T cell and cytokine regulation of enterocyte apoptosis may also be important in the expulsion of nematodes, in particular T. spiralis and T. muris, which inhabit an intracellular niche. Certainly an increase in the number of apoptotic cells within the epithelium is observed around the period of expulsion of T. muris in resistant mouse strains (D. Artis, C.S. Potten and R.K. Grencis, unpublished). Apoptosis of host enterocytes may dislodge the nematode or perhaps expose vital feeding organs to immune attack, and so enhance expulsion. Whether enterocyte apoptosis results from the burrowing action of the worms or a tissue repair mechanism, or is involved in expulsion, remains to be investigated.

Mesozoans are all tiny organisms that have a very simple structure the body wall consists of a thin outer membrane that is dotted with large numbers of small cilia. When they beat, they provide a means of locomotion through the host animaTs body fluids. The vast bulk of the mesozoan body consists of egg and sperm cells. There are no specialized feeding organs, and nutrients and waste products pass directly across the cell wall. 

In animal feed organic acids were originally added to inhibit fungal contamination. However, in the past 40 years organic acids and various combinations have been investigated for potential bactericidal activity in feeds and feed ingredients (Ricke, 2003). 

Tin appears in seafood as butylated tin compounds and as methyltin compounds in leachate from plastics. Tributyltin was used for many years to control barnacles and other marine growths on the hulls of ships. These organisms attached to the ships increase the drag on the ships and make them less energy efficient. Tributyltin leaches from the paint into the surrounding waters and can reach levels of concern in eonfined areas, such as harbors. Filter feeding organisms, such as oysters and mussels, as well as detritus feeders accumulate butyltin compounds and these compounds...
