A naturally occurring chelate of iron in xylem exudate

Naturally occurring ehrlichiosis in Egyptian dogs

Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...

Translocation of iron citrate and phosphorus in xylem exudate of soybean.

Soybean plants, Glycine max (L.) Merrill, in standard solution received 2.5 mum ferric ethylenediamine di(o-hydroxyphenylacetate (FeEDDHA) and 0 to 128 mum phosphorus. Their stem exudates contained: 32 to 52 mum Fe, 120 to 5000 mum P, and 120 to 165 mum citrate. Electrophoresis of exudates with high P caused Fe trailing that precluded identification of any major form of Fe. Exudate with low P g...

Coinfection Associated with Naturally Occurring Cryptosporidiosis in Broilers

Transport of sodium into the xylem exudate of tobacco.

When tobacco (Nicotiana tabacum L. var. Virginia Gold) plants were pretreated with Na ((22)Na) several days before detopping, from 2.3 to 4.9% of Na previously accumulated in roots appeared in the xylem exudate in 7 days after detopping. Na from the external medium, however, was readily transported to the exudate. Moreover, the amount of the pretreatment Na that was transported to the exudate w...
