Doxycycline: 53ug/ml
8x8 =64>53
False
It is proven, that animal products can transfer antimicrobial resistance to people, the most important and versatile vector of it is the E. coli.
True
In case of time dependent bactericidal antibiotics their maximum concentration should be at least six times higher in the treated compartment then the MIC volume of the given antibiotic agent for the given infectious bacterium isolate
False
Multiple causes can be present in the background of BRDS, while the treatment of which the bacterial resistance is rare. Most of the empirically suitable antibiotics can
treat the disease in case of P. multocida, M. haemolytica and M. bovis infectious
background as well
False
In case of bovine P. multocida respiratory disease the MIC value for ceftiofur is 0,004 mg/μl. The concentration reached in the PELF, in the blood and in the pulmonary interstitial fluid is higher than the MIC value for more than 8 days. This means a correct drug choice for the treatment of the infectious disease.
