Listeria monocytogenes strain H7762, a frankfurter isolate, was tested to determine whether it was able to survive at 4 degrees C in frankfurter pack fluid (exudate) and to determine whether food exposure affects its acid sensitivity. Cultures were sampled and tested for acid sensitivity by challenge with simulated gastric fluid (SGF). SGF challenges performed immediately after inoculation reve...

Much has been written concerning the mechanism and rate of movement of organic solutes in plants. The information concerning the physical properties and the composition of the liquid content of the phloem of plants is limited. The exudate from the sieve tubes of cucurbits has been studied most extensively. Crafts (5) reviewed the earlier literature and made extensive studies ( 1, 2, 3) on the m...

Exudate can be an excellent indicator of what is happening within a wound and, therefore, provides valuable information during patient assessment. The volume, consistency, and particularly odour and colour, of any exudate will inform the practitioner about bacterial contamination, infection and stage of healing (Hampton and Collins, 2003). However, in the chronic wound, exudate must be effectiv...

Detached pistils of Lilium longiflorum were labeled with d-glucose-U-(14)C 24 hours after anthesis and then sampled for the next 6 days to determine the appearance of label into exudate from the stylar canal and the stigmatic surface of the pistil. Results were obtained with unpollinated cv. Ace pistils and pollinated cv. Ace pistils, selfed or crossed (cv. Croft pollen). Limited data were also...

The literature on root exudate is replete with studies of factors influencing the quantity and cycle of its production. For the most part, this work has been done utilizing herbaceous species or vines, but citations are also available on some of the broad-leaved trees. Root exudate from conifers is rarely reported, but in the course of preparation of a thesis at the University of California it ...

BACKGROUND The need to incorporate stereopsis into a teleophthalmology system is controversial. Detection of hard exudate in the macula is suggested by some as an adequate surrogate for direct observation of retinal thickening. This study was designed to determine how accurate the detection of hard exudate is as a surrogate for stereoscopic detection of clinically significant macular edema (CSM...

The experiments reported above give evidence that in unresolved lobar pneumonia, the persistence of the exudate, followed by organization, depends upon the presence of serum in the exudate.

BACKGROUND A relatively new technology in wound care, negative pressure wound therapy (NPWT), has become widely used for the management of open abdomens and soft tissue wounds and provides a means to collect wound exudate to quantify protein loss. METHODS A prospective observational study was conducted in surgical, trauma, or burn patients (8 patients with open abdomens and 9 patients with ac...

The hydrogen ion concentration in the lesions of experimental pneumococcus infection has been estimated directly by pH determinations on exudates from living animals. For indirect evidence of an increase in hydrogen ion concentration within the lesions, the difference in sugar content between exudate and blood from animals with pneumococcus infection has been measured. With sanguinous exudate f...
