Welcome to BIOL 351: Microbiology:




Course description: Microbiology (BIOL 351) is targeted toward those sophomore and junior students with interests in microbiology, cell, molecular and integrative biology and who have strong backgrounds in biology and chemistry. This course can be divided into three parts. The first part provides in-depth coverage of microbiology including: history of microbiology, microbiological methods, prokaryotic cell structure and function, and prokaryotic genetics. The second part of the course goes into the details of microbial diversity including: taxonomy and phylogeny of bacteria, archaea, and viruses; biochemical pathways that are unique to bacteria including aerobic and anaerobic metabolism, phototrophy, and chemolithotrophy; and the role of microorganisms in biogeochemical cycles. The third part of the course focuses on human/microbe interactions including virology, human-microbe interactions, immunology, and the molecular/cellular basis of pathogenesis. Three hours of lecture and three hours of laboratory. Credit not allowed in both BIOL 251 and 351. Prerequisites: BIOL 189, BIOL 196, BIOL 197, CHEM 121. 4 credits.






Course objectives: As a result of taking this course students should:



-Gain a broad knowledge of microbiology, including microbial cell structure, molecular biology, genetics, and physiology of major groups of microorganisms and the roles of microorganisms in ecology and human health

-Understand and appreciate the unique aspects microorganisms particularly Bacteria, Archaea, and viruses



-Master basic language and concepts pertaining to microbiology and molecular biology with the general goal of being able to communicate (reading, writing and speaking) with both scientists and lay people



-Build a foundation in microbiology that can be utilized by students in their in future academic pursuits and professional careers




Learning Outcomes for the course: The School of Life Sciences requires that all students graduating with either a major or minor degree in Biological Sciences;


Understand the nature of scientific knowledge; 1b & d

Understand cell structures and functions; 2a & e

Understand the physical nature of genetic information; 3a, b, d & e

The numbers & letters after each major learning outcome indicate specific learning outcomes associated with Biol 351. These specifics can be found in the full list of outcomes provided on the School of Life Sciences webpage.


Biol 351 also teaches students to explain the diversity and similarity of microbes, including their physiology, mechanisms of pathogenesis and host defenses, and unique ecology.


Biol 351 provides students with opportunities to develop many of the broadly applicable professional skills that are included in the University Learning Outcomes, including Intellectual Breadth and Lifelong Learning Skills, Inquiry and Critical Thinking Skills & Written Communication Skills.

Course materials:




Required text: Brock Biology of Microorganisms, 14th edition, Madigan, Martinko, Dunlap and Clark.

Required laboratory book: Malwane S, Malwane SD. 2017. A Laboratory Manual, Microbiology. 1st ed. Morton Publishing Company, Englewood, Colorado (available in the UNLV bookstore).










Lecture: 70% of your final grade (700 points) will come from the lecture section. Lecture grades will be determined by performance on 3 midterms (154 points each) and a comprehensive final exam (238 points).


Lab: 30% of your final grade (300 points) will be based on performance in lab: Notebooks (150 points), lab quizzes (130 points total), lab conduct (20 points), Lab exam (150 points), and a report on an unknown organism (150 points). The total (600 points) will be divided by 2 and then added to points earned in the lecture.

The total number of points earned will be divided by the total number possible (1000 points) and multiplied by 100% to determine the final grade: A, 100-90%; A-, 89-87%; B+, 86-83%; B, 82-80; B-, 79-77; C+, 76-73%; C, 72-70; C- 69-67%; D, 66-57%; and F, <57%.



Academic Misconduct: Academic integrity is a legitimate concern for every member of the campus community; all share in upholding the fundamental values of honesty, trust, respect, fairness, responsibility and professionalism. By choosing to join the UNLV community, students accept the expectations of the Student Academic Misconduct Policy and are encouraged when faced with choices to always take the ethical path. Students enrolling in UNLV assume the obligation to conduct themselves in a manner compatible with the function of UNLV as an educational institution.

An example of academic misconduct is plagiarism. Plagiarism is using the words or ideas of another, from the Internet or any source, without proper citation of the sources. See the Student Academic Misconduct Policy (approved December 9, 2005) located at:

Incomplete Grades: The grade of `I` incomplete can be granted when a student has satisfactorily completed three-fourths of course work for that semester/session but for reason(s) beyond the student`s control, and acceptable to the instructor, cannot complete the last part of the course, and the instructor believes that the student can finish the course without repeating it. The incomplete work must be made up before the end of the following regular semester for undergraduate courses. Graduate students receiving `I` grades in 500-, 600-, or 700-level courses have up to one calendar year to complete the work, at the discretion of the instructor. If course requirements are not completed within the time indicated, a grade of F will be recorded and the GPA will be adjusted accordingly. Students who are fulfilling an Incomplete do not register for the course but make individual arrangements with the instructor who assigned the I grade.
