Penicillins and cephalosporins are ineffective, because the organism lacks a cell wall. Macrolide resistance has been increasing throughout the world, with 0-15% resistance in Europe and the United States, 30% in Israel, and 90-100% in Asia, Doxycycline has been avoided in children younger than 8 years because of fear of tooth staining, but the US Centers for Disease Control and Prevention has stated that short courses of newer formulations of doxycycline do not cause tooth staining. Erythromycin is a macrolide antibiotic that is used in the treatment of staphylococcal and streptococcal infections. This agent acts by inhibiting bacterial growth, possibly by blocking dissociation of peptidyl t RNA from ribosomes and causing RNA-dependent protein synthesis to arrest. Clarithromycin is a macrolide antibiotic that reversibly binds to the P site of the 50S ribosomal subunit of susceptible organisms and may inhibit RNA-dependent protein synthesis by stimulating the dissociation of peptidyl t RNA from ribosomes, which results in bacterial growth inhibition. Doxycycline is a tetracycline antibiotic that is used to treat susceptible bacterial infections of both gram-positive and gram-negative organisms, as well as infections caused by Mycoplasma, Chlamydophilia, and Rickettsia organisms. This agent is as effective as erythromycin and other macrolides in the treatment of M pneumoniae infection. The degree of resistance may vary according to geographic area, patient population, and previous exposure to antimicrobial agents. If tetracyclines are relied upon as first-line drugs, consider alternative agents in the event of treatment failures. In vitro susceptibility testing is sometimes indicated for species recovered from a normally sterile body site, from hosts who are immunocompromised, or from persons who have not responded to initial treatment. Minimal inhibitory concentrations (MICs) for doxycycline are typically lower than those of tetracycline against these organisms. species within the urogenital tract and in some extragenital locations. Activity of quinolones is not affected by tetracycline resistance, making these drugs attractive alternatives for tetracycline-resistant species, and no systematic comparative evaluations have been performed on treatment regimens for extragenital infections in adults or infections in neonates. Treatment recommendations, including dosage and duration of therapy, are based largely on in vitro susceptibility data, outcomes of treatment trials evaluating clinical response to syndromes such as pelvic inflammatory disease and urethritis that may be due to genital species are primarily noninvasive mucosal pathogens in healthy hosts, they have the capacity to produce destructive and progressive disease.

They are indicated for use in moderate to severe inflammatory acne and should be used in combination with a topical retinoid and BP. Evidence supports the efficacy of tetracycline, doxycycline, minocycline, trimethoprim/sulfamethoxazole (TMP/SMX), trimethoprim, erythromycin, azithromycin, amoxicillin, and cephalexin. The tetracycline class of antibiotics should be considered first-line therapy in moderate to severe acne, except when contraindicated because of other circumstances (ie, pregnancy, ≤8 years of age, or allergy). The antibiotics of the tetracycline class work by inhibiting protein synthesis by binding the 30S subunit of the bacterial ribosome. This class also has notable antiinflammatory effects, including inhibiting chemotaxis and metalloproteinase activity. Previous guidelines recommended minocycline as superior to doxycycline in reducing Erythromycin and azithromycin have also been used in the treatment of acne.
