In addition, our case highlights the difficulties of laboratory detection of h-VISA-phenotype, particularly when it is unstable and arises from a fully susceptible VSSA isolate (vancomycin MIC ≤1 μg/ml) under treatment with vancomycin.
Clearly it is not, nor do the team know why their absence prolongs the period that the disease is latent.That is an important lesson about the difficulty of extrapolating laboratory results into the real world.
Graham replied to Findlay regretting that "although we have been engaged in this sort of investigation for the past few years, we do not think that, at present, much help has been given to the clinician"—but the reason he gives for this ("mainly because of the difficulty of the laboratory methods involved") indicates that they are beginning to shift away from Findlay's position.
At this level, the book is a fascinating account of the difficulties of designing laboratory experiments to dissect unambiguously something as complex and variable as behavior -- even the behavior of a fish with a brain the size of a pinhead.
1, 2 Widely distributed in Southeast Asia and northern Australia, this Gram-negative bacillus can cause a diversity of acute, sub-acute, and chronic clinical manifestations, which are frequently unrecognized because of the difficulties of accessible laboratory diagnosis.
Several features of the outbreak are unusual or give cause for concern: human-to-human-to-human transmission, possible nosocomial transmission, occurrence of mild and asymptomatic cases, and difficulties of establishing laboratory confirmation of likely and possible cases (which also prevented genotypic matching of specimens from primary and putative secondary cases).
This work demonstrates the difficulty of relating adiabatic laboratory experiments to the spontaneous heating and ignition of piles of stored coal.
A pervasive difficulty of using such laboratory models is that these models may not accurately model 'natural' infections.
The major drawbacks of the visual MVD counting method are its inherent subjectivity and the difficulty of standardisation between laboratories.
