NOTES:

 

  • 70% of Haemophilus infuenzae isolates were beta lactamase negative (88 isolates tested). Beta Lactamase negative indicates probable susceptibility to penicillin, ampicillin and 1st 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.
     
  • 98% of Moraxella (Branhamella) catarrhalis were beta lactamase positive (41 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, 3rd generation cephalosporins, macrolides, quinolones and trimethoprim/sulfamethoxazole.

     
  • 30 isolates of Salmonella species and 12 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.
     
  • 4 Campylobacter species were isolated in 2007.
     
  • 4 Giardia lamblia positive rapid antigens were confirmed in 2007.
     
  • 2 Cryptosporidium positive rapid antigens were confirmed in 2007.
