Introduction

Climate change is a major environmental problem, causing concern to various corners of our ecosystem. It is a result of global warming, environmental pollution and inefficient use of our natural resources. Climate change has affected almost all living organisms, including plants, animals, microorganisms and undoubtedly, man. It poses a serious threat to our ecosystem and is listed as a major concern in the Grand Challenges of the U.N. for Millennium Development and Millennium Ecosystem Assessment (Garrett 490). A wide variety of its implications, have made climate change, an important topic for researchers. There has been more awareness among researchers ...

EPIDEMIOLOGY OF COCCIDIOIDOMYCOSIS

EPIDEMIOLOGY OF COCCIDIOIDOMYCOSIS

Background: Clinical Description

The disease causing agent, Coccioides spp., causes a wide range of illness, but these illness are mostly determined by the hosts' defenses, inoculum size and possibly specific organism virulence. Most of the clinical infections (about 60%) show few or no respiratory symptoms. However, the rest 40% may show symptoms of illness that may either be acute or sub-acute. The illness could range from progressive pneumonia to flu-like conditions. Misdiagnosis usually occurs in self-limited community-acquired pneumonia. According to Saubolle, McKeller & Sussland (2007), only 29% of 56 people who had community-acquired pneumonia were diagnosed of coccidioidomycosis. The exact ...

1. A fever of unknown origin (FUO) in a patient with leukemia leads itself to a wide range of differential diagnoses. Traditionally FUO is divided into four categories: classic, nosocomial, neutropenic, and HIV-associated. Classic FUO can be a result of infections, malignancy, or collagen vascular disease. Nosocomial FUO is most likely due to C. difficle infections, pulmonary embolism, or an infected catheter. Neutropenic FUO can be caused by opportunistic bacterial or fungal infection. Lastly, HIV FUO can be due to M. avium-intracellulare complex or P. carinii. Most likely because of the patient’s WBC count and history of leukemia, ...

Mucor

Mucor is a type of fungal infection that caused by mold which is commonly found in plants, decaying fruits and vegetables, soil, manure and toxin of stored food. Mucor mainly effects the immunity compromised individuals and effects sinuses and lungs as it is usually inhaled during the breathing process. Fungus incorporates about 50 species some of them are prone to high temperatures and hence, they can cause infections mainly known as zygomycosis or mucormycosis. According to CDC (2015), mucormycosis effects the immunity comprised people at a higher pace and due to its contact with human body via inhalation, cut, ...

The number of people on the planet continues to increase and with them, the need for more and more nutritious food grows. For that reason, scientists seek research to genetically change plants and animals to provide medicine, good, and organisms not for consumption. As the public is exposed to information on genetically modified organisms (GMOs), strong opinions are forged concerning the safety of eating them. Questions arise over the risks presented to human beings and the environment, if GMOs are really necessary to supply the world with adequate amounts of food, if there are alternatives, and what surrounding ethical ...

Introduction

Polymerase Chain Reaction (PCR) is a very influential technique that helps in amplifying the specific segments of DNA. This biochemical procedure is performed in-vitro that is quite different from cloning. This technique is a fusion of synthesis protocol of distinct repeated segments of DNA and thermostable DNA polymerase application that has given scientists a very potent analytical, immunological and molecular technique used prevalently in clinical laboratory science (Garibyan & Avashia, 2013). PCR is based on three primary steps that include denaturation of the template into single strands, annealing ...

This refers to moulds of a particularly microbial genus commonly found in the digestive system, decaying vegetable matter, plant surfaces, and soil. Depending on the route of infection, mucor can result in two types of infection (Ibrahim, Spellberg, Walsh, & Kontoyiannis, 2012). In the case of pulmonary exposure, the victim inhales fungal spores found in the environment which may cause an infection to develop in the sinuses, face, eyes and lungs. During cutaneous exposure, the fungus enters the skin via puncture wounds, cuts, or scrapes. Mucormycosis, though rare is an infection attributed to the organisms belonging to a group of ...

1. Spherule Spherule is the smaller spherical structure that lives inside the host. Such as, in the case Coccidioides immitis when it enters the host the fungal hyphae breaks into smaller spores and develop into spherules which release endospores through rupturing inside the host. 2. Pyogranulomatous Pyogranuloma is an inflammatory process that involves polymorphonuclear cell infiltration in the affected area of inflammation which can be manifested by the presence of macrophages, mononuclear cells, and lymphocytes. Such as Histoplasma capsulatum infections may result in Pyogranulomatous reactions inside dermal and subcutaneous tissues. 3. Differential Diagnosis Differential diagnosis is a medical term ...

Introducing the Microorganism

Candida albicans is a human microbiome member. It is opportunistic in nature and exists as a non- harmful resident of the genitourinary tract in 70% and of oral cavity in 75% of humans. It has shown opportunistic behaviour leading to infections in case of individuals whose immune system is compromised (immunocompromised). C. albicans is mainly responsible for 2 types of infection: superficial candidiasis like vulvovaginal or oral infections and systemic life-threatening infections. C. albicans has been observed to cause vulvovaginal candidiasis in approximately 75% of women. C. albicans is an obligate and diploid organism possessing 8 pairs of chromosomes, ...

Abstract

The experiment was performed to analyze the outcomes of temperature on the ability of fungal and bacterial amylase to breakdown starch to maltose. Therefore, the study will reveal the optimal temperature for amylase activity. The initial steps include preparing the materials and tools used during the experiment. A timetable for comparing temperature and function was generated. Test tubes and plates were properly labeled. Iodine was needed for every spot plate so that the fungal amylase, bacterial amylase, fungal amylase and the starch solution can be added to the iodine in a time and temperature dependent fashion. Observing ...

Skin Biopsy

More often than not, a skin sample may appear to be abnormal with regards to the fact that the skin has changed color, shape, or appearance. The change in skin color, shape, or general appearance can be due to skin cancer, fungal infection, psoriasis or any other infection of the skin. To confirm the actual cause of such abnormality on the skin, dermatologists usually recommend a skin biopsy, which involves the removal of part of the skin for use in the histological examination or any other relevant tests. The word biopsy is derived from Greek words ‘bios’ meaning ‘life’ and ‘ ...
