Baytril Max® interferes with the DNA metabolism by inhibiting:
•
Topoisomerase II (DNA-girase)
• Topoisomerase IV
Ex.: E. coli DNA is about 1.300 μm lenght,
and is hold by a 2 μm long bacteria
Bacterial
Baytril Max: fast bactericide

Intact E. coli
After some minutes of
enrofloxacin application,
bacteria start “swelling”
and exploting
Size: 1000 x
After 7 horasall bacteria
exploted.
Bayer, Wuppertal Lab, Germany
Bacteria explote because of the uncoiled DNA expansion

Consequences of APP
Mortality
- Increased mortality by 1,75%
- Mortality in acute cases from 1 to 9% (Ø 3,1%)
- Mortality of 1% is equivalent to losses of 1.25€
per piglet, in consequence 3.87€
- Economical loss in Germany: 30-50 mio€/year

Baytril Max ®
• 86.8% recovery in 48h
• 97.9% of recovery was achieved with a second
application of Baytril Max®
• 90% of the treated animals shown a health improvement
12 h pt.
• Only one animal showed a slight loal reation at the
injection site (0.006%).
