Danielle Sauter-Henson Professor Davis BIOL 215-01 14 March 2017 Chlamydia Etiology Chlamydia trachomatis is among the most common bacteria transmitted within the united states. This specific type of chlamydia can cause several sexually transmitted and congenital diseases such as lymphogranuloma venereum and trachoma. They are nonmotile and their replication can only occur within vesicles of host cells. Originally, scientists believed that chlamydia was a virus because the size of it was small, and

1752. However, it is suggested that anthrax originated in Egypt in 700 BC (cdc.org). It was not until the 1800’s when Robert Koch wanted to discover what caused anthrax. Koch discovered that the specimens were rod-shaped bacteria. Bacillus anthracis is rod-shaped, Gram-positive bacteria, and has the ability to form endospores and are anaerobic (Bauman 695). Once inside the host an anthrax toxin is secreted that kills cells and another toxin creates edema (Bauman 695). There are four different ways to

candidiasis. Because of an underdeveloped immune system, infants are also at risk for developing thrush. Another cause of Pseudomembranous candidiasis is the exposure of a person to broad-spectrum antibiotics. These antibiotics eliminate other competing bacteria within the mouth, allowing candida albicans to overgrow. The characteristics of the infection can be determined by what led to its formation in the first place. Antibiotic exposure is typically responsible for an acute (rapid) expression of the condition

Bioterrorism is the use of harmful substances to seriously hurt or kill another person. Schmalleger (2013) accurately defines bioterrorism as the “intention or threaten use of viruses, bacteria, fungi, or toxins from living organisms to produce death or disease in humans, animals, or plants” (p. 591). This form destruction can easily spread to mass quantities of people in a timely fashion making it a great concern among our law enforcement and other agencies. There are many forms of bioterrorism

Intro Pathogens in drinking water may contain disease-causing organisms, or pathogens. Pathogens include various types of bacteria, viruses, protozoan parasites, and other organisms (EPA). Contamination of drinking-water by microbial pathogens can cause disease outbreaks and contribute to background rates of disease. There are many treatment options for eliminating pathogens from drinking-water. Finding the right solution for a particular supply involves choosing from a range of processes. It is

SN=Squalane, nutrient broth; NSN=No squalane, nutrient broth; SM=Squalane, minimal media; NSM=No squalane, minimal media. For each media, n=5 with squalane, n=5 no squalane. Stars and squares signify significant difference between the growth of the bacteria grown in nutrient broth, and minimal media, respectively (p<.000). Media-dependent difference in growth between samples supplemented with squalane and those that were not, as found by a Repeated Measures ANOVA, p=.052. Error bars for minimal media

The advantages of this outer membrane include protecting the bacteria from dyes and various antibiotics that would normally attach and damage the inner membrane. Although rod-shaped, when in the presence of oxygen, C. tetani changes into its endospore conformation, which closely resembles a drumstick or tennis racket (Bruggeman). In addition, C. tetani are motile bacteria and move by the use of a rotary flagellum. The flagellum are positioned in a peritrichous orientation

Sepsis is a complication caused by a serious response to infection, which can lead to multiple issues including death. Physicians have a difficult time diagnosing sepsis because it happens fast, and it can be very easily confused with other conditions that are present. According to a new vital signs report released by the CDC, 7 in 10 patients with sepsis had used healthcare services recently or had chronic diseases that required frequent medical care. These represent opportunities for healthcare

1.1 Compare the ultra structure of a prokaryotic and a eukaryotic cell. ANSWER: Prokaryotic and Eukaryotic organisms: are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane while membranes are composed of phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure. The main different between the both cell organism is nucleus: Prokaryotic cells are smaller and simpler organisms without no nucleus but most are unicellular, while eukaryotic

La importancia de lavarse bien los dientes La gingivitis es una enfermedad que daña las encías y es causada por un grupo de bichitos malos que son bacterias y los pedacitos de comida que se pegan en los dientes, a esto se le llama placa. La placa empieza a formar hoyos en los dientes y si no se quita, se forma una sustancia dura que se queda en los dientes llamada sarro. Algunas causas de las gingivitis son enfermedad en general, cepillarnos mal los dientes, los dientes chuecos, que un diente esté
