If youidentify an Arizona bark scorpionin your house, don't linger or run away. Instead, calmly move away and find something to capture and release it outdoors safely. But you don't want to provoke it in any way. If, by chance, you get stung, seek medical attention if you think you...
Therefore, species identification is important and every attempt should be made to identify Candida to species level. Susceptibility testing of caspofungin has been associated with a level of variation prohibitive for breakpoint setting [3,4]. As there is a high degree of cross-resistance between ...
