Microbial Phytase

Because digesta vary in pH in different gastrointestinal segments of poultry, exogenous phytase or xylanase may exhibit differences in activity along the gastrointestinal tract. Previous reports indicated that the stomach is the major site of exogenous microbial phytase activity, with no further activity found in the small intestine of piglets. Information regarding exogenous phytase or xylanase activity in the gastrointestinal tract of poultry is largely unavailable. Because exogenous phytase or xylanase activity in the digesta is extremely low, normal phytase or xylanase activity measurements are prone to errors resulting from background interference contributed by the exogenous inorganic phosphate or xylose in the digesta (Walsh et al., 1995). The aim of this study was to utilize electrophoresis activity stain to detect the activity of phytase or xylanase in different gastrointestinal segments of broiler chickens fed diets containing exogenous enzymes.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).
