Basic Review of the Microbiology Lab for 2025

By Suzane Silbert, PhD

January 16th, 2025

Dr. Suzanne Silbert, Microbiology Director for Tampa General Hospital, presents this introductory talk on the basics of the microbiology lab for 2025. Dr. Silbert begins with an overview of clinical microbiology, and then reviews the basic classification standards for bacterial organisms, viruses and fungi. She then goes on to discuss culture cultivation techniques, including the use of liquid, solid, or semi-solid media. The speaker then covers identification systems for bacterial organisms, including MALDI-TOF, Disk-Diffusion, and molecular diagnostic techniques.

Gram Negative Bacterial Resistance

By Rebecca Bruning, PharmD, BCIDP

January 9th, 2025

Dr. Becca Bruning, Infectious Diseases Pharmacy Specialist at the Moffitt Cancer and Research Institute in Tampa, FL, takes a deep dive into the subject of resistance mechanisms for specific gram negative bacteria. Dr. Bruning begins her talk by discussing the primary resistance mechanisms, including porin channels, efflux pumps, and other target sites. Extended spectrum beta-lactamases (ESBLs) are next covered, including typical bacterial species, identification techniques, ESBL testing, and the use of Piperacillin-tazobactam and carbapenems. Next, Dr. Bruning mentions AmpC-type resistance, and identifies the “HECKYES” bacteria. Pharmacokinetic and phamacdynamic considerations are explored, and specific antimicrobial agents are discussed. Lastly, Dr. Bruning covers the use of carbapenemase testing including the modified hodge test and the Carba-R test.

Anaerobic Infections

By Ju Hee Katzman

January 3rd, 2025

Dr. Ju Hee Katzman, Infectious Diseases attending and Program Director of the USF ID Fellowship Program, reviews anaerobic infections in this new presentation. In a question and answer format, Dr. Katzman covers the medically significant anaerobic bacteria and categorizes them by their clinical morphology. Next, she covers several clinical scenarios where the treatment of anaerobic infections is indicated, and those in which it is less advisable. Lastly, Dr. Katzman covers specific anaerobic infections, including the Clostridia, the anaerobic gram positive cocci, Bacterioides, Propionibacterium, and Actinomyces.

HIV Dermatology

By Patrick Danaher, MD

November 29th, 2024

Dr. Patrick Danaher, Infectious Diseases Clinician at the USF Morsani College of Medicine, discusses the various dermatologic manifestations of HIV in this recorded session. Among the topics discussed includes genital herpes disease, Zoster, Mpox infections, MRSA skin lesions, and Kaposi sarcoma. The lecture is presented in a case-based format.

The Spirochetes: Leptospirosis and Relapsing Fever

By Richard L. Oehler, MD

November 21st, 2024

Dr. Richard L. Oehler, Professor of Medicine at the Division of Infectious Diseases, Morsani College of Medicine, reviews two important clinical syndromes caused by Spirochetes. Dr Oehler begins by presenting an actual clinical case of Leptospirosis in a returning traveller from the Caribbean. He then discusses the epidemiology of Leptospira, a widespread zoonotic pathogen that favors temperate and topical climates worldwide. He then relates the life cycle, means of transmission, microbiology, clinical manifestations, and most relevant diagnostic studies. He concludes the leptospirosis section by discussing treatment and prevention. The second case he discusses is a febrile illness in a returning traveler from Jordan. Dr. Oehler goes on to discuss the epidemiology and classification system for relapsing fever (RF), and its broad categorization into tick-borne (endemic) and louse-borne (epidemic) forms. He further describes the characteristics of the soft-shelled Ornithodoros ticks and the Human Body Louse, and differentiates the Hard Tick Relapsing Fevers such as Borellia miyamotoi and B. lonestarii. He then reviews the clinical manifestations, diagnostic criteria, and treatment options for each form of RF. Lastly, Dr, Oehler breaks down treatment and prevention strategies for each form of relapsing fever.

Syphilis: An Epidemic

By Kirtan Amin, MD

November 15th, 2024

Dr. Kitan Amin, Infectious Diseases Fellow at the USF Morsani College of Medicine, presents this talk on the current state of syphilis in the U.S. Dr. Amin begins by discussing the epidemiology and classification of Treponemial organisms. The history of Syphilis is then reviewed, including the origins of the disease in the new world and the unfortunate history of the Tuskegee trials. Next, the clinical manifestations of Syphilis are detailed, including primary, secondary, late latent, and neurosyphilis. The unique effects of Syphilis in HIV are also covered. Lastly, syphilis testing and treatment are reviewed, including the effects of the recent Benzathine penicillin shortage and alternatives to Penicillin for treatment.

Pneumocystis Pneumonia in Cushings Disease

By Cilia Nazef, MD

November 8th, 2024

Dr Cilia Nazef, Infectious diseases Fellow at the University of South Florida Morsani College of Medicine, explores how Pneumocystis jirovecii, a fungal infection typically affecting immunocompromised patients, can also affect patients suffering from hypercortisolism. Dr. Nazef begins by examining different cases of Pneumocystis jirovecii Pneumonia (PJP) in patients with Cushings disease. Next, she further explains the immunologic basis behind how the hypercortisol state induces immunosuppression. Dr. Nazef closes by examining the basis for PJP prophylaxis in Cushings disease patients, and the shortcomings of the current literature in advocating prophylaxis options.

HIV in Older Patients

By Todd Wills, MD

October 29th, 2024

Dr. Todd Wills, Professor of Medicine with the Morsani College of Medicine at the University of South Florida, reviews the unique complications and issues that can occur in the elderly HIV patient. Dr. Wills begins by reviewing the epidemiology of HIV by age group, including the fact that the HIV positive population is growing older with time. Dr. Wills also discusses issues regarding polypharmacy and medication tolerability in the older patient. Next, the speaker relates how the high prevalence of chronic diseases affect the HIV positive patient’s prognosis. HIV positive elderly patients can suffer not just from frailty, but from cardiovascular disease, diabetes, osteoporosis, and cancer. Dementia can also affect an elderly HIV paitent’s overall wellness and compliance with antiviral therapy. Dr. Wills also covers the assessment of bone density in elderly HIV positive patients. Lastly, Dr. Wills discusses HIV positive patient life expectancy in the modern age of antiretroviral therapy. The lecture is updated for 2024.
