NOTES:

• 69% of Haemophilus infuenzae isolates were beta lactamase negative (122 isolates tested). Beta Lactamase negative indicates probable susceptibility to penicillin, ampicillin and 1^st generation cephalosporins. Beta lactamase positive indicates probable resistance to ampicillin, amoxicillin and first generation cephalosporins. Recommended therapy is combination therapy or a third generation cephalosporin.
  
• 100% of Moraxella (Branhamella) catarrhalis were beta lactamase positive (32 isolates tested). Beta lactamase positive indicates resistance to penicillin, ampicillin and first generation cephalosporins. Several beta-lactams are effective including beta lactam/Beta Lactamase inhibitory combinations, 3^rd generation cephalosporins, macrolides, quinolones and trimethoprim/sulfamethoxazole.
  
• 40 isolates of Salmonella species and 10 Shigella species were recovered. Susceptibility testing is not routinely performed on intestinal sites. Extraintestinal sites are tested against ampicillin, trimethoprim/sulfa and a third generation cephalosporin. Intestinal source isolates will be tested per telephone request.
  
• 11 Campylobacter species were isolated in 2008.
• 5 Giardia lamblia positive rapid antigens were confirmed in 2008.
  
• 0 Cryptosporidium positive rapid antigens were confirmed in 2008.
