Microorganism

Introduction Anti-infective agents are classified as antiseptics and disinfectants. They kills or restrict the growth of micro-organism when applied to a living tissue or inanimate objects. An antiseptic when applied to a living tissue like skin it acts as a chemical compound that kills or inhibits the growth of micro-organisms. And the disinfectant is a chemical compound which prevents infection by the destruction of harmful micro-organisms. They reacts when they applied on an inert object…

After the discovery of antibiotics in the early to middle 1900s, many people, including scientists, marveled at the thought of eradicating diseases that tortured human life for centuries. Recently, however, the widespread and inappropriate use of antibiotics has led to antibiotic resistance all over the world, becoming a very serious problem in the treating of diseases. Antibiotic resistance occurs over time when bacteria become resistant to antibiotics because the bacteria strains adapt…

Naturally, our bodies contain both bad and good bacteria. The good bacteria (probiotics) are responsible for our gut health. Candida is an example of bad bacteria, which when it surpasses the required level, it produces toxins causing diseases and infections. Ingestion of probiotics kill candida by changing the PH level that reduces its survival, preventing over multiplication of bad bacteria in the body. How then do you use probiotics to kill Candida? Constant production of toxins from candida…

Bacteria! They're everywhere, and they are usually harmful. But did you know that some bacteria are actually good for you?.. Good bacteria, called Probiotics, are friendly to the human body, and actually are very important to have inside of us. While many of us have heard of probiotics some people are still unsure or even confused as to exactly what they are and what they do. I have been asked number of times to provide some clarity on this subject. The following is a Q & A of the most common…

Parasites is an animal or plant that lives in or on a host which is another animal or plant as it obtains nourishment from the host without benefiting or killing the host. Parasites may be characterized as ectoparasites, including ticks, fleas, leeches, and lice which live on the body surface of the host and do not themselves commonly cause disease in the host or endoparasites, which may be either intercellular (inhabiting spaces in the host’s body) or intracellular (inhabiting cells in the…

3. I chose the plate with dilution factor 10-7 to count. This was the only plate that yielded an appropriate CFU, therefore, it was the sample with the highest countable colonies. The plate with the dilution of 10-6 yielded Too Many To Count (>300) while the plates with dilution 10-8 and 10-9 yielded Too Few To Count (<30). 4.If I were to do a total count on this sample, as opposed to a viable count, the total count would be higher because it accounts for all cells, not just visible and…

The whitefly Bemisia tabaci is a destructive worldwide insect that has profoundly impacted agriculture in Arizona and California. It is a highly polyphagous species that is capable of feeding on hundreds of plant species. The diversity of crops grown year-round in the Southwest creates an ideal environment for B. tabaci to flourish, often resulting in damaging infestation of melons, cotton, and broccoli. B. tabaci also transmits plant viruses such as Cucurbit Yellows Stunting Disorder Virus, or…

The lifesaving drug do not work as well as they once did”. Our body gets used to it and the surviving bacteria evolve and pass down their genes generation to generation. “treating common infections becomes more difficult”. Right now the season is winter, and this is when we are most prone to biotic infections. Antibiotics “can cause more harm than good”. It risks us getting antibiotic-resistant in the future. In an article “pencrtration of brain abscess by systemically administered antibiotics”…

The Emergence of the Antibiotic Age The origination of the first antibiotic, known as penicillin, was initially discovered accidentally by a sagacious, submissive bacteriologist who is now known primarily for this monumental breakthrough; his name is Alexander Fleming. Before this discovery was made, the risks of obtaining bacterial infections were substantially immense and unpreventable. Every doctor was helpless since there was ultimately nothing that they could do to prevent the infection…

Stacy Zemlicka Rasmussen College Author Note This research is being submitted Aug 2, 2015, Sallie Vance’ Surgical Pharmacology I believe in using antibiotics because they are strong medicines that are used to treat infections, including life threatening diseases. The antibiotics can help treat so many bacterial diseases such as viruses caused by colds, like the flu and most coughs and sore throats, ear aches or cancer issues. But not all antibiotics work against all…
