Microbiology Laboratory

Course Description

Microbiology Laboratory covers microbial morphology, physiology, and taxonomy; relationships of microorganisms to total environment. UWF publishes Co-requisite: MCB 3020 and states that a Material and Supply Fee will be assessed.

Within the SCNS taxonomy, MCB is the Microbiology prefix. The University of West Florida publishes this at 1 semester hour through the Department of Biology, College of Science and Engineering. It is offered at approximately 11 Florida institutions.

⚠ UWF publishes the same two-clause description for this laboratory as for its lecture, so the outcomes and topics below are the standard technique set of an upper-division majors microbiology laboratory rather than a transcription of a published list. The instructor's syllabus governs.

This laboratory differs from the health sciences one in emphasis rather than in technique. The core methods — aseptic transfer, staining, isolation, identification — are shared. What is added here is quantitative and environmental work: growth curves, enrichment culture, environmental sampling, and molecular identification.

⚠ The unknown identification project is the centrepiece at this level, and it is worth treating seriously. Being handed an unlabelled culture and having to reason to an identity — choosing tests, interpreting ambiguous results, deciding when you have enough evidence — is the closest an undergraduate laboratory gets to real diagnostic work.

Expect to work between sessions. Growth curves and enrichment cultures run on the organism's timetable, not the timetable's.

⚠ The contact-hour figure is derived — the University of West Florida publishes none

UWF's catalog publishes a credit value in semester hours, the college and department, prerequisites and co-requisites, and fee notices. It does not publish contact hours, a lecture and laboratory split, or terms of offering for any course. Every contact-hour value in a UWF guide in this repository is derived. The figure applies the convention established for science laboratories at UWF — 45 contact hours for 1 semester hour, matching the live EVR2001L and OCE1001L. A 1-credit science laboratory meeting three hours a week across a fifteen-week term reaches 45, which is the usual shape for a microbiology laboratory in particular, since culture work cannot be compressed. Confirm the meeting schedule with the department.

Resources & Tools

• The laboratory manual the instructor issues — read the exercise beforehand; sessions are timing-constrained and several exercises span days.
• A bound laboratory notebook — at this level the notebook is assessed, and the unknown project depends entirely on a complete record of what was tested and observed.
• Closed-toe shoes, laboratory coat, hair tied back — entry requirements.
• Bergey's Manual of Systematics of Archaea and Bacteria — generally available through the UWF library; the authoritative reference for bacterial identification and the source behind most identification keys.
• ASM protocols and laboratory safety guidelines (asm.org) — free; the standard for undergraduate teaching laboratories.
• NCBI BLAST and SILVA — free; where a 16S sequence becomes an identification.
• Photographs of your own plates and stains — free, and the best revision material for a practical examination.
• CDC (cdc.gov) — free; disease pages, treatment guidance, and the MMWR, which is where outbreak investigations are actually published.
• Florida Department of Health (floridahealth.gov) — free; state and county reportable disease data, and the surveillance reports that make this material local.
• A UWF librarian — included in enrolment; an hour on database searching pays for itself across a whole degree.

Career Pathways

• Medical and clinical laboratory technologist (SOC 29-2011) and technician (SOC 29-2012) — ⚠ Florida licenses clinical laboratory personnel through the Department of Health, and licensure requires an approved programme, not merely coursework. Microbiology is one of the core disciplines of the field.
• Microbiologist (SOC 19-1022) — public health laboratories, environmental laboratories, water utilities, food safety, and pharmaceutical and biotechnology quality control.
• Epidemiologist (SOC 19-1041) — generally requires a graduate degree; the Florida Department of Health and county health departments are the principal state employers.
• Infection preventionist — hospital-based, commonly entered from nursing or medical laboratory science, with CBIC certification. Florida's large hospital systems — AdventHealth, Orlando Health, BayCare, Baptist, Ascension Sacred Heart in Pensacola — all employ them.
• Registered nurse (SOC 29-1141) — microbiology is a prerequisite for essentially every Florida nursing programme, which is why this prefix carries so much enrolment.
• Public health analyst and disease intervention specialist — county health departments across Florida; the state's climate, density, travel volume and mosquito burden make it a genuinely active infectious disease environment.
• Food safety and environmental health inspector — Florida's hospitality and agriculture sectors are large, and both are regulated on microbiological grounds.
• Water quality and environmental microbiology — utilities, springs and estuarine monitoring, and harmful algal bloom response, all substantial in this state.
• Preparation for medicine, dentistry, veterinary medicine, physician assistant and pharmacy — microbiology is prerequisite or strongly expected for all of them.

Special Information

⚠⚠⚠ UWF runs THREE separate microbiology routes — make sure you are in the right one

This is the single most important thing to understand about the MCB prefix, and no course title says it. UWF publishes three parallel microbiology sequences, in two different colleges and three different departments, aimed at three different audiences. They are not interchangeable, and enrolling in the wrong one wastes a term.

• ⚠⚠ Only the 3020 route is upper-division and only it opens the rest of the prefix. MCB4203 Microbes & Disease requires MCB3020 and accepts neither of the others. A biology major who takes the health sciences course has not met the requirement.
• ⚠ The prerequisites tell you the level far better than the titles do. MCB3020 requires general chemistry with its laboratory plus a full year of biology or anatomy and physiology; MCB2010 and MCB2010L publish no prerequisites at all. That gap is the real difference between the routes.
• If you are pre-nursing, check which one your programme names. UWF built MCB1000 for the BSN prerequisite explicitly, but nursing programmes at other Florida institutions frequently name MCB2010C instead, and requirements change between catalog years. Ask your advisor and get the answer against your own catalog year.
• ⚠⚠ Transferring in or out, this is where credit goes wrong. All three carry the word "Microbiology," and a transfer evaluator reading titles rather than descriptions can accept a course that does not satisfy the requirement. Carry a syllabus.
• Most Florida institutions run only one or two of these routes, commonly the integrated MCB2010C. UWF running all three is unusual and is what makes the choice a real one here.

⚠⚠ MCB3020 and MCB3020L bind each other — using two different notations

• The lecture lists the laboratory as an asterisked prerequisite: MCB 3020L*, meaning prior to or during the same term.
• The laboratory lists the lecture in an explicit Co-requisite field: Co-requisite: MCB 3020, which is conventionally the stricter same-term form.
• ⚠ So the pair is bound in both directions, but the two halves are marked differently. Every other reciprocal pair found in this catalog uses the same notation on both sides. The practical effect is the same — take them together — and this guide records the asymmetry rather than smoothing it over.
• Do not plan on splitting them across terms. Whichever notation governs, the registration system is what enforces it, and the safe assumption is that both are needed at once.

⚠⚠ The asterisk in a UWF prerequisite means the course may be taken at the same term

• UWF marks a concurrent course with an asterisk, defined on the catalog's Course Information page as: "This course may be taken prior to or during the same term."
• ⚠ A prerequisite written WITHOUT an asterisk must be completed first; one written WITH an asterisk may be taken in the same term. Reading an asterisked prerequisite as sequential adds a term for no reason.
• UWF also uses an explicit Co-requisite: field, the stricter form — conventionally the same term rather than prior-or-same. Both notations appear in this prefix, and in one case on opposite halves of the same pair.
• The /L notation in a prerequisite — CHM 2046/L, BSC 2011/L — means the course together with its laboratory.
• Confirm with an advisor; the registration system, not the catalog text, is what enforces it.

⚠ A material and supply fee is assessed

• UWF publishes that a Material and Supply Fee will be assessed for this course. It is charged in addition to tuition.
• ⚠ The catalog does not publish the amount. The department or the Cashier's Office is the only reliable source — ask before the term rather than discovering it on a bill.
• The reason is real: media, stains, disposable loops, agar plates and autoclave capacity are consumed per student per session, and microbiology is among the more consumable-intensive teaching laboratories.
• ⚠ Not every laboratory in this prefix carries a published fee. Do not generalise from one course to another — check each entry.

⚠⚠⚠ Microbiology laboratory safety is not the same as general laboratory safety

• You will be culturing live microorganisms. Most teaching organisms are Biosafety Level 1 or 2 and are chosen to be low risk, but they are alive and they multiply — which is exactly what makes the discipline different from a chemistry laboratory.
• ⚠⚠ Aseptic technique protects you and protects the experiment. Contamination is the commonest cause of a failed result in this course, and the same habits that keep a culture pure keep an organism off your hands.
• No food, no drink, no cosmetics, no phone on the bench. Hand hygiene on entering and on leaving, every session, without exception.
• ⚠ Everything that touched a culture is biohazardous waste and goes to autoclave, not to a bin. Learn the disposal stream in week one.
• Report every spill, every broken tube, and every needle or glass injury immediately — including small ones, and including ones you think you handled. Institutions have a procedure for this and it exists to protect you.
• ⚠⚠ Tell the instructor privately, before the term starts, if you are pregnant, immunocompromised, on immunosuppressive therapy, or living with someone who is. This is not a bar to taking the course; it is information that changes which organisms you should handle, and the department can only accommodate what it knows about.
• Ask about vaccination status, particularly hepatitis B, if the course handles clinical material. Health-programme laboratories commonly require it.
• The CDC's Biosafety in Microbiological and Biomedical Laboratories (BMBL) is the underlying authority and is free. The instructor's rules govern in the room.

Course format and position in the curriculum

• Scheduled laboratory sessions with pre-laboratory preparation and written work. ⚠ Microbiology laboratories frequently require returning between sessions to read plates, because cultures grow on their own schedule rather than the timetable's. Ask about this in week one.
• ⚠ No "permission is required" marking appears anywhere in the MCB prefix — enrolment is gated by prerequisites rather than by cohort admission. That is not true of the clinical programmes these courses feed into, which admit by cohort.
• UWF publishes no contact hours, lecture and laboratory split, or terms of offering for any course. Confirm the offering pattern with the department — and note that a course offered in one term only will delay a sequence by a full year if missed.

How Florida course levels affect transfer

In the Florida Statewide Course Numbering System the first digit is the level: 1 and 2 are lower division, 3 and 4 upper division, 5 and above graduate. ⚠ A lower-division course generally cannot satisfy an upper-division requirement, which matters in this prefix more than most — MCB1000, MCB2010 and MCB3020 all teach microbiology, and only MCB3020 is upper division. SCNS equivalency runs on the number and the content, so a course transfers as what it is, not as what its title resembles.

MCB3020L is 1 semester hour at the University of West Florida, through the Department of Biology, College of Science and Engineering.
