WebMetronidazole undergoes reduction in bacteria where it is metabolized to cytotoxic derivatives that bind to DNA, causing loss of the helical structure, strand breakage, and impairment of DNA function. It is active against obligate anaerobic bacteria; however, aerobic bacteria lack the reductive pathway necessary for its mechanism of activity. Webobligate aerobe Definition. Organisms that need oxygen for their growth are called obligate aerobes. With cellular respiration, these organisms utilize oxygen to metabolize compounds such as sugars, fats and obtain energy from them. Mycobacterium tuberculosis and Nocardiaasteroides are an example of obligate aerobes. WebNeomycin has activity against most gram-negative aerobes, and inhibits protein synthesis via binding to the 30S ribosomal unit. Although the mechanism of action for HE is assumed to be its antibiotic action, there is also evidence of villous atrophy, resulting in inhibition of intestinal glutaminase. descargar wow legion 7.3.5 completo
