This investigation is looking at three water samples A, B, and C, which have been associated with a gastrointestinal infection of children in a small village. In which three walls have been associated with the path of infection. The likely cause of outbreak has been identified by using a serial dilution of the samples, which […]

Hypothesis: If the most effective solution for pathogenic bacteria is household bleach, then the descending order from best to least are household bleach, Penicillin, Monoclinic, Household Disinfectant, Anti- Bacterial Soap, Erythrocyte, Sterile Filter Paper. Materials: The materials used in this lab include a agar, a Petri dish, test tubes containing the pathogenic bacteria: Staphylococcus erasures, […]

Natural cleaning, Healthy living Air, water, residual agricultural chemicals (pesticides/herbicides) and unpleasant odours (food, bathroom, refrigerator, cigarette smoke and turbid indoor air odours all contribute to our daily toxic load. Most of the solutions developed by industry for ridding ourselves of these pollutants contain additional chemicals, which increase our exposure to potentially harmful chemicals. How […]

Abstraction The subject of this research involved the happening of familial transmutation in bacteriums ( E. Coli ) . More specifically, antecedently prepared pGLO plasmid–which consisted of the cistron to be cloned–was used to transform non-pathogenic bacteriums. The pGLO plasmid contained a cistron for the Green Fluorescent Protein ( GFP ) from a bioluminescent Portuguese man-of-war […]

Extensive investigation was carried out on rheumatic fever during the early 1900s due to its high prevalence in children worldwide, leading to numerous hospitalizations. While developed nations have seen a decrease in rheumatic disease prevalence since the late 1900s, non-developed countries still struggle with significant issues related to rheumatic fever, which are now even more […]

In today’s world, the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment. It has been seen that helpful bacteria are useful in dissolving organic sludge from water, breaking down the growth of algae, reducing the various noxious odours […]

Immunization is the act of administering modified or inactivated microorganisms, such as viruses and bacteria, to enhance immunity against specific illnesses. This process stimulates the immune system to develop a defense mechanism against diseases rather than causing them. Consequently, when vaccinated individuals come into contact with disease-causing pathogens in the future, their immune system will […]

The development of recombinant DNA technology is, in biological terms a very recent discovery. It was founded in 1973 by Cohen and Boyer, the first two scientists to successfully transplant a section of DNA from one bacterium and insert it into another using restriction enzymes, creating the first transgenic organism1. As with every biological discovery […]

A ruminant is an herbivore with a multichambered stomach. The example of a ruminant that will be used is cattle. The example of the carnivore that will be used is a dog. The carnivore is a meat eating organism. The dog is a carnivore, and wild members such as wolves are predators. Refer to fig. […]

Microbe is a term for tiny organisms that individually are too small to be seen with the unaided eye. There are five main types of microbe: bacteria, archaea, fungi, protists and viruses. * Bacteria – Bacteria are not only are with us all the time, but help us do an amazing array of useful things […]

Experiencing “life on the edge”, bacteria have to respond to changes in the environment in order to survive. Facing limited resources and coupled with intense competition in almost every environment, bacteria have to accommodate any potential energy sources of nitrogen, carbon while resisting toxicity to their regulatory process and metabolism. By establishing an intra and […]

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,* […]

A species is a group of organisms that have the capacity to interbreed, leading to the production of offspring that are both fertile and viable. Bulldogs, terriers, and golden retrievers, despite their different physical characteristics, are all classified as dogs because they can interbreed. Both humans and cats can interbreed within their species, but not […]

A batch of our citizens are dependent on commercially available antifungals to command fungi growing at places and concerns. However. most of these merchandises are dearly-won and contain unsafe chemicals that may harm human wellness and other beings. The purpose of this investigatory undertaking is to fabricate an autochthonal merchandise that is effectual. innocuous. and […]

Cockroaches are scavengers that can be found anywhere and pose a health risk. They can carry bacteria on their legs from spoiled food and transfer it to other food items. While they do not directly transmit diseases, disease-causing organisms can multiply in their bodies and contaminate utensils and plates when they defecate. For instance, cockroaches […]

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 the plant kingdom flowers are what we think the world represents. Flowers are given to people as well as most likely they are roses, tulips and any other beautiful flowers we can think of. In the Philippines there is a flower that’s not so attractive but it makes up for the uses and the […]

Defention: One of the most debilitating side effects of radiotherapy and chemotherapy treatment. It is characterized by both inflammation and cell loss in the epithelial barrier. Mucositis is a very complex condition: it develops as a series of dynamic interactions that begin in the epithelium but in a later stage involves other tissue mucosal components […]

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 […]

Micro-organisms Micro-organisms (or microbes) are literally microscopic organisms, which can only be seen properly with the aid of a microscope. These include bacteria, microscopic fungi (moulds) and protoctists. Although viruses, which are even smaller than bacteria, are generally considered to be non- living entities, they might also be included here as they are important disease-causing […]

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 […]

This report discusses an experiment that was done to demonstrate the effects of lysozyme on populations of Gram positive and Gram negative bacteria. Bacteria have a cell wall composed of peptidoglycan that gives the wall its strength. Gram negative bacteria have and extra component of lipopolysaccharide (LPS), that is stabilized with magnesium ions, to their […]
