Giardia lamblia is a flagellated enteric protozoan parasite that is found in soil, food, and water (“Giardia lamblia” sec 1). This microorganism tends to live in the small intestines of humans. G. lamblia has two separate morphological stages. The first morphological stage is the trophozoite stage. In the trophozoite stage, this microorganism is shaped like a flattened pear. During this stage, the microbe is about ten to twelve micrometers long and about five to seven micrometers wide. Bilaterally
Giardiasis is a disease of the lower digestive system caused by the parasite Giardia lamblia which is transmitted via a faecal-oral route. The infection is acquired when a person ingests a dormant cyst of the parasite, usually by drinking contaminated water. The disease affects around 200 million people worldwide and is especially prevalent in third world countries, where there are larger populations of people in areas with poorer sanitation and therefore a greater risk of the parasite being passed
parasites involved affecting this patient. This pear shaped trophozoite, flagellated protozoan is named Giardia Lamblia, which causes Giardiasis. Giardia Lamblia has a very unique way of affecting the body to perform its task. Giardiasis is a waterborne infection and can be transmitted in multiple ways of contamination. It is also the most common intestinal parasitic disease affecting humans. Giardia Lamblia reproduces through binary fission, by attaching to the
Giardiasis is an intestinal disease that has affected humans and mammals since the beginning of human development and creation. Those who become infected with the parasite Giardia lamblia most likely live in developing countries; however, children and adults living in the United States are also found to be affected by giardiasis. In 1681, scientist Antony van Leeuwenhoek discovered the parasite while examining his own waste. Although this was an unusual way to uncover new material, many scientists
protozoan Giardia, and the helminths Loiasis. The Epidemiologic Triangle is a traditional model developed by scientist to study infectious diseases (CDC 2018). The triangle has three vertices that consist of an agent, a host, and an environment. Giardia is microscopic parasite that causes a diarrhea illness known as giardiasis (CDC 2015). Giardia is the most common cause of parasitic gastrointestinal disease. Using the epidemiologic triangle as follows for Giardiasis: Agent- Giardia lamblia (also known
ASSIGNMENT # 1: GENERAL PRINCIPLES OF MICROBIOLOGY 1. Describe the components of the bacterial cell envelope and the primary function of each. The innermost layer of the bacteria cell envelope is the cell membrane. It is a typical phospholipid bilayer, as is found in animal cells. The primary function of the cell membrane is energy production and active transport. The next layer is the cell wall. It is made of N-acetyl glucosamine and N-acetyl muramic acid. Amino acids keep the cell wall together
disinfection. During this stage, disinfectants will be added to kill or inactivate microorganisms that can cause disease in humans. The research on the water sample shows presence of protozoa that cause diseases such as Entamoeba histolytica, Giardia lamblia and Naegleria fowleri (Nemerow, Agardy, Sullivan, & Salvato, 2009). Some protozoa and viruses, which may present in water supplies are extremely harmful. There are two kinds of disinfection which is primary disinfection and secondary disinfection

Gastroenteritis, sometimes referred to as infectious diarrhoea is a common disease that affects millions of people annually. It is a disease caused by viruses, bacteria or parasites that enter the human body and spread, which induce symptoms such as vomiting, diarrhoea, abdominal pain and nausea. Although it is a common occurrence in society and is usually not harmful, cases of gastroenteritis in less developed countries may have more fatal repercussions due to their inability to access ample means
Blufish is a Canadian company founded in Ottawa, Ontario, in 2012 by Youssef Chahrour, a 23 year old business mogul. At Blufish, Mr. Chahrour and his team created a new, innovative product that would assist the lovers of the outdoors in all their water purification needs! Our product is a package of 25 tiny tablets made of chlorine, which purifies unsanitary water. This results in fresh and clean water in a matter of minutes! Since our release in 2013, sales have been increasing in the Canadian
On an average day do you take the time to investigate what you are eating? Do you examine the label fully to see if there are any additives or chemicals in the food? As the world population grows, sustaining it has become a problem. New innovations in technology and farming processes have been a result of the population growth. However these changes are not always for the better, with every new innovation a consequence will follow. Corporate Farming has led to negative health effects in humans.
In today’s society water quality and the possibility of contamination is a major concern. Humans use water to conduct daily activities and it is an essential resource. The world relies on a safe water supply that is potable and pathogen-free. Many countries, like the United States, have made a large effort to make water safe to drink with complex filtration and purification systems. These systems seem to be a given in many first world countries and people don’t have to worry as much as those in developing
Water Regulations (NPDWRs) are the legally enforceable regulations that guard our water system from becoming unclean. The list of contaminants is long there are many that are caused by human or animal fecal matter including but not limited to Giardia lamblia and E. Coli. These can be introduced through lax sanitation practices, sewer overflows, and improper handling of waste byproducts. The process of disinfecting waste can produce byproducts that can themselves cause pollution and
Mega Farms Effects On Water Water pollution has been an increasing problem over the last few years. Pollution itself is when a substance or energy is introduced into the soil, air, or water in a concentrate. Pollution comes in many forms; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few. These pollutants are very detrimental to the environment. Whether they are alone or combined with another form of pollution they are
parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa. They include organisms classified in Amoebozoa, Excavata, and Chromalveolata. Examples include Entamoeba histolytica, Plasmodium (some of which cause malaria), and Giardia lamblia. The symptoms of protozoan infections depend on the type of single-celled parasite involved and where in the body it lives and multiplies. These types of parasites are referred to as protozoa. Protozoa that live in the intestines usually cause
fecal deposits from rodents and birds, accumulated on rooftops during dry periods, may affect the harvested rainwater quality (Ahmed et al., 2008). Microorganisms, such as total coliforms, Escherichia coli, fecal coliforms, Salmonella spp., and Giardia lamblia have been detected at high counts in roof runoff water (Simmons et al., 2001; Ahmed et al.,
The issue that I am investigating is related to the area of study, contemporary and future issues because it is a controversial topic discussed frequently in social and print media and it is related to a contemporary trend in breastfeeding. Another area of study this investigation links to is social/cultural because this has become a large topic that has been widely investigated regarding the development of a child who is breastfed. The research question “is it is best for a child’s development
