The purpose of the microbiology research project is to empower you to find the answers to a question you might have about microbiology. It is also to give you a chance to broaden your knowledge about a topic you find interesting. The project is meant to be fairly simple and straightforward, and not too burdensome.
What should you do to complete the project?
- Ask any microbiology question about which you might like to learn more info. For example, maybe you want to know more about Carbapenum resistant Enterobacteriacae (CREs), or nosocomial infections, or autoimmune diseases, or virulence factors of Strepotococcus pneumoniae. The list is endless!
2.I want you to have one peer-reviewed paper and one reliable website source as your references. A peer reviewed article is one that is published in scientific journal. Before publication in a journal, an author’s work is reviewed and deemed scientifically sound, novel, and worthy of publication. (Please note that this process isn’t perfect and not all published work is good work.) Defining a reliable website is more murky water, but try to find info from a site that is published by people with reputable credentials.
- Write a 2-3 page paper about what you learned on your subject. Include a reference page citing your sources. You may use whatever format you prefer.
Parasites are animals or plants that live in or on the host and obtain some kind of benefit from the
host by harming or not harming the host. The term parasite I usually used for any organism that
can infect a host, but conventionally the eukaryotic protozoa and helminthes worms are termed
as parasites. The immunology of parasitic infections was not included in the microbiology
textbooks, but these days it is being included because the parasites are infectious agents that can
be considered as microparasites or macroparasites (Davies et al).
As the term micro indicates, these parasites are smaller in size. They have a tendency to cause
acute and short duration infections. There is an effective immune response to these
microparasites and there are also lesser chances of re-infection.
The term macro here indicates that the parasites will be comparatively bigger in size to the
microparasites. The macro parasitic infections are characterized by the presence of stages as in
each stage only one adult parasite is produced. These infections usually do not threaten life and
build up slowly in the body. The immune response to these kinds of infections is different from
the immune response to the microparasites. Here, the immune response works in a specific way
called the concomitant immunity, which means that the immune response does not allow any re-
infection and at the same time does not curtail the ongoing infection. Immunity does not last
after the infection fades away and the duration of these infections is longer than the micro
Although there are many parasites that infect humans and animals, a few have gained more
notice because probably they infect people more frequently than the other parasites.
Leishmaniasis is a disease caused by Leishmania. Leishmania has many species, such as mexica
braziliensis, donovani, tropica, major, and chagasi. The Chaga’s disease is caused by
Trypanosoma cruzi. Malaria, a very common disease all over the world, is caused by the parasite
Plasmodium that is available in many species, such as vivax, malariae, falciparum, ovale, etc.
Trypanosoma gambiense and Trypnaosoma rhodesiense are the causative agents of sleeping
sickness. Schistosomiasis is caused by Schistoma and lymphatic filariasis by Wuchereria
Brugia.Onchocerciasis is caused by Onchocerca volvulus (Davies et al).
