ABSTRACT
Group B beta-hemolytic streptococci were isolated from the throats of 49 of 1,110 patients who had pharyngitis. Compared with patients whose throat cultures were negative for beta-hemolytic streptococci, those harboring group B were more likely to have enlarged tonsils (P less than 0.001), exudate (P less than 0.02), and tender enlarged anterior cervical lymph nodes (P less than 0.01). Group B should not necessarily be dismissed as a nonpathogen when identified in the pharynx of patients with exudative pharyngitis; laboratories which report beta-hemolytic streptococcal isolates from the pharynx only as group A or non-group A should be encouraged to perform definitive group identification of all beta-hemolytic isolates to further evaluate the role of other streptococcal groups as the causative agents for pharyngitis.

Cytomegalovirus (CMV) mononucleosis developed in two men after sexual contact with a woman who had had a similar but medically unverified illness several months before. The CMV was cultured from the woman's urine and cervix. Evidence of recent infection with CMV was also found in a new sexual contact of one of the men. However, roommates of the infected patients remained well, and serologic evidence of CMV infection failed to develop. This small outbreak suggests that CMV may be acquired as a venereal infection that sometimes progresses to the mononucleosis syndrome.
