Inhibition of cell wall synthesis (penicillins), protein synthesis (tetracyclines), nucleic acid replication (quinolones).

Protozoa: Intestinal ( Giardia lamblia , Entamoeba histolytica ) and blood/tissue pathogens ( Plasmodium species causing malaria, Toxoplasma gondii , Leishmania ).

: Inhalation, ingestion, trauma, sexual contact, insect bites. medical microbiology lecture notes ppt

Where the pathogen lives (humans, animals, environment).

Bacteriology forms the largest portion of standard medical microbiology curricula. Medical practitioners categorize bacteria based on physical structures and genetic traits to guide rapid empiric treatment. Where the pathogen lives (humans, animals, environment)

Candida albicans (thrush, yeast infection), Cryptococcus neoformans (meningitis), Aspergillus (aspergillosis). 7. Parasitology: Protozoa and Helminths

Specific viral surface proteins bind to complementary receptor sites on the host cell membrane.

Fluoroquinolones (e.g., Ciprofloxacin) inhibit DNA gyrase and topoisomerase IV, blocking replication. Rifampin inhibits bacterial RNA polymerase, preventing transcription.
