Abstract

Leptospirosis, anthropo-zoonosis ubiquitously widespread, is a social and economic problem still to be solved. The experimental and therapeutic employment of many antibiotics has largely been tested "in vitro" and "in vivo". In the following research we tried to evaluate, by experimental "in vitro" method, the sensitivity difference of three serovar strains of Leptospira interrogans to two macrolides, Erythromycin and Josamycin, compared with Penicillin. From standard cultures, previously treated with serial dilution of these antibiotics, the MIC and MSC, as quantitative parameters, have been stated. For the qualitative evaluation of the damages induced at ultrastructural level by the drug activity. Electron Microscopy investigations were performed on specimens from cultures treated for 6 hr with twice and tenfold the MSC. The present research confirms the good sterilizing efficaciousness "in vitro" of the tested macrolides (MSC less than 1 mcg/ml) and their different activity pathway.

Antimicrobial Resistance

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.
