger are for the production of enzymes and organic acids by fermentation. While the foods, for which some of the enzymes may be used in preparation, are not subject to TSCA, these enzymes may have multiple uses, many of which are not regulated except under TSCA. Fermentations to produce these enzymes may be carried out in vessels as large as 100,000 liters (Finkelstein et al., 1989). A. niger is also used to produce organic acids such as citric acid and gluconic acid. The history of safe use for A. niger comes primarily from its use in the food industry for the production of many enzymes such as a-amylase, amyloglucosidase, cellulases, lactase, invertase, pectinases, and acid proteases (Bennett, 1985a; Ward, 1989). In addition, the annual production of citric acid by fermentation is now approximately 350,000 tons, using either A.

  • Chapter One 1
    CHAPTER ONE 1. INTRODUCTION 1.1. Introduction Otomycosis is fungal infection of the external auditory canal and its associated complications sometimes involving the middle ear. It occurs because the protective lipid/acid balance of the ear is lost. Fungi cause 10% of all cases of otitis externa. In recent years, opportunistic fungal infections have gained greater importance in human medicine, perhaps because of the increasing number of immunocompromised patients. However, such fungi may also produce infection in immunocompetent hosts in immunocompromised patients; treatment of otomycosis should be vigorous to prevent complications such as hearing loss and invasive temporal bone infection. Its prevalence is greatest in hot humid and dusty areas of the tropics and subtropics. Andrall and Gaverret were the first to describe fungal infections of the ear; although a wide spectrum of fungi are involved, Aspergillus and Candida are the most common species encountered. In 1960’s studies by Geaney and by Lakshmipathi and Murthy revealed that all cases observed by them had been caused by either Aspergillus or Candida species (Satish et al., 2013). The infection usually characterized by inflammation, pruritus, trauma to external auditory canal, scaling and severe discomfort such as suppuration and pain (Desai et al., 2012). Aspergillus niger and Candida albicans are by far the most common offenders, a wide spectrum of other fungi can cause otomycosis. Various factors have been proposed as predisposing factors for otomycosis, including a humid climate, presence of cerumen, instrumentation of the ear, 1 immunocompromised host, more recently, increased use of topical antibiotic/steroid preparations (Prasad et al., 2014). Fungi are abundant in soil or sand that contains decomposing vegetable matter.

This increase is directly related to the growing population of immunocompromised Bhagwan College of Pharmacy, Aurangabad, individuals especially children resulting from changes in medical practice such as the use of intensive India chemotherapy and immunosuppressive drugs. Although healthy children have strong natural immunity against fungal infections, then also fungal infection among children are increasing very fast. Virtually not all fungi are Address for correspondence: pathogenic and their infection is opportunistic. Fungi can occur in the form of yeast, mould, and dimorph. In Dr. Akansha Jain, children fungi can cause superficial infection, i.e., on skin, nails, and hair like oral thrush, candida diaper rash, E-mail: akanshajain_2711@ yahoo.com tinea infections, etc., are various types of superficial fungal infections, subcutaneous fungal infection in tissues under the skin and lastly it causes systemic infection in deeper tissues. Most superficial and subcutaneous fungal infections are easily diagnosed and readily amenable to treatment. Opportunistic fungal infections are those that cause diseases exclusively in immunocompromised individuals, e.g., aspergillosis, zygomycosis, etc. Systemic infections can be life-threatening and are associated with high morbidity and mortality. Because diagnosis is difficult and the causative agent is often confirmed only at autopsy, the exact incidence of systemic infections is difficult to determine.

Methods: Ninety patients aged (12-72) years who presented with otomycosis at Prince Hashim Hospital in Zarka between October 2007 to June 2009 were enrolled in this study. Patients were divided into two groups, group A (48 patients): patients were treated by toileting and application of Miconazole cream, group B (42 patients): patients were treated by toileting and using Clotrimazole 1% (otozol) otic drops. Patients followed after one and two weeks. One way ANOVA test was used to calculate the significant differences at P<0.05 between the means of the study treatment groups Results: Patients in group A (Miconazole) showed a better response to treatment in comparison to patients in group B (Clotrimazole drops). Conclusion: Although the two treatment regimens showed no statistically significant difference due to the small number of cases, Micanazole cream after toileting is a better choice due to its lower cost and better compliance Key words: Clotrimazole (otozol), Miconazole, Ootomycosis, Toileting.

  • Candida Albicans Virulence Factors and Its Pathogenicity
    microorganisms Editorial Candida Albicans Virulence Factors and Its Pathogenicity Mariana Henriques * and Sónia Silva CEB-Centre of Biological Engineering, University of Minho, 4710-057 Braga, Portugal; [email protected] * Correspondence: [email protected] Candida albicans lives as commensal on the skin and mucosal surfaces of the genital, intestinal, vaginal, urinary, and oral tracts of 80% of healthy individuals. An imbalance between the host immunity and this opportunistic fungus may trigger mucosal infections followed by dissemination via the bloodstream and infection of the internal organs. Candida albicans is considered the most common opportunistic pathogenic fungus in humans and a causative agent of 60% of mucosal infections and 40% of candidemia cases [1,2]. Several virulence factors are known to be responsible for C. albicans infections, such as adherence to host and abiotic medical surfaces, biofilm formation as well as secretion of hydrolytic enzymes. Moreover, C. albicans resistance to traditional antimicrobial agents, especially azoles, is well known, especially when Candida cells are in biofilm form. This Special Issue covers different aspects related to C. albicans pathogenicity, virulence factors, the mechanisms of antifungal resistance and the molecular pathways of host interactions. The review by Ciurea et al. [3] presents the virulence factors of the most important Candida species, namely C. albicans, contributing to a better understanding of the onset of candidiasis and raising awareness of the overly complex interspecies interactions that can change the outcome of the disease. The article by Yoo et al. [4] provides a comprehensive review about the association between C. albicans and the cases of persistent or refractory root canal infections.

This host–pathogen association drives microbial evolution, as such organisms are under selective pressure and can become more pathogenic. Some of these microorganisms can quickly spread through the environment via transmission. The non-transmittable fungal pathogens, such as Cryptococcus, probably return into the environment upon decomposition of the infected host. This review analyses whether re-entry of the pathogen into the environment causes restoration of its non-pathogenic state or whether environmental factors and parameters assist them in maintaining pathogenesis. Cryptococcus (C.) neoformans is therefore used as a model organism to evaluate the impact of environmental stress factors that aid the survival and pathogenesis of C. neoformans intracellularly and extracellularly. Keywords: Cryptococcus; environmental factors; pathogenesis; survival; virulence factors; transcriptional factors; signalling factors 1. Introduction The genus Cryptococcus is defined by basidiomycetous fungi that can transform into a yeast state [1].
