Drisdelle, Rosemary (2010).  Parasites:  Tales of Humanity’s Most Unwelcome Guests. 

In this course, we will be concentrating on the biology of those parasitic organisms which are of medical or veterinary importance. The emphasis of the course will be on natural history, so you will be responsible for the following information pertaining to each parasitic organism covered in class: 1)Binomial nomenclature; 2)Phylogenetic relationship; 3)Life cycle; 4) Preferred definitive host(s); 5)Intermediate and/or vector host(s); 6)Geographical locations where the parasite is found and is endemic; 7)Organs affected; 8)Symptoms associated with infection; and 9)Drugs used in treatment.

DETAILS ABOUT THE LECTURE

Your lecture grade will be based on the following:

1.   Weekly quizzes lasting (maybe) 10 minutes, usually on Fridays, covering the previous week’s lecture material:  These quizzes will be multiple-choice, matching, and short answer.  Cumulatively, they will count 1/6 towards your final grade;

2.   FOUR MIDSEMESTER EXAMS: Each of these exams will consist of essay and identification/practical questions. Each of these exams will be comprehensive and count 1/6 towards your final grade;

3.     A final exam scheduled during Final Exam Week. This exam will count 1/6 towards your final grade. 

DETAILS ABOUT THE LAB

You will be learning techniques which are pertinent to the study of parasitology. These include and will not be limited to the following:

1.     Preparation of permanent slides of stained helminths;

2.     Preparation of wet mount of fecal smears;

3.     Removal of parasitic organisms from dissected host animals;

4.     Concentration of ova by fecal flotation;

5.     Preparation of a smear of parasitic protozoa from earthworms.

The collection of data is a cooperative effort, in which the class will analyze data collected by the entire class.  There are two particular experiments which I would like you to write up as lab reports:  a mosquito bioassay, in which you test the efficacy of at least two larvicides, and a survey of parasites among the centrarchids (sunfish) of Beaver Lake, one of the impoundments located at Shelby Farms.   

With the possible of exception of Giardia lamblia, you will NOT be exposed to human pathogens. Nonetheless, you will be required to follow rigorous safety procedures.

Your final grade will be based on the following:

1.     Weekly quizzes of short answer and identification questions, covering the previous lab’s specimens.  Collectively, these quizzes will count 1/5 towards your final grade;

2.     Two lab reports based on data collected by the entire class.  These experiments will be cooperative laboratory experiences, in which all members of the class will collect data.  You have the option of submitting a group paper, in which a group consists of 2 to 4 students, or you can submit a paper written solo.  The written papers are to be written in the same format for articles appearing in the Transactions of the Tennessee Academy of Science. Grading of the laboratory reports will be on the basis of spelling, grammar, clarity, and content, whereas grading of the oral presentation will be based on clarity, accuracy, and completeness of analysis.   Each report will count 1/5 towards your final grade;

3.     A midterm exam consisting of short answer and identification questions.  This exam will count 1/5 towards your final grade;

4.     A final exam consisting of short answer and identification questions.  This final exam will count 1/5 towards your final grade.

Some of the experiments will require more time than a single four-hour block of time allows. You will be expected to collaborate in order to complete the work. Furthermore, participation in all field trips is mandatory.

The grading scale for the lecture and the lab will be the following:

A = 3.5 - 4.0
B = 2.75 - 3.49
C = 2.00 - 2.74
D = 1.00 - 1.99
F = <1

CLASS ATTENDANCE POLICY

Every student is expected to attend classroom and laboratory periods regularly. A student who has been absent, even for a legitimate cause, is under obligation to make up the work. Any student who has missed a total of eight hours of class may be dropped from the course, with a mark of "F", at the discretion of the teacher.
