Chapter 11 : Diagnostic Medical Parasitology

MyBook is a cheap paperback edition of the original book and will be sold at uniform, low price.

Abstract:

The key to performance of diagnostic medical parasitology procedures is formal training and experience. The majority of diagnostic parasitology procedures can be performed either within the hospital setting or in an offsite location. The majority of physician office laboratories are not involved in diagnostic parasitology testing; however, as more molecular (nonmicroscopic) methods are developed, they may become more widely used in this setting. The specimen most commonly submitted to the diagnostic parasitology laboratory is the stool specimen, and the most commonly performed procedure in parasitology is the ova and parasite (O&P) examination, which comprises three separate protocols: the direct wet mount, the concentration, and the permanent-stained smear. Both flotation and sedimentation methods are available, the most common procedure being the formalin-ethyl acetate sedimentation method (formerly used was the formalin-ether method). Another simplified culture option has been developed for the isolation and identification of . This approach has proven to be much more sensitive than the examination of wet preparations alone and has been incorporated into use in many institutions with dramatic increases in the number of positive specimens identified.
