To establish the sensitivity of anaerobic microorganisms, foreign and local researchers used a series of mixtures in liquid medium, and the disc method on hard agar. Most researchers show that the bacteriocytic dose of antibiotics to anaerobic microorganism increases greatly the bacteriostatic concentration. Many antibiotics are universal and deaden, in small concentrations, the growth of the majority of the stimulants of anaerobic infections. Microscopic tests of smears prepared from lungs of deceased pigs mainly from minute bronchial contents painted with Romanov stains, continuously showed microorganisms typical to leptospirosis. Besides erysipelas and leptospirosis, paratyphoid was found primarily in new born pigs.
