In the drug-suffused soil, all three crops absorbed substantial amounts of chlortetracycline
into their aboveground tissues, the researchers report in the November-December Journal of Environmental Quality.
This 2012 Deep Research Report on Global and China Feed Chlortetracycline
Industry is a professional and in-depth research report on the Global and China Feed Chlortetracycline
The rationale for including antibiotics in feed was constructed in the late 1940s and early 1950s when studies began to report a correlation between the use of antibiotics (mainly chlortetracycline
and oxytetracycline) in livestock, swine, and poultry with increased rates of animal weight gain (Jones and Ricke 2003).
It was once a recommended practice to ask a patient with blepharitis to apply chlortetracycline
eye ointment (Aureomycin) two to three times per day, and this should be continued for a month before perhaps being reduced to one to two times per week over the ensuing months.
We found 100 percent resistance in the largest slaughterhouse (Plant A) included in this study, which had declared a systematic use of chlortetracycline
in poultry feed between the 18th day and the 21st day to prevent digestive problems and enhance feed efficiency.
In the early 1980s, Batchelder laced the soil of young greenhouse plants with up to 180 parts per million (ppm) of chlortetracycline
or oxytetracycline, which are common livestock-growth promoters.
China, the world leader in the production of chlortetracycline
feed grade, chlortetracycline
hydrochloride, salinomycin and other animal health compounds.
After introducing Pharmgate's branded chlortetracycline

Each plant sample was cut aseptically into 1 cm long segments and placed on petri dishes containing potato dextrose agar (PDA) (Oxoid, UK) supplemented with chlortetracycline
HCL, 50 [micro] g/ml (Sigma, Germany) and streptomycin sulfate, 250 [micro] g/ml (Sigma, Germany).
Using the kits, the researchers found trace amounts of tylosin, tetracycline, and chlortetracycline
in surface and ground waters, field runoff, and swine manure.
It has zone diameters that indicate resistance to chlortetracycline
, oxytetracycline, demeclocycline, doxycycline, methacycline, and minocycline.
The antibiotics used included oxytetracycline, chlortetracycline
, enrofloxacin, neomycin and ciprofloxacin.

The tetracyclines, streptomycin, and gentamicin provided the greatest discrimination among E coli isolates; chlortetracycline
, cephalothin, and gentamicin resistance patterns provided the greatest discrimination between enterococcal strains.
