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 […]

Identifying the Steps of the Scientific Method Directions: Read the following statements & match the statement letter(s) to the questions below. Some questions will have more than one answer. Statements: A scientist wants to find out why ocean water freezes at a lower temperature than fresh water. The scientist goes to the library and reads […]

Microbiology is the study of microorganisms or microbes, which are tiny life forms that cannot be seen without magnification. These microorganisms are found everywhere and have a significant impact on the planet. The discovery made by Englishman Robert Hooke in 1665 of “little boxes” or “cells” in a slice of cork through the microscope is […]

Lloyd, Jacqueline et al., Social contextual factors associated with entry into opiate agonist treatment among injection drug users. It’s a Health publication. The primary audience of the Journal is the American public. Injection drug users or the IDUs are the second largest group that has a high risk of contracting HIV infection in the United […]

The increase in water inside the cell causes the cell to become engorged and erupt. In a hypertonic environment, water will leave the cell, as the amount of water in the cell is higher than that outside of the cell. As a cell looses water in a hypertonic environment it becomes smaller in size and […]

Food microbiology involves the study of microorganisms scientifically in food production and in food itself. All the microorganisms that lead to spoilage and contamination of food are discussed in food microbiology. These microorganisms affect food both negatively and positively. They are beneficial in that they help in production of food, for instance there are microorganisms […]

Cancer is one of the diseases which have greatly affected individuals globally. Despite that, it is true that there should be a way of keeping track of the HPV virus. Regardless of that, it is clear that this virus disappears with time on its own and it doesn’t cause widespread health problems. But in case […]

The Golden era of the study of microbiology depicts the period between the 18th C and 19th C that experienced major breakthrough in scientific discoveries of especially in the field of microbiology that took place during the Renaissance era in the Europe continent. The Renaissance period greatly remembered as a period of scientific inventions, significant […]

Introduction The focus of this discussion is the question of whether we are making the world too clean. We will explore the hygiene hypothesis, which suggests that people nowadays grow up in a cleaner and more germ-free environment. As a result, when they come into contact with a different environment, health problems arise more quickly. […]

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases – enzymes which break down agarose into oligosaccharides. This physiological class branches through genii, regardless of Gram Stain status or […]
