Ciprofloxacin (Baytril, Enrotril) is a fluroquinolone, broad-spectrum antibiotic which is useful for treating a wide range of bacterial infections in poultry---both Gram-positive and Gram-negative bacterial organisms. Baytril is the veterinary-labeled form of ciprofloxacin. Fluroquinolone antibiotics are the drug of choice against Mycoplasma species, and most gram-negative bacteria, which includes Escherichia coli, and Salmonella; they aren't as effective against gram-positive bacteria. Due to its bitter taste, it may be necessary to mix the drug with another medium such as apple sauce or fruit juice to improve the taste. The drug is less effective when administered in drinking water.
Caution: Poultry taking this medication should be concurrently monitored for signs of secondary infections, especially those caused by sour crop.
