: Long, whip-like proteins used for bacterial motility and chemotaxis.
Lacks a cell wall entirely. Naturally resistant to beta-lactam antibiotics. Causes "walking" pneumonia.
Cover healthcare-associated infections and outbreak investigation, emerging and re-emerging infectious diseases, bioterrorism agents, and infection prevention and control (including sterilization, disinfection, and personal protective equipment).
Recombinant viral variants are also emerging, as demonstrated by the identification of Coxsackievirus A6 subclade D3/Y during a hand-foot-and-mouth disease outbreak in India.
: Entry via receptor-mediated endocytosis or direct membrane fusion. medical microbiology lecture notes ppt updated
Mycology addresses fungal pathogens, which have seen a surge in clinical relevance due to expanding immunocompromised patient populations.
: Leads to typhoid fever and intense diarrhea.
: Causes urinary tract infections and food poisoning.
A comprehensive lecture series should be structured around these main modules. 1. General Microbiology and Bacteriology : Long, whip-like proteins used for bacterial motility
: Microscopic single-celled organisms. Key examples include Plasmodium species (malaria) and Entamoeba histolytica (amoebiasis).
has emerged as a promising alternative. Bacteriophages—viruses that specifically infect bacteria—can be selected in days or weeks rather than decades required for new antibiotic development. Phages can be combined into cocktails and are particularly effective against biofilm-associated infections, which are notoriously difficult to treat. Research on mixed biofilms containing both Staphylococcus aureus and Candida albicans has shown that combining phages with antibiotics and antifungals yields the best results.
A partially double-stranded DNA virus utilizing reverse transcriptase. Transmitted via blood, sexual contact, or perinatally; carries a high risk of hepatocellular carcinoma. RNA Viruses
Skin infections, endocarditis, osteomyelitis, toxic shock syndrome Nafcillin; Vancomycin or Daptomycin for MRSA Streptococcus pneumoniae Gram-positive lancet-shaped diplococci Community-acquired pneumonia, meningitis, otitis media Penicillin G, Ceftriaxone, or Amoxicillin Neisseria meningitidis Gram-negative kidney-bean diplococci Causes "walking" pneumonia
Ascaris lumbricoides : Large intestinal roundworm capable of pulmonary migration.
Surface proteins or appendages that bind to specific host cell receptors.
: Reduction of microbial load on living tissue using chemical agents.
: Amplifying specific microbial DNA or RNA sequences for rapid identification. Multiplex PCR panels allow for simultaneous screening of multiple pathogens.
Entamoeba histolytica: Fecal-oral transmission; causes amoebic dysentery.
