What kinds of clinical specimens may yield a mixed flora in bacterial cultures? Oral, Skin, or GI specimens 5. When more than one colony type appears in pure culture, what are the most likely sources of extraneous contamination? Individual colonies can be picked up on the inoculating loop, or straight wire and inoculated in to the fresh agar or brother media References Cowan, M. K. (2012).

Narges GulMohammad Mrs. Loughney AP Biology 2/20/14 Chapter 18 1. Picture Structure and size of virus | Structure and size of bacteria | DNA or RNA enclosed inside a coat of protein; larger (1000 nm) | DNA and RNA floating freely in cytoplasm. Has cell wall and cell membrane; smaller (20-40 nm) | 2. 3. Three stages of viral disease emergence leading to successful host switching can be identified: (i) initial single infection of a new host with no onward transmission (spillovers into “dead-end” hosts), (ii) spillovers that go on to cause local chains of transmission in the new host population before epidemic fade-out (outbreaks), and (iii) epidemic or sustained endemic host-to-host disease transmission in the new host
Genevieve 171L Honors 11/6/08 Characteristics of the Aldox Gene Introduction This experiment was conducted by using aldehyde oxidase (AO) to genetically characterize the aldox gene. It was hypothesized that the aldox gene is recessive and sex linked. Fruit flies (Drosophilia melanogaster) are genetically well known eukaryotic organisms that were used to investigate the inheritance of the aldox gene. To determine if AO is present, an enzyme spot test was used. The yellow color indicated that AO was present and active while blue color indicated AO is not present.

MEASLES SZT TASK 3 REBEKAH HIGHTOWER A. Measles Measles, what is it? Measles is one of the most highly contagious viral diseases and sadly it can be a fatal disease. This disease took the life of 164,000 children worldwide in 2008(Measles, 2014). It is caused by an infection called the rubeola virus.
Ehrlichiosis Waukesha County Technical College Ehrlichiosis Ehrlichiosis is a bacterial disease caused by a tick bite. It can infect humans and animals and lives in the white blood cells of its host. This paper will be about the pathogens/virulence factors, pathogenesis, signs and symptoms, diagnosis, treatment, prevention, and epidemiology of ehrlichiosis. To start with, the pathogens of ehrlichiosis are three different types of bacterial species: Ehrlichia chaffeensis, Ehrlichia ewingii, and Ehrlichia muris-like (Centers for Disease Control and Prevention, 2011). The family the bacteria belong to is called Rickettsiae.
Lynn Margulis: She is best known for her theory on the origin of eukaryotic organelles and her contributions to the endosymbiotic theory. Francesco Redi: Improved the study of spontaneous generation. John Needham: Improved the study of spontaneous generation. Lazzaro Spallanzani: Made important contributions to the experimental study of bodily functions, animal reproduction, and discovered echolocation. Louis Pasteur: Remembered for his breakthroughs in the causes and preventions of diseases.
The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1348 and 1350. Although there were several competing theories as to the etiology of the Black Death, recent analysis of DNA from victims in northern and southern Europe indicates that the pathogen responsible was the Yersinia pestis bacterium, which causes the Bubonic plague, although these were different, previously unknown ancestral variants of those identified in the 20th century. The Black Death is thought to have started in China or central Asia, before spreading west. It is estimated to have killed 25 million people or 30% of the population of China. The plague then travelled along the Silk Road and reached the Crimea by 1346.
