The patient was taken to the district hospital with a stab wound to the thigh on the third day after the injury. The patient's condition is serious, there is significant swelling of the affected leg, an unpleasant smell and tissue necrosis around the wound. The development of gas gangrene caused by the anaerobic microorganism Clostridium perfringens is suspected. What morphological forms of bacteria can be detected by microscopy of the prepared preparations? What method of staining the pathogen should be chosen in this case? What tincture properties does Clostridium perfringens have? What features of pure culture selection will be taken into account during bacteriological examination of clinical material? . What types of identification should be used to confirm the species affiliation of the causative agent of gas gangrene? -What bacterial enzymes and toxins cause the development of gas gangrene?
