BIOL 211 Lecture Notes - Lecture 24: Calcification, Obligate Aerobe, Necrosis
Document Summary
Prevention of penetration of the drug to its target site. Hereditary drug resistance (r) factors are carried by plasmids and transposons. Can be anywhere: respiratory system, wounds, digestive system, genitourinary tract, nervous system, lymphatic/blood system. Bacterial meningitis: severe infection of meninges of the brain. Otitis media: infection/inflammation of the middle ear. Uti: infection of bladder, urethra, kidney, or ureters. Respiratory tract infections: sore throat, bronchitis, pneumonia. Infections of upper respiratory system (head & neck) Pneumonia + tb = can be fatal. One of the most important pathogens of the head and neck. Destructive enzymes or toxins that damage/kill host cells. Structural components of outer cell wall allow evasion of host defenses. Uses ab subunits to release toxins, could potentially cause heart failure. Formation of tubercle in lung, walled-off lesion resembling a bump or knob. Many anaerobic wounds allow growth of obligate anaerobes = clostridium tetani. Infections can lead to good conditions for facultative anaerobes = staph aureus.
