Active substance: Norfloxacin
For this, 317 finishing pig herds were randomly selected from a database containing 1500 herds in the southern part of the Netherlands. In each herd 24 samples of fresh faeces were collected from two compartments with pigs close to market weight.
Per compartment 12 samples of faeces were pooled into one pooled sample. Pooled samples were cultured in duplicate.
Of a total of 115 Salmonella isolates tested, none were resistant to colistin, enrofloxacin, flumequin or gentamicin.
Automated liquid feeding of by-products, and membership of an Integrated Quality Control IQC production group were associated with a decreased risk of infection, while use of trough feeding was associated with an increased risk of infection.
It is necessary to test these presumed risk factors in intervention studies to evaluate their potency to reduce the Salmonella prevalence in finishing pigs and thereby reduce the risk of Salmonellosis in people consuming pork.
Algal toxicity of antibacterial agents applied in fish farming was investigated.
The growth-inhibiting effects of amoxicillin A, flumequine F, oxolinic acid OA, oxytetracycline hydrochloride OT, sarafloxacin hydrochloride SF, sulfadiazine SD, and trimethoprim T were investigated by a modified test procedure based on the procedure described in the ISO 8692 1989 protocol on three algal species: the freshwater cyanobacteria Microcystis aeruginosa, the freshwater green alga Selenastrum capricornutum, and the marine cryptophycean Rhodomonas salina.
Algal growth was measured as increased chlorophyll concentration by extraction with ethanol followed by measurement of fluorescence.
Results were quantified in terms of growth rates using the Weibull equation to describe the concentration response relationship.
At the respective doses, mean peak serum and plasma concentrations of 0.
The effective half-life of norfloxacin in serum and plasma is 3—4 hours. Steady-state concentrations of norfloxacin will be attained within two days of dosing.
Norfloxacin is least soluble at urinary pH of 7. Other companies initiated fluoroquinolone discovery programs in the aftermath of the publication of the norfloxacin patent.
Bayer Pharmaceuticals discovered that the addition of a single carbon atom to the norfloxacin structure provided another 4 to 10-fold improvement in activity.
