Nematode

During my freshman year of high school I earned the opportunity to conduct Intermediate Science Research through a three-year college level course provided by the University of Albany, State University of New York. The program entailed that each student find an area to research that pertained to his/her interest. In order to find an area that would encapsulate my interests, I delved into about 70 scientific journal articles, each correlating to impairments of the central nervous system.…

Trichinellosis is a parasitic disease caused by Trichinella spp., a species of intestinal nematodes that reside as encysted larvae in muscle tissue and are released upon human digestion of infected raw or undercooked meat (Gottstein and others 2009). Domestic pigs are the primary source of infection for this pathogen making uncooked pork products, such as raw-fermented sausages, at risk for containing Trichinella spp. (Gottstein and others 2009). The symptoms of this disease include: facial…

1.1 Caenorhabditis elegans (C. elegans) Caenorhabditis elegans is a free-living non-parasitic, non-infectious, non-pathogenic, transparent Nematode (roundworm). It has a full grown length of about 1mm, a life span of around 3 weeks and is found in temperate soil environments where it survives by feeding on microbes such as bacteria. [1] Consisting of about 1000 somatic cells as an adult, C. elegans is amenable to genetic crosses and produces a large number of progeny, at times even…

Nitrogen-fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gases from the atmosphere into solid nitrogen compounds that plants can use in the soil. Let's break this concept down. Nitrogen is commonly found as an inert, or nonreactive, gas in the Earth's atmosphere. In fact, 78% of the Earth's atmosphere is nitrogen in its gaseous design. This element is so sufficient that it has been incorporated into all living things on Earth. In order for this to…

INTRODUCTION Bananas are one of the most important food crops in most of the African countries. About 75% of the farmers grow the crop on 1.3million hectares in Africa. Most of this production is for local consumption. They are amongst the most important commercial subtropical fruits grown in South Africa and are planted for sale in local markets or self-consumption and only a fraction of all bananas are sold in the world markets. The production technologies used for small scale and commercial…

commonly in young children” (Suh & Keystone, 2015). Being that young children are the most commonly exposed and infected, pinworms become easily transmitted largely due to the fact of knowledge deficit in regards to transmission and prevention. The nematode can be easily spread in daycare centers, camps, schools or anytime children are in close contact. “Up to a quarter of all children worldwide are estimated to be infected with pinworm” (Diemert, 2016). In the instance of children with…

relatives or the people around us. Helminths is a parasitic worm, which when mature can be seen with the naked eye. Pregnant younger are the ones to most likely be affected by helminths. The types of helminths are tapeworms (cestodes), roundworms (nematodes) and hookworm. These worms can only survive in certain types of weather…

Introduction Parasitic helminth infections are an important burden to global public health, causing great morbidity in humans and livestock. Estimates claim that up to a quarter of the world´s population is affected by soil-transmitted helminths (1), although the incidences are mainly restricted to developing countries, due to poor sanitation resources and health care. Considering these facilities are relatively modern, it is likely that until the 19th century all human beings were infected…

Title: Which Antibiotics Kill the Most Bacteria? Caroline Gorman April 2, 2016 HB bl. 6 Purpose: The purpose of this lab was to determine which of five common antibiotics would kill the Rhodococcus rhodochrous bacteria. Hypothesis: Out of the five tested antibiotics, doxycycline will kill the most Rhodococcus rhodochrous because it is generally used to treat mild infections. This will be tested by spreading the bacteria on agar in a Petri dish and adding a small amount of each antibiotic…

The Animal Book Chapter 1: Animal characteristics Chapter 2: Body Parts Body plans refer to similarities in development, structure, and function among members of a particular group (phylum). At some point, members of that group share the same body plan during their development process. Which could be a possible explanation for shared structural plans that have been observed in the anatomy and embryology. Timing, pattern, and scale of development determine the organism's shape, and closely…
