Explore medical microbiology, host–parasite interactions, and how pathogens cause disease; differentiate extracellular and intracellular organisms, virulence factors, attenuation, vaccines, infection types, and portals of entry including food poisoning.
Learn essential medical terms and definitions used in clinical bacteriology, including infections, toxins, immunity, epidemiology, etiology, and laboratory terminology.
Explains the six steps of infectious disease—from transmission and adherence to colonization, damage, exit, and survival—with examples of pathogens and virulence factors.
Explore microbial toxins, comparing exotoxins and endotoxins, their modes of action, heat stability, immunogenicity, detection tests, and representative bacterial sources.
Explore how antibiotics work, their classes and modes of action, and how natural and acquired drug resistance develops through mutations, plasmids, and efflux mechanisms to inform responsible use.
Explore streptococcus pneumoniae, the pneumococcus, gram-positive, lancet-shaped diplodocus bacteria with a polysaccharide capsule, alpha-hemolysis, bile salt and optochin sensitivity, and its key diseases such as pneumonia.
Learn how Vibrio cholerae, a gram-negative, curved, motile bacterium, causes cholera through toxin-mediated diarrhea and dehydration, and how diagnosis, prevention, and treatment reduce spread.
Escherichia coli, a gram-negative enterobacteriaceae, presents as lactose-fermenting coliform; key tests include IMViC and MacConkey agar, with ETEC, EHEC, EPEC, and Entero Invasive E. coli causing UTI, meningitis, and diarrhea.
Explore salmonella infection caused by salmonella typhi, its enteric fever pathogenesis, clinical features, and diagnosis with culture, differential and selective media, and antibiotic treatment.
Explore clostridium species, gram-positive, spore-forming bacteria found in soil and the gut that produce potent exotoxins and enzymes, causing tetanus, botulism, gas gangrene, and pseudomembranous colitis.
Explore Neisseria species, including pathogenic Neisseria meningitidis and Neisseria gonorrhoeae, their oxidase positivity, diplococci morphology, growth requirements, transmission, clinical presentations, diagnostic tests, and prevention and treatment strategies.
Examine mycoplasma biology, its lack of a cell wall, and growth on cell-free media, along with walking pneumonia and genital infections. Review diagnosis and tetracycline-based treatment, including penicillin resistance.
Pseudomonas aeruginosa is opportunistic, aerobic gram-negative rod that causes nosocomial infections, forms biofilms and pigments, and relies on virulence factors such as pili, endotoxin, and exotoxins; diagnosis uses oxidase tests.
Chlamydia is a gram-negative obligate intracellular bacterium that cycles as elementary and reticulate bodies to cause ocular, genital, and respiratory infections.
Explore how Campylobacter causes inflammatory diarrhea and dysentery in humans, a common gram-negative, microaerophilic, curved pathogen transmitted through undercooked meat, raw milk, or contaminated water.
Identify Legionella pneumophila as a gram-negative, motile, facultative intracellular bacterium causing Legionnaires' disease and Pontiac fever via aerosols; diagnose with culture and fluorescent antibody testing, treat with macrolides or fluoroquinolones.
Helicobacter pylori is a gram-negative curved rod with flagella that survives acidity via urease; identified by urease tests and linked to chronic gastritis, ulcers, and gastric cancer.
The introduction to Clinical Bacteriology (medical microbiology). It is a course for those interested in clinical microbiology and to understand the progression of diseases and illness. This course introduces students to the microbial species particularly bacteria that cause human disease. This course is comprised on 17 lectures and divided into two sections. First section includes introduction to medical microbiology, medical terminologies, mechanism of drug resistance phenomena, virulence factors, bacterial toxins, and the second section comprised on the characteristics (morphology, cultural, biochemical traits, pathogenesis, pathology, epidemiology, risk factors, diagnostic procedures, prevention, and treatment) of clinically important bacterial pathogens such as Escherichia coli, Streptococcus spp, Helicobacter pylori, Clostridium spp, Neisseria, Salmonella, Mycoplasma, Vibrio cholerae, Campylobacter spp, Legionella pneumophila, Pseudomonas aeruginosa, and Chlamydia.
The total time length of this course is 3 hours and the first section should follow step by step to develop the fundamental understanding of clinical microbiology. While from the second section, you can choose to pick any bacterial pathogens of your interest to learn first. This course is designed in a manner to develop the understanding of this field from one concept to another and appropriate for beginners, intermediate students, and laboratory technologists. The goal is to make this course interesting, and easy to understand and to share all my knowledge related to clinical bacteriology.
