Bachelor of Science (B.S.) Major in Microbiology (Pre-Physician Assistant Concentration)

Minimum required: 120-124 semester credit hours

General Requirements

  1. The general education core curriculum courses are listed in the degree plan below along with the statewide component code number. See the General Education Core Curriculum section of this catalog for the Texas State requirements and options in the core curriculum, including Honors courses.
  2. Students must complete a minimum of 36 advanced hours (3000 or 4000 level courses).
  3. Students must select a minor from the approved list of Undergraduate Minors. The recommended minor is Chemistry or Biochemistry. Minor and electives should be chosen in consultation with the academic advisor.
  4. The minimum number of hours required for this degree program is 120. The number of elective hours a student completes depends on the number of hours a student may need to achieve the required 120 total or 36 advanced hours.
  5. Students entering Texas State with fewer than 16 credit hours completed after high school graduation will be required to take US 1100. All others will be exempt from taking this course. Students may be required to earn an additional elective to reach the 120 minimum total credit hour requirement for the awarding of a degree.
  6. Nine semester credit hours must be writing intensive (WI).
  7. If two years of the same foreign language were taken in high school, then no additional language hours will be required. In the absence of such high school language, two semesters of the same modern language must be taken at the college level.
  8. Students in this concentration must complete MATH 2328, [BIO 3421 or BIO 3426], and PSY 1300.
  9. For transfer students, 24 semester credit hours in biology, chemistry and physics (or their equivalents) may be transferred from a Texas public institution of higher education for the Biology Field of Study and be applied to the Bachelor of Science degree with a major in Microbiology at Texas State University. More information about the Field of Study is available in the Academic Policies section of this catalog. The transferable Texas Common Course Number (TCCN) is listed below the Texas State University course number in the following course list.

While PHIL 1305 or PHIL 1320 are strongly preferred, the department will allow other Language, Philosophy, and Culture Component Code 040 courses to satisfy this requirement.


Fifteen hours of advanced BIO electives are required of which 11-12 hours must be chosen from: BIO 3430BIO 3430BIO 3442, BIO 4326BIO 4326, BIO 4366/BIO 4166, BIO 4376BIO 4376, BIO 4413, BIO 4446BIO 4446, BIO 4447, BIO 4448, or BIO 4480BIO 4480.


Students may apply only one course from [BIO 3421 or BIO 3426] towards the biology major requirements.


BIO 4299 requires faculty and departmental approval and in order to apply as an advanced biology elective, students must take BIO 4299 two times in succession.
