Hemolytic streptococci of the appendix vermiformis

Utilising the Appendix Vermiformis

Appendix Vermiformis Duplex.

Duplication of the alimentary tract is uncommon but duplication of the appendix is rare. Basu et al. (1959), in reporting 28 cases of duplication of the alimentary tract, had no case of appendix duplex. Picoli ( 1892) reported the first case of apendix duplex in a female patient who had associated anomalies of duplication of the entire large bowel, two uteri with two vaginae, ectopia vesicae an...

The Classification of Hemolytic Streptococci

1. The hemolytic variety of streptococcus is homogeneous, consisting of members that are nearly identical. 2. This homogeneity is most strikingly displayed in the behavior of these streptococci in the complement fixation reaction, all the strains studied reacting in a nearly identical way with all the antisera.

The effect of blunt abdominal trauma on appendix vermiformis.

OBJECTIVES Trauma and appendicitis are the most common conditions of childhood for which surgical consultation is sought in emergency departments. Occasionally, appendicitis and trauma exist together, which causes an interesting debate whether trauma has led to appendicitis. We aimed to evaluate our patients with traumatic appendicitis and to discuss their properties in the light of the literat...

The Conversion of Hemolytic Streptococci to Non-hemolytic Forms

From one strain of hemolytic streptococcus three forms were isolated, which produced three different degrees of hemolysis on the surface of blood agar in the presence of oxygen. The original form was moderately hemolytic; the glossy variant was more hemolytic than the original form; and the third form, obtained by passing the original culture through mice, was non-hemolytic. Under anaerobic con...
