WOUND INFECTION Bacteria causing wound infection. A number of species of bacteria and a few fungi are included among the organisms that are known to produce wound infections. in animals. Usually, how- ever, the forms encountered are Micrococcus pyogenes. Streptococcus pyogenes, Bacillus pyogenes,* Bacillus pyogenes Suis (Grips), Bacillus pyogenes bovis (Kunnemann), a few other bacilli, more especially those belonging to the colon group, and a few species of the genus pseudomonas. Fungi, especi- ally the actinomyces, are rarely found in acute wound infections. Protozoa are very- rare excepting in specific dis- eases which they cause and where their entrance to the body is by means of the bites of insects. It is true in the domesticated animals as in pian, that the pyogenic bac- teria are the most common cause of wound infection. In open wounds they are often associated with a number of ordinary saprophytic bacteria. Frequently in closed lesions nonpathogenic organisms are present in *HoIt considers B. pyogenes to be identical with the bacillus of polyarthritis de- scribed by von Pods in 1897. He has found it present in a number of inflammations in animals which deviated somewhat from those caused by other pyogenic bacteria. These inflammations are characterized by their chronic and slow course and they are rarely followed by pyemia. The lesions differ from other abscess forming inflamma- tions in that before the necrosis of the tissue occurs, a distinct proliferation of the same takes place which leads to the formation of a tumorlike swelling. According to Grips, "The development of the abscess begins with the formation of small, solid tubercles of a spherical or linseed shape. These tubercles consist of a yellowish, hard tissue and show on section at the beginning,
