The book The Hot Zone, authored by Richard Preston and published in New York in 1994, runs for 422 pages. In my opinion, I would rate it a six due to its inconsistent storyline that did contain some captivating scenes which left me glued to the pages and with a nauseating feeling; however, it did […]

Though there are well over seventy thousand true fungal species that inhabit this planet, very few of these cause diseases in humans, called mycoses. Many more fungal diseases are associated with various plants and other animals. Mycoses in humans can range from superficial infections to deep-seated systemic infections that are life threatening. The superficial mycoses […]

The aim of this investigation is to find out what effect out of two antibiotics, penicillin and streptomycin has on the growth and multiplication of two different species of bacteria. The two different types of bacteria we will be using are E-coli and micrococcus luteus. The Apparatus:* Four sterilised Agar plates,* Glass spreader,* Masking tape,* […]

Being part of the Sports Medicine profession, Athletic Trainers have to be ready for anything and everything when it comes to treating their athletes. This includes recognition, evaluation, education and prevention of various problems. One specific aspect of this is having a basic knowledge of contagious diseases that is seen all too commonly in Athletics. […]

In 1937, the West Nile (WN) virus was initially discovered in the peripheral blood of a woman from the West Nile province in Uganda, which is situated in Central Africa. WN viruses have been reported in various regions across the globe since their initial discovery. These reports include North Africa (Egypt, Israel), East, Central, and […]

Shigallosis is a type of infectious disease caused by a group of bacteria that primarily affect humans and primates. It is the third most common form of food poisoning in the US, following Salmonella and E.coli. Globally, approximately 165 million people are affected by Shigallosis annually, with 250,000 reported cases worldwide and about 45,000 reported […]

This reference taken in making this project has been declared […]

This report discusses what Hand, Foot and Mouth Disease (HFMD) is, how it is spread as well as the precautions one should take to avoid getting HFMD. There have been recurrent outbreaks of HFMD over the last few years and similar outbreaks of HFMD have also occurred in the region, namely in Brunei and Sarawak. […]

Protists are known to be the very first eukaryotic organisms on earth. The Kingdom Protista was first classified by Haeckel in the year 1866. Now, there are many known species of protists. After learning about protists in class, the group decided to observe the different species of protists found in pond water. The group prepared […]

The research paper investigates Bacterial Vaginosis, which is when the normal bacteria in the vagina grow excessively and cause excessive vaginal discharge. Originally known as Gardnerella vaginitis because of the bacteria believed to be responsible, it was later renamed Bacterial Vaginosis to recognize that different bacterial species naturally exist in the vaginal area and can […]

Pelvic Inflammatory Disease (PID) is a bacterial infection that affects the upper female genital tract, which includes the uterus, fallopian tubes, and ovaries. This condition often occurs when sexually transmitted infections are not adequately treated. PID can lead to complications such as scarring of the fallopian tubes, increasing the likelihood of ectopic pregnancy or infertility. […]

Both clinical and research applications often need to determine the quantity of microbes. This determination is crucial for assessing antibiotic effectiveness, therapy in clinical settings, as well as the efficiency of antimicrobial chemicals and radiation in research settings. The viable count method is commonly employed to quantify bacteria, specifically counting only living and reproducing microbes. […]

A. Define the following: Enriched Media: An enrichment medium contains some important growth factor (vitamin, amino acid, blood component, or carbon source) necessary for the growth of fastidious organisms. Selective Media: Selective media allow for the selection of particular microorganisms that may be present in a mixed culture. Selective media usually contain a component that […]

Probiotics are live microorganisms thought to be beneficial to the host organism. According to the currently adopted definition by FAO/WHO, probiotics are: “Live microorganisms which when administered in adequate amounts confer a health benefit on the host”. Lactic acid bacteria (LAB) and bifidobacteria are the most common types of microbes used as probiotics; but certain […]

The mother explains to the child that they will receive medicine, which is usually antibiotics. However, the child’s illness is probably caused by a viral infection like a cold or flu rather than a bacterial infection. Antibiotics are meant for bacterial infections such as strep throat, pneumonia, whooping cough, and acne. Misusing and overusing antibiotics […]

The care of Urinary Tract Infection (UTI) is a common costly problem in acute care and home care population. Many therapies have been made for the treatment. Despite this, the patient still suffer from pains when urinating and the financial burden. In the locality, Urinary Tract Infection was commonly experienced among teenagers due to lifestyle […]

Anti-infective agents are drugs that are designed to act selectively on foreign organisms that have invaded and infected the body of a human host. Ideally, these drugs would be toxic to the infecting organisms only and would have no effect on the host (or human) cells. Overview •Antimicrobial therapy (often termed “antibiotic therapy”) is the […]

Blood group O (or blood group zero in some countries) individuals do not have either A or B antigens on the surface of their RBCs, but their blood serum contains IgM anti-A and anti-B antibodies against the A and B blood group antigens. Therefore, a group O individual can receive blood only from a group […]

Microbiology, which involves the study of microorganisms that cannot be seen with the naked eye, encompasses various techniques such as aseptic technique, pure culture technique, and microscopic observation. Microbiologists isolate specific microorganisms from wild populations to examine them. Initially centered on harmful microorganisms leading to disease or spoilage, microbiology now acknowledges the significant roles of […]

The development of dyes to stain microorganisms was a significant advance in microbiology. Stains serve purposes such as it differentiate microorganisms from their surrounding environment and it allows detailed observation of microbial structures at high magnification. (http://insist. Back. Wise. Deed/, 0 2006-2013 Microbiology Laboratories) Sexagenarians (2005) defined staining as the method of artificially producing color […]

This chapter examines the materials and procedures utilized to collect essential information and data for the study. The bacterial isolates (Staphylococcus erasures, Escherichia coli, and Streptococcus) used in the experiment were obtained from the Institute of Biological Science, University of the Philippines Los Banos, Laguna. The bacterial isolates were subcultured on slants of Nutrient Agar […]
