Scanning electron micrograph of the bladder epithelium with cystitis. Marked proliferation of epithelial cells.   Electron micrograph of bacteria in the bladder. E.coli is by far the most common pathogen involved in UTI. Baytril is active against the relevant Gram-negative and Gram-positive uropathogens, including mycoplasma. Cystitis. Marked destrucion of the bladder surface with accumulation of mucus. Baytril concentrates in mucus and reaches bacteria beneath layers of inflammatory material.   Proliferation of the renal pelvis epithelium with a marked increase of goblet cells in the mucosal region. Choosing an appropriate antiinfective avoids ascension of the infection to the upper urinary tract. Bladder surface with cystitis. Epithelial cells are covered by bacteria. Baytril reaches the infected tissues by from the bladder lumen via the urine, but also from the systemic circulation.   Aspect of a normal glomerulus. Capillary loops (x) and epithelial cells with their numerous processes (O) are visible. Baytril is well suited for the therapy of upper and lower UTI, because it is not nephrotoxic.
