Cestode infection can be diagnosed conventionally through physical examination by the presence of segments in the anus of an infected animal (Fox, 2010; Schoenian, 2013; Smith & Sherman, 2009; Soulsby, 1982), or existence of mature segments in their excrement (Urquhart et al., 1985). These proglottids looks like cooked rice grains (Soulsby, 1982). Fecal flotation segregates the fecal debris and the eggs which float to the top when emulsified in liquids with high specific gravity through standing or centrifugation (Kaufmann, 1996). Flotation principle is generally useful in finding cestode and nematode eggs, as well as protozoan cysts (Roberts & Janovy, 1996). This test can see the eggs when viewed under the microscope; however, this test is not definitive (Schoenian, 2013). Determination of parasitic eggs are possible by the examination of thin smear of feces which is emulsified. However, this is only efficient if the concentration is high and there is difficulty in identifying the eggs due to the debris present (Kaufmann, 1996). This examination suited when rapid examination is needed (Soulsby, 1982). Roberts and Janovy (1996), affirmed that negative results are inconclusive, however those that are positive are as credible as those that gathered in concentration techniques that are …show more content…
Examples of nonchemical medications used to kill adult tapeworms are pumpkin seeds, powdered areca, kousso, turpentine, pomegranate root bark, and male fern (Schoenian, 2013). In the Philippines, local plants used are watermelon seeds which is very specific for tapeworms, custard apple, makabuhay, kamachili, kakawate, aludig and jackfruit which are broadly against common intestinal worms (Mateo cited in International Livestock Research Institute-International Fund for Agricultural Development-Philippine Council for Agriculture, Forestry and Natural Resources Research and Development,
The Unknown Identification Lab was an experiment that provided the opportunity to apply all the tests that were learned in the semester of lab, to identify the two bacterias that remain unknown. Gram- staining and two other tests will be used to identify the unknowns. This experiment is crucial to the understanding of each test, and can benefit in the ability to identify the characteristics of specific bacteria. Having a clearer understanding of the bacteria can further the research of bacteria for medicine, such as antibiotics. The understanding can also help the development of research in the environment.
Researchers used nursing theories to help guide research on complicated phenomena(Connelly, 2014). After reviewing evidences collected on the topic "Antibiotic therapy and Clostridium difficile infection (CDI)", the most common theories that have been cited are, exposure to antibiotic, especiallyin patients that have been previously diagnosed with bacterial infections(respiratory, urinary and osteoarticular infections) are significanly at risk for acquiring CDI and theory for prevention cited was implementation of an Antibiotic stewardship program. Inaddition,hand hygiene, contact precaution and environmental cleaning protocols where other interventions listed. Concept Definitions Exposure to antibiotic- is operationally defined as the last time within 30 days a hospitalized patients received antibiotic therapy before the current hospital
Materials and Methods To start with, the unknown bacteria # 710 broth had to be successfully isolated on an EMB and MAC agar plate. Using aseptic technique by sterilizing the wire loop with Bunsen Burner between inoculations and flaming the opening of the test tubes before inserting in the loop with the bacteria. The streaking technique used was to isolate the colonies on the agar plates. In addition, the streak plates had to be incubated in a upturned position for 24 hours in a hot temperature incubator at 37 degree Celsius. Bacteria need a favorable condition to grow in.
Staphylococcus epidermidis is the organism that was identified based on the tests that I had conducted. The tests that I used to identify this organism were the coagulase test and the catalase test. My bacterium was beta hemolytic as well. First, a gram stain had to be done to determine whether the organism was a gram positive organism or a gram negative organism. This determined which set of tests that had to be done.
When given an unknown bacteria there are a multitude of steps one must go through to be able to correctly identify what bacteria was given. It is important to correctly identify the bacteria because some bacteria are more harmful than others. The gram stain is the first test that should be performed because it helps narrow down the possibilities by telling one whether the bacteria is gram positive or gram negative. After this test is performed, one shall place bacteria on/in Mannitol Salt agar, MacConkey agar, Eosin Methylene Blue agar, Urea agar, Simmon’s Citrate, Purple Beef broth with Lactose and finally Purple Beef broth with Sucrose. A streak plate should also be made up, this helps one identify the morphology of the colonies.
Have you ever wondered how much salt it takes an ocean to float any substance? Well i have and i wanted to figure that out. Well the thing that makes something float is called density. Density is the weight or mass something has.
INTRODUCTION Giardia Lamblia is a protozoan parasite. About 200 million people had infected in the world but this value just an estimate since that only 500 000 of new cases reported in a year. Previously, higher prevalence of occurance in the developing countries (20% and 30%) compare to developed countries (2% and 5%) (Wilson, 1984; Farthing, 1994).. Malaysia was considered as the developing country.
I first saw the warm in the beaker on the bottom crawling around and balling up. Next, I used a pipet to suck one of the worms out. I put my worm on my plastic piece that was filled with spring water. The water was full enough to fill the container about half way. I put plenty of water so the worm would not dry up and die.
There are many healthcare disparities involving parasitic infection. One disparity, for example, is that any one can get parasitic infection, it is so easy to be infected by a parasitic infection. Also, to really prevent one from getting a parasitic infection, they would have to be extremely cautious on the food they are eating and the water they are drinking. It is more common in regions of tropical or subtropical to avoid getting infected. We can also get infected through our pets and the disparity in this is that its hard to keep up with everything to avoid getting infected with parasitic
Pediculus humanus capitis is the scientific name to what is most commonly known to us as the head lice. The head louse is a Eukaryote that belongs to the Animalia kingdom and is categorized as an obligate parasite. An obligate parasite needs a host in order to complete its life cycle. Without a host the head lice are unable to reproduce and survive. Head lice must feed off another living body to survive.
Among the millions of Americans that are sexually active a sweeping pathogen is hard at work. Chlamydia, a sexually transmitted bacterial infection, has topped the list on a global scale as being the most prevalent sexually transmitted infection (STI). One of the key reasons for this is that this bacterium has the ability to go unnoticed, and as a result, leaves in its wake numerous infected hosts who in turn unknowingly spread the disease further. Screening practices for chlamydia along with education about reproductive health and human sexual behavior are lacking in impoverished regions and without these preventative measures chlamydia continues to gain a foothold.
What remains are stool bugs. The stool bugs are then placed in capsules where they are intended to be swallowed
Intially, a human drinks water contaminated with water fleas, which have eaten the Guinea worm larvae. The human digestive system destroys the fleas, but the Guinea worm larvae survive. A year after infection, the larvae are fully grown and females make their way to the surface of the skin.
Some of the forensic and pathology experts cast doubt on coroner John Penistan’s key forensic evidence used to convict Truscott.” This case haven been taken many years ago had many doubts surrounding it, “in 1996, Penistan had second thoughts and published a review of his autopsy that opened the time frame to a 12-hour window.” Since the forensic evidence was the determining factor for Truscott’s conviction, many years later there was more research done. Dr. Neal Haskell, a forensic entomology professor “testified that larvae must have been deposited on the 12-year-olds body between 9pm and 9:30pm.” With that being said this put weight on the time interval Penistan originally stated.
Nguyen Nguyen Professor Microbiology 1 May 18th, 2016 01MW – Staphylococcus Epidermidis The Staphylococcus Epidermidis is classified as bacteria. Scientists reckon it to Firmicutes phylum and adjust it in Bacillales order of Bacilli class. This bacteria belongs to Staphylococcaceae family.
