Webbassume that every specimen in a red type cover is, in fact, a type specimen. Recent digitization programs did not curate and verify the authenticity of specimens in type covers and now those digital images are widely available online. Yet some proportion of the specimens in type covers are not types at all: WebbCollection of specimens for culture differs in two ways from collection of specimens for routine analysis: 1. Avoiding contamination by the organisms on the skin is essential if misleading results and inappropriate therapy are to be avoided. 2. Although any small volume can be cultured, the probability of obtaining a WebbWe therefore see little justification for disruption and economic loss caused through suspension of tourism and recreational activities unless the epidemiological case is obviously very strong (section 4.2.1). This is most likely to be the case when virus is not thought to be on a site, and visitors come in very close proximity to wild birds. qld health interpreter service
