-Strep pyogenes (B-hemolytic group A) -inactivated by penicillinase (B-lactamase): -S. pneumoniae: becoming increasingly resistant to penicillins and cephalosporins due to protein -methicillin, oxacillin, cloxacillin, dicloxacillin, nafcillin -extend activity spectrum to gram-negative organisms: -resistance in B-lactamase producing organism -clavulanate (amoxil) and sulbactam (ampicillin) -for management of staphylococci, H. influenzae, M. catarrhalis, anaerobic organisms Cephalosporins
-commonly and safely used by pts with history of penicillin rashes highly effective against gram-positive organisms such as streptococci, pneumococci except for penicillin-resistant strains, and staphylococci except MRSA -highly active against gram-positive cocci -H. influenzae and M. catarrhalis including pen-resistant strains -penetrates blood-brain barrier fairly well -cefixime:-oral agent highly effective against H. influenzae and M. catarrhalis -parenteral agent effective against H. influenzae, M. catarrhalis, S. pneumoniae, N. -first choice for treating patients with intracranial and orbital complications of acute -usually less active against gram-positive bacteria -anaerobic bacteria are also relatively resistant A n ti b i o t i c s
-active against S. pyogenes, most S. pneumoniae organisms, S. aureus, H. influenzae, B. fragilis and most anaerobic organisms and the coliforms including P. aeruginosa -used as single agent against infection by unidentified organisms but CSF penetration is not assured Macrolides
-effective for respiratory infections d/t streptococci, most pneumococci, mycoplasmata and chlamydiae, legionellosis, diptheria, and pertussis -extend antimicrobial activity to include H. influenzae and M. catarrhalis Clindamycin
-highly active against gram-positive cocci, including many but not all strains of penicillin-resistant -effective against S. aureus and anaerobic infections of the aerodigestive tract (B. fragilis) Tetracyclines
-effective against Mycoplasma, Chlamydia, and Legionella -stain enamel in forming teeth: avoided in children younger than 10 and pregnant women Quinolones, Fluoroquinolones
-potential for cartilage damage and arthropathy in children -levofloxacin, gatifloxacin, gemifloxacin: -for respiratory and pharyngeal infections -effective against B-hemolytic S. pyogenes, S. pneumoniae, S. aureus, H. influenzae, M. catarrhalis , Mycoplasma, Chlamydia, Legionella, Bordetella pertussis Vancomycin
-highly active against gram-positive cocci including MRSA, penicillin-resistant strains of pneumococci, -high concentrations in patients with renal impairment can cause ototoxicity Metronidazole
-highly active against anaerobic bacteria -all aerobic bacteria are resistant to this agent Aminoglycosides
-used against P. aeruginosa and other hospital-acquired infections m a n a g e m e nt o f H . i n f l u e n z a e b u t n o t o f p n e u TREATMENT STRATEGIES
Otitis Media
-S. pneumoniae, H. influenzae, M. catarrhalis -first line:-amoxil:-most strains of S. pneumoniae -H. influenzae (20% resistant) and M. catarrhalis (80% resistant) -high dose penicillin for penicillin resistant organisms -vancomycin, levofloxacin, gatifloxacin, moxifloxacin, gemifloxacin Sinusitis-acute: -same bacteria as in OM
-pneumococcal infection suspected Rx ceftriaxone, cefuroxime or trovafloxacin -chronic:-anaerobes and S. aureus Pharyngitis
-also N. gonorrhoeae, Mycoplasma, Chlamydia and H. influenzae Tonsillitis-frequently caused by S. pyogenes
-pneumococci and H. influenzae tend to intracranial extension Rx ceftriaxone -chronic suppurative otomastoiditis including cholesteatoma: S. aureus, Proteus, B. fragilis and other Suppurative Otitis
-polymyxin for pseudomonal infection and neomycin for S. aureus, Proteus organisms and others

The nervous system consists of the brain and the spinal cord (the central nervous system or CNS), as well as all the nerves in the body. 2.
