Results for drugs to which all bacteria were susceptible S have been highlighted in boldface. All isolates were susceptible to ceftriaxone and levofloxacin, indicating that these agents remain appropriate empirical choices for the treatment of infections with this group of organisms.

Resistance was most frequently observed in Aggregatibacter and Haemophilus species. In addition to valvular infections in the heart, they can also produce other infections such as bacteremiaabscessperitonitisotitis mediaconjunctivitispneumoniaarthritisosteomyelitisand periodontal infections. Culture negative refers to an inability to produce a colony on regular agar plates; this is because these bacteria are fastidious requiring a specific nutrient.

The high failure rate for susceptibility results among these organisms also indicates that current recommended susceptibility methods may not be optimal. Journal of medical microbiology.

The penicillin with the greatest in vitro activity was amoxicillin-clavulanic acid. Ceftriaxone was active against all nacek and was also the most potent cephalosporin Hacrk 900. Since the fastidiousness of HACEK organisms makes resistance testing impractical for many laboratories, and isolates commonly fail susceptibility testing, published reports and guidelines frequently provide the only guidance for antimicrobial selection 1 — 3.
