This document discusses mold, including what it is, the conditions needed for its growth, types of mold, and health effects. It notes that mold is a microscopic organism that spreads by spores and breaks down cellulose matter. For mold to grow, it needs moisture, nutrients, and temperatures between 68-86°F. Common sources of moisture in homes include leaks, flooding, condensation, and overwatered plants. Nutrients come from materials like paper, wood, and fabrics. The document outlines types of mold like allergic, pathogenic, and toxic black mold and lists visual signs of mold growth. It identifies those at increased risk, like children and those with respiratory issues, and prevention and removal as ways to address mold
• Actinomyces species are classified as anaerobic, gram positive and filamentous bacteria.
• It is a chronic granulomatous suppurative and fibrosing disease caused by anaerobic or microaerophilic gram-positive nonacid fast, branched filamentous bacteria.
• Most of the species isolated from actinomycotic lesions have been identified as A. israelii, A. viscosus, A. odontolyticus, A.naeslundii or A. meyeri.
• These microorganisms have been identified in dental plaque, dental calculus, necrotic pulp, and tonsils.
• The usual pattern of this disease is one characterized chiefly by the formation of abscesses that tend to drain by the formation of sinus tracts.
• pus from the abscesses is examined on a clean glass slide, it shows the typical ‘sulfur granules’ or colonies of organisms, which appear in the suppurative material as tiny, yellow grains.
• Another infection that produces this type of sulfur granules is botryomycosis.
Mycology is a small topic in microbiology where questions appears less in pg entrance but still we need to know it and learn about it in safe side... so here is a ppt with detailed explanation and images

This is a presentation on Dengue and prevention methods by the Directorate of Public Health and Preventive Medicine, Government of Tamilnadu. Since the vector which transmits Dengue virus breeds in clean water collections in domestic and peridomestic areas, a concerted action with community involvement is of paramaount importance in control of Dengue. Understanding the life cycle of this vector, Aedes aegypti is the key to control of Dengue. This presentation depicts the sources of these dangerous mosquitoes which are pervaded among us. Identification of larvae in household water storage containers and destroying them is easier than adult control measures. This is an attempt to throw light on such breeding sources and how to prevent such breeding sources, thereby preventing Dengue infection.
Medically Important Candida albicans.pptxNawangSherpa6
The Presentation here is about Medically important Candida species. How does it infect the Human host? What are it's clinical manifestations and How can we diagnose for their infection and potential application for other studies.
