Comments:

· 74% of Haemophilus infuenzae isolates were beta lactamase negative (78 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.

· 96% of Moraxella (Branhamella) catarrhalis were beta lactamase positive (27 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.

· 47 isolates of Salmonella species and 2 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.

· 3 Campylobacter species were isolated in 2012.

· 6 Giardia lamblia positive rapid antigens were confirmed in 2012.

· 0 Cryptosporidium positive rapid antigens were confirmed in 2012.

· Beta hemolytic Streptococcus species have not demonstrated resistance to penicillin or ampicillin therefore susceptibility testing is not routinely performed. Of the Streptococcus agalactiae performed on isolates recovered from pregnant penicillin allergic women 100% were Penicillin sensitive, 39% were Clindamycin sensitive and 27% were Erythromycin sensitive. Erythromycin resistant strains cannot be reliably interpreted as Clindamycin sensitive without the addition of the “D Test” to test for inducible resistance.

Beginning in 2007 susceptibility testing will be performed by manual Kirby-Bauer Disk Diffusion Method due to a limitation with the Erythromycin/Streptococcus agalactiae anitibioitc/organism combination using the bioMerieux automated identification susceptibility system.

· Vancomycin resistant Enterococcus species are speciated and the Vancomycin MIC confirmed by alternative methods.
