A microbiological assay of penicillin in animal feeds.
The universal acceptance of the animal growth-promoting properties of some antibiotics and their wide usage in formulated commercial feeds requires that simple, rapid and reliable analytical methods be available for control purposes. Of the several antibiotics used in poultry rations, penicillin exerts its growth-promoting properties at levels considerably lower than other antibiotics (2 grams ...
متن کاملInvestigation of Aflatoxins in Imported Animal Feeds in Iran
Background: Aflatoxins (AF’s) are secondary metabolites produced by certain species of fungi on grains and animal feeds. Because of serious impact of AF’s on health, they should be monitored closely in potentially hazardous foods and feeds. Method: In this study, AF’s in imported animal feeds including cereals, corn gluten and meals (pastes derived from the cotton, colza and sunflower seeds) f...
متن کاملImproved turbidimetric assay for lysozyme in urine.
I describe an improved turbidimetric assay for lysozyme in urine. This method is simple, reproducible, linear over a 100-fold concentration range, sensitive to concentrations as low as 10 micrograms/L, and only commercially available products are required. Evaluation of urinary lysozyme concentration with this assay demonstrated a within-run and between-run CV of 9.9% and 4.8%, respectively, fo...
متن کاملPellet Quality in Animal Feeds
Pelleting costs money, and better pellets cost a little more. Payback comes in the form of convenience in handling the feed and more efficient use of the feed by the animal. Improved efficiency is due in part to heat processing which reduces pathogens and makes starches more digestible. A significant portion of the improvement is related to the physical form of the pellet. Durable pellets reduc...
متن کاملParaprotein interference with turbidimetric gentamicin assay
INTRODUCTION Gentamicin due to its low level of resistance and rapid bactericidal activity is commonly used to treat gram-negative bacteria. However, due to its toxic effects it needs to be monitored. To date, no interference has been reported with gentamicin assays. MATERIALS AND METHODS A patient with leg cellulitis and sepsis received a single dose of gentamicin and a sample was sent for g...
