Coliform bacteria

Today in class we used GloGerm to see how well we wash our hands. Since school just started many people are getting sick including me. Washing our hands is a very important during the flu season and every day. Illnesses are spread when particles from a cough or sneeze gets in the mouth or nose of a nearby person. This includes doorknobs, desks, tables, phones, pencils, basically anything you touch and someone else touches. It is key to not touch your eyes, mouth, or nose especially during the…

 Baby teeth start to shed from the age of 6-7 years.  Children have 20 teeth. They don’t have premolar teeth.  Adults have 32 teeth.  Some adults have extra teeth called Mesiodense and paramolars, that are very rare.  Teeth formation starts even before you are born - milk teeth or baby teeth start to form within the gums when the baby is in the womb, but they come through when the child is between 6-12 months old.  Humans use four different kinds of teeth (incisors, canines, premolars and…

Varroa destructor (Anderson and Trueman, 2000) is an obligatory ectoparasite of the honeybee (Apis mellifera L). It caused severe damage to populations of this species world-wide in recent years (Le Conte et al., 2010). The direct negative effect of the Varroa on honeybee has well documented (Weinberg and Madel, 1985; Daly et al., 1988, Wienands and Madel, 1988; Marcangeli et al., 1992; Bowen-Walker and Gunn, 2001; Contzen et al., 2004; Yang and Cox-Foster, 2005; Belaïd and Doumandji, 2010;…

The common cold is a common viral infection of the nose and throat. It has more than 3 million US cases per year. It spreads easily, is self-treatable, is self-diagnosable, lab tests and imaging are not required, and is short term, so it almost always goes away within days to weeks. Although more than 100 viruses can cause a common cold, there are two main ones. They are the Rhinovirus, which is most active in early fall, spring, and summer. It causes 10-40% of colds. The second one is the…

Methicillin- Resistant Staphylococcus aureus infection, also known as the “Super Bug,” is a very deadly, and hard to cure staph infection caused by the Methicillin-Resistant Staphylococcus aureus bacterium. MRSA is a staph bacterium that is harmless unless it gets into our bodies or into open wounds. The MRSA bacterium was discovered in 1961 by a few British Scientists. The infection at first, was not very harmful since it was easily treated, but as time has passed, the bacterium has become…

Research by Philip Tierno, Jr., Ph.D., microbiologist, immunologist, and author of The Secret Life of Germs, has conducted research which indicates that your carpet and rugs are a lot dirtier than you think. In fact, these areas have around 200,000 bacteria per square inch. Eew, that's about 4,000 times dirtier than your toilet. How long has it been since you’ve cleaned your oriental or other area rugs? Surprisingly, they’re often overlooked. Many people are diligent about cleaning their…

may result in permanent damage like deafness or blindness. Hence these symptoms should be taken seriously and medical advice sought immediately. Meningitis is caused by infective organisms such as bacteria and viruses. Accordingly, it is classified as Bacterial or Viral Meningitis. Common bacteria causing meningitis are E Coli, Neisseria meningitides, Streptococcus pneumoniae and H influenzae. Common viruses causing meningitis are herpes virus, adeno virus, enterovirus etc. In children or…

Next, the examples used by Jerry Coyne follows Darwin’s theory of the six points of evolution, gives the scientific method to prove the origins of all living organisms, and I will explain speciation, common ancestry, and natural selection. As has been mentioned, speciation is the third point in the evolution theory, and is used to explain the vast diversity of species in the world. To resume, speciation is when one common ancestor splits into separate versions of the one common ancestor. The…

that stood out was that the news article used the statement from Dr. Timothy Lu, “There’s a symbiotic relationship between the two sides, human and bacteria” to emphasize what the point of relating gut bacteria and humans was, while the journal article just used more scientific facts and terms to talk about more specific conclusions between gut bacteria and social behavior. Obviously, the journal article was narrower in its discussion while the news article used some other outside sources also…

Louis Pasteur had multiple discoveries that affect each one of us today. We have a choice to have our children immunized, we have sterile surgical areas, and we have the process of pasteurization. My family has been blessed by all of these discoveries. My husband works in the OR doing neurophysiological monitoring of patients. He is able to see the sterile environment of the OR first hand. What was the motivation that led to the discovery? Louis Pasteur wanted to understand why some…
